I am using Phonegap. Is there any method to display开发者_如何学运维 image or button or circle on top of camera preview. I am also using Sencha Touch.

I think not without programming native, ie objective-c for iphone. What device do you target?

On iphone you can add a cameraOverlayView to the UIImagePickerController.
