<p><P>PROBLEM TO BE SOLVED: To efficiently encode a moving picture having luminance changing timewise, such as fade and dissolve images. <P>SOLUTION: A variable length decoder 303 decodes coding data 300 including a predictive error signal indicating an error of a predictive image signal to a moving picture signal having a luminance signal and two color difference signals, motion vector information 414, and index information 415 indicating a combination of at least one reference image number and a predictive parameter prepared in advance for each of the luminance signal and the two color difference signals. A frame memory/predictive image generator 308 generates a predictive image signal 412 according to the reference image number and predictive parameter of a combination indicated by the decoded index information, and uses the predictive error signal and the predictive image signal to generate a reproduction moving picture signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
