に予測される。2. Description of the Related Art A conventional method is disclosed in Japanese Patent Application No. Hei 9-18725.
According to this technique, prediction is performed using a linear sum of arbitrary plural images having high prediction efficiency. For example, for the third frame in FIG. 4, it is possible to perform prediction using an image mixed with the linear sum of the first and fourth frames, and the sixth frame is similarly subjected to the linear sum with the fourth and seventh frames. It is possible to make predictions using the mixed image. However, in the conventional method, the ratio of the linear sum of a plurality of images when performing prediction is determined in advance. This is because the ratio of the linear sum is determined based on the distance between frames and the like, so if the third frame is predicted using the first and fourth frames so that the ratio of the linear sum is a: b, The sixth frame is likewise the fourth and seventh frames.
When a frame is used, the ratio of the linear sum is predicted to be a: b.
