<p><P>PROBLEM TO BE SOLVED: To perform highly efficient encoding for moving images the luminance of which changes with time, such as a fade image and a dissolve image. <P>SOLUTION: Encoded data 300 including: a prediction error signal indicating the error of a predicted image signal for moving image signals having a luminance signal and two color difference signals; motion vector information 414; and index information 415 indicating the combination of at least one reference image number and a prediction parameter prepared for each of the luminance signal and the two color difference signals, are decoded by a variable length decoder 303. By a frame memory/predicted image preparing device 308, the predicted image signal 412 is generated according to the reference image number and the prediction parameter of the combination indicated by the decoded index information, and a reproducing moving image signal is generated using the prediction error signal and the predicted image signal. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
