摘要: Device for encoding a DPCM image is provided. A smoothness test performed on an original at tester. linearly predicted value of the obtained linear predictor. switching part operates depending result test. difference between and quantized, encoded when satisfactory. corrected by using space self-likeness not The adaptive application existing prediction, prediction likeness permits to obtain better DPCM, improve compression efficiency.
