CASE Cool
First adjust the coordinate far away from the target value(x, y).B
1. x, y 〉target
2. x, y〈 target
3. x 〉target , y〈 target
4. x 〈 target , y 〉target
1. x, y 〉target
2. x, y〈 target
3. x 〉target , y〈 target
4. x 〈 target , y 〉target
- Every 4 case have to fit y value by adjusting B Gain and then fit x value by adjusting
R-Gain
- In this case, increasing/decreasing of B Gain and R Gain can be adjusted.
How to adjust
1.Fix G gain to 172
Adjust R Gain and B Gain ( In Case of Mostly Blue Gain Saturation )
2.When B Gain > 255, Release Fixed G Gain and Readjust

ⅰ
) Decrease the R, G.
2. x, y〈 target
ⅰ) First decrease the B gain,
ⅱ) The one value is bigger than the target then the other one should be not much more

bigger than target.
Ⅲ
) In case that we take x off, we also take R (G-gain fix)
In other case that we take y off, we also take G (R-gain fix)
3. x 〉target , y〈 target
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
