[0020] <1. First Embodiment
"Configuration example of appearance of display control device"
Fig. 1 is a perspective view which illustrates a configuration example of an ap
pearance of a display control device 100 according to the first embodiment of the
present technology. In Fig. 1, "a" illustrates an appearance of one surface side of the
display control device 100 (that is, surface on which input-output unit 150 is provided).
In addition, "b" of Fig.l illustrates an appearance of the other surface side of the
display control device 100 (that is, surface on which lens 121 is provided).
[0021] The display control device 100 includes first to fifth buttons 111 to 115, speakers 101
and 102, the lens 121, and the input-output unit 150. For example, the display control
device 100 is realized by a radio communication device which is able to display
various images (for example, a mobile phone, or a smart phone including call and data
communication functions). In addition, it is also possible to provide other operation
members in the display control device 100, however, figures and descriptions thereof
will be omitted.
[0022] The first to fifth buttons 111 to 115 are operation members for performing each
operation in the display control device 100.
[0023] The speakers 101 and 102 are speakers which output various pieces of sound in
formation. For example, the speaker 101 is a speaker which is used when making a
call, and the speaker 102 is a speaker which is used when reproducing contents, or the
like.
[0024] The lens 121 is a lens which condenses light from a photographic subject.
[0025] The input-output unit 150 is a unit which displays various images, and receives an
operation input from a user based on a detection state of an object which approaches,
or comes into contact with the display surface. In addition, the input-output unit 150 is
also referred to as a touch screen, or a touch panel.
[0026] "Functional configuration example of display control device"
Fig. 2 is a block diagram which illustrates a functional configuration example of the
display control device 100 according to the first embodiment of the present
technology.
[0027] The display control device 100 includes an operation reception unit 110, an imaging
unit 120, a recording medium control unit 130, a recording medium 140, the inputoutput
unit 150, an input control unit 160, a control unit 170, a size information
maintaining unit 171, and a display control unit 180. In addition, regarding each configuration
relating to a radio communication in the display control device 100, figures
and descriptions thereof will be omitted.
[0028] The operation reception unit 110 is an operation reception unit which receives an
operation performed by a user, and outputs a control signal (operation signal) corre
sponding to a received operation content to the control unit 170. The operation
reception unit 110 corresponds to the first to fifth buttons 111 to 115 in Fig. 1.
[0029] The imaging unit 120 includes an imaging element which converts light from a pho
tographic subject which is input through the lens (lens 121 illustrated in "b" of Fig. 1),
and an image signal processing unit which generates an imaged image (image data) by
processing an output signal of the imaging element (imaging signal). That is, in the
imaging unit 120, an optical image of the photographic subject which is input through
the lens is formed on the imaging surface of the imaging element, the imaging element
performs an imaging operation in this state, and the image signal processing unit
performs signal processing with respect to the imaging signal, thereby generating an
imaged image. A generation of the imaged image is performed based on start in
struction information of the imaging operation which is output from the operation
reception unit 110, or the reception unit 151. In addition, the generated imaged image
is supplied to the recording medium control unit 130, and the display control unit 180.
[0030] The recording medium control unit 130 is a unit which performs a control of
recording with respect to the recording medium 140, or reading from the recording
medium 140, based on a control of the control unit 170. For example, the recording
medium control unit 130 causes the recording medium 140 to record the imaged image
(image data) which is output from the imaging unit 120 as still image content (still
image file). In addition, for example, the recording medium control unit 130 causes the
recording medium 140 to record animation content (animation file) in which the
imaged image (image data) which is output from the imaging unit 120 and sound data
which is output from a sound signal processing unit (not shown) are correlated with
each other. In addition, for example, the recording medium control unit 130 reads out
the animation content which is stored in the recording medium 140, and outputs the
image data which is included in the animation content to the display control unit 180.
In addition, the sound data which is included in the animation data is output from the
speaker 102 (illustrated in "b" of Fig. 1).
[0031] The recording medium 140 is a medium which stores various pieces of information
(still image content, or animation content) based on the control of the recording
medium control unit 130. In addition, the recording medium 140 supplies the stored
various pieces of information to the recording medium control unit 130.
[0032] The input-output unit 150 includes a reception unit 151 and a display unit 152. For
example, it is possible to use an electrostatic-type (electrostatic capacity type) touch
panel which detects contact or the approaching of a conductive object (for example, a
human finger) based on a change in an electrostatic capacitance as the reception unit
151. In addition, for example, it is possible to use a display panel such as an LCD
(Liquid Crystal Display), an organic EL (Electro Luminescence) panel as the display
unit 152. In addition, the input-output unit 150 is configured, for example, by
overlapping transparent touch panels with each other on the display surface of the
display panel.
[0033] The input-output unit 150 displays various images on the display unit 152 based on a
control of the display control unit 180, and receives an operation input from a user
based on a detection state of an object which approaches, or comes into contact with
the display surface (display surface of display unit 152) of the input-output unit 150 by
the reception unit 151. In addition, the reception unit 151 outputs a control signal cor
responding to the received operation input to the input control unit 160.
