Photoelectric conversion element and imaging device

A photoelectric conversion element comprising a plurality of pixels arranged to receive a light and each including a photoelectric converter that generates a charge in response to incidence of a light,

• wherein the plurality of pixels includes:
• a first pixel configured to perform a first readout operation to read out a reset signal based on the photoelectric converter in a reset state and an optical signal based on a charge generated by the photoelectric converter;
• and
• a second pixel that is a pixel on which a readout operation is performed at the same time as that of the first pixel and is configured to perform selectively either one of the first readout operation to read out the reset signal and the optical signal, and a second readout operation to read out the reset signal without reading out the optical signal,
• wherein each of the plurality of pixels further includes a reset transistor that resets the photoelectric converter,
• wherein the photoelectric conversion element further comprises a control unit that controls the reset transistor of each of the plurality of pixels, and
• wherein the control unit controls the reset transistor of the second pixel to be selectively turned on and resets the photoelectric converter of the second pixel after simultaneously reading out reset signals from the plurality of pixels and before simultaneously reading out optical signals from the plurality of pixels.

• wherein a control line that controls the first switch of the first pixel and a control line that controls the first switch of the second pixel are formed of the same wiring, and
• wherein a control line that controls the second switch of the first pixel and a control line that controls the second switch of the second pixel are formed of different wirings.
