Interesting to note: iPhone and iPad and a lot of Android devices don't have a camera indicator LED. While it is difficult to distribute iOS Apps outside the AppStore (where Apple would hopefully reject an App accessing camera information without informing the user) this totally could happen with Android Apps distributed outside of App Stores. A while ago I wrote a component for the iPad that emulates the proximity sensor of the iPhone by measuring the brightness of images the the front camera captured. There was no way for the user to detect that I was actually capturing images.
