New image detectors that recognize facial expressions — such as blinking or smiling — have been added to iOS 7 beta 2, according to a report. Facial recognition has been around since iOS 5, but the new APIs could allow developers to add new features based on particular expressions, such as taking a photo when no one in the frame is blinking. Although at this point the feature only appears in the underlying iOS APIs, it’s possible that Apple could include new features in its own Camera app for the official release of iOS 7, as new Camera features are usually instituted with each new OS.
