<p><P>PROBLEM TO BE SOLVED: To enable decoding corresponding to highly efficient encoding to a moving picture, where luminance changes timewise, such as fade images and dissolving images. <P>SOLUTION: A variable length decoder 303 decodes encoded data 300, including a prediction error signal indicating an error of a prediction image signal to a moving picture signal having a luminance signal and two color difference signals, motion vector information 414, and index information 415 showing a combination of at least one reference image number and predictive parameters prepared in advance for each of the luminance signal and the two color difference signals. A frame memory/prediction image making apparatus 308 generates a prediction image signal 412 according to the reference image number and the predictive parameters in a combination indicated by the decoded index information and generates a reproduction moving picture signal by the prediction error signal and the prediction image signal. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
