AOI function is only available for color cameras.
The color camera can adjust exposure time and white balance automatically within a certain range
to achieve expected image quality. By default, the camera adjusts the brightness and the white
balance of the whole image. In addition, you can also set an area of interest, which is called AOI.
The camera will adjust the AOI in the image to achieve expected image quality, and the image
quality of area outside the selected region will also be changed.
Regional exposure and regional white balance are generally used in the back light scene or the
scene with the great difference of regional brightness. You can also select rectangle region, and the
camera will adjust the region’s exposure and white balance to achieve the best image quality.

Click Analog Control > Auto Function AOI Selector.
