Setting of the color saturation
void Set_Saturation(WORD nDevNo,WORD nSat_U,
WORD nSat_V);
nSat_U: Saturation of the U-color portion (0..511, Default = 254)
nSat_V: Saturation of the V-color portion (0..511, Default = 180)
This function allows the separate setting of the color saturation for the
U- and V-color portion. With this parameters the amplification can be
separately regulated for both color portions.
Usually the relation of the values nSat_U and nSat_V are equal. The
control of the difference between the U- and V- portion allows the
elimination of color cast (which might stem from unbalanced color
cameras). The resulting effect will be a change of the color of the
image.
nSat_U = U-saturation [%]
.
2.5400 [1/%] ; 0% ... 201.18 %
nSat_V = V-saturation [%]
.
2.1396 [1/%] ; 0% ... 238.83 %

Reading the content of the registers for color saturation
WORD Get_Sat_U(WORD nDevNo);
WORD Get_Sat_V(WORD nDevNo);
return value: value of the actual U- or V-color saturation
This function provides the content of the registers for the color
saturation.
