ABSTRACT:
An image pickup unit including a charge coupled solid-state image pickup device prevents the occurrence of smear. Signal charges of a picture element group corresponding to a first field are read and a mechanical shutter is thereafter closed to photo-shield the entire image pickup device when signal charges in the picture element group corresponding to a second field are held temporarily in vertical charge transfer lines.
