Abstract
An image pickup apparatus includes an element-including optical system, a variable aperture, a detector, and a converter. The element-including optical system has an optical system and an optical wavefront modulation element which modulates an optical transfer function. The detector picks up an object image that passes through the optical system, the variable aperture, and the optical wavefront modulation element. The converter generates an image signal with a smaller blur than that of a signal of a blurred object image output from the detector. Positions at which the element-including optical system and the detector are attached are adjusted by stopping down a variable aperture included in the element-including optical system.
