Chipworks throws an iPhone 4S under its infrared microscope, finds Sony-sourced image sensor
Look closely. Can you spot it? That gray abyss is actually an infrared image by Chipworks revealing an iPhone 4S' Sony-branded, 8 megapixel CMOS sensor. Looks like Howard Stringer wasn't bluffing to Walt Mossberg back in April, after all. At the time, it was reported that Apple's usual sensor supplier, OmniVision, was experiencing production delays, prompting speculation that Sony would eventually usurp the position. While the iPhone 4S that Chipworks looked into seems to confirm this, it's pointed out that Apple does have a habit of "dual sourcing" components (with its contacts saying this should be no different), so Sony may not be the sole supplier this time around. What ever the case, there's no denying that the iPhone 4S takes some stellar shots. You'll find more information -- including X-rays of the 4S -- at the source link below.
Joe Pollicino10.16.2011Toshiba unveils new CMOS sensor, flaunts smaller pixels
Hoping your next smartphone will have more megapixels while being even thinner than the last? Us too, but we're not known to skimp on image quality -- an unfortunate conundrum of squishing more pixels into a tighter space. Enter Toshiba's new CMOS sensor, advancing on both fronts, with 8 megapixels and what the firm reckons is the smallest pixel size in the industry at 1.12 micrometers. Also present is backside illumination, helping maximize photon accrual -- which should make a certain Steve oh-so proud. Currently being sampled, the teensy gizmo plans to go into mass production later this year. Interested? Peep the full release after the break.
Dante Cesa07.08.2011World's biggest CMOS sensor could help doctors detect and treat cancer
Move over, Canon, because scientists at the University of Lincoln have just seized the crown for world's biggest CMOS image sensor with their new Dynamic range Adjustable for Medical Imaging Technology microchip -- or 'DyNAMITe,' for short. Measuring a hefty 12.8 square cm (or about five square inches), DyNAMITe is roughly 200 times bigger than the chips you'd find in most PCs, making it the largest imager ever made on a wafer of standard, eight-inch diameter. This extra girth allows the active pixel sensor to capture images in high detail, with a 100-micrometer pitch boasting 1280 x 1280p aligned next to a 50-micron layer, carrying 2560 x 2560p. DyNAMITe can also run at up to 90fps and withstand high levels of radiation for several years, making it ideal for medical imaging, including radiotherapy and mammography. Researchers say these enhanced images could help doctors detect cancer in its earliest phases, while allowing them to monitor radiotherapy treatments more closely. No word on when we should expect to see DyNAMITe pop up in hospitals (or a Hasselblad back), but physicists at the Institute of Cancer Research and Royal Marsden Hospital are busy looking for other, potentially life-saving applications. Full PR after the break.
Amar Toor05.06.2011OmniVision's OV10810 image sensor handles 1080p video recording, 10 megapixel image capture
OmniVision has just let loose its OV10810, hailed as the first native 16:9 CMOS image sensor to enable simultaneous 1080p HD video recording and ten megapixel image captures. The chip is built upon the company's 1.4-micron OmniBSI pixel architecture, and it's obviously aimed at digicams, camcorders and higher-end smartphones. Generally speaking, any camcorder that can snag stills on the side does so at a terribly low resolution, but this bantam slab of silicon would obviously serve as a solution. The technobabble's there after the break if you're interested, and you can commence waiting for this to make it to your favorite smartphone / camera maker... now.
Darren Murph01.10.2011Sony buys back Toshiba's Cell plant for 50 billion yen, makes a killing and plans a CMOS fab
Looks like Toshiba's Cell processor ambitions didn't quite pan out -- Japanese news sources are reporting that the company's selling its Nagasaki manufacturing plant back to Sony for 50 billion yen, or roughly $597 million in US money. Considering that Toshiba originally purchased the semiconductor facility for 100 90 billion yen (then $835 million) back in 2008, it seems like Sony's making out like a bandit here -- and it may have just found the perfect place to build more CMOS chips for its high-end camera lineup, too. Sony reportedly told the Nikkei Business Daily that it may repurpose the facility to produce HD image sensors for cameras and smartphones. What will happen to the chip that launched 40 million PS3s and a graphics co-processor or two? With any luck, we'll find out at CES 2011 quite soon.
