Abstract

An image processing apparatus (100) and a method for processing an image. The image processing apparatus includes circuitry configured to decode coded data in a coding block including a hierarchical structure to generate quantized data. The circuitry sets, based on a difference value between a current quantization parameter for a current coding block and a slice quantization parameter for a slice in which the current coding block is located, the current quantization parameter for the current coding block in a layer lower than a layer of largest coding block. Further, the circuitry inversely quantized data based on the set current quantization parameter.
