摘要：
An image encoding device including an input section inputting an input image constituting an encoding target; a reference image accumulation section accumulating a reference image; a reference image accompanying information accumulation section accumulating reference image accompanying information that accompanies the reference image; an encoding section 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 outputting, as encoded data, compressed data obtained by the encoding by the encoding section together with modification method information indicating a modification method for the reference image. Thereby, image information can be encoded/decoded more efficiently by generating an appropriate predictive signal.
