David Etchell, der Gründer und Chef von imgaging resource, hat ein sehr interessantes Interview über die neusten Sensorentwicklungen von Nikon, Canon und Tamron gemacht:

http://www.imaging-resource.com/news/2016/12/11/patent-roundup-a-conversation-with-dave-etchells-about-recent-sensor-innova

 

Es werden der double layer contrast based Sensor von Nikon, der gebogene Sensor von Canon und der hochempfindliche Sensor von Tamron besprochen.

 

Hier der Tamron Teil:

3. Tamron announcement: "Low gain-noise, wide dynamic-range CMOS image sensor"

 

AA: Most recently, Tamron issued a press release that it had developed a technology that allowed for images to be created "far exceeding that of human vision, with critical consistency established between ultra-high sensitivity and wide dynamic range." The announcement is a bit vague on details, but it does offer that the sensor is receptive to "a range of brightness in excess of 140 dB (a lightness-and-darkness difference of 10 million times)".

 

DE: That 140 dB number was so astonishing that I thought it'd be interesting to take a look at just what the numbers mean, and see if I could relate them to the realities of current sensors. This is probably only for the uber-geeks, and I probably dropped a digit here or there (hoping the readers will correct me!), but here's what I came up with:

If I've got the right number of zeroes there, 140db is around 23 1/4 stops, a ratio of 10,000,000:1. The problem is, Tamron doesn't state what the two ends of the range are. The comparison images above are a bit unfair to the human eye, as a light level of 0.4 lux is about -2.6 EV, which Wikipedia tells us is on the order of the light from a full moon. (Perhaps they were assuming that the human seeing the image shown above left had just walked from bright sunlight into moonlight-levels?)

So what ISO level would the shot above correspond to? We can make an estimate of minimum shutter speed by noting that image has a person walking in it, and they're captured without motion blur, at least at the very low resolution of the sample image.

EV 0 corresponds to an exposure of 1 second with a f/1.0 lens at ISO 100. So EV -3 (rounding up slightly) would need an exposure of 8 seconds at f/1.0, or 16 seconds at f/2.0. So let's assume an f/2.0 lens, and give them the benefit of the doubt and say that they could get away with a 1/8 second exposure to capture moving person at the resolution shown. So what ISO would that be? Well, we'd go from 16 seconds at ISO 100 to 1/8 second at ISO "X". That's a factor of 128 or 7 stops, saying we'd need ISO 12,800. They don't tell us how big a sensor they're talking about, but that's well within the range of current technology.

So at the low end of the brightness range, it seems we're at least within reach of conventional sensor technology; with that set, where does it put the high end?

Well, 23 stops up from EV -3 would be EV 21, which is about five stops brighter than direct sunlight on snow. Huh? That doesn't seem it could be right (there's zero need for it), but then we have to consider what they might mean by "Dynamic Range". Technically, the "noise floor" of a system counts as the lower end of its dynamic range. So the low end of a sensor's dynamic range could be viewed as the darkest level at which the background noise is as "bright" as the image. Compared to the image shown above, that's probably a good 4 stops darker, probably more.

So it seems that they're saying that they have a sensor that can capture clear color video under full-moon light levels and go all the way to full, bright sunlight, with the same exposure settings. That is indeed something new, in that any existing camera sensors would either completely saturate at the bright end or be completely black at the dark end.

DxO measures the dynamic range of image sensors, and the highest-rated camera they've tested so far is the Nikon D810, with a dynamic range of 14.8 EV. So the Tamron sensor is or almost 350x better!

 

AA: Can we expect to see this technology rolling into consumer level cameras? Tamron has a big foothold in the security camera market, which seems to be where this technology makes the most sense.

 

DE: It's certainly very interesting. At a system level, this basically corresponds to having a 24-bit A/D converter measuring the sensor signals, vs the 10-16 bit ones we have today. You'd just set things up so the sensor would give a good exposure (that is, you'd fill the pixels) under daylight conditions, and just digitize it so finely that you could "see" all the way into -6 EV shadows.

The catch is that you probably couldn't read the data off a chip like that very quickly, meaning that you'd be restricted to pretty low resolutions. It's also aimed at a very different use-case (security cameras) than we're interested in as photographers. We don't need to go from full sun to moonlight without changing our exposure settings; we just change the shutter speed, stop down, etc. What could be interesting though, is the extent to which higher-resolution A/D conversion could significantly increase dynamic range in photographic applications. It'd certainly be nice to just expose for the highlights, but be able to pull perfectly clean detail out of even very dark shadows. The question is, though, would we be happy with either a resolution of 1 megapixel or a "burst" rate of one shot per second? Or a 12 megapixel sensor that burned 5x the power? I think those areas are where the tradeoffs are, but I also think that we're going to see cameras with higher dynamic range in the future than we have now.

