title: Capture Image using Python and Open Cv 2.3
body: <p>I am using Linux Mint 12, Kernel 3. I have installed and configured Open CV 2.3.
  I can capture images and videos using my camera "through gucview. 
  I can capture videos using cheese "but problems happen with photos".
  I can read images using Open CV, but I can't capture images from Web cam.
  When I capture an image, I get an empty window.
  When I check if the image is captured or not, I get True as a result. I am using "Python Bindings"
  Any help with that!</p>
