Finally, the calculated correction values can be read from the
WHITE_BALANCE register 80Ch.
Automatic white balance
The auto white balance feature continuously optimizes the color characteris-
tics of the image.
For the white balance algorithm the whole image or a subset of it is used.
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 will follow the current active
image size.
Within this area, the R-G-B component values of the samples are added and
used as actual values for the feedback.
The following drawing illustrates the AUTOFNC_AOI settings in greater detail.
