Coding device for moving picture signal
专利汇可以提供Coding device for moving picture signal专利检索，专利查询，专利分析的服务。并且PURPOSE: To attain coding accurately by using a picture element point used for evaluating a vector quantization coincident with the picture point used for the evaluation of moving compensation or using a picture point including it so as to minimize the distortion while applying vector quantization to a predicted error checked by the evaluation of moving compensation.
CONSTITUTION: In the vector quantization for reducing an approximated error, for example, an evaluation picture element such as dotted round marks in addition to round marks (evaluation picture element point of movement compensation) can be used. In this case, a VQ vector having minimized distortion is decided tentatively as to the round mark evaluation point coincident with the evaluation point of the movement compensation and a VQ vector minimizing the distortion as to the remaining evaluation points of dotted line marks under a condition is used as a true VQ vector. Thus, the distortion due to the vector quantization at picture element points coincident with the evaluation picture element points of the movement compensation is ensured and the distortion as to other points than the evaluation points of the moving compensation are minimized to improve the coding efficiency.
