2. Min Exposure Time [
not match the minimum exposure time of the image sensor, but should not undercut.
3. Max Exposure Time [
must not match the maximum exposure time of the camera, but should not exceed.
4. Exposure Time Threshold [%] (default 10): absolute difference between new exposure and old
exposure value. The new calculated exposure value needs to be higher than this threshold value to
be considered as the new exposure to be adjusted.
