GAIN UP formula = GAIN adjustment value (hex)(*3) x {1+ (Data (hex) of SBCN1 or SBCN2)/FF (hex) }
(*3): GAIN adjustment value is the following data (in OSM FACT3).
9300K R-GN1 G-GN1 B-GN1
6500K R-GN2 G-GN2 B-GN2
5000K R-GN3 G-GN3 B-GN3
(*4): When the SUPER BRIGHT MODE-1 or MODE-2 is ON, the GAIN cannot be adjusted as shown in the
table in Sec. 1.3.6.1 "Adjustment item/operating function in selecting SB Mode". However, when the
SUPER BRIGHT MODE is OFF, the MAX GAIN value calculated with the following formula will be written in
the following EEP address so that the GAIN value cannot be increased above that of the SUPER BRIGHT
MODE-1 and MODE-2 ON status.
MAX GAIN = Maximum value (hex) for R/G/B GAIN adjustment (*5) x {1 + (SBCN1 or SBCN2 data
(hex))/FF (hex)}
