Panasonic Develops Industry’s-First 8K High-Resolution, High-Performance Global Shutter Technology using Organic-Photoconductive-Film CMOS Image Sensor

Osaka Japan, - Panasonic Corporation today announced that it has developed a new technology which realizes 8K high-resolution (36M pixels), 60fps framerate, 450k high-saturation electrons and global shutter [1] imaging with sensitivity modulation function simultaneously, using a CMOS image sensor with an organic photoconductive film (OPF). In this OPF CMOS image sensor, the photoelectric-conversion part and the circuit part are independent. By utilizing this OPF CMOS image sensor's unique structure, we have been able to newly develop and incorporate high-speed noise cancellation technology and high saturation technology in the circuit part. And, by using this OPF CMOS image sensor's unique sensitivity control function to vary the voltage applied to the OPF, we realize global shutter function. The technology that simultaneously achieves these performances is the industry's first*1.

With the technology, it is possible to capture images at 8K resolution, even in high contrast scenes, such as a field under strong sunlight and shaded spectator seats under a stadium roof. Moreover, by utilizing the global shutter function that enables simultaneous image capture by all pixels, it is expected to be able to capture moving objects instantaneously without distortion, be utilized for multi viewpoint cameras (performing multi-view synchronized imaging using plural cameras) and used in fields requiring high-speed and high-resolution, such as machine vision and ITS monitoring. In addition, conventionally, even in scenes where it was necessary to utilize different ND filters [2] according to capturing conditions, the technology realizes a new electronically-controlled variable ND filter function which enables stepless adjustment of the OPF sensitivity [3] merely by controlling the voltage applied to the OPF.

The new technology has the following advantages.

  1. 8K resolution, 60fps framerate, 450k saturation electrons and global shutter function are realized simultaneously.
  2. Switching between high sensitivity mode and high saturation mode is possible using gain switching function.
  3. The ND filter function can be realized steplessly by controlling the voltage applied to the OPF.

This Development is based on the following technologies

  1. "OPF CMOS image sensor design technology", in that, the photoelectric-conversion part and the circuit part can be designed independently.
  2. "In-pixel capacitive coupled noise cancellation technique" which can suppress pixel reset noise at high speed even at high resolution
  3. "In-pixel gain switching technology" that can achieve high saturation characteristics
  4. "Voltage controlled sensitivity modulation technology" that can adjust the sensitivity by changing the voltage applied to the OPF.

Panasonic holds 135 Japanese patents and 83 overseas patents (including pending) related to this technology.

Panasonic will present some of these technologies at the international academic conference: ISSCC (International Solid-State Circuit Conference) 2018 which will be held in San Francisco on February 11 - 15, 2018.

More on the Technology

"OPF CMOS image sensor design technology", in that, the photoelectric-conversion part and the circuit part can be designed independently.

The OPF CMOS image sensor has a unique structure, in which, the OPF performs a photoelectric conversion and the circuit area performs charge storage and signal readout functions completely independently. Using this OPF CMOS image sensor structure, we developed high-speed noise cancellation technology and high saturation technology in the circuit area which has a large available space. As a result, it is possible to realize simultaneously 8K resolution, 60fps framerate readout, wide dynamic range [4] (by achieving a high saturation level) and global shutter function, which are normally traded off.

"In-pixel capacitive coupled noise cancellation technique" which can suppress pixel reset noise at high speed even at high resolution

Because the OPF CMOS image sensor has a structure in which the OPF and the charge storage part are connected by metal plugs, accumulated charges cannot be completely read out. Therefore, there is a problem that it is affected by reset noise at the time of resetting the pixel (signal charge storage node). And, in a high-resolution sensor, such as an 8K sensor, it is necessary to drive large loads exceeding 4000 pixels aligned in the vertical direction at the same time as the time of noise cancellation, and therefore, the long time it takes to suppress noise is a problem. So, we developed a new structure that cancels pixel reset noise at high speed, even when high resolution pixels have to be driven, by using Panasonic's original semiconductor device technology and the newly developed "in-pixel capacitive coupled noise canceller". In this structure, the reset noise is suppressed at high speed by using the negative feedback loop provided for each pixel.

