The way 3D technology is developing is certainly worth a mention.
3D Fusion Corp recently declared they have succeeded in making a path breaking invention in the world of 3D technology. They will put up a demonstration with respect to this invention and will be broadcasted this week at the National Association of Broadcasters’ trade show in Las Vegas, Nevada.
Most of the heavy weights and the brainstorming masterminds from the electronics industries consider this event as one foreseeing the technologies about five to ten years in the future. This will be seen this week and will also be analyzed by the Media representatives and N.A.B attendees.
The 3ALITY Digital pavilion, located outside the Central Hall, will witness a demonstration based on a live3D TV video feed from the 3ALITY Digital 3D camera arrays. The footage will of course be based on a live Basketball play on the basketball court constructed just outside the Central Hall at NAB. Now what do you derive from this?
With the advent of 3D TVs and various models many viewers have complained of discomfort while watching 3D content for a long time with their glasses on. Hence the technology of having to watch the 3D content without the use of glasses may be considered as the HoThis will be a live feed given to a 3D TV directly and this will also mark the usage 3D Fusion technology to watch the footage without the aid of 3D glasses.ly Grail in referral to the 3D technology. This also comes with the broadcast quality quite similar to the one on 2D broadcasts. Now how would you complete a 3D technology upgrade? You would need everything starting with all the primary performance requirements ranging from control room engineering to live camera capture and most importantly viewer display.
The following is a comparison made by Steve the President of 3D Fusion between watching 3DFMax 3D TV without your 3D glasses on and with them.
“Though we are targeting the richness of the With Glasses 3D imaging, our 3DFMax images are designed to mimic the way the eye sees. It is a more ‘real’ natural 3D image which can be enjoyed as effortlessly as conventional television without any eyestrain, viewing restrictions or unacceptable side effects. With the 3DFMax 3D TV technology, the viewer can adjust the 3D depth impact to his personal preference, on the fly in real time. He has the same control as he would in correcting color or adjusting volume with his remote control.” “Now for the first time ever,” continued Blumenthal, “a live 3D TV, glasses free, ASD and 3D camera capture system, is presented to the NAB community.”
With the advent of 3D glasses with polarizing filters and LCD shutters you’d be forgiven for thinking we’d seen the last of the archetypal numbers with different colored filters.
Well, think again because European researchers have come up with technology they say can display 3D images at a monitor’s full resolution, with no darkening of the ambient light, no restrictions on viewing angle and with less strain on the eyes than other 3D technologies – and yes, it relies on glasses with different colored filters.
There’s no secret that current 3D technologies aren’t perfect. After the initial hoopla surrounding the latest batch of 3D entertainment, best illustrated by Avatar, people have started to notice a few pitfalls. The glasses – both passive (polarized) and active shutter – cause a noticeable dimming of the image. Also, anyone who has shelled out for a new 3D TV will likely have noticed that it has to be watched with the head in an upright position. Simply tilting your head can cause ghosting and color changes, while laying down can cause the image to disappear altogether. As has also been widely reported, some people can suffer headaches and nausea when watching 3D for an extended period. Not exactly what you’d expect from the next big thing in home entertainment.
German and Swiss researchers on a EUREKA project say they have developed technology that overcomes these problems. The breakthrough is the result of three friends at German company Infitec wanting to develop a 3D LCD flat-screen monitor capable of displaying the full resolution of the new high-definition television formats.
Everything old is new again
Infitec had already developed 3D technology for cinemas called wavelength multiplexing, which is based on the principle of the old red and green glasses. The company’s glasses use a much narrower color band wave than the traditional red and green glasses to improve the quality of the image, using specific wavelengths of red, green and blue for the right eye and different wavelengths of the same colors for the left eye. Filtering out very specific wavelengths provides different images to the left and right eyes, giving the spectator the illusion of 3D.
Infitec then partnered up with Swiss company Optics Balzers, which specializes in 3D filters and the two companies secured funding to start developing the 3D LCD screen. While Infitec researched the best signal and lighting to use in the monitor and software for it, Optics Balzers developed special filters for the lighting unit and the glasses.
It’s not uncommon to see children attempt to reach out and touch objects the first time they don 3D glasses and sit down in front of a 3D TV.
