Abstract

An imaging device includes pixels each of which includes a microlens and a plurality of photoelectric conversion units. The pixels include a first pixel and a second pixel adjacent to the first pixel, a first photoelectric conversion unit included in the first pixel and a second photoelectric conversion unit included in the second pixel are configured to share a first floating diffusion unit, sensitivity of the second photoelectric conversion unit is lower than sensitivity of the first photoelectric conversion unit in a wavelength range in which the first photoelectric conversion unit has a peak of the sensitivity, and a charge of a photoelectric conversion unit other than the first photoelectric conversion unit and the second photoelectric conversion unit is read from a floating diffusion unit different from the first floating diffusion unit in each of the first pixel and the second pixel.
