Abstract
An imaging device includes pixels including a photoelectric conversion unit, a holding unit holding charge transferred from the photoelectric conversion unit, and an amplifier unit outputting signal based on the charge. The pixels output a first signal based on charge generated in a first exposure period and a second signal based on charge generated in a second exposure period of different length. In the first exposure period, the photoelectric conversion unit accumulates the generated charge, and charge held by the holding unit is transferred to the amplifier unit. The second exposure period includes a period of accumulating the generated charge only in the photoelectric conversion unit and a period of holding the generated charge in the photoelectric conversion unit and the holding unit. In the period of accumulating the generated charge only in the photoelectric conversion unit, the charge held by the holding unit is transferred to the amplifier unit.
