According to Patently Apple (via the Daily Mail and Pitchfork), Apple is developing software for precisely that.
The software would recognize when the iPhone’s camera was in use. Infra-red sensors installed at the venue would activate the software and disable the camera. Other functions would continue to work normally. The Daily Mail speculates that Apple may be trying to placate broadcasters who have purchased exclusive rights to events. This would also serve as a way to curb posting of copyright material online by users who do not hold the rights.
Could Apple charge users to record such events? If so, Apple will have figured out a way to monetize amateur filming in venues. Patently Apple also reports that the photo function would be able to be disabled this way too.
What do you think? Should Apple be able to decide whether you can record an event with your phone?
