Canon EOS 7D gets high marks all around

by Vladislav Savov posted Nov 7th 2009 at 4:52PM

Canon's EOS 7D is a pretty grandiose piece of image-recording equipment, whether you're talking about its size, features or price. You're probably aware of the 18 megapixel APS-C sensor and dual DIGIC 4 processors already, but we've all had to be a bit more patient than usual in waiting for the pro reviews to come out. Dpreview doesn't disappoint though, with a thoughtful 31-page tome awaiting the keen reader, and we've also got more digestible video reviews from DPhoto Journal for the less patient among you. If you're after direct comparisons against competing models, such as the Nikon D300s, you'll find those sprinkled in among the reviews as well, with Cameratown throwing in a direct head-to-head with Canon's own 5D Mark II. The 7D was found to produce "virtually no visible noise" all the way up to ISO 1600, and scored further points for its gorgeous 100 percent frame-covering viewfinder and fast 19-point AF. With a weather-sealed, highly ergonomic body design, ridiculously fast processing and a sensor so good that "in most situations the lens, rather than the camera, is likely to be the limiting factor," the only thing reviewers could criticize was the somewhat uncompetitive pricing, but that's likely to soften with time anyway. Read on... if you dare.

Albatron's 42 inches of optical touch monitor get examined on video

by Vladislav Savov posted Oct 28th 2009 at 12:23PM

While Dell and HP were busy holding a competition to see who could do a worse job of announcing their new optical multitouch displays, Albatron was crafting away a 42-inch monstrosity to completely steal their thunder. The optical part refers to a pair of CMOS sensors embedded in the bezel which are responsible for touch detection, a cheaper alternative to your typical capacitive and resistive tech, which requires an extra USB connection between the monitor and computer. Although some issues were found with Windows 7's multitouch implementation, the promise of recognizing more than two fingers with the proper software support and the general responsiveness of the unit whet our appetite for more. Alas, nobody dares speak of a price, but a 1080p 22-inch model is already available for $450, in case you wanted to add to your touchy-feely shortlist. The video after the break contains the hands-on and a little mystery -- why is there Bulgarian handwriting on the whiteboard in the background?

Toshiba launches 14.6 megapixel CMOS sensor with backside illumination for cellphones

by Tim Stevens posted Oct 27th 2009 at 9:34AM

Backside illumination may sound like something a proctologist would use in a poorly-lit examining room, but it's actually a re-imagining of the CMOS sensor that brings the photodiodes closer to the action, thus delivering brighter images from smaller packaging. OmniVision and Sony both have their takes on the tech and now Toshiba is putting it into a 14.6 megapixel sensor for cellphones and compact cameras. The company claims light absorption is boosted by 40%, resulting in bright pictures despite the high-density 1/2.3-inch sensor. Early production will begin before the end of the year but manufacturing lines won't start firing en masse until sometime next summer, meaning yet another dark and murky winter of dark and murky pictures.

Hitachi builds 3mm-thick vein scanner in its Transylvanian lair

by Vladislav Savov posted Aug 28th 2009 at 8:19AM

Hitachi has always been hot for vein authentication modules, and its latest iteration takes the whole tech down to just three millimeters in thickness. Given that the current generation requires 23.5mm (nearly an inch) of space to operate in, it's easy to see why your netbook doesn't have one, but Hitachi hopes that's all about to change. Using a CMOS sensor to take almost instant readings, the vein scanner is deadly accurate -- there's only a one in a million chance of it authorizing the wrong person. Volume production is expected within two years, meaning that by 2011 you'll finally have a reliable way to keep your parents out of your "Misc" data folders.

Natal Xbox 360 in 2010 rumor is back on

by Thomas Ricker posted Jul 22nd 2009 at 8:39AM

Although Microsoft's marketing department likes to keep its execs on a short leash, you really should listen to its CEOs when they espouse launch schedules. They are, after all, CEOs and tend to have the big picture (like dates) related to major projects that drive revenue. Recall 2008, when Bill Gates told the world that Windows 7 would arrive in 2009 causing Microsoft marketing to scramble-out a redaction attempting to reset expectations for a 2010 launch. With Windows 7 now officially launching in October, well, guess who was right? Fast forward to last month when Steve Ballmer made a similar slip saying Project Natal would arrive in 2010 causing Microsoft to issue a statement that a launch date had not been confirmed. Now DigiTimes is reporting that Aptina has won the exclusive rights to equip Natal with a 1.3 megapixel CMOS image sensor required for Natal's camera. More importantly, the Taiwanese rumor rag says that shipments of the "new version of the Xbox 360 console" are slated for the second half of 2010 -- a date that sounds like Fall to us as previous rumored. Of course, DigiTimes was absolutely certain that Microsoft was integrating Blu-ray into future (that'd be 2008) Xbox 360 consoles too, so take this rumor for what it is: rumor.

