US Patent 11523078 Solid-state imaging device and electronic apparatus

Provided is a solid-state imaging device and an electronic apparatus capable of achieving both of a high dynamic range operation and an auto focus operation in a pixel configuration in which a plurality of unit pixels includes two or more subpixels. The solid-state imaging device includes a first pixel separation region that separates a plurality of unit pixels including two or more subpixels, a second pixel separation region that separates each of the plurality of unit pixels separated by the first pixel separation region and an overflow region that causes signal charges accumulated in the subpixels to overflow to at least one of adjacent subpixels, in which the overflow region is formed between a first subpixel and a second subpixel.
