Abstract:
1. A moving image encoding device, comprising: input means for inputting an input image as an encoding target; reference image accumulation means for accumulating a reference image; reference image accompanying information accumulation means for accumulating reference image accompanying information that accompanies the reference image; encoding means 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; output means 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; image reverse modification means for reverse-modifying a locally decoded image that has been locally decoded by the encoding means; and reference image accompanying information reverse modification means for reverse-modifying information that accompanies the locally decoded image output by the encoding means, wherein the reference image accumulation means accumulates information that has been reverse-modified by the image reverse modification means as the reference image; and the reference image accompanying information accumulation means accumulates information that has been reverse-modified by the reference image accompanying information reverse modification means as the reference image accompanying information.
