Remarks:
1.
Controls the duration where the photosensitive cells are exposed to light.
6.3.2
Exposure Time
Time in microseconds [µsec] in which sensor is exposed to light. This time is subject to the specified image frame
rate:
minimum exposure ≅ 6
maximum exposure ≅
1,000,000
frame rate
Additional delays might be taken to consideration in calculation of exposure values, like delay between frames,
etc.

Auto Exposure & Gain Algorithm
Auto Exposure and Gain features used to control the picture brightness by adjusting Exposure and Gain values in
automatic mode in order to reach desired brightness level. The algorithm calculates the average picture
intensiveness inside the defined ROI and tries to adjust it to desired brightness level. The brightness is adjusted by
increasing/decreasing exposure time and/or analog gain level. Three modes are available for automatic brightness
adjustment:
6.3.3.1
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 6 – 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.
