SiOnyx vs Apple iPhone15 lawsuit

Link: https://appleinsider.com/articles/25/01/09/apple-fights-patent-lawsuit-over-iphone-15-camera-tech

In September, Apple was the target of a patent infringement lawsuit from SiOnyx, for allegedly encroaching on patents for full-color night vision imaging sensors.

At the time, it was claimed that Apple had infringed on the patents, referred to as "Pixel Isolation Elements, Devices, and Associated Methods," discussing improvements to photosensitive devices. By using silicon-based photonics, the complaint said that companies could create smaller, lower-cost, and higher-performance photonic devices for imaging purposes.

In December, SiOnyx amended the complaint to include that Apple had pre-suit knowledge of three patents, reports Law.com. Apple also connected in May 2014 to talk about technical developments.

In an August 2017 meeting over trench isolation structures and black silicon technology, as mentioned in the patents, SiOnyx also shared a presentation with Apple employees.

On January 8, Apple responded to the complaint by filing a motion to strike some of the new allegations. Working for Apple, attorney Michael D. Strapp of DLA Piper wanted for some of the case to be dismissed, because SiOnyx failed to state a claim.

Canon announces 410MP full-frame sensor

Press release: https://global.canon/en/news/2025/20250122.html

Canon develops CMOS sensor with 410 megapixels, the largest number of pixels ever achieved in a 35 mm full-frame sensor

TOKYO, January 22, 2025— Canon Inc. announced today that it has developed a CMOS sensor with 410 megapixels (24,592 x 16,704 pixels), which is the largest number1 of pixels ever achieved in a 35 mm full-frame sensor. This sensor is expected to be used in applications that demand extreme resolution in various markets including surveillance, medicine, and industry.

The newly developed CMOS sensor features a resolution equivalent to 24K (198 times greater than Full HD, and 12 times greater than 8K). This enables users to crop any part of the image captured by this sensor and enlarge it significantly while maintaining high resolution. While many CMOS sensors with a super-high pixel count are medium-format or larger, this extreme resolution sensor is compacted into a 35 mm full-frame format. This allows it to be used in combination with lenses for full-frame sensors, and it is expected to contribute to the miniaturization of shooting equipment. As data readout of a CMOS sensor tends to take longer as the number of pixels increases, achieving a CMOS sensor with a super-high pixel count requires advanced signal processing technology. The newly developed sensor employs a back-illuminated stacked formation in which the pixel segment and signal processing segment are interlayered and also includes a redesigned circuitry pattern. As a result, the sensor is capable of achieving a super-high readout speed of 3,280 megapixels per second, delivering video at 8 frames per second2.

This sensor3 also features a “four-pixel binning” function that virtually treats four adjoining pixels as one, thereby improving sensitivity and making it possible to capture brighter images. When this function is in use, the sensor can capture 100-megapixel video at 24 frames per second.

By leveraging the technology it has accumulated over many years as a leading imaging company, Canon has developed breakthrough products including CMOS sensors with super-high pixel count and ultra-sensitivity, and SPAD sensors, which detect faint traces of light even in dark areas. Canon will continue to advance its technology and contribute to the transformation and further development of society.

Additional information
The sensor is scheduled to be displayed at the Canon booth at SPIE Photonics West, a leading global conference for optics and photonics held in San Francisco from January 28-30, 2025.

Singular Photonics launches SPAD imagers at SPIE Photonics West

Press release: https://singularphotonics.com/singular-photonics-emerges-from-stealth-with-portfolio-of-spad-based-image-sensors/

Startup introduces range of sensors with layers of advanced computation to extract valuable information from images.

Edinburgh, UK – January 23, 2025 – Singular Photonics emerged from stealth mode today, launching a new generation of image sensors based on single photon avalanche diodes (SPADs). A spin-out from the University of Edinburgh lab of digital imaging pioneer Professor Robert Henderson, Singular is one of the first companies to bring advanced computation to SPAD-based image sensing, enabling in-pixel and cross-pixel storage and computations at the lowest light levels to reveal previously invisible details of the material world and its photon events.

The company will showcase its products for the first time at next week’s SPIE Photonics West event in San Francisco.

SPADs use the “avalanche” effect in semiconductors to convert light directly into an electrical current, without the need for cooling or amplification. While most commercial SPAD-based image sensors have been limited to time-resolved counting of photons, Singular’s core innovation lies in complex layers of computation beneath 3D-stacked SPAD sensors, comparable to the way FPGAs and GPUs revolutionized parallel computing by conducting high-speed, localized processing.

