Understanding Scanner Technology

Most scanners work by reflecting light off of an object and detecting the reflected light with a charge-coupled device (CCD). Stated this broadly, scanners are no different from digital cameras. In practice, scanners usually take longer to form an image because their CCDs can't take in the entire image at once. Instead, the scanner builds up the image as its CCD views one part of the page after another. Precisely how the scanner shifts its point of view varies from one device to another. These variations form the basis of the major classifications of scanners.
