Patent ID: 7772616

Claim:
A solid-state imaging device comprising a semiconductor substrate and a plurality of photoelectric conversion elements provided in the semiconductor substrate, wherein the plurality of photoelectric conversion elements comprise: effective photoelectric conversion elements which are photoelectric conversion elements for obtaining an imaging signal corresponding to light from a subject; and OB photoelectric conversion elements which are photoelectric conversion elements for obtaining a reference signal of an optical black level, and the solid-state imaging device further comprises a first shielding layer provided at least over an effective pixel area and having an opening provided at least over a part of the effective photoelectric conversion elements, and a second shielding layer provided over an OB pixel area and electrically separated from the first shielding layer, wherein the effective pixel area is an area of the semiconductor substrate where the effective photoelectric conversion elements are provided and the OB pixel area is an area of the semiconductor substrate where the OB photoelectric conversion elements are provided.
