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.

Personal View needs your help to make community lab Sun, 13 Nov 2016 23:13:55 -0700 Vitaliy_Kiselev 16041@/talks/discussions What we did last month

  • Started making independent field monitor panels measurements, 2 monitors measured, more to follow
  • Started measuring AC consumption, measurement of NP batteries powered DC consumption coming later
  • Started measuring light luminous emittance, flicker, you'll find first results in reviews soon.
  • Started measuring led lights spectrum, CRI and such, you'll find first results in reviews soon.
  • Will start measuring detailed temperature readings of led lights this month as they can cause degradation and show quality, both contact and IR way.

Why we ask you for support

  • We need your support to get some testing equipment now (want to get thermal camera and spectrometer for PV test laboratory).
    • We reached first goal - thermal camera, thanks to all members.
    • We reached second goal - light intensity meter and thermocouple
    • All is going to spectrometer now
  • We need your support to form small review fund to get non expensive items for tests, get and test them on members request and sell.
  • If you have some gear and want us to make review, you can contact me by PM.
  • Let us know the gear and specific tests you want to see, you can post in this same topic


  • PV does not have ads, "sponsors" or any such crap injecting stuff. We are here for you, not for ads.
  • We even do not have auto playing video ads what became trend in last few months. :-)
  • Each month we pay for dedicated server hosting and it this sum is not small, and additional daily backup located outside of hoster network (for safety).
  • We don't have big team to support site. No admins, paid moderators, etc. All this time is invested in keeping this community alive.
  • Remember to support regularly, even with very small amounts, if you are in economic trouble.

Where we are going:

  • We are making gear reviews and slowly improving in it - Neway unpacking came, few PV new reviews coming soon, few members reviews also
  • We are improving our deals and will add new partners and good items soon - expect new Fotga, new monitors, new Skier items this month
  • We'll also have some software updates focusing on new features and becoming more tablet and mobile friendly - work is being done in this regard, moving slowly.
  • We have new video contests coming - working on this with few manufacturers.
  • Stay tuned.

Sony Introduces 3-Layer Stacked Sensor with DRAM for Smartphones Mon, 06 Feb 2017 22:08:30 -0700 Vitaliy_Kiselev 16422@/talks/discussions

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

New Super Hi 8k format Sat, 25 Aug 2012 06:38:36 -0600 stelldust 4364@/talks/discussions ITU has just approved the new Super-Hi format. I expect we will first see TVs with the new format. Any speculations on how long it may take to see consumer products for this format?

The 8K format will host a resolution of 7,680 by 4,320 pixels, which is 16 times as sharp as current HD TVs and offers resolutions of around 2MP. This is approximately the equivalent of a 32 megapixel photo. A new high-resolution tv format that is 16x sharper than today's HDTV has been approved. A new high-resolution tv format that is 16x sharper than today's HDTV has been approved.

Japanese broadcaster NHK has developed three cameras able to film in this Super Hi-Vision resolution at 120 frames per second.

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.

From Sony - Does 4K really make a difference?

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."

Things can happen if you rely on one sensor manufacturer Fri, 22 Apr 2016 04:17:30 -0600 Vitaliy_Kiselev 14999@/talks/discussions

Due to the earthquake of April 14, 2016 and subsequent earthquakes in the Kumamoto region, Sony Corporation ("Sony") expects that it will be unable to formulate the forecast for its consolidated results for the fiscal year ending March 31, 2017 in the usual timeframe.

The survey of damage to the Kumamoto Technology Center conducted so far has revealed damage to certain parts of the building, clean rooms and production equipment. The timeframe for resuming operations has yet to be determined. The Kumamoto Technology Center is the primary manufacturing site for image sensors for digital cameras and security cameras as well as for micro-display devices.

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.
