Abstract
Methods and apparatus for processing biometric digit data variously include scanning a digit in a transverse direction relative to an array of sensor elements, detecting the scanned digit and/or a predetermined characteristic of the scanned digit, outputting from individual sensor elements of the array of sensor elements respective continuous streams of biometric data associated with the scanned digit, discrete sampling the respective continuous streams of data, and reconstructing the discrete sampled data. The discrete sampled data may be directly reconstructed, e.g., in accordance with a reconstruction characteristic associated with detecting and/or discrete sampling the scanned digit, to form a biometric characteristic image associated with the digit. Optionally, the respective continuous streams of data may be stored for later discrete sampling, or discrete sampled data may be stored for later reconstruction to form a biometric characteristic image associated with the digit.
