I've been kicking round the same idea. It doesn't look doable with USB
cause of complexity and speed issues on the master side. The best
answer seems to be to get ahold of the older model rs232 pc cams which
are pretty scarce these days. They're slow enough to be pic-able I
think. Haven't found one so far so haven't any bench experience with
them.

If you want to code an image sensor direct, the Mitsubishi AR has a
fairly long integration time so doesn't look too good with rapidly
moving objects, especially if lighting is bad. The Kodak & Nat Sem dev
boards/eval kits cost arm+leg & Kodak don't seem too keen about free
samples.

Good luck - Ian

PS: USB would be doable if u used a cut down PC card.
Also there's the Linux strongARM kernel which i heard is small enough
to be microprocessable. Don't know anything more 'bout it though.
