A system and method for increasing image resolution in a palm print scanner.
The
method of the invention requires the synchronization of a nutating mirror with
a camera frame sync. A first image is scanned at a first nutation position. The
mirror is nutated by a fraction of a pixel amount in one direction. Another image
is scanned at a second nutation position. The process of nutating the mirror to
a different nutation position and scanning an image is repeated until all sub-pixels
needed to increase an image resolution are obtained. All of the sub-pixels obtained
are then interlaced to obtain a higher resolution image.
