Charge Coupled Device......(VIDEO CAMERAS)
3CCD Cameras
CCD (Charge Coupled Device) A microelectronics chip which stores minute electric charges on a matrix of micro-capacitors. These voltages are bucketed (in the sense of a bucket brigade) from one address to another according to an external-clocking signal. This permits storage of analog memory on the chip. CCD technology is used in audio to store a signal, which can be retrieved later to create an echo effect via retrieval delay. In video, CCDs are at the heart of video cameras. Lenses cast a beam of light on the CCD, which acts as a sensor and temporarily stores the visual image. CCDs were used to store a video signal, which was later retrieved for time base correction*. Digitally storing video information is performed nowadays using fast RAM chips.
