Automotive News from Autosens Brussels

Image Sensors World        Go to the original article...

EETimes reporter Junko Yoshida publishes "ADAS: Key Trends on ‘Perception’" from Autosens Brussels held in mid-September 2019:
  • At this year’s AutoSens in Brussels, assisted driving (ADAS), rather than autonomous vehicles (AV), was in sharper focus. Clearly the engineering community is no longer in denial. Many acknowledge that a big gap exists between what’s possible today and the eventual launch of commercial artificial intelligence-driven autonomous vehicles.
  • Many vendors are adding more intelligence at the sensory node, by fusing different sensory data (RGB camera + NIR; RGB + SWIR; RGB + lidar; RGB + radar) right on the edge.
  • Trieye claims it has found a way to design SWIR by using CMOS process technology. “That’s the breakthrough we made. Just like semiconductors, we are using CMOS for the high-volume manufacturing of SWIR cameras from Day 1,” said Avi Bakal, CEO and co-founder of Trieye.
  • EE Times’ subsequent discussion with Trieye revealed that Outsight will be using Trieye’s SWIR camera. Outsight is promoting its sensor fusion box, scheduled for sampling in the first quarter of 2020.
  • AEye is finishing the combined RGB and lidar system, automotive grade, embedded with AI in the next three to six months. The price will be “less than $1,000.”

ISP Optimization for Automotive Applications

Image Sensors World        Go to the original article...

MDPI publishes Valeo paper "Overview and Empirical Analysis of ISP Parameter Tuning for Visual Perception in Autonomous Driving" by Lucie Yahiaoui, Jonathan Horgan, Brian Deegan, Senthil Yogamani, Ciarán Hughes, and Patrick Denny.

"Image quality is a well understood concept for human viewing applications, particularly in the multimedia space, but increasingly in an automotive context as well. The rise in prominence of autonomous driving and computer vision brings to the fore research in the area of the impact of image quality in camera perception for tasks such as recognition, localization and reconstruction. While the definition of “image quality” for computer vision may be ill-defined, what is clear is that the configuration of the image signal processing pipeline is the key factor in controlling the image quality for computer vision. This paper is partly review and partly positional with demonstration of several preliminary results promising for future research. As such, we give an overview of what is an Image Signal Processor (ISP) pipeline, describe some typical automotive computer vision problems, and give a brief introduction to the impact of image signal processing parameters on the performance of computer vision, via some empirical results. This paper provides a discussion on the merits of automatically tuning the ISP parameters using computer vision performance indicators as a cost metric, and thus bypassing the need to explicitly define what “image quality” means for computer vision."


Alexis Lluis Gomez, Senior Manager of Image Quality, ARM, talks about automotive ISP optimization too in his Autosens Detroit presentation:



Manjunath Somayaji, Director of Imaging R&D, GEO Semiconductor, presents its view on ISP optimization:



On its side, Algolux says that ISP should be tightly integrated into the whole CV pipeline, rather than optimized as a separate block:

TechInsights publishes a teardown report of the new Apple iPhone 11 Pro Max smartphone with some info on its cameras:

"We were excited during the September Apple Special Event to hear of 100% Focus Pixels for iPhone’s wide-angle camera. We expected this to coincide with full-chip dual photodiode phase detection autofocus (PDAF), however our initial findings show a familiar PDAF pattern comparable to that used for 2018 iPhone’s wide-angle camera. The analysis in progress will determine if Apple has indeed gone to dual PD as 100% Focus Pixels suggests. If true, it would be the first use of masked + dual PD PDAF we have documented."

MIPI Alliance Announces CSI‑2 v3.0, C-PHY v2.0, and D-PHY v2.5

Image Sensors World        Go to the original article...

BusinessWire: MIPI Alliance announces enhancements to MIPI Camera Serial Interface-2 (MIPI CSI‑2), the most widely used camera specification in mobile and other markets.

MIPI CSI‑2 v3.0 introduces three key new features:
  • Unified Serial Link (USL), for encapsulating connections between an image sensor module and application processor—This capability is crucial for reducing the number of wires needed in IoT, automotive and client products for productivity and content creation, such as all-in-one and notebook computers.
  • Smart Region of Interest (SROI), for analyzing images, inferencing algorithms and making better deductions—This capability could enable machines on a factory floor, for example, to more quickly identify potential defects on a conveyor belt, or it could enable medical devices to more surely recognize anomalies such as tumors.
  • RAW-24, for representing individual image pixels with 24-bit precision—This capability will enable machines to make decisions from superior quality images. An autonomous vehicle, for example, could decipher whether darkness on an image is a harmless shadow or a pothole in the roadway to be avoided.

