Nvidia Near-Eye Light Field Display: Background, Design and History [Video]

Nvidia Near-Eye Light Field Display: Binocular OLED-based prototype (Youtube Screenshot) About a year ago, Nvidia presented a novel head-mounted display that is based on light field technology and offers both depth and refocus capability to the human eye. Their so-called Near-Eye Light Field Display was more a proof of concept, but it’s exciting new technology that solves a number of existing problems with stereoscopic virtual reality glasses.

Nvidia researcher Douglas Lanman recently gave a talk at Augmented World Expo (AWE2014), in which he explained the background and evolution of head-mounted displays and the history and design of Nvidia’s near-eye light field display prototypes: Continue reading

Pelican Imaging: CEO explains the Power of Light Field Imaging [Video]

Pelican Imaging has recently released a short video where CEO Chris Pickett explains what’s so interesting about light field photography:

In the 2-minute clip, Pickett explains how Pelican’s Array Camera works, and shows its most exciting features: software refocus, multiple focus (focus on several depths in one image), segmentation (automatic depth-based object extraction). Continue reading

Light Field Smartphone: Pelican showcases Full-HD 3D Video

Pelican Imaging is working hard on releasing “a smart camera for your Smartphone”. Their first generation 4×4 camera array is reportedly 50 % thinner than current smartphone camera modules. It captures the Light Field not by use of a microlens array, but using – in this case – 16 individual fixed focus cameras.

But hardware is only one part of the technology. It’s strengh lies in the power of post-processing and sophisticated computation.
In a new demo released today, Pelican Imaging demonstrates 3D video recording at 1080p and 30 fps, as well as two application examples: distance measurement within the picture, and 3D printing of recorded scenes. Continue reading

DIY Next Generation: Custom 3D-printed 49 mm Lytro Filter Adapter

DIY Next Generation: Custom 3D-printed 49 mm Lytro Filter Adapter (photo: Perry-Myworld) We’ve seen quite a few filter adapters for the Lytro LightField Camera before, but Perry’s solution takes the “Do it Yourself” spirit one step further:
Perry used a high resolution 3D printer (Objet24, 28 µm layer thickness) to print a custom filter holder for his Lytro camera:

My goal here is to create a filter holder for my 49mm filters. After printing today and testing, it holds my +2 and +4 close-up filters very well. No slippage, no hint that anything would fall off. (The macro filters provide little benefit except being able to close focus and the Lytro’s longest focal length, down to 5 1/2″ at 51.4mm.)

More pictures after the break: Continue reading
