color, and adjust the RGB so that it becomes the standard value through the negative
adjustment.
3) Set the point 1 to the specified gradation, and set the G correction value (560 x G
value of point 2/2880) then adjust RB so that it becomes the standard value.
4) Calculate the RGB value of the maximum.
G(MAX) = 4080 x G(High) / 2880
R(MAX) = G(MAX) + R(High) - G(High)
B(MAX) = G(MAX) + B(High) - G(High)
(If G(MAX), R(MAX), B(MAX) > 4080, set as G(MAX), R(MAX), B(MAX) = 4080)
5) Enter the maximum value of the RGB values.
