Claim Text:
1. An image processing device comprising: a statistical information acquiring processor that acquires statistical information related to point image restoration of an image; an optical information acquiring processor that acquires optical information indicating a point image intensity distribution of an optical system used when the image is acquired, the optical information including: information indicating a kind of symmetry of the point image intensity distribution; and compressed information capable of reproducing the point image intensity distribution according to the kind of the symmetry of the point image intensity distribution and being associated with the information indicating the kind of the symmetry of the point image intensity distribution; a filter information calculating processor that obtains filter information of a restoration filter for point image restoration processing of the image according to the optical information alone or in combination with the statistical information, the filter information including information related to number of taps of the restoration filter and information indicating a kind of symmetry of the restoration filter, the filter information calculating unit obtaining the information indicating the kind of the symmetry of the restoration filter from the information indicating the kind of the symmetry of the point image intensity distribution and obtaining the information related to the number of the taps of the restoration filter according to the statistical information and the compressed information associated with the information indicating the kind of the symmetry of the point image intensity distribution; and a filter coefficient calculating processor that calculates a filter coefficient of the restoration filter according to the optical information alone or in combination with the statistical information with at least the information related to the number of the taps of the restoration filter and the information indicating the kind of the symmetry of the restoration filter of the filter information as a constraint condition.
