Color Correction
The color correctors can operate as Processing
Amplifiers (Proc Amps) in the HSL (Y-Cr-Cb)
color space or as RGB Color Correctors in the
RGB color space. Proc Amps and RGB Color
Correctors apply color correction to video on
input to the switcher, before the crosspoint, and
on the output from the switcher. Correction
applied to the input video is then available to
all MEs. Output based correction is only
available on output BNCs 5 to 14.
The total number of color correctors can be
increased to 34 (7 in UHDTV1) with the
activation of the Extra SD or HD I/O Processor
option.
Color correction is additive, allowing you to
apply any combination of Proc Amp and RGB
Color Corrector based adjustment to a video
signal. If multiple color corrections are applied,
the correction is applied first, and the bus-based
correction is applied after that.
To Assign a Color Corrector to a
Source (UHDTV1 Only)
You must assign a color corrector to an input or
output to correct the color of the video.

Proc Amp Color Correction
The Proc Amp video correction allows you to
adjust the gain, offset, black level, and gamma
of the video signal.
To Apply a Proc Amp to a Video Source
A Processing Amplifier (Proc Amp) applies color
correction in the HSL (Y-Cr-Cb) color space for
switcher sources.
Note:
Only outputs 5 to 14 support output color correction.

Luma Gain
Adjust the Hue. Increasing the Hue
Rotation turns the color wheel
clockwise, and decreasing the Hue
Rotation turns the color wheel
counter-clockwise.
