Abstract
A device includes a conversion unit, a generation unit configured to generate a pulse signal based on a signal from the conversion unit, a counter circuit configured to count the generated pulse signal, and a time measurement circuit configured to measure a time wherein one of a count value counted by the counter circuit or a time measurement value measured by the time measurement circuit is selectively output.
Claims6
A photoelectric conversion device, comprising:
- a first pixel circuit including:
- a first photoelectric conversion unit;
- a first generation unit configured to generate a pulse signal based on a signal from the first photoelectric conversion unit;
- and
- a first counter circuit configured to count the generated pulse signal;
- and
- a second pixel circuit including:
- a second photoelectric conversion unit;
- a second generation unit configured to generate a pulse signal based on a signal from the second photoelectric conversion unit;
- a second counter circuit configured to count the generated pulse signal;
- and
- a time measurement circuit configured to measure a time,
- wherein the first pixel circuit does not include a time measurement circuit, and
- wherein the second pixel circuit selectively outputs one of a count value counted by the second counter circuit or a time measurement value measured by the time measurement circuit.
