From your camera specs I assume that you have a composite video output camera. So you should best use an FPGA board with a video codec on board. The de2 board (http://de2.terasic.com)is an excellent platform for your project. The board also has worked out examples using such a camera. You should of course update the provided designs for your project.

The relation of your composite video camera with the (incomplete) block diagram that you have drawn is unclear.
