Abstract: An imaging device includes: a semiconductor substrate; a first photoelectric converter which is disposed in the semiconductor substrate; a second photoelectric converter different from the first photoelectric converter, which is disposed in the semiconductor substrate; a wiring layer disposed on or above the semiconductor substrate; and a capacitor which is disposed in the wiring layer and surrounds the first photoelectric converter in plan view. The capacitor includes a first electrode, a second electrode, and a dielectric layer disposed between the first electrode and the second electrode. The first electrode is connected to one of the first photoelectric converter and the second photoelectric converter.

Abstract: A solid-state imaging apparatus includes a plurality of high-sensitivity pixels that are arranged in a matrix, and perform a photoelectric conversion at a predetermined sensitivity; a plurality of low-sensitivity pixels that are arranged in a matrix in gaps between the plurality of high-sensitivity pixels, and perform a photoelectric conversion at a lower sensitivity than the predetermined sensitivity; and a signal processor that generates a pixel signal by (i) detecting a difference signal between a signal from the plurality of high-sensitivity pixels and a signal from the plurality of low-sensitivity pixels, and (ii) correcting the signal from the plurality of high-sensitivity pixels using the difference signal.
