Abstract:
A fingerprint sensor system includes a fingerprint area sensor  130  having an array of pixels and a fingerprint processor  128  for processing a signal from the fingerprint area sensor  130.  A process for calibration of this system comprises: determining a gain matrix of pixel gain values by performing a scan of the fingerprint area sensor  130  when it is presented with a homogenous target that covers all of the pixels; determining an offset noise matrix of pixel offset noise values by performing a scan of the fingerprint area sensor  130  when nothing is presented to the fingerprint area sensor  130;  and arranging the fingerprint processor  128  to store the information from the gain matrix and the offset noise matrix as calibration information and to use this calibration information to correct fingerprint data obtained from the fingerprint area sensor  130  during later use of the fingerprint sensor  130.

Claim (Index 17):
