1. A photoelectric conversion apparatus comprising:
a plurality of pixel circuits;
a plurality of A/D conversion circuits configured to generate digital data by A/D-converting, during an A/D conversion period, analog signals read out from the plurality of pixel circuits;
a plurality of memory circuits configured to store the digital data generated by the plurality of A/D conversion circuits;
a plurality of output circuits each connected to at least two memory circuits among the plurality of memory circuits; and
a scanning circuit configured to select one of the plurality of output circuits, and select one of the at least two memory circuits connected to the selected output circuit, thereby reading out, to an output line, the digital data stored in the selected memory circuit,
wherein the scanning circuit is configured not to change the selection of the output circuit from the plurality of output circuits during a prohibition period including at least a period until 0.65T elapses after a lapse of 0.35T since a start of the A/D conversion period where T represents a length of the A/D conversion period.
