More Information
Summary:An imaging device includes pixels including a photoelectric conversion unit, a holding unit that holds charge, and an amplifier unit. The pixels include a first group outputting a signal based on charge generated during a first exposure period, and a second group outputting a signal based on charge generated during a second exposure period longer than the first exposure period. The pixel belonging to the second group includes in the second exposure period a first period during which the charge generated in the photoelectric conversion unit is accumulated in the photoelectric conversion unit, and the charge held by the holding unit is transferred to the amplifier unit, and a second period during which the charge generated during the first period is held in the holding unit, and the charge generated after the first period is held by one of the photoelectric conversion unit and the holding unit.
