Abstract

See full text

An image processing apparatus and a method for improving the coding efficiency for a quantization parameter are provided. The method includes steps of setting a predicted quantization parameter for a current coding unit by using multiple quantization parameters which are set for multiple surrounding coding units located around the current coding unit which is target of coding processing, and setting a difference quantization parameter indicating a difference value between the quantization parameter which is set for the current coding unit and the predicted quantization parameter.
