Electronic Imaging publishes Samsung paper "A new PDAF correction method of CMOS image sensor with Nonacell and Super PD to improve image quality in binning mode" by Yeongheup Jang, Hyungwook Kim, Kundong Kim, Sungsu Kim, Sungyong Lee, and Joonseo Yim."This paper presents a new PDAF correction method to improve the binning mode image quality in the world’s first 0.8um 108 mega pixel CMOS Image Sensor with Samsung Nonacell and Super PD technology.
The conventional PDAF correction method is based on bad pixel-correction (BPC), replacing AF pixel to adjacent normal pixels. Recently, in order to suppress AF artifact, sensor provide an advanced algorithm that detect the directionality of the image pattern near the PDAF pixel area, and determine which area to be referred for the correction. For example, when the algorithm detects no directionality in the pattern, the PDAF pixel will be replaced by referring to all of the same color-pixels within the kernel of 7x7 or 9x9 pixels. If Slash pattern is detected, PDAF correction will refer to the pixels which are located in only slash direction as shown in Table 2. In spite of the advanced algorithm, the AF artifact still occur because of a higher AF density, directional misrecognition or exceptional case of direction.
In order to overcome the limitation of conventional method, new correction method, named Dilution mode have been introduced. In Dilution mode, a Nonacell, which contains AF pixels, outputs its own seed value to a binning output and deliver AF information by embedded data, which is a PDAF Tail mode."

Modeling of SPADs for LiDAR: Hold-off Time, Afterpulsing, Crosstalk, Pile-up Distortions

Image Sensors World Go to the original article...
Politecnico di Milano publishes a MDPI paper "Statistical Modelling of SPADs for Time-of-Flight LiDAR" by Alfonso Incoronato, Mauro Locatelli, and Franco Zappa."Time-of-Flight (TOF) based Light Detection and Ranging (LiDAR) is a widespread technique for distance measurements in both single-spot depth ranging and 3D mapping. Single Photon Avalanche Diode (SPAD) detectors provide single-photon sensitivity and allow in-pixel integration of a Time-to-Digital Converter (TDC) to measure the TOF of single-photons. From the repetitive acquisition of photons returning from multiple laser shots, it is possible to accumulate a TOF histogram, so as to identify the laser pulse return from unwelcome ambient light and compute the desired distance information. In order to properly predict the TOF histogram distribution and design each component of the LiDAR system, from SPAD to TDC and histogram processing, we present a detailed statistical modelling of the acquisition chain and we show the perfect matching with Monte Carlo simulations in very different operating conditions and very high background levels. We take into consideration SPAD non-idealities such as hold-off time, afterpulsing, and crosstalk, and we show the heavy pile-up distortion in case of high background. Moreover, we also model non-idealities of timing electronics chain, namely, TDC dead-time, limited number of storage cells for TOF data, and TDC sharing. Eventually, we show how the exploit the modelling to reversely extract the original LiDAR return signal from the distorted measured TOF data in different operating conditions."