[0034] The reception unit 151 is a unit which receives an operation input of an object (for
example, user's finger) which approaches, or comes into contact with the display
surface of the input-output unit 150, based on the detection state of the object. For
example, the reception unit 151 includes a plurality of electrostatic sensors which are
arranged in a lattice shape. The electrostatic sensors are sensors which increase an
electrostatic capacitance when an object (conductive object (for example, human hand,
or finger)) approaches, or comes into contact with the display surface of the inputoutput
unit 150. In addition, the reception unit 151 outputs information (information of
the electrostatic sensor) including a value of the electrostatic capacitance of the elec
trostatic sensor, and a position of the electrostatic sensor on the operating surface of
the reception unit 151 to the input control unit 160 when the electrostatic capacitance
of the electrostatic sensor is changed. In addition, hereinafter, only a detection example
of an object which comes into contact with the display surface of the input-output unit
150 is described, however, it is possible to similarly apply to a detection of an object
which approaches the display surface of the input-output unit 150. In addition, the
reception unit 151 is a detection unit which detects an object which comes into contact
with the display surface on which an operation target for performing the operation
input is displayed. That is, the reception unit 151 is an example of the detection unit. In
addition, the operation target is, for example, displayed on the input-output unit 150
like setting operation images 331 to 334 illustrated in Fig. 3. For example, the
operation target is data for performing the operation input, or an object (for example,
GUI (Graphical User Interface) parts).
[0035] The display unit 152 is a display panel which displays each image based on the
control of the display control unit 180. In addition, a display example in the display
unit 152 will be shown in Figs. 3 to 9, or the like.
[0036] The input control unit 160 is a unit which performs a control relating to an operation
input by a user (for example, touch operation (tap operation)) which is received by the
reception unit 151. For example, the input control unit 160 detects a range (contract
range) of the display surface of the input-output unit 150 on which a user's finger
touched based on the information of the electrostatic sensor which is output from the
reception unit 151, and converts the contact range to a coordinate, based on a co
ordinate axis corresponding to the display surface. In addition, the input control unit
160 calculates a shape of the contact range based on the converted coordinate, and
calculates a coordinate of the center of gravity in the shape. In addition, the input
control unit 160 calculates the calculated coordinate of the center of gravity as a co
ordinate of a position (contact position) which a user's finger touched. In addition, the
input control unit 160 outputs operation information relating to the shape of the
calculated contract range, and the coordinate of the contact position to the control unit
170. The control unit 170 recognizes the operation input of the user on the display
surface of the input-output unit 150 based on the operation information (shape of
contact range, coordinate of contact position, or the like) which is output from the
input control unit 160.
[0037] The control unit 170 is a unit which controls each unit of the display control device
100 based on the operation signal from the operation reception unit 110, and the
operation information (shape of contact range, coordinate of contact position, or the
like) from the input control unit 160. In addition, the control unit 170 maintains a
contact size (detected size) of the contact operation by the user which is detected on
the display surface of the input-output unit 150 in the size information maintaining unit
171.
[0038] In addition, for example, the control unit 170 performs a control which changes
operation contents of an operation target based on a contact size (detected size) of an
object (for example, user's finger) on the display surface of the input-output unit 150.
That is, the control unit 170 changes the operation contents of at least a part of the
plurality of operation targets based on the contact size (detected size) of the object on
the display surface of the input-output unit 150. For example, the control unit 170
changes the operation contents of the operation targets by disabling the operation input
of the operation targets based on the contact size (detected size) of an object on the
display surface of the input-output unit 150.
[0039] In addition, for example, the control unit 170 changes the operation content based on
a comparison result between the contact size (detected size) of the object on the display
surface of the input-output unit 150 and the size of the operation target on the display
surface of the input-output unit 150. Specifically, the control unit 170 enables the
operation input of the operation target based on the contact size (detected size) of the
object on the display surface of the input-output unit 150, and when the size of the
operation target on the display surface of the input-output unit 150 is large. On the
other hand, the control unit 170 disables the operation input of the operation target
when the size of the operation target on the display surface of the input-output unit 150
is small. In addition, according to the first embodiment of the present technology, the
operation target of which the operation input is disabled is referred to as a simple
operation target, and the operation target of which the operation input is enabled is
referred to as a detailed operation target.
[0040] The size information maintaining unit 171 is a unit which maintains the reference
size which is used when determining the simple operation target and detailed operation
target, and the contact size (detected size), and supplies each maintained size in
formation to the control unit 170.
[0041] Here, the reference size is a value (specified value) which denotes the size of the
stylus which is used when performing an operation, or a finger of a standard user, and
is preset. In addition, the contact size (detected size) is a value based on the value
which is detected in the reception unit 151 (value denoting size of stylus used when
performing operation by user, or size of finger of user).
[0042] For example, the control unit 170 causes the size information maintaining unit 171 to
sequentially maintain the value which is detected in the reception unit 151 (for
example, the area in which user's finger touched (contact area)). In addition, the control
unit 170 calculates a mean value of the contact area which is maintained in the size in
formation maintaining unit 171, and causes the size information maintaining unit 171
to maintain the mean value as a contact size (detected size). That is, the contact size
(detected size) is a mean value of input values which are actually input. However,
since it is also considered that a child may use the device after an adult, it is preferable
to use the mean value per unit hour as the contact size (detected size).
[0043] The display control unit 180 is a unit which causes each image to be output to the
display unit 152 based on the control of the control unit 170. For example, the display
control unit 180 causes a set screen for performing various setting when performing an
imaging operation (for example, menu screen 300 in Fig. 3), or an imaged image
which is output from the imaging unit 120 (so-called through image) to be displayed
on the display unit 152. In addition, for example, the display control unit 180 causes
content which is stored in the recording medium 140 (for example, still image content,
or animation content) to be displayed on the display unit 152.
