1. A finger biometric sensor comprising: an array of finger biometric sensing pixels; and processing circuitry configured to acquire finger biometric data from the array of finger biometric sensing pixels, determine one of a finger sliding motion and a finger static positioning, when the finger is determined to be in sliding motion adjacent the array of finger biometric sensing pixels acquire further finger biometric data from a section of the array of finger biometric sensing pixels, and generate image data from the further finger biometric data based upon the finger sliding motion, when the finger is determined to be statically positioned adjacent the array of finger biometric sensing pixels acquire further finger biometric data from the array of finger biometric sensing pixels by acquiring a sequence of finger biometric data sets from respective overlapping pixel sets of the array of finger biometric sensing pixels and comparing finger biometric data from neighboring pixels along a border between overlapping pixel sets, and generate image data from the further finger biometric data based upon the finger static positioning, and determine a match between the image data and enrolled image data.
