What is scanning?
Scanning an image is like a copier copying an image. The major difference is that
the output of the scanning is an electronic file which can be edited by software
and stored in disk.
How does the
scanner work?
When scanning, the scanner applies a light source to the image. The light is
reflected back from the image into a CCD (Couple-Charged
Device), where the varying levels of light are interpreted and digitized. The
image is then reconstructed and displayed on your screen.
How do you
get the right image from the scanner?
First, you should find the answers to the following questions:
- What is the scanned image for? For a document? For printing out? To be viewed on the
screen or converted into text by OCR?
- What image-editing software will be used and what file formats does it accept?
- What is the original image type and what type should be applied to the scanned
image?
What can you do with a scanner?
- Optical Character Recognition (OCR) - You can convert text-based images like a fax into
text that can be edited by a word-processing software.
- Enrich your presentations and documents by adding images.
- Convert hard-copy images or documents into a fax format for faxing.
- Add scanned images to your e-mail to enrich your content.
