| 20090067501 | DYNAMIC IMAGE ENCODING DEVICE, DYNAMIC IMAGE DECODING DEVICE, DYNAMIC IMAGE ENCODING METHOD, DYNAMIC IMAGE DECODING METHOD, DYNAMIC IMAGE ENCODING PROGRAM, AND DYNAMIC IMAGE DECODING PROGRAM - A moving image encoding device measures a band of a target image to be encoded and a band of a reference image by a band analyzer, and generates band-related information representing these bands. A prediction signal generator generates a prediction signal such that the signal matches the band of the target image, from the reference image, based on the band-related information. A difference unit obtains a difference between the target image and the prediction signal to generate a differential signal. A converter and a quantizer each encode the differential signal to generate an encoded differential signal. An inverse quantizer and an inverter each decode the encoded differential signal to generate a decoded differential signal. An adder adds the prediction signal to the decoded differential signal to generate a reproduced image. An output terminal outputs at least the encoded differential signal and the band-related information. | 03-12-2009 |
