PURPOSE:To obtain a solid-state image pickup device which can constitute the small-sized light electronic still camera by providing an accumulating part to transfer the charge accumulated said photodetecting part besides the photodetecting part, in respective picture elements of the solid-state image pickup element. CONSTITUTION:The first-third scanning circuits 13-15, at the time t1 of starting the image pickup, generate the resetting pulse, turns on the gate of the first-third MOS transistors (TR)7-9, resets a photodetecting part 16 and an accumulating part 17 of all unit picture elements and sets the initial condition. A light carrier generated by the light to make incident during the desired shutter time t2-t1 is accumulated at the photo-detecting part 16 of the TR 7. Next, the circuit 13, in the time t2, generates a shutter pulse and turns on the gate of the TR 7 only once concerning all picture elements. Thus, in the time t2, the charge in proportion to the charge accumulated at the photodetecting part 16 is transferred to the accumulating part 17. In the same way, to scan all picture elements, circuits 14 and 15 also generate the pulse to turn on the gate of TRs 8 and 9 successively, and from the time t31, the data of respective picture elements are read.