[0044] "Display example of menu screen"
Fig. 3 is a diagram which illustrates an example of a display screen (menu screen
300) which is displayed on the input-output unit 150 according to the first embodiment
of the present technology. In addition, in Figs. 3 to 9, or the like, displays of the first to
fifth buttons 111 to 115, the speaker 101, or the like are omitted.
[0045] The menu screen 300 is a screen in which the operation targets are grouped
according to the types thereof in order to look around the whole menu. That is, the
grouped operation targets are divided into nine regions in a unit of group in a state of
being compactedly displayed (overlook state), and are displayed on one screen (menu
screen 300). That is, operation targets which are look similar (for example, items
relating to the same function) belong to each group. In addition, the menu screen 300
which is divided into nine regions is an example, and it is also preferable to appro
priately change the number of regions according to each operation target as a display
target.
[0046] Specifically, an imaging mode setting region 310, a flash system setting region 320, a
white balance system setting region 330, a reproducing setting region 340, and a
diaphragm adjusting region 350 are displayed on the menu screen 300. In addition, a
face detection system setting region 360, a guide display system setting region 370, an
imaged image size system setting region 380, and an animation system setting region
390 are displayed on the menu screen 300.
[0047] The imaging mode setting region 310 is a region in which operation targets which are
used when setting the imaging mode (for example, still image imaging mode, and
animation imaging mode) are displayed.
[0048] The flash system setting region 320 is a region in which operation targets which are
used when performing various setting relating to a flash are displayed.
[0049] The white balance system setting region 330 is a region in which operation targets
which are used when performing various setting relating to a white balance are
displayed.
[0050] The reproducing setting region 340 is a region in which operation targets for setting
reproducing modes, and operation targets which are used when reproducing image
content are displayed.
[0051] The diaphragm adjusting region 350 is a region in which operation targets which are
used when adjusting a diaphragm are displayed.
[0052] The face detection system setting region 360 is a region in which operation targets
which are used when performing various setting relating to face detection are
displayed.
[0053] The guide display system setting region 370 is a region in which operation targets
which are used when performing various setting relating to a guide function (help
function) are displayed.
[0054] The imaged image size system setting region 380 is a region in which operation
targets which are used when performing various settings relating to a size of an imaged
image as a recording target are displayed. For example, an aspect ratio of an imaged
image (still image) as a recording target (for example, 4:3 or 16:9), or an image size of
an imaged image (still image) as a recording target (STD, or WIDE) can be set.
[0055] The animation system setting region 390 is a region in which operation targets which
are used when performing various settings relating to an animation are displayed.
[0056] In addition, the operation targets, regions or the like which are displayed on the menu
screen 300 are examples, and it is also preferable to appropriately perform changing
according to the set mode, the imaging operation state, or the like.
[0057] In addition, the operation targets (items) on the menu screen 300 or the like are
operation region images (operation mark) which are used when performing the
operation input by a user, and for example, the operation targets can be operated using
a contact operation by a user (for example, touch operation, and tracing operation
(dragging operation)). However, on the menu screen 300, only an operation target
(detailed operation target) corresponding to a contact size (detected size) in the contact
operation by a user, and other operation targets (simple operation target) are disabled
from being operated. For this reason, in order to operate the operation targets which are
disabled from being operated (simple operation target), it is necessary to perform a
selecting operation (touch operation) of selecting a region in which the operation
targets are displayed (310, 390), and display a display screen in which the region is
displayed by being enlarged (zoom state). The display examples are illustrated in Figs.
6, 8, and 9.
[0058] For example, a case is assumed in which a touch operation is performed using a
user's finger 10 in the input-output unit 150 in a state where the menu screen 300 is
displayed on the input-output unit 150. In this case, the control unit 170 specifies at
which position of the menu screen 300 the touch operation has been performed. That
is, the control unit 170 specifies the position on the display surface of the input-output
unit 150 which a user's finger touched (contact position) based on the operation input
which is output from the input control unit 160. In addition, the control unit 170
performs a process corresponding to the detailed operation target when the contact
position is included in the detailed operation target. On the other hand, the control unit
170 performs a control in which a region to which the contact position is included
(310, 390) is enlarged, and is displayed on the input-output unit 150 when the
contact position is not included in the detailed operation target (including case in
which the contact position is included in the simple operation target). For example, an
example of an enlarged display in a case where the touch operation using the user's
finger 10 is performed in the white balance system setting region 330 is illustrated in
Fig. 6.
[0059] Here, it is possible to smoothly perform a movement, or grasping between data items,
by performing switching or expanded, or compacted displaying of a virtual space to a
view point position displaying,. In addition, a user is able to perform an easy operation
since it is possible for a user to pay attention to an operation target which is in the
user's mind by performing an expanded displaying.
[0060] However, for example, it is assumed that there is also a case where an operation
target which is different from the operation target intended by a user is touched, or a
case where two or more operation targets are touched since each operation target is
displayed compactedly when the menu screen 300 is displayed. In addition, the case
where two or more operation targets are touched against the will of the user is referred
to as a conflict.
