|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.
