8.4.3. Saturation
Some ME2P-GC-P series cameras support saturation function. Saturation function can changes the
colorfulness (intensity) of the colors to achieve the goal image effect.
1) Prerequisites
If the SaturationEnable parameter is available, it must be set to On .
2) Configuring saturation
Enter the expected value for the Saturation parameter and the range is 0 to 128. By default, the parameter
is set to 64 (no saturation perform)
3) How it works
The saturation adjustment is performed by a 3 × 3 matrix. When the saturation intensity is modified, the
saturation can be changed by modifying the adjustment matrix A.

Saturation adjustment and color correction adjustment both adopt the form of a matrix, so the saturation
is adjusted at the same time after color correction is enabled.
