摘要：Methods, systems, and computer programs for improving compressed imagechroma 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 bluecolor component of the color video image. Another aspect includes utilizing a lower orhigher value of a quantization parameter (QP) for one or more chroma channels ascompared to the luminance channel. Another aspect is use of a logarithmic
representation of a video image to benefit image coding. Another aspect uses more thantwo chroma channels to represent a video image.
