Sphere Studios’ Big Sky Cinema Camera Features an Insane 18K Sensor

Sphere Studios has developed a brand new type of cinema camera called The Big Sky. It features a single 316-megapixel HDR image sensor that the company says is a 40x resolution increase over existing 4K cameras and PetaPixel was given an exclusive look at the incredible technology.

 


 

Those who have visited Las Vegas in the last few years may have noticed the construction of a giant sphere building near the Venetian Hotel. Set to open in the fall of 2023, the Sphere Entertainment Co has boasted that this new facility will provide “immersive experiences at an unparalleled scale” featuring a 580,000 square-foot LED display and the largest LED screen on Earth.

As PetaPixel covered last fall, the venue will house the world’s highest resolution LED screen: a 160,000 square-foot display plane that will wrap up, over, and behind the audience at a resolution over 80 times that of a high-definition television with approximately 17,500 seats and a scalable capacity up to 20,000 guests. While the facility for viewing these immersive experiences sounds impressive on its own, it leaves one wondering what kind of cameras and equipment are needed to capture the content that gets played there.

The company has said “an innovative new camera system developed internally that sets a new bar for Image fidelity, eclipsing all current cinematic cameras with unparalleled edge-to-edge sharpness” — a very bold claim. While on paper it doesn’t seem much different from any other camera manufactures claims about their next-gen system, spending time with the new system in person and seeing what it is capable of paints an entirely different picture that honestly has to be seen to be believed.

“Sphere Studios is not only creating content, but also technology that is truly transformative,” says David Dibble, Chief Executive Officer of MSG Ventures, a division of Sphere Entertainment focused on developing advanced technologies for live entertainment.

“Sphere in Las Vegas is an experiential medium featuring an LED display, sound system and 4D technologies that require a completely new and innovative approach to filmmaking. We created Big Sky – the most advanced camera system in the world – not only because we could, but out of innovative necessity. This was the only way we could bring to life the vision of our filmmakers, artists, and collaborators for Sphere.”

According to the company, the new Big Sky camera system “is a groundbreaking ultra-high-resolution camera system and custom content creation tool that was developed in-house at Sphere Studios to capture stunning video for the world’s highest resolution screen at Sphere. Every aspect of Big Sky represents a significant advancement on current state-of-the-art cinema camera systems, including the largest single sensor in commercial use capable of capturing incredibly detailed, large-format images.”

The Big Sky features an “18K by 18K” (or 18K Square Format) custom image sensor which absolutely dwarfs current full frame and large format systems. When paired with the Big Sky’s single-lens system –which the company boasts is the world’s sharpest cinematic lens — it can achieve the extreme optical requirements necessary to match Sphere’s 16K by 16K immersive display plane from edge to edge.

Currently the camera has two primary lens designs: a 150-degree field of view which is true to the view of the sphere where the content will be projected, and a 165-degree field of view which is designed for “overshoot and stabilization” particularly useful in filming situations where the camera is in rapid motion or on an aircraft with a lot of vibrations (ie a helicopter).

The Big Sky features a single 316-megapixel, 3-inch by 3-inch HDR image sensor that the company says is a 40x resolution increase over existing 4K cameras and 160x over HD cameras. In addition to its massive sensor size, the camera is capable of capturing 10-bit footage at 120 frames per second (FPS) in the 18K square format as well as 60 FPS at 12-bit.

“With underwater and other lenses currently in development, as well as the ability to use existing medium format lenses, Sphere Studios is giving immersive content creators all the tools necessary to create extraordinary content for Sphere,” the company says.

Since the media captured by the Big Sky camera is massive, it requires some substantial processing power as well as some objectively obscene amounts of storage solutions. As such, just like the lenses, housings (including underwater and aerial gimbals), and camera, the entire media recorder infrastructure was designed and built entirely in-house to precisely meet the company’s needs.

