摘要： A decoding method decodes a bit stream in an image decoding apparatus. The method includes receiving a weight parameter that is added to a luma quantization parameter as the bit stream. The method also includes decoding, in a decoding unit in the image decoding apparatus, the bit stream, and generating a luma component of quantized coefficients and a chroma component of quantized coefficients. 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.

摘要： An image processing method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes detecting a condition that a reference field has a different parity from a current field and that the number of chroma pixels is vertically different from the number of luma pixels. The method further includes shifting a phase of the chroma signal in the reference field in a vertical plus direction according a value of a motion vector in a vertical direction under the detected condition so that the reference field will coincide in phase of the chroma signal with a current field. The method also includes performing a motion compensation of the decoded image signal using the reference field.
