Canon "Dual Sensing IS"

Nikkei reports few interesting details about image stabilization implementation in the recently announced Canon G7X Mark II compact camera leveraging the high speed of its image sensor:

"While the previous product stabilizes images with a gyroscope, the new product takes into account the data on the amount of camera shake obtained from the image data collected by the CMOS sensor. Canon calls this function "Dual Sensing IS."

In addition, a "panning" mode was added by using the image stabilization function. The camera instantly analyzes the moving speed of the camera and the moving speed and direction of the subject and calculates the best shooting conditions. As a result, it became easy to take an image with a flowing background while stabilizing the image of the subject.

Oppo Presents 3-axis SmartSensor Image Stabilization for Smartphones

Oppo presents its new smartphone featuring SmartSensor sensor-based image stabilization for smartphones. While OIS in most smartphones is based on lens shift, Oppo SmartSensor shifts image sensor, as shown in this Youtube video:

The advantages over the lens-based OIS are:
  • Not only camera yaw and pitch, but also roll is compensated
  • Very fast sensor movements, under 15ms time required for image stabilization, said to be 3 times faster than lens-based OIS
  • Power consumption as low as 10mW, said to be 50 times lower than lens-based OIS
  • High accuracy of of compensation of 0.3um, while lens-based systems are said to be 10 times less accurate

"So why is the SmartSensor just now arriving? Let's have a look at just how difficult it was to bring about this technology.

To achieve three-axis sensor-based stabilization, the image sensor needs to be suspended in a very small space to allow for rotation around a central axis.

Another challenge brought by suspension is signal transmission. The SmartSensor presents the challenge of having to connect over 200 signal wires from the floating sensor to the main board.

This was the key puzzle that OPPO and MEMS Drive solved through years of research.

GSM Arena reports from the MWC 2016 Oppo booth: "Oppo SmartSensor image stabilization can correct up to 1.5° of motion and works on sensors ranging from 1/1.8" (bigger than any phone yet) and 1/3" (typical of mid-range phones). It's also smaller than a typical OIS module, so we may see it in thinner phones." While being a very impressive technology, 1.5deg is somewhat limited range for a high quality OIS.

Apparently, the company that supplied the technology to Oppo is MEMS Drive, based in Pasadena, CA.

0.25e- Pixel Noise in 2007

It was brought to my attention that in 2007, IEEE Transactions on Nuclear Science published Max Plank Institute paper "A Novel Way of Single Optical Photon Detection: Beating the 1/f Noise Limit With Ultra High Resolution DEPFET-RNDR Devices" by Stefan Wolfel, Sven Herrmann, Peter Lechner, Gerhard Lutz, Matteo Porro, Rainer Richter, Lothar Struder, and Johannes Treis. The paper is also available for free download here. The described pixel structure allows a multiple reading and averaging of the photoelectric signal, so that 1/f noise can be averaged:

"In this work we demonstrate theoretically and experimentally the capability to reduce the readout noise of an optical and X-ray photon detector based on the semiconductor DEPFET device below a level of only 0.3e- ENC (equivalent noise charge). The readout method used is called "repetitive non destructive readout" (RNDR) and was realized by placing two single DEPFET-devices next to each other and by coupling their charge storing region by an additional gate. By transferring the stored charge from one DEPFET to the other and vice versa the same charge can be measured non-destructively and arbitrarily often. Taking the average value of a large number n of these measurements, the noise is reduced by 1/radicn. The main advantage of such a detector is to greatly reduce the contribution of the 1/f noise to the readout noise. The theoretically and experimentally achievable resolution for different operating parameters (leakage current, readout noise, number and duration of readouts) was investigated by Monte-Carlo simulations and verified on a real RNDR minimatrix (pixelarray). Single optical photon detection with high quantum efficiency and, even more fascinating, the possibility to distinguish between different numbers of photons, e.g., 100 from 101 are demonstrated in measurements."

More About Invisage SparkP2 Sensor

ExtremeTech seems to get some exclusive marketing materials on the Invisage SparkP2 sensor:

"Due to the composition of our atmosphere, the sun emits only about a quarter of the radiation at 940nm than it does at 850nm. That means that a much-less-powerful LED can be used for outdoor applications, and still be effective. That is why the SparkP2 out-performs current-model back-side illuminated (BSI) sensors outdoors — even using a much-lower-power 10 mW LED instead of a 750 mW LED — at least according to Invisage’s tests:"

An Easy Way to Sue Image Sensor Company

A lawsuit of HSM Portfolio LLC and Technology Properties Limited LLC against Micron shows how easy image sensor company can be accused in patent infringement. Some of Micron image sensor products allegedly infringe on some of 3 patents:

US5001367 "High speed complementary field effect transistor logic circuits" filed in 1989 and describing an inverter chain with a sequential size scaling.
US5030853 "High speed logic and memory family using ring segment buffer" filed in 1990, describing an inverter chain with a positive feedback.
US5391949 "Differential latching inverter circuit" filed in 1995, describing a latched logic buffer.

Neither patent has a direct relation to the image sensor technology.