Ultimately, it will come down to what the market wants: Currently, the market pressure is all in the direction of high speed: Faster, longer bursts, faster, more sophisticated AF, etc. I expect we're going to see a lot more development in that direction before dynamic range becomes a big enough differentiator for manufacturers to move in that direction.

 

AA: Thanks for your thoughts, Dave!

Vielen Dank für das Zitat! Interessant finde ich da den letzten Absatz: "Currently, the market pressure is all in the direction of high speed: Faster, longer bursts, faster, more sophisticated AF, etc. I expect we're going to see a lot more development in that direction before dynamic range becomes a big enough differentiator for manufacturers to move in that direction." Ist das wirklich so? Zeigen Kameras wie die Fuji XT-2 oder die Olympus OM-D EM1 II die Richtung, in die der gesamte Kameramarkt geht? Ich glaube, eigentlich nicht. Ich denke eher, mit diesen Kameras wird eine Lücke gefüllt, die noch zwischen DSLM und DSLR besteht. Ansonsten geht die Entwicklung doch eher in Richtung noch höhere Auflösung und noch höhere ISO.

 

Der DR hat direkt noch nie so eine große Rolle gespielt, da er sich nur schlecht vermarkten lässt. Ich glaube auch nicht, dass sich das ändern wird. Hier müssen die Hersteller im Hinblick auf das Gesamtpaket  "Bildqualität" Fortschritte von den Sensorherstellern einfordern, ohne das direkt vermarkten zu können. Sicher ist dabei aber, dass auch die besten Sensoren heutzutage im Hinblick auf die Geschwindigkeit  und den AF punkten müssen. Es müssen ja nicht gleich solche Speed-Monter wie die E-M1 II sein, aber Bildwiederholraten von unter 5ps bei vollen Autofokus sind sicher niemand mehr zu vermitteln (außerhalb der Mittelformatwelt).

Hmm, wenn mir LR dann genau den Dynamikbereich rausholt, den ich brauche, und das dann "natürlich" wiedergegeben werden kann, dann ist das doch perfekt! HDR das nicht nach HDR aussieht...

HDR ist HDR, wie das zustande kommt ist unerheblich.

Wie das Ergebnis aussieht hängt nach wie vor von den Lichtbedingungen und der Bildbearbeitung ab. 

Wenn man mal bei der Belichtung daneben haut, und das Bild  aber doch noch retten kann, ist das aber sicherlich ein Vorteil (ich denke da an Situationen wo es schnell gehen muß). Für einen Landschaftsfotografen, der sich überlegt, wann er was wie fotografiert, gibt's mittlerweile ohnehin schon zahlreiche Möglichkeiten um den eh schon sher großen Bereich noch zusätzlich zu erweitern (Mehrfachbelichtunge,in-Kamera HDR, Sensorshift). Mich wundert eigentlich nur, wie wenig die bestehenden Möglichkeiten tatsächlich genutzt werden, und wie viel über fehlende Dynamik seit Jahren gejammert wird. Aber vielleicht täuscht der Eindruck.

...Die KBler sagen, wir brauchen kein MF, KB-Sensoren sind gut genug, APCler und MFTler sagen ähnliches von ihren Sensoren.

 

Ich stimme Dir nicht zu! Ich will für MFT einen erheblich besseren Sensor, damit ich Leuchten exakt ohne Halo abbilden ...

Hmm, ich habe gerade als MFler mit Halos um Spitzlichter zu kämpfen, die ich mit MFT nicht so ausgeprägt habe. Das hat nur wenig mit dem Sensor selbst zu tun (das können chrom. Aberrationen und/oder Reflexionen zwischen Hinterlinsen/Sensor-Deckglas/Sensor sein) . Wenn Du so spezielle Anforderungen hast, dann hilft nur unterschiedliche Kamera-Objektivkombinationen unter genau diesen Bedingungen auszuprobieren.

.... doch eher in Richtung noch höhere Auflösung und noch höhere ISO.

....

Da muß man wohl darauf hinweisen, daß "höhere ISO" eher einer Rückentwicklung gleich käme.

