Balance White Auto (Color Cameras)
The Balance White Auto feature is implemented on color cameras. It will control the white balance of the image
acquired from the color camera according to the GeryWorld algorithm. Before using the Balance White Auto
feature, you need to set the Data ROI for Balance White Auto. If you do not set the related Data ROI, the pixel
data from the Image ROI will be used to control the white balance. As soon as the Balance White Auto
parameter is set to Once, the Digital Red, Digital Green and Digital Blue will be set to 1. Then, Digital Red and
