The patent is a continuation of a few different patents that date back to 2012, so it’s clear that Apple has been thinking about this type of technology for a while. While the technology looks to be something that could be built into a Mac , it looks even more suited for iPhone.
Depth maps could prove helpful in a number of situations. Not only could they make for more immersive images on a phone, but they could also help in capturing virtual reality content, as well as immersive gaming. Along with the scanner and transmitter, the technology also uses a processor that helps generate the depth map using the information received.
Apple isn’t the only company working on depth maps. Qualcomm has a Spectra camera module that can capture a massive 10,000 points of depth and was included on the new Snapdragon 845 processor. Facebook is also working with Red to build a super high-end 360-degree camera that will support things like depth-sensing and six degrees of freedom. There are also rumors that Apple plans to launch new augmented reality devices, or at least include more augmented reality tech in future iterations of the iPhone, so the ability to sense depth could prove very valuable to the company.
Of course, it’s also possible that Apple won’t end up using the new tech at all. Large tech companies like Apple routinely file for patents that they ultimately don’t use, and it’s possible that this particular depth-sensing technology could fall into that category. Apple, however, has already been experimenting with depth-sensing tech in Face ID on the iPhone X, and it is expected that this experimentation will continue.
