Panasonic ToF DImager Product Line

Panasonic-affiliated web site Pidtechinsights posted an nice explanation of the differences in DImager product lineup:

Currently, three different D-IMagers are available—Models 3104, 3105 and 3106. All three have some common characteristics, but they differ in some key regards:
  • Lighting Requirements. The original D-IMager, Model 3104, serves in lighting conditions up to 20,000 lux. So does the Model 3105, though it has a higher sensitivity than than 3104. Model 3106 addresses high illumination applications—up to approximately 100,000 lux. To date, the 3106 is the only commercially available IR ToF sensor that can be used with such high illumination levels.
  • Pixel Format. All D-IMagers have a nominal pixel format of 160 x120. They have a minimum measurement range of 1.2 meters. Maximum measurement range is 9 meters for Models 3104 and 3106. Model 3105 has a maximum range of 5 meters.
  • Frame Rate. All three models offer frame rates of 15, 20, 25 and 30 fps.
  • Field of View. The further the target is away from the camera the greater field of view (FoV) angle and the lower the resolution. In most applications, FoV above 60 degrees can easily be balanced with the resolution needed for gesture or movement tracking applications.

Toshiba Develops 4.7mm-thin 13MP Camera Module

VR-Zone quotes Japanese language IT Media saying that Toshiba unveiled on March 28, 2013 a new 4.7mm-thin 1/3.07-inch camera module aimed to smartphones and tablet computers. It is designated as the TCM9930MD, and Toshiba claims that it is currently the world's thinnest 13MP camera module.

Samples of the camera module will be available at around May 2013. Mass production of the modules is projected to start in December 2013.


Tech-on adds that the TCM9930MD lens consists of four plastic elements, and a dedicated signal processing circuit is used to compensate for the lens distortion and restore MTF in the peripheral area of an image.

Also, Toshiba used a flip chip instead of a wire bonding to further reduce the thickness of the module.

Update: PR Newsire: Achieving today's high-resolution requires a larger optical size for corresponding lenses which results in a thicker camera module and a bulkier mobile device. The conventional method for lowering the camera module height is to modify the optical lens design which becomes problematic due to resolution drop around the corners of the image area. The TCM9930MD, however, resolves this drop in resolution with the use of the image pre-processing LSI (companion) chip that provides distortion correction and performs image resolution reconstruction (Resolution reconstruction is a super-reconstruction technology developed by Toshiba Corp. R&D center). Additionally, the TCM9930MD achieves its low profile by using a flip-chip structure for the image sensor. Toshiba opted to use flip-chip packaging because it allows for a large number of interconnects, with shorter distances than wire, which greatly reduces assembling area and package height.

Toshiba to Launch 1080p60 Video Sensor with 1.12um BSI Pixels

Business Wire: Toshiba announced 1/7.3-inch 1080p60 sensor based on 1.12um BSI pixel and integrating a color noise reduction (CNR) circuit. Samples will be available at the end of April with mass production scheduled to start in September 2013.

The new T4K71 sensor is said to achieve a SNR equal to Toshiba's existing 1.4um pixel product. It enables chip and camera module miniaturization and will contribute to achieving thinner smartphones and tablets.

The T4K71 was mentioned in the former Toshiba PR, so this one mostly re-iterates and expands on the previous info.


Update: PR Newswire: Sample pricing for the T4K71 CMOS image sensor is $8.00. Samples will be available by the end of April 2013, with mass production scheduled to begin in September 2013.

Tessera DOC to Focus on Lens Barrel Manufacturing

Business Wire: Tessera announces that it is refocusing its DigitalOptics Corporation (“DOC”) business strategy:
  • DOC will accelerate the use of partner manufacturers for the production of camera modules and will focus its own manufacturing on the lens barrel assembly, which is a higher-margin component for which DOC has unique proprietary technology. This approach will cut DOC’s expected capital spending in 2013 by roughly half – to a range of between $5 million and $7 million, as compared to the Company’s previous estimate of $10 million to $15 million.
  • DOC is consolidating its manufacturing capabilities into its Taiwan facility and expects to cease all operations at its leased facility in Zhuhai, China. DOC will transfer a portion of the manufacturing equipment located there to Taiwan.
  • DOC will terminate its current lens manufacturing program and instead will focus on designing lenses that its partners can produce for use in DOC’s proprietary assembly technology.
  • The Company expects to take a total charge of between $17 million and $23 million, which includes restructuring, impairment of assets and other related exit costs, with the majority taken in the first quarter of 2013 and the remainder in the second quarter of 2013.

The Company has determined that it is no longer necessary for DOC to be a vertically integrated camera module supplier. DOC will instead focus its strategy on the differentiated MEMS-related technologies, where it has proprietary assembly technology and expertise, and will partner with third-party manufacturers to produce other components of the full camera module. DOC will continue to productize the mems|cam technology throughout the rest of the year, and expects to ship small production volumes of its technology in 2013.

The refocused DOC strategy and restructuring resulted from a business strategy review directed by a committee of independent directors, led by Richard S. Hill, former chairman and CEO of Novellus Systems. The Committee worked with management to evaluate the Company’s overall business opportunity, strategy and operating model. The Committee and the Board of Directors will continue to monitor the DOC business closely to ensure that its strategy and business model are appropriate for the market opportunity.

Fujitsu Measures Pulse from Face Video Stream

Tech-on: Fujitsu Labs pesented an interesting application to measure pulse by using video of a human face in real time.

The new technology detects pulse based on color elements of video by exploiting the fact that hemoglobin in blood absorbs green light and detecting color change on a facial surface caused by blood flow. An influence of facial and body movements (such as talking on the phone) is automatically removed.

