    "Once we’ve got the 3D pose of each photo, we compute the depth of each pixel in the reference photo using Multi-View Stereo algorithms. MVS works the way human stereo vision does: given the location of the same object in two different images, we can triangulate the 3D position of the object and compute the distance to it. How do we figure out which pixel in one image corresponds to a pixel in another image? MVS measures how similar they are -- on mobile devices, one particularly simple and efficient way is computing the Sum of Absolute Differences (SAD) of the RGB colors of the two ...

    Michael published the review of the HTC One M8 last Tuesday. In his time with it, he snapped dozens – maybe even hundreds – of photos, not only because that's protocol when reviewing a phone, but for two important, additional reasons: the Duo Camera is a primary feature of the M8, and its camera, especially the resolution, has been a controversial topic since the phone was made official. I've voiced my opinion about it. I wasn't impressed, based on what Michael and many other first-round reviewers had posted. The camera seemed gimmicky, the images it produces are often noisy and lack ...

    I'm tired of telling you what to think about the HTC One M8 camera. Actually, telling you how to feel isn't what a review is supposed to do; ideally, it provides information you need to make an informed decision about whether or not to buy a particular product. But that information needs to be placed in the proper context, and that always involves injecting some opinion –sometimes a great deal of it– into a piece. Finding a balance between the subjective and the objective is the tough part. Nowhere is that tougher than when discussing a smartphone's camera performance. We're not a ...

    With other smartphone technology advancements beginning to plateau, such as display quality (resolution, color, black levels, etc.) and CPU capabilities, OEMs are looking to other areas for differentiation. Alongside things like software features and packing massive batteries, one area several manufacturers have started focusing efforts is image sensing, as indicated by the massive achievements in both 2012 and 2013. First was Nokia's PureView technology with the not-so-mainstream, Symbian-powered 808 PureView, which came packed with a 41-megapixel sensor capable of taking up to ...

    Taking photos is one of Apple's main selling points for its iPhone line-up. We can't deny that ever since the launch of Apple's old iPhone 4, this has garnered a certain level of positive fame for Cupertino. It's only logical that Apple will search for additional usage scenarios for the iPhone's camera because of this, and new patents point to some ideas that may come. Apple has just patented an iPhone camera remote, which is straight forward in its functionality. It connects though Wi-Fi or Bluetooth to an iPhone or iPod Touch and allows you to control all the camera features remotely in ...

    Many of us were expecting MWC 2014 to be full of the innovations that we didn't get. Smartphones with 2K displays, and significant camera improvements were just some of the things we predicted, and no company delivered. By contrast, the only company that has teased these features on an upcoming handset is Oppo with its Find 7, and a new rumor has just made this device even more attractive. A leaked image taken by this phone according to the EXIF data claims that the resulting photo is of 8160x6120 resolution. If you do the math, this would require a 50 megapixel sensor in order to ...

    Update: 24 hours have passed, and the answer lies below! Scroll carefully if you haven't yet seen this month's game submission and you want to preserve your chance for an unspoiled guess! When it comes to analyzing the quality of a smartphone's camera, there are two main approaches. There's the guided style: "We had a gander at the new [Smartphone] from the fine folks at [Smartphone Manufacturer], and we took its camera out for a spin to see how it performed under a variety of lighting conditions. When it comes right down to it, this camera is [excellent][great][good][not so ...

    Update: T-Mobile has responded to our request for clarification. The press material accompanying this device was incorrect; there is no OIS on this unit. The camera movement we saw is a result of the camera's autofocus system. Pocketnow regrets the error. When we first laid eyes on the Sony Xperia Z1S last month at CES 2014, we weren't exactly blown away. Not because there was anything wrong with the device -its specs were great and its glossy glass construction was just as fetching as it had been on the Xperia Z1 we'd reviewed some months before- but because there wasn't much to set it ...

