PROBLEM TO BE SOLVED: To provide an image apparatus, and an arithmetic unit or its arithmetic program, capable of processing excellent image restoration without an adverse effect even when an out-focus state and a manufacturing error state of an optical system are found with a small optical information amount.SOLUTION: An imaging apparatus is characterized in having, in a plurality of image heights, crossing distance measurement means capable of detecting a defocus state in the direction corresponding to sagittal and meridional of an optical system with respect to a distance measurement point during photographing, having optical information capable of representing the defocus state of the optical system and an image forming state in accordance with the image height by sagittal components and meridional components, respectively, and having means for creating an image restoration filter on the basis of each defocus state in a sagittal direction and in a meridional direction and optical image forming information.SELECTED DRAWING: Figure 8-1 |