Innovation of MIPI CSI‑2 never stops; we aim to remain at the frontier of providing end-to-end imaging conduit solutions for emerging vision and real-time perception and decision making AI applications mapped to mobile, client, IoT, medical, drones and automotive (ADAS) product platforms,” said Haran Thanigasalam, MIPI Camera Working Group chair. “In fact, work is already well underway on the next version of MIPI CSI‑2, with a highly optimized ultra-low-power always-on sentinel conduit solution for enhanced machine awareness, data protection provisions for security, and functional safety, as well as MIPI A-PHY, a forthcoming longer reach physical layer specification.

MIPI C-PHY v2.0 was recently released to support CSI‑2 v3.0 capabilities, including support for 6 Gsps over the standard channel and up to 8 Gsps over the short channel; RX equalization; fast BTA; medium channel lengths for IoT applications; and an in-band control signaling option. MIPI D-PHY v2.5, with alternate low power (ALP), which uses pure low-voltage signaling instead of legacy 1.2 V LP signaling and a fast BTA feature for support of CSI‑2 v3.0, will be released later this year.

ams Launches Extended Range dToF Module

Image Sensors World        Go to the original article...

Businesswire: ams announces the world’s smallest integrated module for direct ToF distance measurement in range from 2cm up to 2.5m. The TMF8801 is said to be more than 30% smaller than competing ToF sensors yet offers good accuracy and usability in the presence of sunlight. Competing ToF sensors struggle to accurately measure distance below dirty or smudged cover glass whereas the TMF8801 maintains high accuracy through use of its on-chip histogram processing.

The new TMF8801 direct ToF sensor which complements the TMF8701 short range ToF sensor released in 2018, provides extended distance range sensing for smartphones,” says Dave Moon, Senior Product Marketing Manager in the Integrated Optical Sensors business line at ams. “The TMF8801 is ideally suited to provide support for improving world-facing mobile phone camera performance using laser detection auto-focus (LDAF), enabling mobile phone users to take pin-sharp photos and selfies.

With an integrated 940nm VCSEL, multiple SPADs, time-to-digital converter, and on-chip microcontroller for processing histograms, the TMF8801 delivers superior ToF performance. Compared to distance averaging employed with an indirect ToF system, the direct ToF time measurement methodology used in the TMF8801 is said to deliver higher accuracy distance measurements. When used to support LDAF, high accuracy distance measurements deliver improved camera performance.

The small size and low power consumption of the TMF8801 is suitable for collision avoidance detection used in autonomous vacuum cleaners, and industrial robotics. For display-based products such as mobile computing, the TMF8801 can be used for user presence detection to automatically wake up or put the system into a low-power sleep mode based on the presence or absence of a user.

The TMF8801 is housed in a 2.2mm x 3.6mm x 1.0mm package and is in volume production. Unit pricing is $2.89 in order quantities of 5,000 pieces.


The previous generation TMF8701 sensor has a shorter range up to 60cm in a similarly sized package. It has won an number of awards.

Prophesee Introduces Event-Based Sensor in Industry-Standard, Cost-Efficient Package

Image Sensors World        Go to the original article...

PRNewswire, EETimes: Prophesee introduces what it calls the first industry-standard packaged chip with Event-Based Vision technology, a significant advancement over traditional frame-based vision approaches.

Under development for five years and commercially tested, this third-generation version is a VGA sensor with 15 μm pixels in a 3/4" optical format. It is aimed at developers of cameras in industrial automation and IoT systems such as robots, inspection equipment, monitoring and surveillance devices. It leverages Prophesee's neuromorphic vision technology to offer efficient capabilities for a variety of use models, including ultra high-speed part counting, vibration measurement and monitoring or kinematic monitoring for predictive maintenance.

"This is a major milestone for Prophesee and underscores the progress in commercializing our pioneering Event-Based Vision sensing technology. After several years of testing and prototyping, we can now offer product developers an off-the-shelf means to take advantage of the benefits of our machine vision inventions that move the industry out of the traditional frame-based paradigm for image capture," said Luca Verre, co-founder and CEO of Prophesee.

In Prophesee Metavision sensor, each pixel is independent and asynchronous, only activating if it senses a change in the scene, a movement - an event. This proprietary Event-Based approach allows for major reductions of power, latency and data processing requirements imposed by traditional frame-based systems. It enables sensors to achieve much higher DR than commonly associated with high-speed vision. And it allows cost-efficient sensors and systems to record events that would otherwise require conventional cameras to run at 10,000 fps.

