Description of the data path
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 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.
Note
Configuration
To set position and size of the control area (Auto_Func-
tion_AOI) in an advanced register: see Table 116: Advanced
register: Autofunction AOI on page 214.
Note
If the adjustment fails and the work area size and/or position
becomes invalid this feature is automatically switched off -
make sure to read back the ON_OFF flag if this feature doesn't
work as expected.
