Abstract:
Color correction in high dynamic range video (HDR) using 2D look-up table (LUT) may be provided. The color correction may be applied in a decoder after decoding the HDR video signal. For example, the color correction may be applied before, during, or after chroma upsampling of the HDR video signal. The 2D LUT may include a representation of the color space of the HDR video signal. The color correction may include applying triangle interpolation to the sample values of the color component of the color space. The 2D LUT may be estimated by an encoder and signaled to the decoder. The encoder may decide to reuse a prior-signaled 2D LUT or use a new 2D LUT.

Claim (Index 9):
The method of  claim 1 , further comprising receiving a second chroma sample, wherein the input luma value is set to the first luma sample, and wherein the input chroma value is determined by interpolating at least the first chroma sample and the second chroma sample.
