What is a scanner used for?
For computer editing and presentation, a scanner is a device that extracts pictures from photographic prints, posters, magazine pages, and other sources. Using optical character recognition, scanners turn the image on a page into digital data that can be saved on a computer (OCR).
What is OCR?
The procedure used to transform an image of text into a machine-readable text format is known as optical character recognition (OCR). Your computer will save the scan as an image file, for instance, if you scan a form or a receipt.
A scanner is a vital tool for converting physical documents into digital data. It allows you to easily save, edit, and share documents in various electronic formats. Understanding how scanners work can help you utilize this technology to its full potential.
How does a scanner work?
1. The glass scanning plate is topped with the object to be scanned.
2. The logic board receives instructions from the computer regarding how fast and how far the motor should go.
3. The scanning device is put into the proper position according to the logic board instructions so that scanning can start.
4. The pace at which the scanning unit traverses the image to be scanned is determined by the logic board command.
5. A light source shines on the image while the scanning equipment moves across it.
6. A sequence of mirrors reflect the light after it strikes the image, which is then reflected back to the scanner lens.
7. The CCD sensors receive the light after it travels through the scanner's lens.
8. An ADC, or analog to digital converter, converts the analog voltage to digital values.
9. The logic board receives the digital signals from the CCDs and transmits them back to the computer.
By following these steps, a scanner can accurately capture and convert physical documents into digital files that can be easily manipulated and stored.
