Abstract
An image processing apparatus and a method for processing an image. The image processing apparatus includes circuitry configured to set a current quantization parameter for a current coding block in a layer lower than a layer of a largest coding block and a quantization parameter based on a difference between the current quantization parameter for the current coding block and a slice quantization parameter for a slice in which the current coding block is located. The circuitry quantizes image data to generate quantized data based on the current quantization parameter. Further, the circuitry codes the generated quantized data in a coding block including a hierarchical structure to generate a code data including the quantization parameter.
