<p>A motion compensation apparatus for receiving information on motion vectors and for performing a motion compensation of dynamic image signals with precision equal to or finer than one pixel. The information on motion vectors has been estimated from a reference field or frame represented by a reference field signal (2) or a reference frame signal and other fields or other frames represented by other field signals (1,3) or frame signals. The motion compensation apparatus is provided with a coefficient determination device (13) for determining resampling coefficients corresponding to signals which are generated by adding the other field (or frame) signals according to relations among the motion vectors (5,6) and image shifting devices (7,8) for resampling (9,10) and adding up (14) the field (or frame) signals by using the sampling coefficients to obtain image signals representing shifted pixels, which are motion-compensated (15) with precision that is equal to or finer than one pixel. <IMAGE></p> |
