Toshiba preps 20MP, backside-lit sensor for point-and-shoot cameras

Toshiba preps 20megapixel, backsidelit CMOS sensor for pointandshoot cameras

When smartphones are encroaching on compact cameras' turf, how does a company try to stay relevant making sensors for those cameras? By upping the resolution, of course. Toshiba has given a peek at the TCM5115CL, a 1/2.3-inch, backside-illuminated CMOS sensor that hits 20 megapixels -- a big jump from the 16-megapixel sensors in many point-and-shoots and some smartphones. To combat the noise and sensitivity problems that usually come with a denser design, the electronics giant is using pixels that can absorb 15 percent more of a charge, and therefore more light. Toshiba has primed the sensor for high-speed shooting and video as well, with the potential for 1080p video at 60FPS and 30FPS burst shooting at full resolution, provided the processor can keep up. We're not bracing ourselves for an imminent renaissance among dedicated cameras, however. Mass production doesn't start until August, which suggests we're unlikely to have 20-megapixel shooters in our pockets during summer vacation.

Toshiba preps 13MP phone camera sensor that promises low-light shooting without the noise

Toshiba preps 13MP phone camera sensor that promises lowlight shooting without the noise

Toshiba isn't the most vocal of mobile camera designers; it's often shouted out by the likes of OmniVision and Sony. It has reason to crow now that it's near launching a next-generation imager of its own. The 13-megapixel, CMOS-based TK437 sensor carries the backside illumination we already know and love for its low-light performance as well as color noise reduction that should fight the side-effects of such a dense, sensitive design. If we take Toshiba at its word, the visual quality of the sensor's 1.12-micron pixels is equal to that of much larger, less noise-prone 1.4-micron examples -- important when stuffing the sensor into 0.33 square inches. Photos will prove whether the achievement is more than just talk, although we'll have some time to wait when test samples will only reach companies in December. It's months beyond that before there's a production phone or tablet with a TK437 lurking inside.

OmniVision unveils 5MP BSI sensor that takes low light cameras further into the entry level

Posted on by

OmniVision unveils 5MP sensor that takes low light photography to the entry level It's almost a truism that starter smartphones have poor cameras that struggle just to get pristine photos in broad daylight, let alone dim interiors. Thankfully, OmniVision's new OV5645 sensor could lead newcomers out of a very literal darkness. The 5-megapixel imager includes backside illumination, support for 1080p30 (or 720p60) video and its own internal autofocus system, but no dedicated JPEG compression engine -- in short, a lot of the low-light performance of more sophisticated smartphones without the usual attached costs. Its cost-cutting even extends to front cameras, as a forward-facing sensor can share resources with the back camera to scale back on redundant hardware. We're looking forward to when mass production starts in the first quarter of 2013; we might not have to excuse our photo quality for a long, long time afterwards.

HTC 8X Review Windows Phone 8's compact flagship

More Info

It feels like forever since Microsoft announced Windows Phone 8 back in June, but the mobile OS is finally here and with it comes the inaugural volley of compatible handsets. The first one to cross our desks is the global, unlocked version of HTC's Windows Phone 8X, a device we first saw in September. Unlike other current flagships, this phone breaks the bigger-is-better trend by providing a full set of high-end specs in a relatively compact package -- combining a 4.3-inch 720p Super LCD 2 display, Qualcomm dual-core Snapdragon S4 processor and NFC in a sleek and colorful package. Does the 8X have what it takes to carry the Windows Phone 8 torch? Is this a bona fide flagship despite its reduced footprint? Has HTC designed a better handset than its existing Android superphone, the One X? Find out in our review after the break.

LG Optimus G review: a quad-core powerhouse with Nexus aspirations

LG Optimus G review a quadcore powerhouse with Nexus aspirations

More Info

You've heard it before: the more things change the more they stay the same. It wasn't that long ago that we reviewed LG's flagship Optimus 4X HD, the world's first quad-core HSPA+ handset. Despite representing the company's best engineering and design effort to date, it wasn't quite able to match the competition's global offerings -- Samsung's mighty Galaxy S III and HTC's lovely One X. Today, just a few months later, quad-core LTE superphones are the state of the art. Samsung's selling the global Galaxy Note II, HTC's just announced the One X+ and LG's betting everything on the Optimus G -- the first handset to feature Qualcomm's Snapdragon S4 Pro together with an LTE radio.

