Abstract
A photoelectric conversion device includes pixels each including a photoelectric conversion unit for generating charge by photoelectric conversion, first to fourth charge holding portions configured to be transferred charge from the photoelectric conversion unit, and an output unit for outputting a signal corresponding to charge transferred from one of the first to fourth charge holding portions, and a control circuit for controlling the plurality of pixels. The control circuit performs, during one frame, transferring charge in the photoelectric conversion unit to the first or second charge holding portion a plural times for each of the first and second charge holding portions in each of the pixels at the same time, and performs, during the one frame, reading out from each pixel a signal corresponding to charge in the third charge holding portion and a signal corresponding to charge in the fourth charge holding portion.
