名称及摘要

电影编码方法以及动态图像解码方法
电影编码装置包括运动补偿编码单元(107)决定编码模式编码电流被编码块以及用于产生预测图象数据基于编码模式,而且一种直接模式启动/禁止判断装置(109),用于判断是否缩放处理可以进行当编码方式决定运动补偿编码单元(107)是临时直接模式。 当判断出缩放处理可以不可以进行,运动补偿编码单元(107)执行运动补偿任一,通过利用另编码方式或不缩放处理。
Moving picture encoding method and motion picture decoding method
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.
