An image capture device similar to a photocopier. The material to be scanned is placed face down on a glass plate and the capturing device passes beneath the glass. See also: Scanner Last Reviewed: 2003-03-01
An image capture device that is connected to a computer and works in the same way as a photocopier. A moving sensor passes under an image or document that is placed facedown on a glass plate and converts it into a digital file that can be stored on a computer.
An optical scanner in which the original image remains stationary while the sensors (usually a CCD linear array) passes over or under it. The scanned material is held flat rather than being wrapped around a drum.
A scanner/imager that uses a flat surface upon which a physical item is layed to be imaged.
A type of SCANNER which works when an original is placed face-down on a sheet of glass and an arm equipped with a light and an electronic sensor sweeps under the glass. This is the most popular type of scanner for home use; however, it offers limited resolution and limited DYNAMIC RANGE. Contrast DRUM SCANNER.
Any scanning device that incorporates a flat transparent plate, on which original images are placed for scanning. The scanning process is linear rather than rotational.
A device that works similar to a photocopy machine. Used to import graphics and images into a variety of software programs.
A scanner that captures images from photos and drawings placed on a flat glass imaging area. They scan books, photos, fabric, anything that can be placed on the scanner bed.
A type of desktop scanner with a CCD linear array beneath a flat glass surface on which one can lay a whole sheet of paper at once. The scanning-head passes progressively under the glass.
A scanner with a flat, transparent surface that holds the image to be scanned, generally a book or other paper document. A scan head below the surface moves across the image. Some flatbed scanners can also reproduce transparent media, such as slides.
An image-capture device in which the source material remains stationary while the sensor (usually a CCD linear array) passes over or under it. Sometimes called a reflective scanner.
a device intended to capture flat images pressed up against the scanner plate
an eminently affordable optional extra and enables the PC owner to scan into the computer photographs, historic documents and pages of text without retyping
a scanner with a glas plate, on which you have to place a sheet of paper face down
a type of scanner that converts printed materials into digital image
An input device that scans flat objects one at a time.
A desktop or design studio-based scanner that works by placing original artwork face down on a glass sheet and an electronic sensor scans the selected image area and outputs the digital file to a desktop computer.
Scanning is restricted to a single sheet at a time. Useful for damaged / friable paper documents. Significantly lower scanning throughput rates cf ADF scanning.
A scanner with a flat surface that holds the item to be scanned. It is the most flexible type of scanner because it can support various sizes of printed originals, including books and magazines; however, it takes up more space than a sheet-fed scanner. As scanner prices have fallen and become easier to use, flatbed scanners have become increasingly popular. The majority of scanners BestBuy.com carries are flatbed scanners. Some flatbed scanners also offer choices of automatic document feeders and transparency adapters.
A device that scans images in a manner similar to a photocopy machine; the original art is positioned face down on a glass plate.
A scanner which has a flat piece of glass the document is put on to be scanned. One of the problems with a hand-held scanner is keeping the scanner steady; this problem is eliminated with a flatbed scanner because the document is stationary and a mechanically-operated scanning head moves beneath the glass. A flatbed scanner also works better than a sheet-fed scanner when the documents have cut and paste layout that might fall off.
Any scanner with a lid and a large piece of glass that allows you to lay basically any object on it. There are also drum scanners, slide scanners, and other smaller format photo-feed scanners that aren't conducive to ad-hoc stereo imaging of objects around the house.
A flat-surface scanner that allows users to input books and other documents.
This is an optical scanner in which the original image remains stationary while sensors scan the material from beneath the image.
A scanner that works by projecting reflected light onto a CCD chip by means of an optical system. This light is then separated into the primary colors, which are in turn brought together by the scanner to form a digital image. The advantage of this type of scanner is its use of a constant light source. As it can only be used for photographic materials, prints or drawings, the color space of an image can be precisely defined.
A scanner with a flat platen, rather like a photocopier, as opposed to one with a scanning drum.
A somewhat larger version of a film scanner, which reads prints, documents and so on, to convert them into digital data.
An image capture device much like a photocopier. The object to be scanned is placed face-down on a glass plate. The CCD array passes beneath the glass.
A scanner that utilises CCD linear arrays, where the image is placed on a glass platen, and the array moves past the artwork.
Scanner that works similar to a copy machine except it creates a file of a document in memory instead of a paper copy. 5.25
