Abstract
An image processing device according to an embodiment of the present invention obtains recovery image data by performing restoration processing using a restoration filter based on a point spread function of an optical system, on original image data obtained from an imaging element by imaging using the optical system. The restoration filter used in this restoration processing (a combination filter and realization filter Fr) is generated by combining multiple base filters Fb. Base filter Fb may be arbitrarily selected from filters that are confirmed beforehand to be effective to prevent image quality degradation.
