Photoelectric conversion device

A photoelectric conversion device comprising:

• a pixel array including a plurality of pixels arranged to form a plurality of rows and a plurality of columns;
• a first output line and a second output line each arranged to correspond to one of the plurality of columns;
• and
• a correction value generation unit configured to generate a correction value used for black level correction of a signal output from the pixel array,
• wherein the pixel array includes a first region including consecutive rows among the plurality of rows and a second region including other consecutive rows among the plurality of rows, the second region being adjacent to the first region,
• wherein each row of the first region and the second region includes an effective pixel region configured to output a signal according to incident light by photoelectric conversion and a correction signal acquisition region configured to output a correction signal,
• wherein the first output line is connected to a pixel in the first region and is not connected to any pixel in the second region,
• wherein the second output line is connected to a pixel in the second region and is not connected to any pixel in the first region,
• wherein the second region includes a first pixel row and a second pixel row that is adjacent to the first region, and
• wherein the correction value generation unit generates a correction value used for black level correction of a signal output from a pixel of the first pixel row based on a first correction coefficient and the correction signal, and generates a correction value used for black level correction of a signal output from a pixel of the second pixel row based on a second correction coefficient different from the first correction coefficient and the correction signal.
