TI's OMAP-DM5x coprocessors promise 20MP cameraphones, 720p recording and freedom from heartache

by Darren Murph posted Oct 16th 2009 at 9:26AM

Another season, another Texas Instruments coprocessor for us to wonder about. For what feels like ages now, TI has been pumping out silicon that promises to bring high-def recording capabilities to cellphones, but by and large, most everything has been stuck at VGA or below. Oh sure, we've seen our first batch of 12 megapixel cameraphones, but it's not like those things are replacing DSLRs en masse. Bitterness aside, the OMAP-DM525 coprocessor is supposedly capable of bringing 20 megapixel imaging to handsets along with 720p video recording, while the OMAP-DM515 hits the ceiling at 12 megapixels. Of course, the DM525 won't actually be ready for volume production until sometime next year, but here's hoping a sample or two slips out at CES.

Samsung's 'Tap and Take' teaser hints at revolutionary, unicorn-approved Smart Cameras

by Darren Murph posted Aug 3rd 2009 at 12:51AM

Samsung sure has been milking this whole "teaser" thing for all it's worth of late, with the newest mystery coming to us in the form of its fresh 'Tap and Take' campaign. From now until August 12th, users can give the read link a visit in order to ingest clues about the outfit's upcoming line of Smart Cameras. These wildly intelligent shooters will purportedly "transform the way consumers take pictures," and they just might provide each and every American with free health care, solve world hunger and put the mighty Hubble to shame. The whole thing will be revealed in full on August 13th, but for now, why not drop a comment below as to what you think will be so revolutionary about the forthcoming point-and-shoot range?

Acoustic superlens could mask ships from sonar... in theory, anyway

by Darren Murph posted May 31st 2009 at 9:32PM

Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.

USB ultrasound device coming to a Windows Mobile phone near you?

by Laura June posted Apr 21st 2009 at 6:43PM

Two computer science professors at Washington University in St. Louis have produced a USB ultrasound probe which is compatible with Windows Mobile smartphones. The project, funded by Microsoft, has developed and optimized probe that uses less power, and is enhanced for data transfer rates on cellphones. The devices could be especially useful in on-the-go situations -- for ambulances, emergencies, and for use by traveling medical staff. The makers also foresee that the device could positively effect medical practice in the developing world, where equipment and doctors can be scarce, and a small, but cellphone access is ever increasingly prevalent. We don't know when these might be commercially available, but they are hoping to sell them for around $500 -- significantly cheaper than many portable ultrasounds, which can cost almost $30,000.

Update: Check out another image after the break.

Scallop Imaging wide-angle security cams look to the sea for inspiration

by Darren Murph posted Dec 15th 2008 at 7:53AM

We're not too sure what's up with New England-based institutions and inspiration from the depths, but the two seem to have some kind of intrinsic connection. The latest company to prove such a wacky assertion true is Boston's own Scallop Imaging, a Tenebraex subsidiary that has developed a "low-cost" security camera that sees 180 degrees of view without fisheye distortion or the lag present in pan-and-tilt alternatives. Additionally, the multi-eyed cam automatically stitches and downsamples images, and can capture a new 7-megapixel still to transmit over Ethernet "every second or two." It's small enough to be placed into a light socket-sized hole, and it's powered by the same Ethernet cable that links it into a building's surveillance system. Of course, the fun won't stop there, as the outfit is already looking at automotive applications of the Digital Window, including "distortion-free backup cameras for the rear ends" of vehicles.

Scientists copy keys with computer imaging to make sure we feel insecure

by Samuel Axon posted Nov 6th 2008 at 7:45AM

Not satisfied with the time-honored traditions of lockpicking or bump keying, computer science professor Stefan Savage and a handful of grad students at the University of California at San Diego have developed a computer system that makes a functional copy of a key based solely on a photograph, regardless of angle or distance -- the image resolution just has to be high enough to make out the details. They claim they did this "to show people that their keys are not inherently secret" so they'll be more careful about flaunting them around in their Flickr photos, but we're worldly enough to know that they really did it to steal beer from rival frat houses. Shame!

