Brillnics Presents its First Products

Japan and Taiwan-based startup Brillnics unveils its first products for security and surveillance applications: two new 1/2.7” 1080p color BSI CMOS sensors: BRV0200 (60fps) and BRV0201 (120fps) utilizing Brillnics patented H³DRTM technology.

We see customers expecting high imaging quality under extremely low light for various video applications. Collaborating with strategic foundry partner, Brillnics uses BSI technology featuring high sensitivity, high angular response, and low noise.”, said Dr. Shou-Gwo Wuu, CEO of Brillnics and former TSMC CIS group manager. “We are particularly excited about the introduction of single exposure HDR (SE HDR), which can significantly mitigate motion artifacts caused by moving objects. SE HDR allows the highest video fidelity in fast-moving scenes, such as in automotive applications.

In comparison with most common HDR approaches, including a logarithmic response pixel, a linear-logarithmic response pixel, a dual photodiode pixel, or a multiple exposure HDR (ME HDR) scheme, Brillnics adopts the multiple exposure HDR scheme and/or single exposure HDR scheme. The SE HDR mode obtains two data from a same pixel. One is a lower response and the other a higher response, of which integration times are identical with no timing shift, unlike the ME HDR. Linearization using the two data is then performed on-chip, yielding 16bit digital signal or 12bit compressed digital signal.

The high dynamic range of the BRV0200/0201 in SE HDR mode is made possible by its very high low-light sensitivity and very high full well capacity. The very high low-light sensitivity comes from its high QE and low readout noise floor. Also, the very high full well capacity has been realized in the close collaboration with the strategic foundry partner.

Product Highlights:
  • Process: BSI
  • Pixel Size: 3.0 um
  • Optical Format: 1/2.7”
  • Angular Response: 85% @ ±20°
  • Max Frame Rate: 120fps, 12bit (BRV0201)
  • Hybrid Modes HDR: MEHDR/SEHDR
  • SE HDR: Dual conversion gain readout in single exposure time
  • SE HDR >85dB and ME HDR 120dB
  • SNRmax: 44dB
  • Power consumption: typ. 178mW at 60fps, 12bit

Waymo Accuses Uber-acquired Otto in Stealing LiDAR Secrets

Bloomberg: It took Alphabet’s Waymo seven years to design and build a LiDAR for its self-driving cars. Uber-acquired Otto startup allegedly did it in nine months. Waymo claims in a lawsuit that its former employees stole the designs and technology and started a new company. Waymo says:

"One of the most powerful parts of our self-driving technology is our custom-built LiDAR — or “Light Detection and Ranging.” LiDAR is critical to detecting and measuring the shape, speed and movement of objects like cyclists, vehicles and pedestrians.

Hundreds of Waymo engineers have spent thousands of hours, and our company has invested millions of dollars to design a highly specialized and unique LiDAR system. Waymo engineers have driven down the cost of LiDAR dramatically even as we’ve improved the quality and reliability of its performance. The configuration and specifications of our LiDAR sensors are unique to Waymo. Misappropriating this technology is akin to stealing a secret recipe from a beverage company.

In 2016, Uber bought a six-month old startup called Otto and appointed its founder (a former employee on our self-driving car project) as its head of self-driving technology. At the time, it was reported that Otto’s LiDAR sensor was one of the key reasons Uber acquired the company.

Recently, we received an unexpected email. One of our suppliers specializing in LiDAR components sent us an attachment (apparently inadvertently) of machine drawings of what was purported to be Uber’s LiDAR circuit board — except its design bore a striking resemblance to Waymo’s unique LiDAR design.

We found that six weeks before his resignation this former employee, Anthony Levandowski, downloaded over 14,000 highly confidential and proprietary design files for Waymo’s various hardware systems, including designs of Waymo’s LiDAR and circuit board. To gain access to Waymo’s design server, Mr. Levandowski searched for and installed specialized software onto his company-issued laptop. Once inside, he downloaded 9.7 GB of Waymo’s highly confidential files and trade secrets, including blueprints, design files and testing documentation. Then he connected an external drive to the laptop. Mr. Levandowski then wiped and reformatted the laptop in an attempt to erase forensic fingerprints.

Beyond Mr. Levandowki’s actions, we discovered that other former Waymo employees, now at Otto and Uber, downloaded additional highly confidential information pertaining to our custom-built LiDAR including supplier lists, manufacturing details and statements of work with highly technical information.

