Fig. 1 a is a schematic view showing a Multiaperturabbildungsvorrichtung 10 according to one embodiment. The Multiaperturabbildungsvorrichtung 10 includes an image sensor 12, an array 14 of optical channels 16a-h, a beam deflecting device 8 and an optical image stabilizer 22. Each optical channel 16a-h includes an optical system 64a-h for imaging a part of the visual field of an entire field of view to an image sensor area 24a- h of the image sensor 12. the optical channels may be understood as a course of beam paths. The beam paths can be influenced by the 64a-h are arranged in the array 14 optics, for instance by scattering or bundling. The individual optical channels may each form a complete imaging optics and having at least one optical component or optical, such as a refractive, diffractive or hybrid lens, and can represent a detail of the device as a whole Multiaperturabbil plication recorded overall object. This means that one, several or all of the lenses 64a-h also combinations may be of optical elements. With respect to a, more or all of the optical channels may be disposed an aperture stop.
The image sensor portions 24a-h may for example be formed of one chip, the urnfasst a corresponding pixel array, wherein the image sensor regions on a common substrate and a common circuit substrate as a common circuit board or a common flex board may be mounted respectively. Alternatively, it would of course also possible that the image sensor portions 24a-h are each made of a part of a common pixel array that are continuously formed on the image sensor portions 24a-h extending, wherein the common pixel array is formed for example on a single chip. For example, only the pixel values of the common pixel array in the image sensor is then read out areas 24a-h. Several Mi-mixtures of these alternatives are of course also possible, such as the presence of a chip for two or more channels and another chips for still others channels or the like. In the case of multiple chips of the image sensor 12, these can, for example all together or in groups, or the like, for example, on one or more boards or be mounted circuit carriers. It is also an Lö-sung possible in which a single chip is used, which has many individual pixel arrays. Alternate embodiments have multiple chips, which in turn have individual pixel arrays.
The beam deflection device 18 is designed to deflect a beam path 26 of the optical channels 16a-h. The image stabilizer 22 is designed to permit, based on a relative movement between the image sensor 12, the array 14 and the baffle 18 an optical image stabilization along a first image axis 28 and along a second image axis 32nd The first image and the second image axis 28 axis 32 may be of an arrangement or orientation of the image sensor portions 24a-h and the image sensor being influenced 12th According to one embodiment, the imaging axes 28 and 32 are arranged perpendicular to each other and / or correspond to directions of extension of pixels of the image sensor portions 24a-d. The image axes 28 and 32 may alternatively or additionally specify an orientation along which a part of the visual field or the whole field of view are sensed or detected. In simplified terms it may be for the image axes 28 and 32 be a first or second direction in a captured image from the Multiaperturabbildungsvorrichtung 10. The imaging axes 28 and 32 have for example. A t angle of 0 ° to one another, for example be arranged perpendicular to each other in space.
An optical image stabilizer can be advantageous if during a detection process, while the partial fields or the total visual field are detected, the
Multiaperturabbildungsvorrichtung is moved 10 relative to the object region, whose field of view is detected. The optical image stabilizer 22 may be designed to counteract this movement, at least partially, in order to reduce a blur of the image or to prevent. For optical image stabilization along the imaging axis 28 of the optical image stabilizer 22 may be formed about a first relative motion 34 between the image sensor 12 to produce the array 14 and the beam deflecting 18th For optical image stabilization along the imaging axis 32 of the optical image stabilizer 22 is configured to produce a second relative movement between the image sensor 12, the array 14 and the beam deflecting 18th For the first relative movement 34 of the optical image stabilizer 22 has an actuator 36 and / or an actuator 37 for generating the relative motion 34 by moving the array 14 and the image sensor 12 along the imaging axis 28th In other words, even though the actuator 36 is illustrated as it shifts the array 14 in a translatory or moved, the actuator 36 may in accordance with further embodiments, alternatively or additionally be connected to the image sensor 12 and be adapted to the image sensor 12 relative to the array 14 to move. Alternatively or additionally, the optical image stabilizer may comprise an actuator 42, which is adapted to produce a translational motion 39a of the beam deflection device 18 along the imaging axis 28th The optical image stabilizer 22 is configured such that it that the relative movement occurs, the movements of the actuators 36, 37 and / or 42 executes between the image sensor 12, the array 14 and the beam deflection 18 34th That is, although the relative movement is shown in Fig. 1 a shown on the array 14 34, can alternatively or additionally, other components are moved. The relative motion 34 may be parallel to a line extending direction 35 and perpendicular to the beam paths executable 26th However, it may be advantageous to place the array 14 relative to the image sensor 12 in a translatory movement to 12 with respect to other components mechanically to charge such as an electrical interconnection of the image sensor little or not.
For generating the second relative movement of the optical image stabilizer 22 may be formed to have a rotational movement 38 of the beam deflection to produce 18 or to enable and / or a translational relative movement between the image sensor 12 and the array 14 along the imaging axis 32 and / or a translational relative movement between the array 14 and the beam deflecting device set bereitzu-18, for which purpose the actuators 36, 37 and / or 42 may be disposed. For the generation of the rotational movement 38 of the optical image stabilizer 22 may comprise the actuator 42. beispielswei- se, which is adapted to generate the rotational movement 38th Alternatively, the optical image stabilizer 22 may be formed to generate, using the actuator 42, a translatory movement of the image axis 39b along 32nd Based on the first relative motion 34 and / or 39a may be an optical image stabilization of an image along the direction parallel thereto, for example along or opposite to the image axis 28 are obtained. Based on the second relative motion 38 and / or 39b, an optical image stabilizer can be obtained along an image direction of rotation 38 is arranged in a main side plane of the image sensor 12 perpendicular to a rotation axis 44, approximately along the image-axis 32. A page can be used as side are understood to be compared or a large greatest dimension with other sites have. Alternatively or additionally, a focusing device such as, for example, in connection with FIG described. 3, be arranged, which is configured to change a focus of the Multiaperturabbildungsvorrichtung. Although, it is possible for obtaining the optical image stabilization, an embodiment of the optical image stabilizer 22 such that it controls the first and the second relative movement as relative translational movements, a configuration of the second relative movement may be advantageous as a rotational movement 38, as in this case, a translational movement can be avoided by components along the second image axis 32nd This direction may be parallel to a thickness direction of the Mul-tiaperturabbildungsvorrichtung 10 are, in accordance with some embodiments, is to be kept as low as possible. The rotational movement of such a goal can be achieved.
In simple terms, can be used vertically, the rotational movement 38 to the relative motion 34, in order to obtain the optical image stabilization along the second image axis 32 instead of a translatory movement. This allows an installation space can be saved to enable the translational relative movement perpendicular to the relative movement 34th For example, the relative translational motion can be arranged perpendicular to a thickness direction of the device, so that the apparatus having a small thickness, can be carried out that is thin. This offers advantages in particular in mobile devices, since they can run with a flat housing.
The ultiaperturabbildungsvorrichtung 10 has an electronic image stabilizer 41 that is formed to the sub-images that are mapped h-24a to the image sensor portions to stabilize electronically, that is, by manipulating the image data.
