Charge-Coupled Device
     
        (CCD) A semiconductor technology used to build light-sensitive
        electronic devices such as cameras and image scanners.  Such
        devices may 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.
