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.
Click

.
2.
Click the
ProcAmps and Color Correctors
button and select the input or output that you want
to apply the Proc Amp to.
Tip:
If correction has already been applied (
ON
), press
Reset
to return the Proc Amp and Color Correction to the
default values.
3.
Click an
Enable
button to turn the Proc Amp on
(

) for the selected input or output.
4.
Use the sliders to adjust the video source.
•
Gain
— adjust the chrominance and
luminance gain together.
•
Chroma Gain
— adjust the chrominance
gain only.
•
Luma Gain
— adjust the luminance gain
only.
•
Hue Rotation
— adjust the Hue. Increasing
the Hue Rotation turns the color wheel
clockwise, and decreasing the Hue Rotation
turns the color wheel counter-clockwise.
•
Black Level
— adjust the black level. Black
level acts as a luminance offset.
•
Gamma
— adjust the luminance gamma
value.
•
Gamma Offset
— adjust the luminance
gamma offset.
•
Cr Gain
— adjust the gain of the Cr (red color
difference).
•
Cr Offset
— adjust the offset of the Cr.
•
Cb Gain
— adjust the gain of the Cb (blue
color difference).
•
Cb Offset
— adjust the offset of the Cb.
RGB Color Correction
Note:
This feature applies to the Ca and Carbonite
MultiMedia only.
The RGB color correctors allow you to adjust the red,
green, and blue component gain, offset, and gamma of
the video signal.
