A scanner captures images from photographic prints,
posters, magazine pages, and similar sources for computer editing and
display. Scanners come in hand-held, feed-in, and flatbed types and for
scanning black-and-white only or color. Very high resolution scanners
are used for scanning for high-resolution printing, but lower resolution
scanners are adequate for capturing images for computer display. Scanners
usually come with software, such as Adobe's Photoshop product, that lets
you resize and otherwise modify a captured image.
