2-4. White Balance Adjustment on
Servicing
2-4-1. White Balance Adjustment
Input the 10 STEP signal to INPUT-A, and observe the
chromaticity of each luminance.
When varying the chromaticity of each luminance, perform
the following adjustments.
1) MID Mode of INPUT-A
1.
Input the 80 IRE FLAT FIELD signal to INPUT-A.
2.
Adjust the chromaticity (x at 0.290, y at 0.320) values
by the GAIN R and B of W/B MID mode.
3.
Set the INPUT signal to the 30 IRE FLAT FIELD
signal.
4.
Adjust the chromaticity (x, y) to (0.290, 0.320) by the
BIAS R and B.
5.
Repeat above steps 1 to 4 until the chromaticity
become the following values.
(0.290
±
0.002, 0.320
±
0.004)
2) HIGH Mode of INPUT-A
1.
Input the 80 IRE FLAT FIELD signal to INPUT-A.
2.
Set the GAIN G to the integar of MID mode value
x
0.96 with the HIGH mode of the W/B.
3.
Input the 30 IRE signal to INPUT-A.
4.
Adjust the chromaticity (x at 0.284, y at 0.298) values
by the BIAS R and B of W/B HIGH mode.
5.
Input the 80 IRE signal to INPUT-A.
6.
Adjust the chromaticity (x at 0.284, y at 0.298) values
by the GAIN R and B.
7.
Repeat above steps 3. to 6. until the chromaticity
become the following values.
x: 0.284
±
0.002, y: 0.298
±
0.004
3) LOW Mode of INPUT-A
1.
Input the 80 IRE FLAT FIELD signal to INPUT-A.
2.
Input the 30 IRE signal to INPUT-A.
3.
Adjust the chromaticity (x at 0.313, y at 0.329) values
by the BIAS R and B of W/B LOW mode.
4.
Input the 80 IRE signal to INPUT-A.
5.
Adjust the chromaticity (x at 0.313, y at 0.329) values
by the GAIN G and B.
6.
Repeat above steps 2 to 5 until the chromaticity
become the following values.
x: 0.313
±
0.002, y: 0.329
±
0.004
