ng-camera

Ng-camera is an AngularJS directive for capturing images form your computer's camera, and delivering them to you as Data URIs. The images is transmitted to your AngularJS controller and can be modified like you want.

To manage this process, ng-camera uses the WebcamJS standalone Javascript library developed by Joseph Huckaby, to ensure fallback and crossbrowser requirements.
