摘要： A dynamic vision sensor may include a pixel array including at least a first photoreceptor and a second photoreceptor, the first photoreceptor and the second photoreceptor including at least one first pixel and at least one second pixel, respectively, the at least one first pixel and the at least one second pixel configured to generate at least one first photocurrent and at least one second photocurrent in response to an incident light, respectively, and the first photoreceptor and the second photoreceptor configured to a first and second log voltages based on the at least one first photocurrent and the at least one second photocurrent, respectively, processing circuitry configured to, amplify the first and second log voltages, detect a change in intensity of the light based on the amplified first log voltage, the amplified second log voltage, and a reference voltage, and output an event signal corresponding to the detected value.
