A photoelectric conversion apparatus comprising:
- a plurality of pixels, each of the plurality of pixels including a photoelectric conversion unit arranged in columns and rows and each configured to generate an electrical charge;
- a plurality of digital signal generation units arranged in columns and rows and each configured to generate a digital signal based on the electrical charge;
- and
- a control unit,
- wherein the plurality of digital signal generation units generates a first digital signal during a first period in a case where a predetermined event does not occur, and
- wherein the control unit controls the plurality of digital signal generation units to generate a second digital signal in a second period longer than the first period in a case where the predetermined event occurs.