According to the engineering team at Sphere, “the Big Sky camera creates a 500 gigabit per second pipe off the camera with 400 gigabit of fiber between the camera head and the media recorder. The media recorder itself is currently capable of recording 30 gigabytes of data per second (sustained) with each media magazine containing 32 terabytes and holds approximately 17 minutes of footage.”
The company says the media recorder is capable of handling 600 gigabits per second of network connectivity, as well as built-in media duplication, to accelerate and simplify on-set and post-production workflows. This allows their creative team to swap out drives and continue shooting for as long as they need.

Basically, as long as they have power and extra media magazines, they can run the camera pretty much all day without any issues. I did ask the team about overheating and heat dissipation of the massive system, and they went into great detail about how the entire system has been designed with a sort of internal “chimney” that maintained airflow through the camera ensuring it would not overheat and can keep running even in some of the craziest weather scenarios ranging from being completely underwater to surrounded by dust storms without incident.

What’s even more impressive is the camera can run completely separate from this recording technology as long as it is connected through its cable system, this includes distances of up to a reported mile away.

Since the entire system was built in-house, the team at Sphere Studios had to build their own image processing software specifically for Big Sky that utilizes GPU-accelerated RAW processing to make the workflows of capturing and delivering the content to the Sphere screen practical and efficient. Through the use of proxy editing, a standard laptop can be used, connected to the custom media decks to view and edit the footage with practically zero lag.

Why Is This A Big Deal?
While the specs on paper are unarguably mind-boggling, it’s practically impossible to express just how impressive the footage and experience is to see it captured and presented on the sphere screens it was meant for.

The good news is that PetaPixel was invited to the Los Angeles division for a private tour and demonstration of the groundbreaking technology so we could see it all firsthand and not just go off of the press release. I wasn’t able to take photos or video myself — the images and video in this write-up were provided by the Sphere Studios team — but I can confirm that this technology is wildly impressive and will definitely change the filmmaking industry in the coming years.

When showing me the initial concepts and design mock-ups, the team didn’t think of the content they deliver as simply footage, but rather “experiential storytelling” and after having experienced it for myself, I wholeheartedly agree.

During my tour of the facility, I got to see the camera first hand, look at live footage and rendering in real-time, as well as see some test images and video footage, including some scenes that may make it into “Postcard from Earth” which is the first experience being revealed at the Sphere in Las Vegas this fall that has footage captured from all over the planet that should give viewers a truly unique perspective of what the planet and this new camera system has to offer.

On top of the absolutely massive camera, the system they have developed to “experience” the footage includes haptic seating, true personal-headphone level sound without the headphones from any seat, as well as a revolutionary “environmental” system that can help viewers truly feel the environment they are watching with changing temperatures, familiar scents, and even a cool breeze.
“Sphere Studios is not only creating content, but also technology that is truly transformative,” says Dibble.

“Sphere in Las Vegas is an experiential medium featuring an LED display, sound system and 4D technologies that require a completely new and innovative approach to filmmaking. We created Big Sky – the most advanced camera system in the world – not only because we could, but out of innovative necessity. This was the only way we could bring to life the vision of our filmmakers, artists, and collaborators for Sphere.”

Something worth noting is all of this came to life effectively in just a few short years. The camera started out as an “array” of existing 8K cameras mounted in a massive custom housing. This created an entirely new series of challenges when processing and rendering the massive visuals, which lead to the development of the Big Sky single-lens camera itself, which is currently in its version 2.5 stage of development.

Each generation has made the system more compact and efficient also. The original system was over 100 pounds with the current (v2) weighing a little over 60 pounds, with the next generation lens being developed bringing the system under 30 pounds.

Equally impressive was the amount of noise the camera made, which is to say it was practically silent in operation. Even with the cooling system running it was as quiet or even quieter than most existing 8K systems in the cinematic world — comparing it to an IMAX wouldn’t even be fair… to the IMAX.

The Big Sky cameras are not up for sale (yet) but they are meeting with film companies and filmmakers to find ways to bring the technology to the home-entertainment world. A discussion we had on-site revolved around gimbals mounted on helicopters, airplanes, and automobiles and how those systems, even “the best” still experience some jitter/vibration which is often stabilized which causes the footage to be cropped in.


