Abstract:
1. An image capturing apparatus comprising: an optical system that focuses light from a subject; a light receiving section that includes a plurality of light receiving elements for receiving the light from the subject that is focused by the optical system; a correcting section that corrects, in accordance with an optical transfer function of the optical system, a plurality of pixel values that are linearly related to amounts of the light received by the plurality of light receiving elements; and a non-linear processing section that converts the plurality of pixel values that have been corrected by the correcting section into a plurality of pixel values that are non-linearly related to the amounts of the light received by the plurality of light receiving elements, wherein each of the plurality of light receiving elements included in the light receiving section receives light of a corresponding one of a plurality of color components comprising R, G, and B components; and wherein the correcting section corrects the plurality of pixel values for each of the plurality of color components in accordance with a plurality of optical transfer functions of the optical system, each corresponding to one of the plurality of color components; and further comprising a region identifying section that identifies, in an image in which the plurality of pixel values are corrected by the correcting section, a partial region in which an optical response of the optical system is excessively corrected; and a correction control section that controls an intensity of the correction by the correcting section in the partial region identified by the region identifying section.
