Abstract
A photoelectric convertor is provided. The convertor includes first and second pixels each including an avalanche photodiode and a counter, and a processor. The first and second pixels repeat a detection operation including exposure intervals in which the counter counts a number of times that an avalanche breakdown occurred in the photodiode and holding intervals in which a count value counted in the exposure interval is held in the counter. After a predetermined time has elapsed from the start of a first exposure interval of the first pixel, a second exposure interval of the second pixel is started. The processor outputs a difference value between a first count value counted in the first exposure interval and held in the counter in a first holding interval that continues from the first exposure interval and a second count value counted in the second exposure interval.
