<P>PROBLEM TO BE SOLVED: To reduce computational complexity and an increase in overhead of coded data as to a fade image, and to considerably improve the predictive efficiency. <P>SOLUTION: In carrying out motion compensation predictive inter-frame coding to a coding object block in a coding object frame of a moving picture by using a plurality of reference frames with a prescribed combination and a motion vector between the coding object block and at least one reference frame, the moving picture coding apparatus determines weighting factors and a DC offset value, computes a linear sum by using the weighting factors as to a plurality of reference blocks extracted from the reference frames and adds the DC offset value to the linear sum to produce a predictive block, produces a predictive error signal between a predicted block and the coding object block, and codes respective information items such as the predictive error signal, the reference frames, weighting factors, the DC offset value and the motion vector. <P>COPYRIGHT: (C)2007,JPO&INPIT |
