IMAGE CODING APPARATUS, METHOD FOR CODING IMAGE, PROGRAM THEREFOR, IMAGE DECODING APPARATUS, METHOD FOR DECODING IMAGE, AND PROGRAM THEREFOR
摘要:
An image coding method for dividing an input image into a plurality of divisional blocks having different sizes, and coding the image for each of the divisional blocks includes acquiring attribute information of a target block, setting a control parameter for controlling an image quality of the target block, determining a prediction control parameter based on the attribute information, calculating a difference value between the control parameter and the prediction control parameter, and coding the calculated difference value.
