Abstract

A photoelectric conversion device has an avalanche photodiode, and a counter counting and outputting the number of output signals from the avalanche photodiode until the number reaches the count number. An exposure time of the avalanche photodiode is controlled and a recharge cycle of the avalanche photodiode is controlled. Control is performed such that a ratio of the count number to the maximum number of times of recharging determined by a quotient obtained by dividing the exposure time by the recharge cycle is set to a first ratio in a first frame, and the ratio of the count number to the maximum number of times of recharging is set to a second ratio smaller than the first ratio in a second frame different from the first frame.
