PURPOSE:To control the incident luminous quantity by controlling electrically the storage time of an electric charge read from a photoelectric conversion element of a solid-state image pickup element during one vertical scanning period without using a mechanical shutter. CONSTITUTION:The electric charge stored in a photoelectric conversion element 7 of a solid-state image pickup element 31 is read into a vertical transfer means 8 by a read pulse fed to a gate 13 during the vertical blanking period. The electric charge transferred to the transfer means 8 is transferred at a high speed in the direction of a horizontal transfer register 15 by using a high-speed transfer pulse placed between the said read pulses. Thus, the storage time of the signal charge stored in the photoelectric conversion element 7 is controlled pure-electrically, then the incident luminous quantity is controlled by the same performance as a conventional mechanical shutter.
