1. An imaging device comprising:
a plurality of pixels each including a photoelectric conversion portion configured to accumulate an electric charge generated with incident light, a holding unit configured to hold the electric charge, an amplification unit configured to output a signal based on the electric charge, a first transfer switch configured to transfer the electric charge from the photoelectric conversion portion to the holding unit, and a second transfer switch configured to transfer the electric charge from the holding unit to the amplification unit; and an output line to which signals from the amplification units of the plurality of pixels are output, wherein the photoelectric conversion portion of each of at least some pixels of the plurality of pixels includes a plurality of accumulation regions electrically isolated from each other, wherein at a first time, the photoelectric conversion portions of the plurality of pixels start accumulating the electric charge, wherein from the first time to a second time, the first transfer switch of at least one pixel of the plurality of pixels is maintained in an off-state, and the photoelectric conversion portion of the at least one pixel accumulates an electric charge generated during a first period from the first time to the second time, wherein in the first period, the second transfer switches of the plurality of pixels are turned on in turns, and the amplification units of the plurality of pixels output signals in turns, wherein during at least a part of a second period from the second time to a third time, the holding unit of each of the plurality of pixels holds an electric charge generated during the first period in the photoelectric conversion portion and an electric charge generated during the second period in the photoelectric conversion portion, and wherein at the third time, the first transfer switches of the plurality of pixels are controlled to shift from an on-state to an off-state. |
