Abstract
A photoelectric conversion device has a plurality of pixels each of which is configured to include a sensor unit that generates a pulse at a frequency corresponding to a photon reception frequency, and a counter that counts a number of the pulses. The plurality of pixels are controlled such that a signal is generated based on a difference between count values for the counter between a start time and an end time for a plurality of different accumulation periods within a full frame period, and such that an image signal that is generated during a first accumulation period is output between a time from an end of the first accumulation period until an end of a second accumulation period. In addition, the photoelectric conversion device generates a mapping parameter and performs tone mapping processing on the image signal using the mapping parameter.
