Canon MS-510 low light camera

Press release: https://www.usa.canon.com/newsroom/2026/20260415-camera

Canon U.S.A. Sets New Standard in Low-Light Imaging with the Launch of the MS-510 Multi-Purpose Camera at NAB 2026

Featuring a new Canon 1-inch SPAD sensor, the MS-510 delivers impressive low-light and long-range performance for ultra-low-light environments 

MELVILLE, N.Y., April 15, 2026 – Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the release of the MS-510, an innovative multi-purpose camera engineered to meet the rigorous demands of ultra-low-light full-color video shooting. Building on the success of the MS-500, the new MS-510 is designed to deliver high-fidelity captures of everything from nocturnal wildlife and natural nightscapes to high-security areas such as seaports, public infrastructure facilities, and national borders where "seeing the unseen" is a mission-critical requirement.

In response to increasing demands for excellent performance in near-total darkness, the MS-510 features a new Canon 1-inch Single-Photon Avalanche Diode (SPAD) sensor with the world’s highest number of pixels at approximately 3.2 million with improved Near-Infrared (NIR) sensitivity.

By leveraging this technology, the camera achieves a minimum subject illumination of 0.0006 lux, a significant improvement over the 0.001 lux of its predecessor. This allows for bright, full-color imaging in ultra-low-light environments where traditional cameras can fail. Furthermore, the MS-510 boasts improved NIR capabilities, providing a tactical advantage for night-mode operations and long-distance detection.

The MS-510 is not just a camera; it is a sophisticated tool for critical infrastructure monitoring and law enforcement. Key features include:

  •  Broadcast-Grade Optics: Equipped with the broadcast industry standard B4 mount, the MS-510 has a built in magnifying optical system offering compatibility with Canon’s extensive lineup of 2/3-inch ultra-telephoto broadcast zoom lenses, enabling crystal-clear identification over vast distances.
  •  Advanced Image Processing: Integrated Haze Compensation automatically reduces the interference of mist and haze while adjusting contrast, and Smart Shade Control corrects for highlights and shadows to maintain image integrity in challenging lighting conditions.
  •  Customizable Imaging Profiles: Users can create up to 20 customized image quality settings or utilize Custom Picture Presets to prioritize wide dynamic range or maximum noise reduction depending on the environment.

Designed to fit into existing security ecosystems, the MS-510 shares common protocols with the MS-500, including NU, Pelco-D®, ONVIF®, and WebView. It offers versatile output options, including 3G/HD-SDI for high-quality video feeds and a LAN terminal for IP-based camera control and distribution.

Foveated imaging with optical folding

Jinwen Wei and Liangcai Cao, "Compact Neural Pancake Camera for High-Perceptual-Quality Foveated Imaging," ACS Photonics (2026).

Link: https://doi.org/10.1021/acsphotonics.6c00691 

Pancake catadioptric optics utilize optical folding to effectively reduce the optical-path thickness in virtual-reality display systems. However, limited optical throughput and optical degradation make image reconstruction for pancake cameras severely ill-posed, hindering broader imaging applications. In this article, we propose a neural pancake camera with adaptive-prior deconvolution, achieving compact, high-perceptual-quality imaging. By introducing latent-space projection, adaptive prior deconvolution alleviates the trade-off between pixel fidelity and perceptual quality and addresses the excessive smoothing inherent in conventional pixelwise optimization. The proposed neural pancake camera reduces the ratio of axial length to physical aperture diameter by 3.2 times compared with other flat cameras with high imaging quality. Experiments and ablation studies substantiate that the proposed adaptive prior deconvolution improves perceptual quality by 70%, as measured by CLIP-IQA, while also outperforming the state-of-the-art deep learning models on pixel-level fidelity. As a representative application of the proposed neural Pancake camera, this work further showcases bioinspired foveated imaging, highlighting its potential for bandwidth-efficient imaging in next-generation edge and portable devices.

