To allow highly efficient encoding with respect to a moving picture which changes in luminance over time, e.g. a fade image or dissolving image.
A variable length decoder 303 decodes encoded data 300 including a predictive error signal representing an error of a predictive picture signal with respect to a moving picture signal including a luminance signal and two color difference signals, motion vector information 414, at least one reference picture number, and index information 415 representing a combination of predictive parameters prepared in advance by luminance signal and the two color difference signals, and a frame memory/predictive picture generating unit 308 generates a predictive picture signal 412 in accordance with the reference picture number and predictive parameters of the combination denoted by the decoded index information and generates a reproduction picture signal by using the predictive error signal and the predictive picture signal.