The technology built for Big Sky helps eliminate a massive percentage of this vibration, and even without it, the sheer amount of resolution the camera offers can provide a ton of space for post-production stabilization. This alone could be a game changer for Hollywood when capturing aerial and “chase scene” footage from vehicles allowing for even more detail than ever before.

Big Sky’s premiere experience at Sphere in Las Vegas is set to open on September 29 with the first of 25 concerts by U2, as well as many other film and live event projects that will be announced soon.

VoxelSensors Debuts the Global Premiere of Revolutionary Switching Pixels® Active Event Sensor Evaluation Kit for 3D Perception to Seamlessly Blend the Physical and Digital Worlds

BRUSSELS, Belgium, May 29, 2023 (GLOBE NEWSWIRE) -- VoxelSensors is to reveal its innovative 3D Perception technology, the Switching Pixels® Active Event Sensor (SPAES), and globally premiere the related Andromeda Evaluation Kit at AWE USA 2023. Experience this breakthrough technology from May 31 to June 2 at AWE booth #914 in Santa Clara (California, USA).

VoxelSensors’ Switching Pixels® Active Event Sensor is a novel category of ultra-low power and ultra-low latency 3D perception sensors for Extended Reality (XR) to seamlessly blend the physical and digital worlds.

Extended Reality device manufacturers require low power consumption and low latency 3D Perception technology to flawlessly blend the physical and digital worlds and unlock the true potential of immersive experiences. VoxelSensors’ patented Switching Pixels® Active Event Sensor technology has uniquely resolved these significant challenges and is the world’s first solution that has achieved a threshold of less than 10 milliwatts in terms of power consumption, combined with less than 5 milliseconds of latency. Furthermore, this is possible while being resistant to indoor and outdoor lighting at distances over 5 meters and being immune to crosstalk.

This breakthrough technology offers an alternative to traditional 3D sensors, eliminating the need for slow frames. It sends 3D data points in real-time serially to the device and application at nanosecond refresh rates. Designed for efficiency, SPAES delivers the lowest latency for perception applications at minimal power consumption addressing previously unmet needs such as precise segmentation, spatial mapping, anchoring, and natural interaction.

“SPAES disrupts the standard in 3D Perception,” says Christian Mourad, co-founder and VP of Engineering at VoxelSensors. “The Andromeda Evaluation Kit, available for the selected OEMs and integrators in the summer of 2023, demonstrates our commitment to advancing XR/AR/MR and VR applications.

IISW Summary from TechInsights

Image Sensors World        Go to the original article...

The International Image Sensor Workshop 2023 offered an excellent overview of sensors past, present and future

John-Scott Thomas PhD, TechInsights (Image Sensor Subject Matter Expert)

After a long hiatus courtesy of COVID, the International Image Sensor Workshop (IISW) 2023 was held in-person at the charming Crieff Hydro Hotel in the highlands of Scotland from May 21-25. With over two hundred attendees by my count, the workshop presented a lively and informative forum for image sensor devices past, present and future. TechInsights was honored to open the meeting with a presentation on the state-of-the-art in small pixel (mobile) devices. With fifteen minutes available only the briefest overview was possible, and we focused on the technologies that enable the transition to the 0.56 micron pixel pitch (Samsung and OmniVision) and 0.70 micron (Sony) pixel pitch. You can read the TechInsights paper here.