Canon "twisted photodiode" paper (IISW2025 special issue)

In a paper titled "Design and Optimization of a Twisted Photodiode Pixel Structure for All-Directional Phase-Detection Autofocus CMOS Image Sensors" a team from Canon write:

To achieve an all-directional and high-speed, high-accuracy autofocus (AF) function, we propose a CMOS image sensor with a Twisted Photodiode (PD) structure. The developed 3D-stacked back-side illuminated (BSI) sensor employs the Twisted PD, which enables equivalent angular response characteristics in both the horizontal and vertical directions for the two PDs integrated within a single pixel, thereby realizing AF detection for all pixels and all directions. This paper describes the Twisted PD structure that enables all-directional AF and presents an analysis of charge transfer behavior in this unique 3D configuration. In this paper, “all-directional” refers to robustness with respect to subject direction.

This paper was published in the IISW2025 special issue of Sensors.

400x400 pixel stacked CIS HDR sensor for AR/VR applications

In a June 2026 paper titled "A 400×400 3.24-μm 117-dB Dynamic Range Three-Layer Stacked Digital Pixel Sensor With Triple Quantization and Fixed Pattern Noise Correction" published in IEEE Trans. Electron Devices, a team from Brillnics, Meta, and SesameAI* write:

This article presents a 400×400 digital pixel sensor (DPS) with a 3.24 μm pixel pitch, fabricated using a 45/40/40 nm three-layer stacked process. The sensor achieves single-exposure high dynamic range (SEHDR) through overlapped triple quantization (3Q), fixed pattern noise correction (FPN-C), and black level correction (BLC). An on-chip image signal processor (ISP) is integrated to support defect pixel correction (DPC), SEHDR linearization, and gamma correction. Sparse transmission (ST) is incorporated to reduce transmitted data volume and, consequently, transmission power consumption. A wafer-level chip-scale package (WLCSP) with two redistribution layers (RDLs) is employed, resulting in a compact form factor of 2.47×1.85 mm^2. This work achieves a dynamic range (DR) of 117 dB while consuming 2.45 mW at 30 frames/s (fps), yielding a figure of merit (FoM) of 0.0046 e- rms  pJ, and is developed to meet the growing demands of augmented reality (AR) and virtual reality (VR) applications.

Low-cost ultra-high-speed imager using spatio-temporal encoding

In a preprint titled "Low-cost passive single-shot ultrafast imaging at 685 Gfps" EÅŸlik et al write: 

Capturing ultrafast transient phenomena conventionally requires streak cameras or computational imaging based on compressed sensing, which lead to complex and costly systems. In this Letter, we demonstrate, to the best of our knowledge, the first fully passive single-shot ultrafast imaging architecture assembled entirely from off-the-shelf, low-cost components. A commercial microlens array combined with a stack of standard microscope cover glasses maps temporal information into multiple spatial channels, and a consumer-grade CMOS image sensor records all delayed replicas within a single camera exposure. The proposed system has a total hardware cost below US$500 and captures the evolution of a picosecond laser pulse with a temporal sampling interval of 1.46 ps, an effective frame rate of 685 Gfps, and a sequence depth of ten frames. The temporal fidelity of the system is verified by recovering the expected Gaussian pulse profile, and the spatial resolution is characterized through a point-source measurement with a point spread function of 1.86 and 1.62 pixels full width at half maximum along the horizontal and vertical directions, respectively. The proposed architecture presents an alternative approach to single-shot ultrafast imaging with a simple, low-cost, computation-free, and fully passive design.

Schematic of the proposed low-cost passive spatially multiplexed ultrafast imaging system. A microlens array generates replicated image channels, each of which experiences a different optical delay introduced by a stack of standard microscope cover glasses. Temporally delayed replicas are simultaneously recorded within a single camera exposure using a consumer-grade CMOS sensor. 

Single-shot reconstruction of the temporal evolution of a picosecond laser pulse. Each sub-image corresponds to a different optical delay introduced by the proposed spatial multiplexing architecture. The sequence is recovered from a single camera exposure with a temporal spacing of 1.46 ps between the frames.
 

Normalized total intensity extracted from reconstructed frames as a function of relative temporal delay. The measured temporal profile follows a Gaussian distribution (dashed curve), which confirms the accurate preservation of the pulse dynamics.

