How S
CANNERS
All scanners convert areas of light and dark into
digital data for your computer. One of the most
versatile scanners for general office use is the
flatbed scanner. Scanning an image on a flatbed
scanner is a lot like using a photocopier. Here's
how it works:
You place your document (a photo, book, or any
image that you want to scan) face-down on the
glass and close the cover.
Using the scanner software, you select a few
2
simple settings to adjust the way the image will
be captured; then you scan the document.
Inside the scanner, a light bar moves over the
3
image and the reflected light falls on a bed of
photosensitive cells. The cells "read" the image,
interpreting it as a series of tiny dots. Each dot
is called a pixel, or picture element. The carriage
scans one line of pixels at a time.
The software converts the values of each pixel into
4
data that the computer can understand. When the
entire document is scanned, the resulting image
appears on your monitor.
You can print the image as it appears on-screen
5
or you can manipulate it with image editing or
graphics software to get the results you want.
