Abstract  Abstract

The invention claims an image quantization parameter encoder includes a prediction unit for reconstructing the quantized from a previous parameter to generate the prediction quantization parameter a calculating unit for the prediction quantization parameter from the quantization parameter and generate a difference quantization parameter and a quantization parameter coding unit. for indicating the absolute value difference quantization parameter whether a meaning of the first binary bit indicating poor quantization parameter under the condition the significance difference quantization parameter with other binary bits and quantization parameter indicating a difference is positive or negative sign binary bit by binary arithmetic coding other binary bits after the first binary bit signed binary bit after the other binary bit wherein the binary arithmetic coding is used for first binary bit and other binary bit context and unused for the context of the binary bit is executed and wherein the binary arithmetic coding is used for the first binary bit of the first context and for other binary bits is performed with different context of the first context of use.
