1. An image processing device to correct chromatic aberration of image data, the image processing device comprising:

  • overexposed pixel detecting means for detecting overexposed pixels by using a luminance signal of the image data;

    overexposure distribution information generating means for generating overexposure distribution information indicating distribution of the overexposed pixels detected by the overexposed pixel detecting means; and

    chromatic aberration amount calculating means for calculating an amount of chromatic aberration of each pixel by using the overexposure distribution information generated by the overexposure distribution information generating means and chromatic aberration amount distribution information indicating the distribution of the amount of chromatic aberration, which is an amount of correction regarding chromatic aberration of nearby pixels due to overexposure of a target pixel, the chromatic aberration amount calculating means calculating the amount of chromatic aberration of each pixel by adding a contribution value of chromatic aberration from each of a plurality of overexposed pixels within a correction range of the target pixel.
