Image pickup apparatus and reference position detection method |
摘要 |
An image pickup apparatus includes: 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 the photoelectric transduction portion and a base to move the photoelectric transduction portion relative to the base; an illumination portion placed at a predetermined position from the base to emit light onto the image plane of the photoelectric transduction portion in a state in which a shutter is closed to block light entering from the lens; a light-blocking portion placed at a predetermined position from the base to interrupt part of light from the illumination portion at between the illumination portion and the image plane; an adjustment image obtaining portion to obtain an image signal output by the photoelectric transduction portion as a result of photoelectric transduction, in a state in which the illumination portion emits light; and a relative position detection portion to detect a relative position of the photoelectric transduction portion with respect to the base, based on an image of the light-blocking portion that is included in an image based on the obtained image signal. |
