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 2):
A method comprising:\n receiving a compressed video image comprising a luminance channel (Y), a first chroma channel (V) and a second chroma channel (U); accessing, at the decoder, at least a luminance quantization parameter value; characterized by\n receiving a first image-region-dependent chroma quantization parameter bias value; \n utilizing, with the decoder, the luminance quantization parameter value and the first image-region-dependent chroma quantization parameter bias value to determine a first chroma quantization parameter value by adding the first image-region-dependent chroma quantization parameter bias value to the luminance quantization parameter value; and \n decompressing an image region of the video image using the luminance quantization parameter value and the first chroma quantization parameter value, \n wherein the first chroma quantization parameter value is less than or equal to a predetermined maximum value, \n wherein the first chroma quantization parameter value is no less than one, and \n wherein the first chroma quantization parameter value is determined for the first chroma channel (V).