    Just as we saw earlier that Apple was granted a patent for a smarter stylus, it seems that Cupertino is hard at work at nailing additional patents. The iPhone has always been famous for the good image quality of its camera, but it seems that Apple wants to take things a step further. The company was just granted two patents for interchangeable lenses on the iPhone. One of these patents deals with the lens' ability to enhance image quality through better optics, and the other patent deals with the lens' ability to attach to the iPhone magnetically. These patents aren't new though. Apple ...

    Rumors of the purported successor to the HTC One, the M8, are only heating up and growing in number. They're becoming marginally more revealing and helpful. Still, we're missing a few pieces of important information. If you've ever tried to put together a giant puzzle without all the pieces, you know at some point, the only thing left to do is to fill the gaps and holes with your imagination. And when it comes to technology, the imagination is in constant danger of distorting the facts and adding extra digits where they don't belong. Some of the most recent tidbits of information on the M8 ...

    The year is quickly coming to a close, and looking back, it's safe to say this has been the year of smartphone cameras. HTC, Samsung, Nokia, Motorola, LG, Sony, and several others have tried their hand at innovating the next breakthrough in camera technology, creating the perfect balance of mobility, pocketability, and image quality. Some, obviously, did better than others. HTC, for one, proved that while the image sensor on the One wasn't the best in the industry, it's meager 4-megapixel sensor packed a serious punch. LG managed to create one of the most balanced mobile cameras to date ...

    The Nexus 5 has seen its share of coverage this week - not just at Pocketnow, but all across the internet. It's not just the newest major Android smartphone to see release; it's the once-a-year Nexus phone straight from Google. As such, it commands a degree of exclusive excitement, a hipsteresque appeal that merits a whole lot of media coverage - despite bolder devices hitting the market elsewhere. Much of the excitement for the Nexus 5 comes from owners of the current-generation Nexus 4, last winter's Googlephone Of The Moment that warranted almost the same level of feverish fanboyism. ...

    As we spent the morning anticipating on the latest episode of the Pocketnow Weekly podcast, Google's long-awaited Nexus 5 finally got itself announced today. It was a long slog; even earlier today, as the minutes turned to hours and all those "confirmations" started dissolving into the nothingness from whence they came, it was looking like yet another false alarm. But just as we were starting to retool for a November 1 release date, the Nexus 5 hit the Google Play Store. And when units finally start arriving at buyer doorsteps over the next few days, they'll come packing a feature that I ...

    After comparing the Sony Xperia Z1 with two of the leading Android smartphones, the Samsung Galaxy S 4 and the HTC One, we decided not to neglect the Windows Phone fans out there. Whether they want to switch to the Xperia Z1 from the Lumia 925, or some of you want to decide between getting one of these two devices, this is for your, and not only, viewing pleasure. The conclusion is the hardest thing to draw: if you’re a fain of Android, or Windows Phone, there’s little chance anybody can convince you on the contrary. However, if you’re looking for your first phone, you have to first ...

    Windows Phone is home to some of the best mobile image sensing innovations of late. And while the app situation is improving, there are still many holes in the content selection. Photo editing apps, sadly, is one of those holes. That doesn't meant there aren't any photo editors. There are. And some of them are pretty nice, but they still fall short of the selections on other platforms, such as Android or iOS. Snapseed and Adobe Photoshop Touch for Phones aren't available on Windows Phone, for example. But there are some decent alternatives. Watch this video to learn about the best Windows ...

    There are few things in this world more gratifying to me than snapping a beautiful photo with a smartphone. I don't consider myself a photographer, I just like to take pictures of various things for fun. The challenge makes it sort of exciting – how I imagine early film camera adopters felt when snapping photos of the most mundane things and developing the film to see how the shots turned out. And proving naysayers (read: pro photogs) wrong in that smartphones can take amazing pictures is an especially sweet bonus. As such, for the last two years, camera quality has been a key factor in ...

