A driving method for an image pickup apparatus includes accumulating a signal generated during a first charge accumulation period by a first sub pixel, accumulating a signal generated during a second charge accumulation period partially overlapped with the first charge accumulation period by a second sub pixel, and controlling column circuits such that, after processing of the signal generated during the first charge accumulation period is performed, processing of the signal is performed which is generated during the second charge accumulation period of the second sub pixel included in the pixel where the signal processing of the first sub pixel is performed, and the column circuits are put into a non-operating state during at least part of a period after the processing of the signal generated during the first charge accumulation period is ended until the second charge accumulation period is ended.