"In-pixel gain switching technology" that can achieve high saturation characteristics

In the OPF CMOS image sensor, by incorporating a large capacitor in the circuit part with a large available area, it is possible to realize both high sensitivity mode and high saturation mode with the same pixel structure merely by switching modes from the camera system. In the high sensitivity mode, it is possible to capture data up to a light intensity of 4.5k electrons with high sensitivity. Furthermore, by switching to the high saturation mode, it is possible to capture data up to a light intensity of 450k electrons. In this way, since the high saturation mode can capture up to 10 times the high sensitivity mode, it is possible to clearly display the fine winding structure of the lamp filaments, in which bright part gradation cannot be expressed, because it becomes overexposure in high sensitivity mode, as shown in Fig. 3 (a). Even in a scene with high contrast, such as shown in Fig. 5, from the facial expression of the person in the shadow of the stadium roof to the blue sky and clouds during a mid-summer day, and such as shown in Fig. 6, from the dimly lit room to the sunny garden, it will be possible to capture brilliant images without overexposure or underexposure.

"Voltage controlled sensitivity modulation technology" that can adjust the sensitivity by changing the voltage applied to the OPF.

The OPF CMOS image sensor can change the sensitivity of the OPF simply by controlling the voltage applied to the OPF. By utilizing this function, we can realize the following functions which could not be realized with conventional silicon image sensors.

Sensitivity Modulation Example 1: Global shutter function which can capture all pixels simultaneously at 8K resolution

By controlling ON / OFF of the voltage applied to the OPF and controlling the sensitivity of the OPF, we realize the "global shutter function" capable of imaging all pixels at the same time, even driving a large number of pixels like the 8K sensor. By capturing with the global shutter function, as shown in Fig. 3 (b), the letters on the rotating body are read sharply without distortion. In addition, as shown in Fig. 7, even at the time of high speed moving object capturing, such as when driving on a highway or at industrial inspection, capturing without distortion becomes possible.

In the conventional global shutter type silicon image sensor, it is necessary to add new elements such as transfer circuits and charge storage capacitors in order to accumulate charges simultaneously in all pixels. As a result, the area of the photodiode and that of the additional circuits must compete for space, there is a problem that the pixel size cannot be reduced and the amount of saturation electrons cannot be increased. On the other hand, in the OPF CMOS image sensor, since there is no need for additional elements, it is possible to realize small cell, high resolution sensors, and by incorporating large capacitors in the circuit part with a large available area, accurate imaging with no distortion from dark scenes to extremely bright scenes is possible. For example, as shown in Fig. 9, with the OPF CMOS image sensor, when buildings are photographed while panning [5] at high speed, even in scenes with high contrast like a bright sky and dark windows, it is possible to acquire image data maintaining all gradations of the whole area without distortion.

Sensitivity Modulation Example 2: "Electrical ND Filter Technology" which can change sensitivity continuously and steplessly

Conventionally it has been necessary to provide a plurality of ND filters according to photographing conditions and change them many times. On the other hand, in the OPF CMOS image sensor, merely by controlling the voltage applied to the OPF (VITO in Fig. 8) and changing the sensitivity of the OPF to the desired value, it is possible to electrically implement the ND filter function. By using this function, it becomes possible to simplify the photographic equipment and continuously, steplessly control the sensitivity which could not be realized with a conventional silicon sensor. Therefore, the possibility of capturing according to the scene is expanded.

In the future, we will utilize this OPF CMOS image sensor technology in various applications such as broadcasting cameras, surveillance cameras, industrial inspection cameras, automotive cameras, etc., and will contribute to realize high resolution, high speed and high precision imaging and sensing functions.

