TRANSFORMATION CODING DEVICE |
摘要 |
<p>Disclosed is a transformation coding device which applies high 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 in accordance with statistical properties of an input signal to be implemented, and at the same time, allowing a signal to be efficiently compressed.</p> |
