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 5):
A method comprising:\n receiving, at the decoder, at least a luminance QP (quantization parameter) value and a first image-region-dependent chroma QP bias value, the first image-region-dependent chroma QP bias value was determined at an encoder and signaled from the encoder to the decoder, wherein the decoder comprises a luminance channel, a first chroma channel and a second chroma channel; utilizing, with the decoder, the luminance QP value and the first image-region-dependent chroma QP bias value to determine the first chroma QP value by adding the first image-region-dependent chroma QP bias value to the luminance QP value; decompressing an image region of a video image using the luminance QP value and the first chroma QP value, wherein the first chroma QP value is less than a predetermined maximum value and greater than a predetermined minimum value, and wherein the first chroma QP value is determined for the first chroma channel.