No Lens is Needed to See Simple Images

University of Utah, Salt Lake City, USA, researches show that the simple 32x32 images can be seen by a bare image sensor with no lens. The open-access paper "Lensless Photography with only an image sensor" by Ganghun Kim, Kyle Isaacson, Racheal Palmer, and Rajesh Menon has been published in arxiv.org. From the abstract:

"Photography usually requires optics in conjunction with a recording device (an image sensor). Eliminating the optics could lead to new form factors for cameras. Here, we report a simple demonstration of imaging using a bare CMOS sensor that utilizes computation. The technique relies on the space variant point-spread functions resulting from the interaction of a point source in the field of view with the image sensor. These space-variant point-spread functions are combined with a reconstruction algorithm in order to image simple objects displayed on a discrete LED array as well as on an LCD screen. We extended the approach to video imaging at the native frame rate of the sensor. Finally, we performed experiments to analyze the parametric impact of the object distance. Improving the sensor designs and reconstruction algorithms can lead to useful cameras without optics."

More about Mobileye 7.4MP Automotive Camera

SeekingAlpha: Mobileye Q4 2016 earnings call transcript has an interesting part about the company's 7.4MP autonomous driving camera platform:

Itay Michaeli - City analyst

...how important is the 2019 launch of the ultra-high resolution camera to automakers to be able to perform those Level 2 plus functions? And then if you could also comment on the hardware cost to the automaker of that camera relative to mono and trifocal today?

Amnon Shashua - CTO & Chairman

So, regarding the ultrahigh-definition camera, this is a 7.4 megapixel camera. 2019, we have programs that have a 1.7 megapixel camera. We have programs that have 2 megapixel cameras. These are parking cameras that are used also for autonomous driving, not only for parking. And we have the 7.4 megapixel, in many cases, it replaces the trifocal. So, we have a single mono camera with 120 degrees field view replacing three cameras. So, this particular camera is going to be more expensive. It’s not the imager that is so much more expensive, it is the lens. Lens is more expensive. So, it’s few – I can’t say exactly how much more expensive, but it is more expensive and this allows – so basically the ultrahigh-definition camera allows to replace the trifocal with a single monocular camera.

Thanks to DS for the link!

Stuttgart University Proposes 3D Printed Microlens

Science Advances: University of Stuttgart, Germany, researchers propose to utilize a femtosecond laser-based 3D printer to print high precision multi-component microlens directly onto CMOS image sensor. Their paper "3D-printed eagle eye: Compound microlens system for foveated imaging" by Simon Thiele, Kathrin Arzenbacher, Timo Gissibl, Harald Giessen, and Alois M. Herkommer presents the new approach:

"We present a highly miniaturized camera, mimicking the natural vision of predators, by 3D-printing different multilens objectives directly onto a complementary metal-oxide semiconductor (CMOS) image sensor. Our system combines four printed doublet lenses with different focal lengths (equivalent to f = 31 to 123 mm for a 35-mm film) in a 2 × 2 arrangement to achieve a full field of view of 70° with an increasing angular resolution of up to 2 cycles/deg field of view in the center of the image. The footprint of the optics on the chip is below 300 um × 300 um, whereas their height is less than 200 um. Because the four lenses are printed in one single step without the necessity for any further assembling or alignment, this approach allows for fast design iterations and can lead to a plethora of different miniaturized multiaperture imaging systems with applications in fields such as endoscopy, optical metrology, optical sensing, surveillance drones, or security."

TetraVue Raises $10M for Automotive LiDAR

MarketWired: South California-based TetraVue closes its Series A funding at $10M, led by Robert Bosch Venture Capital and Nautilus Venture Partners, and joined by Samsung Catalyst Fund as well as Foxconn. The funding will enable TetraVue to bring its Ultra High Definition, Solid State Flash LIDAR to the autonomous car industry, and to be the leader in Vision for Things (VfT).

"TetraVue is unparalleled to any other existing technologies in the three-dimensional Flash LIDAR space," said Luis Llovera, Managing Director of Robert Bosch Venture Capital. "We see its technology as being key to the enhancement and development of the autonomous car industry, which will be the future of transportation as we know it."

