I set the focus on my camera to "macro". Macro shots are extremely close shots. This way I can take clean pictures of the screen. I don't know what happens when you take pics with a camera phone, but mine has the option as far as I can remember. You seem to take pictures of your TV though. A good camera with auto focus ought to do the trick.
If you're using an emulator, you should be able to stretch the window and make it bigger without losing quality. Which emulator are you using?
