Abstract
Embodiments of the present disclosure provide a dynamic vision sensor, a method, and a noise filtering circuit for a dynamic vision sensor (DVS). The noise filtering circuit is configured to receive a first request signal in response to a first event detected by one of a group of pixels of the DVS. Also, the noise filtering circuit is configured to trigger a timeframe in response to receiving the first request signal. Further, the noise filtering circuit is configured to receive a second request signal in response to a subsequent second event detected by one of the group of pixels. Also, the noise filtering circuit is configured to forward the second request signal to an arbitration logic if the second event is detected within the timeframe, and to block the second request signal from being forwarded to the arbitration logic if the second event is detected outside the timeframe.
