Abstract:
An object of the present invention is to encode and decode image information more efficiently by generating an appropriate predictive signal.The image encoding device of the present invention comprises an input section 201 for inputting an input image constituting an encoding target; a reference image accumulation section 202 for accumulating a reference image; a reference image accompanying information accumulation section 203 for accumulating reference image accompanying information which accompanies the reference image; an encoding section 206 for modifying the reference image and the reference image accompanying information in accordance with the input image, generating a predictive signal for the input image, and encoding the input image; and an output section 209 for outputting, as encoded data, compressed data obtained by encoding by the encoding means together with modification method information indicating a modification method for the reference image.
