ABSTRACT:
In a fingerprint sensor that effects capacitive measurement, a sequence of fingerprint images is recorded while a finger is placed on to the sensor. By comparing the best image with previous images of the sequence, the real constituent parts of the present image are determined and the remaining constituent parts are eliminated from the best image. Thus, residual prints and disturbance components brought about by contamination of the bearing area can be eliminated from the fingerprint image.
