Renesas’ New Four-Channel Video Decoder for Automotive Cameras Enables Economical Surround View Applications
  Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the newest device in its Automotive HD Link (AHL) portfolio that enables automotive manufacturers to deliver high-definition video over low-cost cables and connectors. The new RAA279974 4-channel AHL video decoder processes four input sources simultaneously, making it an economical solution for surround-view and multi-camera applications.  Renesas’ AHL technology uses a modulated analog signal to transmit video. The frequency is therefore 10 times lower than digital transmission solutions available in the market today (~37MHz vs. >3GHz), making it robust against noise and enabling longer transmission distances (20-30m) with unshielded twisted pair cables and standard connectors. Existing standard-definition analog video cables and connectors can also be employed. Using unshielded twisted pair cables not only reduces cost, but it is also easier to route through the vehicle and offers lighter weight for improved energy efficiency and performance. Digital links such as SerDes require heavily shielded cables and high-end connectors that cost significantly more than those for AHL and may require replacement after five to seven years.  The RAA279974 completes the AHL family of products which consists of the RAA279971, single channel AHL video encoder and the RAA279972, a single channel AHL video decoder. The RAA279974 is an important addition to the AHL family as most OEMs want to support multiple cameras in vehicles for applications such as surround view parking assistance monitors. AHL can be paired with R-Car Automotive SoCs, RH850 MCUs, automotive PMICs, and analog components to cost-effectively implement numerous safety features in virtually any vehicle. Renesas provides multiple Winning Combinations that combine these components to enable manufacturers to quickly implement pre-tested video designs.  “Multi-camera safety systems are quickly becoming a must-have feature for many consumers,” said Davin Lee, Vice President of the Analog & Connectivity Product Group. “The AHL system enables our automotive customers to now deliver these features in all new vehicles, including economy models.”  AHL is robust against noise and offers excellent picture quality. There is no noticeable difference in picture quality when compared to a pure digital video image. Due to the fundamental nature of an analog signal, an AHL video transmission can withstand noise and interference. The picture may degrade slightly, but there will still be a live image to view. With a digital link, any noise/interference will result in a complete loss of picture.  Key Features of AHL  Supports resolutions from VGA up to 720p/60 or 1080p/30 for flexibility to implement non-standard vertical resolutions (not just the TV video standard 16:9 resolutions)  MIPI-CSI2, BT656, & DVP inputs and outputs provide flexible interface to support a variety of image sensors  AHL does not require compression like an Ethernet system does, so it has no latency in the video  Requires only 27MHz crystal clock, with internal PLLs able to generate the necessary clock frequencies for higher resolutions, reducing cost  AHL has passed BCI & CISPR25 EMC/EMI testing using UTP cables  MIPI-CSI2 output with Virtual Channel allows 4 channels of video to be sent over a single data bus interface to the SoC (saves input ports on the SoC)  Availability  The four-channel RAA279974 AHL decoder samples and evaluation boards are available today. Renesas also offers the RTKA279974ZK0000BU Camera Kit Bundle evaluation system which includes four AHL cameras integrated with the RAA279971 AHL encoder.

Nidec Instruments Develops a New TiltAC, an Image-stabilizing Module for Smartphone Cameras
  Nidec Corporation (TSE: 6594; OTC US: NJDCY) (the “Company”) announced today that Nidec Instruments Corporation (“Nidec Instruments”), a wholly owned subsidiary of the Company, has developed a new TiltAC®, an image-stabilizing module for smartphone cameras.  At present, 1.3 billion smartphones are shipped annually in the world, and almost all of them are equipped with cameras. Since 2019, Nidec Instruments has been supplying to the market TiltAC®, an image-stabilizing module known for preventing image quality deterioration, maximizing lenses and image sensors, and working in conjunction with a gyroscope sensor installed on a smartphone.  Single-lens reflex and other cameras use the OIS (Optical Image Stabilizer), a method to shift a lens or CMOS (Complementary Metal Oxide Semiconductor) and an image sensor in a direction to cancel out their shake and keep the optical axis at the center of the image. Whereas, smartphones in general employ the EIS (Electronic Image Stabilizer), with which deterioration in image quality has been inevitable due to its mechanism of stabilizing a shot image by digitally cutting out part of it.  TiltAC®, which uses Nidec Instruments’ uniquely developed technology, utilizes its entire camera module – including everything from its lens to CMOS sensor – as a movable part to detect angular displacement (velocity) with a gyroscope sensor and control the actuator’s movements in a direction to cancel them out, and keep the camera module facing straight toward the subject. This technology prevents digital processing-caused quality deterioration of peripheral areas’ images, and maximizes the CMOS’s performance, enabling the user to take high-quality still and moving images easily.  With a revised design of its movable sections, this newly developed module enjoys a footprint approximately 11% smaller than that of its existing predecessors, while maintaining their functions and performance. With a growing number of high-end and other smartphone models equipped with multiple cameras in recent years, mobile phone manufacturers had been urging us to miniaturize cameras on their products.  As a member of the world’s leading comprehensive motor manufacturer, we at Nidec Instruments stay committed to proposing revolutionary solutions that contribute to creating a comfortable society to live in.

