Frontback is an offbeat app meant to capture images from both of your smartphone’s cameras simultaneously (showing “You, and what you see”). Evidently Canon is now building two sensors into point-and-shoot cameras to enable this sort of “Dual Capture mode.”

Elsewhere the FLIR One camera case promises to give your iPhone Predator-style heat vision:

The company anticipates that homeowners and contractors will use its thermal imaging system to identify energy efficiency problems, like poorly insulated doors or windows, and to find wall studs or ceiling joists.
It also foresees its technology used by hunters, bird watchers, and campers to observe wildlife, to navigate in darkness, to assess whether campfires have really been extinguished, and to determine whether food has been adequately cooked.
And the company claims FLIR One can “detect intruders in total darkness.”
