How to directly capture images from a built-in webcam in a web application?

Question

I already have a web application that allows my clients to scanner documents from scanners with TWAIN drivers installed, save scanned documents as PDF locally or upload to web server.

One thing I would like my web application to support is capturing images from built-in webcam. It seems there aren't or very few webcams that support TWAIN.

Any suggestions to make it work?

You'll need to use something other that TWAIN, WIA is probably the easiest way to grab an image, see this answer
