ADJUSTMENTS
9 Adjustment Using Moving Images
The adjustment using images adjusts the overall joining of the screens by loading discs used by users (for actual perfor-
mance) and discs always used for adjustments. View the overall screen and adjust the screen with the greatest difference to
the other screens. The specific method is;at first, focus on the brightness, make the brightness the same, and correct the
differences in R, G, and B. Pay the attention that changing the HI LIGHT value affects the balance of the LOW LIGHT consid-
erably. Strictly speaking, as W/B deviation cannot be checked using moving images and W/B cannot be corrected just by
performing fine adjustments, check using rough adjustments.
If the DEMONSTRATION-II LD can be used, correct the following points.
[1] Dark images (Almost black image:FRAME No. 32300 to 33200)
Check that the brightness of the screens appears the same.
Check that black is not blur or emphasized.
[2] Bright images (Almost white image:FRAME NO. 7400 to 8100)
Focus on where the brightness is the same, especially the white peak, and check in the same way as for dark
images in (1).
[3] Skin color images (FRAME NO. 26900)
Check if the skin color of a face image is the same as in the other screens.
[4] Colored images (FRAME NO.19100)
Use when performing adjustments during VIDEO input or Y/C input. Adjust so that the colors of vegetables,
fruits, etc. are of the same brightness and same depth.
If consistency cannot be adjusted with animated images, re-input the rough adjustment data and re-adjust.
* View the moving images. If a screen is darker than the others due to excessive ABL, increase the contrast and
decrease the R, G, B High Light so that ABL is suppressed.
[5] White peak images (FRAME NO.08272)
Readjust the Linear White adjustment, if the whiteness on the white peak screen differed on each screen.
0 Confirm the moving images
View the moving images. If W/B is incorrect, set to rough adjustment. If the luminance of the multi-screen is
dark or inconsistent, set the ABL switch.
- Precautions
1 Avoid adjusting with images with high tube radiation (FRAME NO. 13590)
If only one spot is bright in a very dark image, the screen will look bright due to the spot.
2 Precautions on screen hue
If the hue of the screens is green or yellow, images will not be displayed clearly. The white parts of bright
images especially will appear yellow. These images can be made clear by adjusting so that they appear
slightly bluish.
However, if made bluish excessively, brightness may appear insufficient due to the CRT characteristics.
