Abstract: A finger biometric sensor may include an array of finger biometric sensing pixels and processing circuitry coupled thereto. The processing circuitry may be capable of acquiring initial data from the array based upon an initial drive signal level and with a finger positioned adjacent the array, and determining an updated drive signal level based upon the initial data. The processing circuitry may also be capable of acquiring finger biometric data from the array of finger biometric sensing pixels based upon the updated drive signal level and with the finger positioned adjacent the array.
