AUTOFNC_AOI affects the auto shutter, auto gain and auto white balance features and is

independent of the Format7 AOI settings. If this feature is switched off the work area position

and size follow the current active image size.

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

fraction of it. The position and size of the control area (Auto_Function_AOI) can be set via the

following advanced registers.
