VIDEO CAMERA
A camera which contains an electronic image sensing CCD (Charged Coupled Device) rather than photographic film. The CCD is scanned rapidly converting light rays to electric signals. A video camera has additional electronic circuitry which generates color and sync pulses. Some cameras are equipped with audio circuitry, e.g., microphone, audio amplifier and additional audio electronics. Professional cameras, in order to obtain a better picture, have a triple CCD system (three tubes in the past) - one for each basic color - red, green and blue. Most professional cameras have a genlocking input, which allows the camera to be synchronized to an external source. Some cameras include additional electronic circuitry such as character generators for titling and special effects, Tally, etc. CMOS type sensors are also used for some types of cameras. Those sensors are relatively inexpensive to manufacture.
