The rear-facing 8-MP camera in the iPhone 4S is one of the best in the smartphone world. How can Apple make it better? Rumormongers recently suggested the iPhone 5 could get a 3-D camera, a bit of gossip that appears to have sprouted from a March 29 story by Patently Apple, which reported that Apple had developed a "killer" 3-D imaging camera for still images and video. The article didn't say the camera would be included in the next-gen iPhone, however.
What makes the 3-D camera cool? Improved sensors for better depth-detection and color accuracy, as well as the ability to recognize facial gestures. It sounds like a work in progress, though, and probably won't appear in a shipping product until the iPhone 6 at the earliest.
