4 - 6 Color uniformity adjustment
Preparations
1. Perform these adjustments after the white balance
adjustment described in Section 4-5.
2. Make a color uniformity adjustment for the following
three tones.
·
MIN tone (approx. 10% input signal)
·
MID tone (approx. 50% input signal)
·
MAX tone (approx. 75% input signal)
(Note that the MIN tone need not be adjusted when
there is no conspicuous color shading during a
black signal input.)
3. Place the cursor on the tone to be adjusted in the
Adjust menu and press the [
] key. This displays
the Adjust Tone menu at the bottom of the screen.
Select the major adjustment lattice point No. and
color, then adjust them.
4. The major adjustment lattice point numbers (a total
of 17 points) corresponds to the major adjustment
lattice point positions in the diagram on the right.
The color uniformity of the entire screen can be
adjusted by adjusting the white balance for each of
the points starting in order from the low numbers.
5. Adjustment point No. 1 should not be adjusted,
because it controls the brightness of the entire
screen.
6. To temporarily turn correction off, place the cursor
on ON in the Adjust Tone menu and press the [
]
key. To turn it on again, place the cursor on OFF in
the Adjust Tone menu and press the [
] key.
7. Although this adjustment can also be made using
internal signals, we will here use the [MENU
SELECT] key on the Remote control transmitter to
select the following two signals.
·
Solid monochrome adjustment color (use G
color adjustment when a color differential meter
is used)
·
Solid white (use for adjustment other than
above)
8. Reset color shading correction before adjustment.
·
When 3 tones and all colors are to be reset,
place the cursor on [C. UNIF]. in the Adjust
menu, press the [RESET] key and select
[DEFAULT].
·
When only 1 tone is to be reset, place the cursor
on the tone to be reset press the [RESET] key
and select [DEFAULT].
·
Single tone and monochrome resets cannot be
performed.
