Scanner

  • Definition: a device that enables a computer to read a printed or handwritten page. The simplest scanners give the contents of the page to the computer as a graphic imageā€”a handy way of putting pictures into the computer. There are many nuances involved in scanning artwork. In some ways, it is quite similar to photography and if you are comfortable with a camera, it will make the transition to working with a scanner very smooth. Scanners can adjust the contrast and brightness of the image. Controls for setting the highlight and shadow area are usually provided. Color images can be color-corrected at the scanning stage. With appropriate software, scanners can read the letters of typewritten text, transmitting them into the computer as if they were typed on the keyboard (OCR). This process, however, is seldom 100% accurate. You will find it necessary to proofread scanned copy very carefully.