New Sony sensors will have much more ADCs, thanks for stacking Tue, 13 Feb 2018 05:42:31 -0700 Vitaliy_Kiselev 18995@/talks/discussions

Sony Corporation today announced that it has developed a 1.46 effective megapixel back-illuminated CMOS image sensor equipped with a Global Shutter function*1. The newly developed pixel-parallel analog-to-digital converters provide the function to instantly convert the analog signal from all pixels, simultaneously exposed, to a digital signal in parallel. This new technology was announced at the International Solid-State Circuits Conference (ISSCC) on February 11, 2018 in San Francisco in the United States.


CMOS image sensors using the conventional column A/D conversion method read out the photoelectrically converted analog signals from pixels row by row, which results in image distortion (focal plane distortion) caused by the time shift due to the row-by-row readout.

The new Sony sensor comes with newly developed low-current, compact A/D converters positioned beneath each pixel. These A/D converters instantly convert the analog signal from all the simultaneously exposed pixels in parallel to a digital signal to temporarily store it in digital memory. This architecture eliminates focal plane distortion due to readout time shift, making it possible to provide a Global Shutter function1, an industry-first for a high-sensitivity back-illuminated CMOS sensor with pixel-parallel A/D Converter with more than one megapixel3.

The inclusion of nearly 1,000 times as many A/D converters compared to the traditional column A/D conversion method2 means an increased demand for current. Sony addressed this issue by developing a compact 14-bit A/D converter which boasts the industry’s best performance4 in low-current operation.

Both the A/D converter and digital memory spaces are secured in a stacked configuration with these elements integrated into the bottom chip. The connection between each pixel on the top chip uses Cu-Cu (copper-copper) connection*5, a technology that Sony put into mass production as a world-first in January 2016.

In addition, a newly developed data transfer mechanism is implemented into the sensor to enable the high-speed massively parallel readout data required for the A/D conversion process.

Main Features

Global Shutter function achieved in a high-sensitivity back-illuminated CMOS image sensor by using the following key technologies: Low-current, compact pixel-parallel A/D converter. In order to curtail power consumption, the new converter uses comparators that operate with subthreshold currents, resulting in the industry’s best-performing4, low current, compact 14-bit A/D converter. This overcomes the issue of the increased demand for current due to the inclusion of nearly 1,000 times as many A/D converters in comparison with the traditional column A/D conversion method2.

Cu-Cu (copper-copper) connection
To achieve the parallel A/D conversion for all pixels, Sony has developed a technology which makes it possible to include approximately three million Cu-Cu (copper-copper) connections*5 in one sensor. The Cu-Cu connection provides electrical continuity between the pixel and logic substrate, while securing space for implementing as many as 1.46 million A/D converters, the same number as the effective megapixels, as well as the digital memory.

High-speed data transfer construction
Sony has developed a new readout circuit to support the massively parallel digital signal transfer required in the A/D conversion process using 1.46 million A/D converters, making it possible to read and write all the pixel signals at high speed.

Canon - cry from the dying beast Tue, 08 Sep 2015 07:26:56 -0600 Vitaliy_Kiselev 13675@/talks/discussions

Canon Inc. announced today that it is developing a Cinema EOS System 8K camera and professional-use 8K reference display that will support the production of next-generation 8K video content, along with a still-image single-lens reflex camera equipped with a CMOS sensor featuring approximately 120 million effective pixels. Through the Company’s proprietary imaging technologies, Canon provides still and video input and output devices that will contribute to the development of imaging culture.

Canon, as a leading company in the field of imaging technology, conducts research and development into devices designed to support cinema and video production with the aim of expanding the boundaries of visual expression. Through the further enhancement of the Cinema EOS System 8K camera and professional-use 8K reference display under development, Canon aims to contribute to smooth production workflows, facilitating not only the input and output of 8K video content, but also such processes as 8K to 4K down-conversion and 4K cropping.

The Cinema EOS System 8K camera being developed will be equipped with a Canon Super 35 mm-equivalent CMOS sensor that makes possible high-resolution 8,192 x 4,320 pixel (approximately 35.39 million effective pixels) imaging performance even at a frame rate of 60 frames per second with 13 stops1 of dynamic range and a richly expressive wide color gamut. Additionally, featuring a body size that realizes outstanding mobility and a design that delivers high levels of operability, along with an EF mount that offers compatibility with Canon’s extensive interchangeable EF lens lineup,2 the camera will support diverse shooting styles and means of visual expression.

