Abstract:
Methods, systems, and computer programs for improving compressed image chroma information. In one aspect of the invention, a resolution for a red color component of a color video image is used that is higher than the resolution for a blue color component of the color video image. Another aspect includes utilizing a lower or higher value of a quantization parameter (QP) for one or more chroma channels as compared to the luminance channel. Another aspect is use of a logarithmic representation of a video image to benefit image coding. Another aspect uses more than two chroma channels to represent a video image.

Claim (Index 6):
The method of  claim 5 , further comprising:\n receiving, at the decoder, at least a second image-region-dependent chroma QP bias value, the second image-region-dependent chroma QP bias value was determined at the encoder and signaled from the encoder to the decoder; utilizing, with the decoder, the luminance QP value and the second image-region-dependent chroma QP bias value to determine the second chroma QP value by adding the second image-region-dependent chroma QP bias value to the luminance QP value; and decompressing the image region of the video image using at least the second chroma QP value, wherein the second chroma QP value is determined for the second chroma channel, and wherein the first image-region-dependent chroma QP bias value used to determine the first chroma QP value for the first chroma channel differs from the second image-region-dependent chroma QP bias value used to determine the second chroma QP value for the second chroma channel.
