I'd recommend starting with the white paper about 2013 vision processing.

The camera and other code doesn't "know" what it is looking at. You can use it to capture an image, and you can use what is known about the targets and your setup to process the image and determine if the target is in the image, where, how far away, etc. But the first step is to read the paper and ask questions that are more technical than what the printf says.