AlpsenTek raises another round of funding for its hybrid vision sensor

AlpsenTek Completes Series B+ as Hybrid Vision Sensors Become a New Gateway to the AI-Powered Physical World

SHENZHEN, China — March 17, 2026AlpsenTek, a pioneer in hybrid vision sensor technology, today announced the completion of a Series B+ financing round and the total fund-rasing has surpassed 100 million USD.

The B+ round was jointly backed by BEIDM, Guangdong Finance Fund Management, GAC Capital, Circumference Capital, Changjiang Capital, Bluetrum, UNICC Capital, Zhichen Investment, Wofo Venture Capital, and Sunyes.

The new funding will support continued core technology development, large-scale product manufacturing, and global market expansion, accelerating the industrial adoption of next-generation AI vision sensing technologies.

The Growing Need for Real-Time Perception in Physical AI

As artificial intelligence moves beyond the digital world and increasingly interacts with the physical environment, real-time environmental perception is becoming a fundamental infrastructure for intelligent systems.

Traditional vision sensors, which rely on fixed-frame-rate image capture and full-pixel data acquisition, are gradually struggling to meet the emerging requirements of intelligent perception systems that demand high speed, low latency, and high dynamic range.

Hybrid Vision Sensing: A New Path for AI Machine Vision

AlpsenTek’s Hybrid Vision Sensor (HVS) technology introduces a new technical paradigm for machine vision systems.

The technology integrates frame-based image sensing and event-based sensing mechanisms on a single sensor chip, enabling devices to simultaneously capture both image information and brightness change signals within a scene. This provides AI systems with visual inputs that are both more efficient and more representative of real-world dynamics.

If traditional image sensors record “what the world looks like,” hybrid vision sensors capture both “what the world looks like” and “how the world is changing.”

Dual-Modality Perception for Next-Generation AI

Compared with vision systems that rely solely on frame-based images, hybrid vision sensors can detect scene changes with much higher temporal resolution while maintaining full image output capability.

This dual-modality perception approach allows AI systems to achieve more stable and efficient visual perception in high-speed motion, high dynamic range, and complex lighting environments.

For rapidly developing AI applications—including robotics, autonomous driving, and intelligent devices—machines must not only see two-dimensional image details, spatial structure, and color, but also understand how environments evolve over time.

By introducing the temporal dimension alongside traditional visual information, hybrid vision sensors enable machines to more effectively perceive object motion, interactions, and environmental changes, significantly enhancing a system’s ability to understand the real world.

Reducing Data Redundancy for Efficient Edge AI

At the same time, traditional visual systems generate large amounts of redundant data during video capture, requiring substantial computational resources for processing.

Hybrid vision sensors adopt an event-driven sensing mechanism, outputting key information only when changes occur in a scene. This reduces redundant data generation at the source and provides more efficient data input for edge AI systems.

In the AI era, vision sensors are evolving from simple imaging devices into core interfaces through which machines perceive and understand the physical world.

CEO Perspective

Deng Jian, founder and CEO of AlpsenTek, said the rapid transition of AI from digital environments into the real world is reshaping the role of perception technologies.

“Artificial intelligence is rapidly moving from digital space into the real world,” Deng said. “Future AI systems—whether robots, intelligent devices, or automated systems—will require continuous, real-time perception of the physical environment. Hybrid vision sensors were developed to meet this demand. By simultaneously providing image information and motion-change data, we aim to build a more efficient visual perception foundation for the next generation of intelligent systems.”

Building a Hybrid Vision Product Ecosystem

As a key innovator in hybrid vision technology, AlpsenTek has established a complete proprietary technology stack spanning pixel architecture, chip design, and vision algorithms, and has been among the first globally to achieve large-scale production of hybrid vision sensors.

In 2025, the company introduced the APX014 (ALPIX-Pizol) hybrid vision sensor designed for edge AI perception applications, along with the APX002 (ALPIX-Maloja) pure event-based vision sensor.

Together with the previously released APX003 series and APX004 series, the company has formed a growing product portfolio targeting applications across robotics, wearables, smart home devices, automotive electronics, and consumer electronics.

