Abstract
A photoelectric conversion device including a pixel configured to output a signal in response to incidence of a photon includes a first measurement unit configured to measure the signal output from the pixel, a second measurement unit configured to measure time until the signal measured by the first measurement unit reaches a first threshold, a first storage unit configured to store, as a first time, a result of the measurement by the second measurement unit at a first time point, a comparison unit configured to compare the first time stored in the first storage unit and a second time measured by the second measurement unit at a second time point later than the first time point, and an output unit configured to output a signal corresponding to a result of the comparison by the comparison unit.
