Patent attributes
An image shifting apparatus may capture multiple frames of an image, with each frame offset by a sub-pixel offset distance. After capture, the various sub-pixel offset images may be registered together and analyzed using known resolution enhancement algorithms. Super resolution algorithms, for example. may take the various frames and perform edge identification and peak extraction routines to improve the resolution of high frequency data within an image. The image shifting apparatus may include an actuation controlled optical compensator within the imaging system that may be adjusted to create a sub-pixel offset image of an original reference image. The optical compensator may be an image-stabilizing element, for example, capable of forming sub-pixel shifts in an image plane.
