+<h1>Image Capture Overview</h1>
+
+ <p>The capture support is designed for live video, it is not for passive
+ digital cameras that only transfer the already taken pictures. Are valid: USB
+ cameras (like most Webcams), Firewire (IEEE 1394) cameras, and analog video
+ capture boards, including TV Tuners. These are called devices.</p>
+ <p>The capture functions allows you to:</p>
+ <ul>
+ <li>list the available devices</li>
+ <li>connect to a device</li>
+ <li>configure the device</li>
+ <li>retrieve an image</li>
+ </ul>
+ <p>You can list the installed devices and once you connect to a specific
+ device you can control its parameters. Each connected device captures data
+ frames continuously when in Live state otherwise it stays in standby. You can
+ connect to more than one device at the same time. </p>
+ <p>Once connected the user can retrieve frames from the device any time. This
+ can be done with one function call, or inside a closed loop for several
+ frames, or inside an idle function to periodically update the screen. The user
+ is not notified when a new frame is available, but every time the user
+ retrieve a frame, if successful, it is a new frame, old frames are discarded
+ when a new frame arrives.</p>
+ <p>Currently it is implemented only in Microsoft Windows. </p>
