Auto Exposure & Gain ROI Definition
ROI definition refers to Region of Interest which will be used for brightness calculations. The ROI Offset X and
Offset Y refer to the distance of the ROI from top left corner of sensor area:
Figure 19 – ROI position in relation to the origin
By default, ROI defined to be maximum possible area, i.e. the horizontal and vertical offsets are 0 and the ROI
width and height as the sensor dimensions. The ROI settings for brightness calculations could be modified under
section Analog Control->AutoCompensationControl:
