Abstract

A photoelectric conversion device includes a photodiode configured to perform avalanche multiplication, a recharging circuit configured to perform a recharging operation to bring the photodiode after the avalanche multiplication into a state in which the avalanche multiplication can be performed again based on a first control signal including pulses that periodically repeat transitions from a first level to a second level, and a counter configured to count the number of occurrences of the avalanche multiplication by being enabled based on a second control signal. Before the counter is enabled based on the second control signal, the first control signal transitions from the first level to the second level and transitions from the second level to the first level.
