ABSTRACT:
A photoelectric converting apparatus having an accumulating device to accumulate a signal from a photoelectric converting device. This apparatus includes a first accumulating portion to accumulate a readout signal of the photoelectric converting device; and a second accumulating portion to accumulate the remaining signal after the photoelectric converting device was refreshed, wherein the signals of the first and second accumulating portions are superposed and output, thereby obtaining an output signal in which the remaining signal is eliminated from the readout signal.