Shipments of Sensing Camera in Automotive OE Market Will Grow by 63% YoY
According to the latest research by TrendForce, the demand for sensing camera in automotive OE (Original Equipment) market will see considerable growth in 2018, driven by the development of smart vehicles in high-end market and the establishment of regulations in the U.S., the EU, Japan and China. The shipments of sensing camera in automotive OE market are expected to reach 121 million units in 2018, a year-on-year growth of 63% compared with 74 million units in 2017.“The soaring demand for sensing cameras is attributed to the development of autonomous driving”, says Yvette Lin, analyst of TrendForce. Driven by advancements in artificial intelligence, communication and sensing technology, many technology companies and traditional car makers have invested in the R&D of autonomous driving. Consumers also show increasing concerns for active safety, which push the demand for advanced driver assistance system (ADAS) and sensors.Currently, car makers adopt different ADAS sensing solutions, including millimeter-wave radar, ultrasonic radar and automotive camera, etc. Particularly, camera-based solutions are gradually accepted by car manufacturers since breakthroughs have been made in image recognition algorithms and capabilities of image processing chips. Camera-based solutions, which can detect the traffic around vehicles through image recognition, are now applied in both cars with ADAS and autonomous-driving vehicles in testing.According to Lin, current mass produced cars with ADAS carry an average of 4 to 8 cameras per car. After the launch of highly-autonomous vehicle in 2020, the number of cameras embedded in each car will increase to 10 to 12. In this trend, major camera manufacturers across the world have been actively deploying in the automotive market, including Chinese companies Sunny Optical and Sunex, Taiwan-based Asia Optical and Calin, and Korean manufactures Sekonix, who have been shipping products to the first-tier car makers.In addition to the development of smart vehicles in high-end market, the establishment of regulations for vehicle safety in the U.S., the EU, Japan and China also drives the rapid expansion of market. Since 2016, forward collision warning (FCW), lane maintenance system (LDW), automatic emergency braking system (AEB), and blind spot detection system (BSD) have been mandatory for vehicles or included in the New Car Evaluation Standard (NCAP) in areas like the United States, the European Union, and Japan. Particularly, China has for the first time included a number of evaluation criteria for active safety in the 2018 version of NCAP. As the largest market of cars in the world, China witnesses increasing demand for sensing camera, which will boost the global market for automotive sensing camera. TrendForce estimates that the shipments of automotive sensing camera will reach nearly 124 million units by 2020.

China Startup Packs AI in Camera
  An ambitious startup in Beijing has started shipping systems using its own designs for machine-learning SoCs. Horizon Robotics ultimately aims to power millions of cars and smart cameras with its AI chips.  The startup adds fuel to China’s claims that it will take a leading role in machine learning. Horizon’s chief executive sits on the country’s committee driving a national initiative in AI.  Founded in July 2015, Horizon’s top executives come from AI groups at Baidu and Facebook and the chip division of Huawei. They have received more than $100 million in venture funding from more than a dozen investors including Intel Capital, Sequoia Capital, and Sinovation Ventures.  So far, the company has shipped two 40-nm chips with custom blocks to accelerate neural-network inferencing jobs for self-driving cars and smart cameras. It is now working on a 28-nm generation and has plans for 16-nm chips. It also develops its own software and cloud service.  The startup debuted its HR-IPC2143, a high-def security camera using its Sunrise SoC at last week’s International Security Technology Show in Las Vegas. The company claims facial recognition accuracy up to 99.7% for the chip that sports a 50,000-feature library and processes 1,920 x 1,080-progressive video at 30 frames/second while consuming 1.5 W.  “We designed our own chip because it runs our AI algorithm more efficiently,” said Kai Yu, chief executive and founder of the startup, in an email exchange “Existing chips are not powerful or efficient enough to satisfy AI tasks on the edge.”  The chip accelerates inference jobs on a variety of neural networks such as ResNet, MobileNet v1 and v2, and Xception by breaking them down into smaller tasks handled by its unique instruction set, said Kai Yu. Before the startup, he founded Baidu’s Institute of Deep Learning in January 2013, which claims that it was the first AI lab in China. He also started Baidu’s autonomous driving project.  Initially, Horizon is taking on the job of training its own neural nets. Its co-founders include a former chief architect at Baidu, Chang Huang, and a founding member of Facebook’s AI research team, Ming Yang.  “Our goal is that by 2020, our chips could enable hundreds of millions of smart devices,” said Kai Yu.  The 28-nm follow-on to the Sunrise chip aims to run at less than a watt and support up to four cameras, sensor fusion, and sparse and binary networks. Its 16-nm successor will handle 4K video and up to 8 cameras. It will also support recurrent and other neural net types while keeping power below 2 W.  A separate 40-nm Journey SoC now shipping uses a similar machine-learning architecture but is tailored for level-two advanced driver assistance systems. The startup’s chip design operations are run by Feng Zhou, a former principal IC architect at Huawei and a professor at Zhejiang University.

