Abstract

See full text

An image processing apparatus performs image processing for correcting a lateral chromatic aberration that contains a rotationally symmetrical component and a shift component, for an input image generated by image capturing using an optical system. The image processing apparatus includes a first acquirer configured to acquire first component information on a first component that is one of the rotationally symmetrical component and the shift component, the first component information being acquired and stored before the input image is acquired, a second acquirer configured to acquire the second component information on a second component that is the other of the rotationally symmetrical component and the shift component based on the color shift amount, by using the input image and the first component information, and a corrector configured to perform a correction process with the first component information and the second component information for the input image.
