The Video Proc Amp tab has the following controls.
Brightness and
Contrast These are terms for what one would call a contrast ratio. It’s a measure of a
display system, defined as the ratio of the brightest color (white) to that of the
darkest color (black) that the system is capable of producing. A high contrast
ratio is a desired aspect of any display, but with the various methods of
measurement for a system or its part, different measured values can
sometimes produce similar results. The control exists in the event you need to
change the ratio of an incoming signal.
Hue Hue adjustment only functions for NTSC video.
Saturation In color theory, saturation or purity refers to the intensity of a specific hue. A
highly saturated hue has a vivid, intense color, while a less saturated hue
appears more muted and grey. With no saturation at all, the hue becomes a
shade of grey. You are able to adjust the saturation level in the event it is
altered by a video feed.
Sharpness This slider has six positions corresponding to six hardware filter settings.
Generally, the positions to the left result in smoother video, the positions to
the right result in sharper video. Since each step engages a different
combination of discrete filters, some steps may result in slight differences
while other steps may result in large differences.
Gamma You would rarely use this control; however, a need may arise for its use. In the
simplest terms the input of a feed from a device into your card may not match
the digital output on your screen. The gamma control allows you to balance
the red, blue and green from the input to output within the normal range of
people’s perceptions.
