Abstract:
1. An image input unit capable of performing pixel shift photography, said image input unit comprising: a photographic optical system which forms an image of a subject in a predetermined position; an image sensing unit which generates image data corresponding to the image of the subject; a pixel shift mechanism which displaces said image sensing unit by a predetermined amount; a pixel shift mechanism control unit which controls said pixel shift mechanism so as to displace said image sensing unit by the predetermined amount; an image combining unit which generates image data for one image by combining the image data for a plurality of images output before and after the displacement of said image sensing unit; and a judgment unit which judges whether the pixel shift photography on the completed combined image has been performed correctly or not, based on comparing the image data from a plurality of images output before the displacement of said image sensing unit with the image data from the plurality of images output after the displacement of said image sensing unit.