[0061] Therefore, the operation is performed such that the size of the stylus, or a finger of a
user (reference size) on the side which performs an operation is uniquely defined in
advance, and a display state in which the operation is disabled, or a region in which the
operation is disabled is statically defined according to the display state. In this manner,
it is possible to prevent occurrences of the conflict, or an erroneous operation when
operating the compactedly displayed operation target. However, when a difference
between the defined value (reference size) and the size of the stylus, or the finger of
the user is large, a case is also assumed in which the operation target is erroneously
operated.
[0062] In particular, in a virtual space in which the display magnification can be expanded
or compacted without steps, an operation target which is viewed as an operation target
which can be operated in practice is limited according to a relatively large specified
value (reference value) when it is different from the size of the specified value
(reference value), and becomes difficult to be operated. On the other hand, it is also
assumed that the operation target becomes the conflict, or is erroneously operated
according to a relatively small specified value (reference value).
[0063] Therefore, according to the first embodiment of the present technology, the detailed
operation target, and the simple operation target are determined using the reference
size and the detected size together.
[0064] "Example of determination of detailed operation target and simple operation target"
Fig. 4 is a diagram which illustrates a relationship between the operation target which
is displayed on the input-output unit 150 and the reference size which is maintained in
the size information maintaining unit 171 according to the first embodiment of the
present technology.
[0065] In Fig. 4, "a" illustrates an example of a relationship between a reference size 200
and an operation target which is displayed by being enlarged. In addition, "b" of Fig.4
illustrates an example of relationship between the reference size 200 and an operation
target which is displayed by being compacted. In addition, in "a" and "b" of Fig.4,
setting operation images (operation targets) 331 to 334 in the white balance system
setting region 330 in Fig. 3 are exemplified.
[0066] In addition, as described above, it is possible to perform the expansion and con
traction by a user's operation, in each region included in the menu screen 300, and in
"a" and "b" of Fig.4, the white balance system setting region 330 having a different
display magnification is assumed to be described.
[0067] The setting operation images 331 to 334 are displayed in the white balance system
setting region 330. The setting operation images 331 to 334 are operation images
which are used when adjusting the white balance at the time of setting the imaging
mode. For example, the white balance can be adjusted by the contact operation of the
setting operation images 331 to 334.
[0068] In addition, a size which is used as a comparison target (reference size, detected size
(contact size), and size of operation target) according to the embodiment of the present
technology means an area on the display surface of the input-output unit 150.
However, it is also preferable to use a value which is specified by a shape or the like
thereof (for example, an area which is specified by rectangle surrounding operation
target).
[0069] Here, as shown in "a" of Fig.4, a case is assumed in which the reference size 200 is
smaller than the sizes of the setting operation images 331 to 334. In this case, it is
highly possible that an operation target which is intended by a user (setting operation
images 331 to 334) is able to be operated in detail. For this reason, the control unit 170
determines the operation target which is larger than the reference size 200 as the
detailed operation target. In this manner, the operation target which is determined to be
the detailed operation target can be operated using the user's contact operation on the
display surface of the input-output unit 150.
[0070] In addition, as shown in "b" of Fig.4, a case is assumed in which the reference size
200 is larger than the size of the setting operation images 331 to 334. In this case, there
is a concern that the erroneous operation in which an operation target (for example,
setting operation image 333) different from the operation target which is intended by a
user (for example, setting operation image 331) is erroneously operated, or the conflict
may occur. For this reason, the control unit 170 determines an operation target of
which the size is smaller than the reference size 200 as the simple operation target. In
this manner, the operation using a user's contact operation on the display surface of the
input-output unit 150 is disabled with respect to the operation target which is de
termined to be the simple operation target.
[0071] Here, a relationship between the reference size which is maintained in the size in
formation maintaining unit 171 and the detected size (contact size) will be described.
[0072] For example, a case is assumed in which the detected size is relatively smaller than
the reference size. In this case, it is assumed that even if it is an operation target of a
relatively small size, the operation target can be operated using an operation object (for
example, finger) in many cases. That is, even if it is a simple operation target which is
determined based on the reference size, there is a possibility that the simple operation
target can be operated in detail according to the will of a user. For this reason, the
control unit 170 newly determines the simple operation target of which the size is
larger than the detected size as the detailed operation target. In this manner, it is
possible to perform the operation using the user's contact operation on the display
surface of the input-output unit 150 with respect to the operation target which is newly
determined to be the detailed operation target.
[0073] On the other hand, for example, a case is assumed in which the detected size is
relatively larger than the reference size. In this case, it is assumed that even if it is an
operation target of a relatively large size, the operation target cannot be operated using
the operation object (for example, finger) in many cases. That is, there is a concern that
the erroneous operation in which an operation target which is different from the
operation target (for example, setting operation image 333) intended by a user (for
example, setting operation image 331) is erroneously operated, or the conflict may
occur. For this reason, the control unit 170 newly determines a detailed operation
target (detailed operation target which is determined based on reference size) of which
the size is smaller than the detected size as the simple operation target. In this manner,
the operation using the user's contact operation on the display surface of the inputoutput
unit 150 is disabled with respect to the operation target which is newly de
termined to be the simple operation target.
[0074] In this manner, a detailed operation target and simple operation target are newly de
termined based on the detected size with respect to the detailed operation target and
simple operation target which are determined based on the reference size. That is, it is
possible to perform an appropriate determination (determination on detailed operation
target and simple operation target) according to a size (detected size) of an operation
object (for example, finger) which is operated in practice. In this manner, it is possible
to prevent the occurrences of erroneous operation and conflict.
