摘要： A photoelectric conversion apparatus includes a photoelectric conversion element including a pixel area where a plurality of pixels composed of avalanche photodiodes for photoelectrically converting an optical image is two-dimensionally arranged, the photoelectric conversion element being configured to simultaneously read signals from a first pixel group and a second pixel group in the pixel area, generation means configured to generate an image based on the read signals, and correction means configured to perform a correction process on the image using correction information based on characteristic information regarding crosstalk between the plurality of pixels. The correction means differentiates the correction information between the first and second pixel groups.
