DynaOptics announces its Kickstarter fundrasing campaign for the OOWA rotationally asymmetrical lens:

"A lens that is rotationally asymmetrical does not look the same after you turn it around it’s center point. The number of positions in which the object looks exactly the same is called the order of the symmetry. In OOWA, we are using second order symmetry.

Due to the second order symmetry in our free-form lenses, we are able to optimize image quality in a rectang ular shape, mapping this high-quality image space onto the rectangular sensor.

Invisage Unveils 13MP NIR Sensor with 1.1um Pixels

Image Sensors World        Go to the original article...

BusinessWire: InVisage launches the Spark4K NIR camera sensor. A 1.1um pixel, 13MP sensor in a 1/3-inch module, Spark4K is said to feature the world’s highest NIR resolution and 4K video at 30 fps, targeting augmented reality, autonomous, and authentication systems that require high-resolution, high dynamic range NIR imaging with global shutter capability.

Spark4K leverages the QuantumFilm technology platform’s combination of higher sensitivity with electronic global shutter to minimize power consumption while overcoming the glare of ambient infrared in sunlight. The photosensitivity of NIR-optimized QuantumFilm is sad to be 5x higher than conventional silicon at 940nm wavelength, allowing the Spark4K pixel to deliver 35% quantum efficiency. Spark4K can accurately detect a brighter but shorter LED pulse that instantaneously outshines ambient infrared light to help devices navigate and learn about their environments more accurately in pitch darkness or in direct sunlight. In addition, by pulsing the LED in sync with Spark4K’s global shutter, systems reduce battery consumption dramatically, enabling more compact, lighter weight product designs. The applications include drones, self-driving vehicles, and augmented reality devices that will benefit from Spark4K’s extended range and power savings.

After the recent launch of our 2-megapixel NIR sensor SparkP2, we’re excited to expand our IR product portfolio with a higher resolution infrared camera sensor,” said Jess Lee, InVisage President and CEO. “As machine vision enters the mass consumer market of phones, drones, cars and AR headsets, the demands are clear. Small-footprint, high-resolution infrared cameras that perform invisibly indoors and outdoors are a must. By pairing higher sensitivity with a short pulse 940-nanometer source, our Spark products easily save 50 times on power compared to a conventional camera while overpowering sun irradiance.

InVisage’s Spark line of NIR cameras is optimized for depth sensing, 3-D mapping, compositional analysis, authentication, and gesture tracking. Spark4K also features dynamic pixel sizing for lower resolution, high sensitivity security applications. Light captured from adjacent 1.1um pixels can be combined to maximize sensitivity and readout speed according to the demands of a specific application. In practice, this allows for an optional 3MP sensor mode with four times greater sensitivity in low light or long-range scenarios.

Spark4K is sampling in June 2016 with mass production scheduled by Q4 2016.

"The challenges to extend photon counting into the visible/nIR wavelengths and achieve energy measurement in the UV with specific read noise requirements are discussed. Pixel flicker and random telegraph noise sources are highlighted along with various methods used in reducing their contribution on the sensor’s read noise floor. Practical requirements for quantum efficiency, charge collection efficiency, and charge transfer efficiency that interfere with photon counting performance are discussed. Lastly we will review current efforts in reducing flicker noise head-on, in hopes to drive read noise substantially below 1 carrier rms."

Invisage Announces 2K SAM Camera

Image Sensors World        Go to the original article...

BusinessWire: InVisage announces its Spark Authentication Module (SAM) NIR camera module. SAM is powered by the previously announced SparkP2 2MP NIR sensor. Sized 8.0 x 8.0 x 3.1 mm, the SAM module is custom built for authentication systems such as Microsoft Windows Hello. In addition to blocking interference from direct sunlight, SAM enables authentication at a greater distance of beyond 100cm from a tablet, laptop or phone so that users are not constrained to a small space in front of their device. Because it operates at the 940nm wavelength, SAM also eliminates an intrusive red glow from LEDs.

SAM is said to be the only system that can deliver 2K resolution in a tiny module while consuming 50 times less system power. Existing NIR cameras operate in conjunction with high wattage LEDs to overcome low CMOS sensitivity and ambient infrared in sunlight. The resulting high power consumption and heat generated by such bright LEDs has made outdoor performance a challenge for mobile face recognition systems that operate with lighter batteries. In contrast, SAM, powered by SparkP2, leverages low-power pulsed LEDs synchronized with an extremely short global shutter exposure, allowing for accurate imaging without battery drain. At 50 times lower power consumption, overall system temperature is also up to 20 degrees cooler.

For authentication, mobile device makers demand compact modules that produce sharp images enabling smooth user verification with minimal false negatives or false positives, regardless of whether the user is indoors or out,” said Jess Lee, InVisage President and CEO. “It also needs to work within a reasonable range so that users can say ‘Hello’ without having to plant their eye or face just a few centimeters from the screen.

With a photosensitive layer 10 times thinner than a typical silicon infrared sensor, the SparkP2 sensor powering SAM provides QE of 35% at 940nm wavelength. This greater sensitivity results in sharper images and an expanded operational radius of beyond 100 centimeters, but it also enables minimal crosstalk in a thinner, 3.1-millimeter module with a 72-deg FOV. IR in particular suffer from blur due to high levels of crosstalk, or misdetection of light in nearby pixels. Crosstalk typically limits camera thinness by requiring a minimum distance between the lens and the photosensitive layer, but the SparkP2 lens in the SAM module can be much closer to the sensor without increasing crosstalk and preserving a higher level of sharpness.

