Claim:
1. A driving method for an image pickup apparatus that includes a plurality of pixels arranged in rows and columns, and a plurality of signal lines each being arranged corresponding to one of the columns of the plurality of pixels, the plurality of pixels including each of the plurality of effective pixels including a photoelectric conversion unit to perform a photoelectric conversion of incident light and an amplification transistor having an input node for inputting charges generated by the photoelectric conversion unit, and each of the plurality of reference pixels including an amplification transistor having an input node, the driving method comprising: a first operation of overlapping periods, without electrically connecting the input node of the amplification transistor in each of a first number of effective pixels among the plurality of effective pixels, to each other, each period being a period during which the amplification transistor in each of the first number of effective pixels outputs a signal to common one of the signal lines, and a second operation of:
