  charge-coupled device
  
     <electronics> (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.
