Abstract:
1. An image pickup apparatus comprising: a photoelectric transduction portion to transduce an optical image of a subject formed on an image plane through a lens to output an image signal; a movement portion provided between said photoelectric transduction portion and a base to move said photoelectric transduction portion relative to said base; an illumination portion placed at a predetermined position from said base to emit light onto said image plane of said photoelectric transduction portion in a state in which a shutter is closed to block light entering from said lens; a light-blocking portion placed at a predetermined position from said base to interrupt part of light from said illumination portion at between said illumination portion and said image plane; an adjustment image obtaining portion to obtain an image signal output by said photoelectric transduction portion as a result of photoelectric transduction, in a state in which said illumination portion emits light; and a relative position detection portion to detect a relative position of said photoelectric transduction portion with respect to said base, based on an image of said light-blocking portion that is included in an image based on said obtained image signal.
