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.
Claims18
An image processing device that 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,
- wherein the restoration filter includes a combination filter generated by combining multiple base filters so as to fit to an ideal filter based on the point spread function.
An image processing device that 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,
- wherein the restoration filter includes a combination filter generated by combining multiple base filters that do not cause ringing in recovery image data obtained in a case where restoration processing using each of the multiple base filters alone is performed on the original image data.
An image processing device that 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,
- wherein the restoration filter includes a combination filter generated by combining multiple base filters that do not emphasize return noise in recovery image data obtained in a case where restoration processing using each of the multiple base filters alone is performed on the original image data.
