Configuration of the camera
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 increas-
ing 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.