Sean Hollister12.22.2010Sony outs world's first 16.41 megapixel cellphone sensor
Uh, wow, guess the megapixel race isn't over. Sony just announced the world's first 16.41 megapixel CMOS sensor for mobile phones putting today's 12 megapixel units to shame. The 1/2.8-inch back-illuminated Exmor R model IMX081PQ sensor packs an industry smallest 1.12μm unit cell size and is capable of shooting 1080p at 30fps or 720p at 60fps. Sony claims to have solved some of the issues related to those incredibly small pixel sizes by implementing a unique formation of photo diodes to achieve a sensor with high resolution, high sensitivity, and low noise. Expect it to begin sampling in January 2011 for ¥2,500 (about $30) per or ¥12,000 (about $145) when packaged with a 10.5 x 10.5 x 7.9 mm IU081F autofocus lens module that ships in March -- prices that will come down dramatically when purchased in bulk. A second, 1/3.2-inch 8.13 megapixel IMX105PQ sensor with IU105F2 lens module (pictured on the right) will be out in April for a lot less.
Thomas Ricker10.07.2010Sony outsourcing some image sensor production to Fujitsu
Whoa. Sony sure didn't mention anything about this at its Photokina press conference last week, but then again, it's not the most glamorous announcement to make. According to Reuters, Sony is aiming to "outsource some production of image sensors used in digital cameras and mobile phones to Fujitsu," and as you'd expect, it's being done in a bid to shave costs and "cope with tough global competition." According to a Sony spokesperson, the company has been mulling this decision for awhile, but it's unclear if this will have any further impact in Sony's employment numbers. It's also unclear why "some" sensor production will remain internal -- we're guessing that newfangled Translucent Mirror technology may have convinced the firm to keep the DSLR lines a bit closer to the chest. It's bruited that Sony will begin subcontracting output to Fujitsu later in the year, and it could shift even more output if things go swimmingly. Funny enough, an eerily similar scenario hit Sony's LCD department back in early 2008. What's next? Subcontracting Walkman production to Apple?
Darren Murph10.01.2010Samsung announces 1080p in-bezel CMOS sensor, webcam spying going HD
Next time you hit your local electronics emporium, you might just find the HD moniker attached to an unfamiliar category: bezel-integrated webcams. Samsung's newly announced S5K6A1 CMOS sensor can perform 720p video recording at 30fps or shoot 1.3 megapixel images, while its senior sibling S5K5B3 elevates those values to 1080p / 30fps and 2.1 megapixels, respectively. Touting an autofocus feature that helps with reading barcodes and business cards as well as improved low-light performance, Samsung tells us these new must-have laptop parts are set for mass production in the second quarter of this year. Samples are available today, so if your name's Michael Dell or Arimasa Naitoh, why not give Sammy a call?
Vlad Savov04.09.2010New Samsung chips bring HD image sensors to slimmer, smarter mobiles
In case you haven't noticed, Mobile World Congress is upon us, and you can bet that Samsung is here in a big way. The outfit is kicking things off with a couple of low-key releases: the S5K4E2 and S5K5CA CMOS image sensors. The former is a 5 megapixel chip that utilizes Samsung's own Enhanced Energy Steering technology and can capture video at up to 15 frames per second. We're told that it's also pretty darn good at reducing noise, and better still, it can slip into some of the slimmest and smallest handsets this world has ever seen. Moving on, there's the S5K5CA SoC imager, a 3 megapixel chip that combines both the image signal processor (ISP) with the CMOS image sensor. As the story goes, this one's some 25 percent smaller than prior 3 megapixel chips and the 720p video capture capabilities aren't too shabby, either. Both slabs are expected to hit mass production later this year, so go ahead and get ready to break the bad news to your existing cameraphone now. It's better this way, we promise.
Darren Murph02.14.2010Sigma acquires Feveon, maker of the X3 image sensor
Foveon (developer of the X3 image sensor for digital cameras) has just announced that they have been acquired by Sigma, the Tokyo-based camera and lens company. According to the press release, Foveon -- whose image sensors are already being used in Sigma's entire digital camera line -- will remain in San Jose, continuing to "evolve and improve the X3 sensor technology." Congratulations, you crazy kids! And best of luck to you. We mean it.
