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?

Answer 1

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

Answer 2

If your camera does not have a twain driver and your applications are not "seeing" it, you will have to use a 3rd party solution that comes in between the camera and your application. I am using terminalworks' Unitwain as I am already using some of their other scanning products. I must say that it helped me a lot cause I already had a lot of web cameras installed but no twain drivers available for our new business application.
