ABSTRACT:
A transformation coding device which applies high by efficient coding to a digital image signal, and in which a plurality of quantization characteristics are prepared and one quantization characteristic is adaptively selected in accordance with a predicted distortion for an input signal and a sequence of transformation coefficients, thereby allowing the quantization to be performed in accordance with statistical properties of an input signal to be implemented, and at the same time, allowing a signal to be efficiently compressed.
