ABSTRACT:
An improved motion estimating method serves to determine a set of target motion vectors between a current frame and its previous selected frame, wherein N number of frames are skipped between the current frame and the previous selected frame, said N being a positive integer inclusive of 1. This method is implemented through the use of all frames, i.e., the current and the previous selected frames and the N number of skipped frames in order to obtain a series of motion vectors for one of the search points within the previous selected frame. Said series of motion vectors is then summed up to define a target motion vector representing the displacement between said one of the search points and the corresponding best matching point in the current frame. The process is repeated until the set of target motion vectors for all of the search points contained in the previous selected frame are detected.