    If you thought the Palm commercials of 2009 were as weird as mobile tech advertising would ever get, HTC and Robert Downey Jr. have something to show you. That's the conversation that kicks off this week's edition of the Pocketnow Weekly podcast, and it's followed by some heartening news about this year's IFA in Berlin. If the rumors hold true, we should be in for some powerfully geeky, if unconventional, tech in Germany this year - and even if they don't, we've got plenty to talk about in the way of chipsets, Nexii, smartwatches, and phablets. If none of those terms make sense to you, ...

    Reviewing the world's biggest and baddest smartphones is an awesome job, but it can also be a stressful one. Often, the time between review and release is very short, requiring long hours and a little compromise when trying to deliver timely impressions. So it's always a pleasure when, after the initial review but before the Empty Nest and After The Buzz phases, you get to settle in with a review device as your temporary daily driver. It's during this time that the device's personality solidifies, its assets and shortcomings becoming more defined. And, in the case of a smartphone like the ...

    (Updated 7/29/2013 with additional battery endurance information. See "Performance," below.) The A-10 Thunderbolt II is a ground-attack aircraft operated by the U.S. military. It's big, it's slow, and it's built around a single dominant feature: the 30mm cannon slung under its cockpit. The A-10 is also so ugly that it's one of the few planes in the world known better for its nickname than its official designation: pilots long ago rechristened the ugly bird the "Warthog," and the name stuck. It's anyone's guess what nickname the mass market will give to Nokia's latest Windows Phone ...

    Which is better: physical lens doing optical zoom, or the PureView technology? We want to find out in our Samsung Galaxy S4 Zoom vs Nokia 808 PureView camera comparison below. We've got two fundamentally different approaches to imaging here. While the Samsung Galaxy S4 Zoom employs lens and physical zoom for getting closer to your subjects, the Nokia 808 PureView (and the Nokia Lumia 1020), are using a huge 41-megapixel sensor which gives you the power to crop towards the center of the image, hence selecting a portion of the entire canvas, for zoom. We'll be updating this post shortly ...

    Yesterday, Nokia finally made one of the most leaked, rumored, and talked about phones official – the Lumia 1020. Ever since the 808 PureView was announced in February last year and it was discovered the Lumia 920 would come with an entirely different type of PureView camera, optical image stabilization instead of lossless digital zoom, Windows Phone fans have been dying for more PureView love. It's not that the low-light performance of the 920 wasn't great or that the phone was disappointing, but a phone with lossless digital zoom and a 41-megapixel sensor is in an entirely different ...

    So, remember last year when the Lumia 920 was announced, and I declared I'd buy it to use as my personal smartphone? That was pretty cool, and so was the experience of actually following through with it. The 920 has served as trusty sidekick ever since, earning high marks in durability, in vacation photography, and in overall After The Buzz performance. It's been a pretty excellent smartphone, one I'm proud to carry. But ... there's always been a "but." The 920's camera, awesome as it is, is branded "PureView." That's the same branding that Nokia used to launch its 808, the Symbian-powered ...

    It's not every day you schedule a podcast the day before one of the biggest Windows Phone announcements in the platform's history - but given our plans to host a special-edition Pocketnow Live event covering Nokia's NYC event tomorrow, we thought it best to get the Weekly out of the way ahead of time. That doesn't mean we don't talk Nokia - indeed, we've got Chief News Editor Stephen Schenck on the air with us this week to discuss what it's been like to follow the story of the EOS/1020/909, probably one of the most widely-leaked devices in smartphone history. We also follow the leaky ...

    As you've probably heard, we've got some Nokia news to look forward to this week. If the rumors and leaks are to be believed, the company is gearing up to drop quite a smartphone on the world come Thursday - and whether it's called the EOS, 909, 1020, or something else, it's a safe bet its name won't be the big story. Taking center stage will most likely be its super-sized camera module, which at an assumed 41MP seems guaranteed to blow the pants off every other device out there not called an 808 PureView - including Nokia's current Windows Phone flagship, the Lumia 920. But the Lumia 920 ...
