Automatic white balance

The auto white balance feature continuously optimizes the color characteris-
tics of the image.

As a reference, it uses a grid of at least 300 samples equally spread over the 
area of interest or a fraction of it.

AUTOFNC_AOI affects the auto shutter, auto gain and auto white balance fea-
tures and is independent of the Format_7 AOI settings. If this feature is 
switched off, the work-area position and size represent the current active 
image size.

Within this area, the R-G-B component values of the samples are added and 
used as current values for the feedback.

The following drawing illustrates the AUTOFNC_AOI settings in greater detail.
