System for determining the motion of a fingerprint surface with respect to a sensor surface
Abstract:
A fingerprint motion tracking method and system is provided for sensing features of a fingerprint along an axis of finger motion, where a linear sensor array has a plurality of substantially contiguous sensing elements configured to capture substantially contiguous overlapping segments of image data. A processing element is configured to receive segments of image data captured by the linear sensor array and to generate fingerprint motion data. Multiple sensor arrays may be included for generating directional data. The motion tracking data may be used in conjunction with a fingerprint image sensor to reconstruct a fingerprint image using the motion data either alone or together with the directional data.
