Auto shutter control
The table below illustrates the advanced register for auto shutter control.
The purpose of this register is to limit the range within which auto shutter
operates.
When both auto shutter and auto gain are enabled, priority is given to
increasing shutter when brightness decreases. This is done to achieve the
best image quality with lowest noise.
For increasing brightness, priority is given to lowering gain first for the same
purpose.
