Appendix no. 1 – Auto Exposure & Gain Algorithm
The three available auto exposure and auto gain modes are specified in this appendix.
10.1
Auto Exposure Mode
When operating in this mode, the camera tries to reach the desired brightness level of the picture by adjusting
Exposure Time.
Steps to set Auto Exposure Mode:
1.
Define Desired Brightness Level
Figure 12 – Brightness level
2.
Define Auto Exposure Minimum and Maximum Time. These parameters define the limits for exposure
time adjustment. By default, these values will be set to maximum and minimum possible values.

3.
Choose one of Auto Exposure modes: “Once” or “Continuous”. Under “Once” mode, the algorithm will
adjust the Exposure only once and then the feature will be set to OFF. Respectively under “Continuous”
mode, the exposure will be adjusted continuously.
