Patent ID: 8730357

Claim:
An image processing device comprising: a concentric aberration correction amount calculation unit configured to calculate, 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 such that the color shift continuously increases as a distance from the center of the image increases for all pixels in the input image signal, the concentric aberration correction amount calculation unit calculating the concentric aberration correction amount based on an aperture value, a zoom position, a focus position, an image height value, and a color, the concentric aberration correction amount calculation unit calculating the concentric aberration correction for at least two of three colors; a uniform aberration correction amount calculation unit configured to calculate, 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, the uniform aberration correction amount calculation unit calculating the uniform aberration correction amount based on the aperture value, the zoom position, the focus position, and the color; and a pixel value correction unit configured to correct 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.
