Photoelectric conversion device, imaging system, and moving body with pixel signal correction

A photoelectric conversion device comprising:

• a plurality of effective pixels and a plurality of light shielded pixels which are arranged respectively in a plurality of rows and a plurality of columns;
• a plurality of vertical output lines;
• and
• a signal processing circuit,
• wherein in a period during which a pixel signal is output from a first light shielded pixel which is a first-row light shielded pixel among the plurality of light shielded pixels to a first vertical output line among the plurality of vertical output lines, a pixel signal is output from a second light shielded pixel which is a second-row light shielded pixel among the plurality of light shielded pixels to a second vertical output line among the plurality of vertical output lines, and
• wherein the signal processing circuit corrects effective pixel signals output from the effective pixels by using a correction signal obtained by performing filtering processing on the pixel signal from the first light shielded pixel and on the pixel signal from the second light shielded pixel,
• wherein the signal processing circuit, by using a first synthetic value obtained by weighting a correction signal obtained by performing filtering processing on pixel signals from a plurality of light shielded pixels in a channel and weighting a correction signal previously obtained by performing filtering processing on pixel signals from a plurality of light shielded pixels in the channel, corrects the effective pixel signals in the channel.