SAM and SparkP2 are optimized for authentication systems that operate at 850nm (with a visible red glow) and 940nm (invisible with a tenfold improvement in sun irradiance rejection).

Rumor: Sony & LG Innotek to Supply Dual Camera Module for iPhone 7

Image Sensors World        Go to the original article...

Barron's quotes Nomura Securities and Citi Research saying that all the new 5.5″ iPhones 7 coming this fall will have dual cameras. Nomura’s Chris Chang thinks Sony is now behind schedule, which means that Apple will have to go to LG Innotek for assembly:

"We think Sony may not be able to deliver its full share of dual cameras to Apple due to: (1) lower-than-expected yield, and (2) damage to its production facility from the April earthquake in Kumamoto. As a result, we think LGI will gain majority share of the initial dual camera orders from Apple...

We expect a sharp increase in camera module ASP from 2H16F as we think: 1) dual camera module is likely to command 2.5x ASP premium vs. single-cam, and 2) OIS (optical image stabilisation) will also be equipped in the new 4.7” iPhones – currently only the 5.5” model has OIS.

Sony Earthquake Impact Estimated at 115b Yen

Image Sensors World        Go to the original article...

Reuters, Sony: Sony estimates the impact from the quake on its image sensor and digital camera operations would total 105 billion yen this business year. It says the impact on the company as a whole would be 115 billion yen. The devices division, which includes image sensors, is to book an operating loss of 40 billion yen, compared with the previous year's loss of 29.3 billion yen. Sony also says, without elaborating, that the expected loss at its devices segment factored in a 30 billion yen loss from cancelling development of some camera modules:

"In addition, Sony decided to terminate the development and manufacturing of high-functionality camera modules for external sale, the mass production of which was being prepared at the Kumamoto Technology Center, as a result of a reconsideration of the strategy of this business from a long-term perspective. Approximately 30 billion yen in expense is expected to be incurred due to this termination."

More Details on SPI Color Night Vision Sensor

Image Sensors World        Go to the original article...

SPI Infrared publishes few more details on its X27 4K color night vision sensor. Few statements from SPI Infrared site:

"Unlike other technologies, the x27 low light color security camera always images full 390-1200Nm without having to switch camera functions, the user always gets the full broadband.

The x27 low light color sensor has extremely large pixel pitch cells for high light gathering capabilities and is very sensitive in the IR spectra region. The high 5 Million equivalent ISO system has outstanding low lux capabilities with a whopping 85,000x luminance gain.

High definition 10 megapixel sensor works in the daytime and accepts a wide array of standard off the shelf commercially available lenses. The X27 low light sensor produces 4K high definition color imagery even at 1 millilux low light levels.

The x27 low light color security camera vastly outperforms any exsisting low light color technology like CMOS, Scmos, CCD, EMCCD, EBAPS and traditional military grade intensified technologies.

Current day CMOS extreme low light color sensors reach a peak maximum quantum detection limit, an inevitable quality to these sensors are RGB or color filters that must reside on the sensor to produce a nice color image, along with other filters that enhance color image quality. These filters cut down photons and sensitivity dramatically, but must be present to produce a nice color image. The Solid-state x27 color low light night vision sensor utilizes specialty video processing on chip and on the filters, as well as advanced electronic vis-nir image enhancement algorithms that allow it to collect an incredible amount of light, and retain full sensitivity without loss of a brilliant color image, furthermore the x27’s BSTFA (Broad Spectrum Thin Film Array) high fidelity, large pixel pitch sensor architecture achieves incredible bright as day, true color imagery at real time full tv frame rates, without image lag and minimal image noise or grain.

Another drawback to traditional sensors is the infrared cut filter, this filter sits in front of the sensor and cuts out all infrared wavelengths which is needed for a good color image. By cutting out the infrared spectrum from the sensor, the camera does not pick up infrared signals which have added benefits to a good night vision image and also cuts the ability to see infrared lasers, pointers, Illuminators and designators. The removal of the infrared cut filter from traditional sensors produce a pink/red image and displays a non optimal picture. The specialized x27 sensor sees well into the infrared region as well as produces a nice true brilliant color image allowing the user to see a full broadband extended dynamic range image that includes visible to infrared wavelengths. The x27 outperforms any low light technology in existence today within the visible to SWIR spectral region.

Back side illumination of chip technology is another area that allows the chip to output higher performance in low light, the x27’s color night vision detectors bsi backside illumination is yet another aspect that makes it desirable for Imaging at never before seen extreme low light conditions. The x27 ultra extreme low light color night vision complementary metal oxide semiconductor (CMOS) integrated circuit (IC) is a vital proven technology.

Albert Theuwissen publishes a blog post explaining a difference between different ways to bin pixels and average them:

"Conclusion : charge domain binning is more efficient in increasing the signal-to-noise ratio compared to binning/averaging in the voltage domain or binning in the digital domain. The explanation of binning and averaging as well as the discussion about signal-to-noise ratio in this blog takes into account that the noise content of the pixel output signals is dominated by readout noise. The story becomes slightly different is the signals are shot-noise limited. This will be explained next time."
