At CES 2014, semiconductor giant Qualcomm gave the media and conference visitors some live demonstrations of the recently announced Snapdragon 805 processor. The company’s new flagship System-on-a-Chip (SoC) is powered by a quad-core Krait 450 CPU (2.5 GHz), an Adreno 420 GPU (500 MHz), and even contains a dual camera image signal processor.
To show what is possible with this higher degree of computational power, Qualcomm showed off some new camera features which may make it into the next generation of mobile devices. Continue reading
The Consumer Electronics Show takes place every January in Las Vegas, and provides us with a glimpse into the newest technologies and gadgets.
At the ongoing CES 2014, GeekBeat.tv did a video interview with Chris Pickett of Pelican Imaging, who explained how their miniature light field array camera module works, and how the company managed to further miniaturize the technology to just half the depth of today’s smartphone camera modules.
In the video, we get to see software refocus (with either a single focus plane or two distinct focal planes and unfocus between) and within-image distance/depth measurements, all done with a modified Android tablet and today’s mobile processors. Light-field video recording and 3D model creation is teased as well. Continue reading
For the past year, the Fraunhofer Digital Cinema Alliance has been researching new, cheaper technology and workflow solutions for 3D film making. In a recent press release, the Fraunhofer Institute for Integrated Circuits (IIS) announced some of the newest innovations from the Spatial-AV project. There’s a new, miniaturized 360-degree ultra-high definition panoramic video camera rig, a prototype microphone management solution for spatial audio recording, and – most interesting to us – a “Light-field Media Production System” that is touted as being “the most innovative lightfield camera recording system to date”.
Let’s have a closer look at Fraunhofer’s setup:
Not too long ago, Pelican Imaging announced their own solution to bring light field technology to mobile devices. In the Lytro Light Field Camera and similar setups, the optical elements take up too much space for integration in smartphones (or other small devices). Pelican chose a different path, using an array of 16 tiny cameras and creating a camera module that is only 3 mm thick (i.e. 50 % of today’s high-end smartphone camera modules), costs 20 $ in production, and creates pictures at 8 Megapixel effective resolution.
At this week’s Qualcomm Uplinq conference in San Diego CA, Pelican showed off their camera and software features on an Android tablet. Continue reading
Today’s light field processing algorithms have mostly been tailored for relatively low image resolutions in the range of a few megapixels. That means, even with increasing sensor resolutions, light field technology will still be effectively limited by resolution. The analysis of light fields at high spatio-angular resolution, so-called “gigaray light fields“, remains a technological challenge due to the sheer computing power it requires.
Researchers at Disney Research in Zürich, Switzerland, have come up with a new, faster way of processing such light fields. Their secret: ignore some of today’s established practices in image-based reconstruction, and try something different.
