ABSTRACT:
A pixel unit in which a plurality of pixels shares an accumulating unit for temporarily accumulating charges accumulated in photoelectric conversion devices, is arranged so that a control unit of a photoelectric conversion apparatus is adapted, when an accumulated charge amount of a first photodiode exceeds a saturation charge amount, to effect control in accordance with a first operation to discharge excess charges to a floating diffusion FD, and adapted, when an accumulated charge amount of a second photodiode exceeds a saturation charge amount, to effect control in accordance with a second operation to discharge excess charges to a charge discharge area, thereby expanding a dynamic range.
