This newly developed sensor with DRAM delivers fast data readout speeds, making it possible to capture still images of fast-moving subjects with minimal focal plane distortion as well as super slow motion movies at up to 1,000 frames per second (approximately 8x faster than conventional products in full HD (1920x1080 pixels).


The high-speed readout capability makes it possible to record up to 1,000 fps (approximately 8x faster than conventional products*3) super slow motion movies in full HD (1920x1080 pixels). Normal speed shooting data and maximum 1,000 fps high-speed shooting data stored on the DRAM are exported from the image sensor for signal processing on an external image signal processor (hereafter referred to as ISP), making it possible to record vibrant movies on a smartphone that seamlessly combine normal speed movies and super slow motion movies. To ensure that users don't miss split-second moments in super slow motion movies, it is possible to adjust settings so that sudden subject movement is automatically detected and high-speed shooting begins. Because high-speed shooting data is stored on the DRAM and output at a normal speed, a conventional ISP can be used

4K and UltraHD Stuff, Cinemas, Camcorders, TVs Sat, 30 Jun 2012 20:40:35 -0600 Roberto 3741@/talks/discussions When a local cinema replaced their film projectors with only 2K instead of 4K, I was disappointed. Sony explains why.

Picture Height: the measure of viewing distance


When the standard definition television system was first launched in North America, engineers assumed that viewers would want to sit at a sufficient distance for the individual scanning lines that comprise the picture to blend into a visually seamless whole. In the days before pixels, these engineers figured on 60 horizontal scanning lines per degree. From this, they derived a standard viewing distance of 7.15 Picture Heights (PH). Studies by Bernard Lechner of RCA in the US and Richard Jackson at Philips Laboratories in Europe determined that actual viewing distance for standard definition TV is around 10 feet (3 meters).8 The screen size that corresponds to 7.15 Picture Heights at this distance is 28 inches diagonal. This roughly matches the larger CRT sizes of the standard definition era.

Movie theater design has been influenced by similar calculations. In the 1940s, the Society of Motion-Picture Engineers (SMPE) made a recommendation called the 2-6 rule.9 It proposed that theater auditoriums be designed with the nearest seats at two times picture width and the farthest at six times picture width. Using the Academy Aperture screen shape of the time, that translates to a minimum viewing distance of 2.67 Picture Heights.

When high definition television was first proposed, the design goal was to equal the performance of movie theaters. This dictated an increase in TV resolution sufficient to create the illusion of a seamless image at roughly three Picture Heights.10 (The actual figure is 3.16 Picture Heights.) This similarity to the 2.67 specification of old movie theaters is not a coincidence. It is by design.

Since the 1940s, just about everything in movie theaters has been transformed, including auditorium design. Through the 1990s, new theater designs moved to progressively wider-angle projection lenses, which suggests that seats became progressively closer to the screen.11 By 1994, viewing distances that had once been considered the minimum were now close to the maximum. The renamed Society of Motion Picture and Television Engineers (SMPTE) issued Engineering Guideline EG 18- 1994, which recommended that the screen subtend a minimum horizontal angle of 30 degrees for viewers in the back of the room. This corresponds to a distance of 3.45 Picture Heights (using the5 contemporary picture proportions of 1.85:1). EG 18-1994 proved to be a snapshot of best practices at the end of the era of sloped-floor auditoriums.

It was withdrawn in 2003 as inappropriate for the new era of stadium seating auditoriums, which bring the audience even closer. In stadium seating, the back of the house is about three Picture Heights from the screen while the closest seats are less than one Picture Height away.

On RED Helium 8K DxOMark Sensor Score Thu, 12 Jan 2017 06:07:51 -0700 Vitaliy_Kiselev 16322@/talks/discussions image

Given the Helium 8K’s very impressive noise scores, we wanted to see if it is applying noise reduction before outputting the “RAW” files. The first kind we tested for is the most typical, spatial noise reduction. This is usually a sophisticated form of smoothing areas that appear to have noise, while retaining edges to minimize the loss of sharpness. This approach typically results in a spreading out of the frequency response of the image, and therefore can be detected through careful analysis.
Just as when we tested the RED Dragon for spatial noise reduction, we didn’t see any evidence of this type of smoothing, as there is no correlation between neighbor pixels.

