Apple developing new 3D sensor system for 2019 iPhone rear camera, according to Bloomberg


Bloomberg today reports that Apple is developing a new 3D sensor system for the 2019 iPhone. This sensor would work differently to the TrueDepth sensor system used for Face ID and would be used to add depth sensing features to the rear camera.

Adding depth data to the rear camera would allow for more advanced augmented reality applications. iPhone X and iPhone 8 Plus simulate depth by using a dual-camera system, and comparing the parallax of the images from the two lenses.

Bloomberg says that Apple would use different technology for the rear-camera 3D system than the technology used by the TrueDepth camera system.

The TrueDepth system shines about 30,000 dots outward, which is then captured and analyzed. The distortion of these dots creates the depth map. This is how Face ID gets the data it needs to check for a match and unlock the device. The report says the new sensor for the 2019 iPhone back camera relies on a time-of-flight algorithm, measuring how long it takes for a laser to hit an object and bounce back.

However, the TrueDepth tech would remain for the front camera. The new time-of-flight system would only be added for the back-facing camera, according to the supposed Apple roadmap.