[0075] "Display example of operation target"
Figs. 5 to 9 are diagrams which illustrate examples of display screens which are
displayed on the input-output unit 150 according to the first embodiment of the present
technology. In Figs. 5 to 9, examples of relationships between the size of the operation
object (for example, finger 10, hand 20) and the detailed operation target, and the
simple operation target are simplified and illustrated.
[0076] Fig. 5 illustrates the menu screen 300 a case where a contact operation is performed
using a finger 10 as the operation object. In addition, the menu screen 300 illustrated in
Fig. 5 is the same as that in Fig. 3. However, among the operation targets which are
displayed on the menu screen 300 (for example, setting operation screens 331 to 334),
only the operation targets which are surrounded by dotted lined-rectangles 401 and 402
are set to the detailed operation target. For this reason, in the menu screen 300, it is
possible to perform only the contact operation of the operation of selecting the nine
regions (310, 390), and the operation of the detailed operation targets which are
surrounded with the dotted lined-rectangles 401 and 402.
[0077] In addition, it is also preferable to display the detailed operation target and the simple
operation target using a different display form so as to be easily distinguished from
each other by a user. For example, it is possible to highlight the detailed operation
target (displaying detailed operation target brighter than simple operation target). In
addition, it is also preferable to display the detailed operation target in blue when the
menu screen 300 is a display screen which is based on white. In addition, it is also
preferable to display the detailed operation target such that the detailed operation target
is minute, and is repeatedly displayed by being expanded, or compacted (For example,
detailed operation target is displayed in a feeling of moving lightly).
[0078] Here, it is possible to operate the operation targets other than the detailed operation
targets (simple operation target (for example, setting operation images 331 to 334))
which are surrounded with the dotted lined-rectangles 401 and 402 by displaying each
region to be enlarged.
[0079] For example, since the setting operation images (simple operation targets) 331 to 334
which are displayed in the white balance system setting region 330 are operated, an
example in which the white balance system setting region 330 is displayed by being
enlarged is illustrated in Fig. 6.
[0080] A menu screen 410 which is displayed when a touch operation with respect to the
white balance system setting region 330 is performed by the user on the menu screen
300 shown in Fig. 5 is illustrated in Fig. 6. That is, the menu screen 410 is a screen in
which the white balance system setting region 330 is enlarged. In this manner, one
screen (menu screen 410) is displayed in a unit of group in a state where the grouped
operation targets are displayed by being enlarged (zoom state).
[0081] In the menu screen 410, the setting operation images (detailed operation targets) 331
to 334 are displayed. In addition, the setting operation images (detailed operation
targets) 331 to 334 are the same as those in Fig. 4.
[0082] As shown in Figs. 5 and 6, the menu screen in a compacted display state (overlook
state) in which the operation targets are displayed by being compacted, and the menu
screen in an enlarged display state (zoom state) in which the operation targets are
displayed by being enlarged are displayed on the display control device 100. In
addition, the display on these menu screens are switched by a user's operation (for
example, contact operation on display surface of input-output unit 150, or pressing
operation of first to third buttons 111 to 113).
[0083] Here, it is assumed that all of the setting operation images 331 to 334 which are
displayed on the menu screen 410 are the detailed operation targets (illustrated by
being surrounded by dotted lined-rectangles 411 to 414). For this reason, in the menu
screen 410, it is possible to perform the contact operation with respect to all of the
setting operation images 331 to 334.
[0084] Here, for example, it is assumed that the contact operation is performed by the
operation object of which the detected size is larger than the size of the setting
operation images 331 to 334 in the menu screen 410. For example, as illustrated in Fig.
7, it is also assumed that the contact operation is performed using a hand 20 in a state
of a rock as the operation object. Therefore, in Figs. 7 to 9, examples of a relationship
between the detailed operation target and the simple operation target in a case where
the contact operation is performed by the operation object of which the detected size is
relatively large.
[0085] Fig. 7 illustrates the menu screen 300 which is displayed when the contact operation
is performed using the back of the hand 20 in the state of a rock as the operation
object. For example, it is assumed that the contact operation is performed in a state
where the hand 20 grasps something. In addition, the menu screen 300 illustrated in
Fig. 7 is the same as that in Fig. 3.
[0086] However, it is assumed that all of the operation targets displayed on the menu screen
300 (for example, setting operation images 331 to 334) are the simple operation
targets. For this reason, it is possible to perform only the selecting operation of the nine
region (310, 390) on the menu screen 300 using the contact operation.
[0087] For this reason, it is necessary to display each region by enlarging the region in order
to perform the contact operation with respect to each operation target (simple operation
target, (for example, setting operation images 331 to 334)). For example, in order to
operate the setting operation images (simple operation targets) 331 to 334 which are
displayed in the white balance system setting region 330, an example in which the
white balance system setting region 330 is displayed by being enlarged is illustrated in
Fig. 8.
[0088] Fig. 8 illustrates the menu screen 410 which is displayed when the touch operation
with respect to the white balance system setting region 330 is made by a user on the
menu screen 300 shown in Fig. 7. In addition, the menu screen 410 illustrated in Fig. 8
is the same as that in Fig. 6.