Das Verstellen der "ISO" ist und war noch nie etwas anderes als eine Verstellung der Signal-Verstärkung (passendere Bezeichnung : "gain"). Und diese Verstärkung hilft nur dann, wenn sich dadurch das beim Auslesen des Sensorsignals auftretende Ausleserauschen verringert. Ein guter Sensor hat aber von Haus aus ein niedriges Ausleserauschen - die Verstärkung bringt zwar (momentan) auch noch was, aber nur mehr wenig. Ein wirklich guter Sensor könnte künftig überhaupt ohne ISO-Verstellung (aber dafür mit höherer A/D-Auflösung) auskommen.

LaserFocusWorld: Nabeel A. Riza, University College Cork, Ireland, and colleagues say to have demonstrated the Coded Access Optical Sensor (CAOS) CMOS camera, or CAOS-CMOS, with a three-orders-of-magnitude improvement in camera DR when compared to a conventional CMOS camera.

"Light from an external object is directed by a lens (L1) onto the agile pixels plane of a programmable digital micromirror device (DMD). To initiate the imaging operation, the DMD micromirrors are set to spatially route the incident light to the CMOS sensor to create an initial target-scene irradiance map. Based on this initial image intelligence, the DMD is programmed in its CAOS mode to create specifically located agile pixels that sample image zones of interest.

This agile-pixel programming capability via the DMD allows the agile pixels to operate with different time-frequency coding methods such as frequency/code/time division multiple access (FDMA/CDMA/TDMA) schemes common in cell-phone radio-frequency (RF) communications.

Experiments demonstrate a CAOS-CMOS camera dynamic range of 82.06 dB, which can be improved upon by further optimization of the camera hardware and image processing.
“The CAOS camera platform, when used in unison with current multipixel sensor camera technology, is envisioned to enable users to make a smart extreme-dynamic-range camera, opening up a world of the yet unseen,” says Nabeel Riza."

By Leah Burrows

Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image.  That’s why high-power microscopes are so big and telephoto lenses so long.

While lens technology has come a long way, it is still difficult to make a compact and thin lens (rub a finger over the back of a cellphone and you’ll get a sense of how difficult). But what if you could replace those stacks with a single flat — or planar — lens?

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light — covering the whole range of colors from red to blue. The lens can resolve nanoscale features separated by distances smaller than the wavelength of light. It uses an ultrathin array of tiny waveguides, known as a metasurface, which bends light as it passes through.

The research is described in the journal Science.

“This technology is potentially revolutionary because it works in the visible spectrum, which means it has the capacity to replace lenses in all kinds of devices, from microscopes to cameras, to displays and cell phones,” said Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering and senior author of the paper. “In the near future, metalenses will be manufactured on a large scale at a small fraction of the cost of conventional lenses, using the foundries that mass produce microprocessors and memory chips.”

"Correcting for chromatic spread over the visible spectrum in an efficient way, with a single flat optical element, was until now out of reach," said Bernard Kress, Partner Optical Architect at Microsoft, who was not part of the research. "The Capasso group's metalens developments enable the integration of broadband imaging systems in a very compact form, allowing for next generations of optical sub-systems addressing effectively stringent weight, size, power and cost issues, such as the ones required for high performance AR/VR wearable displays."

In order to focus red, blue and green light — light in the visible spectrum — the team needed a material that wouldn’t absorb or scatter light, said Rob Devlin, a graduate student in the Capasso lab and co-author of the paper.

“We needed a material that would strongly confine light with a high refractive index,” he said. “And in order for this technology to be scalable, we needed a material already used in industry.”

The team used titanium dioxide, a ubiquitous material found in everything from paint to sunscreen, to create the nanoscale array of smooth and high-aspect ratio nanostructures that form the heart of the metalens. 

“We wanted to design a single planar lens with a high numerical aperture, meaning it can focus light into a spot smaller than the wavelength,” said Mohammadreza Khorasaninejad, a postdoctoral fellow in the Capasso lab and first author of the paper.  “The more tightly you can focus light, the smaller your focal spot can be, which potentially enhances the resolution of the image.”

The team designed the array to resolve a structure smaller than a wavelength of light, around 400 nanometers across.  At these scales, the metalens could provide better focus than a state-of-the art commercial lens.

“Normal lenses have to be precisely polished by hand,” said Wei Ting Chen, coauthor and a postdoctoral fellow in the Capasso Lab. “Any kind of deviation in the curvature, any error during assembling makes the performance of the lens go way down. Our lens can be produced in a single step — one layer of lithography and you have a high performance lens, with everything where you need it to be.”

