Abstract
In a photoelectric conversion apparatus including a plurality of pixels arranged in a matrix, each pixel including a photoelectric conversion unit, first and second holding units that hold electric charge, a first transfer unit that connects the photoelectric conversion unit and the first holding unit, a second transfer unit that connects the first and second holding units, and a third transfer unit that connects the photoelectric conversion unit and a power supply, each pixel is controlled so that the potential of the third transfer unit for electric charge held in the photoelectric conversion unit is higher than that of the first transfer unit at least during a charge accumulation period of the pixel, and thereafter, the potential of the third transfer unit is higher than that of the photoelectric conversion unit while the potentials of the first and second transfer units are lower than that of the photoelectric conversion unit.