Interactive data eyeglasses could bring the PC to your face, won't fix nearsightedness

by Darren Murph posted Jun 4th 2009 at 8:19AM

Leave it the mad scientists at Fraunhofer-Gesellschaft to concoct this one. Rather than just figuring out a way to read back information in one-way fashion on one's glasses (think Sixth Sense, but with eyewear), these folks are diving right in to the real stuff: bidirectional communication. In essence, their goal for the interactive data eyeglasses is to track eye movement in order to allow ones retinas to scroll through menus, flip through options and zoom in / out on a map. Obviously, a microdisplay will be necessary as well, but that's just half the battle. We'll confess -- we're still not humble enough to take our Vuzix HMD out in public, but we just might swap our Transitions™ for a set of these.

eASIC eDV9200 H.264 codec promises HD for all devices

by Darren Murph posted May 12th 2009 at 9:16AM

We've already got HD in places that the cast of Step by Step would've sworn was never possible way back when, but eASIC is far from satisfied. To that end, it's introducing a new H.264 codec aimed to bring high-def capabilities to all manners of devices, including (but certainly not limited to) toys, baby monitors, public transportation, wireless video surveillance and wireless webcams. The highly integrated eDV9200 is said to "dramatically lower the cost of entry into the high-definition video market, enabling a new class of low-cost applications to fully leverage the benefits offered by HD technology." Best of all, these guys aren't just blowing smoke, as the chip -- which captures streaming data directly from a CMOS sensor, compresses it, and transfers it to a host system or to a variety of storage devices -- is priced at just $4.99 each in volume. HD oven timers, here we come!

Nikon readies entry-level DSLR with articulating display for April 14th launch? (updated with spyshots!)

by Thomas Ricker posted Apr 6th 2009 at 12:26PM

Word on the prismatic, hinged mirror streets of camera-land suggest that NIkon is preparing to launch "new products" for Spring. Rightful speculation made after a press invite was purportedly sent to a variety of photog publications announcing an April 14th launch event. Expectations vary widely as to what will be announced including a new entry-level D60-followup with 720p video on up to a D400 with 16 megapixel Sony CMOS. We even have the dubious photo above showing a Nikon with articulating display taken by a jockey riding a humor forum who claims to have been traveling "somewhere in Eastern Europe and stumbled across a commercial shoot for Nikon." Sure, that's believable. Fortunately, we're just over a week away from knowing for sure.

Update: Well, well, what's this... we just received a big batch of spy shots that look authentic enough and clearly show what looks like a low-end Nikon with articulating display.

Update 2: We just received a few more pictures as well as the detailed backstory to this Nikon with swiveling display (a first for Nikon). Seems Kevin, a film student, was smitten by the Arriflex ~~235~~ 435 motion picture camera used to film the commercial in Dubrovnik, Croatia yesterday. It wasn't until later, when he was reviewing the pics from the day, that he realized "that the subject of the commercial was the yet to be announced Nikon 500(0?)." Looks like a legit and incredibly fortunate find to us.

[Thanks, Kevin]

Canon working on DSLR-based pro video camera?

by Nilay Patel posted Mar 30th 2009 at 1:23PM

It's a pretty sketchy rumor, but we're hearing that Canon's working on a pro video camera based on a 12.1 megapixel APS-C CMOS sensor similar to the one in the Rebel XSi. That makes perfect sense to us, actually -- DSLRs with video capabilities like the 5D Mark II and the new Rebel T1i have definitely shaken up people's expectations of prosumer video, and Canon's sitting on a well-regarded camcorder division primed to pounce on a new market. According to CanonRumors, the new pro cam will look similar to the XL H1 pictured above with support for EF and EF-S lenses, sport fully manual controls as well as autofocus, and shoot 720p/30/60 and 1080p/24/30/60 to 56Mbit/s MPEG-4. Sounds pretty good, but aye, there's a rub: word is that Canon's DSLRs won't ever get similar video features in order to protect this cam's high-end $8,000 price tag -- which sucks, but also makes perfect (if annoying) sense to us. It's all rumor for now, but we'll see how it pans out -- the pro and prosumer video market are about to get crazy interesting.

