According to the smart folks over at MIT, this video shows footage that was captured at an unbelievable one trillion frames per second. It appears to show some kind of light pulse traveling through some kind of object. Here’s a confusing explanation found on the project’s website:
We use a pico-second accurate detector (single pixel). Another option is a special camera called a streak camera that behaves like an oscilloscope with corresponding trigger and deflection of beams. A light pulse enters the instrument through a narrow slit along one direction. It is then deflected in the perpendicular direction so that photons that arrive first hit the detector at a different position compared to photons that arrive later. The resulting image forms a “streak” of light. Streak cameras are often used in chemistry or biology to observe milimeter sized objects but rarely for free space imaging.
In the future, after you print photos onto paper using your camera, you’ll be able to scan them and share them on Flickr using your mouse. At CES earlier this year, LG showed off an amazing new mouse that lets you quickly scan images and documents by simply waving the mouse over them. Now it’s available — if you live in the UK, you can buy one from Dabs for £90 (~$150).
As technology improves, features that were once limited to expensive professional models often become available to the masses, but will this ever be true for full-frame sensors? Nikon’s Senior VP David Lee was recently asked this question in an interview with TWICE, and here’s what he said:
I think that there are definitely two different approaches here. What we’re seeing is that sensor performance continues to improve, but obviously there’s really a need for bulk because with a full-size sensor there’s a real low-light performance benefit, high speed performance, framing rates, and so on and so forth. So, I think you’ll definitely continue to see the higher-end pro consumer continue to have that large format. It’s definitely needed in the D3 and D700. You’ll see that technology continue to improve and grow, but the DX sensor form factor is also important. The compactness of the D3100 and D5100 is very popular. I don’t think one approach will ever overtake the other because of the overall image capabilities and the light performance capabilities.
Seems like he either misunderstood the question, or decided to beat around the bush. It’s an interesting question though — will any of the big manufacturers shake up the industry by being the first to put a full-frame sensor in a consumer-level camera? The sensors have already jumped from pro-level cameras to prosumer-level ones starting in 2005 with the Canon 5D, so it seems like the next logical step will be the consumer level. A sub-$1000 full-frame camera. Now that’s a thought.
Last week it came to light to Amazon founder Jeff Bezos had filed a patent for having airbags built into cell phones to protect them if they’re ever accidentally dropped. Rather than having a NASA-style airbag that completely envelops the phone, micro air jets orient the device so that it lands on a tiny airbag that pops out of the bottom. Wouldn’t it be interesting if this kind of thing became common on digital cameras in the future? The idea is pretty farfetched, but some people I know would definitely benefit from camera airbags.
There’s a good chance the digital photos you’ve stored on hard drives and DVDs won’t outlive you, but what if there was a disc that could last forever? M-Disc, short for Millenial Disc, is a new type of disc that doesn’t suffer from natural decay and degradation like existing disc technologies, allowing you to store data safely for somewhere between “1000 years” and “forever”.
Existing disc technologies write data using an organic dye layer that begins to experience “data rot” immediately after it’s written, causing the disc to become unreadable after a certain amount of time. The M-Disc, on the other hand, actually carves your data into “rock-like materials” that are known to last for centuries, meaning there’s no data rot. Apparently NASA uses the discs to store data. Hopefully it becomes available and affordable soon…
For his project “Back from the Future”, photographer Sander Koot asked his subjects to find old photos of themselves that brought back good memories. He then made portraits of those people reliving those happy moments. Read more…
Facial recognition features are appearing in everything from cameras to photo-sharing sites, but have you thought about the different security and privacy concerns it introduces? Fast Company has published a piece on how mobile apps in the future may be able to quickly look up your identity, your personal information, and perhaps even your social security number!
[CMU researchers] used three relatively simple technologies to create their face recognition system: An off-the-shelf face recognizer, cloud computing processing, and personal data available through the public feed at social networking sites such as Facebook [...] Combining the data gathered from the face recognizer hardware with clever search algorithms that were processed on a cloud-computing platform, the team has performed three powerful experiments: They were able to “unmask” people on a popular dating site where it’s common to protect real identities using pseudonyms, and they ID’d students walking in public on campus by grabbing their profile photos from Facebook.
Most impressively the research algorithm tried to predict personal interests and even to deduce the social security number of CMU students based solely on an image of their face–by interrogating deeper into information that’s freely available online.
Having a camera that shoots 5000 frames per second is enough to capture slow motion footage of a bullet flying through the air, but scientists at the Science and Technology Facilities Council have now announced a camera that shoots a staggering 4.5 million frames per second. Rather than bullets, the camera is designed to capture 3D images of individual molecules using powerful x-ray flashes that last one hundred million billionth of a second. The £3 million camera will land in scientists hands in 2015.
Facial recognition technology has become ubiquitous in recent years, being found in everything from the latest compact camera to websites like Facebook. The same may soon be said about location recognition. Through a new project called “Finder“, the US government military research division IARPA is looking into how to quickly and automatically identify where a photograph was taken without any geotag data. The goal is to use only the identifying features found in the background of scenes to determine the location — kinda like facial recognition except for landscapes.
