ABSTRACT:
The present invention relates to a CCD (Charge Coupled Device) solid-state image pickup element with a MOS (Metal Oxide Semiconductor) structure which is used for an image input device such as a TV camera. A reset electrode is provided on the overflow control gate or on the channel stop located between the vertical transfer CCD and the overflow drain of the adjacent picture element, and signal charges on the photosensitive part are discharged through the V-CCD by applying a reset voltage to said reset electrode. Through such an operation, the shutter speed is improved by substantially curtailing the image accumulation time (exposure time) and the stationary image of a moving object can be obtained without using strobes.
