10. White Balance Adjustment
For white balance adjustment, adjust the offset values on pages 12/16.
1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 12/16 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 12/16 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 12/16 of process adjustment so that the values of the luminance meter
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.
