Description
The higher the value, the more greenish the picture
becomes. The lower the value, the more reddish the
picture becomes.
Refers to the amount of that color in a video picture.
Lower settings produce less saturated colors; in fact,
a setting of "0" removes that color from the image
entirely. If the saturation is too high, that color will be
overpowering and unrealistic.
A high value results in a sharper picture; a low value
softens the picture.
Reflects the relationship between input source and
picture brightness.
