<p><P>PROBLEM TO BE SOLVED: To efficiently code moving pictures of which the luminance changes with respect to time, such as, fading and dissolving images. <P>SOLUTION: A variable length decoder 303 decodes coding data 300. The data include a predictive error signal, indicating an error of a predictive image signal to a moving picture signal including 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 of the luminance and two color difference signals, beforehand. A frame memory/predictive image generator 308 generates a predictive image signal 412, in accordance with a combination of the reference image number and the predictive parameter indicated by the decoded index information, and uses the predictive error signal and the predictive image signal, to generate a reproduced moving picture signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