Accelerating Industry Adoption

AlpsenTek is currently collaborating with several leading global technology companies to advance the large-scale adoption of hybrid vision sensors in intelligent devices and AI systems.

Deng said the company is entering a stage of acceleration as AI vision technologies move toward mass deployment.

“We are now at a pivotal moment for AI vision technologies to move into large-scale applications,” Deng said. “Over the next decade, countless intelligent systems will enter the real world, and visual perception will be one of their most fundamental technologies. Our goal is to make hybrid vision sensors one of the key perception interfaces for next-generation intelligent devices.”

As AI and intelligent hardware continue to evolve, new visual perception technologies are entering an unprecedented phase of opportunity. AlpsenTek said it will continue advancing core technological innovation and product commercialization to expand hybrid vision sensing into more real-world applications.

In an era where AI is moving into the physical world, machines must first learn to see the world—and see its changes—efficiently.

SmartSens unveils SC5A6XS 1-inch 50MP sensor, brings advanced HDR tech, 4K 120fps support

Chinese image sensor maker SmartSens has introduced a new camera sensor aimed at flagship smartphones. The SC5A6XS brings a 50-megapixel 1-inch format and focuses on improving dynamic range and video capabilities. The announcement highlights upgrades in HDR processing, low-light imaging, and power efficiency, setting the stage for next-generation mobile photography.

The SC5A6XS is built on a 22nm stacked process and integrates the brand’s upgraded Lofic HDR 3.0 technology. This system enhances image quality in challenging lighting by capturing a wider range of brightness levels. With a peak dynamic range of 115dB, the sensor aims to preserve highlight details while retaining shadow information in high-contrast scenes.

The HDR system works through multi-frame fusion within a single exposure, which also helps reduce motion artefacts. This is particularly useful in video scenarios where subjects or the camera are in motion. The sensor supports 4K video at 120fps, along with 4K 60fps recording in HDR mode, making it suitable for advanced video use cases on smartphones.

In terms of hardware, the sensor features a 1.6μm pixel size and incorporates SFCPixel technology to improve light sensitivity. With higher sensitivity and reduced read noise, it is designed to produce clearer images in dim conditions without excessive grain.

Autofocus is handled through a combination of full-pixel AllPix ADAF and partial pixel phase detection, allowing faster and more reliable focusing across different lighting environments. Additionally, the company has worked on reducing power consumption, with an approximate 11 percent improvement in HDR mode, which may help control device heating during extended video recording.

The SC5A6XS has already entered the sampling phase and is expected to move into mass production in the second quarter of 2026. It is likely to appear in upcoming flagship smartphones, probably the Huawei Pura 90 series, being the likely candidate, focusing heavily on camera performance.

News: https://www.sony-semicon.com/en/news/2026/2026031701.html 

Sony Semiconductor Solutions to Release 4K Image Sensor for Security Cameras with the Industry’s Smallest 1.45 µm LOFIC Pixels
Contributing to improved recognition precision with high image quality in high-contrast environments and dark scenes

Atsugi, Japan — Sony Semiconductor Solutions Corporation (Sony) today announced the upcoming release of the IMX908, a 4K CMOS image sensor for security cameras with the industry’s smallest 1.45 µm LOFIC pixels.

The new sensor uses the newly developed LOFIC pixels to achieve 96 dB high dynamic range imaging at 4K resolution with a single exposure. Building on this, improved low-light performance delivers high-quality imaging with reduced highlight blowout, loss of shadow detail, and noise in both high contrast environments and dark locations compared to conventional products.

The new sensor will expand Sony’s lineup of products with both high-resolution and high dynamic range for security camera applications, which require high-precision image recognition in a wide range of indoor and outdoor environments, thereby contributing to a safer and more secure society.

Security cameras have been widely used not just for security surveillance, but also in broad applications including monitoring public spaces such as urban areas and other facilities. As AI-based image recognition becomes a standard feature in cameras, the demand for image sensors that can provide stable and high-quality imaging in conditions from bright to dark continues to grow.

