Correct exposure time (shutter speed) influences the quality of the extracted edges. To
control the exposure time / brightness, you can use the parameters Shutter speed and
Brightness.
The shutter speed / brightness must be set to obtain the optimum contrast. The automatic
exposure control can help to achieve the optimum shutter speed setting.
Below, you will find examples of different shutter speeds and disturbing contours:
