tint control การใช้

NTSC receivers have a tint control to perform colour correction manually.
The tint control is normally set by sight to create satisfactory skin tones in a picture.
The PAL standard automatically cancels hue errors by phase reversal, so a tint control is unnecessary yet Saturation control can be more useful.
Any phase errors could then be compensated for by using a tint control knob on the front of the set, normally unneeded on a PAL set.
Television sets produced in recent decades typically include a ( sometimes non-defeatable ) distortion of the color decoding spectrum, to minimize the visual effects of phase error and lessen the need to adjust the tint control.
