Patent Shows That Nokia is Working on Graphene-Based Camera Sensors

Photos and details of Nokia’s upcoming Lumia 920 smartphone leaked earlier this week, revealing that the new flagship Windows phone will feature a 8-megapixel sensor, a 4.5-inch display, 32GB of storage, and wireless charging via a special pad.

Although the camera specs seem rather pedestrian compared to the 41MP 808 PureView, patents published last month reveal that the company is working on some special sensor tech for future devices. More specifically, Nokia is working on developing camera sensors that use layers of graphene — one-atom-thick layers of carbon — for big performance advantages over existing sensors.

How Hyperspectral Cameras Are Being Used to Uncover Ancient Mysteries

Hyperspectral cameras are those that can capture information in the electromagnetic spectrum, far beyond what the human eye — and consumer cameras — can see. American Photo Magazine has a fascinating feature that tells of how researchers around the world are using the cameras to uncover century and millennium-old mysteries:

The historic discoveries are just getting started. No one yet knows how much researchers and scholars will find with this new generation of hyperspectral technology. More than a hundred years ago, in the ancient Egyptian city of Oxyrhynchus, archeologists found piles of illegible papyrus. Recently, University of Oxford researchers found that they contained fragments of a lost tragedy by the ancient author Sophocles, of whose plays only seven were known to have survived. New imaging methods have also found portions of a poem by Archilochus that reveal new details about the genesis of the Trojan War. The research at St. Catherine’s could settle long-standing debates over the origins and foundation of some of the world’s major religions.

Discoveries using hyperspectral photography so far include revisions to the US Declaration of Independence, hidden words in the Dead Sea Scrolls, and a possible Abraham Lincoln fingerprint on a copy of the Gettysburg Address.

P.S. Last year, a group of scientists was able to create a hyperspectral camera using an ordinary Canon 5D and random off-the-shelf parts.

Apple Moves One Step Closer Toward Location-Based Camera Disabling

In June of last year, we reported on an unsettling patent filed by Apple that would allow certain infrared signals to remotely disable the camera on iPhones. It showed the potential downsides of bringing cameras into the world of wireless connectivity, which appears to be the next big thing in the camera industry. Now, a newly published patent is rekindling the fears of those who don’t want “Big Brother” controlling their devices.

The Light Show on CN Tower is Actually a Subliminal Photo Slideshow

If you’ve visited the CN Tower in Toronto, Canada anytime during the past five years at night, you’ve likely enjoyed the dazzling light show that appears on the side of the tower. The 1,330 uber-bright LED lights (which cost a cool $2.5 million) were installed in the elevator shafts back in 2007, and are turned on from dusk every day until 2 the next morning. What you might not have known, however, is that the seemingly random colors that appear are really not so random after all: they’re actually pieces of photographs!

Scientists Create a Distortion-Free Lens That’s Essentially 2D

Think pancake lenses are flat? In the future, camera manufacturers might be able to replace those bulky glass elements inside lenses with lens elements that are thinner than a piece of paper. The lenses would not only be third-dimension-free, they would also be distortion-free.

Photos of the Future May Be Stored on Strands of DNA

If you think modern day hard drives store a lot of data, get a load of this: researchers at Harvard have succeeded in storing roughly 700 terabytes of data in a single gram of DNA. The strands of DNA are treated much like other storage devices, except instead of using electric charge or magnetism to store information, DNA’s four bases (A,C,G,T) are used.

Future Cameras May Have Lithium-Ion Batteries That Recharge in Minutes

What if the battery in your camera could be charged in the same amount of time it takes to microwave a cup of instant noodles? It sounds crazy, but that’s what appears to be headed our way.

Researchers at the Ulsan National Institute of Science and Technology in South Korea have figured out a way to drastically cut down the time it takes to recharge a lithium-ion battery — the same kind found in most digital cameras.

Great Scott! Corneal Imaging is Actually a Real Thing!

Earlier today, we poked fun at a clip from the TV show CSI showing some pseudo-scientific photo enhancing. Many of the comments on YouTube also poked fun at the mention of “corneal imaging”, in which the investigators used to obtain imagery from the reflections seen in an eyeball. Turns out corneal imaging is a real thing…

Magical App Uses Your Phone’s Camera to Accurately Measure Your Pulse

“Any sufficiently advanced technology is indistinguishable from magic.” That’s the quote by science fiction author Arthur C. Clarke that you’ll find on Cardiio‘s homepage. It’s a quote that is quite appropriate, given what the app can do.

The app is a touch-free heart rate monitor that can accurately tell you your pulse by simply looking at your face through your phone’s camera.

Color Photo Printed at 100,000 DPI, the Highest Resolution Ever Achieved

Stuff a few thousand dots per inch into a color print, and you have yourself a pretty high resolution image that most people would approve of. What if you could stuff 100,000 dots into that same inch?

That’s what researchers were able to do recently in creating the highest-resolution photograph ever printed — and one of the smallest, to boot.