Prof Henderson leads the University of Edinburgh’s CMOS Sensors and Systems Group. In 2005, he designed one of the first SPAD image sensors in nanometer CMOS technologies, leading to the first time-of-flight sensors in 2013, which today perform an autofocus-assist feature in more than a billion smartphones worldwide.

“There can be no doubt that SPAD sensors are the future of digital imaging, but their use to date in commercial devices hasn’t extended much beyond time-resolved counting of photons,” said Prof Henderson. “Computational cleverness can be the difference. We are building next-generation imaging sensors, where the computation is done digitally at the pixel level – exactly where the photons arrive.”
Simultaneously capturing depth and temporal dimensions to generate 4D images that provide deep, data-rich insights, Singular’s noiseless sensors enable more information to be extracted from light, supporting applications ranging from consumer and automotive electronics to the scientific and medical fields. The company’s approach transforms SPAD sensors into 3D stacked computational engines capable of performing a wide range of sophisticated tasks, such as real-time photon counting, timing, and advanced processing techniques, including in-pixel histograms, statistical analysis and autocorrelation.

Singular is launching with two sensors, both of which are available today:
 
Andarta, developed in collaboration with tech giant Meta, has a miniature form factor combined with high sensitivity, and is optimized for use in a number of medical imaging modalities. The sensor supports multiple modes of operation including in-pixel autocorrelation measurements, and represents a significant step closer to SPAD integration in the wearables space. For example, Andarta enables monitoring of the rate of cerebral blood flow, monitoring rapid fluctuations in light as it passes through tissue, at depths not currently possible with current sensors.

 Sirona, the company’s first product, is a 512 pixel SPAD-based line sensor capable of time-correlated single photon counting (TCSPC) and enabling Raman spectroscopy, fluorescence lifetime imaging microscopy (FLIM), time-of-flight, and quantum applications. With on-chip histogramming and time binning capability, the sensor has the potential to revolutionize spectroscopy applications.
Singular has already inked multiple deals for its sensors with some of the world’s leading instrumentation companies, and expects to announce more collaborations in 2025.

 “We are in a unique position where we already have commercially available products and are generating revenue in our first year of incorporation,” said Shahida Imani, CEO of Singular Photonics. “With new, even more advanced sensors coming to the market in 2025, we are well positioned to lead the SPAD-driven imaging revolution.”

Sony stacked CIS+iToF sensor (IEDM 2024)

Article (in German): https://www.pcgameshardware.de/Wissenschaft-Thema-237118/News/Fuer-Kameras-Sony-stapelt-Farb-Tiefensensor-keine-Verzerrungen-mehr-1462040/

English translation from Google Translate (with some light editing) below:

 

Depth sensors, which provide an image with spatial information, have become increasingly widespread in recent years. They can be used, for example, to create 3D scans or for targeted, subsequent blur effects - for example in smartphone cameras. In most cases, so-called ToF sensors (Time of Flight) are used, in which each pixel is measured when previously radiated infrared light is reflected back.

Not next to each other, but on top of each
So far, however, there has been a problem in the implementation in combination with normal camera sensors. Either the ToF sensor is located next to the camera sensor. Then there are are concealed areas through the different angles, but above all on edges, and not every color value can be assigned a depth value. Or ToF and color pixels sit on the same sensor and take away the space from each other. In other words: The resolution is reduced.

However, the camera division of Sony now claims to have found a way out. At the IEDM 2024 semiconductor trade fair, a combination sensor was presented in which the camera sensor is located directly above the depth sensor. This is made possible by the use of a new material: normally the color pixels would be located on silicon, but the broadband light would be absorbed and thus the depth pixels covered. However, Sony has apparently solved this problem by means of a new construction on a broadband transparent, organic photo-leading film. Visible wavelength hits the color sensors, while infrared light falls further down on the IR pixels of the ToF sensor.



Above each ToF pixel, which each occupies 4um, there are four RGB pixels with 1um each. In total, there is talk of a resolution of 1004 x 756 pixels for the depth map and 4016 x 3024 pixels for the color image. At least in this respect, the prototype has apparently already reached a usable area.

 

However, it is still unclear whether and when corresponding sensors should go into mass production. However, if Sony can potentially eliminate existing problems, the wide availability of such a sensor would offer numerous options. For example, you could simplify the creation of high-resolution 3D scans for games and movies and also make the data collection of robots significantly more reliable.
