Abstract:
1. 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.
