Abstract
An image processing apparatus () includes: an imaging device (); an optical system (); and a distance determining unit () determining an object distance between the optical system and the object based on a size of a blur developed on the image. The optical system () has a characteristic which simultaneously satisfies both of conditions that (i) variation in magnification is equal to or smaller than the predetermined number of pixels in the case where a focused point is set farthest from and closest to the optical system () in a range of the distance of the object determined by the distance determining unit () and (ii) variation in a PSF due to an image height of the optical system () is equal to or smaller than a predetermined degree so as not to affect the determination of the distance of the object by the distance determining unit ().