"The amazing field of metamaterials brought up lots of new ideas but few real-life applications have come so far," said Vladimir M. Shalaev, professor of electrical and computer engineering at Purdue University, who was not involved in the research. "The Capasso group with their technology-driven approach is making a difference in that regard. This new breakthrough solves one of the most basic and important challenges, making a visible-range meta-lens that satisfies the demands for high numerical aperture and high efficiency simultaneously, which is normally hard to achieve."

One of the most exciting potential applications, said Khorasaninejad, is in wearable optics such as virtual reality and augmented reality. 

“Any good imaging system right now is heavy because the thick lenses have to be stacked on top of each other. No one wants to wear a heavy helmet for a couple of hours,” he said. “This technique reduces weight and volume and shrinks lenses thinner than a sheet of paper.  Imagine the possibilities for wearable optics, flexible contact lenses or telescopes in space.”

AbstractA quanta image sensor (QIS) is a class of single-photon imaging devices that measure light intensity using oversampled binary observations. Because of the stochastic nature of the photon arrivals, data acquired by QIS is a massive stream of random binary bits. The goal of image reconstruction is to recover the underlying image from these bits. In this paper, we present a non-iterative image reconstruction algorithm for QIS. Unlike existing reconstruction methods that formulate the problem from an optimization perspective, the new algorithm directly recovers the images through a pair of nonlinear transformations and an off-the-shelf image denoising algorithm. By skipping the usual optimization procedure, we achieve orders of magnitude improvement in speed and even better image reconstruction quality. We validate the new algorithm on synthetic datasets, as well as real videos collected by one-bit single-photon avalanche diode (SPAD) cameras. View Full-Text

So was ähnliches habe ich kürzlich auch irgendwo gesehen. Da wurden aber die Spektralfarben in unterschiedliche Winkel geteilt.

Sah auch interessant aus. Bin nur gespannt was sich schlußendlich von diesen ganzen Entwicklungen durchsetzen wird.

Hier noch ein kurzer Artikel von depreview über das Thema inkl. global shutter:

https://www.dpreview.com/news/8520769466/new-cmos-image-sensor-tech-enables-high-resolution-long-duration-slow-mo-recording

 

Sensor innovations push global shutter chip capabilities

Published Dec 21, 2016 | Brittany Hillen

 

   

Engineers with Tohoku University have detailed a new project in which a CMOS sensor with a global shutter is able to record ultra-high-speed footage without the constraints of existing technology, namely short-duration recording and low resolutions. The end result is a CMOS sensor capable of recording one million frames-per-second over a 'large' duration of time, relatively speaking (480 micro-seconds in this case), at full resolution.

By re-designing the sensor's memory bank, researchers have tested a 96 x 128 pixel array with global shutter at 480 frames. The design is intended to be tiled on a sensor with 1MP resolution – clearly not enough for consumer photography, but great for engineering applications. 

Don't feel left out though, consumer photography and videography may also see benefits from this kind of technology – Canon also reported progress on its research of global shutter sensors. Canon's technology similarly uses memory in an innovative way: by assigning each pixel its own memory cell. While Tohoku University's research is concerned with ultra high speeds, Canon is looking for ways to improve the dynamic range of global shutter sensors. The company has tested a 10MP sensor at 30 fps – take a look at the results below. 

Global shutter chips typically offer poor dynamic range. To improve DR, Canon has increased the number of 'accumulations' per frame, or the number of times each pixel deposits electrons to its associated memory cell. Image supplied by Canon

Pentax schafft zwar tatsächlich eine ziemlich hohe Qualität bei moderaten Preisen, aber solche HighISO-Bereiche tatsächlich mit guter BQ zu erledigen wird noch eine längere Zeit dauern.

Die offiziell (am 26.01.2017 erst) kommende Pentax-KP ist eine Brücke zwischen klassischer DSLR und Retrodesign-Body (gibbet ja in Solber) und kommt mit dem "neueren" der Sony 24mP Sensoren daher, aber wundersame Supersensorqualität wird auch diese nicht liefern. Diese Baureihe steht für andere Innovationen wie z.B. sich im Lieferumfang befindliche seitliche Griffstücke, die selbst angeschraubt werden können, und einem neuen Bedienkonzept (wie das wirklich gut durchdachte Konzept der K-1) - den Sensor sehe ich da nicht als eine große Innovation an. Vermutlich ist das der Sony-Sensor, der zu hauf auch in anderen Modellen der verschiedenen Hersteller verbaut wurde.

 

[Gast User73706]

Den ISO-Wert hatte ich zuvor noch nicht bei einer APS-C gelesen. Mal schauen, ob es nur eine werbeträchtige Zahl ist oder ob mehr hinter dem "neuen" Sensor steckt...
