Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate having a surface; three or more pixel regions formed in at least one direction of two different directions along the principal surface of the semiconductor substrate, the three or more pixel regions comprising a central pixel region and peripheral pixel regions around the central pixel region, each pixel region including a plurality of photoelectric conversion regions having different sensitivities, wherein the photoelectric conversion region having the highest sensitivity in the peripheral pixel regions has a higher sensitivity than the photoelectric conversion region having the highest sensitivity in the central pixel region; and a signal processing circuit configured to process a signal that is photoelectrically converted by the pixel regions, the signal processing circuit being included in or being external to the solid-state imaging device, wherein the signal processing circuit corrects for gains of the central pixel region and the peripheral pixel regions in accordance with an f value and corrects for shading that is caused in a region other than the photoelectric conversion regions having the highest sensitivity in the pixel regions, and the signal processing circuit includes:
