Abstract
In a motion picture encoding system, which permits encoding of motion picture with high encoding efficiency and also permits improvement of the picture quality, priority orders are set preliminarily to obtain encoding matched to man's sight characteristics. Preferential high picture quality encoding of a picture portion attracting attention can be obtained by setting a high priority order for that portion. An optimum combination intra- and forward, rearward and bi-directional predictive inter-frame encoding pattern can be selected for every N frames by preliminarily collecting information of a motion picture sequence to be encoded.