MIT conjuring up 6D "super-realistic" image system

by Darren Murph posted Aug 10th 2008 at 5:19PM

2008 has been somewhat of a banner year for 3D, but the brilliant minds at MIT are already working up a system that'll put U23D to shame. Hailed as a "super-realistic image system," the invention produces "6D" images that not only have a full three-dimensional appearance, but also "respond to their environment, producing natural shadows and highlights depending on the direction and intensity of the illumination around them." Without relying on electronics or active control, the process could be used to produce images with an "unprecedented degree of realism" -- resulting in something associate professor Ramesh Raskar calls the "ultimate synthetic display." As expected, initial applications for the ultra-pricey ($30 per pixel, currently) system revolve around digital signage / advertising, but it's really just a matter of time before Six Dimensions of The Jonas Brothers hits a cinema near you. Save us.

Toshiba to showcase "world's smallest HDTV camera" at NAB

by Darren Murph posted Apr 7th 2008 at 7:34PM

Granted, Toshiba Imaging's IK-HD1 3CCD HDTV Camera may not matter much to the consumer as-is, but we're all about the progress. Ready to make its grand, er, wee entrance at NAB Show later this month, the aforementioned unit touts the planet's "smallest" HD camera head (1.6-inches; 2.3-ounces), which should give program producers in tight spots one less reason to not capture content in high-def. In that vein, Tosh even notes that its ability to capture at 1,920 x 1,080 at 30fps makes it "highly suitable for reality TV (you getting this, producers?), specialty broadcast, sports, news and commercials." We know, this totally opens the door for an HD version of Punk'd, but hey, you can't win 'em all.

Nokia N95 + RC plane = unlimited DIY aerial photography

by Darren Murph posted Jun 23rd 2007 at 9:01AM

If you've found yourself tempted by other interesting DIY aerial photography rigs, but spent all your dough on the Nokia N95 instead, you may still be able to make a lifelong (or momentary) dream come true. A pioneering lad over at the N95 Blog has suggested that nearly unlimited high-resolution aerial photography can be yours if you're willing to strap your precious handset to an RC plane and get savvy with Pict'Earth software. The application allows users to create a theoretical Google Earth of their own if the existing imagery isn't up to snuff with their personal standards. Still, we'd have to mull this one over mighty hard before attaching such a valuable communicator to a potential death bed, but feel free to let us know how things go if you can muster the courage.

Your average inkjet can now print Super 8 / 16mm film

by Darren Murph posted Apr 30th 2007 at 7:13AM

No doubt about it, vanilla inkjets seem to be garnering a whole lot of attention these days, and while the latest trick won't yield circuits or OLED displays, it could make filmmakers who long for days past quite excited. Jesse England has apparently discovered a fairly easy to automate process to print video frames onto transparency film. After discovering the dimensions for both Super 8 and 16-millimeter film, he simply made a template, arranged the filmstrip using Adobe's Premier and Photoshop, and printed it out on an everyday Epson inkjet. The noticeably manual task of punching out sprocket holes was still left to a hand-powered box cutter, but we're sure there are less tedious solutions just waiting to be implemented. As expected, the actual video quality was deemed "terrible," but the emotional impact was bittersweet indeed. Be sure to hit the read link for the whole low-down and to see a couple of video demonstrations to show you what the fuss is all about.

NEC's 26-inch MultiSync 2690WXi widescreen monitor gets facetime

by Darren Murph posted Feb 26th 2007 at 10:40PM

Although NEC already went blue earlier today on its new LaVie L laptop, the firm's 26-inch MultiSync 2690WXi widescreen monitor is holding down the ever-trendy white / silver motif. Getting a bit of facetime at Focus on Imaging 2007, the expansive display looks to be a match made in heaven for Mac users who don't feel like springing for any of Apple's own offerings, and is aiming at the eagle-eyed photographer who appreciates color accuracy as much as any specification on a display. The unit purportedly offers up 400 cd/m2 brightness, 178-degree viewing angles, 800:1 contrast ratio, seven-millisecond response time, VGA / DVI inputs, and support for wall mounting as well. It was noted that an elusive "professional" rendition was also on display, alongside quite a few competing EIZO monitors targeting the shooting set, but even the "lower-end" 2690WXi will reportedly demand a stiff £868 ($1,700) for all its color-perfecting ways.

