PRWeb: CogniVue announced the ability of its Image Cognition Processor (ICP) to support always-on vision applications like gesture recognition, face and eye detection in low power smart wearable devices at power levels of ~1mA, enabling vision apps to run for many days as opposed to hours. CogniVue’s APEXTM ICP are said to be better than 100x performance per power vs conventional processing architectures for embedded vision applications. That significant performance per power advantage is paying off in the rapidly accelerating market of smart wearable devices. This advantage will grow as next-generation APEX cores are announced by CogniVue later in 2014.

One of Cognivue customers, NeoLAB Convergence went to production with the Neo 1 smart pen, said to be the smallest and longest lasting smart pen in the market. The pen uses CogniVue 1st generation APEX-based technology and an image sensor both operating at 120fps to render hand writing and hand drawings in real time to a smart phone or tablet or server wirelessly with no perceived delay. It does this at very low power levels, enabling this battery-powered device to last for weeks on a charge. NeoLAB engineers dramatically increased battery life compared to the competition and they were able to go from design start to prototype in as a little as 6 months using CogniVue’s comprehensive software development kit.

EETimes-Europe, EETimes report that the Commercial Court of Paris, France is considering 12 bids for the bankrupted LFoundry wafer fab in Rousset and its assets; one from General Vision Inc. and 11 others from brokers who wish to acquire the fab equipment and sell it on.

General Vision (Petaluma, CA) is a US company led by expatriate French expects in computer vision and neuromorphic computing and which includes Philippe Lambinet, formerly a corporate strategy officer at STMicroelectronics NV and general manager of ST's digital sector. General Vision is proposing to use the Rousset fab to manufacture neuromorphic chips and image sensors on glass substrates in a joint technology development with Japanese Asahi Glass, under a project call NeuroMem. The proposed chips could include a million neurons in a system that would function like the human visual system and recognize objects in visual inspection and robotic applications. General Vision has presented its plan to former employees at Rousset and said that if the liquidator accepts its proposal that it would need 120 employees by the end of 2014. Over the time General Vision hopes to expand its neuromorphic products manufacturing and return the site to the levels of employment when it was shuttered.

Business Wire: Aptina is to acquire CFA processing and probe imaging assets from Micron. In addition, Aptina will lease from Micron the Nampa, Idaho fabrication facility known as Fab 9D where the CFA processing is located. The purchase is expected to close in Q3 2014.

"Our growing revenues and strong financial position have enabled Aptina to purchase these assets and add great people which gives us a strategic advantage in the marketplace," said Phil Carmack, CEO of Aptina. "Our ability to tightly integrate the entire R&D cycle accelerates innovation and enables us to uniquely support our customers."

"The operating advantages of this deal will flow directly to the bottom line," said Tony Alvarez, Chief Operating Officer of Aptina. "The ability to innovate, such as we have done with Aptina Clarity+ technology, and customize CFA will drive growth opportunities in all of our market segments including automotive, mobile and surveillance."

Aptina's blog also publishes Q&A session with Tony Alvarez, COO, Jeff Mendiola, VP of Operations, and Terry Gilton, VP of Advanced Technology, with more details on the acquisition:

Question: Could you share an example where these capabilities help Aptina innovate?
Terry: The best example of Aptina’s prowess in the pixel optical stack development is (Aptina) Clarity+ technology. We would have not succeeded with this program without being very closely involved in the CFA process development and materials evaluations. For the future there are some very unique ideas that we can realize quickly with the CFA/ML teams like super small pixels, new color/material combinations, uniformity improvements and a few others that we don’t want anyone to know about yet!

Seeking Alpha publishes Q&A session from Himax Q1 2014 earnings call. Few interesting quotes:

Jerry Su – Credit Suisse AG:

Is there a significant turnaround on your on several subsidiaries specific non driver – non-driver product lines?

Jackie Chang, CFO:

"Yes, LCOS company and also the Himax Imaging Technology that is the CMOS imaging sensor region that is still losing money. But we do expect one or both of them breaking even or be profitable this year."

Daniel A. Heyler – Bank of America Merrill Lynch:

Could you elaborate on the products, you just mentioning eight megapixel. Is that a BSI product – BSI technology or is that going to start on a FSI.

Jordan Wu, CEO:

The major BSI product we’re launching eight megapixel, which is really getting enjoying growing popularity design wise with customers... And later in the year we are going to launch around 1 megapixel BSI sensor for laptop and tablet, which is a full HD sensor. So that will likely be our second BSI product.

Daniel A. Heyler – Bank of America Merrill Lynch:

So is the eight megapixel BSI, is that currently shipping in volume or is that a third quarter ramp?

Jordan Wu, CEO:

No, it’s a third quarter thing, starting of third quarter. It’s going through design stage.

Daniel A. Heyler – Bank of America Merrill Lynch:

And is that on 12-inch wafer or is that going to be on 8-inch because I know capacity is pretty tight on 8-inch?

Jordan Wu, CEO:

No, it’s 8-inch, but TSMC has – we will agree upon to capacity reservation with TSMC. So I think we all can.