[0089] However, it is different in that all of the operation targets which are displayed on the
menu screen 410 (setting operation images 331 to 334) are the simple operation
targets.
[0090] For this reason, it is necessary to display each region by further enlarging the region
in order to perform the contact operation with respect to each operation target (setting
operation images 331 to 334). For example, in order to operate the setting operation
image (simple operation target) 331, an example in which the setting operation image
(simple operation target) 331 is displayed by being enlarged is illustrated in Fig. 9.
[0091] In Fig. 9, a menu screen 420 which is displayed when the operation of enlarging the
setting operation image 331 is performed by a user (for example, touch operation in
vicinity of setting operation image 331) on the menu screen 410 shown in Fig. 8 is i l
lustrated. That is, the menu screen 420 is a screen in which the setting operation image
331 is enlarged.
[0092] Here, it is assumed that the setting operation image 331 which is displayed on the
menu screen 420 is the detailed operation target (illustrated by being surrounded by
dotted lined-rectangle 421). For this reason, it is possible to perform the contact
operation of the setting operation image 331 on the menu screen 420.
[0093] In this manner, it is necessary to display the operation target by enlarging the target
to a size of the detected size when the contact operation is performed by an operation
target of which the detected size is a relatively large.
[0094] "Operation example of display control device"
Figs. 10 and 11 are flowcharts which illustrate one example of a processing order of
a display control processing order by the display control device 100 according to the
first embodiment of the present technology.
[0095] Initially, the control unit 170 determines whether or not a display instructing
operation of the menu screen has been performed (step S901), and performs
monitoring continuously when the display instructing operation of the menu screen is
not performed. When the display instructing operation of the menu screen has been
performed (step S901), the control unit 170 determines the detailed operation target
and simple operation target based on the reference size which is maintained in the size
information maintaining unit 171 (step S902). That is, each operation target as the
display target which is included in the menu screen is determined to be any of the
detailed operation target and simple operation target (step S902).
[0096] Subsequently, the display control unit 180 displays the menu screen on the display
unit 152 based on an instruction of the control unit 170 (step S903). For example, the
menu screen 300 illustrated in Fig. 3 is displayed. Here, among the operation targets
which are displayed on the menu screen, the detailed operation target can be operated,
however, in contrast to this, the simple operation target cannot be operated.
[0097] Subsequently, the control unit 170 determines whether or not the operation has been
performed by a user (step S904), and continues monitoring when the operation by a
user has not been performed. On the other hand, when the operation by a user has been
performed (step S904), the control unit 170 determines whether or not the operation is
an operation of completing a display of the menu screen (step S905). In addition, when
the operation is the operation of completing the display of the menu screen (step
S905), the operation of display control processing is completed.
[0098] When the operation is the operation of completing the display of the menu screen
(step S905), the control unit 170 determines whether or not the contact operation on
the display surface of the input-output unit 150 has been performed (step S906), and
when the contact operation has not been performed, the process proceeds to step S908.
When the contact operation on the display surface of the input-output unit 150 has
been performed (step S906), the control unit 170 obtains a size of the operation object
(for example, finger) (for example, contact area) based on the contact operation, and
causes the size information maintaining unit 171 to maintain the size information (step
S907). In this case, a mean value of the past size (for example, contact area) is
calculated, and the mean value is maintained in the size information maintaining unit
171 as the detected size (contact size). In addition, step S906 is an example of a
detecting order.
[0099] Subsequently, the control unit 170 determines whether or not the operation is a
changing operation of a display magnification (step S908). In addition, when the
operation is the changing operation of the display magnification (step S908), the
control unit 170 determines the detailed operation target and the simple operation
target relating to the display magnification after changing based on the reference size
which is maintained in the size information maintaining unit 171 (step S909). That is,
the detailed operation target and simple operation target are newly determined with
respect to each operation target included in the menu screen having the display magni
fication after changing (step S909). Subsequently, the display control unit 180 causes
the display unit 152 to display the menu screen using the changed display magni
fication (step S910) based on an instruction of the control unit 170, and the process
returns to step S904.
[0100] In addition, when the operation is not the changing operation of the display magni
fication (step S908), the control unit 170 performs processing according to the
operation (step S911). Subsequently, the control unit 170 determines whether or not
the detected size is maintained in the size information maintaining unit 171 (step
5912) , and the process returns to step S904 when the detected size is not maintained in
the size information maintaining unit 171.
[0101] When the detected size is maintained in the size information maintaining unit 171
(step S913), the control unit 170 compares the reference size which is maintained in
the size information maintaining unit 171 and the detected size with each other (step
5913) . In addition, when the detected size is smaller than the reference size by a prede
termined value or more (step S913), the control unit 170 determines an operation target
which is set to be operated by the detected size as the detailed operation target, among
the simple operation targets included in the menu screen (step S914). That is, the
operation target which is set to be operated by the detected size among the simple
operation targets included in the menu screen which is displayed on the display unit
152 is changed to the detailed operation target from the simple operation target (step
5914) .
[0102] In addition, when the detected size is smaller than the reference size by a prede
termined value or more (step S913), the control unit 170 determines whether or not the
detected size is larger than the reference size by the predetermined value or more (step
5915) . When the detected size is larger than the reference size by the predetermined
value or more (step S915), the control unit 170 determines the operation target which
is difficult to operate (cannot be operated) due to the detected size, among the detailed
operation targets included in the menu screen as the simple operation target (step
5916) . That is, among the detailed operation targets which are included in the menu
screen displayed on the display unit 152, the operation target which is difficult to
operate due to the detected size is changed to the simple operation target from the
detailed operation target (step S916).