For this purpose, various methods can be used individually or in combination, such as electronic vibration reduction (electronic Vibration Reduction; e-VR), Coolpix 84, Anti-Shake DSP (Anti Shake DSP) and / or advanced Schüttelreduzierung (Advanced Shake Reduction - ASR) , The electronic image stabilizer 41 is formed off to a first partial image of the image sensing areas 24a-h of a first optical channel 16a-h of the array 14 in a first circumference to stabilize. Further, the electronic image stabilizer 41 may be formed by additionally a second partial image of the image sensing areas 24a-h of a second optical channel 16a-h of the array 14 in a second and different from the first circumferential extent, ie, channel individually to stabilize. The scope refers to an image correction, which is executed along the first and second image axis 28 and 32, wherein here also rotations about axes image and the like are included.
In embodiments of the electronic image stabilizer 41 is formed to the electronic image stabilization channel-individually for each optical channel, that is executed for each of the partial images of the image sensor portions 24a-h. This allows for the first and second optical channel 16a-h different imaging errors or channel-specific aberrations corrected.
The lenses 64a-h of the optical channels may have different optical properties from each other. One of mutually different optical property is, for example, obtained by manufacturing tolerances, so the optics 64a-h than ± 5%, or within ± 3% that in a tolerance range of at most ± 10%, with respect to one or more optical properties differ from one another, such as a Brennwei-th, like a visual field angle of an optical diameter or.
It has been recognized that in the context of production-related different optical properties of the lenses 64a-h, an optical image stabilization by a relative movement between the image sensor 12, the optical system 64a-h of the respective optical channel and the beam deflection device 18 causes the pictures that in 24a-d also change the image sensor areas different. This is at least partly due to the fact that the optical channels for all that is, equally channel global executed mechanical movement to achieve an optical image stabilizer to a different optical path changed by the optical systems 64a-h leads. The distinct optical properties now have different effects or even channel individually in the figures, the image sensor portions 24a-h from. In other
Words, result in particular from the different focal lengths of the channels channel, different image motions in the same acting for all the channels relative movements between the beam deflecting and / or array and / or image sensor. The combined with the optical image stabilization electronic image stabilization, this can be reduced, that is, at least partially offset or compensated. This will be illustrated with reference to the optical property of focal length. When two mutually different values of the optical lens focal length optics which are directed to the same overall field of view, the relative movement results in the context of optical image stabilization, that the viewing axis and / or direction of the optical channels are changed equally. Due to the different focal lengths in the optics 64a-h but the partial images move in the image sensor areas 24a-h different, which can lead to high computational effort or even artifacts when joining the partial images, the stitching.
The array 14 may for example comprise a carrier 47, pass through the optical channels 16a-h. For this purpose, the carrier 47 may be formed, for example, opaque and having transparent regions for the optical channels 16a-h. can within or adjacent to the transparent regions and / or at end portions thereof, the optics 64a-h of the optical channels may be arranged 16a-h. additionally to-the carrier 47 or, alternatively, may be formed transparent and have, for example, a polymeric material and / or a glass material. The optics (lenses) 64a-h can be arranged on a surface of the substrate 47, the imaging of the respective sub-field of view of the overall field of view on the respective image sensing area 24a-h affect the image sensor.
The actuators 36 and / or 42 may, for example, as a pneumatic actuator, a hydraulic actuator as a piezoelectric actuator, as a DC motor, a stepping motor (stepper motor), as thermally aktuierter actuator, an electrostatic actuator, an electrostrictive actuator, a magnetostrictive actuator or as moving coil actuator be formed.
The beam deflecting device 18 may be partially formed reflective. For example, the beam deflecting device 18 may include areas or ray deflection 46a-d, which are formed to deflect the beam paths 26 so that the deflected beam paths have a different from each angle, and detect one of each different part of the visual field of an entire field of view. The different angles by the beam deflection device 18 and / or the optimization
ken 64a-h 16 a-h are generated of the optical channels. For example, the regions 48a-d may be formed as facets of a facet mirror. The facets may have a different tilt with respect to each of the array fourteenth This can be a distraction, interference, control and / or scattering of the beam paths 26 allow towards different from each other arranged part of fields of view. Alternatively, the beam deflection device 18 can be configured as one or both sides reflective surface formed, for example, as a mirror. The surface may be flat or continuously curved or planar sections, formed and / or sections, discontinuous curved or planar formed. A deflection of the beam paths 26 may alternatively or additionally by means of the optics 64a-h of the optical channels 16a-h are obtained.
In other words, a relative movement to the optical image stabilization effect the same mechanical deflection in all channels of Multiaperturkamera. The Bildver-shift achieved that makes the actual mechanism of the optical image stabilization, but also depends on the focal length of the imaging optics of each channel from. therefore a realization is that in addition to the optical image stabilization, which is globally carried out for all channels, an additional channel-specific electronic image stabilization is introduced .. The beam deflection can be both for deflecting the viewing direction can also be used for optical image stabilization.
The beam deflection can over the range of all channels be flat, have a continuous or discontinuous profile and / or piecewise planar, that is faceted, being, with the transitions between individual continuous or discontinuous profiles may additionally comprise local masks to reduce the reflectivity or mechanical structures, in order to reduce image errors and to enable stiffening of the structure, so that motion-induced or thermally induced image errors may be low.
A switching between the first position and the second position of the beam deflection can be done in translation along the axis of rotation 44th A movement along the rotational axis 44 may be continuous or discontinuous, for example, bistable! be executed or more stable. This may for example be understood as a position discrete positions between which the beam deflecting device is moved 18th Simply stable, bistable or more stable positions can be obtained, for example, by the actuator 42 or other actuator is designed as a stepping motor. If the beam deflection device 18 is formed, for example, to be moved between two positions back and forth, one of the positions may for example be a rest position of the actuator or based thereon. The actuator can for example be adapted to the translatory movement with respect to a spring force run, which exerts a counter force on Errei-chen the respective other position, which moves at a removal of the force of the actuator, the beam deflecting back into their starting position. This means that a stable position can be obtained also in areas of a force diagram having no local power minimum. For example, it can be a force maximum. Alternatively or additionally, a stable position can be obtained based on magnetic or mechanical forces between the beam deflection device 18 and an adjacent casing or substrate. That is, the actuator 42 or other actuator for translating the beam deflecting device may be configured to move the beam deflecting device in a bistable or more stable position. Alternatively, may be provided for bistable arrangements of positions of simple mechanical stops that define two end positions between which a position circuit in the defined end positions.

A height of the box 55 along the direction 57 may be minimal and essentially by the expansion of the optical components of the imaging channels, ie, the Ar-rays 14, the image sensor 12 and the beam deflecting be dictated 18 along the direction 57th
A volume of the Multiaperturabbildungsvorrichtung may have little or minimal space between the planes 52a and 52b have.

Although terms used herein such as, left, right, up, down, forward or back used to improve clarity, these are to realize any limiting effect. It is understood that on a rotation or tilt in space these terms are based mutually interchangeable. For example, the x-direction of the image sensor 12 can be prepared starting towards the beam deflecting device 18 than in the front or understood forward. A positive y-direction can for example be stood up as comparable.

