An image pickup apparatus according to the present invention includes a plurality of pixels arranged in rows and columns, and each of the pixels includes a photoelectric conversion unit that accumulates signal charge generated by photoelectric conversion of irradiated light, a first holding unit and a second holding unit that hold the signal charge transferred from the photoelectric conversion unit, and an output unit that outputs, to a column signal line, a signal based on an amount of the signal charge held by the first holding unit or the second holding unit. The first holding unit and the second holding unit alternately hold the signal charge generated in the photoelectric conversion unit for each frame period, and in a period in which the signal charge is not transferred from the photoelectric conversion unit, the first holding unit and the second holding unit output the signal charge to the output unit.
