earlier today lg introduced its 2014 flagship: the g3. based totally on qualcomm's snapdragon 801, the g3 features a five.5" 2560 x 1440 show and a host of different upgrades over final year's g2. although the front and rear going through cameras don't change in phrases of decision in comparison to the g2, the imaging system did see a few enhancements. optical photograph stabilization (ois) is back for the g3, but it now includes stabilizing alongside the z-axis as nicely (hence ois+). the massive new feature but is the ir laser rangefinder that aids in improving cognizance time for the rear digicam. lg claims the g3 can grab awareness in 276ms. it is clear that the g3's af machine is one of the maximum thrilling that i have visible in smartphone imaging, full forestall. even as pdaf (phase detect car awareness) is widespread on dslrs, laser rangefinders are usually uncommon and from any other technology.
even as a few guessed that this gadget became a method of helping with automobile recognition with the aid of projecting a grid of lasers that would assist with detecting maximum evaluation, lg uses correct timing of emission vs mirrored image to determine the distance to a target. searching at the ir window with an ir touchy digital camera, the beam emitted is extremely thin in perspective, an awful lot more targeted than the average laser pointer. which means that the chance of multiple returns is substantially reduced as compared to most situations.
lg emphasised the hybrid nature of its gadget, and is the reason how the g3 compensates for conditions in which the laser automobile cognizance fails. it appears that lg compensates for a couple of returns, transparent and reflective surfaces with comparison-primarily based af detection as needed. lg also stated that the best gain to the laser gadget is for almost immediate detection of distance to difficulty for the primary two feet, and in cases wherein contrast detection is used the laser machine lets in the af algorithm to automatically pass this distance to hurry up focus. lg additionally says that the best gain is seen in low mild. i believe that during outside situations the sign to noise ratio drops considerably. all of those claims will need verification, lg has in reality made a totally thrilling device for his or her camera, an interesting change off between the bigger sensor length and pdaf of the gs5 and the ois+ and laser af of the g3.
it's now not quite clean how the laser af is implemented in the software program even though. primarily based upon some casual inspection there is no clear reference to a laser or ir out of doors of television. it's miles probably that the entire implementation is achieved thru a unmarried digital camera driving force which obscures just how the rangefinder is dealt with. at any rate, all of this may require similarly research in a full evaluate.