The focusing device 54 may include an actuator 58, which is adapted to be provide at an actuation to deform and / or a relative movement between the image sensor array 12 and the fourteenth Illustratively, this imaging device is for the 30-ultiapertur shown so that the actuator 58 is formed to shift to the array 14 along the positive and / or negative x-direction relative to the image sensor 12th For example, the array may be stored 14 on one side so that it experiences based on an actuation of the actuator 58 to move along a positive or negative x-direction and remains unmoved along a positive and / or negative z-direction substantially. An additional movement along the positive and / or negative z-direction for an optical image stabilizer can be obtained, for example, based on a 36 actuation of the actuator. approximately examples exporting-According to further the actuator 58 and the focusing means 54 is adapted to the relative movement between the image sensor 12 and the array 14 along the x-axis
to obtain based on a translational displacement of the image sensor 12 relative to the array fourteenth According to further embodiments, the image sensor 12 and the array can be moved fourteenth According to further embodiments, the Fo-kussiereinrichtung 54 comprise at least a further actuator. For example, to a first actuator and a second actuator on two opposite areas of the array 14 so that an actuation of the actuators a request to a support of the movable array 14 is reduced (alternatively or additionally to the image sensor 12). In addition, the actuator 58 or another actuator may be adapted to a distance between the one-line array 14 and the beam deflection 18 in the We-sentlichen or to hold exactly constant even when using no additional actuator, that is, to move in a periphery of the beam deflection 18 , such as the single-line array 14. the focusing device 54 may be formed to an autofocus function by a relative translational motion (focusing movement) between the image sensor 12 and to enable the array 14 along a surface normal of the image sensor 12th The beam deflection device 18 can thereby be moved by appropriate structural design or use of the actuator 42 or another actuator simultaneously for focusing movement. This means that a distance between the array 14 and the beam deflecting device remains unchanged and / or that the beam deflection device 18 at the same time or at different times in the same or a comparable extent as the focusing movement is moved so that at least at a time of recording of the visual field by the Multiaperturabbildungsvorrichtung unchanged compared with a distance before a change of focus. This can be done in such a way that the beam deflecting device is moved with the actuator 42 together, ie, simultaneously, 18, so that a distance between the array 14 and the beam deflecting device remains constant, or is compensated. This means that a distance between the array 14 and the beam deflecting device can remain unchanged 18 and / or in that the beam deflection device 18 at the same time or at different times in the same or a comparable extent as the focusing movement is moved so that the distance between array 14 and the beam deflection 18 at least at a time of recording of the visual field by the Multiaperturabbildungsvor direction compared unchanged at a distance in front of a change in focus. Alternatively, the beam deflection device 18 may be dormant or excluded from the auto focus motion.
The actuator 58 may, for example, as a piezoelectric actuator, such as a bending beam (such as a bimorph, trimorph or the like) be executed. Alternatively or additionally, the focusing means can comprise 54 a voice coil actuator, a pneumatic actuator, a hydraulic actuator, a DC motor, a stepper motor, a thermally refreshes-ierbaren actuator or bending beam, an electrostatic actuator, an electrostrictive and / or a magnetostrictive actuator.
As was the same in connection with the image stabilizer and an arrangement in the plane 48 or in a region between the planes 52a and 52b described above, the at least one actuator 58 of the focusing device 54 may be at least partially disposed between the planes 52a and 52b. Alternatively or additionally, be arranged to the minimum one actuator 58 in a plane in which the image sensor 12, the array 14 and the beam deflection are arranged 18th For example, the actuator 58 of the focusing means 54 along the thickness direction 57 are perpendicular to the plane 48 in which the image sensor 12, the array 14 and the beam deflecting device 18, at most 50% of the dimension of the actuator 58 of the focusing means 54 along the thickness direction 57 protrude from the area between the planes 52a and 52b. According to embodiments, the actuator extends at most 30% from the area between the planes 52a and 52b out. According to another embodiment of the actuator 54 protrudes out by a maximum of 10% of the area or is located entirely within the area. This means that along the thickness direction 57 no additional space needs required for the focusing means 54, which is advantageous. Has, for example the array 14, a transparent substrate (support) 62 arranged thereon lenses 64a-d, so may be a dimension of the array 14 and the Multiaperturabbildungsvorrichtung 30 along the thickness direction 57, if necessary, be low or minimal. Referring to Fig. 2a, this may mean that the cuboid has a small thickness along the direction 57 or 55 that the thickness of the substrate 62 is unaffected. The substrate 62 may be passed by the used for the imaging in the different optical channels optical paths. The optical channels of the Multiaperturabbildungsvorrichtung can traverse 12, the substrate 62 between the beam deflection device 18 and an image sensor.
In the lenses 64a-d may be, for example, in liquid lenses, ie, an actuator can be adapted to the lenses 64a-d to control. Liquid lenses can be adapted to individual channel basis, the power, and thus the focal length and able to adapt and vary.
Fig. 4a shows a schematic perspective view of a Multiaperturabbildungsvor direction 40 according to an embodiment. Compared with the Multiaperturabbil plication device 10, the array 14 is formed, for example, one line, that is, all of the optical channels 16a-d may be arranged along a row direction of extension of the array 14 in a single line. The term single line can mean an absence of additional lines. A one-line embodiment of the array 14 allows a small dimension of the array and possibly the Multiaperturabbildungs device 40 along the thickness direction 57. The optical image stabilizer comprises actuators 36a and 36b, which together form the actuator 36, that is, a herein two described Bener actuator can also be implemented by a plurality of actuators or actuators and / or more actuators can be combined into a common actuator.
The Multiaperturabbildungsvorrichtung 40 may be configured to detect based on the beam deflection to 18 visual fields in mutually different directions. For example, the beam deflecting device a first position or position Pos1 and a second position or position may have Pos2. The beam deflection can be based can be switched to a translational or rotational movement between the first position Pos1 and Pos2 the second position. For example. , the beam deflecting device 18 along the line extending direction of the z-line array 14 can be moved translationally as indicated by a translational movement 66th The translational movement 66 may, for example, be substantially parallel to a line direction of extension 65, along which the at least one row of the array 14 is disposed. The translatory movement can, for example, be useful to different facets in front of the optics of the optical channels to place 16a-d, in order to obtain different directions of view of the Multiaperturabbildungsvorrichtung 40th The beam deflecting device 18 may be designed to deflect in the first position Pos1 the beam paths 26a-d in a first direction, for example at least partly in a positive y-direction. The beam deflection device 18 can be-det ausgebil to in the second position Pos2 the beam paths 26a-d, that each optical channel 16a-d, such as to direct in a different therefrom direction at least partially along the negative y-direction. For example, the actuator 42 may be configured to move the beam deflecting device 18 from the first position to the second position Pos1 Pos2 to based on a movement of the beam deflection device 18 along the direction of movement 66th The actuator 42 may be adapted to the translatory motion along the direction of movement 66 with the rotational movement 38 to
overlap. Alternatively, the Multiaperturabbildungsvorrichtung 40 may also comprise a further actuator, which is designed to move this to the beam deflection device along the direction of movement 66 or opposite.
As described in connection with Fig. 2b, the actuator 42 may be configured to the first or second position of the beam deflecting device 18 on egg ner rotation to obtain based thereof. The movement between the first position Pos1 and Pos2 the second position may also be superimposed on the translational movement along the direction 66 with the rotation 38 for both a rotational movement for switching between the positions as.