Vision Show: Lights, Cameras, Automation
  The Vision Show took place this week. It was, you might say, rather "visual" with all those colorful LEDs and lasers, plus lots of motion and cameras to catch it all.  The exhibit hall at the Hynes Convention Center was roughly divided into components — lighting, embedded computers, cameras, and frame grabbers — and systems for visual inspection and automation. There's nothing dull here, what with all the colorful lights and motion. Here's some of what we saw.  Advanced Illumination, a company with a long history of LED lighting, had enough LEDs to light up the entire hall. As bright as they looked, the lights were turned down quite low to keep from blinding those who passed by.  The lights were bright at The Vision Show 2018. Photo by Martin Rowe.  Technical Sales and Product Specialist Daryl Martin explained how the LEDs are configured and driven. In most cases, the LED arrays consist of parallel-serial circuits driven by current sources. Typically, each serial string consists of six LEDs. Then the strings are connected in parallel, all powered by a current source. But each string will develop a unique forward voltage. "How do you compensate for those differences?" I asked. Martin wouldn't say exactly how that's done other than to say that the best way is to have a separate current source for each six-LED serial string. A circuit such as the one in LED strings driven by current source/mirror shows a simple circuit that compensates for those differences in forward voltage.  U.K.-based Gardasoft Vison manufactures controllers that drive LEDs with current. The company demonstrated a vision system in which some cereal boxes were illuminated by LEDs driven by the company's controllers.  In addition to LEDs for lighting, The Vision Show also had exhibits of lasers in assorted colors such as these from New Hampshire-based Laser Components.  Lasers from Laser Components. Photo by Martin Rowe.  Sometimes you need LEDs to illuminate large areas, or you need backlighting for signs. This 5-second video shows LED backlighting from TPL Vision that looked even brighter in person, but it's plenty bright here.  Industrial cameras are the front end of any machine vision system. Connected to desktop, laptop, or embedded computers, cameras capture video where software is then used to look for specific characteristics in an image such as barcodes. But systems can identify almost anything. You can see that in action on some system videos on the next page. Here's a sampling of some of the equipment on display in Boston.  ixCameras manufactures high-speed, high-resolution cameras. Camera control can be from a PC or tablet. The company's latest 7-Series cameras have CCD sensors capable of 2,048 x 1,536-pixel images.  An iSPEED 7-Series camera from ixCameras of Woburn, Massachusetts. Photo by Martin Rowe.  Back-Bone's Ribcage H6PRO camera is attached to a lens and provides connectivity to a computer or tablet, producing mp4 video through a USB-C cable. In the photo below, the camera is attached to a telephoto lens, but the company also exhibited a fish-eye lens.  Cameras from Back Bone attach to lenses and provide a link to a PC. Photo by Martin Rowe.  Neosys Technology was one of several Taiwanese companies exhibiting embedded computers. Machine-vision systems often use these industrial computers for image processing and mechanical control.  Lucid Vision Labs of Richmond, BC, used flowers to show off its latest Phoenix series of GigE cameras. The image below shows the system and flowers above a photo of a monitor screen containing an image of the flowers.  Camera maker Imaging Development Systems (IDS) uses a mechanical "bug" in a tube to demonstrate its cameras and software. In the 1-min. video below, you can follow it through the tube and see it on a monitor screen. IDS cameras use GigE and USB interfaces to transfer video.

Single-Pixel Camera Mimics Human Eye
  The smart single-pixel camera mimics the human eye by focusing on the important details in images, such as faces, and allotting lower-resolution to areas of unimportance such as backgrounds. The invention made by researchers at the University of Glasgow (Scotland, U.K.) appears in Science Advances titled Adaptive foveated single-pixel imaging with dynamic supersampling.  The University of Glasgow has been experimenting with scanning cameras that use a single pixel because of their low cost and the fact that they can more easily target parts of the electromagnetic spectrum inaccessible to megapixel imager chips, namely terahertz and far infrared. But now with the capability of capturing more detail where it counts and fuzzing out areas of little importance, the single-pixel camera should be much more useful to researchers and even lower in cost than before.  Dumb uniform resolution of pixels leaves a blurry image unless the entire picture is sampled at high-resolution (left) whereas smart spatial resolution (right) in the single-pixel camera allots higher resolution where there are details and falls back to low-resolution where there are no details, thus taking faster shots with less energy expended.  For their recent experiments, researchers used their single-pixel to scan a 1,000-by-1,000 pixel area, which by modern standard is very low resolution (just 1-Mbyte). However, since the camera picks out the important parts, scanning them at much higher resolution, its performance matched that of a multi-mega-pixel camera.  The invention team leader was professor David Phillips at the Royal Academy of Engineering Research, a Fellow at the University of Glasgow’s School of Physics and Astronomy. He is now exploring opportunities for industrial and commercial use. His team was building on the prior work of professor Miles Padgett, whose focus was on 3D photos, imaging gas leaks, and penetrating opaque surfaces with optics.  Get all the details in Adaptive foveated single-pixel imaging with dynamic supersampling".  Funding was provided by the Engineering and Physical Sciences Research Council (EPSRC) and the Royal Academy of Engineering (RAEng) in the U.K.
