Abstract:
1. A photoelectric conversion device comprising: a plurality of pixels; a driving supplemental element; a signal line to which the plurality of pixels and the driving supplemental element are connected; a driving unit which drives the plurality of pixels and the driving supplemental element; and an output circuit which processes a signal output to the signal line from a readout pixel selected by the driving unit and outputs the processed signal, each of the plurality of pixels including: the driving supplemental element including: wherein the driving unit drives the plurality of pixels and the driving supplemental element to, during a first period which is in a selection period for selecting the readout pixel, in the readout pixel, reset the first charge-voltage converter by the first reset unit and then output a noise signal corresponding to the voltage of the first charge-voltage converter from the first output unit to the signal line, and in the driving supplemental element, reset the second charge-voltage converter by the second reset unit and then output a noise signal corresponding to the voltage of the second charge-voltage converter from the second output unit to the signal line, and in a second period which follows the first period and which is in the selection period, stop output of the noise signal to the signal line from the second output unit in the driving supplemental element, and the noise signal output to the signal line from the first output unit in the readout pixel is transferred to the output circuit in the second period.
