You've connected the camera to the Arduino in some mysterious fashion.
You've compiled, linked, and uploaded some mysterious code to the Arduino.
What the code does is a mystery.
What you expect it to do is a mystery.

Sorry, too many mysteries going on here. Agatha Christie couldn't unravel them all.