The IMX908 employs STARVIS 3™, Sony’s proprietary LOFIC pixel technology developed for security cameras. It enables nearly 20x the amount of saturated charge as conventional products and delivers an approximately 27% improvement in low-light performance, which makes for a dynamic range of 96 dB. Not using multiple exposures, the more common method for HDR imaging, this sensor also provides high dynamic range imaging with a single exposure to deliver high-definition images with fewer artifacts, even of scenes with moving subjects. Furthermore, Sony’s original pixel design has enabled all these features to be provided at the industry’s smallest LOFIC pixel size of 1.45 µm. By offering higher-quality 4K imaging even in high-contrast scenes and dark environments, the new product will contribute to improved recognition accuracy and multifunctionality in security cameras.

Curved large-format IR sensor

Paper link: https://opg.optica.org/oe/fulltext.cfm?uri=oe-34-4-6880

In a recently published paper in Optics Express titled "Highly curved large-format sensors for infrared imaging", O'Masta et al of HRL Laboratories LLC write:

A curved, rather than flat, photoreceptive surface requires fewer optical elements and enhances illumination and sensitivity uniformity for wide-field vision. While such designs are common in vertebrate eyes, creating manmade curved sensing surfaces using high-performance sensors has been technologically challenging. Here, we surpassed previous practices by manipulating the strain within a die using a ductile metal layer. This enabled scalability to large-format sensors, which are valuable for capturing wide viewing angles with high resolution. We showcased this methodology using two types of III-V compound semiconductor photodetectors for mid-wave infrared (MWIR) imaging. The radiometric response of a hybridized fanout chip curved to a solid angle of 0.24 sr – over 300% beyond the limit of standard methods – was evaluated. A fully imaging focal plane array curved to 0.11 sr exhibited >97% operability. This demonstration of a spherically curved, cryogenically cooled MWIR imaging sensor highlights the feasibility of curving sensors comprised of heterogeneous semiconductor layering, which are commonly used in infrared, visible, and ultraviolet imagers.

STMicro Nvidia collab

STMicroelectronics accelerates global adoption and market growth of Physical AI with NVIDIA
 
 STMicroelectronics to integrate ST sensors, microcontrollers, and motor control solutions with NVIDIA robotics ecosystem to help developers design, train, and deploy humanoid robots and other physical AI systems with higher efficiency, reliability, and scalability
 First steps with integration of Leopard Imaging stereo depth camera enabled by ST with the NVIDIA Holoscan Sensor Bridge, and the addition of the high-fidelity sim-to-real model of ST IMU in NVIDIA Isaac Sim ecosystem
 
STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, today announced the acceleration of global development and adoption of physical AI systems, including humanoid, industrial, service and healthcare robots. ST is integrating its comprehensive portfolio for advanced robotics, into the reference set of components compatible with the NVIDIA Holoscan Sensor Bridge (HSB). In parallel, high-fidelity NVIDIA Isaac Sim models of ST components are being integrated into both companies’ robotics ecosystems to support faster, more accurate sim-to-real research and development. The first deliverables available to developers today include the integration of Leopard’s depth camera enabled by ST with the NVIDIA HSB and the high-fidelity model of an ST IMU into NVIDIA’s Isaac Sim ecosystem.
 
“ST is well engaged within the robotics community, providing robust support and a well-established ecosystem,” said Rino Peruzzi, Executive Vice President, Sales & Marketing, Americas & Global Key Account Organization at STMicroelectronics. “Our collaboration with NVIDIA aims to unleash the next wave of cutting-edge robotics innovation with developer and customer experience streamlined at every step, from the inception of AI algorithms to the seamless integration of sensors and actuators. This will accelerate the evolution of sophisticated AI-driven physical platforms.”
 
“Accelerating the development of next-generation autonomous systems requires high-fidelity simulation and seamless hardware integration to bridge the gap between virtual training and real-world deployment,” said Deepu Talla, Vice President of Robotics and Edge AI at NVIDIA. “The integration of STMicroelectronics’ sensor and actuator technologies with NVIDIA Isaac Sim, Holoscan Sensor Bridge and Jetson platforms provides developers with a unified foundation to build, simulate and deploy physical AI at scale.”
 
