- A scanner is a device that copies a picture in digital form. After capturing the image, the data is transferred to the computer.
- People use scanners to store their hand held pictures in their computer, and one might scan a document for business, school, etc.
- The two main types of scanners are flatbed and portable scanners.
- A flatbed scanner is the most common type of scanner, and it is designed to scan flat objects.
- A portable scanner is designed for travel purposes.
- A sheet fed scanner is much like the flatbed scanner, only this may now be immobile and be used in stores to scan items on shelves.
- Optical scanners capture the image of a usually flat object and transfer it to a computer, much like flatbed scanners. In order to produce a better quality image, as most people strive for in their printing, you need a higher resolution scanner.
- The resolution of a scanner is measured in dots per 12-inches, which makes sense because the more dots you have, the more color that shows up, producing higher quality scans.
- Along with the resolution of a scanner comes the quality, which can be edited and improved once the image is scanned. If the user wants an extremely detailed scan, the drum scanner is a great tool to make this possible.
- It uses a photomultiplier tube to scan on a glass cylinder and send light rays in three beams, making light and color change and producing greatly detailed images.
- There are even apps on our phone that we can personally scan documents to have on-the-go. The problem with this, however, is privacy issues and the crisis of having your phone or any other device stolen which has scanned any personal information.
- While scanners are a tremendous help especially in businesses, it is important users be aware of the risks and use with caution.
- Although digital cameras are considered standard today, many individuals still have negatives from their days of using a film camera.
- This traditional film can easily be digitized using a specialized film scanner. Increasing the resolution will allow for higher quality reproductions of the images.
