Encoding system for motion compensation
专利汇可以提供Encoding system for motion compensation专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce the deterioration in picture quality and to perform encoding of high compressibility by detecting a scene change in which the content of a screen is remarkably changed and no correlation of the screen exists, and setting a motion vector which represents a motion at a regulated value when the scene change is detected.
CONSTITUTION: A delay circuit 1 delays and adjusts an inputted animation signal 101 and supplies it to a vector detector 3 and a subtractor 4. The vector detector 3 detects a motion vector 103 which represents the motion from the animation signal supplied from the delay circuit 1 and supplies it to a variable delay frame memory 7 and a variable length encoder 8. Also, when the scene change is generated, the vector detector 3, corresponding to a scene change signal 102 supplied from a scene change detector 2, sets the motion vector 103 at a regulated value regulated in advance, for example, zero and performs actually an inter-frame estimation. Therefore, it is evaded that the motion compensation is performed by an erroneous motion vector and excessive information is generated.