Automotive PHY Battles: A-PHY vs Auto-Serdes, Sony Evaluates A-PHY
June 30, 2021 By Leave a Comment
Image Sensors World Go to the original article...
PRNewswire: Valens announces that it has started an evaluation with Sony Semiconductor Solutions to develop and integrate MIPI A-PHY technology into next-generation image sensor products.A-PHY Serdes standard was released by the MIPI Alliance in September 2020 aiming for integration of cameras, sensors and displays in vehicles, while also incorporating functional safety and security. Valens is the first company to market with A-PHY compliant chipsets. Recently, Valens announces a PAC deal to list at NYSE at valuation of $1.16B. (EETimes)
"It's highly important for Sony to integrate the cutting-edge technology into our image sensors, and A-PHY serializer integration will provide significant benefits for our customers," said Kenji Onishi, General Manager, Automotive Business Department, Sony Semiconductor Solutions. "The MIPI ecosystem is growing quickly, and we're happy to be early adopters of this automotive connectivity standard. Valens is in a leading position with A-PHY, which is why it is so important for us to start this collaboration. We believe future models will have even higher resolutions. In addition, our company is preparing to integrate several features into their next-generation sensors, including metadata output, higher framerate, and wider bit depth – all of which will require an ultra-high-speed, long-reach connectivity solution such as MIPI A-PHY. We will continue to support not only A-PHY but also D-PHY, proprietary interfaces, and open-standard interfaces."
MIPI A-PHY standard faces a competition of Automotive SerDes Alliance (ASA) that offers quite similar performance and feature set. SemiEngineering discusses the two standards competition:
"The reason for the separate and independent ASA development isn’t publicly clear. In some of their statements and materials, it is positioned as the only standardized alternative to proprietary schemes, without acknowledging the existence of the MIPI/VESA solutions. And some say that, during the A-PHY definition process, the group split, with one side moving to create the new ASA group.
Some further digging revealed that the main concern seems to be that the A-PHY technology comes from one company, Valens, which contributed it to the standard. However, “MIPI A-PHY, like all MIPI specifications, is made available under royalty-free terms,” said [Peter Lefkin, managing director of the MIPI Alliance.]
Still, the issue for ASA members appears to be that only essential patents get a license. Valens has implemented this in a way that includes non-essential patents, and licensees don’t get access to those patents. A statement from the ASA steering committee noted, “There are examples where the solution of one supplier was successfully made a standard, but there are many examples where it did not work.”
The ASA folks are more interested in a process where multiple companies contribute technology without one company dominating. The ASA effort is licensed under FRAND (free or reasonable and non-discriminatory) licensing.
MIPI’s concern is there may be royalty uncertainty prior to acquiring a license. There apparently has been some history in the automotive realm of companies refusing to license essential patents. Regardless, it’s pretty clear that the A-PHY and the ASA PHY will compete head-to-head. How that competition resolves itself is not yet evident."
SPAD Imaging with No Pile-Up

Image Sensors World Go to the original article...
Politecnico di Milano, Italy, publishes an open access paper in Review of Scientific Instruments "Toward ultra-fast time-correlated single-photon counting: A compact module to surpass the pile-up limit" by S. Farinaa, G. Acconcia, I. Labanca, M. Ghioni, and I. Rech.
"Time-Correlated Single-Photon Counting (TCSPC) is an excellent technique used in a great variety of scientific experiments to acquire exceptionally fast and faint light signals. Above all, in Fluorescence Lifetime Imaging (FLIM), it is widely recognized as the gold standard to record sub-nanosecond transient phenomena with picosecond precision. Unfortunately, TCSPC has an intrinsic limitation: to avoid the so-called pile-up distortion, the experiments have been historically carried out, limiting the acquisition rate below 5% of the excitation frequency. In 2017, we demonstrated that such a limitation can be overcome if the detector dead time is exactly matched with the excitation period, thus paving the way to unprecedented speedup of FLIM measurements. In this paper, we present the first single-channel system that implements the novel proposed methodology to be used in modern TCSPC experimental setups. To achieve this goal, we designed a compact detection head, including a custom single-photon avalanche diode externally driven by a fully integrated Active Quenching Circuit (AQC), featuring a finely tunable dead time and a short reset time. The output timing signal is extracted by using a picosecond precision Pick-Up Circuit (PUC) and fed to a newly developed timing module consisting of a mixed-architecture Fast Time to Amplitude Converter (F-TAC) followed by high-performance Analog-to-Digital Converters (ADCs). Data are transmitted in real-time to a Personal Computer (PC) at USB 3.0 rate for specific and custom elaboration. Preliminary experimental results show that the new TCSPC system is suitable for implementing the proposed technique, achieving, indeed, high timing precision along with a count rate as high as 40 Mcps."

