ABSTRACT:
A method for motion estimation and for motion compensated interpolation. By taking a source of video data into account, a size of update vectors to be employed for determining spatial prediction vectors is set in accordance with a detected source mode. By selecting an appropriate update vector size, accuracy of predicted motion and consequently, a picture quality of motion compensated interpolated images can be increased considerably.
