+\title QML Camera Example
+\ingroup camera_examples_qml
+
+\brief  The Camera Example shows how to use the API to capture a still image
+or video.
+
+\image qml-camera.png
+
+This example demonstrates how to use the Qt Multimedia QML API to access
+camera functions. It shows how to change settings and to capture images.
+
+Most of the QML code supports the user interface for this application with the
+camera types being mostly found in \e {declarative-camera.qml} and
+\e {CaptureControls.qml}.
+
+In \e {declarative-camera.qml} the \l Camera is initialized with an id
+of \e {camera}, a photo preview is setup, states are implemented for image
+preview or capture and \l CaptureControls is initialized. The initial
+\e state is \e PhotoCapture. \l CameraCapture includes a handler, \e onImageCaptured,
+for the \l {imageCaptured} signal. The handler sets up the application to process
+the preview including a change in the user interface state. The \l PhotoPreview
+becomes visible with any key press being picked up by the handler
+in PhotoPreview and returning the state to \e PhotoCapture.
+
+\e CaptureControls, which is implemented in \e {CaptureControls.qml},
+generates a column on the right hand side of the screen which includes control
+buttons for \e focus (not initially visible), \e {capture}, \e {flash modes},
+\e {white balance}, \e {exposure compensation}, and if a preview is
+available a \e {preview} button. The last button exits from the application.
+
+When the Capture button is pressed the \e onClicked handler calls
+\l {Camera::captureImage()}{captureImage()}
