Abstract
Biometric imaging devices and methods of processing images of biometric surfaces that are captured using the imaging device including capturing an image of a biometric surface presented by an individual by a sensor of the imaging device, either as a single image or as a plurality of overlapping image portions that are combinable to form a single composite image. The imaging device also includes a memory buffer for retrievably storing image data relating to the image of the biometric surface. A processor of the imaging device is provided for analyzing the stored image data to determine a location of a feature of interest and for providing an output image of a known size and shape for use by a host system that is in communication with the imaging device for identifying the individual.