FIG. 4b is a schematic representation showing an overall visual field 70 as it is detectable, for example, with a previously described Multiaperturabbildungsvorrichtung, such as the Multiaperturabbildungsvorrichtung 10, 20, 340 or 40, wherein about the Multiaperturabbildungsvorrichtung 10, the total field of view 70 also in a higher or lower number of part visual fields 72a-d may be broken. The optical paths of the optical channels of the Multiaperturabbildungsvorrichtungen may be d 72a-steerable mutually different partial fields of view, wherein each optical channel is a part of the visual field 72a-d can be assigned. For example, overlap the partial fields 72a-d with each other to allow individual to a concatenation partial images to an overall image. Various, the Multiaperturabbildungsvorrichtung a four number of optical channels on the total face panel 70 may have a different number of part of four fields of view. Alternatively or additionally, at least part of the visual field 72a-d by a second or a higher number of optical channels in a higher number of modules (Multiaperturabbildungs) devices are detected to stereo, Trio- build Quattro cameras to thereby three-dimensional object data to be able to record. The modules can be designed, individually or as a coherent system, and be arranged at any point in a housing of the Multiaperturabbildungsvorrichtung. The images of the different union among modules, which together form the stereo, trio or Quattro cameras may be shifted by a fraction of a pixel, and may be designed to implement methods of the super-resolution. feidern part face a number of optical channels and / or a number of Multiaperturabbildungsvorrichtungen and / or a number of, for example, arbitrary and can be a number of at least two, at least three, at least four, have at least ten, at least 20 or an even higher value. The optical channels of the further row can also take overlapping partial areas, and together cover the entire field of view, respectively. This makes it possible to obtain a stereo, trio, Quattro-, etc. structure of array cameras, which consist of channels, which partly overlap and cover the whole field of view within their partial grouping.
Fig. 4c is a schematic perspective view of the Multiaperturabbildungsvor direction 40, of which an advantageous embodiment using a combination of optical image stabilization and electronic image-stabilization is explained. The optical image stabilizer 22 includes actuators 36a, 36b and 42, wherein the actuators are formed 36a and 36b, to reach the optical image stabilization of the images of the partial fields in the image sensor areas 24a to 24d by a displacement of the array 14 along the row direction of extension 65th Further, the optical image stabilizer is, for example, formed to an optical image stabilization along the imaging axis 32 to be obtained by the rotational movement of the 38th For example. have the optics 64a-d of the array 14 is a ί to f within a tolerance range of at most 10%, at most 5% or at most 3% of mutually different focal length 4 on. The channel global rotational movement 38 leads in conjunction with the different focal lengths f | to f 4 to a different displacement of 69i to 69 4 of the images in the image sensor areas 24a-d. This means that the optical image stabilizer 22 obtained by the canal global rotation Move ung 38 different effects in the figures, so that at least a representation one, several or all of the pictures from a theoretical error-free state. The optical image stabilizer 22 can be formed to the deviations of all the images to minimize global, but which can cause errors occur in each of the images. Alternatively, the optical image stabilizer 22 may be formed to have a reference image in one of the image sensor regions select 22 and 42 carry out the control of the actuator so that the image in the reference image or reference channel is exactly as possible, which may also be referred to as error-free. This means that through the global channel optical image stabilization, a channel can be kept free of errors based on the influence image direction, while the other channels due fi due to the different focal lengths to f 4 different from this reference image. In other words, a channel with the mechanical realized optical image stabilizer is corrected, has an action for all channels, but does not consider all channels stable. These other channels are corrected in addition to the electronic image stabilization.
The electronic image stabilizer 41 may be formed to a channel-individual electronic image stabilization in each channel according to a predetermined functional relationship be performed, the and depends on the relative movements between the image sensor 12, the array 14 and the beam deflecting 18th The electronic-see image stabilizer 41 can be formed to each image individually, and to stabilize individually. The electronic image stabilizer 41 can be used for this global values, such as the camera shake or the like, to increase the visual quality of the images. It is particularly advantageous when the electronic image stabilizer 41 is formed to carry out an electronic image correction on the basis of a reference image of the opti-see image stabilizer 22nd The different focal lengths the functional relationship between the different changes in the figures by the optical image stabilization in a linear shape preferably provide, such as in the form:
Figure error = f (f "relative movement)
that is, the global aberration or relative to the reference channel can be represented as a function of the focal length or focal length differences and the relative movement carried out for changing the viewing direction or optical image stabilization. The elekt-tronic image stabilizer 41 can be a scale or relative movement between the image sensor 12, array 14, and beam deflecting device 18 with the focal lengths f | relative to f or focal length differences link to the reference channel, to get a reliable information about the executed electronic image stabilization, and to the functional relationship to produce and / or utilize. Since the necessary th of optical properties and / or the functional relationship can be obtained during calibration. The orientation of images to each other for determining a displacement of an image over another image can also be performed by determining a matching feature in the images of the partial fields, such as edge contours, object sizes or the like. This can, for example, by the electronic image sensor 41 to be identified, which may be further adapted to provide the electronic image stabilization based on a comparison of motions of the feature in the first and second image. The channel-specific electronic image stabilization can be made of image detail thus by a channel-specific image analysis of the movement.
Alternatively, or in addition to a comparison in different images, a comparison of the feature within the same image can be performed, in particular to two temporally spaced images or frames. The optical image stabilizer 41 may be adapted to identify in the corresponding field at a first time and at a time a matching characteristic, and to provide based on a comparison of motions of the feature to the electronic image stabilization in the first image. The comparison can example. Specify a displacement by which the characteristic has been moved by a relative movement and to which the image is to push back to correct the image defects at least partially.
The optical image stabilizer can be used to create an image of the imaged part of the visual field of a reference channel, such as the image in the image sensor area 24 to stabilize. The electronic image stabilizer is, for example, 41 are formed to an image stabilization channel individually for different from the reference channel optical channels that map to the image sensor sections 24b, 24c and 24d to perform. The Multiaperturabbil plication device may be adapted to the reference channel to stabilize exclusively optical. That is, in one embodiment, can be achieved in the reference channel a sufficiently good image stabilization by the mechanically generated optical image stabilization is used alone. For the other channels to compensate fully to the above-described effect of insufficient optical image stabilization as a result of focal length differences part or an electronic image stabilization, in addition takes place, wherein the electronic stabilization is performed individually in each channel.
According to another embodiment, it is also possible that each channel of the Multiaperturabbildungsvorrichtung has an individual electronic image stabilization. Carried out individually for each channel of Multiaperturabbildungsvorrichtung electronic image stabilization can be carried out in such a way that a defined functional relationship is used between the realizable image shifts in the individual channels. For example, the displacement along the direction 32 is in a channel of the 1-fold, the 1, 007-fold, the 1, 3-fold or 2 or 5 times the displacement along the direction 32 in a different figure. can Furthermore, this channel-associated functional relationship of the relative movements between the beam deflecting and / or array and / or Biidsensor depend, this may be linear or may correspond to an angular function, the capitalization ro-tationswinkel the beam deflecting device on a periphery of the electronic Bildstabi- along the image direction maps. An identical connection can be obtained for the device 28 with the same or different numeric values.
realized the relative movements of entspre-sponding applies to all embodiments, additional sensors, such as gyroscopes, among others, are detected or can be derived from the captured image data of one, several or all channels. These data or information can be used for the optical and / or electronic image stabilizer to be used, which means that the Multiaperturabbildungsvorrichtung example. Configured to receive a sensor signal from a sensor, and with respect to the sensor signal an information related to a relative movement tiaperturabbildungsvorrichtung Mul-between which and the object is correlated to evaluate, and to a driving of the optical and / or electronic image stabilizer run using this information.