Phoenix's Sky Harbor airport puts omniscient X-ray to use

by Darren Murph posted Feb 26th 2007 at 8:13AM

We don't envision very many people enjoying the idea of having TSA employees seeing every curve their body has to offer, but unfortunately for those who fail the primary metal detector test at Phoenix Sky Harbor International Airport, you could be in for such a treat. While airport shoe scanners have already garnered sufficient criticism for holding up the show rather than helping things out, the "backscatter" X-ray machine is officially being trialed in Arizona as a means of snuffing out hidden "explosives and other weapons" that can't be detected by other means. While the technology allows the viewer to see just about every follicle on your body (and any stray .500 Magnums adorning your person), there is still currently a workaround if you're not entirely comfortable with going full-frontal before boarding your flight. A TSA spokesperson proclaimed that the process is completely voluntary, as folks who get dinged by the metal detector can opt for a standard pat-down in order to clear things up. Interestingly, the officials operating the machine have reportedly "adjusted the equipment to make the image look something like a line drawing" rather than detailing all your 2,000 parts, but critics suggest that altering the image also hampers the chance of discovering contraband in the first place. Still, unless this causes some serious uproar in the near future, it looks like it's there to stay, and folks traveling through LAX and New York's Kennedy Airport will likely face a similar beast (if they so choose) before the year's end.

Colorado researchers edging closer to tabletop X-rays

by Darren Murph posted Feb 26th 2007 at 1:51AM

Although improvements on the typical X-ray are being made quite frequently of late, a team of researchers at the University of Colorado at Boulder is hoping to make a huge leap forward in the way we're forced to handle these traditionally burdensome machines. In an effort to reduce the size required to install and utilize your average X-ray machine, the crew has purportedly developed a new technique to "generate laser-like X-ray beams" that avoid the existing need for such a "monstrous power source." The end goal is, of course, a tabletop device that can handle uber-high resolution imaging at a fraction of the cost and size of current units. It all starts by using "a powerful laser to pluck an electron from an atom of argon and then slam it back into the same atom," which then bypasses the typical problem of X-ray waves "not marching in step" by sending "weak pulses of visible laser light into the gas in the opposite direction of the laser beam generating the X-rays." The feeble beam reportedly "manipulates the electrons plucked from the argon atoms" in order to perfectly intensify the strength of the process by "over a hundred times." Essentially, the researchers have devised a more controlled way to perfect the timing of X-ray blasts, and are utilizing light to focus the process rather than using gobs of energy as it hopes enough undirected beams strike the intended area. Per usual, we've no idea just how close this idea is to becoming ready for the commercial world, but considering all the competition that's currently out there, we don't envision these Buffs wasting any precious time.

Sony's 1/1.8-inch high-speed CMOS sensor outputs 60fps

by Darren Murph posted Feb 19th 2007 at 1:24PM

Thankfully, it looks like Sony has come through yet again, and while it wasn't exactly in the timeliest of manners, the high-speed CMOS sensor that it promised would deliver 60fps of video output is finally upon us. The 1/1.8-inch IMX017CQE sensor boasts 6.4-megapixels of resolution and the uncanny ability to "output this resolution at 60 frames per second (a data rate of around 384 megapixels per second)." In layman's terms, this chip has the ability to capture full motion video and grab high-quality stills without dropping a single frame, giving users a seamless transition between the two. Additionally, the 1/1.8-inch size and its ability to deliver 300 frames per second at lower resolutions moves it a bit further from the pack, not to mention the 12-bit A/D converter for each column. No word just yet on when these video-centric chips will hit Sony's CyberShot lineup, but it's an awful lot closer to reality than the last time we caught wind of it. [Warning: PDF read link]

Mini-Z T-ray imaging device takes home the gold

by Darren Murph posted Feb 17th 2007 at 6:05AM

We're all about giving golf claps where they're due, and a healthy round is certainly in order for Mr. Brian Schulkin. The doctoral student in physics developed a breakthrough terahertz imaging device, dubbed a T-ray, that has already demonstrated its ability to "detect cracks in space shuttle foam, image tumors in breast tissue, and spot counterfeit watermarks on paper currency." The Mini-Z marks the first time such a powerful device has become portable in nature, weighing just five pounds and taking up about as much space as your average laptop. Taking home the first Lemelson-Rensselaer Student Prize ($30,000), Schulkin explained that this device didn't pose the same health risks as typical X-rays, and unlike ultrasound, terahertz waves can provide images and spectroscopic information without contacting an object. As expected, the patent-pending technology is already up for licensing, and has already received quite a bit of fanfare and commercial interest from larger companies. So while you may never personally encounter Brian's earth-shattering invention, we're fairly sure this young lad's working days are already drawing nigh if he so chooses.
