New APIs in iOS 7 Allow Developers to Detect Blinking and Smiling in Photos
According to 9to5Mac, iOS 7 beta 2, which debuted yesterday, added a new function that allows developers to access image detectors to locate facial expressions within photos.
While face recognition was originally introduced with iOS 5, the new APIs can detect distinct expressions like smiles and blinking, functionality that is found in several basic point-and-shoot cameras.
Since the iPhone's debut, Apple has worked hard to improve both the camera hardware and software of its devices, so it is no surprise that iOS 7 will offer multiple camera enhancements for developers. Each iteration of iOS has included new features, such as the volume shutter controls that debuted with iOS 5 and the panorama capabilities added with iOS 6.
Apple's camera expansion efforts have largely paid off, with the iPhone 4, 4S, and 5 ranked as the three most popular cameras on photo sharing site Flickr. The iPhone's camera was also the highlight of a recent Apple advertising campaign.
Along with software improvements in iOS 7, Apple's next generation iPhone is also expected to feature several photo-focused enhancements. The iPhone 5S is rumored to have a higher megapixel camera and a dual LED flash that was revealed in device photos earlier this week.
