Abstract
A photoelectric conversion apparatus comprising a pixel array and a signal processor is provided. The pixel array is configured to be operable in driving modes in which different signal readout methods are used. The signal processor comprises a selector configured to select, based on the driving mode set for each pixel among the driving modes, a first pixel group and a second pixel group from regions of the pixel array, which have been designated to generate a correction value, a correction value generator configured to generate the correction value in accordance with a first representative value based on signals read out from the first pixel group and a second representative value based on signals read out from the second pixel group, and a corrector configured to correct, based on the correction value, the signal read out from the pixel array.