Joseph L. Flatley11.11.2008Kodak rolls out new image sensors at Photokina, one for Leica's S2
We noticed that the writeup for Leica's newly unveiled S2 made mention of a new Kodak sensor, but we'll leave it to Kodak to do the boasting. Sure enough, the outfit responsible for this atrocity has rolled out a few new image sensors at Photokina 2008, one of which -- the KAF-37500 -- proudly resides in the aforementioned S2. The company is showcasing sensors for medium format rigs such as the Sinar HY6-65 (KAF-31600) and Hasselblad H3DII-50 (KAF-50100), though quite honestly, it spends more time gloating about what manufacturers it's partnering with than describing the technology. Oh well, so long as it keeps Kodak from focusing on its pathetic point-and-shoot lineup, we'll keep smiling.
Darren Murph09.24.2008Thomson intros 9211 HD CMOS image sensor with Full HD resolution
Not that you'll see one of these in your next digicam or anything, but Thomson's latest HD CMOS image sensor could still make the world you watch a lot clearer in due time. The 9211 is currently aimed at industrial applications such as machine vision, medical imaging and high-end video surveillance, and even offers up the ability to capture pixels in progressive or interlaced formats. As expected, this device features a 1,920 x 1,080 resolution and on-chip dual 12-bit A/D converters, but who knows how long it will be before your every step in a Las Vegas casino is logged in 1080p.
Darren Murph02.19.2008Kodak introduces "world's first" 1.4 micron, 5-megapixel CMOS sensor
Kodak claims to be "revolutionizing" image capture, though you always have to take press releases with a grain of salt. However, it does appear that the company has made some interesting advances in camera technology for mobile devices, which will hopefully lead to bigger and better images from our phones in the near future. The company's new KAC-05020 snaps its proprietary Color Filter Pattern technology together with a redesigned CMOS pixel for the "world's first" 1.4 micron, 5-megapixel device. The new sensor shrinks the pixels down, but manages to maintain picture quality by harnessing the aforementioned CFP. That technique adds a fourth layer of "clear" pixels to the red, green, and blue ones which already exist, thus collecting a higher proportion of light striking the sensor, improving low light photography, reducing blur, and generally making you look like Ansel Adams. The chip is also capable of 720p video at 30 FPS, as well as extreme low light settings, like ISO 3200. Kodak will be showing the new technology off at the Mobile World Congress this month, and then hopefully cramming it into phones for us very, very soon.
Joshua Topolsky02.04.2008Sharp's latest 2.6-inch LCD touts integrated touch sensor
We know you were probably delighted by Asahi Kasei's Rain Sensor, but Sharp is taking its sensors to a more sophisticated realm with its latest LCD. The 2.6-inch panel has been primarily designed for use in mobile / portable applications, and aside from sporting a 640 x 480 resolution, it also "incorporates an image sensor in the drive circuit." The sensor, which boasts a frame rate output of 30Hz, would allow companies to offer up "touchscreen input and biometric capabilities" in mobile devices, and although other firm's have offered up somewhat similar offerings -- not to mention thrown down a eerily similar patent application -- Sharp's rendition claims uniqueness by integrating the image sensor with the drive circuit of the panel and by using a "one transistor, one capacitor (1T1C) circuit structure" to boot. No word on when we'll see these fingerprint reading screens in cellphones or PMPs, but there's always the vibrating kind for those who just can't get enough functionality out of their mobile display.
Darren Murph02.16.2007DALSA ships 111 megapixel CCD
Don't expect to see one of these in a commercial DSLR anytime soon (especially now that Mamiya has left the game), but a division of DALSA Semiconductor has successfully manufactured and delivered a 111 megapixel image sensor that's only been topped on these pages by the 500 megapixel monster inside Fermilab's Dark Energy Camera. Putting even the highest-resolution bacteria-based cam to shame, the new 4-inch-square CCD features an array of 10,560 x 10,560 pixels, and was developed in conjunction with Semiconductor Technology Associates to aid the U.S. Naval Observatory's Astrometry Department in precisely determining the position and motion of celestial objects. While you probably can't afford to hire DALSA to build another one of these just for you, there's at least one option on the market that will give you the hundred-plus megapixel bragging rights you seek without breaking the bank: Better Light's 144 megapixel E-HS medium format backing, which, while technically only capturing 48 megapixels per color (and taking at least 66 seconds to do so), should still be enough to impress even your EOS 1Ds Mark II-sporting friends.
