Abstract
An imaging device includes a plurality of pixels, each of which including a first pixel element including a first photoelectric conversion unit, and a second pixel element including a second photoelectric conversion unit lower in sensitivity than the first photoelectric conversion unit, a readout circuit configured to read out a first image signal based on signal charge generated in the first pixel element during a first accumulation period, and a second image signal based on signal charge generated in the second pixel element during a second accumulation period longer than the first accumulation period, the second image signal being synchronized with the first image signal, and a control unit configured to control the readout circuit so that a first readout period for reading out the first image signal is performed during the second accumulation period.
