Secondary Color Correction
Operations
For the six colors R (red), G (green), B (blue), Y (yellow),
C (cyan), and M (magenta), adjust the luminance and
saturation, and also the hue within a range of ±30 degrees
of the center value for each color.
You can mask a part of the region to be corrected.
Applying secondary color correction
1 In the CCR menu, press VF1 ‘CCR1’ and HF3
‘Secondary CCR.’
The Secondary CCR menu appears.
2 In the <Secondary CCR> group, press [Secondary
CCR], turning it on.
3 In the <Secondary CCR Adjust> group, select the
color for which you want to make the setting.
4 Adjust the following parameters.
Dark Middle Bright
Input signal luminance level
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.

Masking a part of the secondary color
correction
Set [Mask] to On in the Secondary CCR menu, then carry
out the same operation as described under “Masking a part
of the primary color correction” (page 243).

Luminance Processing Operations
After converting a signal to which RGB color correction
has been applied to a YUV signal, divide the luminance
levels into three regions, referred to as Dark, Middle, and
Bright, and apply video signal adjustments to these
regions.

It is also possible to mask part of the region to be corrected.
