Remarks

The region of interest specifies the rectangular area of preview that functions such as focus and exposure are computed over. This enables scenarios such as tap to focus.

You can access the RegionsOfInterestControl for the capture device through the MediaCapture.VideoDeviceController.

For how-to guidance for using the RegionOfInterest object, see Effects for analyzing camera frames.
