Cautions on 3D irregular color correction adjustment
The following measurement and adjustment must be carried out:
• In a dark room (take care for stray light)
• Using diffuse reflection type (mat type) screen in the uniform conditions.
Settings of the projector must be carried out in the following conditions:
• Do not save power (to keep the lamp to the stable condition during measurement)
• Automatic search cancel (to fix INPUT1)
• INPUT1 RGB mode (cancel the component mode of INPUT 1, just in case)
(1) System setting ("setting" - "system setting")
System optional
Simultaneous write in of 3D correction value:
Char transmission interval:
Binary interval:
Adjustment Conditions
1. Feed the DTV monoscope pattern
signal.
2. Select the following group and sub-
jects.
Group: COMPO
Subjects: C-R1-BLK, C-B1-BLK
1. Apply the automatic color correc-
tion using the automatic color irregu-
larity correction system (ccdc).
1. Input the RGB 10-step gray-scale
(inverse vertically) signal.
2. Select the following group and sub-
ject.
Group: LINE
Subject: OPT-MECH
1. Feed the RGB 50% gray pattern
signal.
2. Select the following group and sub-
jects.
Group: OUTPUT1
Subjects: S-R1-BLK, S-R1-GAIN, S-
G1-BLK, S-G1-GAIN, S-B1-BLK, S-
B1-GAIN
3. Have the BM-5 brightness meter and
the standard white board at hand.
Adjustment Procedures
1. Using the set's control switch or the
remote controller button, adjust the
settings to have the same white bal-
ance as on the standard monitor.
1. Make sure that no remarkable uneven
color remains on the screen.
Check the tracking of the gradation on
the lower side.
In case that it is bad, adjust the OPT-
MECH value to the optimum.
(It takes 2 - 3 seconds for changing for
selection.)
0:Red and blue up
1:Red and blue down
2:Initial value (Normal)
1. Make the S-R1-GAIN setting the
same as the R1-GAIN one.
Make the S-G1-GAIN setting the
same as the R1-GAIN one.
Make the S-B1-GAIN setting the
same as the R1-GAIN one.
Make the S-R1-BLK setting the same
as the R1-BLK one.
2. Adjust the S-B1-BLK and S-G1-BLK
settings so that the chromaticity on
the brightness meter should be as
follows.
x: .313±7/1000
y: .350±10/1000
