What Is a Document Scanner?
A document scanner is an intriguing device. By simply laying an existing, physical document on a flatbed scanner (or passing it under a hand-held scanner), an entire document can be quickly and easily input into a computer, stored as a picture, or even read into a word processing program. This article will explore how this process works, types of scanners, benefits and use. Function In its most basic form, a document scanner is very much akin to a stationary digital camera. When a document is placed on the scanner (or passed under it for hand-held models), the scanner creates a digital image of the document much the same way a digital camera or photocopier works–by reflecting light off the document and recording the incoming reflections as digital images. These digital images are then fed to corresponding software applications on a connected computer, where the image is saved as a picture file (like a JPEG or Bitmap image), converted into an Acrobat-readable PDF file, or interpreted f
