SOLID-STATE IMAGE PICKUP DEVICE Abstract of the Disclosure In a solid-state image pickup device photoelectric conversion elements arrayed in a two-dimensional pattern, horizontal and vertical switches for selecting the photoelectric conversion elements, and horizontal and vertical scanning circuits for turning the switches "on" and "off" are integrated on an identical semiconductor substrate. In order to produce a device of low capacitive lag and high resolution power, the required minimum number (four) of switching elements adapted to turn "on" and "off" in a predetermined combination for every field are connected to an output terminal of each of unit circuits which constitute the vertical scanning circuit. Using an output scanning pulse from the vertical scanning circuit and a field pulse, an interlaced scanning is achieved in which two row lines are simultaneously selected in one of combinations differing for the respective fields, so as to take out an optical image through the vertical switches.