Image Sensors World Go to the original article...
BusinessWire: OmniVision announces its next-generation OH08A and OH08B CMOS sensors―the first 8MP sensors for single-use and reusable endoscopes. Additionally, the new OH08B is the first medical-grade image sensor to use Nyxel NIR technology.The medical-grade OH08A image sensor features a 1/2.5-inch optical format, incorporates 1.4µm PureCel Plus-S pixel and offers 4K2K resolution in a small 7.1 x 4.6mm package for chip-on-tip endoscopes. The OH08B has a 1/1.8-inch optical format, uses a larger 2.0µm PureCel pixel in a 8.9 x 6.3mm package and features OmniVision’s Nyxel technology with enhanced NIR sensitivity.
“Our next-generation OH08A/B 8MP image sensors are targeted at endoscopes with a 10-12mm outer diameter, such as gastroscopes, duodenoscopes, amnioscopes, laparoscopes and colonoscopes. They deliver higher image quality, up to 4K2K resolution at 60 fps, greatly improving the doctor’s ability to visualize the human anatomy during these important procedures,” said Richard Yang, senior staff product marketing manager at OmniVision. “In the OH08B, we’ve taken our sensor to the next level by adding Nyxel technology, which offers better performance in color and IR sensitivity, enabling doctors to see sharper video during NIR, fluorescence, chromo-endoscopy and virtual endoscopy procedures. Also, higher sensitivity results in less illumination, thus reducing the heat at the tip of the endoscope.”
The OH08A offers 8MP Bayer still frame or 4K video in real time. It features 4-cell three-exposure HDR with tone mapping for improved HDR output at 1080p60 or native 4K2Kp60 resolution and two-exposure staggered HDR support.
The OH08B's Nyxel technology provides 3x QE improvement at both the 850nm and 940nm wavelengths. It allows the use of lower-power IR illumination, resulting in significantly reduced chip-on-tip power consumption.
Other key features include a 15.5 degree CRA for the OH08A and 11 degree CRA for the OH08B, enabling the use of lenses with large field of view and short focus distance; PWM output LED drivers; and 4 lane MIPI output with raw data. These sensors are stereo ready with frame synchronization to support a host of depth perception applications. Additionally, they are autoclavable for reusable endoscope sterilization.
The OH08A/B image sensors are available for sampling now in a chip scale package.

Sony announces the upcoming release of IMX585, a 1/1.2-type 4K CMOS sensor for security cameras, which delivers approximately 8 times the DR of the company's conventional model in a single exposure.
The new product belongs to the new “STARVIS 2” series featuring high sensitivity and 88dB HDR in a single exposure. It also increases the NIR sensitivity by approximately 1.7x compared to conventional model. The new sensor can also be used in multi-exposure mode, delivering a HDR of 106 dB.Sony also plans to launch IMX662, a 1/3-type 2K resolution image sensor employing “STARVIS 2” to deliver an 88 dB DR in a single exposure. Samples are scheduled to be made available for shipment within this year.
Generally, in order to provide HDR imaging, multi-exposure image capture is required, and the multiple images recorded at differing exposure times are composited into a single shot. This results in issues with artifacts, which can cause false recognition when using AI, especially when capturing moving subjects. The new product adopts Sony’s new proprietary “STARVIS 2” technology, which delivers both high sensitivity and HDR imaging.

To further increase the volumetric resolution beyond the Rayleigh diffraction limit, and achieve the quantum limit, we are also developing dedicated protocols based on quantum Fisher information. However, for the quantum advantages of the proposed devices to be effective and appealing to end-users, two main challenges need to be tackled. First, due to the large number of frames required for correlation measurements to provide an acceptable SNR, quantum plenoptic imaging would require, if implemented with commercially available high-resolution cameras, acquisition times ranging from tens of seconds to a few minutes. Second, the elaboration of this large amount of data, in order to retrieve 3D images or refocusing 2D images, requires high-performance and time-consuming computation. To address these challenges, we are developing high-resolution SPAD arrays and high-performance low-level programming of ultra-fast electronics, combined with compressive sensing and quantum tomography algorithms, with the aim to reduce both the acquisition and the elaboration time by two orders of magnitude. Routes toward exploitation of the QPI devices will also be discussed."
Radiation Detection with iPhone 6s Camera

