Don't know how much you know about digital camera's so I hope I don't offend, but have you tried switching the camera to "Macro Mode". This focus' the camera for shorter distances and you should get even better results.
This is of course assuming that the camera has a macro function, and that you aren't already using it.
Hope this helps
