Today, Apple was granted 42 patents by the US Patent and Trademark Office. The patents cover various new technologies, including facial detection. The new patent application shows how Apple could use a new method to detect human faces.

The technology could be the precursor of a face-based bio-recognition system that could debut on the upcoming iPhone 8, according to Apple Insider. The patent application is titled “Enhanced face detection using depth information” and describes computer vision technology to recognize objects and human faces.

Face detection algorithms will be capable of scanning a digital image and analyzing it for detecting human faces. The technology could be applied to dynamic scenes like live videos that involve moving objects and users.

The new method could be incorporated in upcoming iPhones

The patent also describes the method using depth information in existing face detection algorithms in order to avoid false detection and cut down on processing overhead. Moreover, the method would involve a specialized infrared light emission system to project a pattern of optical radiation onto a scene. The light could be captured, processed and converted into a corresponding depth map.

The mapping system would be based on PrimeSense’s infrared motion tracking technology, similar to the one found on Microsoft’s original Xbox Kinect sensor. Apple acquired PrimeSense in 2013, so it would make sense for the company to seek to expand the motion capture technology.

It’s unknown whether Apple seeks to develop and integrate the method into upcoming iPhones, but recent rumors have pointed to the company’s desire to tap into such a technology.

A KGI analyst has recently said that Apple will include a revolutionary front-facing 3D camera system on the upcoming iPhone 8, the phone that will mark the 10-year anniversary since the first iPhone was announced. The technology would be used for biometric authentication, as well as gaming. The 3D sensor would be able to detect the location and depth of objects using a dedicated infrared transmitter and receiver.
