10. White balance adjustment
For white balance adjustment, adjust the offset values on pages 12/17.
[Condition of the unit for inspection]: PC mode, Modulated light (+16), Color temperature (High)
[Input signal condition]: HDMI 1080i 15IRE(LO), 78IRE(HI)
[Adjustment reference device]: Minolta CA-210
[Adjustment procedure]
1) Display the current adjustment status at R/G/B_GAIN(HI). (Page 12/17 of process adjustment)
The signal of 78IRE is input.
2) Read the value of the luminance meter. x=0.272, y =0.277
3) Change R_GAIN(HI)/ B_GAIN(HI) (Adjustment offset value) on page 12/17 of process adjustment so that the values of the luminance meter
approach x=0.272 and y =0.277.
(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R or B must be fixed.)
4) Display the adjustment status of the current R/G/B_GAIN(LO).
The signal of 15IRE is input.
Change R_GAIN(LO)/ B_GAIN(LO) (adjustment offset value) on page 12/17 of process adjustment so that the values of the luminance meter
approach x =0.272 and y = 0.277.
approach x =0.272 and y = 0.277.
5) Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.
[Adjustment reference standard value]
Adjustment spec
± 0.002 Inspection spec ± 0.004 (point LO)
Adjustment spec
± 0.001 Inspection spec ± 0.002 (point HI)
6) After completing adjustments, set EEP SAVE (17/17) to ON in the process menu to save the white balance adjustment value.
