I'm capturing webcamera Image using following code:
import com.asprise.util.jtwain.Source;
import com.asprise.util.jtwain.SourceManager;

try
{
Source source=SourceManager.instance().getDefaultSource() ;
source.open();
img=source.acquireImage();
 //get the bufferedImage
  BufferedImage bufferedImage = getBufferedImageFromImage(img);
  disp.setIcon(new ImageIcon(bufferedImage));
      }

The intemediate step is provided by asprise.com but it is a licenced one. I want to capture image without going through this. How do I do that?
