Samsung and Sony Divide Fight for Mobile CIS Market

Business Korea published an article on Samsung efforts to capture mobile CIS market. TSR predicts that Samsung will take the lion’s share of the mobile CIS market this year, capturing 24.5% market share by supplying 548.325M CIS units. Sony’s supply volume and market share are estimated at 410.84M units and 18.4%, respectively.

For now Samsung is focusing on mid-end and high-end products of less than 8MP. Although it does produce those that can capture eight or higher megapixels, these account for less than 20% of the total sales volume. Meanwhile, products of 8MP to 13MP represent over 70% of Sony’s total sales.

"Sony’s CISs are at least 1.5 times more expensive than those of Samsung Electronics and OmniVision. Almost all of the high-end smartphones in the market are equipped with CISs manufactured by Sony," said unnamed market expert. Sony’s brand power is said to be greater than Samsung’s when it comes to high-price products of 8MP to 10MP.

Panasonic Sells Some of its Fabs to TowerJazz

Reuters, Bloomberg, Globes: Panasonic is reported to sell its three Japanese fabs to TowerJazz. It's not immediately clear whether Panasonic sells its image sensor plants. "The companies are negotiating the size of the stake and transfer of the factories' workers, one of the sources said. The three chip plants in Japan, with about 2,500 workers, have been fully depreciated and had a combined book value of 42.2 billion yen ($416 million) as of March 31.

Panasonic said nothing had been decided. Officials at TowerJazz's headquarters could not immediately be reached." "The plants are likely worth more than 10 billion yen ($99 million), and a final decision may come as soon as next month."

So far Panasonic has more than 3 fabs in Japan, not clear which ones go to TowerJazz:

Meanwhile, image sensors are presented as one of the core technologies at Panasonic site:

Imagers in Space, Imec's View

EETimes: Piet De Moor, Program Manager for Specialty Imagers at Imec published a view on CMOS vs CCD for space applications: "While CMOS has become the standard in consumer electronics, the space community is still mainly relying on CCD technology. In part, that's because backside illumination processing for CMOS imagers is almost uniquely developed for 300mm wafers [probably Piet meant Imec process offerings here - ISW], whereas high-end space imagers typically use 200mm wafer technologies.

However, the space industry would well be served with a customized high-end backside illuminated CMOS imager processing platform on 200mm wafers. Given the strategic value of Earth observation, it is not surprising that governments on both sides of the Atlantic are currently supporting local initiatives in this area."

MIT Presents Coded ToF Camera

MIT News: Ramesh Raskar, Achuta Kadambi, Refael Whyte, Ayush Bhandari, Christopher Barsi from MIT and Adrian Dorrington and Lee Streeter from the University of Waikato in New Zealand presented a new ToF camera at SIGGRAPH Asia 2013: "Coded Time of Flight Cameras: Sparse Deconvolution to Address Multipath Interference and Recover Time Profiles."

"Using the current state of the art, such as the new Kinect, you cannot capture translucent objects in 3-D," says Achuta Kadambi. "That is because the light that bounces off the transparent object and the background smear into one pixel on the camera. Using our technique you can generate 3-D models of translucent or near-transparent objects." Changing environmental conditions, semitransparent surfaces, edges, or motion all create multiple reflections that mix with the original signal and return to the camera, making it difficult to determine which is the correct measurement.

The new ToF camera uses an encoding technique commonly used in the telecommunications industry to calculate the distance a signal has travelled. "We use a new method that allows us to encode information in time," Ramesh Raskar says. "So when the data comes back, we can do calculations that are very common in the telecommunications world, to estimate different distances from the single signal."

"By solving the multipath problem, essentially just by changing the code, we are able to unmix the light paths and therefore visualize light moving across the scene," Kadambi says.

A Youtube video demo visualizes the light travel, including multi-path resolving on semi-transparent objects:

Dongbu Starts Mass Production of 5MP Sensor for Superpix

Business Wire: Dongbu HiTek has begun volume production of 5MP Image Sensor for Superpix Micro Technology of Beijing, China. With patented SuperPix pixel signal processing and SuperImage image processing techniques, Superpix anticipates strong demand for its 5MP CIS devices in China’s mid-range to low-end smart phone market segments.

"We continue to expand our foundry relationship with Superpix, and are now on track to begin developing its 8MP CIS chips early next year so that volume production can also begin next year," said Jae Song, Dongbu HiTek EVP of marketing. He noted that his company’s foundry relationship with Superpix has progressively developed from manufacturing QVGA/VGA chips to the 2MP–to-8MP range.

