Time-of-Flight (TOF) has started popping up more and more lately. It feels like a bit of a buzzword, but it’s actually pretty cool tech. Essentially, it sends out some kind of light (typically a laser) into the environment and then times how long it takes for it to bounce off those objects, creating a pretty accurate 3D map of its surroundings.
It can then use this data for various functions. In the case of phones, that means things like the fake bokeh everybody seems to love these days, but also for faster and more accurate autofocus. And according to a report on MacRumors, it’s coming to two 2020 iPhone models.
