Abstract
An image decoding apparatus for decoding a bit stream includes a decoding unit that decodes the bit stream and generates a chroma component of quantized coefficients. The image decoding apparatus also includes a dequantization unit that performs a dequantization on the chroma component of quantized coefficients using a chroma quantization parameter calculated on the basis of a luma quantization parameter weighted by an addition operation. Further, the image decoding apparatus includes a transform unit that performs an inverse orthogonal transform.
