Sony Image Sensor Split "is both expected and surprising"

Image Sensors World        Go to the original article...

CCTV News quotes IHS analyst Brian O'Rourke giving Sony image sensor market share numbers for Q2 2015:


Sony image sensor business spin-off is called "both expected and surprising at the same time. Over the past two years, Sony has spun out its audio and video business (February 2015), and its TV and PC businesses (February 2014). However, the semiconductor spin out is different. While the TV, PC and A/V businesses had been struggling to some extent with increased competition and a slow-growing world economy, the semiconductor business has generated a significant amount of Sony's recent revenues and profitability. The semiconductor business is highlighted by image sensors, a historically successful and profitable business for Sony.
...
Today, it dominates the CMOS image sensor business, with Q2 2015 revenues of slightly over USD1 billion, good for over 42% of the worldwide market, nearly three times the revenue of its closest competitor, Samsung Electronics.
...
Why interfere with a good thing? The current Sony corporate structure seemed to be working well enough to ensure image sensor success. How will the new Sony Semiconductor Solutions benefit the image sensor business? The answer may be in simplifying a corporate structure so that Sony can react more rapidly.

LensVector Lens Has Reached the Market

Image Sensors World        Go to the original article...

PRNewswire: LensVector announces that its liquid crystal autofocus lens, LV4522, has made its retail debut through a partnership with Sunny Opotech and Vital Mobile.

LV4522 uses proprietary technology to transform a liquid crystal cell into a variable focus lens, said to consume about 80% less power than the traditional mechanical lens currently used in mobile devices. Since the device does not use any moving parts, manufacturing LV4522 costs about half as much as it does to manufacture voice-coil motors and is inherently more reliable. Additionally, each module is seamlessly integrated into each smartphone, not requiring individual adjustment or tuning by the handset manufacturer.

LensVector has made initial shipments though its partnership with production partner Sunny Optical to Vital Mobile, which is currently selling LV4522-enabled phones in Taiwan, Bangladesh and India under the Karbonn brand.

As LV4522 ships, LensVector is preparing to ship its next-generation lens by year's end, which provides dramatically higher image resolution, twice the focusing speed of most mechanical lenses, and a minimum focus distance of just 5cm, half the distance of most existing lenses used in mobile devices.

The current lens and the next-generation lens are based on patented technology that transforms a liquid crystal cell into a variable focus lens using small electrical charges to dynamically change the refractive index of the lens material:

Socionext ISP Supports HDR, PDAF

Image Sensors World        Go to the original article...

PRNewswire: Socionext, the company created by merging of Fujitsu and Panasonic semiconductor businesses, announces a volume production of MB86S29, a 'camera front engine' specialized for Bayer data processing with new functions supporting the latest image sensors.

The MB86S29 is the newest Milbeaut Image Processor for smartphones. By accommodating new functionalities of the latest image sensors, the MB86S29 lets module makers implement these functions without replacing their application processors.

Recently, it is common to find cameras in smartphones or other mobile devices that are configured with application processors (AP) equipped with built-in ISP functionalities. These APs can directly process output from image sensors, and help reduce the footprint and cost of camera modules. The MB86S29 supports this trend as a "Camera Front Engine" that replaces conventional ISPs. Connected in between an image sensor and an AP, it is specialized for Bayer data processing, so users can configure their APs with the same interface directory connected to image sensors, and to make full use of PDAF and HDR.

The MB86S29 has 4 lanes each of 2.1Gbps MIPI Rx / Tx. It can process 16MP images at 30 fps. It is also applicable for noise reduction, shading correction, and 3A (AE / AF / AWB) detection. It is available in the smallest package of any member of the Milbeaut series, at 4mm x 4mm.

The MB86S29 has been designed to utilize "Hybrid AF", which combines the accuracy of contrast AF and the speed of phase detect AF, enabling maximum 4x faster AF, in comparison with the previous Milbeaut products. Low power consumption is just 310mW when processing phase detect AF.


The MB86S29 also supports Sensor HDR. Conventional HDR imaging, which generates a picture from multiple frames taken with different exposures, has disadvantages, such as image blurs caused by the difference between the frames, and time needed to take those multiple frames. The MB86S29 can process data with different exposure settings within one image so it can process the HDR images with higher visibility in 16MP, at the speed of 30 fps.


