Document Type and Number:
WIPO Patent Application WO/2024/111356
Kind Code:
A1
Abstract:
[Problem] The present disclosure provides an optical element capable of performing analog computing using capacitance, and achieving further reduction in size, a computing method, and an electronic device. [Solution] Provided according to the present disclosure is an optical detection element comprising: a pixel that has a photoelectric conversion element for performing photoelectric conversion on incident light; a readout circuit that has a first capacitor capable of maintaining a potential corresponding to an electric charge generated by the photoelectric conversion; and a computing circuit capable of changing the number of times of readout of the potential of the first capacitor according to a computing coefficient, wherein the computing circuit reads out the reset potential of the first capacitor the aforementioned number of times, and reads out the photoelectric conversion potential of the first capacitor corresponding to the electric charge generated by the photoelectric conversion the aforementioned number of times.
