Abstract: A photoelectric conversion device capable of operations corresponding to the amplitude of a signal read out to a vertical signal line is disclosed. The device comprises a pixel that generates a signal via photoelectric conversion and a determination circuit that determines an amplitude of a signal read out from the pixel to a vertical signal line. A reset signal and a data signal are read out from the pixel. The determination circuit performs a first determination on the data signal while the pixel is being selected for reading out a signal and performs a second determination on the reset signal.

Abstract: A photoelectric conversion device including pixels arranged to form rows, a scanning circuit that performs scanning for sequentially outputting a signal from the pixel on a row basis, and a processing circuit that processes a signal output from the pixel. The processing circuit corrects, based on a first reset signal and a second reset signal based on a reset state of the pixel, an optical signal based on incident light. The scanning circuit performs scanning for outputting the optical signal and the first reset signal from the pixel by scans performed in different periods. The scanning circuit performs scanning for outputting the optical signal and the second reset signal from the pixel by a scan. The first reset signal, the second reset signal, and the optical signal are output from the pixel in a frame period in which signals to be used for generating a frame is output.
