A charge-coupled device or image sensor. It consists of an integrated circuit with an array of linked ("coupled") capacitors which are sensitive to light. In digital photography, the CCD is used to capture images, which in analogue photography would be captured on film. CCD technology is not only used in digital photography, but also in astronomy and other branches of science.
An image sensor is a type of transducer (an electronic device that converts one type of energy to another). This particular type of transducer converts light (visual images) to electronic signals, in essence capturing images in an electronic form: pixels. Image sensors are used in digital cameras and other imaging equipment and usually consist of an arrangement of charge-coupled devices (CCD).
