What is inside a video camera?
|
|
Inside a video camera, a single charge coupled device (CCD) chip converts the image formed by the lens into a colour video signal, which is recorded onto videotape. An infrared beam focuses the lens automatically, or the user can select manual focus. At the same time the microphones pick up the sound, which is recorded on the edge of the videotape.
