This is dependant on the camera system. We need a signal from the camera sensor to calculate on. But that signal can be so weak that the unprocessed material is completely black. However, when the lighting situation turns that bad the camera might run into other problems, for instance the auto focus tends to fail. An out of focus image will still be blurry after our processing.
Also, in low light situations the camera sensors often generate a lot of video noise, which is visible in the processed material. However, it is still possible to interpret and identify objects in the image, which is a very important feature in many video applications. And we do this in colour, where other low light technologies generate a monochrome image.
