The CCD is the Charge Coupled Device. It is a light sensor that sits behind the lens in digital cameras. It records the image when you take a photograph. It is a grid made up of millions of tiny light sensors. The capacity of the CCD is measured in megapixels. The higher the number of megapixels the higher the resolution of the picture.
