About Image Scanners
Image scanners are devices that scan two-dimensional (2D) objects and convert them into digital images. They often use a charge-coupled device (CCD) or contact image sensor (CIS) as their imaging-sensing component. Most image scanners read red-green-blue (RGB) color from an array, and then transfer the scanned image to a computer. Product specifications include the way in which the image scanner physically connects to the computer, and the way in which data is retrieved from the scanner. Connection types for image scanners include parallel, small computer systems interface (SCSI), universal serial bus (USB), and IEEE 1394 or FireWire (Apple Computer).
There are many types of image scanners. Examples include drum scanners and flatbed scanners. Drum scanners use upon photomultiplier tubes (PMT) instead a CCD or CIS. Operators place the object to be scanned upon a large, glass drum with an acrylic cylinder that rotates at high speeds. The ability to control aperture and sample-size make drum scanners a good choice for applications that require the enlargement of originals. Unlike drum scanners, flatbed scanners use CCDs and a flat glass pane called a platen. A xenon or cold cathode fluorescent light is used to illuminate the pane. Color flatbed scanners are image scanners with separate sensor arrays with red, green, and blue filters.
