BBC reports that Intel has revealed a version of its 3D depth camera that is small and thin enough to fit into a 6-inch screen smartphone. The prototype was unveiled by the company CEO Brian Krzanich at an event in Shenzhen, China, although he did not demonstrate it working. The RealSense sensor can be used to recognise hand and head movements and makes it possible to change the focus of photos after they have been taken.


The official Intel PR says "Krzanich discussed how Intel RealSense cameras can provide intuitive, vision-based capabilities for solving complex problems and delivering exciting new usages and capabilities across a variety of form factors. To that end, he showed for the first time a 6-inch smartphone prototype with a new, longer-range Intel RealSense camera built into the device."

Sony announces its plans to increase its production capacity for stacked CMOS image sensors in the fiscal year ending March 31, 2016 ("FY15"). This investment is intended primarily to augment production facilities used in the mastering processes and layering and futher downstream processes for stacked CMOS image sensors at Sony Semiconductor's Nagasaki Technology Center ("Nagasaki TEC") and Yamagata Technology Center ("Yamagata TEC"). The mastering process refers to the manufacture of photodiodes and wiring processes for stacked CMOS image sensors. The layering process refers to the layering of semiconductor chips containing back-illuminated structure pixels on top of semiconductor chips containing the circuit for signal processing.

With investments such as the one announced in February and this supplementary investment, Sony plans to increase total production capacity for image sensors from the current level of approximately 60,000 12-inch wafers per month to the level of approximately 87,000 wafers per month by the end of September 2016. The total additional investment amount is projected to be approximately 45 billion yen, comprising approximately 24 billion yen of investments in Nagasaki TEC and approximately 21 billion yen of investments in Yamagata TEC.

Toshiba Corporate R&D announces "a super high quality image processing technology that achieves image quality comparable to that of larger image sensors." The number of pixels in image sensors has been increasing year by year. However, the size of image sensors has not changed and this leads to increase of noise in the image because the amount of light received per pixel decreases as the pixel count increases. The long time exposure reduces image noise, but the image quality suffers due to camera shake. Conventionally, electronic image stabilization technology has been used to prevent image quality deterioration. In electronic image stabilization, several copies of the image are overlaid to compensate for the noise and a large amount of parallel memory is required to hold the multiple image copies. As a consequence, the noise reduction effect is limited by the number of image copies that can be kept in memory.

Toshiba has developed the processing technology significantly reducing noise and preventing camera shake without requiring a large amount of memory. This technology is said to generate a very sharp image with less noise by overlaying many continuously recorded images. The image is sequentially generated using the memory capacity required for just a single image. This new technology is said to effectively and precisely detect everything from tiny vibrations to large camera shake. Random noise is said to be canceled out by overlaying multiple images, and object edges are kept clear and crisp through the same process. The increase in the number of captured images makes it possible to obtain very high image quality using very little memory for storage. In particular, the technology is said to enable the users to produce extremely clear images at low light conditions.

Caltech presents its paper "Nanophotonic coherent imager" by Firooz Aflatouni, Behrooz Abiri, Angad Rekhi, and Ali Hajimiri published in Optics Express. The 4 x 4 pixel imager is utilizes a coherent LIDAR principle and is said to be able to resolve 15um depth difference at 0.5m distance.

"By having an array of tiny LIDARs on our coherent imager, we can simultaneously image different parts of an object or a scene without the need for any mechanical movements within the imager. By coupling, confining, and processing the reflected light in small pipes on a silicon chip, we were able to scale each LIDAR element down to just a couple of hundred microns in size—small enough that we can form an array of 16 of these coherent detectors on an active area of 300 microns by 300 microns," says Ali Hajimiri. In the future, Hajimiri says, that the current array of 16 pixels could also be easily scaled up to hundreds of thousands.

