[003] Identifying and capturing fingerprints are essential activities for forensic
experts and policemen to identify criminals in various cases. However, identifying and
15 capturing fingerprints are very difficult task even for forensic experts and policemen. The
process of taking fingerprints and printing the captured fingerprint is very tedious and time
consuming due to the requirement of sophisticated devices. Also, currently available methods
to prepare the image of the correct fingerprints have many problems. In view of tedious
process, the forensic experts and policemen take more time to solve any case.
20 [004] Therefore, there is a need to provide a portable fingerprint capturing device
that is simple, faster, cost-effective and capable of providing high quality images of
fingerprints.
OBJECTS OF THE PRESENT INVENTION
25 [005] An object of the present invention is to provide a portable fingerprint capturing
device that provides high quality image of fingerprints.
[006] Another object of the present invention is to provide a portable fingerprint
capturing device a wireless communication module (Bluetooth) to connect the device with
other communication device.

various methods described herein, and the method steps of the invention could be
accomplished by modules, routines, subroutines, or subparts of a computer program product.
[0028] Exemplary embodiments will now be described more fully hereinafter with
15 reference to the accompanying drawings, in which exemplary embodiments are shown. These
exemplary embodiments are provided only for illustrative purposes and so that this disclosure
will be thorough and complete and will fully convey the scope of the invention to those of
ordinary skill in the art. The invention disclosed may, however, be embodied in many
different forms and should not be construed as limited to the embodiments set forth herein.
20 Various modifications will be readily apparent to persons skilled in the art. The general
principles defined herein may be applied to other embodiments and applications without
departing from the scope of the invention. Moreover, all statements herein reciting
embodiments of the invention, as well as specific examples thereof, are intended to
encompass both structural and functional equivalents thereof. Additionally, it is intended that

infringement purposes is recognized as including equivalents to the various elements or
limitations specified in the claims. Depending on the context, all references below to the
"invention" may in some cases refer to certain specific embodiments only. In other cases, it
5 will be recognized that references to the "invention" will refer to subject matter recited in one
or more, but not necessarily all, of the claims.
[0030] All methods described herein can be performed in any suitable order unless
otherwise indicated herein or otherwise clearly contradicted by context. The use of any and
all examples, or exemplary language (e.g., “such as”) provided with respect to certain
10 embodiments herein is intended merely to better illuminate the invention and does not pose a

[0033] As used herein, and unless the context dictates otherwise, the term "coupled
to" is intended to include both direct coupling (in which two elements that are coupled to
each other contact each other) and indirect coupling (in which at least one additional element
is located between the two elements). Therefore, the terms "coupled to" and "coupled with"
25 are used synonymously. Within the context of this document terms "coupled to" and "coupled
with" are also used euphemistically to mean “communicatively coupled with” over a
network, where two or more devices are able to exchange data with each other over the
network, possibly via one or more intermediary device.

printed if the preview is clear.
10 [0037] In another embodiment of the present invention, when a person places his
finger on the portable fingerprint capturing device, ultraviolet radiation flows and scans the
fingerprint with high resolution. Captured image of fingerprint is displayed on the display
unit, and if captured image is not perfect, finger can be scanned again. And, captured
fingerprint can be printed easily, by connecting the device with printer through Bluetooth.
15 [0038] In yet another embodiment, the portable fingerprint capturing device scan the

the device with printer through Bluetooth.
20 [0039] In an embodiment of the present invention, the scanned image of the
fingerprint is processed by a processing unit, afterwards it is transmitted to printer or other
device through Bluetooth.
[0040] As illustrated in Fig. 2 is the flowchart for processing unit of the portable
fingerprint capturing device of the present invention. The processing of image comprises the
25 following steps: i) grayscale transformation of image, ii) normalization of image, iii) first
segmentation of image, iv) directional mapping of image, v) second segmentation of image
and vi) filtering of image.

materials are captured quickly and efficiently by portable fingerprint capturing device thereby
very useful for forensic experts and policemen to identify the fingerprints in efficient manner.
10 [0044] It should be apparent to those skilled in the art that many more modifications
besides those already described are possible without departing from the inventive concepts
herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of
the appended claims. Moreover, in interpreting both the specification and the claims, all