Invisage Unveils 2MP NIR Sensor

BusinessWire: Invisage announces SparkP2 sensor featuring global shutter, 3x higher light response in 940nm NIR band and over 20x lower power consumption than competing solutions. SparkP2 is a 1.1 um pixel, 2MP QuantumFilm sensor in 1/7-inch format for a less than 3mm thin z-height.

Talking about structured light 3D sensors, InVisage QuantumFilm global shutter works in tune with a pulsed LED, which optimizes the LED battery usage to be just 10 mW (versus 750 mW for LEDs used with rolling shutter NIR cameras). SparkP2’s fast global shutter allows the NIR light source to be pulsed for extremely short intervals instead of remaining continuously illuminated, thus overcoming sunlight while at the same time capturing movement more accurately and using far less net power.

SparkP2 is sampling in April 2016 with mass production scheduled by Summer 2016.

Brian O’Rourke, Senior Principal Analyst, Consumer Devices and MEMS & Sensors at IHS Technology, said in an email to VentureBeat, “There’s certainly opportunity here for InVisage. The types of use cases that they’re going after, such as facial and iris recognition, depth-mapping and eye and gesture tracking, have a wide variety of imaging applications, from security to online banking to gaming. These will all benefit from better performance in the IR range. These applications should grow significantly over the next few years, from a limited current base. The barrier for InVisage is the strong, established companies that they will be competing against in the image sensor market, companies like Sony, Samsung, OmniVision and ON Semiconductor. As a start-up, it’s extremely difficult to compete against companies that currently generate billions of dollars in revenue in your target market. You not only have to build a better mouse trap, but you have to be able to market it effectively.

We exceeded our objectives for 2015; gearing ULIS towards even higher prospects in 2016. I am very happy with my team and their dedication. I thank them for their drive and support,” said Jean-François Delepau, managing director of ULIS. “Our customer base also grew in 2015. The price/performance of our complete portfolio of Pico Gen2 products made a significant impact; they struck the right chord with camera makers and system developers across many market applications. In 2016, we will aim even higher to bring even greater product and service satisfaction to our customers.

ULIS is said to be the second largest producer of microbolometric thermal image sensors. Since its creation in 2002, the company has delivered 500,000 thermal sensors to equipment makers. Delepau is confident that the company’s growth rate will maintain the same pace for the next two years, then accelerate due to further penetration into new markets, such as smart buildings and automotive. “As early as January 2015, we saw initial signs that we would secure a high percentage of sales. This year, we have already begun seeing other positive indicators.

Currently, ULIS is close to going to market with its Pixel Level Packaging (PLP), which is at the industrial process stage. As the pioneer of the 17um pixel pitch thermal image sensor, the current industry standard, ULIS is pursuing development of its 12um pixel pitch thermal image sensors, which is nearing completion.

EETimes: Imaging Revolution - Forget Frames

EETimes: "Two French scientists, Ryad Benosman and Christoph Posch... founded Chronocam in 2014. They’ve developed an image sensor designed to capture images not based on artificially created frames, but driven by events within view.

“Each pixel individually controls its sampling – with no clock involved – by reacting to light, or changes in the amount of incident light it receives,” explained Posch, Chronocam’s CTO.

“Frame-based video acquisition is fundamentally flawed,” Chronocam CTO Posch decreed.

Chronocam has applied and tested its sensor’s principles in restoring people’s vision at Pixium Vision, a retina prosthetic company founded by Chronocam’s co-founders.

Chronocam has raised 1.5 million euro so far. Among investors are CEA Investment and Robert Bosch VC.

Chronocam’s CCMA ATIS 1.1 sensor, whose supply voltage is 3.3V (analog), 1.8V(digital), comes in a 9.9 x 8.2mm2 chip size, featuring 2/3-inch optical format. Its array size is 304 x 240 QVGA, with a pixel size of 30μm × 30μm. The power consumption is less than 10mW.

Asked about the company’s next steps, Verre, the CEO, said, “We aim at decreasing pixel pitch and increasing resolution. Our next steps are the VGA tape out and the migration to a CIS process.”

Chronocam is open to licensing its technology to others.

Imec Introduces Broad Spectrum Hyperspectral Imager

Imec presents a new hyperspectral sensor with extended spectral range, going from the visible light (VIS) up to near infrared (NIR). The new line-scan VNIR (visible to near-infrared) sensor and snapshot mosaic VNIR camera outperform current solutions in spectral range and compactness.

Example applications for the line-scan sensor are machine vision and remote sensing applications, e .g. precision agriculture using UAVs and satellites. It features 140+bands in the 470-900nm range. Its small form factor is the result of extreme integration of the hyperspectral filter onto the CMOS sensor.

Working closely with two of our camera partners, VRmagic and Cubert Gmbh, we have realized one of the most advanced snapshot hyperspectral imaging cameras. It captures 40+ bands ranging from 450-875 m, at video-rate speed acquisition. This achievement clearly sets a new milestone for the real-time snapshot hyperspectral imaging camera market,” explains Jerome Baron, Business development manager integrated imaging at imec.
