ABSTRACT:
A solid-state image pickup device has an image pickup element with a light-receiving surface on which a plurality of photoelectric conversion cells are arranged; a timing circuit, coupled to at least one and less than all of said photoelectric conversion cells of the image pickup element, for generating a timing signal when an output level of the photoelectric conversion cell corresponding to the amount of light incident on the photoelectric conversion cell connected thereto reaches a predetermined reference level; and a data reading unit coordinated with a shutter, coupled to the timing circuit for optically shielding the light-receiving surface of the image pickup element in response to the timing signal. The data reading unit reads image data on the light-receiving surface in an interval following the timing signal.