[0103] In addition, when the detected size is not larger than the reference size by the prede
termined value or more (for example, approximately the same as detected size and
reference size) (step S915), the process proceeds to step S904. In addition, steps S913
to S916 are examples of control orders.
[0104] In this manner, according to the first embodiment of the present technology, the size
of the stylus, or the finger which is used when performing the operation is measured,
and an operation target which is predicted to be difficult to be operated according to
the display state is dynamically limited to the simple operation target from the detailed
operation target. In addition, even when the size of the operation target to be operated
is different from the size which is specified by being assumed in advance (reference
size), or even when the enlarged and compacted display in a virtual space is changed to
any display magnification, it is possible to prevent the occurrence of the conflict, or
erroneous operation. That is, it is possible to prevent the occurrence of the conflict, or
erroneous operation in the virtual space in which the view point position is switched,
or the enlarged and compacted display is performed, by measuring the size of the
stylus, or the finger which is used when performing the operation, and dynamically r e
flecting it for a determining process of the operation target according to the display
state.
[0105] In addition, according to the first embodiment of the present technology, an example
in which a new determining process is performed using the detected size with respect
to the detailed operation target and simple operation target which are determined based
on the reference size is described. However, it is also preferable to determine the
detailed operation target and the simple operation target based only on the detected
size.
[0 106] "Other determination examples "
Hitherto, an example in which the detailed operation target and simple operation
target which are determined based on the size of the operation target on the display
screen, and a comparison result between the reference size and the detected size has
been described. However, for example, even when the size of the operation target on
the display screen is relatively small, the operation target is considered to be operated
when other operation targets are not present in the periphery thereof, or the like.
[0107] Therefore, an example in which other elements than the size of the operation target
on the display screen are used in determining is described.
[0108] Initially, a determination example in which the number of operation targets in the
display screen (or, in a region of a predetermined range) is set to a determination
element will be described. For example, when there is one operation target which is
present on the display screen (or in a region of the predetermined range), the operation
target is considered to be operated, even when the size of the operation target on the
display screen is remarkably smaller than the detected size. For this reason, when there
is one operation target which is present on the display screen (or in region of the prede
termined range), the operation target is determined to be the detailed operation target.
That is, even when the operation target is remarkably smaller than the detected size,
the operation target is determined to be the detailed operation target when there is
nothing in the periphery thereof.
[0109] In this manner, the control unit 170 enables the operation input of an operation target
when a predetermined condition is satisfied even when it is the operation target of
which the operation input is determined to be disabled based on the contact size of an
object on the display surface. In addition, a case where the predetermined condition is
satisfied is, for example, a case in which the number of the operation target and other
operation targets which is present in a predetermined region on the display surface is
less than a predetermined number (for example, 1).
[0110] Subsequently, a determination example in which a distance between the operation
targets on the display surface is set to a determination element will be described. For
example, a case is assumed in which a plurality of operation targets are present in the
display screen (or, in a region of a predetermined range). In this case, when the size of
each of the operation targets on the display screen (for example, length in direction in
which two operation targets are connected) is larger than the distance between two
operation targets by a predetermined value or more, these two operation targets are
considered to be difficult to operate (cannot be operated). For this reason, when the
size of each operation target on the display surface is larger than the distance between
the two operation targets by the predetermined value or more, the operation target is
determined to be the simple operation target.
[01 11] In this manner, the control unit 170 disables the operation input of the two operation
targets when the distance between the two operation targets among the plurality of
operation targets on the display surface is small based on the value which is specified
by the contact size of the object on the display surface.
[01 12] That is, since the occurrence of the erroneous operation in which an operation target
different from the operation target which is intended by a user is operated, or the
conflict is prevented, it is possible to determine the detailed operation target and the
simple operation target based on the interval of the operation targets, a positional rela
tionship thereof, and the number thereof.
[0113] <2. Second Embodiment
According to the first embodiment of the present technology, an example in which
the detailed operation target and the simple operation target are determined based on
the reference size and the detected size has been described. Here, when an operation
target of which the operation on the display surface is difficult is present, it is also
considered that a display magnification thereof is changed, and an operation of the
operation target is enabled.
[01 14] Therefore, according to a second embodiment of the present technology, an example
has been described in which the display magnification is changed (for example,
enlarging), and the operation of the operation target is enabled, when the operation
target of which the operation on the display surface is difficult is present. In addition, a
configuration of a display control device according to the second embodiment of the
present technology is approximately the same as the examples illustrated in Figs. 1 and
2, or the like. For this reason, regarding portions which are common to the first em
bodiment of the present technology, a part of descriptions thereof will be omitted.
[01 15] "Operation example of display control device"
Fig. 12 is a flowchart which illustrates an example of a processing order of a display
control processing by the display control device 100 according to the second em
bodiment of the present technology. In addition, a detected size as history information
is sequentially maintained in the size information maintaining unit 171. In addition,
regarding steps S921 and S922, descriptions thereof will be omitted since they have the
same processing order as those of steps S906 and S907 illustrated in Fig. 10.
