<div class="descr"> <a name="details"></a>
<p class="centerAlign"><img src="images/qml-camera.png" alt="" /></p><p>This example demonstrates how to use the <a href="qtmultimedia-qmlmodule.html">Qt Multimedia QML API</a> to access camera functions. It shows how to change settings and to capture images.</p>
<a name="running-the-example"></a>
<h2 id="running-the-example">Running the Example</h2>
<p>To run the example from Qt Creator, open the <b>Welcome</b> mode and select the example from <b>Examples</b>. For more information, visit Building and Running an Example.</p>
<a name="application-structure"></a>
<h2 id="application-structure">Application Structure</h2>
<p>Most of the QML code supports the user interface for this application with the camera types being mostly found in <i>declarative-camera.qml</i> and <i>CaptureControls.qml</i>.</p>
<p>CaptureControls, which is implemented in <i>CaptureControls.qml</i>, generates a column on the right hand side of the screen which includes control buttons for focus (not initially visible), capture, flash modes, white balance, exposure compensation, and if a preview is available, a preview button. The last button exits from the application.</p>