The optical image stabilizer can be formed to the optical image stabilization along the imaging axes to obtain 28 and 32 different from motion components, such as the array 14 for the stabilization along the direction 28 and the rotation 38 of the beam deflection device for the stabilization along the direction 32. In both cases affect differences in the optics 64a-d out. The foregoing Ausführun-gen regarding the electronic image stabilization can be implemented for both relative movements. In particular, a viewing enables the directions 28 and 32 separated from each other a consideration of different deviations between the lenses 64a-d along the directions 28 and 32nd
Embodiments described herein may have a common image axis 28 and / or 32 for use, the partial images in the image sensor areas 24a-d. Alternatively, the directions can also vary and be converted into each other.
FIG. 5a is a schematic diagram showing a beam deflection device 18, which is formed as Ar-ray of facets 46a-h. If the beam deflection device 18, for example positioned in the first position, so can the facets 46a-d indicated by the numerals 1, 2, 3 and 4 respectively deflect the beam paths of four optical channels in a first direction. are, the beam deflection device 18 to the second position, so the optical path of each optical channel based on the facets 46e-h in the second direction is deflected, as is indicated by numerals 1 ', 2', 3 'or 4'. The facets 46a-d and 46e-h, for example, referred to as advertising arranged in blocks.
the. For the translational movement of the Strahiumlenkeinrichtung 18 along the translational direction 66 a distance 88 can be covered, which substantially corresponds to a length of extension of the number of directional line-Erstreckungs of the optical channels along the 65th According to the embodiment of Fig. 4a, this is an expansion of four optical channels beispielswei-se along the row direction of extent 65. According to a further embodiment, the number of beam deflecting elements a multiple of the optical channels may be different. At least one beam deflection element may be formed in a position of Strahiumlenkeinrichtung or arranged to beam paths of at least two optical channels to deflect.
Fig. 5b shows a schematic view of the Strahiumlenkeinrichtung 18, wherein the facets 46a-g compared with the representation in Fig. 5a have a different from each other sorting. The Strahiumlenkeinrichtung shown in Fig. 5b has an alternating arrangement of the optical channels 46a-g for each optical channel, as shown by the sequence 1, 1 ', 2, 2', 3, 3 ', 4 and 4'. This allows a distance 88 'along which the Strahiumlenkeinrichtung 18 is moved to be switched between the first position and the second position. The spacer 88 'may be compared with the distance 88 in FIG. 5a be low. For example, the distance 88 'substantially to the distance between two adjacent optical channels of the array 14 may entspre-chen. Two optical channels can, for example, have a distance or a gap from one another which at least substantially corresponds to a dimension of a facet along the acting direction 65. The spacer 88 'may also be verscheiden thereof, for example. When a beam deflection element is formed in a position of Strahiumlenkeinrichtung or arranged to beam paths of at least two optical channels to deflect.
Referring to Figs. 6a-f advantageous embodiments of the Strahiumlenkeinrichtung 18 will be described. The remarks point to a number of benefits that can be executed with each individually or in any combination, but not intended to be limiting.
FIG. 6a is a schematic side sectional view showing a Strahlumlenkelements 172, which as one of the Strahlumlenkbereiche be used in described herein beam deflecting 46th The beam deflector 172 may be d 16a-effective and have a cross-sectional polygonzugartigen for one, a plurality or all of the optical channels. Although a triangular cross section is shown, it can also be a loading
liebiges other polygon act. Alternatively or additionally, the cross section may also have at least one curved surface, wherein the special-reflecting surfaces at an at least partially planar configuration may be advantageous in order to avoid aberrations. The two main sides 174a and 174b can be inclined by an angle δ to each other. can δ the angle has a value between 1 ° and have 89 °, preferably has a value between 5 ° and 60 ", and particularly preferably to a value between 10 ° and 30 °. The main sides 174a and 174b are thus preferably at an angle of at most 60 ° arranged inclined to one another.
The beam deflector 172 includes, for example, a first side 174a, a second side 174b, and 174c on a third side. is at least two sides, such as the sides 174a and 174b are formed reflective so that the beam deflector 172 formed on both sides reflective. At the sides 174a and 174b may be the main sides of the Strahlumlenkelements act 172, so pages whose area is larger than the side 174c.
In other words, the beam deflector can be formed reflective wedge-shaped and both sides 172nd The surface 174c opposite, ie between the surfaces 174a and 174b, a further surface can be arranged, but is significantly smaller than the area 174c. In other words, the wedge formed by the surfaces 174a, 174b and 174c does not extend any pointed to, but is provided on the tip side with a surface area and thus blunted.
Fig. 6b shows a schematic side sectional view of the Strahlumlenkelements 172, in which a suspension or a displacement axis 176 of the Strahlumlenkelements described 172. The displacement axis 176 about which the beam deflector 172 may be movable in the beam deflection device 18 rotationally and / or translationally, can ex-centrically with respect to a centroid 178 of the cross section to be shifted. The centroid may alternatively be a point, which describes the dimension of the hälftige Strahlumlenkelements 172 along a thickness direction 182 and along a direction 184 perpendicular thereto.
The page 174a may have a surface normal 175a while the page 174b may have a surface normal 175b. Is used a rotary movement around the axis of displacement 176 to switch the beam deflecting device between the first position and the second position, the rotational movement of the beam deflecting device can be designed so that between the two
Positions an orientation is completely facing according to which a major sides 174a or 174b of the array 14, is avoided, as described in connection with Fig. 2b. This can also be understood that during a change between the first and the second operating state or position by the rotational movement of the surface normal a γ 175a and the surface normal 175b of the second main side at each time point in Fig. 2b as an angle and γ 2 angle designated obtained from at least 0 ° to a direction toward the image sensor, which may contain parallel to a surface normal of the image sensor. Thus it can be avoided that one of the angle is 0 ° or 180 °, resulting in a high or approximately maximum extension of the beam deflection can mean along the thickness direction.
The displacement axis 176 may, for example, along a thickness direction 182 unchanged and any offset in the direction perpendicular thereto have. Alternatively, an offset along the thickness direction 182 is conceivable. The displacement can, for example, be such that the sliding axis 176, a higher travel range is obtained with a rotation of Strahlumlenkelements 172, than with a rotation about the centroid 178. Thus, by the displacement of the axis of displacement 176 of the way to the edge is moved between the sides 174a and 174b at a rotation at the same angle of rotation compared with a rotation about the centroid 178 increase. Preferably, the beam deflector 172 is positioned so that the edge, so the pointed side of the wedge-shaped cross-section, the image sensor faces between the sides 174a and 74b. By small rotational movements thus a respective other side 174a or 174b can deflect the beam path of the optical channels. Here it is clear that the rotation can be performed so that a space required for the beam deflection is low along the thickness direction 182, since movement of the Strahlumlenkelements 172 so that a page is perpendicular to the image sensor, is not required.
