摘要 |
An image decoding method for decoding a bit stream in an image decoding apparatus. The decoding process includes receiving the bit stream and a chroma quantization parameter calculated on the basis of a luma quantization parameter weighted by an addition operation; decoding, in a decoding unit in the image decoding apparatus, the bit stream and generating a chroma component of quantized coefficients; and performing, in a dequantization unit in the image decoding apparatus, dequantization on the chroma component of quantized coefficients using the chroma quantization parameter calculated on the basis of a luma quantization parameter weighted by an addition operation.