"At the fastest rate, it can measure pulse in five seconds," said Yoshinori Yaginuma, director, Human Solutions Laboratory, Human Centric Computing Laboratories, Fujitsu Laboratories. "The maximum margin of error is about ±3 heart beats per minute."

"The required resolution is VGA or so," he said. "Twenty frames per second are enough. So, a camera of a personal computer, tablet computer or smartphone is sufficient."

The company is considering using the technology for simple health checkup at home, monitoring elderly people, automatic health problem detection in offices and detection of sick people and suspicious individuals in airports or at gates at event sites.

CMOS Sensor Market Grows, CCD Market Declines

The latest IC Insights report talks about CMOS sensor market status:

"CMOS image sensors were [one of the] fastest growing product category in 2012 with sales rising 22% to a new record-high $7.1 billion, blowing past the previous peak of $5.8 billion set in 2011. Since the 2009 downturn year, CMOS image sensor sales have climbed 85% due to the strong growth of embedded cameras used in smartphones and portable computers (including tablets) and the expansion of digital imaging into more systems applications. CMOS designs are now grabbing large chunks of marketshare from CCD image sensors, which are forecast to see revenues decline by a CAGR of 2.4% between 2012 and 2017. Sales of CMOS imaging devices are projected to grow by a CAGR of about 12.0% in the forecast period and account for 85% of the total image sensor market versus 15% for CCDs in 2017. This compares to a 60/40 split in 2009."

Photon Absorption Generates Multiple Electrons in Graphene

ISFO, Eurekanet: Nature Physics' paper authored by ICFO researchers, in collaboration with researchers from MIT, Max Planck Institute for Polymer Research, and Graphenea S.L. demonstrates that graphene is able to convert a single photon that it absorbs into multiple hot electrons, and that the higher photon’s energy, the larger the number of hot electrons created:

"Photoexcitation cascade and multiple hot-carrier generation in graphene"
K. J. Tielrooij, J. C. W. Song, S. A. Jensen, A. Centeno, A. Pesquera, A. Zurutuza Elorza, M. Bonn, L. S. Levitov & F. H. L. Koppens

Apparently, this is possible due to a very small bandgap in graphene, so that photoelectrons can use their excessive energy to multiply themselves - somewhat similar to X-ray absorption in silicon.

Not everything is good about graphene photodetectors. An earlier article in Economist from the same group says that graphene only captures 2.7% of the photons falling on its surface. There are some ways to improve it though.

Toshiba Image Recognition Processor Targets ADAS, Industrial Applications

Toshiba: The European New Car Assessment Programme (Euro NCAP) requires automobile companies to introduce autonomous braking systems in 2014. These will initially cover other vehicles, and will be extended to include pedestrians in 2016. Initiatives like this are expected to spur 50-100% growth in the global market for image recognition processors between fiscal 2010 and 2015, from 75 to 100 billion yen.

In preparation to this Toshiba announces Visconti 3 series of automotive image recognition processor. The first device in this new series, TMPV7528XBG, is expected to extend its use beyond automotive to industrial applications.

Toshiba initially developed the Visconti series of image recognition processors to advance the creation of camera-based vision systems for automotive applications. The processors recognize traffic lanes, vehicles, pedestrians, traffic signs and more and both the Visconti 2 and 3 series devices incorporate image processing accelerators that detect pedestrians with high level detection ratio in real time.

In addition to these capabilities, the Visconti 3 integrates 2-core ARM A9 processor dedicated to supporting applications interfacing with the image recognition processor. With Visconti 3, Toshiba will seek to expand the image recognition processor business beyond automotive systems into camera-based vision systems for industrial applications. The company targets annual sales of 2 million Visconti image recognition processors in fiscal 2015.

Sample shipment of Visconti 3 will start in April 2013.

Canon Announces Full HD Video Sensor with 19um Pixels

Canon announces a high-sensitivity 35 mm full-frame CMOS sensor developed exclusively for video recording. Delivering high-sensitivity, low-noise imaging performance, the new sensor enables the capture of Full HD video in exceptionally low-light environments.

The sensor pixel size is 19um, more than 7.5-times the surface area of the pixels on the CMOS sensor incorporated in Canon's top-of-the-line EOS-1D X and other digital SLR cameras. In addition, the sensor's pixels and readout circuitry are said to employ new technologies that reduce noise, which tends to increase as pixel size increases. Thanks to these technologies, the sensor facilitates the shooting of clearly visible video images even in dimly lit environments with as little as 0.03 lux of illumination, or approximately the brightness of a crescent moon—a level of brightness in which it is difficult for the naked eye to perceive objects. When recording video of astral bodies, while an electron-multiplying CCD, which realizes approximately the same level of perception as the naked eye, can capture magnitude-6 stars, Canon's newly developed sensor is capable of recording faint stars with a magnitude of 8.5 and above.

Using a prototype camera employing the newly developed sensor, Canon successfully captured a wide range of test video, such as footage recorded in a room illuminated only by the light from burning incense sticks (approximately 0.05–0.01 lux) and video of the Geminid meteor shower. The company is looking to such future applications for the new sensor as astronomical and natural observation, support for medical research, and use in surveillance and security equipment.

Seeking Alpha published Omnivision earnings call transcript. An interesting quote:

Hans Mosesmann - Raymond James:

Can you confirm that the BSI-2 yields are where you need them to be and if not how long will that take for us to see that?

Shaw Hong - CEO:

I think we are very comfortable with what we have done to date in terms of coming up with improvements on the production yield ...the yield should not be much of a concern for any one, but I do want to point out is that if in case you want to take this comment to project our next year's performance, likely we will be introducing new SKUs with the producing different parts by then. So essentially, our operation team we have to go through another cycle of yield improvement process.