According to Maybank, the Chinese smart phone market in the mid-range to low-end segment is forecast to grow from some 216M units shipped this year to about 400M units in 2015, thereby exceeding 85% growth over the two year period. In another forecast from iSuppli, smart phones that feature 5MP resolution and above will substantially command this segment’s growth as they replace 2M resolution cameras, shipping 187M units next year and 288M units in 2015, representing a year-over year growth of more than 50%.

Apple Confirms Primesense Acquisition

AllThingsD gets a confirmation from Apple that it has bought Primesense for a price closer to $360M, according to ATD sources:

Apple spokeswoman Kristin Huguet confirmed the PrimeSense deal with the boilerplate comment the company typically provides when news of one of its acquisitions leaks: “Apple buys smaller technology companies from time to time, and we generally do not discuss our purpose or plans.”

Globes reports that the deal was finally closed on Friday, Nov. 22.

Update: Primesense confirms the acquisition in an email to EETimes-Europe: "We can confirm the deal with Apple. Further than that, we cannot comment at this stage."

Rambus Lensless Camera Paper Wins Best Paper Award

Rambus announces that its paper "Lensless Ultra-Miniature CMOS Computational Imagers and Sensors" by David Stork and Patrick Gill won Best Paper Award at Sensorcomm 2013, held in Barcelona, Spain in August 2013. Rambus' "method relies on novel special phase anti-symmetric spiral phase gratings, which overcome prior limitations and afford new functionality. Moreover, our new sensor architecture enables the construction of new classes of ultra-miniature sensors whose output is an estimation of some property of the scene (e.g., visual motion) or a decision (e.g., face detection or barcode reading)."

"These imagers promise to be smaller (lower physical volume) than any existing lens-based imagers of comparable resolution, very inexpensive, and customizable to both imaging and a wide range of sensing and image measurement tasks."

Global and China CMOS Camera Module Report, 2013

Research-In-China has updated its "Global and China CMOS Camera Module Industry Report" with 2013 data. A few key statements from the report:

• The growth rate of cell phone camera pixels slows down, or even declines in 2013.
• OIS is widely used in high-end phones: HTC (one), SONY (Xperia ZU), LG (G2 flagship) and Google (Nexus5)
• Tablet PC shipment has shown the signs of touching the ceiling, and its future growth will be sluggish.
• The automotive CCM shipment totaled 24,946,000 sets in 2012 and will grow by 56.4% year on year to 39,008,000 sets in 2013. The shipment is expected to maintain rapid growth, reaching 59,632,000 sets with the increase of 52.9% in 2014. The automotive CCM market is dominated by Panasonic, Sony, Magna, Valeo, MCNEX, Gentex, Fujitsu, Continetal and Autoliv.
• Without taking DSC into account, CMOS camera modules market is about USD13 billion in 2013, up 28.7% from 2012. Themarket is expected to hit USD15.9 billion in 2014, representing a year-on-year increase of 22.3%, mainly because of the adding of higher pixels and more complex features such as OIS.
• At the image sensor market, Omnivision, Samsung and Sony compete with each other fiercely. Sony firmly occupies the high-end market, especially the market of 13MP and bigger pixel size; Omnivision's revenue in FY2013 surged by 56.8% from the figure in FY2012 by virtue of low prices, but with profit sacrifice. Aptina transfers to less competitive non-handset markets.
• Largan almost monopolizes the beyond-8MP lens market. Its gross margin and operating margin jump from 2012 and the revenue is approaching USD1 billion. The revenue of the second-ranked GSEO falls to less than USD350 million in 2013.
• Taiwanese camera module vendors LITEON, PRIMAX and CHICONY are facing weak growth. However, Chinese and South Korean vendors are developing triumphantly, especially South Korea ones. LG INNOTEK has achieved the world's first laureate again, mainly serving Apple whose at least 70% CCM comes from LG INNOTEK. Taiwanese vendors can only snatch Apple's orders for low-end products. SEMCO's revenue soars thanks to Samsung's handset shipment surge; by profit, SEMCO acts as the world's largest CCM vendor.
• Among Chinese mainland vendors, SUNNY witnesses the strongest growth, and its shipment in 2013 is expected to reach 136 million units, doubling that in 2012. Besides, South Korean vendors also push aggressively into Chinese market, for instance, MCNEX is ZTE's largest supplier and Cowell acts as Lenovo's supplier.

Imagination Announces Raptor ISP IP

Imagination launches its PowerVR Series2 ‘Raptor’ architecture for an image signal processor. The initial architectural family announcement will be followed up in due course with core IP family members aimed at specific markets. The ‘Raptor’ interfaces directly to a CMOS sensor – no need for a stacked ISP on the sensor chip itself – and it includes all of the functions needed to prepare images or streaming videos for insertion into a real-time encoder or display to the viewfinder. Included in the pipeline hardware are a set of powerful, configurable image processing blocks to handle the “three A’s” (Auto focus, Auto Exposure, Auto White Balance) in hardware but controlled by the CPU for maximum flexibility.