MB86S29 Specifications

  • 16MP at 30fps, Bayer Output
  • Compatible with PDAF Sensors
  • Compatible with Sensor HDR
  • Defective Pixel Correction (including pixels for PDAF)
  • Shading Correction
  • Package: 4mm x 4mm
  • MIPI-Rx: 4 lanes (2.1Gbps) + 2 lanes (1.5Gbps)
  • MIPI-Tx: 4 lans (2.1Gbps)
  • Dual ARM processor Core

The new MB86S29 is available for $3.00 each when purchased in volume quantities of 5 Million pieces or more.

Toshiba’s 2MP Sensor for Vehicles Mitigates LED Flicker

Image Sensors World        Go to the original article...

BusinessWire: Toshiba announces that it has developed a new 2MP CMOS sensor for automotive cameras, CSA02M00PB, equipped with the industry’s first LED flicker mitigation function (first for 2MP sensors). Sample shipments start in March, 2016.

The new 2MP sensor is equipped with Toshiba’s original LED flicker (pulsed LED) mitigation circuit to minimize image flicker caused by LED light sources. When recording LED traffic lights and signs with conventional CMOS sensors, the output images often flickers, preventing an accurate sensing function. Toshiba’s new sensor mitigates the flicker and delivers clear images for faster, more accurate image sensing.

The sensor also adopts Toshiba’s original next-generation HDR system and BSI process. Toshiba’s next-generation HDR system uses the company’s single frame method for clear images free of the degraded resolution and blown-out highlights typical of high contrast-light conditions. Later in the PR, Toshiba talks about different exposure times in a frame: "The maximum frame rate may change per operating conditions specified. Exposure condition 1 assumes 2 different exposure times in a frame; exposure condition 2 assumes 3."

The BSI process is said to be first brought to automotive image sensors by Toshiba. In July 2015, ON Semi too announced its automotive BSI sensor.

The new sensor integrates functions to meet the requirements of ASIL, the Automotive Safety Integrity Level intended to protect life, and supports failure detection, report flagging and control of vehicles. It is also compliant with AEC-Q100 (Grade 2) and is suited both for front end sensing cameras for the ADAS and the latest viewing applications, such as e-Mirror and CMS (Camera Monitor System).

Toshiba foresees three-fold growth in the automotive CMOS image sensor market in the period to 2020. Toshiba will continue to develop its automotive CMOS sensor business to fully meet expanding market requirements.

Orbbec Presents 3D Cameras

Image Sensors World        Go to the original article...

Orbbec presents Astra Pro, a 3D camera with 720p high-definition color, and Persee, said to be the world’s first 3D camera with a fully functioning computer. The devices are first available to supporters of the Orbbec Indiegogo campaign. The Indiegogo campaign will raise funds to mass produce and ship Astra Pro by the end of the year and Persee in early 2016. The cameras have been pre-announced in May 2015.

We believe that the future of computing is 3D and all consumer devices will include 3D cameras in the near future,” said Yuanhao (Howard) Huang, founder and CEO of Orbbec. “Achieving this vision requires superb 3D cameras that are affordably priced and universally available. It also requires a world-class hardware and development platform, which we are delivering with Orbbec Persee.

Orbbec camera features:
  • Highest Resolution – With smoother gradients, precise contours, and the ability to filter out low-quality depth pixels in a way other cameras cannot, Orbbec 3D cameras are suitable for 3D scanning and point cloud development.
  • Longest Range – With a range of 0.4m - 8m, Orbbec 3D cameras are intended for a wide range of scenarios, including gesture control, robotics, 3D scanning, and many new areas.
  • Exceptional Accuracy – Orbbec 3D cameras offer depth measurement accurate to within 0.5 centimeters at a distance of 2 meters.
  • Lowest Latency –Astra Pro is said to be the most responsive 3D camera on the market today.
So far, Orbbec published two patent applications on its 3D camera design: WO2014135127 and WO2014135128. The English abstract of the later application "DYNAMIC PHASE ACQUIRING DEVICE" by HUANG Yuanhao says:


"Provided is a dynamic phase acquiring device, comprising: a light-acquisition port (1), a semi-reflective semi-transmitting lens (2), a phase shifter (3), a polarizer (4), a planar mirror (5), a photo-sensitive element (6), and a phase processor (7); the acquired light passes through the light-acquisition port and reaches the semi-reflective semi-transmitting lens, and then follows two paths: one path sequentially passes through the phase shifter, the polarizer, and the photo-sensitive element, forming a first image; the other path is reflected by the planar mirror and then directly passes through the polarizer and reaches the photo-sensitive element, forming a second image; the pixels of the first image are in one-to-one correspondence with the pixels of the second image; the photo-sensitive element is connected to the phase processor; the photo-sensitive element transmits the first and second images to the phase processor, and the phase processor generates phase data; the phase shifter provides phase lead or phase lag ranging from 1 degree to 20 degrees. By using the phase shifter to provide a lead or a lag by a small angle, such as from 1 to 20 degrees, or even from 5 to 10 degrees, phase data can be obtained via two-path image detection, thus eliminating the need for optical elements for at least one path detection, and thereby simplifying the structure and reducing costs."

