Claim:
1. A driving method for an image pickup apparatus including a plurality of pixel rows constituting a first pixel group including a plurality of first pixel rows and a second pixel group including a plurality of second pixel rows, each pixel row including a plurality of pixels, and each pixel including a photoelectric conversion unit, the driving method comprising: controlling a first period from a start of a reset operation, to be performed on photoelectric conversion units in a first pixel row among the plurality of first pixel rows, for starting an electric charge accumulation period in the photoelectric conversion units in the first pixel row until an end of reading of signals based on the electric charges in the respective photoelectric conversion units in the first pixel row from the first pixel row and a second period from a start of reset operation, to be performed on photoelectric conversion units in a second pixel row among the plurality of second pixel rows, for starting an electric charge accumulation period in the photoelectric conversion units in the second pixel row, the second pixel row being arranged adjacent to the first pixel row until an end of reading of signals based on the electric charges in the respective photoelectric conversion units in the second pixel row from the second pixel row during one frame period in a manner that the second period is started after the first period is ended; and resetting the respective photoelectric conversion units in the second pixel row during the first period before the reading of the signals from the first pixel row is ended, wherein the first pixel row includes an image pickup pixel, and the second pixel row includes a focus detection pixel.