Nature publishes a paper "The suitability of smartphone camera sensors for detecting radiation" by Yehia H. Johary, Jamie Trapp, Ali Aamry, Hussin Aamri, N. Tamam & A. Sulieman from Queensland University of Technology (Australia), King Saud Medical City (Saudi Arabia), Princess Nourah Bint Abdulrahman University (Saudi Arabia), and Prince Sattam Bin Abdulaziz University (Saudi Arabia.)"The advanced image sensors installed on now-ubiquitous smartphones can be used to detect ionising radiation in addition to visible light. Radiation incidents on a smartphone camera’s Complementary Metal Oxide Semiconductor (CMOS) sensor creates a signal which can be isolated from a visible light signal to turn the smartphone into a radiation detector. This work aims to report a detailed investigation of a well-reviewed smartphone application for radiation dosimetry that is available for popular smartphone devices under a calibration protocol that is typically used for the commercial calibration of radiation detectors. The iPhone 6s smartphone, which has a CMOS camera sensor, was used in this study. Black tape was utilized to block visible light. The Radioactivity counter app developed by Rolf-Dieter Klein and available on Apple’s App Store was installed on the device and tested using a calibrated radioactive source, calibration concrete pads with a range of known concentrations of radioactive elements, and in direct sunlight. The smartphone CMOS sensor is sensitive to radiation doses as low as 10 µGy/h, with a linear dose response and an angular dependence. The RadioactivityCounter app is limited in that it requires 4–10 min to offer a stable measurement. The precision of the measurement is also affected by heat and a smartphone’s battery level. Although the smartphone is not as accurate as a conventional detector, it is useful enough to detect radiation before the radiation reaches hazardous levels. It can also be used for personal dose assessments and as an alarm for the presence of high radiation levels."
Yole Updates about 2020-21 CIS Market and Market Shares
June 25, 2021 By Leave a Comment
Image Sensors World Go to the original article...
Yole Developpement publishe an article "COVID-19 & Huawei ban winds of change on the CIS industry – Quarterly Market Monitor":2020 saw CIS revenues reach $20.7B with an annual growth of 7.3%. As with other semiconductor products, Yole’s analysts noted that long production cycles and the activity of markets such as consumer, automotive, security, and industrial led to challenges in procurement of CIS at the end of 2020. In 2021, Yole’s imaging team expects a more stable situation. Q1-2021 has been very good due to some production overflow identified from Q4-2020, leading to a 7% better quarter compared to Q1-2020.
2020 was a very unusual year for the CIS industry. Everybody had the COVID-19 situation in mind, and, indeed, it created a temporary disruption in the supply chain which had to be made up towards year-end. Another disruptive aspect was the Huawei ban and its effect on the market between Q3 2020 and Q4 2020, especially for Sony. However, it did not lead to a CIS market collapse thanks to the increasing number of cameras per mobile and a stable average selling price overall.
All these events combined allowed for the CIS industry to maintain significant growth in 2020.
“Q1 is seasonally a typically lower revenue quarter, though there was fear of shortages in the overall semiconductor industry,” explains Chenmeijing Liang, Technology & Market Analyst within the Photonics, Sensing & Display Division at Yole. “At Yole, we believe that the effect here is more linked to supply chain issues rather than real capacity issues for CIS.”
“Sony was hit the hardest by these crises, as it was highly exposed to the mobile market and subsequent international trade tensions; the toll on Sony’s revenue in Q4 2020 is notable,” asserts Pierre Cambou, Principal analyst in the Photonics and Sensing Division at Yole.
Sony, of course, remains the market leader, and though they did lose some market share in Q4-2020, they regained traction in Q1-2021. However, they are being challenged by increased competition. In comparison, their nearest competitor Samsung was more protected from this market shake-up due to its vertical integration. Their recently released line of 0.7µm pixel sensors targeting the mobile market helped them seize some of the new opportunities, with some OEMs, such as Xiaomi, benefiting from Huawei’s disappearance.
Some CIS fabless players, like ON Semiconductor, may not have the ability to secure capacity from TSMC, as Sony did. They did ok during 2020 but could have done better by surfing the automotive and logistic camera market growth.
But other fabless players, probably Chinese, like Smartsens Technology and Omnivision, diversified their sourcing long ago and grew far more.
