Abstract: An image enhancement method, comprising: obtaining a reference image frame from of a scene, by a frame-based sensor, wherein the reference image contains artifacts and has an exposure duration; obtaining a stream of events, by an event-based sensor which is synchronized with the frame-based sensor, at least during the exposure duration, wherein the events encode brightness changes of the scene corresponding to the reference image; and deriving a corrected image frame without the artifacts from the reference image frame using the stream of events.