Aptina's patent application US20140125838 "Imaging systems with modified clear image pixels" by Jeffrey Mackey, Gershon Rosenblum, and Alexandre Dokoutchaev proposes an improvement over the previously published Clarity+ application. The necessity for the improvement is explained as: "Some imaging systems replace the green color filters in the standard Bayer mosaic pattern by a non-absorbing clear material. This type of clear pixel can boost the sensor light sensitivity by a factor of more than two, thereby significantly improving the medium and low-light performance. However, this type of color scheme is partially subtractive and therefore can require the use of relatively high color correction coefficients. In addition, the high sensitivity of the clear pixel can result in a color channel imbalance that is typically corrected using relatively high white-balance coefficients. Thus, if care is not taken, proper color correction using these types of color correction and white-balance coefficients can result in an enhancement of pixel noise."

The solution is to modify the clear pixel: "Image pixels 190 may include modified clear pixels. For example, some of pixels 190 may include color filter elements formed from transparent material with a color additive such as a yellow pigment or other similarly shaded pigment or dye. The pigment may be added to the transparent color filter element material in concentrations configured to give desired spectral filtration qualities to an otherwise uniformly transparent color filter array pixel."

The processing pipeline with Clear pixel modified into Yellow is quite similar to the original, where C (clear) is changed to Y:

ResearchInChina releases its updated "Global and China CMOS Camera Modules Industry Report, 2013-2014." Few interesting statements from the report:

"In Chinese mobile phone market, 8MP will be replaced by 13MP which has become the standard configuration of mobile phones priced at RMB1,000 or above in 2014. Chinese brands use 13MP more widely than foreign brands. The mobile phones made in China are always featured with high-end hardware configuration. 30% of the domestic mobile phones will be equipped with 13MP in the first half of 2014 and about 50% by the end of 2014 (exported ones are excluded). Both of rear and front cameras have higher and higher pixels. 5MP front cameras are the current mainstream, while the mobile phones with 13MP front cameras have been launched."

"In 2013, the CMOS image sensor shipment reached 3.26 billion units at an increase of 15.2%, and the market size hit approximately USD8.008 billion. The shipment is expected to rise by 16% to 3.782 billion units, and the market size will be USD8.698 billion or so in 2014."

"Japan Konica-Minolta is the first one that exits from the fields of CMOS camera modules and mobile phone cameras due to unbearable falling profits. O-film, a company in Mainland China, has invested RMB2 billion in CMOS camera modules. As the world's largest film-based touch screen vendor, O-film has extensive customer resources, and it intends to enter the CMOS camera module field with competitive prices in order to become the largest camera module company in Mainland China. O-film’s gross margin was less than 6% in 2013."

"Largan nearly monopolizes the non-Korean 13MP camera market which is characterized with high technical threshold and high patent threshold, occupying an unparalleled position. The second-ranked Genius suffered losses in 2013. In 2014, Sunny acquired the assets of Konica-Minolta in Shanghai, so that its optical lens technology is expected to be greatly improved, but it still can not threaten Largan. Largan continues capacity expansion in 2014, but mainly in Taiwan, and it will cut down the capacity in Mainland China owing to labor costs."

SeekingAlpha publishes TowerJazz Q1 2014 earnings call transcript from May 15, 2014 where CEO, Russell Ellwanger, updates on Panasonic CIS process availability on the foundry basis:

"If we look at progress that has been made so far on the foundry side of this venture and the CMOS image sensor business unit, we have made major steps forwards through the TowerJazz Panasonic deal. As was already mentioned last quarter, Panasonic, now TPSC, does have this worldwide leading CIS technology at 65 nanometer 300 millimeter wafers. This, combined with the reputation TowerJazz has in the image sensor business, allowed us to engage with several customers already on markets that were not accessible to TowerJazz until now such as very high-end cellphone camera markets and high-end digital SOI markets. We have prepared with our partners at TPSC, a foundry match PDK for 1.12-micron state of the art pixel technology and it’s now released to selected customers who already started their designs.

In parallel, we are preparing a unified CIS PDK that will be our mainstream PDK for the CIS 65 nanometer process and already includes 20% photomask reduction against the present flow. This process design kit is targeted for all pixels having dimensions larger than 1.35 micron for many types of applications, including obviously the digital SOI market. This design kit is going to be released to our customers by middle of next month and we have already many inquiries for data on this process for specific products by a variety of customers. Hence TowerJazz Panasonic Semiconductor Company allows us not only to increase our market share within our customer base by allowing them to get into new markets and applications, but also allows us to acquire new customers."

Russell Ellwanger says on the current state of the business:

"The CMOS image sensor business continues to grow in all fronts, namely high-end broadcasting and cinematography, industrial camera, medical x-ray sensors and gesture control. We see high demand for current products, higher than our forecast from the beginning of the year and an increase in new product tape outs. As we previously stated, we expect strong wafer based strong revenue growth starting Q4 this year and wrapping through 2015 in the gesture control application.

In our U.S aerospace and defense business unit, we continue to see revenue growth. In part this is due to increased R&D spending from our customers. An example was announced this quarter with a multimillion dollar award to TowerJazz from the US Air Force Research Laboratory towards a program directed at the manufacture of advanced read-out ICs which are used in many commercial and military sensors, detectors and imaging systems. We continue to build out more capacity and progress with our customer partner in our annex for the manufacture of commercial infrared sensors. We expect to see these turn to very strong wafer based revenue over the next years."
