    private Field _videoField;
    private Player _player;
    private VideoControl _videoControl;
    byte[] image;

 try{
        _player = Manager.createPlayer( "capture://video??encoding=jpeg&width=240&height=240" );
        _player.realize();
        _player.prefetch();
        _videoControl = (VideoControl)_player.getControl("VideoControl");
        _player.start();               
        if (_videoControl != null){

            _videoField = (Field) _videoControl.initDisplayMode (GUIControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");
            _videoControl.setDisplayFullScreen(true);
            add(_videoField);
        }
    }
    catch(Exception e)
    {
       //show error
    }
         

         try {
                image = _videoControl.getSnapshot(null);
                 _player.close();
               
                EncodedImage bitmap = EncodedImage.createEncodedImage(image, 0, image.length); 
                BitmapField field1 = new BitmapField();
                field1.setImage(bitmap);
                add(field1);
            } catch (MediaException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
