An image processing apparatus includes an image pickup circuit that performs photoelectric conversion on an optical image, and a chromatic aberration correcting circuit that calculates an amount of shift by chromatic aberration based on a linear function to perform chromatic aberration correction on captured image data in accordance with the amount of shift. The chromatic aberration correcting circuit performs the chromatic aberration correction on a first pixel in a first area including an optical center of the captured image data with a first linear function using a distance from the optical center, and performs the chromatic aberration correction on a second pixel in a second area that does not include the optical center and that is different from the first area with a second linear function using the distance from the optical center.
