Abstract
To prevent a decrease in a saturation charge when a phase difference signal is generated. A pixel includes a plurality of photoelectric conversion sections that is formed on a semiconductor substrate and performs photoelectric conversion of incident light from a subject to generate a charge. An intra-pixel separator separates the plurality of photoelectric conversion sections. An overflow path in the intra-pixel separator transfers charges overflowed in the plurality of photoelectric conversion sections to each other. An overflow gate in the pixel and adjusts a potential of the overflow path. A pixel separator is disposed at a boundary between the pixels. A charge holding section holds the generated charge. A charge transfer section is disposed one-by-one for the plurality of photoelectric conversion sections and transfers the generated charge to the charge holding section. An image signal generating section generates an image signal on the basis of the generated charge.
