What does the Fraunhofer-Gesellschaft do? And what role does it play?

The Fraunhofer-Gesellschaft is the largest organization for applied research in Europe. With over 60 institutes across Germany, its creative system and technology-oriented innovations contribute to affirming the economic competitiveness of Germany and the whole of Europe.

What precisely is the role played by the Heinrich Hertz Institute (HHI) as just one of the great number of Fraunhofer Institutes?

Located in Berlin, Fraunhofer HHI is dedicated to dealing with issues of communication technology and is a worldwide leader in the development of mobile and fixed broadband communication networks and multimedia systems.

What is 3D or S3D?

Generally speaking 3D simply means three dimensional – or objects in three dimensional space. But when it comes to (motion) pictures 3D should really be called S3D because S or stereo 3D refers to the spatial representation created by two images. The technique that creates this effect is called “stereoscopy” (or stereoscopic or 3D imaging) which is reproduction of images that create the illusion of spatial depth.

Why do we need 3D glasses?

First of all, 3D glasses make it possible to see the spatial depth of the two images that stereoscopic techniques present to the viewer’s left and right eye. Signals from the two images need to reach the brain simultaneously yet by separate channels which is made possible by filtering in the 3D glasses.

What is color anaglyph?

You’re sure to have come across those 3D glasses where one lens or foil is red and the other blue or green: an anaglyph image is formed by the slightly offset superimposing of two complimentary colored stereoscopic pictures. The 'color' glasses filter the pictures to give the wearer the illusion of three dimensional space.

What’s the difference between shutter and polarization in terms of 3D displays/glasses and how do I recognize it in the shops?

Polarization and shutter techniques are different methods for sending two stereoscopic half-images for each eye separately to the brain. The shutter technique uses the concept of alternate frame sequencing to alternate between the stereoscopic half-images while polarization filters the light from the images differently.

What does autostereoscopy mean in relation to 3D?

The full 3D experience without the use of special viewing glasses! Autostereoscopy has so far been reserved purely for (TV) screens. And Fraunhofer HHI is one of the leading proponents of this technique, especially in terms of content development. The stereoscopic images are converted and displayed simultaneously while a line or aperture grid in front of the display inflects the light from each pixel so that each eye sees the correct image.

What does 2D to 3D conversion mean?

This term refers to the fact that the film material was originally shot in 2D, not directly in 3D. The second image is generated in the post production phase as the camera only records from the perspective of a single eye. Broadly speaking, 2D to 3D conversion is just a computing process.

How come that 3D viewing can cause headaches or feelings of dizziness? And what can be done to prevent them?

When we’re viewing in S3D, our eyes must move in ways they’re not accustomed to. In other words, on the one hand we’re looking at the screen yet on the other at the image which sometimes seems to leap out of the screen. This means that the eyes focus differently to how they focus in the real-world. And there is medical evidence to show that this can lead to pains in the eyes, blurred vision or even headaches.

What is Augmented Reality?

Augmented reality is taken to mean an experience of the real physical world augmented or extended by computer technology. If you’ve seen The Matrix movie you’ll have an idea of what augmented reality can look like. It can also be seen as an extension of our sensory perceptions through, for instance, projection of written characters or graphics onto real objects – thus augmenting reality.

Do I need a Blu-Ray player to view 3D films on TV?

The answer to this question is a simple YES you do! You‘ll even need a 3D Blu-Ray player that uses an extended standard! The resolution of a DVD player isn’t high enough to permit a full 3D experience in your living room. 3D Blu-Ray is the high definition successor to DVD. It offers significantly higher resolution and better picture quality which aids in presenting 3D no matter what technology it’s based on.

Can I receive 3D over DVB-T at home?

Sorry to say, with conventional DVB-T technology you can’t receive 3D. This technology can’t even ensure reception of HD. Only with the introduction of DVB-T2 in the next few years will terrestrial reception of 3D become possible.

How does the Sterescopic Analyzer (STAN) work?

It combines hardware and software solutions to capture and analyze stereo images directly at the set so that the two cameras can be adjusted properly to the scene content and that remaining unwanted distortions can be corrected electronically and in real-time.

What role is played by the stereographer in 3D productions?

During production of 3D movies the stereographer checks the effective implementation of 3D on a monitor. He or she also corrects every possible imprecision so that nothing stands in the way of the perfect illusion of three dimensional space.

HFR 3D? What is that?

HFR is short for High Frame Rate. When you went the movies, so far you saw standardized 24 frames per second (fps). Currently this rate is increasing up to 48 to 60 frames per second.

What is 4K or Ultra HD?

4K or Ultra HD revers generally to the resolution of screens, no matter if cinema or tv. 4K in number means 3840 pixels × 2160 pixels, which adds up to a resolution 4 times as high as HD.
