尝试一下，

 try {

        Source source = SourceManager.instance().getDefaultSource();
        // Acquire image from default source
        source.open();

        Image image = source.acquireImage(); // Acquire the image

        // Loads the image completely ...
        // Click here to find how to load images completely with MediaTracker.
        // ...

        int imageWidth = image.getWidth(this);
        int imageHeight = image.getHeight(this);

        BufferedImage bufferedImage = new BufferedImage(imageWidth, imageHeight, BufferedImage.TYPE_INT_RGB);

        Graphics2D g2 = bufferedImage.createGraphics();
        g2.drawImage(image, 0, 0, this);

        // Now, you can use the bufferedImage object ...

    }catch(Exception e) {
        e.printStackTrace();
    }finally{
        SourceManager.closeSourceManager();
    }
