Further, the method includes performing, in a dequantization unit in the image decoding apparatus, dequantization on the luma component of quantized coefficients using the luma quantization parameter and the chroma component of quantized coefficients using a chroma quantization parameter calculated on the basis of the luma quantization parameter weighted by an add operation of the weight parameter. In addition, the method includes performing, in a transform unit in the image decoding apparatus, an inverse orthogonal transform.

Abstract: The present disclosure relates to an image processing device and method that enable efficient decoding of a picture partitioned into tiles. Upon being supplied with a tile initial QP from a tile initial QP buffer, a differential QP generation unit acquires a picture initial QP by sending a request to a picture initial QP buffer. The differential QP generation unit generates a differential QP between the picture initial QP and the tile initial QP, and supplies the generated differential QP to a syntax setting unit 161. The syntax setting unit sets the differential QP between the picture initial QP and the tile initial QP, near the beginning of the corresponding tile in an encoded stream, as the initial value of the quantization parameter for the tile (TILE_int_QP). The present disclosure is applicable to, for example, an image processing device.
