ST ALS Senses Light Flicker

Image Sensors World        Go to the original article...

GlobeNewswire: STM releases a multispectral ambient light sensor (ALS) that simultaneously provides scene color temperature, ultra-violet (UVA) radiation level, and lighting frequency information. The new VD6281 helps the camera to set appropriate exposure times to avoid flicker artefacts and eliminate banding in pictures and videos, especially in scenes lit with contemporary LED sources.

"Leveraging the Company's extensive camera system know-how, ST's new VD6281 offers customers a state-of-the-art multispectral ambient light sensor," said Eric Aussedat, GM of ST's Imaging Division. "Our roadmap for ALS and flicker sensors is an ideal complement to ST's market-leading FlightSense Time-of-Flight (ToF) product portfolio. With a growing number of high-quality, high-resolution cameras per phone, our goal is to offer an advanced solution to assist white-balance correction and remove flicker artefacts in smartphone camera images. Mobiles equipped with VD6281 were already released in 2018, and many others will be coming soon."

With its form factor of 1.83 x 1.0 x 0.55mm, the VD6281 is said to be the smallest multispectral ambient light sensor available, allowing integration in bezel-free smartphones with small notches and inside smartwatches, where a high screen ratio is at a premium. The sensor uses direct-deposition interferometric filters to create 6 independent color channels: Red, Green, Blue, NIR, UVA and Clear for color-sensing capability and CCT (Color-Correlated Temperature) over a wide field-of-view of 120 degrees. The VD6281 is in production and available now.

Himax updates on its imaging business:

"On CMOS image sensor business updates, we continue to make great progress with our machine-vision sensor product lines. Combining Himax’s industry leading super low power CIS and ASIC designs with Emza’s unique AI-based, ultra-low power computer vision algorithm, we are uniquely positioned to provide ultra-low power, smart imaging sensing total solutions. We are pleased with the status of engagement with leading players in areas such as connected home, smart building and security, all of which new frontiers for Himax.

For traditional human vision segments, we see strong demands in laptop and increasing shipment for multimedia applications such as car recorders, surveillance, drones, home appliances, and consumer electronics, among others.


3D Sensing Business

We have participated in most of the smartphone OEMs’ ongoing 3D sensing projects covering all three types of technologies, namely structured light, active stereo camera (ASC) and time-of-flight. Depending on the customers’ needs, we provide 3D sensing total solution or just the projector module or optics inside the module. We have highlighted in the last earnings call that the 3D sensing adoption for Android smartphone market remains low. The adoption is hindered primarily by the prevailing high hardware cost of 3D sensing and the long development lead time required to integrate it into the smartphone. Instead of 3D sensing, most of the Android phone makers have chosen the lower cost fingerprint technology which can achieve similar phone unlock and online payment functions with somewhat compromised user experience.

Reacting to their lukewarm response, we are working on the next generation 3D sensing with our platform partners aiming to leapfrog the market by providing high performance, easy to adopt and yet cost friendly total solutions, targeting the majority of Android smartphone players. We have a solid product roadmap and plan including new architecture, new algorithm to make it happen. The development progress is on track and the new solution is aiming for smartphone customers’ 2020 models.

We believe that 3D sensing will be widely used by more Android smartphone makers when more killer applications become available and the ecosystem is able to substantially lower the cost of adoption while offering easy-to use, fully-integrated total solutions, for which Himax is playing a key part.

I have mentioned previously that 3D sensing can have a wide range of applications beyond smartphone. We have started to explore business opportunities in various industries by leveraging our SLiMTM 3D sensing total solution. Such industries are typically less sensitive to cost and always require a total solution. We are collaborating with Kneron, an industry leader in edge-based artificial intelligence in which we have made an equity investment, to develop an AI-enabled 3D sensing solution targeting security and surveillance markets. We are also working with partners/customers on new applications covering home appliances and industrial manufacturing.

AIStorm Patent Application

Image Sensors World        Go to the original article...

