| 1. A method of imaging a biometric sample comprising:
receiving biometric image data based on a sensed biometric sample;
analyzing a pattern of the biometric image data with a processor to determine a location of at least a repeatably identifiable
feature within the pattern of the biometric image data;
constructing a composite image from a plurality of received image portions with the processor, wherein the composite image
comprises the biometric image data including the at least a repeatably identifiable feature, wherein said constructing of
a composite image is performed at least partially during said analyzing of the biometric image data; and
providing an image of a known size that contains only a portion of the pattern and excludes another portion of the pattern
of the biometric image data, the provided image sensed at locations of the biometric sample near the determined location of
the at least a repeatably identifiable feature.
