Detailed Description

The QCameraImageCapture class is a high level images recording class. It's not intended to be used alone but for accessing the media recording functions of other media objects, like QCamera.

 camera = new QCamera;

 viewfinder = new QCameraViewfinder();
 viewfinder->show();

 camera->setViewfinder(viewfinder);

 imageCapture = new QCameraImageCapture(camera);

 camera->setCaptureMode(QCamera::CaptureStillImage);
 camera->start();
 //on half pressed shutter button
 camera->searchAndLock();

 //on shutter button pressed
 imageCapture->capture();

 //on shutter button released
 camera->unlock();
