Color Correction
Note: This feature is available on the Carbonite Black+ and
Carbonite Black+ 12G only.
Color correction in the switcher is performed by either
Processing Amplifiers (Proc Amps) in the HSL (Y-
Cr-Cb) color space or by RGB Color Correctors in the
RGB color space. Both Proc Amps and RGB Color
Correctors allow you to 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 outputs 3, 4, and 5.
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.
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
1. Double-press the source button for the input video
source you want to apply the Proc Amp to.
If a device is assigned to the video source, you
may have to press NEXT to view the correct page.
Tip: If correction has already been applied ( ON ), press
Reset to return the Proc Amp and Color Correction to the
default values.
2. Use the PrcAmp knob to select ON .

a) Use the Cntrl knob to select GamVal .
b)
Use the
Value
knob to adjust the luminance
gamma value.
10. Adjust the gamma offset as follows:
a) Use the Cntrl knob to select GamOff .
b) Use the Value knob to adjust the luminance
gamma offset.
11. Adjust the Cr (red color difference) gain as
follows:
a)
Use the
Cntrl
knob to select
CrGain
.
b)
Use the
Value
knob to adjust the gain of the
Cr.
12. Adjust the Cr (red color difference) offset as
follows:
a) Use the Cntrl knob to select CrOff .
b) Use the Value knob to adjust the offset of the
Cr.
13. Adjust the Cb (blue color difference) gain as
follows:
a)
Use the Cntrl knob to select CbGain .
b)
Use the Value knob to adjust the gain of the
Cb.
14. Adjust the Cb (blue color difference) offset as
