Review: LG Optimus 3D - Real Time 2D - 3D Conversion!

The first time I was exposed to 2D – 3D conversion, I was on a 42-inch TV and I was watching The Dark Knight. So I was fairly impressed when I saw Nolan’s movie in 3D, knowing that it was a traditionally shot 2D movie. It was no Avatar, but it was cool nonetheless. I even remember Ashraf Ghori’s reaction when he discovered that you could just 3D something, with the flick of a button. From all the gimmicks in the 3D world, 2D – 3D real-time conversion is probably one of my favourites. It allows me to see in 3D things I’d actually want to. I want to insert an inappropriate joke here, but that’s for a later time.

The trick with 2D – 3D conversion is creating the second layer of image (which one eye perceives differently than the other) where it doesn’t already exist. Conventional 3D has 2 layers. Conversion involves creating an illusion of a layer, because the second layer does not exist. How it works, is by create a sharp contrast on-screen – between a large and small object, through overlapping objects, or through differing levels of brightness or clarity – which then forces the right and left eye to analyze things differently.

In continuing my review of the LG Optimus 3D, one of its features is real-time 2D – 3D conversion. Any video that you play on the phone, even those you take with its cameras can be converted, at the touch of an on-screen button, into 3D. First, let’s discuss regular videos: Any video that you see on the phone, be it something that you shot using the phone’s HD camera or a video downloaded into your phone. Once you start playing it, you have the on-screen option to convert the video into 3D. Converting takes about a millisecond as the screen spurts out the video in 3D within a fraction of selecting the option. Real time conversion, it definitely is. The results are not bad either! Bearing in mind that the video was shot in 2D and that conversion takes place on the fly, the results are comparable to that big TV that I saw conversion in. However, there’s the slight difference, that due to LG’s Parallax Barrier screen, you don’t even need those annoying glasses. So switch to 3D on a whim, switch back when you feel like it. All that, without having to put on or take off a pair of oversized glasses.

The cameras at the back of the phone also offer visual delights. Firstly, they look cool. They’re like little eyes at the back of your phone. Incidentally, I’ve decided to name this phone Leonard.
Look into my bulbous bug eyes..
Leonard’s cameras are capable of full HDMI recording, in 2D and 3D. While in 2D its output sits pretty at 1080p. Switch to 3D means you sacrifice a little bit of the quality (you now record in 780p) but you’re carrying around a little James Cameron in your pocket. Switching between 2D and 3D shooting modes is again done at the flick of an on-screen button, activating the second camera to give you a dual perception on whatever it is you’re shooting. As an experiment, I shot 2 videos, both of the same items on my desk, one in 2D (1080p) and the other in 3D (780p). Then I played the 2D one and converted it to 3D with the on-screen feature. Both videos displayed very good quality, however the video shot in 3D was better at depth perception (obviously) than the one that was converted to 3D, which still wasn’t far behind. The depth perception was not as strong in the converted video, but it was there. Interestingly enough, while watching the 3D video, I was given the option to ‘2D’ it. Upon checking what it was, the screen splits in two and you have 2 video feeds, one from each camera. So it actually shows you the 2 individual perspectives, which if you then flick the option again, becomes one video, with depth.

The video below gives a fairly well-marketed impression of the 3D camera. It's pretty sweet..

This phone is very nice and it is offering 3d video in 720 HD the most highest video quality ever in the 3D phones. i would now be switching from Nokia to LG.
