Korean news agency Yonhap gives its view on Sony and Samsung market shares, also quoted by Business Standard and MSN:

"Sony and Samsung currently lead the global market for CMOS image sensors, with the Japanese rival holding a slight edge.

In 2016, Sony and Samsung took up 25.6 percent and 22.6 percent of the market, respectively, industry data showed.

The two companies held 28.3 percent and 25.4 percent, respectively, last year. SK hynix Inc., Samsung's smaller South Korean rival, accounted for roughly 8 percent to 9 percent over the cited period.

Industry watchers, however, claim Sony takes up 50 percent of the market in terms of sales, hovering far above Samsung's 20 percent."

Mydrivers: A number of Chinese news sites cover Oppo May 10th meeting devoted to the company work on the 3D sensing for smartphones. Unfortunately, most of the information is in Chinese, but one can understand that Oppo is preparing structured light based 3D face recognition and in many other applications too. The 3D camera is said to be mass production ready and Oppo plans to launch first phones with it in the next 6 months:

More Info on SensL Acquisition by ON Semi

The Irish Times times publishes an article on ON Semi acquisition of SensL:

"Financial details of the transaction have not been disclosed but industry insiders told The Irish Times it was a “high double-digit deal”. The Bank of Ireland-backed Delta fund had a 45 per cent stake in the company prior to the acquisition with management and employees owning the bulk of the remaining shares.

SensL, whose clients include the European Space Agency, was spun out of the Tyndall National Institute in 2004. It was founded by Carl Jackson and Joe O’Keeffe, the latter of whom went on to enjoy success as a founder of Infiniled, which was acquired by Facebook-owned Oculus VR in 2016. SensL, which is now led by Bryan Campbell, employs 25 people in Cork.

“We built the company making optical sensors that can be used in a whole bunch of different products,” Mr Jackson told The Irish Times.

“We built the business on the back of our involvement in medical imaging, where we developed a key sensor that goes into PET scanners. We’re also active in radiation detection, and three years ago started working on lidar products for the automotive market. This will be one of our core focuses going forward,” he added.

While SensL’s autonomous car technology was one big attraction for On Semiconductor, Mr Jackson stressed that the buyer was interested in all of its product lines."

LFoundry 2017 report contains interesting info about the foundry, its customers, and the relationships with its mother company SMIC:

"The year began with the clear, challenging objective of equipping the Avezzano plant with further, alternative production capacity compared to its traditional focus on image sensors, made necessary by the growing demand from China and Asian markets.

This demand, however, then saw a sudden turnaround, and, at the same time, a strong increase in the request for image sensors on the part of our largest, long-standing customer. Therefore, we spent the second part of 2017 involved in another important company reorganisation process, undertaken in order to guarantee this long-established customer sufficient supplies to meet their growing demand for image sensors.

Today, LFoundry is an increasingly strong candidate to become a SMIC centre of excellence for CMOS Image Sensors, and to take on the role of strategic partner of the world leaders in the application of image sensors in the automotive field."

Omnivision Announces Design Win in Automotive Eye and Gaze Tracking Camera

PRNewswire: OmniVision collaborates with Smart Eye to integrate its automotive 2MP image sensor with Smart Eye's sensing algorithm library in a turnkey driver and cabin monitoring solution that targets automotive OEMs.

"Automotive OEMs need image sensors that are certified to ASIL B for level-3 autonomous vehicles, beginning with 2021 models," said Marius Evensen, senior automotive technical marketing manager at OmniVision. "The OV2311's ASIL B certification includes advanced safety features."

Eye- and gaze-tracking cameras need to be small and unobtrusive so that drivers do not feel they are being monitored, but smaller cameras tend to run hot and create excess system noise. The OV2311 sensor in a chip-scale package consumes half the power of competing 1MP solutions, keeping the temperature under control without sacrificing performance. Its high pixel density enables a wide field of view for a larger headbox to adjust for various driver seat positions, along with precise images for tracking gaze. Additionally, the wider field of view opens the opportunity for sensing throughout the cabin interior, including passengers as well as the driver.

"OmniVision's OV2311 is now the benchmark for the driver monitoring industry. Our combined solution benefits automotive OEMs needing a complete hardware and software package that has been thoroughly tested and is ready to implement in a wide variety of vehicles," said Karolina Wikander, head of business management at Smart Eye.

Framos SLVS-EC RX IP Core shortens design time with the latest generation of Sony image sensors. The SLVS-EC interface (Scalable Low-Voltage Signaling with Embedded Clock) has up to 8 lanes and 2.376 Gbps throughput per lane. When compared to Sony’s 2nd-generation CMOS image sensors with S-LVDS interfaces, the SLVS-EC interface doubles the overall output speed to 19 Gbps. SLVS-EC has more than three times higher bandwidth per lane.

Machine Learning to Reduce High-ISO Noise

MSN, DPReview: Machine learning is often presented as a tool to improve high-ISO. Intel and the University of Illinois Urbana-Champlain are to present their AI algorithm in June:

"The Intel and UIUC team claims the algorithm can now amplify low-light images the equivalent of up to 300 times the exposure, without the same noise and discoloration that programs like Photoshop might introduce or having to take two separate images."



Imaging Resource publishes an interview with Sony managers called "A.I. is the future of mirrorless cameras:"

"That kind of technology is improving very fast. For example, our current processor has some general computing unit, but maybe in the next generation, the general computing CPU should become more designed for AI."

In a half-year old video, Sony Teruo Hirayama and Sony’s strategic advisor also the director of the MIT Media Lab, Joichi Ito discuss how image sensors and AI will combine to enhance human capabilities and open up new possibilities in the future:

Imec and Holst Centre Unveil Organic Fingerprint Sensor

Imec: Holst Centre, a joint initiative of imec and TNO, have demonstrated a new class of flexible, large-area sensor technology for detecting finger- and palmprints. At less than 0.2 mm thick, the new sensors can be embedded into objects such as mobile phones and door handles to create “invisible” yet secure access control systems that can tell if the print is from a living person rather than a phantom or counterfeit.

Two demonstrators are shown: Measuring 6 x 8 cm, a 200-ppi demonstrator is large enough for 4-finger scanners that are currently used by border control authorities and delivers sufficient image quality for basic identification applications. Meanwhile, a slightly smaller 500-ppi demonstrator offer even higher image quality, compatible with FBI standards and enough for law enforcement agencies to visualize minutia and pores for more robust identification.

As with Holst Centre’s earlier flexible X-ray detectors, the fingerprint sensors combine an organic PD frontplane, an oxide TFT backplane, and a thin-film barrier for protection against the environment. All three technological elements have been or are being transferred to industry for scale-up and commercialization. The sensors read the finger- or palm print by detecting visible light (400 to 700 nm) reflected from the surface of the skin. However, they can also detect light that penetrates someway into the skin before being reflected. This allows them to sense a heartbeat from changes in the capillaries within the hand, and thus verify that the print comes from a live person.

By using different PD materials, the sensors’ band can be extended to other wavelengths such as NIR. This could enable new identification verification modes based on, for example, the pattern of veins in a hand, which is believed to be even more specific to an individual than a fingerprint.

“The flexible fingerprint sensor demonstrator shows the versatility and maturity of the flexible electronics technologies that Holst Centre is developing. With the underlying technology already in use in the flat-panel industry, there is a fast route to manufacturing and we are looking for industrial partners to take that step,” says Hylke Akkerman, Program Manager at Holst Centre.