Incorporating Canon image-processing technology, the ultra-high-resolution 8K reference display currently under development will achieve high brightness, high contrast (high dynamic range) and a wide color gamut. Additionally, with a pixel density exceeding 300 pixels per inch, a level approaching the limit of human visibility, the display will make possible ultra-realistic imaging that enables the reproduction of subtle changes in light that were previously not possible. Furthermore, when used in combination with the Cinema EOS System 8K camera, the display will be capable of conveying truly impressive levels of visual expression.

Featuring a resolution of approximately 120 effective megapixels, the SLR camera now being developed will incorporate a Canon-developed high-pixel-density CMOS sensor within the current EOS-series platform, which will realize compatibility with the Company’s diverse interchangeable EF lens lineup.3 The high-resolution images that the camera will be capable of producing will recreate the three-dimensional texture, feel and presence of subjects, making them appear as if they are really before one’s eyes. The camera will facilitate a level of resolution that is more than sufficient for enlarged poster-sized printout while also enabling images to be cropped and trimmed without sacrificing image resolution and clarity.

Foxconn to enter digital camera market Mon, 12 Feb 2018 07:21:41 -0700 Vitaliy_Kiselev 18988@/talks/discussions

Major iPhone assembler Hon Hai Precision Industry, better known as Foxconn Technology Group, said on Sunday that it plans to team up with premium camera maker RED Digital Cinema to make professional-quality and affordable film cameras for the general public, while expanding into the manufacture of semiconductors for displays and cameras.

Those moves come as the Taiwanese company is building facilities to make large-scale display panels in the U.S. and China. It is seeking new revenue sources to compensate for weakening smartphone demand. It wants to reduce its business dependence on Apple, which accounts for more than 50% of its sales. Foxconn assembles iPhone mobile phones and MacBook computers among other products for Apple, but profit margins are razor thin. The manufacture of more electronics equipment and components could improve the company's earnings.

"We will make cameras that will shoot professional-quality films in 8K resolution but at only a third of current prices and a third of current camera sizes," Foxconn Chairman Terry Gou told reporters in Taipei following the company's annual employee party before the Chinese New Year. 8K ultra-high definition resolution has become the benchmark standard for digital television and cinematography.

Gou said he is in talks with RED Digital Cinema, whose cameras are used in the filming of such hit films and TV shows as Transformers and Netflix's House of Cards, to form a joint venture or partnership to produce affordable cameras. A RED's 8K camera now sells for around $30,000.

Foxconn's move is part of an effort to build a corporate ecosystem related to displays and videos. Gou said his company is basing its strategy on the display manufacturing facilities it already operates and its 2016 acquisition of Sharp's semiconductor business, which will be expanded this year.

"Not only displays, Sharp controls important chip technologies for various image sensors that go into digital cameras and televisions. We will definitely make good use of them and make more of them," said Gou. "And we will make these [semiconductors] much more cheaply. That's our important goal and project for this year."

HDR - new marketing idea Sat, 09 Jan 2016 00:00:09 -0700 Vitaliy_Kiselev 14402@/talks/discussions 2016 is a year of HDR, as 2014 had been for basic 4K and 2015 had been for color gamut and quantum dots.

Current REC.709 televisions only display 33% of the actual amount of colours you can see and they are also limited to around 100 NITS of brightness (NITS are the unit used to measure brightness),

And this is that happens if you read too much marketing literature.

In reality most consumer TVs are not 100nits (and at retail demo rooms they are even more far from it). And they are NOT limited here.

Next thing people do not understand that sRGB color gamut is not so limiting due to fact that we see reflected light in nature and super saturated colors that is not included can be rarely seen in nature.

Next trap lies in complete misunderstanding on that dynamic range of reproduction device is (and replacing it in the head with dynamic range of camera).
Dolby lie comes from marketing proposal that limiting factor of consumer sets comes from maximum brightness, and it is just not true. While actual limiting factor now come from black level on LCD sets. And all modern quantum dots and so called "UltraHD Premium" marketing labels have nothing to do with it.

