Charge-coupled device

a semiconductor chip with a grid of light-sensitive elements, used for converting light images, as in a television camera, into electrical signals.
Abbreviation: CCD.
(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 CCD
charge-coupled device
A device made up of semiconductors arranged in such a way that the electric charge output of one semiconductor charges an adjacent one.

(CCD) A semiconductor technology used to build light-sensitive electronic devices such as cameras and image scanners. CCDs can be made to detect either colour or black-and-white. Each CCD chip consists of an array of light-sensitive photocells. The photocell is sensitised by giving it an electrical charge prior to exposure.
