Palm scanner using a programmable nutating mirror for increased resolution |
摘要 |
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.
