说说思路..有源码的帖出来看看..
有这方面的源码程序..共享一下..

------解决方案--------------------我见过有人做过,
------解决方案--------------------接分
------解决方案--------------------没接触过,只能顶下
------解决方案--------------------mask
------解决方案--------------------UP
------解决方案--------------------应该要调用windows中的一些函数吧。
------解决方案--------------------用 JMF 估计可以。
------解决方案--------------------//利用这三个类分别获取摄像头驱动,和获取摄像头内的图像流,获取到的图像流是一个Swing的Component组件类
public static Player player = null;
private CaptureDeviceInfo di = null;
private MediaLocator ml = null;
//文档中提供的驱动写法,为何这么写我也不知:)
String str1 = "vfw:Logitech USB Video Camera:0 ";
String str2 = "vfw:Microsoft WDM Image Capture (Win32):0 ";
di = CaptureDeviceManager.getDevice(str2);
ml = di.getLocator();
try
{
player = Manager.createRealizedPlayer(ml);
player.start();
Component comp;
if ((comp = player.getVisualComponent()) != null)
{
add(comp, BorderLayout.NORTH);
}
}
catch (Exception e)
{
e.printStackTrace();
}
下面是获取图像
private JButton capture;
private Buffer buf = null;
private BufferToImage btoi = null;
private ImagePanel imgpanel = null;
private Image img = null;
private ImagePanel imgpanel = null;
JComponent c = (JComponent) e.getSource();
if (c == capture)//如果按下的是拍照按钮
{
FrameGrabbingControl fgc =(FrameGrabbingControl) player.getControl( "javax.media.control.FrameGrabbingControl ");
buf = fgc.grabFrame(); // 获取当前祯并存入Buffer类
btoi = new BufferToImage((VideoFormat) buf.getFormat());
img = btoi.createImage(buf); // show the image
imgpanel.setImage(img);
}