The side 174c can be referred to as minor side or back. Several ray deflection can be interconnected such that a connecting element is arranged on the side 174c or passes through the cross section of the ray deflection, and is therefore located inside the ray deflection, about 176 in the area of the axis of displacement can in particular be arranged in the holding member so that it, that is not or only to a minor extent, at most 50%, at most 30% or at most 10% projects beyond the beam deflector 172 along the direction 182, so that the retaining element is not the extension of the overall construction
increases along the direction 182 or determined. The dimension in thickness direction 182 can alternatively be determined by the lenses of the optical channels that is, these have the minimum of the thickness-defining dimension.
The beam deflector 172 may be formed of glass, ceramic, glass ceramic, plastic, metal or a combination of these materials and / or other materials.
In other words, the beam deflector 172 may be arranged so that the tip, that is, the edge between the main sides 174a and 174b faces the image sensor. An attitude of ray deflection can be such that it takes place only on the back or inside the ray deflection, ie the main pages are not covered. A common retaining or connecting member may extend across the rear 174c. The axis of rotation Strahlumlenkelements 172 may be disposed eccentrically.
Fig. 6c is a schematic perspective view showing a Multiaperturabbildungsvor-direction 190, the image sensor 12, and a single-line array 14 of adjacent optical channels 16a-d comprises. The beam deflection device 18 comprises a number of beam deflecting elements 172a-d, which may correspond to the number of optical channels. Alternatively it can be arranged beam deflecting of a smaller number, such as when at least one beam deflector of two optical channels is used. Alternatively, a higher number may be arranged, for example, when a changeover of the turning direction of the beam deflection device 18 takes place through a translational movement, as described in connection with FIGS. 5a and 5b. Each beam deflection element 172a-d may be associated with an optical channel 16a-d. The ray deflection 172a-d may be formed as a plurality of elements 172nd at least two, more or all of ray deflection be formed with one another 172a-d integrally alternatively.
FIG. 6d shows a schematic side sectional view of the Strahlumlenkelements 172 whose cross section is formed as a free-form surface. Thus, the side 174c may have a recess 186, which enables attachment of a retaining member, the recess 186 may be formed as a projecting element, such as a spring of a tongue and groove system. The cross-section further includes a fourth side 174d, which has a smaller surface area than the main sides 174a and 174b and selbige connects with each other.
FIG. 6e shows a schematic sectional side view of a first Strahlumlenkelements 172a and one behind it in Darsteliungsrichtung second Strahlumlenkelements 172b. The recesses 186a and 186b can be arranged so that they are substantially congruent so that an arrangement of a connecting member in the recesses permits is.
Fig. 6f shows a schematic perspective view of the beam deflection device 18, for example. Strahlumlenkelements four 172a-d comprises 188 are connected with a connecting ele-ment. The connecting member may be used so as to be translationally by an actuator and / or rotationally movable. The connecting member 188 may be integrally formed and extend 172a-d via an extension direction, such as the y-direction, on or in the beam deflecting elements. Alternatively, the connecting element 188 can also be made with at least one side of the direction Strahlumlenkein be connected 18, such as when the ray deflection are formed integrally 172a-d. Alternatively, a compound having an actuator and / or a compound of the ray deflection 172a-d also in any other way be made, as by bonding, optical contact or soldering.
Fig. 7 is a schematic perspective view showing an imaging system 60 according to one embodiment. The imaging system 60 includes the Multiaperturabbildungsvorrichtung 10. According to further embodiments includes the imaging system 60 alternatively or additionally to the Multiaperturabbildungsvorrichtung 10 at least one Multiaperturabbildungsvorrichtung 10 ', 20, 30 40. The imaging system 60 is a flat housing 92. includes the flat housing 92 includes a first expansion 94a along a first direction a housing. The flat housing 92 further includes a second extension 94b b along a second direction and housing a third extension 94c c along a third housing direction. For example, the housing may be a direction parallel to the thickness direction 57 in space. 94a, the off-stretching of the flat housing 92 along the housing direction can be understood as a smallest dimension of the flat housing 92nd Compared with the smallest extension of other extents may 94b and / or 94c b along the other housing directions or at least c has a value three times, at least a five-fold or at least a seven-fold value compared to the extension 94a along the housing towards a comprise. In simplified terms, the extension 94a smaller, b along other directions housing substantially smaller or possibly an order of magnitude smaller than other expansions 94b and 94c or c.
The flat housing 92 may included one or more apertures 96a-b through which the beam path 26 and / or 26 'therethrough be deflected, for example, based on the beam deflection of the Multiaperturabbildungsvorrichtung 10. The aperture may, for example, be electrochromic shutters and / or in a region of the display be disposed.
The imaging system 60 may be configured as portable device. For example, the imaging system 60 may be a portable communication device such as a mobile telephone or a so-called smart phone, a tablet computer, or a portable music player to be. The imaging system 60 can as a monitor, for instance for use in a navigation, multimedia or television system may be implemented. Al-ternatively, or additionally, the imaging system 60 behind a reflective surface such as a mirror may be disposed.
In the field of mobile communication devices, an arrangement may a Multiaperturabbildungsvorrichtung 10, 10 ', 20, 30 and / or 40 may be advantageous, as based on the arrangement of components along the long sides of the housing 94b and / or 94c along the expansion of the Multiaperturabbildungsvorrichtung 94a housing direction can be small, so that the imaging system 60 may comprise a small extension 94a. In other words, a relative two-dimensional lateral movement of the image sensor and lens, in conventional systems, a two-dimensional angle-länderung the visual field (corresponding to one scanning) effect, be replaced by a one-dimensional change of the viewing direction and a rotational movement. A one-dimensional change of the viewing direction, by changing the orientation of the mirror (beam deflecting) with respect to the optical axis take place (Zeilenerstre-ckungsrichtung) of the imaging channels by the rotatably mounted mirror is placed in a different orientation, wherein the axis of rotation of the mirror perpendicular or nearly perpendicular may extend to the optical axes of the imaging channels. In order to adapt the viewing direction perpendicular to the above-described direction of the image sensor and / or lens array (array of the optical channels) laterally movable to one another. In combination of both movements a two-dimensional optical image stabilization can be achieved.
To enable a small height, which are arranged to realize the movement of components (for example) actuators) and subsystems such as image processing, if necessary, only the side, front and / or behind the area defined by the imaging beam path space be arranged, that is, between the be arranged planes 52a and 52b, and in accordance with embodiments not above or below. This allows a spatial separation of the moving units (actuators) for the optical image stabilization. This allows a reduction in the number of required components are obtained and thus a manufacturing cost of camera systems to be low and a significant reduction in height compared to conventional In-built can be achieved. Referring to Fig. 2a, a contrast to prior art systems may be that the lenses (lenses) of the optical channels can substantially define the spacing of the planes 52a and 52b. This allows a low overall height of the device, which is advantageous. In conventional systems, a principal plane of the lenses is parallel to the planes 52a and 52b, whereas the principal plane of the optics of the array is arranged orthogonally thereto.
