<p><P>PROBLEM TO BE SOLVED: To efficiently encode moving pictures of which luminance changes with time, such as fade images and dissolving images. <P>SOLUTION: A variable length decoder 303 decodes encoded data 300. The encoded data 300 include: a predictive error signal indicating an error of a predictive image signal with respect 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 for each luminance signal and for each two color difference signals. A frame memory/predictive image generator 308 generates a predictive image signal 412 according to the reference image number in a combination indicated by the decoded index information, and the predictive parameter, 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> |
