<p>A novel apparatus, capable of improving the image quality, comprises a converter for converting the B frame into a converted frame having a second set of search blocks wherein both the B frame and the converted frame have an overlapping region; a first predictor for estimating a first displacement vector representing the displacement between the B frame and a first neighboring frame of the B frame, and for providing a first predicted frame signal for the B frame based on the first estimated displacement vector; a second predictor for estimating a second displacement vector representing the displacement between the converted frame and a second neighboring frame of the converted frame, and for providing a second predicted frame signal for the converted frame based on the second estimated displacement vector; a third predictor for generating a third predicted frame signal by averaging the first and the second predicted frame signals located in an area corresponding to the overlapping region; and a circuit, responsive to selection signals corresponding to the frame types of the first and the third predicted frame signals, for selectively generating either the first predicted frame signal or the third predicted frame signal. <IMAGE></p> |
