Abstract
A finger biometric sensor may include an array of finger biometric sensing pixels, and processing circuitry coupled to the array of finger biometric sensing pixels. The processing circuitry may be capable of collecting initial enrollment finger biometric data sets and generating an initial enrollment criteria based thereon, collecting at least one additional enrollment finger biometric data set, and adapting the initial enrollment criteria based thereon to define an additional enrollment criteria. The processing circuitry may also be capable of flagging the initial enrollment finger data sets and the at least one additional enrollment finger data set as sufficient if the additional enrollment criteria meets an acceptance condition, and collecting further enrollment finger biometric data and adapting the additional enrollment criteria if the additional enrollment criteria fails to meet the acceptance condition.