Real cure can come from OLED side, where black level is limited only by room reflected light. OLED also can be made with very wide gamut with ease. Main issue with them is... color degradation and burn in, especially with long time high brightness.

In reality that Dolby want to do now is to introduce premium theaters where they will check reference brightness level and try to keep it at acceptable level (saving on bulbs in theaters is very common business, as with brightness reduction very expensive bulbs work much longer) and also check quality of projectors and used screens to do not have washed out colors.

Sony New Management Structure Fri, 02 Feb 2018 03:48:15 -0700 Vitaliy_Kiselev 18919@/talks/discussions

Kenichiro Yoshida named as President and CEO effective April 1, 2018; Kazuo Hirai to become Chairman

Tokyo, February 2, 2018 — Sony Corporation (“Sony”) today announced that Kenichiro Yoshida, currently Director, Representative Corporate Executive Officer, Executive Deputy President and Chief Financial Officer, has been appointed as Director, Representative Corporate Executive Officer, President and Chief Executive Officer, effective April 1, 2018. Kazuo Hirai, currently Director, Representative Corporate Executive Officer, President and Chief Executive Officer, will become Director, Chairman, also effective April 1, 2018.

The above management transition was proposed by Mr. Hirai to the Sony Nominating Committee, and following deliberation by the Nominating Committee, was approved by the Sony Board of Directors at a Board meeting held earlier today.

Following this realignment, Sony will embark on its next mid-range corporate plan starting April 1 2018, under a new management structure led by Mr. Yoshida.

Comment from Kazuo Hirai
“Ever since my appointment as President and CEO in April 2012, I have stated that my mission is to ensure Sony continues to be a company that provides customers with kando – to move them emotionally – and inspires and fulfills their curiosity. To this end, I have dedicated myself to transforming the company and enhancing its profitability, and am very proud that now, in the third and final year of our current mid-range corporate plan, we are expecting to exceed our financial targets. And it excites me to hear more and more people enthuse that Sony is back again. As the company approaches a crucial juncture, when we will embark on a new mid-range plan, I consider this to be the ideal time to pass the baton of leadership to new management, for the future of Sony and also for myself to embark on a new chapter in my life. My successor, Kenichiro Yoshida, has supported me closely since returning to Sony in December 2013 , contributing extensively beyond his remit as CFO and acting as valuable confidant and business partner, as we took on the challenge of transforming Sony together. Mr. Yoshida combines a deeply strategic mindset with a relentless determination to achieve defined targets, and the ability to take a global viewpoint. I believe he possesses the breadth of experience and perspective, as well as the unwavering leadership qualities required to manage Sony’s diverse array of businesses, and as such is the ideal person to drive the company forward into the future. As Chairman, I will of course offer my full support to Mr. Yoshida and the new management team, and do all I can to facilitate a smooth transition and ensure their future success.”

Comment from Kenichiro Yoshida
“I am very grateful to Kazuo Hirai and the Sony Board for their trust and confidence in appointing me as Sony President and CEO, and at the same time feel a great sense of responsibility in taking on this vitally important role. Together with the outstanding talent we have across the Sony Group, I will aim to build on the business foundations established by Mr. Hirai, and execute further reform measures that enhance our competitiveness as a global enterprise, and enable us to realize long-term profit growth. My first priority will be to finalize our next mid-range corporate plan starting in April, together with our immediate business plan for the fiscal year 2018, and then move ahead swiftly with implementation. This is a hugely exciting time at Sony as we look to our future, and together with my management team I intend to determine the best path for us to move forward, and devote my full effort to creating a better Sony that captures the imagination of our many stakeholders around the world.”

