摘要

An image processor includes a correction signal generator (202) configured to generate a correction signal by calculating a difference between an image and an image obtained by applying an unsharp mask generated based on a PSF corresponding to an image-pickup conditions of an image-pickup optical system to the image, and a correction signal applier (203) configured to sharpen the image by multiplying the correction signal generated by the generator by a constant and by adding a multiplied correction signal to the image.
