This is half true. What you are seeing is just the sensor. There is no lense on it. Also, what use would a camera be without light? You need a light source close to the camera to be able to see anything with it. The 200x200 resolution is barely enough to do anything with; it takes big CPUs to register the images, to estimate ego motion and produce 3D models. Not something you can do without a dozen pounds of further equipment.
