1. A photoelectric conversion apparatus comprising a pixel array in which a plurality of pixels are arranged in a matrix, and a signal processor configured to process a signal read out from the pixel array,
wherein the plurality of pixels are configured to be operable in a plurality of driving modes in which different signal readout methods are used, and
the signal processor comprises:
a selecting circuit configured to select, based on the driving mode set for each pixel among the plurality of driving modes, a first pixel group and a second pixel group among the plurality of pixels from regions of the pixel array, which have been designated to generate a correction value;
a correction value generation circuit 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 correcting circuit configured to correct, based on the correction value, the signal read out from the pixel array.
