<P>PROBLEM TO BE SOLVED: To provide an apparatus and corresponding method for fast motion estimation with multiple reference pictures. <P>SOLUTION: An exemplary video encoder (100) for encoding video signal data for an image block relative to multiple reference pictures includes a fast motion estimator (180) for providing motion vectors corresponding to one of reference pictures, including a scene detection portion for performing fast motion estimation while excluding reference pictures that fall across a scene change. A corresponding method (200) for encoding video signal data for an image block having multiple reference pictures includes receiving (210) a substantially uncompressed image block, detecting (215) a scene change, excluding (225) reference pictures that fall across the scene change, and computing (235) motion vectors corresponding to a difference between the image block and one of the multiple reference pictures. <P>COPYRIGHT: (C)2012,JPO&INPIT |
