Yep, it is possible to invoke native camera app (google for it, there should be some examples in web). To retrieve captured image you should add some QFileSystemWatchers and set them to folders where camera saves photos.

You can use QtMobility [doc.qt.nokia.com] package.

Here is the reference to QCamera [doc.qt.nokia.com] class

Many thanx for your reply.
I forget to mention one thing I have developed the front end using qml. So can you provide me some information how to relate your reply with the qml.

Again Thnx in advance :)

May be you are looking for some thing like this [doc.qt.nokia.com]. :)
