运用的是开源项目webcam-capture实现的；

基本的示例比较齐全，上手快。

**webcam-capture项目地址： [https://github.com/sarxos/webcam-capture][https_github.com_sarxos_webcam-capture]**

###    **使用webcam-capture写了个拍照的小demo，代码如下：** ###

/**
     * 相机测试
     */
    public class TestWebCam {
    
    	private static JFrame window;
    
    	public static void main(String[] args) throws InterruptedException {
    
    		Webcam webcam = Webcam.getDefault();
    		webcam.setViewSize(WebcamResolution.VGA.getSize());
    
    		WebcamPanel panel = new WebcamPanel(webcam);
    		panel.setFPSDisplayed(true);
    		panel.setDisplayDebugInfo(true);
    		panel.setImageSizeDisplayed(true);
    		panel.setMirrored(true);
    
    		JFrame window = new JFrame("Test webcam panel");
    		window.add(panel);
    		window.setResizable(true);
    		window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		window.pack();
    		window.setVisible(true);
    
    
    
    		final JButton button = new JButton("拍照");
    		window.add(panel, BorderLayout.CENTER);
    		window.add(button, BorderLayout.SOUTH);
    		window.setResizable(true);
    		window.pack();
    		window.setVisible(true);
    		button.addActionListener(new ActionListener() {
    			public void actionPerformed(ActionEvent e)
    			{
    
    				button.setEnabled(false);  //设置按钮不可点击
    
    
    				//实现拍照保存-------start
    				String fileName = "D://" + System.currentTimeMillis();       //保存路径即图片名称（不用加后缀）
    				WebcamUtils.capture(webcam, fileName, ImageUtils.FORMAT_PNG);
    				SwingUtilities.invokeLater(new Runnable() {
    
    					@Override
    					public void run()
    					{
    						JOptionPane.showMessageDialog(null, "拍照成功");
    						button.setEnabled(true);    //设置按钮可点击
    
    						return;
    					}
    				});
    				//实现拍照保存-------end
    
    			}
    		});
    	}
    
    
    
    
    }

--------------------

在以下环境中测试通过： java 1.8 Windows10 64位【其他应该也没问题】
