Why when most of these are one chip sensors, and a lot of the Omnivision
chips can then have Marshall's board camera lens fittings to go over the
chip and have choice of lens to fit, which are cheap!

Define raw image data? This could be all sorts of things as RAW data be
anything from colour filter signals or differences between adjacent sites
up to formatted data signals. They can analog or digital depending on
the device being used, CCDs are predominantly analog, CMOS sensors are
predominantly digital.
If you are not doing board layout how are you going to get the data to
a Spartan 3 FPGA?

MOST webcams are not VGA resolution they are smaller.

Try Marshalls <http://www.mars-cam.com/optical.html>
Try even getting hold of camera and evaluation kits from Omnivision

Image processing is a lot of things from adjusting black level or gain to
rotating or fourier transforms of images, what do you men by image processing?
