Abstract
A fingerprint imager uses a non-rectangular image readout to reduce the bandwidth and data size of the read-out image. Narrow-width rows in the central portion of the image are used to align successive partial image frames of the fingerprint to reconstruct a full image of the fingerprint using full-width rows of the fingerprint frames.
