cctv project

I would like to connect a camera (video) to the arduino , and i would like to arduino to storage the image somewhere and to do an image processing.

This is the first time which i would like to do a video project and i have not idea how to do it? Can anyone help me ?

Well, taking and storing an image via a JPEG camera is doable. Extracting an image from the JPEG data and doing "an image processing" is not really a job for a simple, slow eight bit micro controller.
