Abstract
A restoration filter based on a point spread function of an optical system is applied to source image data acquired through photographing using the optical system to acquire restored image data (S13: filter application step). Adjustment of an amplification factor of the difference between source image data and restored image data is performed, and recovered image data is acquired from the difference after adjustment and source image data (S15: gain adjustment step). In the filter application step, a common filter determined regardless of a value of a magnification of an optical zoom of the optical system is used as the restoration filter, and in the gain adjustment step, the amplification factor is determined based on the magnification of the optical zoom of the optical system.
