5.2.3. LED White balance table
5.2.3.1. Cool Mode
1) Purpose : Especially G-gain fix adjust leads to the
luminance enhancement. Adjust the color
temperature to reduce the deviation of the
module color temperature.
2) Principle : To adjust the white balance without the
saturation, Adjust the G gain more than 172 ( If R
gain or G gain is more than 255 , G gain can
adjust less than 172 ) and change the others (R/B
Gain).
3) Adjustment mode : mode – Cool
5.2.3.2. Medium / Warm Mode
1) Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
2) Principle : To adjust the white balance without the
saturation, Fix the one of R/G/B gain to 192
(default data) and decrease the others.
3) Adjustment mode : Two modes – Medium / Warm
▪ Luminance: 204 Gray
▪ Standard color coordinate and temperature using CS-1000

-. To check the Coordinates of White Balance, you have to
measure at the below conditions.
Picture Mode : select Vivid and change
Dynamic Contrast : Off ,
Dynamic Colour : Off,
Clear White : Off
-> Picture Mode change : Vidid -> Vivid(User)
(If you miss the upper condition, the coordinates of W/B can be
lower than the spec.)
