Abstract: A method of motion compensation in a camera may include deriving a motion signal representative of a motion of the camera, processing video frames of a video signal from an image sensor of the camera during a viewfinder mode to derive motion vectors between pairs of frames, and processing the motion signal with a number of combinations of gain and offset factors during the viewfinder mode. The method may also include determining combinations for producing threshold motion vectors, and applying the combination producing the threshold motion vectors for processing the motion signal during a still capture mode to produce a control signal for a motion compensating element for optics of the camera.
