Abstract
There is provided a photodetection device capable of widening a dynamic range without increasing the number of photoelectric converters. The photodetection device according to an embodiment of the present disclosure includes a plurality of photoelectric converters arranged in one of pixels and configured to photoelectrically convert incident light. The plurality of photoelectric converters includes at least one first photoelectric converter and at least one second photoelectric converter having a lower sensitivity to the incident light than the first photoelectric converter.
Claims19
A photodetection device comprising
- a plurality of photoelectric converters arranged in one of pixels and configured to photoelectrically convert incident light, wherein
- the plurality of photoelectric converters comprises:
- at least one first photoelectric converter;
- and at least one second photoelectric converter having a lower sensitivity to the incident light than the first photoelectric converter.
A photodetection device comprising
- a plurality of photoelectric converters arranged in one of pixels and configured to photoelectrically convert incident light, wherein
- sensitivities of the plurality of photoelectric converters to the incident light are configured to be collectively decreased in a stepwise manner depending on a result of photoelectric conversions at the plurality of photoelectric converters.
A distance measuring system comprising:
- a photodetection device comprising a plurality of photoelectric converters arranged in one of pixels and configured to photoelectrically convert incident light, wherein the plurality of photoelectric converters comprises:
- at least one first photoelectric converter;
- and at least one second photoelectric converter having a lower sensitivity to the incident light than the first photoelectric converter;
- and
- a signal processing circuit that processes an output signal of the photodetection device.
A distance measuring system comprising:
- a photodetection device comprising a plurality of photoelectric converters arranged in one of pixels and configured to photoelectrically convert incident light, wherein sensitivities of the plurality of photoelectric converters to the incident light are configured to be collectively decreased in a stepwise manner depending on a result of photoelectric conversions at the plurality of photoelectric converters;
- and
- a signal processing circuit that processes an output signal of the photodetection device.
