Abstract
Apparatus ( ) for compensating for jitter in a digital image forming part of a video sequence of such digital images includes a first motion estimation unit ( ) having an input for receiving sensed image data and an output for providing a first plurality of motion vectors, each corresponding to one of a plurality of image blocks making up the digital image. A jitter estimation unit ( ) determines a jitter vector from the first plurality of motion vectors for the digital image and a jitter compensation unit ( ) adjusts the digital image using the jitter vector to compensate for jitter in the digital image. A second motion estimation unit ( ) provides a second plurality of motion vectors, each corresponding to one of a plurality of image blocks making up the jitter compensated digital image. The second plurality of motion vectors are determined by utilizing the first plurality of motion vectors and the jitter vector. The second plurality of motion vectors can be used in coding the jitter compensated image for storage and/or onward transmission.
