Tripurari Singh, Image Algorithmics (US); Mritunjay Singh, Image Algorithmics presented a paper titled "RGBC-IR: A CFA for single exposure dark flash" at Electronic Imaging 2025.
Abstract: Modern RGB-IR cameras have evolved to capture accurate colors and NIR from a single sensor. While these cameras can employ their RGB images to effectively denoise IR, they contain too few IR pixels to do the reverse: denoise RGB with IR.Improving low light RGB with an IR illuminator is an important feature for upcoming automotive applications where cabins have to be kept dark at night so as not to distract the driver. Current solutions to this problem either discard the IR cut filter and take separate RGB and IR exposures and suffer from poor colors. Or employ a bulky beam splitter architecture with separate RGB and IR sensors.We propose a camera with a novel RGBC-IR color filter array containing clear pixels that are sensitive to both visible light and IR. Its RGB pixels feature an IR attenuating coating while its IR pixels contain a black filter that blocks visible light.Mulitspectral demosaicking techniques are used to reconstruct RGB and IR images, as well as a high SNR luminance image containing the Clear, RGB and IR signals. Fusion techniques developed for beam splitter RGB-IR cameras are used to denoise RGB and IR using the luminance.

IDS launches new industrial camera series featuring Prophesee
Image Sensors World Go to the original article...
PARIS, France and OBERSULM, Germany – March 5, 2025 - IDS Imaging Development Systems GmbH, market leader in industrial machine vision, and Prophesee SA, inventor of the most advanced neuromorphic vision systems, today announced that IDS’ new uEye EVS camera line incorporates the high-speed, dynamic range and data efficiency of the Prophesee-Sony IMX636HD event-based vision sensor to offer new capabilities for industrial machine vision applications.
The result of extensive collaboration between the two companies, the solution features Prophesee’s proven neuromorphic approach to capturing fast-moving objects with significantly less data processing, power and blur than traditional frame-based methods. With these capabilities, the uEye EVS camera is the ideal solution for applications that require real-time machine vision processing at very high speed, such as optical monitoring of vibrations or high-speed motion analysis.
The camera benefits from Prophesee’s event-based vision’s ability to capture only relevant events in a scene. In contrast to conventional image sensors, it does not capture every image completely at regular intervals (frames) but only reacts to changes within a scene. It transmits events depending on when and where the brightness in its field of view changes - for each individual sensor pixel. The temporal resolution, i.e. the minimum measurable time difference between two successive changes in brightness, can be less than 100 microseconds.
The sensor is supported by Metavision SDK, a seamlessly integrated suite of software tools and models, APIs, and other training and development resources from Prophesee for efficient evaluation, visualization, and customization.
"This partnership combines our mutual areas of expertise to realize the benefits of event-based vision, including remarkable temporal resolution which make the cameras optimised for analysing highly dynamic scenes. It enables best conditions for capturing fast object movements without loss of information, comparable to an image-based frame rate of more than 10,000 images per second," explains Patrick Schick, Product Owner 3D & Vision Software. “At the same time, the sensor ignores all motionless areas of its field of view and thus generates 10 to 1000 times less data than image-based variants. This saves memory and computing time.”
“IDS cameras are well known to address the toughest machine vision use cases and with the incorporation of Prophesee event-based vision technologies, it strengthens its offering to provide far more performance, power efficiency and accuracy, even in the most challenging conditions,” says Luca Verre, CEO and co-founder of Prophesee. “We are excited to see how the efforts of this tight collaboration have resulted in the new uEye EVS camera which leverages the potential of our sensors and development environment to deliver new value to its customers.”
About IDS Imaging Development Systems GmbH:
IDS Imaging Development Systems GmbH is a leading manufacturer of industrial cameras and pioneer in industrial image processing. The owner-managed, environmentally certified company develops high-performance and versatile 2D and 3D cameras as well as models with artificial intelligence (AI) or with streaming/event recording feature. The almost unlimited range of applications covers multiple non-industrial and industrial sectors of equipment, plant and mechanical engineering.
Since its foundation in 1997 as a two-man company, IDS has developed into an independent, ISO and environmental-friendly certified family business with around 320 employees. The headquarters in Obersulm, Germany, is both a development and production site. With subsidiaries in the USA, Japan, South Korea and the UK, as well as further representative offices in France, Benelux and India, the technology company has a global presence.
About Prophesee
Prophesee is the inventor of the world’s most advanced neuromorphic vision systems. Prophesee’s patented sensors and AI algorithms, introduce a new computer vision paradigm based on how the human eye and brain work. Like the human vision, it sees events: essential, motion information in the scene, not a succession of conventional images. This breakthrough method allows for unprecedented speed (>10 000fps time resolution equivalent), dynamic range (>120dB), data volume (10x to 1000x less) and power efficiency (<10 mW). Prophesee bio-inspired revolution opens a new path to absolute efficiency and safety in autonomous driving, IoT and Industry 4.0. Prophesee reveals the invisible.

SK hynix plans to exit CMOS image sensor business
Image Sensors World Go to the original article...
Various news agencies reporting that SK hynix is exiting the CIS business to focus on AI.
Amid the AI-driven HBM boom, SK hynix is exiting its non-core CMOS image sensor (CIS) business, according to ZDNet and Edaily.
The ZDNet report suggests that SK hynix used to supply CMOS sensors for Samsung’s Galaxy Z3 and Chinese smartphones, but struggled to expand due to weak market demand and rising competition from Chinese newcomers.
According to SK hynix, its CIS division, launched in 2007, gained expertise in logic semiconductors beyond memory. However, the company decided to shift resources from CIS to AI memory to strengthen its AI-focused strategy, as per ZDNet.
Another report from fnews notes that SK hynix entered the image sensor market in 2008 by acquiring Silicon File. In 2019, it established a CIS R&D center in Japan and launched the “Black Pearl” sensor brand.
However, while trailing behind Sony and Samsung on the CIS business, SK hynix has been gradually downsizing the division, according to Edaily.
In late 2024, the company placed its CIS development team under the Future Technology Research Institute amid ongoing discussions about the business’s declining profitability, the Edaily report indicates.

SK Hynix is existing the CMOS image sensor (CIS) business, TheElec has learned.
The company will instead focus fully on AI memory products. Those working at its CIS business unit will be transferred to teams working on high-bandwidth memory (HBM).
In a recent internal communication event with employees, SK Hynix said the AI era has come and that the company has achieved “great results” in the AI memory sector.
The company was in the middle of a “great transition” to become a core AI company, SK Hynix told employees.
Technology and expertise that its CIS business unit will be crucial in solidifying its position as a global AI company, SK Hynix added.
SK Hynix started its CIS business in 2007 and since then attempted to expand its market share in the mobile market. But the unit continued to mark low profitability and its existence was always questioned.
In its year’s end reshuffle lats year, the business unit was moved to be under the supervision of the Future Technology Lab. These teams are more research oriented than teams under the supervision of the CEO.
SK Hynix CEO Kwak Noh-jung was also known to be strongly in favor of continuing the CIS business unit prior to the exit.
The company, during the vent, also said it plans to become a full stack AI memory provider.
