Title:
EVENT DETECTION PIXEL CIRCUIT, EVENT IMAGE SENSOR AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/231405
Kind Code:
A1
Abstract:
Provided in the present disclosure are an event detection pixel circuit, an event image sensor and an electronic apparatus. The event detection pixel circuit comprises: a single-photon avalanche diode, a data generation unit, a data register unit, and a comparison unit, wherein the single-photon avalanche diode is configured to detect optical signals and output electrical pulse signals; the data generation unit is configured to generate, on the basis of the counting of the electrical pulse signals which are output by the single-photon avalanche diode, first data corresponding to a light intensity; the data register unit is configured to register second data; and the comparison unit is configured to compare the first data with the second data, so as to output an event detection result.
