摘要： An image processing method includes the steps of calculating, with respect to a processing-target pixel in an input image signal, a concentric aberration correction amount for concentric aberration that is a component of magnification chromatic aberration, the concentric aberration causing a color shift to occur in a concentric manner from the center of an image, calculating, with respect to the processing-target pixel, a uniform aberration correction amount for uniform aberration that is a component of magnification chromatic aberration, the uniform aberration causing a color shift direction and a color shift amount to uniformly occur on a whole image, and correcting a pixel value of the processing-target pixel on the basis of the calculated concentric aberration correction amount and the calculated uniform aberration correction amount.
