ABSTRACT:
A solid-state image pickup device for an electronic camera or the like in which the total picture-taking time is reduced by reducing the time required for performing photometric measurements, which are a necessary preliminary to the actual photographing operation. The light detecting elements of the pickup device are read out for purposes of the photometric measurements at a rate an integer multiple of the rate employed for the ordinary photographing operation.
