Claim Text:
1. A moving picture decoding device comprising: a processor; a decoding section executed by the processor to decode the encoded differential signal so as to produce a decoded differential signal; a prediction signal generation section executed by the processor to produce a first prediction signal with respect to the decoded differential signal; an adding section executed by the processor to add the first prediction signal to the decoded differential signal so as to produce a reproduction signal; a storage section operable to store the reproduction signal as a reference image referred to in producing a second prediction signal; and a reference image generation section executed by the processor to generate an observation matrix from a matrix composed of a plurality of pixel vectors, each of the pixel vectors in the matrix representing respective different pre-existing reference images stored in the storage section, to produce, based on the observation matrix, a new reference image, and to store the new reference image in the storage section, wherein the prediction signal generation section is executed by the processor to produce the second prediction signal using at least the new reference image.
