CCD
A CCD or Charge-Coupled Device is an analog electronic device that can be used as the image sensor in place of film in an electronic camera or scanner. Many digital cameras use CCDs as their image sensor, although some use CMOS or other devices instead. The CCD was invented in 1969 at Bell Labs by Willard Boyle and George Smith. Whilst the CCD is sensitive to light - and so can be used as an image sensor, it has also been used as a memory device.
