  • Publication number: 20220311943
    Abstract: An error is reduced in phase difference detection of an imaging element including a phase difference pixel with an on-chip lens in common for a pair of pixels. The imaging element includes a pixel, an individual on-chip lens, a plurality of phase difference pixels, a common on-chip lens, and a pixel circuit. The individual on-chip lens individually collects incident light for each pixel. The phase difference pixels are arranged adjacent to each other to detect a phase difference. The common on-chip lens is arranged in common for the plurality of phase difference pixels and collects incident light in common. The pixel circuit is formed in a semiconductor substrate and generates an image signal on the basis of a transferred charge. Charge transfer units of the plurality of phase difference pixels are in a region between the common on-chip lens and the individual on-chip lens.
