Original Abstract Submitted
a photoelectric conversion device includes a pixel array including at least one pixel region for which an exposure time is set, the at least one pixel region including a plurality of counting pixels each to output a pixel signal corresponding to a counted value of the number of photons incident during a given exposure time, and a control unit to control the exposure time of the pixel array. the at least one pixel region includes a detection unit to detect an event indicating a change in the pixel signals, and a selection unit to select one of the counting pixels included in the at least one pixel region as a first counting pixel connected to the detection unit. in a case where the event is detected, the control unit determines a length of the exposure time of the at least one pixel region.
