 Fisheye: In the Fisheye mode, the whole wide-angle view of the fisheye camera is
displayed. This view mode is called Fisheye View because it approximates the vision of a
fish's convex eye. The lens produces curvilinear images of a large area, while distorting
the perspective and angles of objects in the image.
