Abstract
The present invention relates to a method and apparatus for removing unwanted movements in digitized image caused by unsuitable camera mountings or recordings made under difficult conditions. The image data is processed by tracking a selected image portion over a plurality of frames. The position of the image within its frame is adjusted so that the position of the selected image portion remains substantially constant frame after frame, and modifications to the image are made. Portions of the images that extend beyond frame edges are repositioned within the frame edge. The position of the image within its frame is then reset to its original position, so that the modified image moves as if it were part of an original shot.
