Fraunhofer's STAN: four cameras, three dimensions, no glasses
There are some glasses-free 3D TVs around, but their limited viewing angles and poor picture quality aren't very inspiring -- so Fraunhofer's latest project is a welcome endeavor. It's developed STAN (STereoscopic ANalyzer), a system that lets broadcasters easily use four cameras instead of the usual two, for 3D recording. 3D needs a minimum of two lenses to register depth and keeping multiple shooters in sync is tough and expensive. That's led to the industry relying on two, which is why glasses-free (autostereoscopic) 3D TVs get such a poor picture; more cameras means more viewing angles. STAN co-ordinates the setup of the four cameras and then uses a feature detector to identify common elements in the pictures and merges them into a 3D image. Four cameras provide much more depth, which means more viewing angles, which means that if STAN gets picked up, these guys can throw away the sunglasses, even for live broadcasts.
Hitachi announces high-res 4.5-inch IPS display for smartphones with improved glasses-free 3D
There's still no word as to when it might actually land in some phones, but it looks like glasses-free 3D could soon see some improvements courtesy of Hitachi's latest 4.5-inch IPS display. Not only does it boast a high 1280 x 720 resolution, but it uses a less common lenticular lens approach instead of the parallax barrier method used by the likes of the Nintendo 3DS and HTC EVO 3D. According to Hitachi, that allows for much brighter 3D images than other displays (470 cd/m2, specifically), and images that are actually brighter in 3D mode than in 2D mode. Here's hoping Hitachi shows off a bit more than the image above before too long.
Gadmei P83 PMP does glasses-free 3D for $179
A no-name PMP selling for $179 at Brando -- purveyor of all things inexpensive, electronic and often USB-powered -- may not ordinarily make the grade for us, but this so-called Gadmei P83 device has one somewhat notable trick up its sleeve. It packs an 8-inch, 1,280 x 768 display that's able to do glasses-free 3D video. Of course, you're left to yourself to actually hunt down or provide your own compatible video files, and the PMP itself is decidedly ordinary otherwise: 4GB of storage, an SD card slot for expansion, and the usual media playback capabilities and nothing more (no one's going to confuse this for a tablet). Still curious? Head on past the break for a video that offers a slightly more accurate depiction of the device than the image above.
Toshiba Regza GL1 3D preview: no frills, no glasses, some issues (video)
It's with some surprise that we pen, finger to key to screen, praise for a 3D display -- particularly one that is glasses-free (the staff is still a bit divided, for example, on Nintendo's 3DS screen). But here we go. Toshiba's 20-inch Regza 20GL1 3D set was on hand at CEATEC, and it's actually a set we could see ourselves comfortably watching for a given span of time. Viewing angles are none too shabby, the refresh rate doesn't visibly distract or inherently cause headaches, and at 720p, you can actually get an enjoyable image. The 56-inch concept conjured up a worthy picture as well, but then again, it's a prototype with no immediate purpose other than causing attendee awe at this point. If we had to fault it, we'd say that the viewing angles where you see two distinct perspectives (see the picture above for an example) are too wide, which means you'd have to be really careful about where you sit on the couch if you were to buy something like this for your den. Also on hand was a notebook, which at this point just didn't cut it. Perhaps it's just too early in development, but what was saw had minimal depth and an unfortunately low resolution / perceived refresh rate; when the video loop it was playing switched to the Windows 7 UI, it looked grainy and extremely difficult to read -- undoubtedly the side effect of trying to use a display designed for permanent 3D use in 2D mode. That leaves us to talk about 12-inch 12GL1, and what can we express other than disappointment? The 466 x 350 resolution (yes, that's less than standard definition) is just awful, you can lose the 3D effect moving marginally to the left or right, depth is not pronounced, and medium-to-fast pace footage just doesn't work. For all the warm-yet-cautious approval we give to the 20GL1, its little brother is quite the black sheep, especially at ¥120,000 ($1,443). Not that ¥240,000 for 20 inches is a bargain, but at least you're getting a quality screen... and for once, you don't actually need additional eyewear to enjoy it. Decidedly two-dimensional snapshots and video taken from an almost pitch-black showroom (i.e. very not optimal) can be found below. %Gallery-104266%
Sharp's 10.6-inch parallax barrier display makes us love our 3D glasses (video)
Now that the Nintendo 3DS is announced using a parallax barrier display, we bet that many of you were hoping to see a 10-inch 3D tablet or laptop with a similar glasses-less display. Hell, we were... until we actually saw Sharp's prototype 10.6-inch parallax barrier display here at IFA in Berlin. Unfortunately, the panel at this larger size suffers from some very serious vertical shadows (check the video) unless you're right in the sweet spot and aligned with the barrier's precision slits at a distance of about 20 inches. Even then, it's very hard to maintain your position, and the 3D effect isn't all that dazzling. Fortunately, this 3D (640 x 768) panel also functions in 2D (1280 x 728) mode. Guess a 3D tablet that requires glasses isn't so crazy after all. Wait, yes it is.
