Title:
PHOTODETECTION DEVICE, DISTANCE MEASUREMENT DEVICE, AND METHOD FOR CONTROLLING PHOTODETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/084792
Kind Code:
A1
Abstract:
The present invention reduces the circuit area in a photodetection device in which a plurality of pixels are arranged. A first detection circuit detects the incidence of photons on the basis of the voltage of one of the anode and cathode of a first photoelectric conversion element during a period that is not a predetermined detection halt period. A second detection circuit detects the incidence of photons on the basis of the voltage of one of the anode and cathode of a second photoelectric conversion element during a period that is not the detection halt period. A shared circuit controls the voltage of a gating pulse indicating the detection halt period.
