point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
4) Set the 4th point to the specified gradation level. Correct the G setting (656 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.
5) Set the 3rd point to the specified gradation level. Correct the G setting (528 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

7) Set the 1st point to the specified gradation level. Correct the G setting (184 x 6th-
point G setting / 928) (rounded off), and make the R and B settings to their reference
levels.

* Initial R, G and B settings at point 6: Gradation level set at 928
* Initial R, G and B settings at points 1 thru 5: Corrected G setting at each point
(This is because the adjustment is made to achieve the same remainder of RGB setting /
4 at each point.)
