WHITE BALANCE ADJUSTMENT: Adjust the white 144 gradation using
RGB CUTOFF2 and then the white 73 gradation with RGB-GAIN.
TEST SIGNAL ADJUSTMENT
- [Input signal] : Display the WB test signals with built-in DVP of white 56% (144 gradations) and 29% (73 gradations) on the left and right of the screen respectively by using the remote control code “011110010001010”.
[Adjustment value]:
- White 56% x = 0.261 ±0.004 ±0.01 Radius from the center point x = 0.277 ±0.004 ±0.01 Radius from the center point.
- White 29% x = 0.261 ±0.002 ±0.01 Radius from the center point x = 0.277 ±0.002 ±0.01 Radius from the center point.
[Adjustment method by bus]:
- Cutoff: RGB CUTOFF2 G CUTOFF2 = Fixed to 0. Vary RB CUTOFF2: Adjustment range: ±30.
- Gain: RGB-GAIN G-GAIN = Fixed to 0. Vary RB-GAIN. Adjustment range: ±30.
(The adjustment value is measured
with MINOLTA CA-210 and the correction mode is measured in the mode compatible
with CH02 “TOPCON”.)
- Perform the factory setting using the remote control for adjustment. (This setting must be done after performing the MCL data setting.)
- “H” standing for factory setting 1, “M” standing for factory setting 2 or “X” standing for factory setting 3 is displayed in the upper left portion of the screen by continuing to press the Factory Setting key on the remote control for adjustment.