Sony (presented by Masatak Sugimoto) then described the structure of a two-layer image sensor where the photodiode and transfer gate of the pixel is placed on one semiconductor layer and the reset, source-follower, and select transistors are placed on a lower layer. This structure allows optimization of the two layers with different processes for each and pushes the current limits of hybrid bonding. This was all the more interesting as TechInsights located a Sony sensor using 2-layer transistor pixels (in the Xperia 1V smartphone) as the workshop began. We’ll have plenty more analysis in our channels for this world-first device. Samsung (Sungsoo Choi) and OmniVision (Chung Yung Ai) then presented further technical details of the 0.56 micron pixels the two companies are producing. The first session was rounded out with another Samsung (Minho Kwon) presentation on a switchable resolution sensor and an onsemi (Vladi Korobov) surveillance sensor optimized for low light and Near Infra-red (NIR).
Following sessions discussed noise and pixel design. The Automotive session focused on High Dynamic Range, and a presentation by Manual Innocent (onsemi) shared an impressive video clip showing an automotive camera emerging from a dark tunnel to bright sunlight with excellent image quality using  a 150 dB sensor. Automotive cameras will be a high growth segment and are particularly suited to sensing outside the visible spectrum. More exotic applications included X-ray sensors, Ultraviolet and Short Wavelength Infrared sensors, discussed later in the conference. The final two sessions covered Time of Flight and SPAD sensors; already used in mobile applications, these are promising technologies in surveillance and automotive devices.

Of particular note were the discussions about digital image processing, artificial intelligence, and cybersecurity. There was general agreement that future devices will have much more digital processing included in the stacked Image Signal Processor, although many attendees felt most of the image processing should be performed on the applications processor when possible since this device uses a more advanced process node. The younger attendees showed a significant interest in digital image processing through their presentations, posters, and questions; a sign of things to come no doubt. This was highlighted by the two invited speakers. Charles Bouman (Purdue University) provided an overview of the abilities of computational imaging and emphasized the need for more dialogue between the image sensing community and the digital processing community. Jerome Chossat (STMicroelectronics) presented trends analysis clearly showing there will be plenty of computational power available in future stacked image sensors.

A banquet concluded the workshop – complete with a starlit (electric, of course) hall, bagpipes and kilts. Neil Dutton (STMicroelectronics) opened the evening and in general provided excellent management of the sessions. Boyd Fowler (OmniVision) presented awards to the best papers and posters, and finally three awards to seasoned veterans of the image sensor world. John Tower was recognized for his contributions to Image Sensor publications, Takeharu Goji Etoh for his sustained contributions to High Speed Cameras and Edoardo Charbon for imaging using SPAD arrays. Edoardo showcased an amazing video clip of a light pulse travelling through air and bouncing from mirrors. If you haven’t seen this before, you really should check it out.

Much of the value at a workshop happens with the conversations that take place out of session and at the many social events happening beyond formalities. This event reminded me of the importance of in-person meetings. TechInsights will continue to participate and watch this exciting field for further innovation. The International Image Sensor Society intends to provide all of the workshop papers on their website in the next few weeks.

Compressive diffuse correlation spectroscopy with SPADs

Image Sensors World        Go to the original article...

Optics.org news article https://optics.org/news/14/5/9 about recently published work from U. Edinburgh. https://doi.org/10.1117/1.JBO.28.5.057001

University of Edinburgh improves diffuse imaging of blood flow

10 May 2023
New data processing approach could relieve bottleneck for speckle techniques in clinics.

Diffuse correlation spectroscopy (DCS) can assess blood flow non-invasively, by analyzing diffused light returning from illuminated areas of tissue and detecting the speckled spectral signals of blood cells in motion.

The potential impact of DCS was recognized in a 2022 SPIE report, which concluded that "an exciting era of technology transfer is emerging as research groups have spun-out well-established, early-stage startup ventures intending to commercialize DCS for clinical use."

The SPIE report identified the increasing availability of advanced single-photon avalanche diode (SPAD) detectors as a key factor in the current rise of DCS techniques. However, those same detectors have introduced a potential new hurdle, caused by the increased data handling requirements of diffuse spectroscopic methods.

The extremely high data rates of modern SPAD cameras can exceed the maximum data transfer rates of commonly used communication protocols, a bottleneck that has limited the scalability of SPAD cameras to higher pixel resolutions and hindered the development of better multispeckle DCS techniques.

A project based at the University of Edinburgh and funded by Meta Platforms has now demonstrated a new data compression scheme that could improve the sensitivity and usability of multispeckle DCS instruments.

