IMAGE PROCESSING APPARATUS, IMAGE PICKUP APPARATUS, AND STORAGE MEDIUM FOR STORING IMAGE PROCESSING PROGRAM

摘要

An image processing apparatus includes an image acquirer configured to acquire an input image generated by an image pickup apparatus that controls exposure of an image sensor with a light flux from an image pickup optical system using a shutter, and a processor configured to perform image restoration processing for the input image using an image restoration filter generated based on an optical transmission function from the image pickup optical system to the image sensor in the exposure. When one of a front curtain and a back curtain in the shutter is an electronic curtain and the other is a mechanical curtain, the processor uses, for the image restoration filter, a first image restoration filter generated based on the optical transmission function in a state where the mechanical curtain partially shields the light flux from the image pickup optical system to the image sensor.
