1. An apparatus for a dynamic vision sensor, DVS, configured to detect changes of light impinging on a pixel array of the DVS, the apparatus comprising:
an actuator configured to change an optical path of the light relative to the pixel array of the DVS to cause the pixel array to detect one or more events resulting from the actuator changing the optical path of the light relative to the pixel array, wherein the actuator is configured to change the optical path in at least one predefined direction; and
a control circuit configured to
distinguish, based on the predefined direction, one or more noise events from one or more events detected by the pixel array resulting from the actuator changing the optical path in the predefined direction, and
adjust a sensitivity of one or more pixels of the pixel array to adjust the DVS based on the noise events.
