(19) Set the G of point Max. to the default value
(4080 x G value of point 2 / R2). Set the R,B
Max. value [G – G value of point 2 + (R,B
max
value of point 2)
(20) Calculate the slope R2 G2
slope, slope,
between MAX and Point2.
R2 (R - R )/(4080-3264)
slope = max high
(21) Calculate the correction value
R G B
high, high, high.
R R2 (3561-3264)
high = slope X
Set the reference value R,G,B of point 2
(22)
(R2 )=R2+ R
high
Calculate the slope R1 G1
(23)
slope,
between Point2 and Point1.
R1 (R - R )/(3264-816)
slope = high low
Calculate the correction value R
