Banner PresencePLUS P4 COLOR Series - Manual (Page 36)

Draw the WB ROI on a region of the image known to be white. This routine will automatically adjust the gain for
each of the R, G, and B channels in an effort to make the area in the WB ROI appear white. Strange effects can
occur if the area in the WB ROI is not in fact white as shown below when white balancing on blue. This effects
will carry over to the gray scale version of the image too.
