What does "3 CCD" mean?

3 CCD refers to a feature that is rapidly becoming more and more common amongst digital imaging devices; it is the arrangement of three independant CCDs behind a prism which separates the light into its red, green, and blue components: each component strikes a separate CCD thus eliminating color pollution which is a common cause of image quality loss in signle CCD based devices.

Here is a little ASCII picture:

                                  /\  ------ Red --->  *** (Red CCD)
--- Light from Image --->        /  \ ------ Blue -->  *** (Blue CCD)
                                /____\ ---- Green -->  *** (Green CCD)

The prism is either mounted in the lens or in the body.
