<P>PROBLEM TO BE SOLVED: To provide encoding and decoding techniques for facilitating more accurate interpolation of a skipped video frame. <P>SOLUTION: Techniques are described for acquiring motion information indicating the motion of a skipped video frame based on a translating motion and at least one other motion parameter, and applying the motion information in order to interpolate the skipped video frame. The motion information indicates the motion on the basis of a motion model for modeling three or more motion parameters, for example, differently from a conventional two-parameter translating motion vector. More accurate motion information is generated inside a decoder for performing interpolation or transmitted by an encoder within one or more frames. In either case, the present techniques reduces the quantity of artifacts visible in the interpolated frame. <P>COPYRIGHT: (C)2012,JPO&INPIT |