AIStorm sent me a nice summary of its recent press announcements:

AIStorm addresses the enormous opportunity of enabling more 'intelligence' right at the edge of the network.

1. Company and team
  • This low-profile AI tech startup is poised to tackle a big problem: enabling faster processing of complex AI problems at the very edge of the network — within sensors.
  • AIStorm has developed and patented a new approach that will disrupt the GPU-based approach that is typically used today.
  • Founded/led by David Schie, an expert in analog and mixed-signal hardware design who has led large teams at Maxim, Micrel, and Semtech.
  • The team also includes proven veterans that round out the company's design and fabrication expertise.

2. Market & technology
  • AIStorm has solved a growing problem: the need to process sensor information at the edge of the network to reduce the cost and security risk of transmitting large amounts of raw data.
  • AI systems require information be available in digital form before they can process data, but sensor data is generally analog. AIStorm solves this problem by processing sensor data directly in its native analog form, in real time.
  • AIStorm is targeting some of the world’s largest handset, machine vision, wearable, IoT, automotive, food service, AI assistant, security, biometric device, & imager applications.
  • Gryfalcon, Mythic-AI, Syntiant and Google have all announced they are pursuing AI engine platforms at the edge. But... none of their approaches incorporate sensors into the solution. AIStorm changes that.

3. Investors
AIStorm is backed by four large sensor and industrial companies that are eager to integrate AIStorm's technology into upcoming products…
  • Egis Technology, a major biometrics supplier to handsets, gaming, and advanced driver-assistance systems.
  • TowerJazz, the global specialty foundry leader that specializes in image sensors for commercial, industrial, AR, and medical markets.
  • Meyer Corporation, a world leader in food preparation equipment.
  • Linear Dimensions Semiconductor, a leader in biometric authentication and digital health products.

David Schie's US patent application 20140344200 "Low power integrated analog mathematical engine" shows a convolution engine based on partial charging of caps by the controlled current sources, said to eliminate the need in capacitor scaling to change coefficients:

"The switched capacitor charge controls allow for nodal control of charge transfer based switched capacitor circuits. The method reduces reliance on passive component programmable arrays to produce programmable switched capacitor circuit coefficients. The switched capacitor circuits are dynamically scaled without having to rely on unit passives, such as unit capacitors, and the complexities of switching these capacitors into and out of circuit. The current, and thus the charge transferred is controlled at a nodal level, and the current rather than the capacitors are scaled providing a more accurate result in addition to saving silicon area. Furthermore, the weightings and biases now set as currents may be saved and recalled by coupling current source bias circuits to non-volatile memory means such as analog non-volatile memory."

MIT Sub-THz Imager

Image Sensors World        Go to the original article...

MIT researchers have developed a sub-terahertz-radiation receiving system that could help driverless cars see through fog and dust clouds.

In a paper published online on Feb. 8 by the IEEE JSSC, the researchers describe a two-dimensional, sub-terahertz receiving array on a chip that’s orders of magnitude more sensitive. To achieve this, they implemented a scheme of independent signal-mixing pixels — called “heterodyne detectors” — that are usually very difficult to densely integrate into chips. The researchers drastically shrank the size of the heterodyne detectors so that many of them can fit into a chip. The trick was to create a compact, multipurpose component that can simultaneously down-mix input signals, synchronize the pixel array, and produce strong output baseband signals.

The researchers built a prototype, which has a 32-pixel array integrated on a 1.2-square-millimeter device. The pixels are approximately 4,300 times more sensitive than the pixels in today’s best on-chip sub-terahertz array sensors. With a little more development, the chip could potentially be used in driverless cars and autonomous robots.

A big motivation for this work is having better ‘electric eyes’ for autonomous vehicles and drones,” says co-author Ruonan Han, an associate professor of electrical engineering and computer science, and director of the Terahertz Integrated Electronics Group in the MIT Microsystems Technology Laboratories (MTL). “Our low-cost, on-chip sub-terahertz sensors will play a complementary role to LiDAR for when the environment is rough.

