摘要：
An image capturing apparatus includes 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.
