A scanner is a device that converts images, printed text, or
handwriting to a digital
image..
The flatbed scanner is the most common in offices. Hand-held scanners, where the
device is moved by hand, were briefly popular but are now not used much.. Both
these types of scanners use charge-coupled device (CCD) or Contact Image Sensor
(CIS) as the image sensor, whereas older drum scanners use a photomultiplier . Rotary scanner
-- a kind of drum scanners -- are used for high-speed document scanning. uses a CCD array instead
of a photomultiplier. Planetary scanners, take photographs of books and
documents, and 3D scanners, for producing three-dimensional models of objects
Another category are digital camera scanners,. while still containing disadvantages
, offer unmatched advantages in speed and portability
