Before you start, you need to get the Microsoft.Phone.Media.Extended.dll and GAC it. For more information on this, read this and this!
Let’s Start
Create a new Windows Phone application, add the Microsoft.Phone.Media.Extended.dll reference and add the ID_CAP_CAMERA
capability to the WMAppManifest.xml.

In our main window, we need to add a CameraVisualizer
<phone:PhoneApplicationPage
x:Class="WindowsPhoneApplication1.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:media="clr-namespace:Microsoft.Phone;assembly=Microsoft.Phone.Media.Extended"
mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}"
SupportedOrientations="Portrait" Orientation="Portrait"
shell:SystemTray.IsVisible="True">
<Grid x:Name="LayoutRoot" Background="Transparent">
<media:CameraVisualizer x:Name="cameraVisualizer" />
</Grid>
</phone:PhoneApplicationPage>
This is used to show the actual images captured from the camera. Next, setup the camera
VideoCamera camera = new VideoCamera();
cameraVisualizer.SetSource(camera);
And that is it!
NOTE: Do not run this in the emulator... It will crash!!!
Is their any practical uses for this? Sure, Kevin Marshall (from Clarity consulting) has a excellent demo of this being used for reading barcodes and for augmented reality!
This is a MUST READ article....
