Abstract  Abstract

An image quantization parameter encoder is provided with: a predictor (11) for generating a predicted quantization parameter from a past reconstructed quantization parameter; a calculator (12) for generating a differential quantization parameter from a quantization parameter and the predicted quantization parameter; and a quantization parameter encoder (13) which, when the differential quantization parameter is significant, performs binary arithmetic encoding of a first bin indicative of whether the differential quantization parameter is significant, a different bin indicative of the absolute value of a non-redundant differential quantization parameter, and a bin indicative of the positivity/negativity of the differential quantization parameter.
