Abstract:
The value of a quantization parameter for at least one second color component of an image or image portion is determined using a current color format among several possible color formats. The determination comprises the steps of selecting at least one function associated with a possible color format, and determining the value of the quantization parameter for the second color component by applying said at least one function to a value of an intermediate quantization parameter which is based on the value of the quantization parameter of the first color component of the image or image portion. The at least one function is selected independently from the current color format.

Claim (Index 13):
A device for decoding an image or an image portion comprising:\n a determining unit configured to determine data indicative of a color format, and determine a value of QPC which is a quantization parameter for at least one chroma component of an image or an image portion to be decoded using the following function to obtain the value of QPC from a value of QPI which is an intermediate quantization parameter when the data does not indicate 4:2:0 color format,\n QPC =MIN( QPI, 51), \n the value of QPI being based on a value of a quantization parameter for a luma component of the image or the image portion, and using a different function from the above function to obtain the value of QPC from the value of QPI when the data indicate 4:2:0 color format; and a decoding unit configured to use the determined value of QPC to decode the image or the image portion.
