Signal band when moving picture encoding and decoding is to efficiently compress a moving image to the other image are mixed. The video encoding device 13 measures a band of the band of the target image and the reference image of the encoding by the spectrum analyzer 10, and generating band-related information representing these bands. Prediction signal generator 9 generates a prediction signal from the reference image on the basis of the band-related information, to fit the band of the target image. The difference calculator (2) to generate a difference signal, obtain a difference between the target image and the prediction signal. Converter 3 and a quantizer 4 generates an encoded difference signal and encoding the difference signal. The inverse quantizer 5 and the inverse converter (6) decodes the encoded difference signal to generate a decoded differential signal. The adder 7 adds the prediction signal to the decoded differential signal to generate a reproduced image. Output terminal 12 outputs at least the encoded differential signal and the band-related information. ; A moving picture, encoding, decoding, quantizer, contrast