The chip is packaged in a 13x15 mm mini PBGA package and is manufactured in a 0.18um CIS process. The packaging was realized by Kingpak.

ON Semi-Rochester Stops Making CCDs

Image Sensors World        Go to the original article...

ON Semi announces that it discontinues all its CCD products (also here.) The rumor says that the last reminder about Kodak image sensor business, the Rochester, NY, CCD fab will be closed on June 20, 2020 (confirmed from 3 independent sources.)

"The ongoing market conversion from CCD to CMOS image sensors has been accelerated both by an industry slowdown that began in 2018 as well as availability of advanced CMOS image sensors such as ON Semiconductor’s line of XGS products. In light of these factors, ON Semiconductor has been monitoring the sales activity and viability of our CCD image sensor products. The recent activity for the products on the attached device list has declined to a level which can no longer be sustained. As a result of this analysis we regret to announce discontinuance of our CCD products as described in this notification.

All CCD products are impacted by this change. The list of OPNs provided with this notification includes suggested replacement parts (where it was possible to identify a suitable replacement). In many cases, a call to ON Semiconductor Sales may be appropriate to discuss XGS CMOS image sensors in detail. For those devices that have no recommended replacement identified, ON Semiconductor has partnered with Rochester Electronics who will carry any remaining device inventory to potentially allow for a continued source after ON Semiconductor has completed its business process.

PLEASE NOTE: ON Semiconductor may implement minimum order quantities or dollar amounts based on inventories available. Also, Devices on this Product Discontinuance become NCNR (Non-Cancelable, Non-Returnable).

SiOnyx vs Hamamatsu Patent Litigation Wrap-Up

Image Sensors World        Go to the original article...

Fish and Richardson Litigation Blog publishes a summary of SiOnyx vs Hamamatsu Photonics (HPK) patent lawsuit:

"At trial, the jury found that the HPK willfully infringed SiOnyx’s U.S. Patent No. 8,080,467. The jury also found that HPK breached a non-disclosure agreement it had with SiOnyx, because “HPK took [SiOnyx’s] inventive ideas, added other inventive ideas to it, and obtained [nine] patents as a result.”

The jury awarded SiOnyx $796,469 in damages for breach of contract and $580,640 in damages for unjust enrichment. But, despite finding willful patent infringement, the jury awarded $0 in damages for patent infringement.

SiOnyx moved for “an injunction awarding [it] ownership of [HPK’s nine] patents….” The Court considered the jury’s finding that “HPK [] took confidential information SiOnyx had entrusted to it and used it for its own gain [by filing nine patents].” ....The Court thus granted an affirmative injunction “awarding and transferring ownership of [HPK’s nine] patents to SiOnyx[].”

The Court explained that “SiOnyx is a tiny company relying on a single type of technology, whereas HPK is a large company with a broad and diversified range of products.” Thus, the Court granted an injunction prohibiting HPK from “making, using, offering for sale, selling, or importing products infringing [SiOnyx’s] ’467 patent.”

HPK appealed this case to the Federal Circuit in late August, and that appeal is pending.

Samsung Unveils Industry’s First 0.7um Pixel

Image Sensors World        Go to the original article...

BusinessWire: Samsung introduces the industry’s first 0.7μm pixel sensor, the 43.7MP ISOCELL Slim GH1.

Samsung has been stepping up in pixel technology innovation from the industry’s first 1.0μm-pixel image sensor, to most recently, 0.8μm ultra-high-resolution sensors at 64Mp and 108Mp,” said Yongin Park, EVP of the sensor business at Samsung Electronics. “We are pleased to deliver yet another breakthrough with the industry’s first 0.7μm pixel image sensor, the ISOCELL Slim GH1 that will enable sleeker and more streamlined designs as well as excellent imaging experiences in tomorrow’s smartphones.

ISOCELL Plus, Samsung’s latest pixel isolation technology, minimizes color cross-talk and optical loss in the 0.7μm pixel. In low-light environments, the GH1 makes use of pixel-merging Tetracell technology that enables higher light sensitivity equivalent to that of a 1.4μm-pixel image sensor.

For video recording at 4K (3,840×2,160) resolutions, the ISOCELL Slim GH1, with a high resolution of 7,968×5,480, is able to take 4K videos with minimum loss in FoV, while most high-resolution image sensors crop or scale down full image resolutions that result in a reduced FoV. Using Tetracell technology, the GH1 is converted down to 3,984×2,740 at 60fps.

GH1 supports a gyro-based EIS, a phase detection AF, and a real-time HDR. The ISOCELL Slim GH1 is expected to be in mass production by the end of this year.
