Image quality can be improved. In a case where light is focused on the center of an opening, sensitivity can be decreased by extending any side of a light-shielding film to the center. Namely, in the case of adjusting the sensitivity to be decreased, there is no need to simultaneously change all the sides, but the adjusting may be achieved by moving only a specific side. Further, since each side is regarded as individual adjusting parameter, a complicated inside-angle-of-view distribution can be corrected. The present disclosure can be applied to, for example, a CMOS solid-state imaging device to be used in an imaging device such as a camera.
