COLOR SPACE CONVERSION MATRIX
The ADV7611 provides any-to-any color space support. It supports formats such as RGB, YUV, YCbCr and many other color spaces.
The ADV7611 features a 3×3 CSC in the CP block (CP CSC), as shown in Figure 26. The CP CSC also provides color controls for
brightness, contrast, saturation and hue adjustments. The DPP block features an automatic CSC. The ADV7611 automatically configures
the DPP CSC depending on the input and output formats and the use of the color control feature.