The high frame rate possible with RED’s sensors, including the Helium, mean that they are especially well-suited for noise reduction based on sampling multiple sequential image frames. This technique, called temporal noise reduction (TNR), is most commonly used in video, since there are many successive frames to work with . However, temporal correlations across a time axis are not relevant when analyzing the image quality of a single RAW image, as they do not impact any RAW converters.

Whatever noise reduction system RED employs creating the RAW images from the Helium sensor, its presence means that we aren’t measuring just the RED sensor, so its results aren’t directly comparable to those from camera sensors we have tested from other vendors, whose RAW results come straight from the sensor with no prior noise reduction processing.

Some people do not like to read things before blaming someone :-)

Of course DXOMark carefully avoided mention of known fact that some companies also do noise processing of raw files.

The true reasons for a full frame camera Mon, 02 Jul 2012 22:36:10 -0600 Vitaliy_Kiselev 3760@/talks/discussions There is an amazing amount of false information floating around the internet when it comes to the benefits of form factors such as 35 mm full frame or APS-C. Typical examples include statements that full frame equals more shallow depth of field, less noise or unreasonably high sensor cost. Or that APS-C is better because it is good enough in a smaller and less expensive package. Unfortunately, such statements are too simple to be possibly true.

Full frame basically offers more choice or options which may or may not lead to better image quality or other benefits. It is necessary to look at each aspect in somewhat more detail. Therefore, I compiled a LumoLabs white paper listing the true reasons in favour of a full frame or APS-C camera:

Google claims to have invented the "limitless CSI-style zoom" Tue, 07 Feb 2017 16:05:26 -0700 karl 16430@/talks/discussions You have probably seen at least one of those videos where some high-tech crime unit obtains a blurry, tiny image of some bad guy from a surveillance camera, and then effortlessly "zoom in" until they got a perfect portrait image out of a few pixels.

Well, seems that Google just claimed to have invented such technology.


But don't let the images fool you: "Deep neural networks" have already been shown to be easily fooled when classifying pictures, and I dont's see why a tool like the great Ostrichinator could not just as easily fool Google's "guessing zoom" to derive the picture of some arbitrary person from just any seemingly innocent 8x8 pixel sample.

GoPro sales fall Wed, 13 Jan 2016 16:00:28 -0700 Vitaliy_Kiselev 14428@/talks/discussions

GoPro has laid off 7 percent of its workforce, and warned investors of poor sales of the company's action cameras. The news comes just a few weeks before GoPro is set to officially announce its fourth quarter earnings for 2015.

The company is also downgrading its guidance for the fourth quarter from about $500-$550 million in revenue to $435 million. GoPro blames that drop on what it's calling "lower than anticipated sales of its capture devices" in the final quarter of 2015. That would represent about a 70 percent drop in sales from the company's big fourth quarter in 2014, when it brought in $633.9 million in revenue. Industry analysts were originally projecting that GoPro's Q4 revenue in 2015 would be somewhere closer to $690 million.

ON Semi Sensors Power ARRI Cameras Fri, 03 Feb 2017 08:57:15 -0700 endotoxic 16402@/talks/discussions ON Semi says that for the past five years, every movie to win Oscar Award – Hugo (2011), Life of Pi (2012), Gravity (2013), Birdman (2014) and The Revenant (2015) – was captured using an ALEXA or ALEXA 65 digital camera system from ARRI. For 2016, four of the five nominees for Best Cinematography were again captured using ALEXA cameras. These cameras high DR, natural color reproduction, and high sensitivity, all begin with the performance of ON Semi image sensors used in the system.

ARRI publishes an explanation of image sensor technology used in its cameras:

"Although the science behind the breakthrough performance of ALEXA's custom designed CMOS sensor is complex, the use of large photosites and a Dual Gain Architecture are its two main principles.

By employing unusually large photosites (in today's world of tiny cell phone sensors), ALEXA's sensor exhibits high dynamic range, high sensitivity and low crosstalk. The larger a photosite is, the more light it can capture and the lower the noise.

The Dual Gain Architecture simultaneously provides two separate read-out paths from each pixel with different amplification. The first path contains the regular, highly amplified signal. The second path contains a signal with lower amplification, to capture the information that is clipped in the first path. Both paths feed into the camera's A/D converters, delivering a 14 bit image for each path. These images are then combined into a single 16 bit high dynamic range image."