‘Raptor' includes tunable blocks to correct for various lens aberrations, for variations in illumination across the sensor surface, to remove noise introduced by very high density sensors in low light and to remove bad pixels. Then the raw image turned into an RGB image and tuned for the characteristics of the sensor before being sent off for display and/or encode. All of these operations are said to be done in the most configurable way possible in order to interface to the widest selection of CMOS sensors.

The job of the ISP is evolving rapidly away from being a simple image or video capture device; forward looking features of the ‘Raptor’ architecture include the ability to interact with other powerful vision and video processors in the multimedia subsystem. One example of this is a dedicated interface to a PowerVR video encoder in order to implement low latency video encode for live video conferencing; another is the production of image statistics, or hints, which can be used for a range of imaging and vision enhancements.

Computational photography using the GPU for heavy duty processing is already within the range of the abilities of ‘Raptor’, and forward looking applications include vision applications using multi-camera arrays (‘Raptor’ can simultaneously support multiple sensors with widely different characteristics) as well as higher pixel depth applications for industrial and automotive use. In its most cost-efficient form, ‘Raptor’ supports 10-bit pixel depths which matches the 10-bit encode and decode capability already offered by PowerVR video processors. It can be configured to support much higher bit depths (up to 16) when needed.

TowerJazz Reports Imminent Launch of High-Volume Gesture Control Sensor

SeekingAlpha publishes TowerJazz Q3 2013 earnings call transcript updating on its CIS business:

"In our CMOS Image Sensor business unit, we continued to see growth from our leading European customers for high-resolution, high frame rate, global shutter products. This is a highly competitive field, however, most of the competition is not between us and other foundry providers, but rather between our customers. There are many growth, as well as new applications for industrial cameras, such as traffic control, 3D copiers and border control that contribute to our overall market growth. The continuous move from CCD to CMOS in the industrial sensor market also contributes to the growth of this area of our business.

In the x-ray market, we reported in the past on prototypes of several new sensors for medical and dental applications. Those products are currently ramping nicely to production and are expected to contribute significantly to the CIS business unit's revenue next year and beyond. Several new projects are in the pipeline and considering the very long life of x-ray sensor products in general, we expect the products to be responsible for substantial incremental revenues over the next 5 to 8 years.

Our forecasted high-volume gesture control project is now in its qualification stage and moving according to plan. The gesture activities are with name-brand top-tier customers. This is expected to ramp to mass production next year. We're also making significant steps in the high-end scientific and space sensor area. In the beginning of October, we presented our technology to the CERN Institute in Switzerland and were personally congratulated by the CERN General Director for winning a $5 million contract to supply sensors to the new CERN experimental facility, known as ALICE. We expect to penetrate more into the research in space area in Europe during 2014.

In addition, just last week, we announced that together with SRI International, we delivered the first radiation-hardened CMOS image sensor units to the Naval Research Laboratory for use on the Solar Orbiter Heliospheric Imager, known as SoloHI optical telescope. SoloHI is part of the NASA and European Space Energy, Solar Orbiter Mission. Planned for launch in 2017, the spacecraft is expected to study the sun from a closer distance than any other previous mission, and we are proud to be critically involved in this mission. Although itself not a high-revenue project, it does recognize our technology leadership and brand in a scientific grade rad-hard image sensors."

Nokia Emulates Pelican and Lytro Refocusing Function

Nokia Conversations blog tells about a new downloadable application available for Lumia 920-series and 1020 camera phones - Refocus. The application essentially emulates the post-capture refocus capability available in Lytro and Pelican Imaging cameras:

"Once you have the closest object in focus, tapping the screen on your Lumia will start the capture process – which only takes a couple of seconds (try to be very still). During this time, Nokia Refocus performs a ‘focus sweep’ and creates a depth map.

This new way of taking photos is a great example of computational photography. We’ve now got the ability to change a photo once it’s taken and have a photo that simply couldn’t have been taken by a traditional camera.

The result is a series of 2-8 images, depending on what’s in view, each at five megapixels at a different focus that’ll be aligned and forged together to make one image.

By tapping on any part of this final image you’ll be able to shift the focus to that particular part. The great thing here is that you can achieve a variety of different shots from just the one photo."

Refocus app can also put the whole scene into focus at the same time to provide extra clarity:

Engadget says that Refocus is based on Scalado technology that Nokia acquired a year ago.
