Color Corrector Functions
Chapter 9 Color Corrector
There are three modes for luminance processing, as
follows.
Tint mode: adding a specified color to the original video
signal.
Color Modify mode: adjusting the original video signal.
Y Modify mode: adjusting the output levels of the input
luminance signal.
• White balance adjustment: setting the output level
for an input luminance signal at the 100% level.
• Black balance adjustment: setting the output level
for an input luminance signal at the 0% level.
• Y lift correction: adjusting the curvature of the
curve.
• Y dark correction: adjusting the position of the
maximum point of the curve.
It is also possible to mask part of the region to be corrected.
Applying luminance processing
1
In the CCR menu, press VF1 ‘CCR1’ and HF5
‘Luminance Process.’
The Luminance Process menu appears.
2
In the <Luminance Process> group, press [Luminance
Process], turning it on.
3
In the <Mode> group, specify the adjustment mode.
Tint: add a specified color to the original video signal.
Color Modify: adjust the original video signal.
Y Modify: adjust the output levels of the input
luminance signal.
When tint mode or color modify mode is selected, skip
to step 4.
When Y modify mode is selected, adjust the following
parameters.
4
In the <Bound> group, make the settings for the three
regions (Dark, Middle, and Bright).
[Level] parameters: set the boundaries of the three
regions.
[Soft] parameters: set the degree of boundary
softness of the three regions.
