4. Adjust the y value in the W/B HIGH G Gain. When X
value inclusive of y value is bigger than the specific
value, regard Blue as the referenced color.
To the contrary, when smaller, regard Red as the
referenced. Color temperature is to be adjusted to
satisfy with the follows in the GAIN other than such
referenced colors.
5. Input the 15KHz Component Flat Field 30 IRE signal
to the INPUT-A.

3-8-3. 3Dγ Overview
Refer to the principle mentioning next of 3Dγ before
advancing 3Dγ adjustments.
3Dγ consists of total 504 points which is figured out
multiplying brightness 8 points in the level, 9 points in the
horizon and 7 points in the vertical direction.
It has functions to enable individual adjust W/B in the light
of R, G, and B.
Accordingly, 504 x 3(RGB) = 1512 items is required in
order to complete full adjustments.
For convenience, however, this is replaceable provisionally
by the following methods.
The following layer tree is the [GAMMA] Menu.
To adjust each LEVEL, the internal signal (Flat Field) of a
LEVEL will be automatically shown.
