Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To enable one soled-state image pickup device to be used for both EIA and CCIR systems by making an external selection signal select whether or not a part of plural vertical clock signals is supplied to a vertical gate electrode. SOLUTION: The 92 lines of the 493rd and succeeding lines are controlled vertically in order to apply a solid-state image pickup device that consists of 584 vertical effective pixel lines to an ETA system that consists of 492 lines. At that time, a vertical transfer clock selective outputting part 55 controls vertical transfer clock that transfers electric charge from a photodiode area 51 of the device to a vertical electric charge transfer area 52. For this, the part 55 makes vertical transfer clocks VΦ1 to 4 input and decides an output in either CCIR or EIA system in accordance with an external selection signal S. The control of the vertical transfer clock applies the vertical transfer clock to entire pixel lines including excessive 92 lines when a transfer gate output is high, and it does not apply the vertical transfer clock to the excessive 92 lines when the output is low.  Therefore, no electric charge is transferred from excessive pixels to the area 52.