The study, published in Journal of Biomedical Optics, describes a novel data compression scheme in which most calculations involving SPAD data are performed directly on a commercial programmable circuit called a field-programmable gate array (FPGA). This alleviates the previous need for high computational power and extremely fast data transfer rates between the DSC system and the host system upon which the data is visualized, according to the project.

Clearer views of the brain
If the key part of the computational analysis, a per-pixel calculation termed the autocorrelation function, takes place locally on the FPGA, then a higher imaging frame rate can be maintained than is possible with existing hardware autocorrelators.

To test this approach, the Edinburgh project constructed a large array SPAD camera in which 128 linear autocorrelators were embedded in an FPGA integrated circuit. Packaged into a camera module christened Quanticam, this was able to calculate 12,288 channels of data and compute the ensemble autocorrelation function from 192 x 64 pixels of DCS data in real time.

"Our proposed system achieved a significant gain in the signal-to-noise ratio, which is 110 times higher than that possible on a single-speckle DSC implementation and 3 times higher than other state-of-the-art multispeckle DSC systems," commented Robert Henderson from the University of Edinburgh.

If FPGA-based designs can help researchers adopt SPAD arrays with high pixel resolution but without the data processing load currently involved, then SPAD cameras could become more widely adopted in the biomedical research community. This would expand the horizons of multispeckle DCS to more areas of biomedical research, including the imaging of cerebral blood dynamics.

"Intense research effort in SPAD camera development is currently ongoing to improve camera capabilities toward even larger pixel count, shorter exposure time and higher detection probability," said the project in its paper. "Soon we should expect high-performance SPAD cameras with FPGA-embedded or even on-chip computing that could surpass the multispeckle DCS requirements for noninvasive detection of local brain activation."

PCH-EM Algorithm for DSERN characterization

Image Sensors World        Go to the original article...

Hendrickson et al. have posted two new pre-prints on deep sub-electron read noise (DSERN) characterization. This new algorithm called PCH-EM is used to extract key performance parameters of sensors with sub-electron read noise through a custom implementation of the Expectation Maximization (EM) algorithm. It shows a dramatic improvement over the traditional Photon Transfer (PT) method in the sub-electron noise regime. The authors have some extensions and improvements of the method coming soon as well.

The first pre-print titled "Photon Counting Histogram Expectation Maximization Algorithm for Characterization of Deep Sub-Electron Read Noise Sensors" presents the theory behind their approach.

Abstract: We develop a novel algorithm for characterizing Deep Sub-Electron Read Noise (DSERN) image sensors. This algorithm is able to simultaneously compute maximum likelihood estimates of quanta exposure, conversion gain, bias, and read noise of DSERN pixels from a single sample of data with less uncertainty than the traditional photon transfer method. Methods for estimating the starting point of the algorithm are also provided to allow for automated analysis. Demonstration through Monte Carlo numerical experiments are carried out to show the effectiveness of the proposed technique. In support of the reproducible research effort, all of the simulation and analysis tools developed are available on the MathWorks file exchange.

The second pre-print titled "Experimental Verification of PCH-EM Algorithm for Characterizing DSERN Image Sensors" presents an application of the PCH-EM algorithm to quanta image sensors.

Abstract: The Photon Counting Histogram Expectation Maximization (PCH-EM) algorithm has recently been reported as a candidate method for the characterization of Deep Sub-Electron Read Noise (DSERN) image sensors. This work describes a comprehensive demonstration of the PCH-EM algorithm applied to a DSERN capable quanta image sensor. The results show that PCH-EM is able to characterize DSERN pixels for a large span of quanta exposure and read noise values. The per-pixel characterization results of the sensor are combined with the proposed Photon Counting Distribution (PCD) model to demonstrate the ability of PCH-EM to predict the ensemble distribution of the device. The agreement between experimental observations and model predictions demonstrates both the applicability of the PCD model in the DSERN regime as well as the ability of the PCH-EM algorithm to accurately estimate the underlying model parameters.