Joining Han on the paper are first author Zhi Hu and co-author Cheng Wang, both PhD students in Han’s research group.

AIStorm Raises $13.2M to Develop AI-on-Sensor Technology

Image Sensors World        Go to the original article...

BusinessWire: San Jose, CA-based startup AIStorm raises $13.2M in Series A round from Egis Technology, TowerJazz, Meyer Corpo, and Linear Dimensions Semiconductor Inc.

This investment will help us accelerate our engineering & go-to-market efforts to bring a new type of machine learning to the edge. AIStorm’s revolutionary approach allows implementation of edge solutions in lower-cost analog technologies. The result is a cost savings of five to ten times compared to GPUs — without any compromise in performance,” said David Schie, CEO of AIStorm.

Using sensor data directly—without digitization is said to enable real-time processing at the edge. AI systems require information be available in digital form before they can process data, but sensor data is analog. Processing this digital information requires advanced and costly GPUs that are not suitable for mobile devices: they require continuous digitization of input data, which consumes significant power and introduces unavoidable digitization delay (latency). AIStorm aims to solve these problems by processing sensor data directly in its native analog form, in real time.

It makes sense to combine the AI processing with the imager and skip the costly digitization process. For our customers, this will open up new possibilities in smart, event-driven operation and high-speed processing at the edge,” said Avi Strum, SVP/GM of the sensors business unit of TowerJazz.

The reaction time saved by AIStorm’s approach can mean the difference between an advanced driver-assistance system detecting an object and safely stopping versus a lethal collision,” said Russell Ellwanger, CEO of TowerJazz.

Edge applications must process huge amounts of data generated by sensors. Digitizing that data takes time, which means that these applications don’t have time to intelligently select data from the sensor data stream, and instead have to collect volumes of data and process it later. For the first time, AIStorm’s approach allows us to intelligently prune data from the sensor stream in real time and keep up with the massive sensor input tasks,” said Todd Lin, COO of Egis Technology Inc.

AIStorm’s management includes CEO David Schie, a former senior executive at Maxim, Micrel and Semtech; CFO Robert Barker, formerly with Micrel and WSI; Andreas Sibrai, formerly with Maxim and Toshiba; and Cesar Matias, founder of ARM’s Budapest design center. AIStorm is based in San Jose, CA with offices in Austria, Taiwan, Phoenix and soon Dresden and Israel.

Electronic Design publishes an interview with Leo Bai, SmartSens’ AI BU General Manager. Few quotes:

"...single-frame HDR Global Shutter technology is better for image-recognition-based AI applications than conventional CMOS image sensors that use Multiple-Exposure HDR technology. Combined with a DVP/MIPI/LVDS interface, single-frame HDR Global Shutter technology can be adapted to various types of SoC platforms.

...adoption of global-shutter technology is growing rapidly, in comparison to rolling-shutter technology. One of the main reasons is that a global-shutter CMOS image sensor is able to achieve excellent real-time performance without the jelly effect, especially in AI and machine-vision applications. With advanced manufacturing process technology and reduced cost, it’s expected to see increasing market demand for global-shutter CMOS image sensors.

Productive Use of Black Sun Effect

Image Sensors World        Go to the original article...

Finally, somebody found the use for black sun effect in a productive way. MDPI publishes Sungkyunkwan University, Korea paper "Accurate and Cost-Effective Micro Sun Sensor based on CMOS Black Sun Effect" by Rashid Saleem and Sukhan Lee.

"An accurate and cost-effective micro sun sensor based on the extraction of the sun vector using a phenomenon called the “black sun” is presented. Unlike conventional image-based sun sensors where there is difficulty in accurately detecting the sun center, the black sun effect allows the sun center to be accurately extracted even with the sun image appearing irregular and noisy due to glare. This allows the proposed micro sun sensor to achieve high accuracy even when a 1 mm × 1 mm CMOS image sensor with a resolution of 250 × 250 pixels is used."
