Color Corrector
Functions
This section describes the color corrector functions.
For each of the following operations, it is possible to copy
or swap data between two color correctors (CCR1 and
CCR2).
Input Video Processing Operations
Carry out the following corrections to a YUV signal before
conversion to an RGB signal.
• Overall gain adjustment of the video signal
• Gain adjustment of the Y signal
• Gain adjustment of the C signal
•Hue delay
• Black level adjustment
To apply input video processing effects, use the following
procedure.
1
In the CCR menu, press VF1 ‘CCR1’ and HF1 ‘Input
Process.’
The Input Process menu appears.
2
In the <Input Process> group, press [Input Process],
turning it on.
3
Adjust the following parameters.
To return the parameters to their default settings
Press [Unity] in the <Input Process> group.
Primary Color Correction
Operations
Carry out the following corrections to each of the R, G, and
B signals.
Black balance adjustment: setting the output level for a
0% level input signal.
White balance adjustment: setting the output level for a
100% level input signal.
Gamma correction: adjusting the curvature of the gamma
curve.
Knee correction: adjusting the position of the maximum
point of the gamma curve.
It is also possible to mask part of the region to be corrected.
Applying primary color correction
1
In the CCR menu, press VF1 ‘CCR1’ and HF2
‘Primary CCR.’
The Primary CCR menu appears.
2
In the <Primary CCR> group, press [Primary CCR],
turning it on.
3
In the <Primary CCR Adjust> group, select the setting
item.
Black: black balance adjustment
White: white balance adjustment
Gamma: gamma correction
Knee: knee correction
