Claim One:
1. A system for capturing biometric data of a hand comprising: an enclosure having an opening adapted to receive a hand in a first orientation; a low resolution camera within the enclosure, wherein the camera is positioned substantially perpendicular to the palm of the hand so as to capture the palm, fingers and thumb of the hand in a single image; a plurality of high resolution cameras arranged in a substantially arc-shaped configuration, wherein the high resolution cameras are positioned to capture images corresponding to respective sections of a biometric region of the hand, wherein the images captured by said high resolution cameras, when combined, span the biometric region of the hand; a plurality of lights within the enclosure positioned to illuminate each respective section of the biometric region from at least three different directions; and a processor connected to the low resolution camera, the high resolution cameras and the lights, wherein the processor is configured to: receive first image data of the hand positioned in the first orientation from the low resolution camera; analyze the first image data to determine if the first orientation of the hand is in the optimal orientation; flash the lights; receive second image data of the respective sections of the biometric region from the high resolution cameras; construct a gross map of the hand using the first image data; tile the second image data onto the corresponding areas of the gross map; match friction ridges between adjacent images of the second image data; and perform a pixel selecting algorithm of the images in the second image data to select pixels which show the greatest contrast between the peaks and valleys of the friction ridges.
