Abstract:
1. An image processing apparatus for encoding image data while a coding unit, which is a unit having a hierarchical structure, is adopted as a processing unit, the image processing apparatus comprising: a predicted quantization parameter setting unit including circuitry configured to set, in a condition that a current coding unit is located at the front of a current largest coding unit, a quantization parameter of a coding unit located at the last of the largest coding unit immediately before as a predicted quantization parameter for the current coding unit; a difference quantization parameter setting unit including circuitry configured to set 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 which is set by the predicted quantization parameter setting unit; and a coding unit including circuitry configured to generate a bit stream by encoding the image data with the coding unit being adopted as the processing unit.
