The image processing method includes a step of acquiring an image generated by image pickup through an optical system, and a step of performing image restoration processing on the image using an image restoration filter created such that its filter values have a two-dimensional distribution based on aberration information of the optical system. The image restoration filter is a filter in which a position of a cell having a maximum absolute value among the filter values is shifted with respect to a position of a center cell of the image restoration filter by a shift amount according to one of an amount of distortion of the optical system and an amount of chromatic aberration of magnification of the optical system, and which reduces a blur component of the image and at least one of a component of distortion and a component of chromatic aberration of magnification of the image.