Researchers at the University of California, San Diego, have created a new virtual reality device that enables users to do just that. The relatively low-cost device called the Heads-Up Virtual Reality device (HUVR) combines a consumer 3D HDTV panel and a touch-feedback (haptic) device to enable users not only to see a 3D image, but “feel” it too.
The system consists of a 3D HDTV panel placed above a half-silvered mirror that reflects the image from the panel back to the user. The user’s head position is tracked to generate the correct perspective view while they maneuver a touch-feedback device underneath the mirror, through which the user’s hand is still visible. This provides the illusion that the user is literally ‘touching’ the object being displayed.
Its creators say HUVR is ideal for tasks that require hand-eye coordination and is well-suited to training and education in structural and mechanical engineering, archaeology and medicine. The device could be used to visualize and manipulate a 3D image of a person’s brain taken from an MRI, or an artifact too fragile or precious to be physically handled, for example.
“By using HUVR’s touch-feedback device – which is similar to a commercial game control – a physician could actually feel a defect in the brain, rather than merely see it,” explained Research Scientist Tom DeFanti, who is affiliated with the UC San Diego division of the California Institute for Telecommunications and Information Technology (Calit2), and created the device with Calit2’s Virtual Reality Design Engineer Greg Dawe. “And this can be done over the networks, sharing the look and feel of the object with other researchers and students,” Defanti added.
With the TV heavyweights unleashing a torrent of 3D LCD and plasma TVs upon us this year it would be easy to assume that those are the only technologies capable of providing 3D viewing in the home. A small Los Gatos, California-based startup called HDI is out blow such assumptions out of the water with what it says is a superior 3D alternative. By all reports the company’s laser-driven 100-inch 2D/3D Switchable Dynamic Video Projection Television delivers a stunning 3D picture, thanks in part to its boasting the highest refresh rate of any mass-produced television or projector.
Laser TVs aren’t new, and although they’ve attracted praise for their impressive picture quality and energy efficiency, they haven’t really set the world on fire in the sales department. HDI is hoping to change that with its laser-driven 3D offering. HDI says its display delivers a 2D image with a 50 percent greater resolution than today’s digital cinemas and derives its high definition stereoscopic 1920 x 1080p “3D” image quality from two RGB laser-illuminated Liquid Crystal on Silcon (LCOS) micro display imagers.
At full 1080p HD, the HDI Ltd. screen refreshes at 360 fields per-second on each eye. According to the company this high refresh rate eliminates the adverse effects, such as migraines, dizziness, and nausea, long associated with substandard 3D display technology. For conversion of 2D content to 3D HDI TVs will utilize real time converter technology from HDlogix.
The projection technology that can be found in HDI’s TV’s, as well as it’s projection systems, relies on three low wattage lasers that transmit laser light, (red, green and blue), to a controller via fiber optic cables. This controller combines the different colors to sends a full-color image through prisms that separate the laser lights into two channels – one for each eye. Two LCoS imagers then capture the high definition 3D images and they’re ready for projection.
The two overlapping images are projected at a rate of 360 frames per second for each color for a grand total of 1080 images per second – far greater even than the 480Hz LED 3DTV unveiled by LG last month. In another point of difference to the current crop of 3D TVs being released the HDI offering can be viewed using passive polarized glasses instead of the more expensive active shutter glasses. And an added bonus of using lasers is that energy consumption can be kept down to less than 200 watts for a 100-inch set.
Initially HDI had hoped to license its 3D technology to existing TV manufacturers but no one was interested so HDI decided to start a TV company and produce the sets itself. It will be aiming its 100-inch TV at high-end, custom install users as well as corporate boardrooms, studios and sports bars.
LG has unveiled what is the sure to be the first of many LED TVs to get the 3D treatment.
The LX9500 is illuminated by panels of LEDs directly behind the screen for local dimming, with the 55-inch model alone boasting 1,200 of the semiconductor light sources. The LEDs help the TV achieve a 10,000,000:1 dynamic contrast ratio while sporting an ultra-thin 22.3mm (less than 1 inch) deep body with a stylish 16mm super-narrow bezel.
Other features of the full HD 1080p set include TruMotion 400Hz (480Hz), NetCast support, Wireless AV Link and HDMI 1.4. Video calling using Skype is possible with an optional video camera, and the unit is DLNA ready with an optional DLNA dongle. The LX9500 uses active shutter glasses that can be recharged via USB for up to 40 hours of uninterrupted viewing pleasure – after which you should probably toddle off to bed.
