    摘要: A circuit includes a selection circuit electrically coupled to pixels of a line of an event vision sensor. The selection circuit is configured to receive an activation signal from an active pixel of the line, generate an acknowledge signal in response to receiving the activation signal, and send the acknowledge signal to the pixels of the line. The circuit also includes a control circuit that is electrically coupled to a pixel having a largest distance to the selection circuit among the pixels of the line. The control circuit is configured to receive the acknowledge signal from the selection circuit, and generate a process-reading signal in response to receiving the acknowledge signal. The circuit also includes an interface circuit electrically coupled to the pixels of the line and configured to cause a reset of the selection circuit, the control circuit, and the pixels of the line after receiving the process-reading signal.
