Original Abstract Submitted
A photoelectric conversion device includes: a pixel array including pixel circuits arranged in rows and columns, each of the pixel circuits being configured to output a pixel signal based on incident light; first and second processing circuits each including a data processing unit configured to process the pixel signal to generate data; an output pad; an output circuit configured to output the data to the outside of the photoelectric conversion device via the output pad; an event signal generation unit configured to generate an event signal indicating an occurrence of an event; and a first power supply control unit. The first power supply control unit controls a first power supply control target circuit of the first processing circuit to be set to any one of states including a first state and a second state in which power consumption is higher than the first state based on the event signal.
