Image Systems have a 3-step process... Image
Capture, Process and Output.
Capture involves using a digital camera, or scanner
to capture light information, convert it into a series of
numbers, and then store those numbers in an picture file.
Processing involves using computer software to change
the numbers that were created in the capture process.
Image Output involves converting the numbers
in the picture file back into a form that can be recognized
as the picture originally taken
