Laser autofocus on your smartphone LG rearranged from a vacuum cleaner

Presented to the market on Tuesday, the Korean flagship LG G3, as expected, distinguished itself by a number of interesting characteristics, but the most striking innovation is laser autofocus. The idea is that at the time of launching the camera, the built-in laser scans the space with a conical beam in the infrared range invisible to the human eye, calculating the distance to the subject. It looks something like this:



or so:

Adjusted for the fact that the naked eye is not really see. By the way, I would look at how the G3 autofocus looks in the infrared.

The LG G3 uses a low-power class 1 laser. The emitter divides the beam into fragments, creating several points of focus. The low power of the laser makes it safe for people, but useless at long distances. The advantage of the laser is manifested in conditions of poor lighting and / or close proximity of the subject.

It is curious that LG developed this technology not at all for the mobile division, but for its Hom-Bot robot vacuum cleaners. True, it never reached the vacuum cleaners, but the LG mobile unit engineers picked up, shook it and built it into what they now call the fastest mobile camera to date, using a laser that provides AF guidance in 0.276 seconds, writes The Verge .



At the same time, laser autofocus works in combination with traditional autofocus and other programs like face recognition, which insure and complement it, for example, at large distances.

Another edition draws attention to the superlaconic camera interface:



- which I would write in the minus - the controls should always be at hand (oh, these designers). But the engineers worked as it should.

I wonder why the vacuum cleaner didn't get the laser?