Ricoh's CX1 camera gets reviewed

by Joseph L. Flatley posted Mar 24th 2009 at 11:41AM

The kids at Photography Blog have finally got their hands on that Ricoh CX1 that won our respect not too long ago, and they've been cool enough to post a review online. The camera, the reviewer said, begins where the ol' R10 left off, throwing features like multi-pattern auto white balance, multi-target auto focus, and 4fps continuous shooting speed into the mix, making this "the best Ricoh point-and-shoot yet." That said, it can't all be groovy -- the review goes on to cite the camera's "bog-standard" 640 x 480 / 30fps video and rudimentary face detection as "nothing to write home about." Image quality -- often a deal-breaker for this company -- has greatly improved, with a new 9 megapixel CMOS sensor sporting "a now usable ISO range of 80-800." Of course, the big news is the camera's high dynamic range. DR mode is, for the most part, "radical and very effective." But there's much more to it -- hit that read link for all the gory details.

Ricoh's CX1 point and shoot combines two shots for greater dynamic range, glory

Ricoh's CX1 point and shoot combines two for greater dynamic range, glory

While high dynamic range is only recently getting some attention in the gaming and display worlds, for decades it's been a tool of serious photographers wanting eye-popping exposures. Now Ricoh's gone and offered it to the masses with its latest consumer digi cam, the CX1, creating a "dynamic range double shot" mode that takes two images nearly simultaneously with different exposures, then combines them automatically to present the best bits of both. It features a 9 megapixel CMOS sensor fronted by a 7.1x (28-200mm) lens and backed by a 3-inch LCD. VGA videos are a bit disappointing these days, but 120 frames per second can be captured at that resolution, which is good news for slow-mo junkies. UK release is mid-March for £299, about $430, and we expect/hope it'll be lighting up dim photos Stateside around the same time.

Probabilistic logic makes microchip more energy efficient

by Darren Murph posted Feb 9th 2009 at 6:09AM

We'll be straight up with you -- there's a lot of fancy work going on with this one that laypeople will have a tough time grasping, but the long and short of it is this: a team from Rice University (Krishna Palem pictured) and Nanyang Technological University have created a microchip that "uses 30 times less electricity while running seven times faster than today's best technology." Already crying snake oil? Not so fast. By trashing the traditional set of mathematical rules (that'd be Boolean logic) and instead applying probabilistic logic, researchers have figured out how to deliver similar results with a fraction of the energy. The tech is being dubbed PCMOS (probabilistic CMOS), and could eventually end up in embedded systems and even cellphones. In the case of the latter, this type of chip will be able to display streaming video on a minuscule display with more artifacts than usual, but due to the small screen size and the human brain's ability to piece together nearly-perfect images, the errors involved would be all but forgotten. Meanwhile, your battery bar would still be nearly full. We always heard there was beauty in imperfections -- now, at long last, we finally get it.

NEC develops processor for 12 megapixel camera phones

by Ross Miller posted Feb 6th 2009 at 9:22AM

No sooner than we get wind of a possible Samsung 12 megapixel camera phone does NEC reveal a linear shift-invariant (LSI) chip that, along with the proper CMOS sensor, can bestow onto mobile devices the power to shoot 12 megapixel imagery, as well as output full-HD video. Dubbed the CE143, it's being touted by the company for Its focus speed and signal-to-noise reduction 6db greater than with what's currently in the market. The chip will integrate with an image stabilizer, shading correction, and other essential point-and-click tools. Manufacturers should expect to get some hands-on time when samples begin shipping out in March. Keep a lookout for this one at Mobile World Congress later this month.

Sony announces new CMOS sensors, 12+ megapixel cameraphones coming soon

by Tim Stevens posted Nov 13th 2008 at 8:51AM

If you've enjoyed the point-and-shoot megapixel race, which has pushed sensor resolutions in your average 3X zoom compact cam well into the teens -- leaving a sad trail of dark and noisy holiday pictures in its wake -- you're going to just love the mobile phone megapixel race. Samsung's 10 megapixel SCH-B600 currently holds the lead, but Sony's got a ringer chomping at the bit with the Exmor IMX060PQ CMOS sensor, which, paired with its matching auto-focus lens module, will turn some lucky handset into a 12.25 megapixel shooter when it enters the race in March. Sony has also announced 5.15 and 8.11 megapixel sensors, but really, anything not in double digits is so last year.

Megapixel race hits the mobile realm

by Darren Murph posted Sep 28th 2008 at 8:27AM

When the megapixel race unofficially started in the point-and-shoot world, it didn't take long before every last camera manufacturer out there was cramming 14-megapixel sensors into any ole pocket cam. Now, it seems the same race is headed to the mobile realm. Of late, we've seen a new batch of 8-megapixel handsets and a 9-megapixel sensor, and a recent interview with LG's sales and marketing director John Barton points to even more of those in the near future. According to him, "the megapixel race that we saw amongst camera makers is now being battled out between mobile manufacturers," hinting that 10+ megapixel phones (not to mention handsets with HD video capability) are closer than we may have imagined. Mmm, the possibilities.
