专利汇可以提供Moving picture encoder专利检索,专利查询,专利分析的服务。并且PURPOSE: To reduce the total generation code quantity of an encoding frame by selecting a moving vector out of candidate moving vectors so as to reduce encoding quantity, for which the variable length encoding of a moving vector predictive error value is executed.
CONSTITUTION: A candidate moving vector calculation circuit 21 calculates a candidate moving vector d1, for which a motion compensation predictive error is made minimum, from an input picture signal (a) and a referring picture signal (b). A moving vector select circuit 22 calculates the moving vector predictive error between each candidate vector d1 and a predictive moving vector (c) when the plural candidate moving vectors are calculated. Then, the candidate moving vector d1, for which the moving vector predictive error is minimum, is outputted as a moving vector (d) of an encoding block. Thus, the total generation code quantity of the encoding frame can be reduced.
