1、下边这个程序是没有Jrame框架的,也就是不是swing界面开发的，是程序在没有人察觉的情况下拍照的，每77毫秒拍一张图片，图片命名为：当前时间的Long毫秒，源码就在下边  自己慢慢看吧！publicclassPhotoGraphextendsThread{  privateCaptureDeviceInfocaptureDeviceInfo=null; privateMediaLocatormediaLocator=null; privatestaticPlayerplayer=null; privateBufferbuffer=null;  privateBufferToImagebu

2、fferToImage=null; publicImageimg; publicImageimg2;  publicPhotoGraph(){  captureDeviceInfo=CaptureDeviceManager    .getDevice("vfw:MicrosoftWDMImageCapture(Win32):0");//这里放置的是视频驱动  mediaLocator=newMediaLocator("vfw://0");//这里是视频地址  DataSourceds=newDataSource();  ds.setLocator(mediaLocator);  try{  

3、 player=Manager.createRealizedPlayer(mediaLocator);   player.start();  }catch(NoPlayerExceptione){   e.printStackTrace();  }catch(CannotRealizeExceptione){   e.printStackTrace();  }catch(IOExceptione){   e.printStackTrace();  } }  publicvoidrun(){  try{   Thread.sleep(3000);  }catch(InterruptedExce

4、ptione){   e.printStackTrace();  }  System.out.println("开始拍照.............................");  Datedate=newDate();  LongdateTime=date.getTime();  while(true){   FrameGrabbingControlfgc=(FrameGrabbingControl)player.getControl("javax.media.control.FrameGrabbingControl");   buffer=fgc.grabFrame();   bu

5、fferToImage=newBufferToImage((VideoFormat)buffer.getFormat());   img2=bufferToImage.createImage(buffer);      FrameGrabbingControlfgcs=(FrameGrabbingControl)player.getControl(                   "javax.media.control.FrameGrabbingControl");           Bufferbuf=fgcs.grabFrame();//获取当前祯并存入Buffer类      

6、     BufferToImagebtoi=newBufferToImage((VideoFormat)buf.getFormat());           img2=btoi.createImage(buf);//showtheimage      this.setImg(img2);   saveImage(img,"G:/photo_test/"+dateTime+".jpg");   try{    Thread.sleep(77);    dateTime+=77;   }catch(Exceptione1){    e1.printStackTrace();   }  } }

7、  /**储存图片 *@paramimage *@parampath */ publicstaticvoidsaveImage(Imageimage,Stringpath){  //下边是图片的大小  BufferedImagebi=newBufferedImage(150,150,BufferedImage.TYPE_INT_RGB);  Graphics2Dg2=bi.createGraphics();
