What we actually want to predict, though, is how those surfaces would have looked if they had been lit by the same illuminant as your monitor, in order to make all colors in the scene match the change of illuminant. 🔗White Balance in the Chromatic Adaptation Transformation (CAT) tabĬhromatic adaptation aims to predict how all surfaces in the scene would look if they had been lit by another illuminant. To improve the color accuracy of the input color profile using a color checker chart. To produce a grayscale output based on the relative strengths of the R, G and B channels, in a way similar to the response of black and white film to a light spectrum. To adjust the color saturation and brightness of the image, based on the relative strength of the R, G and B channels of each pixel. Here, the white balance module makes some initial adjustments (required for the demosaic module to work effectively), and the color calibration module then calculates a more perceptually-accurate white balance after the input color profile has been applied.Īs a simple RGB channel mixer, adjusting the R, G and B output channels based on the R, G and B input channels, to perform cross-talk color-grading. To adjust the white balance ( chromatic adaptation), working in tandem with the white balance module. This simple yet powerful module can be used in the following ways:
