    摘要： A solid state image pickup apparatus for removing noise includes a plurality of photoelectric transducer cells, and first and second switch circuitry. Signal readout lines are provided for reading out signals from the plurality of transducer cells. A plurality of first capacitors, each connected to one of the signal readout lines through the first switch circuitry, are provided for selectively storing first signals read out through the signal lines and the first switch circuitry after a predetermined accumulation period. A plurality of second capacitors, each connected to one of the signal read out lines through the second switch circuitry, are provided for selectively storing second signals corresponding to dark current signals read out through the signal read out lines and the second switch circuitry. Output circuitry is provided for cancelling dark current signals included in all of the first signals by subtracting each second signal from a corresponding first signal, and for outputting all of the first signals from which the dark current signals are cancelled.
