Solid state image pick-up device
 A solid state image pick-up device includes a number of picture elements arranged in a matrix form each picture element being constituted by a MOS transistor and a photodiode, gates of the MOS transistors arranged in a vertical direction are connected to respective horizontal scanning lines which are connected to outputs of a horizontal shift register. Drains of the MOS transistors arranged in a horizontal direction are connected to respective vertical scanning lines both ends of which are connected to first and second signal read-out lines via first and second vertical selection switches, respectively. The first and second vertical shift registers produce first and second vertical scanning pulses which are shifted by given time period corresponding to a desired shutter open time. Each picture element is scanned twice by means of the first and second vertical scanning pulses. By adjusting said time period, the shutter open time can be set at with within a wide range.
