1.5.2.Color balance adjustment

You can adjust luminance and tint between each screen of a display wall. In principle, they should be adjusted according to (3) CSC adjustment. However, follow (2) BLACK LEVEL, (4) WHITE BALANCE and (5) GRADATION adjustments, if necessary.

After that, set TARGET COLOR and SENSOR to maintain the uniformity over the long term.

1.5.2.2. BLACK LEVEL

This adjustment is not necessary.

Adjust it when the difference of luminance and tint in black is noticeable between each screen. Be careful not to deteriorate the contrast because it can be adjusted only by increasing the black luminance level.

[Procedure]

1.Press [TEST] button three times and press [R], [G] and [B] button to display the black signal in the adjustment white.

2.Select BLACK LEVEL in INSTALLATION in the system menu.

3.Select R-, G- or B-LEVEL and adjust each color level in black.

1.5.2.3.CSC (Color Space Control) There are 3 ways to adjust CSC values.

• By “Auto CSC” function in Wallaby

• With a color analyzer

• By manual

1.5.2.3.1.By “Auto CSC” function

Using “Auto CSC” function in adjustment software, “Wallaby”, the color balance can be automatically adjusted among a display wall. See “Auto CSC function” on page 103 for detail.

1.5.2.3.2.With color analyzer

Optimum CSC values can be automatically calculated from the color component data in each screen measured with a specified color analyzer. See separately provided “CSC Auto-adjust Software Operation Manual” for detail.
