Patent ID: 7420592

Claim:
A method of enhancing resolution of an image, the method comprising: providing a photodetector; capturing a first image at a first pixel position on the photodetector; integrating a signal from a vibration sensor to determine image shift due to motion of an optical element; calculating an amount of offset for an optical compensator to shift the first image a predetermined sub-pixel amount including the image shift due to the motion of the optical element; providing a sub-pixel offset signal to the optical compensator in the calculated amount of the offset; moving the optical compensator to form at least one additional image at a second pixel position offset from the first pixel position by a sub-pixel offset distance; capturing the at least one additional image; comparing the first image to the at least one additional image; in response to the comparison of the first image and the at least one additional image, deriving an enhanced resolution image; and identifying an edge in the enhanced resolution image, the edge having varying intensities based on the comparison of the first image and the at least one additional image; determining a region of peak intensity for the edge of the enhanced resolution image; and in response to the determination of the region of peak intensity, enhancing a resolution of the edge by narrowing the edge to the peak intensity region.