Fig. 8 is a schematic perspective view showing an apparatus 80 comprising a housing 72 and a first and a second Multiaperturabbildungsvorrichtung 10a disposed in the housing 72 Multiaperturabbildungsvorrichtung 10b. The device 80 is adapted to the total field of vision 70 at least partly, approximately, to capture stereoscopic-obligations Multiaperturabbildungsvorrich with in the overlap of the detection areas. The overall field of view 70 is, for example, on one of the main page 74a disposed remote from the housing 74b. For example, the Mul-tiaperturabbildungsvorrichtungen 10a and 10b, the total field of vision 70 by transpa bond areas 68a and 68c detect, wherein arranged in the main side 74b of aperture 78a and 78c are at least partially transparent. In the main side 74a disposed apertures 78b and 78d of the transparent regions may 68b and 68d at least partially occlude optical, so that an amount of stray light from one of the main 74a facing side, which can the images of the Multiaperturabbildungsvorrichtungen 10a and / or distort 0b, at least reduced is. Although the Multiaperturabbildungsvorrichtungen are shown 0a and 10b are arranged spatially spaced apart from one another, which can be arranged Multiaperturabbildungsvorrichtungen 10a and 10b also are spatially adjacent or in combination. For example. the single-line arrays may be Abbüdungsvorrichtungen 10a and 10b side by side-net angeord or parallel to each other. The single-line arrays may form rows one another, each multi-aperture imaging device comprising a single-line array 10a and 10b.

Alternatively, or in addition to the Multiaperturabbildungsvorrichtung 10a and / or 10b, at least the Multiaperturabbildungsvorrichtung 10, 10 ', 20, 30 and / or 40 may be disposed. Such common elements, such as the beam deflecting device or the array can be used by a common optical image stabilizer, since, for example. A movement of the beam deflecting optical channels of several modules function as optical image stabilization can act. Accordingly, the optical image stabilizer may be carried out jointly for multiple modules and / or a common reference channel to be used for multiple modules.

Fig. 9 shows a schematic configuration comprising a first Multiaperturabbildungsvorrichtung 10a and a second 10b Multiaperturabbildungsvorrichtung as eg. May be disposed in the imaging system 80. The arrays 14a and 14b are formed in one line and form a common line. The image sensors 12a and 12b may be mounted on a common substrate or on a common circuit board as a common circuit board or a common flex board. Alternatively, the image sensors 12a and 12b may also comprise of mutually different substrates. Various mixtures of these alternatives are of course also possible, such as comprising Multiaperturabbildungsvorrichtungen have a common image sensor, a common array and / or a common beam deflection device 18 and other Multiaperturabbildungsvorrichtungen, the separate components. Advantageously, at a common image sensor, a common array and / or a common beam deflecting device is that movement of a respective component at a high precision by controlling a small amount of actuators can be obtained and can be reduced or avoided synchronization between actuators. Further, a high thermal stability can be obtained. Alternatively or additionally, other and / or different from one another can Multiaperturabbil-
have dung devices 10, 10 ', 20, 30 and / or 40 a common array, a common image sensor and / or a common beam deflection.
FIG. 10a is a schematic representation of a starting point of an execution form of the electronic image stabilization, as may be achieved for example by herein described imaging systems, the embodiments can be based devices Multiaperturabbildungs-with respect to the electronic image stabilization without restrictions to individual. In the described embodiment, the imaging system has a common optical image stabilizer and a common electronic image stabilizer uses. By way of example, each module has two optical channels 16a and 16b or 16c and 16d, to image the full field of view with an object 71st Without limitation, the images 73a and 73b of the optical channels 16a and 16b in the associated image sensor regions as left figure 75a and Figures 73c and 73d of the optical channels 16c and 16d called a right picture of a stereoscope detection of the object 71st
FIG. 10a will display an error-free state in which the object is imaged on the image sensor portions 71 to obtain the figures 73a-d. The images 73a and 73b can be combined by the Multiaperturabbildungsvorrichtung to a left total image 77a, as by stitching. The images 73c and 73d may be used in a comparable manner by the combined Multiaperturabbildungsvorrichtung to a right overall image 77b, so that by the two full frames 75a and 75b stereoscopic information of the object 71 with respect to determined.
Fig. 10b now shows the case of Fig. 10a, in which a relative movement of the imaging system relative to the object 71 results in a direction shown by the object 71 'altered relative position of the object 71 relative to the imaging system. This may be, for example. A movement of the object 71 and / or be a shake of the imaging system. The relative movement now carries neglecting Bildkor-corrections to a change in image position of the image of the object 71 in the image sensor areas, which is shown by the dotted lines of Figures 73'ad.
The aim is now a obtaining images 77a and 77b, shown in Fig. 10a, so error compensated images. The aim is to compensate for the camera shake, so optimal image stabilization. In this consideration variations are not taken into account in the optics of the optical channels.
Fig. 10c shows the basis for the optical image stabilizer in the images on the unchanged assumption that a pure optical image stabilization optimum of all optical channels, the identical optical parameters comprise therefore have an identical focal length, lead to an optimal image stabilization. The displacement of the object 71 is represented by an arrow 79, the positive and negative in direction 28, device 32 has. By generating the relative motion between the image sensor, the array and the beam deflection by the optical image stabilizer is achieved that the pictures 73'ad and thus the overall images are shifted 77a and 77b along opposite directions 82a-d and 84a-b, wherein in the operating case effecting both the displacement of the object shown in Fig. 10b and the compensation Fig. 10c as promptly as possible, not to give rise only to the illustrated offset. The represented by arrows 84a-d and 77a-b are directions of the arrow 79 opposite in the space disposed, for example. At prominent points in the respective partial image, such as an eye of the mouth, which for example. Edges in the image means.
In Fig. 10d partial images obtained are now "represented 73 ad according to the optical image stabilization and taking into account actual deviations in the optical properties. The optical image stabilizer is, for example, carried out so that the image 73a is optimally corrected, that is, the optical image stabilized image 73 "a corresponds to the error-free image 73a, at least within a tolerance range, which indicates the capabilities of the optical image stabilizer.
Due to the variations in the optical properties of the image stabilization in the optical channel 16a now acts in the channels 16b-d different from, that is, the deviations in the optical characteristics cause example., That the arrows 82a-d, that of the displacement pictures indicating based on the optical stabilization, their length / or direction, and may be different.
This manifests itself in the assembled images 77 noticeable that from the corrected images 73 "a and 73" b, 73 "c and 73" d are formed. The divergence in the back shift by the optical image stabilization leads to a disintegration of the partial images, which may cause the stitching error. This is, for example, "c and 73" shown 73d in connection with the overall image 77b, or by that of the partial image 73 by the separated partial images "a stabilized properly spaced sub-image 73" b in the composite image 77a. In other words, there are errors in image composition, since an incompletely compensated image situation exists in all channels.
FIG. 10e shows the pictures of the channels 16b-c which is now opposite the Referenzka-nal 16a carried out optical image stabilization, which is indicated by the images 73 " 'b ~ d. By electronic image stabilization in the channels 16b-d away from the channel 16a whose deviations are compensated to the optical image stabilization in the optical channel 16a, at least partially, so that error-reduced or even error-free images 77 " 'a and 77"' may be obtained b, which may images chen entspre-77a and 77b. This means are obtained in part compensated image layers by optical image stabilization and compensated image layers by additional electronic image stabilization. the extent of the electronic image stabilization may be performed by the electronic image stabilization using the functional relationship between the optical channels 16a-d. Alternatively or additionally, the electronic image stabilizer, about the image stabilizer 41 may be formed in order to determine the amount of shift in the figures, for example by observation of a matching characteristic in two temporally different from one another or successive frames.
