cmos image sensor to usb



Hello,
I'm working on a personal project where I'd like to basically make my
own webcam from scratch. I am looking for a camera in the VGA/15fps
range. The most important factor in my design is form factor. I'd like
to make it as "pencil-like" as possible. For example, I basically want
something like this:
http://www.aurora-optical.com/modules/CM036U%20Preliminary%208-8-07.pdf
from Aurora Optical, but I want to be able to put the sensor on a flex
circuit and have the processor/USB chip behind the sensor. Can anybody
out there help point me in the right direction? I have a EE background,
but no experience with image sensors or USB. I've looked at the OV511 USB
bridge, but in general, I haven't found much documentation on a complete
sensor-to-USB solution. Would this be a relatively straightforward
design? In other words, if I want my own "thin" form factor, what
components do I need to go from sensor-to-USB as easily as possible? Are
there any good resources on "howto build a webcam?" I've looked, but I
haven't found much.

Thanks in advance!
Mike