Comment from Osamu Nagayama, Chairman of the Board and Chair of the Nominating Committee
“The Board is grateful to Kazuo Hirai for his outstanding contribution over the past six years, taking leadership of the company amidst an extremely challenging business environment in 2012, and making great progress in revitalizing Sony’s business. Given these achievements, we were initially surprised by his proposal to step down from the role of President and CEO, but over time and following extensive further discussions we ultimately reached a decision to respect his wishes. The Nominating Committee had been regularly discussing potential management succession plans, and after receiving the proposal from Mr. Hirai, we engaged in renewed discussion, leading to the conclusion that Mr. Yoshida would be the ideal candidate to succeed Mr. Hirai as Sony President and CEO, and lead Sony into the future. The Board also unanimously supported this proposal. Together with Mr. Hirai, the Board will offer their full support to Mr. Yoshida and his new management team, while also closely observing their progress from a shareholder perspective.”

EBay to stop using Paypal Thu, 01 Feb 2018 04:01:16 -0700 Vitaliy_Kiselev 18910@/talks/discussions

EBay said it will start processing payments globally using Dutch payments company Adyen, allowing its users to remain on the eBay website when checking out.

PayPal said eBay shoppers will still be able to select PayPal as a form of payment until at least July 2023. The news from eBay came as PayPal reported quarterly earnings that beat Wall Street estimates but gave a disappointing outlook for the first quarter. PayPal shares initially fell 5 percent after the release of the quarterly results.

The chief executive officer of PayPal, Dan Schulman, said on a call with analysts that the changing relationship with eBay was very “manageable” and that it was in line with PayPal’s new strategy.

EBay accounts for roughly 13 percent of total payments processed by PayPal.

Paypal processed $131 billion in payments in the fourth quarter, up 32 percent from a year earlier, and added 8.7 million active customers.

Xiaomi violated over 200 patents Thu, 01 Feb 2018 14:43:14 -0700 tonalt 18917@/talks/discussions The Chinese media was agog recently with news that Coolpad had sued Xiaomi before a Beijing court for patent infringement. Xiaomi had come out after that to deny the allegation and stated that it is yet to receive the court papers. The latest gist coming out of that story comes from Coolpad’s CEO Jiang Chao who revealed that Xiaomi’s infringement of its patents spans more than 200 patents. The CEO, however, stated that they decided to sue Xiaomi for just six out of the 200.

Jiang Chao hinted that the purpose of selecting just 6 out of the 200 patents that Xiaomi and others infringed pon was to enhance China’s awareness and protection of intellectual property rights. He particularly noted that Coolpad does not intend to take advantage of Xiaomi’s rising status. Jiang also revealed that Coolpad has more than 10,000 patents authorized only for use by Qualcomm, and are not licensed for use by third parties. He noted that hundreds of patents related to dual standby are not even available to Qualcomm.

Xiaomi in its earlier response disclosed that it holds several patent agreements with Microsoft, Nokia, and other patent holders. In addition to that, the company hinted that it is also increasing its Research & Development effort with investments in that regard. Xiaomi recently opened a new R&D center in Shenzhen, Mainland China. But if Coolpad claims to have the patent in China covering dual standby, then Xiaomi must have dabbled into its dragnet even if the patent it used was from Nokia or Microsoft since Coolpad is a Chinese holder of the same patent.

Panasonic Lumix UK division found new way for money waste! Tue, 16 Jan 2018 15:51:15 -0700 Vitaliy_Kiselev 18794@/talks/discussions

Join Lumix ambassadors at some of Britain’s most spectacular locations to highlight the advanced capabilities of the G9 and the GH5

Panasonic Lumix is proud to announce a brand new 12 month partnership with the National Trust.

Newly appointed National Trust Lumix ambassadors will go behind the scenes at special places looked after by the conservation charity to capture unique images and videos.

The six ambassadors, who work for the National Trust and have a particular flair for either photography or video, have been chosen as part of this special new partnership. Each will be using either a Lumix GH5 or G9 and sharing their stunning results - along with their top photography hints and tips - across Lumix UK’s and National Trust’s social media channels.

Rob Coleman works as the Education Officer for the Trust at Sheringham Park in Norfolk which encompasses coast, woods and parkland. Much of Rob’s work is about engaging people with the fantastic wildlife that is found at Sheringham. He says, “I really enjoy photographing insects - macro photography which enables you to see tiny creatures in close up , gives you a completely different perspective on the natural world and everyday animals like spiders and woodlice can look amazing in close-up!”

