A method and apparatus for image stabilization takes an input image sequence including a plurality of frames (23), estimates frame-level motion vectors for each frame, and adaptively integrates the motion vectors to produce, for each frame, a motion vector to be used for image stabilization (7). A copy of the reference image of a frame is displaced by the corresponding adaptively integrated motion vector (21). In one embodiment, the perimeter of the image sensor is padded with margin to be used for image compensation. In another embodiment, vertical and horizontal components are treated independently (7). In still another embodiment, the motion estimation circuitry associated with an MPEG-4 encoder is used to calculate macroblock level vectors (11), and a histogram is used co compute a corresponding frame-level vector for that frame (7). |
