3-4-3. Video W/B Adjustment
3-4-3-1. High Mode
1. Input the 15k Component signal to INPUT-A.
2. The HIGH MODE will be set.
3. Perform the following processes on the 3-3-2 adjustment
value, and copy the value to the HIGH MODE.
R GAIN:Adjustment value in LOW Mode –10
G GAIN:Adjustment value in LOW Mode –10
B GAIN:Adjustment value in LOW Mode –10
R BIAS:Adjustment value in LOW Mode +1
G BIAS:Adjustment value in LOW Mode +1
B BIAS:Adjustment value in LOW Mode +1
4. Input the 15k Component Flat Field 80 IRE to INPUT-
A.
5. Lower G GAIN, and adjust the Y value to this value.
6. Take Blue as the reference if the X value is greater than
the specification, and RED as the reference when smaller.
7. Adjust to the following chromaticity at GAINs other than
the reference color.
8. Memorize the adjustment value.
9. Input the 15k Component Flat Field 30 IRE to INPUT-
A.
10. Adjust to the following chromaticity at BIASs other than
the reference color.
11. Perform tracking adjustment so that 80IRE and 30 IRE
satisfy the specification.
12. Memorize the adjustment value.
HIGH MODE chromaticity specification:
(x,y)=(0.275, 0.312) ± 0.005 (80IRE)
(x,y)=(0.275, 0.312) ± 0.007 (30IRE)
