Patent ID: 7734074

Claim:
A finger sensor apparatus comprising: a plurality of finger image sensing arrays for generating a respective plurality of finger image data sets based upon sliding finger movement over said plurality of finger image sensing arrays; and a processor cooperating with said plurality of finger image sensing arrays for determining finger movement based upon the plurality of finger image data sets, and for generating a resampled finger image data set by resampling the plurality of finger image data sets based upon the determined finger movement by at least using the determined finger movement to arrange the plurality of finger image data sets into a single array to thereby generate a supersampled finger image data array having a resolution greater than a resolution of each finger image data set, and downsampling the supersampled finger image data array to generate a downsampled finger image data array having a resolution lower than the resolution of the supersampled finger image data array and thereby defining the resampled finger image data set.
