A chromatic aberration of magnification is corrected by performing a coordinate transformation with respect to image data including chromatic aberration of magnification, which is obtained from a fisheye optical system, based on   { X = x + ax Y = y + by where x and y represents coordinates of a transformation destination with a center of a screen as an origin, X and Y represents coordinates of a transformation source with the center of the screen as an origin, and a and b are coordinate transformation coefficients.