[0116] A control unit 170 compares a detected size which is obtained this time to a detected
size in the past which is maintained in a size information maintaining unit 171, and de
termines whether or not these are different from each other by a predetermined value
or more (step S923). In addition, when the two detected sizes are in a range of the predetermined
value (step S923), the operation of the display control processing is
completed.
[01 17] When the two detected sizes are the predetermined value or more (step S923), the
control unit 170 determines whether or not an operation target of which the operation
is difficult (cannot be operated) due to the size which is detected this time is present
among the operation targets which are included in the menu screen (step S924). In
addition, when there is no operation target of which the operation is difficult (cannot
be operated) due to the size which is detected this time (step S924), the operation of
display control processing is completed.
[0118] In addition, when there is an operation target of which the operation is difficult
(cannot be operated) due to the size which is detected this time (step S924), the control
unit 170 calculates a display magnification in which the operation target of which the
operation is difficult (cannot be operated) can be operated using the detected size of
this time (step S925). That is, a display magnification in which all of operation targets
included in the menu screen become the detailed operation target is calculated. Sub
sequently, a display control unit 180 displays the menu screen with the calculated
display magnification on a display unit 152 based on an instruction of the control unit
170 (step S926). For example, the menu screen is displayed by being enlarged and
having a position at which the latest contact operation has been performed as the center
position.
[0119] In addition, it is also preferable to display a simple operation target which is
performed with a contact operation, and the vicinity thereof by enlarging, only when
the contact operation is performed by a user with respect to the simple operation target
which is displayed on the display unit 152.
[0120] In this manner, the control unit 170 performs a control for changing a display content
of an operation target based on the contact size of an object on the display surface.
Specifically, when there is an operation target of which the operation input is de
termined to be disabled based on the contact size of an object on the display surface,
the control unit 170 performs a control for displaying the operation target by enlarging
to a size by which the operation input of the operation target is enabled.
[0121] <3. Modification Example>
According to the first and second embodiments of the present technology, examples
in which detected sizes are obtained using the operation input in the middle of
operating the display control device 100 (contact operation on display surface of inputoutput
unit 150) has been described. Here, obtaining a detected size on a measurement
screen for measuring the detected size is also considered. Therefore, hereinafter, an
example of obtaining a detected size on the measurement screen will be described.
[0122] "Measurement example of detected size"
Fig. 13 is a diagram which illustrates an example of a display screen (detected size
measurement screen 500) which is displayed on an input-output unit 150 according to
the embodiments of the present technology, and the measurement result. In addition, a
measuring method illustrated in Fig. 13 can be realized, for example, by a method in
tegrated into a calibration procedure which is performed on a precision adjustment
screen of a general touch panel.
[0123] In Fig. 13, "a" illustrates the detected size measurement screen 500 for measuring a
detected size. A contact position image 501 and a tracing direction image 502 are
displayed on the detected size measurement screen 500. When measuring of a detected
size is performed on the detected size measurement screen 500, a user touches the
contact position image 501 with an object (for example, user's finger 50) which is used
when performing the operation input on the display surface of the input-output unit
150. Subsequently, the user moves the finger 50 along an arrow of the tracing direction
image 502 in a state where the finger 50 comes into contact with the display surface of
the input-output unit 150.
[0124] In this manner, it is possible to measure a contact size of the finger 50 (detected size)
when the user performs the contact operation of the finger 50, and the tracing operation
on the detected size measurement screen 500. In addition, in this example, an example
in which the contact size (detected size) of the finger 50 is measured by performing the
contact operation and the tracing operation is illustrated, however, it is also preferable
to measure the contact size (detected size) of the finger 50 by performing any one of
the operations.
[0125] In Fig. 13, "b" simplifies and illustrates detected sizes 511 and 512 which are
measured by the contact operation and the tracing operation on the detected size mea
surement screen 500.
[0126] For example, the detected size becomes large, or small according to a finger size of a
user which is used when performing an operation, or an intensity of contact with the
display surface. In addition, since it is also assumed that an object other than the finger
(for example, a device such as stylus) is used when performing the operation, the
detected size becomes large, or small according to the object which is used in the
operation.
[0127] For example, the detected size 511 denotes a measurement example in a case where a
relatively small object is used, and the detected size 512 denotes a measurement
example in a case where the finger size of the user which is used in the operation is
relatively large. In addition, the finger size shown in "b" of Fig. 13, or the like, is il
lustrated in a size which can be easily recognized for easy descriptions.
[0128] In this manner, the control unit 170 calculates a detected size based on operation in
formation which is output from the input control unit 160. In addition, the control unit
170 maintains the calculated detected size in the size information maintaining unit 171.
[0129] In addition, according to the embodiment of the present technology, an example in
which an electrostatic-type (electrostatic capacity method) touch panel has been
described, however, it is also possible to use a pressure sensitive (resistive film type)
touch panel, or an optical touch panel.
[0130] In addition, according to the embodiments of the present technology, a display
control device such as a radio communication device has been described as an
example. However, it is possible to apply the embodiments of the present technology
to other display control devices (electronic devices) in which a view point position of
the virtual space can be switched, or the enlarged and compacted display is possible.
For example, it is possible to apply the embodiments of the present technology to ap
pliances such as a digital still camera, a digital video camera (for example, cameraintegrated
recorder), a digital photo frame, a smart phone, a tablet, a digital signage
