ABSTRACT:
An image processing system for restoring a resolution of a pixel-mixed image represented by a mixed-pixel signal which is acquired when a plurality of pixel signals in an image pickup device are mixed and are read out includes a shooting situation acquiring section, a restoration matrix generating section, and a restoration processing section. The shooting situation acquiring section acquires a shooting situation when the mixed-pixel signal is acquired. The restoration matrix generating section generates a pixel mixture restoration matrix based on the shooting situation acquired by the shooting situation acquiring section. The restoration processing section restores a resolution of the pixel-mixed image using the mixed-pixel signal and the pixel mixture restoration matrix.
