IMAGING DEVICE AND IMAGING SYSTEM

摘要

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.

1. An imaging device comprising:
a plurality of pixels, each of the plurality of pixels including
a photoelectric conversion unit that generates charge by photoelectric conversion;a holding unit that holds the charge transferred from the photoelectric conversion unit; andan amplifier unit that outputs a signal based on the charge transferred from the holding unit, wherein the plurality of pixels is configured to 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 with a length different from the first exposure period, in the first exposure period, the photoelectric conversion unit accumulates the generated charge, and charge held by the holding unit is transferred from the holding unit 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, and in the period of accumulating the generated charge only in the photoelectric conversion unit in the second exposure period, the charge held by the holding unit is transferred from the holding unit to the amplifier unit.
