Abstract:
A method of compensating for jitter in a digital image forming part of a video sequence of such digital images, the method comprising the steps of:providing a first plurality of motion vectors each corresponding to one of a plurality of image blocks making up the digital image, determining a jitter vector from the first plurality of motion vectors for the digital image and from a second plurality of motion vectors provided for a previous digital image in the video sequence; adjusting the digital image using the jitter vector to compensate for jitter in the digital image to produce a jitter compensated digital image; providing a second plurality of motion vectors including the steps of, for each image block in the jitter compensated digital image, determining a corresponding best matching image block in the digital image; and utilizing the motion vector from the first plurality of motion vectors for the corresponding best matching image block and the jitter vector to determine a jitter-compensated motion vector for the image block in the jitter compensated digital image.
