Original Abstract Submitted
A photoelectric conversion device includes: a light receiving unit configured to generate a light reception signal according to incident light by photoelectric conversion; a time-to-digital conversion unit configured to periodically perform an operation of outputting a time count value indicating an elapsed time from light emission of a light source device to input of the light reception signal every time a predetermined period elapses in one ranging period; and a comparison unit configured to output a comparison result based on a first time count value that is a time count value obtained from the time-to-digital conversion unit at a first time included in the one ranging period and a second time count value that is a time count value of a second time included in the one ranging period. The photoelectric conversion device performs processing based on the comparison result.
