An optical image formed by a lens system is incident to a CCD, and the CCD performs an electronic shutter operation. The CCD transfers the generated charges by a domino read method. After the electronic shutter operation, a motor is operated to move a shield plate from the lower side to the upper side to enter into an optical path to block the incidence of light to the CCD. On the surface of the CCD, charge transfer is made first, and shielding of light is made successively, from the horizontal charge transfer passage side. With the image pickup device shielding apparatus, the incidence of light can be positively prevented by a simple mechanism during charge transfer in a solid state image pickup device to improve the quality of the image.
