How do scanners work?

Scanners operate by shining light at the object or document being digitized and directing the reflected light (usually through a series of mirrors and lenses) onto a photosensitive element. In most scanners, the sensing medium is an electronic, light-sensing integrated circuit known as a charged coupled device (CCD).

Is a scanner necessary?

Now, for the majority of people who are just going to be scanning things on occasion, then a scanner might not necessarily be worth it. Unless you pick up a small portable scanner that is, but even then they can be a little bulky to carry around with you. So for convenience, sticking with a camera is a good idea.

As a maker of document-capture devices, we get these questions pretty often – especially since we manufacture products that use both kinds of cameras. Simply put, a line scan camera is a strip that captures one row of pixels at a time in quick succession, while either the camera is moved over an object, or the object is moved under the camera.

What is the difference between an area scan and line scan?

An easy way to visualize the difference is that a regular, area scan camera takes a single picture of a square or rectangle all at once, while a line scan camera would take hundreds of 1D pictures in a row and form them into a picture of that same 2D area.
