It is recommended to correct white balance when there is great difference between the camera's
color effect and actual effect. You can correct white balance as shown below.
Steps:
1. Put a white paper in the range of the camera's field of view, and make sure the paper covers
the entire field of view.
2. Set exposure and gain. It is recommended to set image brightness value between 120 and 160.
3. Select Once as Balance White Auto, and the camera will automatically adjust white balance
for once.
If there is still great difference between correction effect and actual color, it is recommended to
correct white balance according to following steps.
Steps:
1. Select Off as Balance White Auto. At this time, Balance Ratio is 1024.
2. Find corresponding R/G/B channel in Balance Ratio Selector. Here we take Green as an
example.
3. Find camera's R/G/B value.
4. Take Green as correction standard, and manually adjust other two channels (R channel and B
channel) to let these three channels have same value.
 Here we take Green as an example. For specific Balance Ratio Selector value, please refer to
the actual condition.
 In order to avoid repeated correction after rebooting the camera, it is recommended to save
white balance parameter to User Set after white balance correction. You can refer to the
Section Save and Load User Set for details.
 If the light source and color temperature in environment change, you need to correct white
balance again.
