Patent 7929774 was granted and assigned to Intel on April, 2011 by the United States Patent and Trademark Office.
Digital image processing of a low resolution source image to produce a high resolution result image may be accomplished by partitioning the low resolution source image into a plurality of low resolution image parts; for each low resolution image part, comparing the low resolution image part to low resolution reference images to determine at least one most similar low resolution reference image; determining if the most similar low resolution reference images are related to one another; and constructing a high resolution result image based at least in part on high resolution images corresponding to related most similar low resolution reference images.
