This device use a charge-coupled device (CCD) as its sensor. A CCD is a photosensitive chip that converts a pixel, or picture element, in a still image to an electrical charge. This charge?s intensity is directly equivalent to an equivalent color in the color spectrum. Some CCDs recognize up to 65,535 separate colors, and each color has an equivalent electrical charge. CCDs is a major part of digital imaging and is widely used in scanners, cameras, even in astronomical instruments, such as telescopes.
