By now it’s highly likely that the camera in your smartphone has become the primary (or even only) way that you take pictures. Today’s advanced smartphone camera setups are capable of much more than snapping scenery or selfies, though. Did you know they can reveal the location of hidden spy cameras?
This new ability is thanks to the addition of a time-of-flight (ToF) sensor to many new models. The sensor helps a smartphone analyze depth information about a scene that’s being photographed.
