Photoelectric conversion device, movable apparatus, photoelectric conversion method, and storage medium

A photoelectric conversion method of performing photoelectric conversion in a plurality of pixels each including a sensor portion configured to emit a pulse corresponding to an incident photon, a counter configured to count the number of pulses, and a memory configured to store a count value of the counter, the photoelectric conversion method comprising:

• generating a signal based on a difference in the count value of the counter between at a start timing and at an end timing of an accumulation period;
• and
• outputting the signal generated in a first accumulation period between an end of the first accumulation period and an end of a second accumulation period, the first accumulation period and the second accumulation period being included in a full frame period, the first accumulation period being shorter than the second accumulation period.

A non-transitory computer-readable storage medium configured to store a computer program comprising instructions for executing a photoelectric conversion process of performing photoelectric conversion in a plurality of pixels each including a sensor portion configured to emit a pulse corresponding to an incident photon, a counter configured to count the number of pulses, and a memory configured to store a count value of the counter, the photoelectric conversion process comprising:

• generating a signal based on a difference in the count value of the counter between at a start timing and at an end timing of an accumulation period;
• and
• outputting the signal generated in a first accumulation period between an end of the first accumulation period and an end of a second accumulation period, the first accumulation period and the second accumulation period being included in a full frame period, the first accumulation period being shorter than the second accumulation period.
