Scanners and Digital Cameras
There are two primary ways to translate images into a computer-compatible format:
A scanner has a clear glass window like on a copy machine.
However, instead of copying
something on a piece of paper to another piece of paper it copies what's on a
piece of paper then translates it into a digital image (see below), which can be
understood by computers.
Unlike a scanner (which translates an existing image into binary format), a digital camera
records an image in digital format directly.
A digital image is
stored on a magnetic media (in the digital camera) from the moment it's created.
Most digital cameras have the ability to "download" the images from
the magnetic media in the camera itself to your computer.

A digital image is one that is stored in a
format that can be understood by computers. This allows it to be:
- stored on a computer (on diskettes, your hard drive, CD's, etc.)
- displayed on a computer screen in a web page or graphics program, or
- sent electronically over the Internet in email
