+\title Camera Example
+\ingroup camera_examples
+\brief The Camera Example shows how to use the API to capture a still image
+or video.
+
+
+
+The Camera Example demonstrates how you can use QtMultimedia to implement
+some basic Camera functionality to take still images and record video clips
+with audio.
+
+A Camera class is created that will act as our Camera. It has a user interface,
+control functions, setting values and a means of defining the location where
+the image or video clip is to be saved. It will also store the image and video
+settings.
+
+The Camera class contains an instance of \l {QCamera}, the API class interface to
+the hardware. It also has an instance of \l {QCameraImageCapture} to take still images
+and an instance of \l {QMediaRecorder} to record video. It also contains the user
+interface object.
+
+The Camera constructor does some basic initialization. The camera object is
+set to '0', the user interface is initialized and UI signal are connected to
+slots that react to the triggering event. However, most of the work is done when
+the \e{setCamera()} function is called, passing in a \l {QByteArray}.
+
+\e{setCamera()} sets up various connections between the user interface and the functionality
+of the Camera class using signals and slots. It also instantiates and initializes the \l {QCamera},
+\l {QCameraImageCapture} and \l {QMediaRecorder} objects mentioned above. The still
+and video recording visual tabs are enabled and finally the
+\l {QCamera::start()}{start()} function of the \l{QCamera} object is called.
+
+Now that the camera is ready for user commands it waits for a suitable event.
+Such an event will be the key press of either the \l {Qt::Key_CameraFocus} or
+\l {Qt::Key_Camera} buttons on the application window. Camera focus will
+simply display the viewfinder and lock the camera settings. Key_Camera will
+either call \e{takeImage()} if the \l {QCamera::captureMode()}{captureMode()}
+is QCamera::CaptureStillImage, or if the capture mode is for video then one
+of two actions will occur. If the recording state shows that we are currently
+recording then the \e{stop()} function is called resulting in a call to
+\l {QCamera::stop()}, whereas if we are not recording then a video recording
+is started with a call to \l {QMediaRecorder::record()}.