Pelican Imaging patent application US20150091900 "Systems and Methods for Depth-Assisted Perspective Distortion Correction" by Samuel Yang, Manohar Srikanth, Dan Lelescu, and Kartik Venkataraman proposes a solution to the common selfie problem:

"Close range portraiture photographs, such as self-portraits, are often perceived as having apparent perspective distortions at typical image viewing distances, even if the optics produce a geometrically accurate perspective projection of the scene. A mismatch in the field of view of the camera and that of the viewing display configuration can result in the perceived distortion, which in portraiture photographs, tends to magnify the size of the nose and chin, among other features. These distortions are especially common with photographs taken with mobile device cameras due to the wide angular field of view typical of such cameras and close range nature of many self-portraits and candid portraits."

Pelican proposes to use the depth information to post-process the image and fix the distortions:

PR Newswire: As has been reported earlier, a settlement between Lead Plaintiffs and OmniVision, Shaw Hong, Anson Chan, and Aurelio "Ray" Cisneros (the "Individual Defendants" and collectively, with OmniVision, the "Defendants") in the amount of $12,500,000 has been proposed by the Settling Parties. A hearing will be held before the United States District Judge on June 5, 2015.

Meanwhile, SeekingAlpha speculates about the chances that Omnivision buyout deal goes through:

"Officers and directors, as a group, own less than 5% of the company, and don't appear to be personally incentivized toward a sale. (CEO Shaw Hong, for instance, would earn profit about $2.7 million off a sale at $30, relative to current prices. His annual compensation has averaged $3.9 million over the last three years.)

In addition, it's not at all clear that such a buyout could get done. The federal government's Committee on Foreign Investment in the U.S. (CFIUS) would likely be involved, and at least one expert sees the combination of foreign ownership and the inclusion of state-owned Shanghai Pudong Science as being a potential roadblock. An agreement now or in the near future could see the approval process run into the 2016 elections, when, as Derek Scissors told Barron's, "the general economic mood is anti-foreign and certainly anti-China."

Micro Market Monitor: The South American image sensor market, mainly driven by the increasing demand for cameras in smartphones and tablets, along with the increasing application of image sensors in the South American medical diagnostic and image sensor market was estimated to be $622.3 million in 2014 and is projected to reach $1,053.6 million by 2019 at a CAGR of 11.1% from 2014 to 2019.

Engadget, Business Insider, Newsweek: The same group Science for the Masses that has shown the human vision extension to IR, now publishes another experiment showing night vision improvement with eyedrops. The group used Chlorin e6 cancer treatment substance mixed with insulin for their experiment. They claim that the eyedrops significantly enhance night time vision at distances up to 50 meters for a time of few hours.

The experimenter, Gabriel Licina describes his feelings "It’s subtle. It’s not like ‘oh my gosh I have super vision!’ It’s more like dark became dim, everything was a little brighter. Not a crazy noticeable light, burning and doom, but more a subtle, ‘oh I can see a thing!"

The adverse effects of the proposed solution have not been studied.

Point Grey confirms that Sony will discontinue operations of their CCD 200mm wafer line at Kagoshima Technology Center in Japan by the end of March 2017. This line is responsible for production of all Sony CCD image sensors used in Point Grey cameras. Point Grey did not confirm exact last-time buy (LTB) or last-time ship (LTS) dates for the affected CCDs, commenting that recently publicized dates of August 2015 and March 2020, respectively, should not be considered final. “Point Grey has been actively discussing details about the closure directly with Sony,” said Michael Gibbons, Director of Sales and Marketing at Point Grey. “This is a very dynamic situation and final details, including official last-time buy and ship dates, have not yet been released publicly by Sony. We caution our customers against making quick decisions based on preliminary information circulating the Internet.”

Point Grey continues to see high and growing demand worldwide for both CCD and CMOS sensor technology, and believes that CCD technology will continue to play an important part in the imaging world for many years to come. “Our goal is to provide customers with three options,” said Gibbons. “First is to continue to buy their existing Sony CCD-based cameras for the natural lifespan of the systems they’re designed into. If customers are happy with these products there is no need to change. For those customers who still prefer CCD technology but want to explore alternatives to Sony, we are actively adding new CCDs from suppliers such as Sharp into our camera lineup. And finally, for those customers interested in the benefits of CMOS technology, we will continue to lead the charge in integrating image sensors from companies like Sony and On Semi into our products.”
