Abstract
An apparatus for culling substantially redundant data in a fingerprint sensing circuit is disclosed in one embodiment of the invention as including an input module, a storage module, a comparator module, and a determination module. The input module may receive sets of data samples from an array of fingerprint sensing elements. The sets of data samples may be stored by the storage module. The comparator module may calculate a difference between each data sample from a first-received set, and a corresponding data sample from a second-received set. The determination module may count the number of difference values that exceed a predetermined difference limit, and identify the second set of data samples as redundant if the number of difference values counted is less than a pre-set count limit.
