1. A photoelectric conversion device comprising:
a pixel including a photoelectric conversion unit configured to output a pulse according to incidence of a photon, a counting unit including a plurality of counters each configured to count pulses output from the photoelectric conversion unit, and a calculation unit configured to perform calculation processing on a plurality of count values held by the plurality of counters; and
an output line connected to the pixel,
wherein the calculation unit outputs a determination value indicating a relationship between the plurality of count values, and
wherein the pixel outputs a pixel signal including the determination value to the output line.