Simplifying sensor and actuator integration with the Holoscan Sensor Bridge
 
With the NVIDIA HSB, developers can unify, standardize, synchronize, and streamline data acquisition and logging from multiple ST sensors and actuators, a critical foundation for building high fidelity NVIDIA Isaac models, accelerating learning, and minimizing the sim to real gap.
 
The goal is to simplify the process of connecting ST sensors and actuators to NVIDIA Jetson platforms through pre-integrated solutions for the combination of STM32 MCUs, advanced sensors (including IMUs, imagers, and ToF devices) and motor‑control solutions, particularly for humanoid robot designs. Leopard Imaging’s stereo depth camera for robots is the perfect example. Using ST imaging, depth and motion-sensing technologies, it is expected to support a broad wave of designs across Physical AI OEMs, academic research groups and the industrial robotics community.
 
Reducing cost, complexity challenges with high-fidelity modeling for Omniverse Isaac
 
Advanced robotics developers face high development costs, in addition to modeling challenges. High‑fidelity simulations with extensive randomization demand substantial GPU and CPU resources and large datasets. Selecting which parameters to randomize, and over what ranges, requires deep domain expertise. Poor choices can result in unrealistic scenarios or inefficient training. Finally, excessive variability can confuse models, slow convergence, and degrade real‑world performance when randomization no longer reflects plausible conditions.
 
ST and NVIDIA’s objective is to provide accurate, hardware-calibrated models for the comprehensive portfolio of ST components matching the requirements of advanced robotics. Following the availability of the first model of an IMU, ST is working to bring developers models of ToF sensors, actuators and other ICs derived from benchmark data collected on real ST hardware, using ST tools to capture accurate parameters and realistic behavior, resulting in models optimized to NVIDIA’s Isaac Sim ecosystem. NVIDIA HSB is being integrated into ST’s toolchain collaboratively.
 
As a result, ST and NVIDIA envision that more accurate models will significantly improve robot learning. With models that closely mirror real-world device behavior, robots can learn from simulations that better reflect actual conditions, shortening training cycles and lowering the cost of building and refining humanoid robotics applications.

Pointcloud's 4D FMCW lidar paper published in Nature

Settembrini et al from Pointcloud GmbH (Zürich, Switzerland) published a paper titled "A large-scale coherent 4D imaging sensor" in Nature magazine.

Link: https://www.nature.com/articles/s41586-026-10183-6 

Abstract: Detailed and accurate 3D mapping of dynamic environments is essential for machines to interface with their surroundings and for human–machine interaction. Although considerable effort has been made to create the equivalent of the complementary metal–oxide–semiconductor (CMOS) image sensor for the 3D world, scalable, high-performance, reliable solutions have proven elusive. Focal plane array (FPA) sensors using frequency-modulated continuous-wave (FMCW) light detection and ranging (LiDAR) have shown potential to meet all of these requirements and also provide direct measurement of radial velocity as a fourth dimension. Previous demonstrations, although promising, have not achieved the simultaneous scale and performance required by commercial applications. Here we present a large-scale, coherent LiDAR FPA enabled by comprehensive chip-scale optoelectronic integration. A 4D imaging camera is built around the FPA and used to acquire point clouds. At the core is a 352 × 176-pixel 2D FMCW LiDAR FPA comprising more than 0.6 million photonic components, all integrated on-chip together with their associated electronics. This represents a five times increase in pixel count with respect to previous demonstrations. The pixel architecture combines the outbound and inbound optical paths within the pixel in a monostatic configuration, together with coherent detectors and electronics. Frequency-modulated light is directed sequentially to groups of pixels by in-plane thermo-optic switches with integrated electronics for driving and calibration. An integrated serial digital interface controls both optical switching and readout synchronously. Point clouds of objects ranging from 4 to 65 m with per-pixel integration time compatible with frame rates from 3 to 15 frames per second (fps) are shown. This result demonstrates the capabilities of FMCW LiDAR FPA sensors as enablers of ubiquitous, low-cost, compact coherent 4D imaging cameras.
