Charge-coupled Device (ccd)
A charge-coupled device (CCD) is a semiconductor device capable of both photo-detection and memory, which converts light to electronic impulses. One-and two-dimensional CCD arrays are used in scanners to perform the first stage in converting an image into digital data. They are particularly attractive because they can step the signals from each detector across the array in response to a clock signal, permitting each scan line to be read through a single electrical connection.