The Optimus G is a pivotal device for the Korean manufacturer, especially in the US, where rival Samsung is massively popular and LG's success has been hampered by a series of forgettable products (hello, Intuition) and a lackluster track record for software updates. It's so critical that LG even invited us to spend some quality time with the Optimus G at the launch event in Seoul last month. In the US, LG's partnering with Sprint and AT&T and there's strong evidence that Google's upcoming Nexus will be based on the Optimus G. So, does the company's latest powerhouse measure up to the competition? How different are the US versions from the Korean model? Does LG finally have a winning formula with the Optimus G? Find out in our review after the break.

Pentax intros X-5 superzoom camera with 26x lens, tiltable LCD

Pentax intros X5 superzoom camera with 26x lens, tiltable LCD

We'd been worrying that Pentax would be left out of the flurry of new cameras in the run-up to Photokina. With the new X-5, there's reason to relax. The new shooter sits at the higher end of the by-the-numbers superzoom crowd, centering most of its energy on a 26x, 22-580mm equivalent lens as well as a backside-illuminated CMOS sensor that should keep the resulting 16-megapixel photos and 1080p videos relatively clean. Most of the effort to stand out from the pack, however slightly, involves previewing pictures rather than capturing them -- an electronic viewfinder and a tilting, 3-inch LCD will help perfect those macros and overhead concert shots. The X-5 won't shake the foundations of personal photography, especially not when it's using AA batteries for power, but hitting all those right notes at a $280 price could persuade more than a few of us to take the plunge after the September launch.

Olympus Stylus TG-625 Tough adds AF light for tricky shots in rough situations

Olympus Stylus TG625 Tough adds AF light for tricky shots in rugged scenes

It's been awhile since we've seen Olympus tackle the more affordable side of its rugged camera lineup, which makes its latest entry feel overdue. The Stylus TG-625 Tough effectively replaces the TG-620 by adding something that's been commonplace in the camera world: an autofocus illuminator light to improve focusing at night or, more likely with this camera, when it's plunged 16 feet underwater. Outside of a new double-lock system, though, you're looking at the hardware that has defined most of Olympus' rugged line this year, including a 12-megapixel backside-illuminated CMOS sensor, a 28-140mm equivalent lens, 1080p movie making and a 3-inch LCD. The Japanese should get the TG-625 the soonest, on August 31st. There's no word on whether or not there's an upgrade on the way for the US, although we can picture it slotting into the American lineup without much trouble.

LG Optimus 4X HD review: runner-up to the quad-core throne

DNP LG Optimus 4X HD review runnerup to the quadcore throne

More Info

LG has an ongoing smartphone problem: despite a few valiant efforts (the G2x comes to mind) the company continues to live in the shadow of rival Samsung. Most of this malaise can be attributed to hit-and-miss hardware combined with lackluster software (we're looking at you, Spectrum). Last February, at Mobile World Congress, LG spiced things up with an attractive collection of devices including the Optimus L7, Optimus Vu and Optimus 4X HD -- the latter being one of the first quad-core handsets announced. Now, six months later, we live in a world where the global versions of HTC's One X and Samsung's Galaxy S III dominate the superphone market and share the quad-core crown. With me-too features like a Tegra 3 processor, 4.7-inch HD display, 8-megapixel camera and Ice Cream Sandwich on board, the Optimus 4X HD appears ready to play in the big leagues. Does it succeed or is it just a flash in the pan? Is it all style over substance or does it bring something unique and meaningful to the table? Hit the break for our full review.

OmniVision’s 12.7-megapixel OV12830 can shoot 24 fps photo bursts from your smartphone

Posted on by

ImageOmniVision has been on a bit of a tear introducing new mobile camera sensors this week, and its newest could well have the biggest impact on smartphones in the next year. The OV12830's 12.7 megapixels don't make it as dense as the 16-megapixel sensors we've seen, but it makes up for that with some mighty fast still photography. As long as the attached phone can handle it, the CMOS sensor can snap full-resolution photos at 24 frames per second, or the kind of relentless shooting speed that would make One X and Galaxy S III fans happy. The same briskness musters 1080p video at 60 fps, even with stabilization thrown in. Production won't start until the fall and likely rules out a flood of 12.7-megapixel phones and tablets until 2013, but the OV12830's dead-on match for the size of current 8-megapixel sensors gives it a good shot at becoming ubiquitous -- and guarantees that phones won't need a giant hump on the back for a higher resolution.
