HCFR has the math for it. The problem is that it doesn't show me the Y target itself but the error only and my sensor isn't supported, so I can't do the adjustment in real-time with HCFR. I think you can get a copy from the source code and copy the ralated math... I guess it's something like: - The WP is = xyY - The primaries are = xy, xy, xy - How much R,G,B intensity (Y) do I need to mix this WP? WP should be D65 and actual Y, xy for R,G,B should be Rec709 2011/9/6, Graeme Gill <graeme@xxxxxxxxxxxxx>: > János, Tóth F. wrote: >> Well, HDTVs usually offer 6x3 adjustable contols for gamut calibration: >> primaries and secundaries with either Red,Green,Blue or >> Huye,Saturation,Luminance values for each of the six directly adjustable >> colors. > > Hi, > without some concrete (ie. maths + standards) information, it's > not really possible to know what you are after.
