  • Publication number: 20220070392
    Abstract: The present technology relates to an event signal detection sensor and a control method for shortening latency and reducing overlooking objects. A plurality of pixel circuits detects an event that is a change in an electrical signal of a pixel that generates the electrical signal by performing photoelectric conversion, and outputs event data indicating the occurrence of the event. A detection probability setting unit calculates a detection probability per unit time for detecting the event for each region formed with one or more pixel circuits, in accordance with a result of pattern recognition. The detection probability setting unit controls the pixel circuits in such a manner that event data is output in accordance with the detection probability. The present technology can be applied to an event signal detection sensor that detects an event that is a change in an electrical signal of a pixel.
