Abstract:
An image processing apparatus includes an image obtaining unit, a color shift detecting unit, a controlling unit, and a correction amount calculating unit. The image obtaining unit obtains image data. The color shift detecting unit detects color shifts of this image data. The controlling unit determines fitting reliability of the color shift detection result and selects a magnification chromatic aberration model suitable for color shift fitting according to the reliability. The correction amount calculating unit fits the magnification chromatic aberration model selected by the controlling unit to the color shift detection result and obtains correction amounts of the magnification chromatic aberration for the image data.
