<p><P>PROBLEM TO BE SOLVED: To efficiently encode a moving image having temporally-changing luminance such as a fade image or a dissolved image. <P>SOLUTION: A variable-length decoder 303 decodes encoded data 300 including a predictive error signal representing an error of a predictive image signal with respect to a moving image signal having a luminance signal and two color difference signals, motion vector information 414, and index information 415 indicating 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/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 reproduction moving image signal by using the predictive error signal and the predictive image signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