3D: LG and Sony stopping 3D TV production Sat, 21 Jan 2017 15:37:21 -0700 Vitaliy_Kiselev 16357@/talks/discussions

LG and Sony, the last two major TV makers to support the 3D feature in their TVs, will stop doing so in 2017. None of their sets, not even high-end models such as their new OLED TVs, will be able to show 3D movies and TV shows

Sharp, TCL and Hisense, also did not announce any 3D-capable TVs at CES 2017.

I have only one word for them. Motherfuckers.

Note that passive 3D fall is closely related to HDR, as polarization film take off brightness and also add costs. At same time quantum dots and HDR are very cheap to make.

For all active 3D television with removal of 3D Samsung changed panels to cheaper and slower ones, adding good profit.

Remember to buy 4K OLED with passive 3D, looks amazing.

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.

Ambarella H22 4K Ultra HD SoC Announced Fri, 06 Jan 2017 03:30:11 -0700 Vitaliy_Kiselev 16290@/talks/discussions

SANTA CLARA, Calif., January 5, 2017 -- Ambarella, Inc. (NASDAQ: AMBA), a leading developer of low-power, HD and Ultra HD video processing semiconductors, today introduced the H22 System-on-Chip (SoC) targeting a new generation of 4K drones and sports cameras with leading-edge video features.


The new H22 SoC is capable of encoding 4K Ultra HD video at 60 frames per second using the H.265 (HEVC) or H.264 (AVC) video formats, and supports advanced Electronic Image Stabilization (EIS) up to 4K resolution. The on-board 1.2 GHz Quad-Core ARM® Cortex®-A53 CPU provides significant processing power for customer applications including flying camera flight control, advanced analytics, video stitching and wireless networking. Fabricated in 14nm process technology, the H22 offers very low power consumption, enabling 4K cameras with small form factors and extended battery life.

“The H22 brings 4Kp60 Ultra HD video at extremely low power into the mainstream,” said Chris Day, VP of marketing and business development at Ambarella. “With 4K HDR, 4K EIS, and a quad-core CPU, the H22 enables a new generation of drones and sports cameras with outstanding video quality and extended battery life.”

The H22 includes a highly optimized image processing pipeline with excellent imaging and advanced noise reduction, and a hardware de-warp engine to support wide-angle panoramic designs with minimal distortion. The device’s 4K EIS can augment or potentially eliminate the need for a mechanical gimbal in a drone. The ability to encode at high frame rates, including 4Kp60 and 1080p120, delivers smooth slow motion, high definition video even during fast action shots.

A typical use case for the H22 in a drone might be to simultaneously encode 4K Ultra HD video, stabilize it in real time using EIS, and execute flight control algorithms using input from an array of sensors including an optical flow sensor. Additionally, a second, low-delay, Full-HD live video stream may be processed, encoded and wirelessly transmitted to the pilot for monitoring and camera control

Ambarella H3 8K Ultra HD SOC announced Fri, 06 Jan 2017 03:28:25 -0700 Vitaliy_Kiselev 16289@/talks/discussions

Ambarella, Inc. (NASDAQ: AMBA), a leading developer of low-power, HD and Ultra HD video processing semiconductors, today introduced the H3 System-on-Chip (SoC) for high-end drones and a new generation of video cameras, including 360-degree and virtual reality cameras. The H3 video SoC enables 8K Ultra HD H.264/AVC video at 30 frames per second, as well as multiple video streams with equivalent performance, including 360-degree cameras with dual 4KP60 sensor video capture.


8K videos played on large 8K displays provide a better viewing experience to the end user, as pixels at this resolution are indistinguishable to the human eye at any reasonable distance. The combination of 8K video capture together with Ambarella’s advanced oversampling and image stabilization also enables higher video quality 4K video recording.

“With the introduction of H3 we believe we provide the highest video performance and best image quality solution for high-end drones and multi-sensor video cameras,” said Fermi Wang, president and CEO of Ambarella. “H3 delivers 8Kp30 video performance to match the next generation of displays, such as 8K televisions and high resolution head-mounted displays.”
