Color Matching - Sanyo PDG-DHT8000L Owner's Manual

5
Set 'Test pattern' to 'On' to display a 50 % white image. The overlap area will be brighter than the non-overlapping
area. Adjust the Black level in the Edge blending dialog box to increase the brightness of the non-overlapping area so
that the unevenness is reduced.
✔ Note:
• The overlapping area might become uneven depending on the images. In such a case, it is recommended to
decrease the contrast of the images in the Image Adjust Menu or set the BrilliantColor function to 'Off'.
If the colors of the left and right images do not match, then follow the next step.

Color matching

6
Select 'Color matching' in the setting menu and display the Color matching dialog box.
Then, set 'Color matching' to 'On' and adjust the color settings (Red/Green/Blue/White).
(Refer to page 53 for operation procedure.)
7
Select 'Advanced color matching' if you need further adjustment.
In the Advanced color matching dialog box, set 'Advanced color matching' to 'On' and adjust the values of Target (Red/
Green/ Blue/ Cyan/ Magenta/ Yellow/ White).
✔ Note:
• When you change the values of Target, make sure that each
Target value should be within the range of Measured value.
(e.g., In the case of the Fig.1, the X value of Target-Red
should be within 0.623 which is the X value of Measured-
Red.)
8
If the colors of the left and right images do not match, even
if the Target values are adjusted, use a colorimeter which
is capable of measuring the chromaticity coordinates and
luminance. Follow the steps below.
1. Set 'Auto test pattern' to 'On' in the Advanced color
matching dialog box.
2. Put the cursor in the Mesured-White and press the
SELECT button to display a white pattern.
3. Measure the chromaticity coordinates (x,y) and
luminance (lx) by using the colorimeter.
4. Enter the obtained (x,y) values in the Mesured-White.
(The (L) value of Mesured-White should be left at 1.000.)
5. Put the cursor in the Mesured-Red and press the SELECT
button to display a red pattern.
6. Measure the chromaticity coordinates (x,y) and
luminance (Lx) by using the colorimeter.
7 . Enter the obtained (x,y) values in the Mesured-Red. Then,
calculate the (L) value of Mesured-Red by applying the
following formula and enter the value.
(L) value of Mesured-Red = [Lx of Red] ÷ [Lx of White]
8. Enter the values of Mesured-Green, Mesured-Blue, and
Mesured-Half white in the same way as Mesured-Red.
9. Adjust the values of Target again.
10. Select 'Store' to complete. (Apply the same adjustment
to the other projector if necessary.)
Set to 'On'.
