I am using Phonegap with Sencha Touch to get camera functionality. But instead of the default camera view, I want a picture with transparent background to be overlaid upon the live camera view. Similar to below example where a dinosaur image has been overlaid upon the camera view image.
Can you tell me whether this feature can be achieved with Phonegap or in any other way?
It can be achieved but it requires a bit of native code and a simple trick.
You need to set the phonegap container to transparent, and also add a surface behind your phonegap container.
You use native code to initialize the camera view and then phonegap renders atop of it.
A good example can be found at: http://git.libresoft.es/ARviewer-phoneGap/
