Image capturing apparatus, image capturing method, image processing apparatus, image processing method, and program storing medium using spatial frequency transfer characteristics

摘要

An image capturing apparatus includes an optical system that forms an image of light and a gradation processing section that converts gradation of a captured image captured through the optical system in accordance with a spatial frequency transfer characteristic of the optical system. The image capturing apparatus may further include a light receiving section that receives light from a subject through the optical system, and the gradation processing section may convert gradation of a captured image obtained by light received by the light receiving section in accordance with a spatial frequency transfer characteristic at the position at which the light receiving section is provided.
