ABSTRACT:
A value of a selection parameter is sequentially set from among a plurality of parameters included in a modeling equation to derive a quantization matrix. A value of each of the parameters is sequentially derived based on a code amount and an encoding distortion obtained from an encoding using a quantization matrix generated from an updated parameter set.
