Claim 12:
13. A device comprising:
a processor configured to:
obtain from a bitstream information representative of a pair of scaled chroma components and metadata used to convey an information data representative of a chroma correction function and at least one correction factor;
obtain at least one corrected chroma correction function by multiplying the chroma correction function by the at least one correction factor;
obtain refined scaled chroma components by multiplying scaled chroma components of an image by said at least one corrected chroma correction function; and
reconstruct a corrected image by deriving components of the reconstructed corrected image as a function of said refined scaled chroma components and a corrected matrix resulting from the division of coefficients of an inverse of a theoretical color space matrix conversion by the at least one correction factor.