Fig. 1 1 is a schematic flow diagram of a method 1 100 for providing a Multiaperturabbildungsvorrichtung. In a step 1 1 10 providing is carried out of an image sensor. In a step 1120 is performed providing an array of optical channels, so that each optical channel comprises a total field of view to an image sensor area of the image sensor an optical system for imaging a partial field of view. In a step 1 130, a positioning is carried out of a beam deflecting device for deflecting an optical path of the optical channels. In a step 1 140, a positioning is carried out of an optical image stabilizer to stabilize the image along a first image axis by generating a first relative movement between the image sensor, the array and the beam deflecting device and to stabilize the image along a second image axis by generating a second relative movement between the image sensor, the array, and the beam deflection. In a step 1 150, a positioning is carried out of an electronic picture stabilizer for image stabilization of a first optical channel of the array along the first and the second image axis.
Embodiments described herein allow Multiaperturabbildungssysteme linear channel arrangement, ckungsrichtung ie single-line or multi-cell along a Zeilenerstre-, uniaxial with optical image stabilization using transiativer movement between the image sensor and imaging optics, as well as uniaxial rotative movement of a beam-deflecting mirror array.
Although embodiments previously described are described so that a number of four optical channels or a multiple thereof are disposed thereof Multiaperturabbildungsvorrichtungen according to other embodiments may include any number of optical channels, for example, at least two, at least three, at least four, at least ten or be arranged nälen Ka-higher number of optical.
Although embodiments described above are described as the optical image stabilizer 22 and the actuator 36 includes the actuator 42, according to other embodiments may be ausgebil-det, the actuators 36 and 42 as a common actuator. For example, a movement produced by the actuator by means of a force and / or path converter (gear) on the image sensor 12, the optical array 14 and / or the beam deflecting device 18 are guided to obtain a respective movement. Alternatively or additionally, one or more components can also be moved by a plurality of actuators, as tiaperturabbildungsvorrichtung Mul-for example, in connection with the described fortieth
The image sensor may, for example, as a complementary metal-oxide-semiconductor (comple-mentary metal-oxide-semiconductor - CMOS) or different therefrom technology be implemented. The optical channels of a respective arrays can be understood such that these define a range, in which a beam path that is guided to a respective image sensor area, changed optically. An assigned an image sensor optical path area may thus migrate through the array by the optical channel.
It has been further pointed out above that the optical paths or optical axes can be deflected starting from the beam deflecting device in mutually different directions. This can be obtained by the beam paths are steered during a deflection of the beam deflection and / or by the optics deviating from parallelism with one another. The optical paths and the optical axes may differ from a parallelism before or without a beam deflection. This circumstance is circumscribed so that in the following that the channels
a kind of pre-divergence can be provided. With this pre-divergence of the optical axes would be possible, for example, not class all facets inclinations of facets of the beam deflection different from each other, but that some groups of channels have, for example, the facets of the same inclination or be drawn to this. The latter can then be formed integrally or continuously merging into one another, as a kind of a facet, which is assigned to this group of adjacent rows in the direction of extension channels. The divergence of the optical axes of these channels could then be submitted by the divergence of these optical axes, as the channels is achieved by a lateral displacement between the optical centers of the lenses of the optical channels and image sensor areas. The pre-divergence could, for example, limited to a plane. The optical axes could, for example, before or without beam deflection in a common plane running, but divergent in this, and the facets merely cause only an additional divergence in the other transverse plane, ie all-extensive trend line parallel to and against each other, only different inclined to the aforementioned common plane of the optical axes, whereby in turn can have multiple facets same inclination here or group could be associated with shared by channels whose optical axes in pairs, for example, already in the aforementioned common plane of the optical axes before and differ without beam deflection , To simplify the optics can send a (pre-) allow divergence of the beam paths along a first (image) direction, and the beam deflecting device a divergence of the beam paths along a second (image) direction.
The above-mentioned may present a preliminary divergence can for example be achieved by making the optical centers of the lenses lie on a straight line along the line extending direction, while the centers of the image sensing areas of the projection of the optical centers along the normal of the plane of the image sensor regions on points on a line in the image sensor plane are anger assigns different, such as at points perpendicular dividual channel in-of the points on the said straight line in the image sensor plane along the line extending direction and / or along the direction perpendicular to both of the row direction of extension, as well as a representation of the image sensor normals. Alternatively, pre-divergence can be achieved by the centers of the image sensors lie on a straight line along the line extending direction, while the centers of the lenses of the projection of the optical centers of the image sensors along the normal of the plane of the optical centers of the lenses at points on a line in the optical centers plane anger assigns different, such as at points from the points
channel customization stretch direction Zeilener-on the said straight line in the optical centers plane along and / or along the direction perpendicular to both the Zeilenerstre-ckungsrichtung and the normal line of the optical centers level differ. It is preferred if aforesaid channel individual deviation of the respective projection-lent single runs in the row direction of extension, that is, the optical axes are located only in a common plane to be blown away with a pre divergence. Both optical centers are located and image sensor area centers then in each case on a straight line parallel to the line extending direction, but with different intermediate intervals. A lateral offset between lenses and image sensors in the vertical lateral Rich-tung to the line extension direction resulted in contrast to an increase of the height. A pure in-plane offset in rows extending direction does not change the height, but if necessary, it results in fewer facets and / or the facets have only a tilt on in an angular orientation, which simplifies the construction. Thus, for example, respectively adjacent optical channels in the common plane extending exhibit, in each case against one another squinting, provided therefore with a preliminary divergence optical axes. A facet can be arranged a group of optical channels with respect to inclined only in one direction and be parallel to the line extending direction.
Further, it could be provided that some optical channels associated with the same Teilge field of view, such as for the purpose of super-resolution, or to increase the resolution with which the corresponding sub-field is scanned by these channels. The optical channels within such a group then ran for example, before beam deflection parallel and would be deflected by a facet on a portion of the visual field. Advantageously, BE REDUCED pixel images of the image sensor of a channel of a group in intermediate positions between images of the pixels of the image sensor of another channel of this group.
It would be conceivable, for example, without Super Resolution purposes, but only to stereoscopy purposes in which a group covering directly Benach-disclosed channels in rows extending direction with its part of fields of view the overall field of view fully a design, and that a further group in turn, completely cover the entire field of each of immediately adjacent channels.
Thus, the above embodiments can be in the form of a ultiaperturabbildungsvorrich Maintenance and / or implement one such Multiaperturabbildungsvorrichtung comprehensive imaging system, with one-line channel arrangement, each
Channel transmits a part of the visual field of a total field of view and the partial facial fields partly overlap. A composition with more such Multiaperturabbildungsvor-directions for stereo Trio, Quattro, etc. Constructions for 3D imaging is possible. The plurality of modules can be designed as a continuous line. The continuous line could use identical actuators and a common beam deflection. One or more may be present in the beam path reinforcing substrates can check out the entire line that a stereo - can form, Trio, Quattro construction, extend. It can be used the super resolution method, wherein a plurality of channels, the same partial image areas represent. The optical axes can already run without divergent beam bending so that fewer facets on the beam deflecting unit are needed. The facets then have only one angle component advantageously. The image sensor may be one-piece, only a coherent matrix of pixels or more have broken. The image sensor may be composed of many sub-sensors, for example, on a printed circuit board are juxtaposed. An autofocus drive can be performed so that the beam deflection element is moved synchronously with the optics or is dormant.
