Abstract  Abstract

The image quantization parameter encoder includes: a prediction unit 11 for generating predictive quantization parameters from past reconstructed quantization parameters; An operation unit 12 for generating a differential quantization parameter from the quantization parameter and the predictive quantization parameter; And when the differential quantization parameter is significant, a first bin indicating whether the differential quantization parameter is significant, a second bin indicating positive positive of the differential quantization parameter, and a value indicating an absolute value of the differential quantization parameter. And quantization parameter encoding means 13 for performing binary arithmetic coding on the outer bins.
