Image coding method for motion picture expert groups, involves image quantizing data in accordance with quantization parameter, and coding entropy of quantized image data using entropy coding unit
The method involves modeling image quality distribution of an input image in units of scenes. A quantization parameter of each region constituting the scene is determined according to the result of modeling. The image data is quantized according to the quantization parameter. Entropy of the quantized image data is coded by using entropy coding unit (160). - Independent claims are also included for the following: - (a) an image coding apparatus - (b) an image decoding method - (c) an image decoding apparatus.
