Correction of the hue (NTSC only)
void Set_Hue(WORD nDevNo, short nHue);
nHue: hue, phase position of the color signal (-128..127)
With this function you can control the hue for the digitization of
NTSC- color images, which is accomplished by changing the phase
position of the color signal. For PAL this value is insignificant since
phase errors are automatically compensated.
One LSB corresponds to a correction of the phase angle of 0.7°,
therefor the color signal can be varied in the range of -89.3° to +90°
This value must be set to 0 to ensure proper functioning of the color
decoder under PAL.
Reading the content of the register for hue
short Get_Hue(WORD nDevNo);
return value: value of the phase position of the color signal
This function provides the hue value.
