charge-coupled device
charge-coup·led device C0248700 (chärj′kŭp′əld)n. Abbr. CCD A photosensitive semiconductor device that transports electric charge from one capacitor to another, allowing serial output of parallel data, typically used for digital image capture.charge-coupled device n (Computer Science) computing an electronic device, used in imaging and signal processing, in which information is represented as packets of electric charge that are stored in an array of tiny closely spaced capacitors and can be moved from one capacitor to another in a controlled way. Abbreviation: CCD charge-coupled device
charge-coupled device See CCD.charge-coupled device[′chärj ¦kəp·əld di′vīs] (electronics) A semiconductor device wherein minority charge is stored in a spatially defined depletion region (potential well) at the surface of a semiconductor and is moved about the surface by transferring this charge to similar adjacent wells. Abbreviated CCD. charge-coupled device (electronics)(CCD) A semiconductor technology used to buildlight-sensitive electronic devices such as cameras and imagescanners. CCDs can be made to detect either colour orblack-and-white. Each CCD chip consists of an array oflight-sensitive photocells. The photocell is sensitised bygiving it an electrical charge prior to exposure.charge-coupled device
