MOTION PICTURE ENCODING METHOD AND MOTION PICTURE DECODING METHOD

摘要

The moving picture coding apparatus includes a motion compensation coding unit (107) for deciding a coding mode for coding a current block to be coded and for generating predictive image data based on the coding mode; and a direct mode enable/disable judgment unit (109) for judging whether or not scaling processing can be performed when the coding mode decided by the motion compensation coding unit (107) is a temporal direct mode. When it is judged that the scaling processing cannot be performed, the motion compensation coding unit (107) performs motion compensation either by using another coding mode or without the scaling processing.