TetraVue’s core technology differentiation is their patented “light slicer” technology, which uses time and distance measurements in order to find optical intensities using standard CMOS sensors. The company’s approach yields many benefits including higher reliability to meet automotive requirements, low latency, and ability to produce ultra-high resolution images for a wider range of distances at a lower cost.

TetraVue’s technology results in 2 million or more simultaneous distance measurements of ranges—greater than 200 meters in any weather conditions and utilizes orders of magnitude less power than competitors. This performance is optimal for the autonomous car industry, and TetraVue plans to miniaturize and commercialize its fully functioning prototype.

ST Announces 3rd Generation ToF Sensor

ST releases its third-generation laser-ranging sensor based on its SPAD FlightSense technology. The new VL53L1 sensor adds for the first time, optical lenses to the module. This combination boosts core performance while introducing many new features including multi-target detection, cover-glass crosstalk immunity at long distance, and programmable multi-zone scanning. With a form factor of 4.9 x 2.5 x 1.56mm, the sensor module integrates a new lens system, a 940nm VCSEL light source, a processing core, and a SPAD photon detector.

The VL53L1 performs a full measurement operation in as little as 5ms, twice as fast as the earlier-generation devices, for high speed AF operation. It also has doubled the maximum ranging distance of ST ToF sensors to beyond 4.5 meters, ensuring it is well matched to the hyper-focal distance of widely used 21MP camera optics.

The new architecture can detect multiple targets within the scene and also allows manufacturers to sub-divide the SPAD sensing matrix into custom-defined zones. These small zones can then provide spatial ranging information that the customer application can use for dual-camera computation in stereoscopy as well as simple depth-map use cases.

The VL53L1 is in production now.

ST has already shipped hundreds of millions of Time-of-Flight sensors, which have been designed by OEMs into over 70 smartphone models as well as many other consumer devices,” said Eric Aussedat, General Manager of ST’s Imaging Division. “The third-generation FlightSense product uses its improved performance to support new applications, including human-presence detection, while continuing to improve sensor performance for existing use cases.

Global and China Imaging Industry Report, 2016-2020

ResearchInChina publishes "Global and China CMOS Camera System Industry Report, 2016-2020." Few quotes:

"In 2016, the CIS (CMOS Image Sensor) market size approximated USD10.516 billion, rising by 5.6% from a year ago, but with an obvious fall in the speed of growth compared with the growth rate of 13.5% in 2015, mainly because medium- and high-end products are monopolized by Sony and the manufacturers in low- and medium-end fields are hard to break through the technological barriers and do nothing but hit the price war even in the vehicle field.

Although influenced by factors like the Earthquake and the Appreciation of Japanese Yen, Sony still monopolized the medium- and high-end fields by dint of its overwhelming performance superiority and saw an upsurge of 32.9% in its revenue in 2016; by contrast, other players excluding Panasonic and Hynix saw decline. It is expected that, in 2017, the CIS market will grow 4.0%, Sony will see a growth rate of at least 10%, and most others will continue to suffer losses. In spite of being not much expected, the mobile phone market is still the most important market and Sony still monopolizes the high-end mobile phone market.

In 2015, the global CCM (CMOS Camera Module) market size reported USD16.611 billion, up 3.8% from a year earlier but the lowest growth rate since 2010. In 2016, as the shipment of Apple phones with the highest single price of CCM fell, the world CCM market was at low ebb and down 0.5%. Due to the dual-camera stimulus in 2017, the global market rebounds substantially with the growth rate of 4.3% and the size estimated to be USD17.232 billion in 2017 and USD18.512 billion in 2020.

In 2016, Chinese manufacturers made remarkable achievements, while South Korean counterparts saw a drop or slight rise in revenue due to their heavy reliance on Apple and Samsung. Among Chinese players, Q-Tech enjoys the highest growth rate up to 84.5%, followed by Truly, both of which benefited from the outstanding performance of big customers OPPO and VIVO.

It is anticipated that monochrome dual-camera with same pixel will be the mainstream for smart phone brands except Apple in the future, as it is more affordable and can improve nightscape significantly (visible effect betterment for consumers), while Apple will persist in duel-camera design enriching depth of focus. Smart phones tend to be highly homogenized. Although they are still not quite satisfied with the dual-cameras, consumers are more impressed with dual-cameras than mono-camera. So, dual-camera is expected to be a standard configuration in high-end smart phones, and the penetration rate till 2020 would be as high up to 30-40%.
