camera + arduino + toucheshield

I got a arduino, a touchshield (http://www.liquidware.com/products/show/TS/TouchShield) and a cmos camera lying around (http://www.sparkfun.com/commerce/product_info.php?products_id=8739).

So I was wondering how I would get arduino to display the RCA signal from the camera on the lcd? any ideas?

Yep forget it, it's not fast enough and hasn't got enough memory (ram).
