Sensor system: Tube/CCD

The charge coupled device (CCD) is a solid-state device which has rapidly replaced the conventional camera pick-up tube (Plumbicon and Saticon). Both the CCD and the camera tube use a light-sensitive material which changes its resistance when light falls on it (photo-conductive). The optical image on the sensor therefore results in an electrical charge pattern being formed which is processed in the camera to produce the video signal. The CCD is a special integrated-circuit and is often referred to as a ‘chip’ camera.

Camera configuration

Video cameras may use either a single device to generate the video signal, or a three-path system.

Single-sensor cameras. These use a single device to convert the ...