National Trust Ranger Chris Johnson works at Allen Banks and Staward Gorge in Northumberland, and finds that his Lumix is the perfect tool for highlighting the important conservation work undertaken at the site. “The most important thing for me about camera is size. I need to carry all my kit for work so it’s important not to add more weight than necessary. I also don’t have the luxury of being able to dedicate lots of time to filming so I need to be able to pick it up and get shooting.”

Harriet Davies works as a Ranger on the Roseland in South Cornwall and describes her favourite things to photograph as “wildlife and the changing coastal landscapes where I work.” You can look out for other ambassadors across the country, including Sherringham Park in Norfolk, Croome in Worcester, Allen Banks and Staward George in Northumberland, Trelissick and Rosalind in Cornwall and Saddlescombe Farm and Devils Dyke in West Sussex.

The public will also be able to get involved, borrowing cameras, lenses and accessories as part of the National Trust Roadshow which will tour a number of properties this spring. During the roadshow visitors can enjoy all the benefits of using a Lumix G system, as well as take part in photo walks and special events.

Barney Sykes, Head of Imaging at Panasonic UK said “Partnering with the National Trust is the perfect way to demonstrate the superb nature and wildlife capabilities of our latest models, particularly the super high-speed G9 which can capture full-resolution images at 20 frames per second, and the GH5 which can record 4K video at 60fps. We’re delighted to have been able to partner with the National Trust once again, and continue our roadshows which have been hugely popular over the last few years”.

Daniel Dodd, National Trust Content and Partnerships Director, said: “We hope the ambassadors can give the public a fascinating insight into an often unseen world. From tiny creatures that scurry away when people go near, to meticulous conservation work which carefully takes place behind closed doors, this project will shed light on what happens at National Trust places.”

Further details about the partnership will be revealed over the next year.

Insta360 Eight-Lens VR Camera and also 6DOF Light Field Camera Tue, 09 Jan 2018 07:34:29 -0700 Vitaliy_Kiselev 18682@/talks/discussions image

Insta360 today gave CES visitors a first look at its next wave of groundbreaking cameras, unveiling two new technologies that will let VR filmmakers immerse their audiences in experiences both more true-to-life and more interactive than ever before.

One of the new devices, an eight-lens professional VR camera, will occupy an all-new category for the leading 360° camera maker.

Capable of shooting fully spherical, stereoscopic (3D) video at upwards of 10 K resolution, this camera will be priced at roughly $12,000 USD and serve the needs of exacting VR creators at the top of their field. 4/3” image sensors will give the camera a high dynamic range and produce brilliant, noise-free shots even in low-light environments.

Specific specs, pricing and release date info will be announced at a later date.

Prototype Unveiled for 6DOF Light Field Camera

Insta360 also unveiled a new prototype for a light field camera. Leveraging 128 cameras laid out in a rectangular grid array, the camera can be used to create 180° video with 6 degrees of freedom (6DOF), meaning viewers can “move” throughout a piece of content along six directions (up, down, left, right, backward, forward).

Effectively, this means a viewer can freely change their perspective to view the same scene from any angle they choose, exactly as we do in real life. For example, a viewer might start by looking at a person’s face from a straight-on perspective. Then, by simply tilting their neck, they would shift to a three-quarter view of the face in front of them, with the curve of the nose and cheeks taking fuller shape in real time.

The 128-camera array achieves this effect by capturing a detailed representation of both the intensity and direction of light at every point within a scene. Insta360’s prototype allows freedom of movement within a range of roughly 1.5 feet (0.5 meters) in all six directions.

While the current prototype is used to record 180-degree video, the technology that Insta360 has developed can be applied to 360° capture as well. Ultimately, this technology will allow creators to record extraordinarily realistic scenes that viewers can explore at will, achieving all-new levels of immersion.

Info on specific products incorporating Insta360’s light field technology will be shared at a later date.
