* CASE

First adjust the coordinate far away from the target value(x, y).
1) x, y > target

i) Decrease the R, G. 

2) x, y < target

i) First decrease the B gain, 
ii) Decrease the one of the others.

3) x > target, y < target

i) First decrease B, so make y a little more than the target.
ii) Adjust x value by decreasing the R

4) x < target, y > target

i) First decrease B, so make x a little more than the target.
ii) Adjust x value by decreasing the G

(4) Standard color coordinate and temperature when using the

CA100+ or CA210 equipment

To check the Coordinates of White Balance, you have to
measure at the below conditions.
Picture Mode : User 1
Dynamic Contrast : Off
Dynamic Colour : Off
(If you miss the upper condition, the coordinates of W/B
can be lower than the spec.)
