title: Could anyone guide me to develop with qrcode in blackberry?
body: <p>I am developing my camera application that can decoded the qrcode in real time of camera on. </p>
  
  <p>When I open the camera,  I set the timer about every 3 seconds interval to capture picture on the screen with Display.screenshot(); method and then decoded it with zxing library while camera is on.   Sometimes, it can capture the qrcode and successful decoded, but otherwise it hard to decoded the picture.  I think the problem is about camera. I can not use auto focus with the camera, so the capture picture is gloomy.  I want to know how to use auto focus with the camera.</p>

  </ul>
  
  <p>Could anyone help me or suggestion about new solution ?</p>
  
  <p>Thank you so much</p>
