The color enhancement options.
The level of skin tone protection. The value range is [0.0,1.0].
0.0 means no skin tone protection. The higher the value, the higher the level of skin tone protection. The default value is
1.0. When the level of color enhancement is higher, the portrait skin tone can be significantly distorted, so you need to set the level of skin tone protection; when the level of skin tone protection is higher, the color enhancement effect can be slightly reduced. Therefore, to get the best color enhancement effect, Agora recommends that you adjust
skinProtectLevel to get the most appropriate values.
