<p><P>PROBLEM TO BE SOLVED: To enable high efficient encoding for a moving image having luminance changing in time, such as a fade image or a dissolve image. <P>SOLUTION: A variable length decoder 303 decodes encoded data 300 including a predictive error signal indicating an error of a predictive image signal for a moving image 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 previously prepared 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 in accordance with the reference image number and the predictive parameter of the combination indicated by the decoded index information, and generates a reproduced moving image signal by using the predictive error signal and the predictive image signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
