The Viewer allows the possibility of having the Exposure and ADC Gain auto controlled according to
the illumination.

●
Apply AEC
●
The Automatic Exposure Control (AEC) is activated
●
When the sensor is saturated, Exposure and Gain will decrease until the image is not
saturated. On the other hand, if the image is too dark, Exposure and Gain will increase
until the image is bright enough, not saturating.
●
Show ROI
●
When enabled, shows the area in which the AEC retrieves the DN values to perform the
algorithm.
●
On the bottom of the image there are four blue lines, which represents the Gain (each
line a Gain step value, where the top one represents the highest value), and a yellow line
Exposure value (increasing from left to right).
●
Region of Interest
●
These values represent the area (rows and columns) that the algorithm uses to check if
there is a need to update the sensor registers
●
Target
●
Algorithm’s DN target value. The lower it is, the darker the image will be. The higher it is,
the brighter the image will be.
●
Hysteresis
●
Defines the thresholds (superior and inferior limits) where the AEC algorithm works. Each
time the region of interest reaches an average DN value higher/lower than the limits, the
algorithm will converge to the target DN value.
