Abstract  Abstract

The image quantization parameter encoder includes a prediction unit (11) for generating a predictive quantization parameter from past reconstructed quantization parameters; An operation unit (12) for generating a differential quantization parameter from a quantization parameter and a predictive quantization parameter; And a first bin indicating whether or not the difference quantization parameter is significant is binary arithmetic-coded using the first context, and if the difference quantization parameter is significant, a sign bin indicating positive and negative quantization parameters of the difference quantization parameter A quantization parameter coding means 13 for performing binary arithmetic coding on the other bin indicating the absolute value of the differential quantization parameter using a context different from the first context when the difference quantization parameter is significant, , And the quantization parameter coding means 13 performs binary arithmetic coding using the same context for a predetermined bin and bin or bin after a predetermined bin when the other bin is binary arithmetic coded .
