Abstract
The present invention provides a large format fingerprint capture apparatus, system and method that is low power, compact, and lightweight and has a platen area greater than 3.0 square inches. The present system is typically powered, controlled, and exchanges data over a single data/control/power connection to a host PC, e.g., a desk top computer, PDA, or laptop computer although the system can also be used in a wireless fashion with a power subsystem so no physical connections are required.
Claims14
A system configured to generate a composite image of a friction ridge signature of a subject, the system comprising:
- a platen comprising a first light-reflecting surface;
- a light source configured to emit light rays to illuminate a subject placed in contact with the first light-reflecting surface of the platen;
- a camera configured to capture images of the subject in contact with the first light-reflecting surface of the platen, through the platen, in an ongoing manner;
- and
- a processor configured to receive images of the subject captured by the camera, and to automatically determine whether a sequence of the received images includes a successful capture sequence, wherein a determination that the sequence of received images includes a successful capture sequence is made responsive to identification by the processor of a trigger in the sequence of received images indicating the beginning of a capture sequence and identification by the processor of a trigger in the sequence of received images indicating the completion of the capture sequence.
A method of generating a composite image of a friction ridge signature of a subject, the method comprising:
- emitting light rays toward a platen comprising a first light-reflecting surface to illuminate a subject placed in contact with the first light-reflecting surface of the platen;
- capturing images of the subject in contact with the first light-reflecting surface of the platen, through the platen, in an ongoing manner;
- and
- executing one or more modules on one or more processors to automatically determine whether a sequence of the received images includes a successful capture sequence, wherein a determination that the sequence of received images includes a successful capture sequence is made responsive to identification by the processor of a trigger in the sequence of received images indicating the beginning of a capture sequence and identification by the processor of a trigger in the sequence of received images indicating the completion of the capture sequence.