Cambridge Mechatronics Technology to Benefit from Mass OIS Adoption

Image Sensors World        Go to the original article...

SeekingAlpha predicts that Cambridge Mechatronics smart alloy OIS actuators (SMA) is set to benefit from mass adoption of OIS in smartphones. The main sign is that its manufacturing Cambridge Mechatronics with Hutchinson Technology have partnered with New Shicoh, China's largest producer of auto-focus camera actuators.

"This is significant because SMA technology is much cheaper to manufacture than its counterpart, VCM technology, and more importantly, it's much thinner. The best point of reference is the iPhone 6, which uses a VCM OIS actuator in the camera and has a large bump on the back of the phone. As SMA technology goes mainstream, the camera bump goes away, and HTCH is the sole manufacturer of that product.

There's no question about the demand for the product. In addition to the issue of thickness on the back camera, there's the issue of the front camera. Currently, there are no smartphones on the market with an OIS camera on the front because of the thickness. The selfie craze has consumers demanding better cameras on the front of the phone, and with SMA technology, that is finally possible.

QIS Breakthrough Announced

Image Sensors World        Go to the original article...

EurekaAlert: Dartmouth's Thayer School of Engineering press release presents "an innovation that may usher in the next generation of light sensing technology with potential applications in scientific research and cellphone photography.

Thayer professor Eric Fossum -- the engineer and physicist who invented the CMOS image sensor used in nearly all cellphone and digital cameras, webcams, medical imaging and other applications -- joined with Thayer PhD candidate Jiaju Ma in developing pixels for the new Quanta Image Sensor (QIS).
"

"Their new sensor has the capability to significantly enhance low-light sensitivity. This is particularly important in applications such as "security cameras, astronomy, or life science imaging (like seeing how cells react under a microscope), where there's only just a few photons," says Fossum. "When we build an image sensor, we build a chip that is also sensitive to these photons. We were able to build a new kind of pixel with a sensitivity so high we could see one electron above all the background noise."

"The new pixels are considerably smaller than regular pixels since they are designed to sense only one photon, but many more are placed on the sensor to capture the same amount of total photons from the image. "We'd like to have 1 billion pixels on the sensor and we'll still keep the sensor the same size," says Ma."

"We deliberately wanted to invent it in way that is almost completely compatible with today's CMOS image sensor technology so it's easy for industry to adopt it," says Fossum. Engineering its size is a step in that direction.

"The question was how to build this in a current, commercially accessible, not-too-expensive CMOS process." he says. "You use all the tricks you can think of. Being able to measure one electron is fundamental from a scientific point of view and we were able to do it without a 'Manhattan Project'." Other challenges his group is working on are in reading out a billion pixels hundreds or thousands of time each second without dissipating too much heat, and also in creating images from all the data that is collected.

PRNewswire: OmniVision announces the OV2281, a new PureCel sensor to implement a biometric security functionality mobile devices. The low-power, ultra-compact OV2281 leverages 1.12-micron pixel and optimized IR sensitivity. It enables reliable iris recognition for smartphones, tablets and notebooks, in both landscape and portrait orientations.

"With the convergence of digital identities, security concerns and mobile commerce, industry experts project that 13 billion biometric applications will be downloaded by 2.2 billion mobile users between 2014 and 2020, [according to Acuity Market Intelligence report]" said Archie de Guzman, staff product manager at OmniVision. "In this context, iris detection appears poised to become the next trend in biometric security for mobile devices. The OV2281 therefore enters the market as an extremely compelling solution by offering accurate horizontal or vertical iris detection in a compact and power-efficient package."

The 1/7.5-inch OV2281 PureCel sensor can record 1080p high-definition video at 60fps in both portrait and landscape orientation, thus supporting iris detection in either situation. When recording full-resolution 1920 x 1920 video at 30fps, the sensor requires just 120 mW. It also supports an ultra-low power mode that can reduce power consumption to approximately 25 mW. As a monochrome sensor, the OV2281 boasts exceptional IR sensitivity. This sensitivity allows it to produce clear and fully stable images in difficult low-light conditions.

The sensor fits into a 5.5 x 5.5 mm module with a z-height of less than 4.5 mm. The OV2281 is currently in volume production.
