GigE Area Scan Camera User Manual
If there is still great difference between correction effect and actual color, it is
recommended to correct white balance according to following steps.
Steps
Note
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 device, 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.
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 device’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.
12.19 Set Gamma Correction
Note
The Gamma correction function may differ by device models.
Regarding the color device in Bayer pixel format, you need to enable Super Bayer Enable
first before using Gamma correction function.
The device supports Gamma correction function. Generally, the output of the device’s
sensor is linear with the photons that are illuminated on the photosensitive surface of the
sensor. Gamma correction provides a non-linear mapping mechanism as shown below.
Gamma value between 0.5 and 1: image brightness increases, dark area becomes
brighter.
Gamma value between 1 and 4: image brightness decreases, dark area becomes darker.
