Systems and methods for selecting a white point for image displays
First Claim
Patent Images
1. For a display device, a method for changing the chromaticity triangle calculations of input image data, the method comprising:
- converting input image data to a first color space, said first color space having the same white point as a white point of the display device; and
calculating the chromaticity triangle of the converted input image data,wherein the input image data are converted into values that have the same white point as the display device, and the converted values have their chromaticity triangles calculated.
