Image Sensors 2013 Calls for Papers

...

PRLog: Image Sensors 2012 (London, UK conference) announcs the Call for Papers for IS2013. It seems that the conference has the new owner, Smithers.

The IS2013 is planned to cover the following applications in image sensor technology:

• Automotive imaging
• Digital Still Cameras
• Machine Vision
• Time-of-flight and 3D imaging
• Metrology
• Low light level imaging

The conference will also feature an 'Expert Panel' session to discuss some of the pressing issues facing the sector, and an 'Innovation Platform' session to give academics, spin-outs, and SMEs an opportunity to present their latest innovations to the audience.

A short summary of the proposed presentation (max 500 words), plus a speaker biography can be submitted to rstead@smithers.com by 26th October 2012.

Sony Abandons "RGBW Coding" in Stacked Sensors

...

Sony announced announced specification changes to its Stacked CMOS Image Sensors IMX135 and IMX134 and the camera modules based on these sensors, IU135F3-Z and IU134F9-Z, which are scheduled for phased launch starting January 2013.

Sony will switch their color coding to a RGB instead of originally announced "RGB-W coding", as it has failed to meet "certain conditions of Sony's image quality standards".

Sony also changed the sensitivity specs (typical value F5.6): 92mV (Green pixel) and 127mV (White pixel) changed to 84mV (Green pixel).

Digitimes: Samsung Gains Market in China

...

Digitimes quotes Samsung distributor in China expecting revenue increase in September on orders for Samsung's image sensors from local smartphone makers.

Some local smartphone vendors are said to be switching to Samsung image sensors as Sony's and Omnivision's production capacities have been fully booked by Apple, according to Digitimes' sources. The distributor expects to deliver up to five million sensors to these customers in September, according to Digitimes' sources calculations.

More Details on Panasonic 1.12um SmartFSI Pixel

...

It appears that most of the previous articles quote Panasonic PR in Japanese from Sept. 20. The PR has few other interesting claims:

• Panasonic contemplates release of 14MP and 16MP models based on the same 1.12um SmartFSI pixel.
• The angle of incidence is quoted as 40deg due to advanced light guide (see figure below)
• The module height can be reduced down to 70% of that with BSI sensors

The lightpipe figure has all the explanation in Japanese, embedded in the image. Google translator is helpless here. It would be great if somebody can translate it:

Panasonic also published a higher resolution view of microlens array:

Update: Thanks to TN for translating the picture:

Panasonic to Launch 1.12um FSI Pixel

...

Tech-On published more details about Panasonics's oncoming 13MP sensor for smartphones. The sensor format is 1/3.06-inch, meaning the pixel size of about 1.1um. It belongs to its SmartFSI family. This makes Panasonic the only company talking about a non-BSI 1.1um pixel.

The new pixel sensitivity is said to be the highest in the industry at 3,230e-/lx/sec/sq.um. Panasonic claims it has improved S/N ratio by a factor of two. A "light-concentrating structure" improves the new pixel's color reproducibility and angular response.

Another three new features of the sensor, as quoted by Tech-On:

• high-sensitivity photo diode: wide, deep photo diodes in small pixels
• microfabrication technology, which reduces parasitic capacitance for improving the sensitivity of in-pixel amplifier and reducing the noise of transistor
• optimal matching design technology for the lens of camera module and the light-concentrating structure developed by Panasonic

While the initial look has not revealed the Apple iPhone 5 primary sensor part number, Chipworks found "a lonely little "SONY" mark on the sensor. The measured pixel size is 1.4um, same as in iPhone 4S:

The front camera's sensor has been identified as Omnivision's:

Ambarella Announces 4K IP Camera SoC Family

...

Ambarella introduces S2,a security IP camera SoC with support for the new 4K Ultra HD video standard, based on a Dual Core ARM Cortex-A9 CPU and a high-performance video engine that delivers multi-stream H.264 encoding up to 4K (3840x2160p30) resolution. Hardware analytics acceleration enables cameras to analyze video content and make intelligent decisions based upon it. Using low-power 32nm process, the S2 delivers 1080p60 encoding in less than one Watt and 4K video encoding in less than two Watts.

"By delivering 4K video and multi-core CPU performance in a 32nm low-power design, Ambarella is enabling high resolution video in compact camera form factors," said Fermi Wang, President & CEO of Ambarella.

The S2 family provides an array of IP camera design choices. The family is comprised of software and pin-compatible SoCs that range in performance from 1080p45 encode with a 500 MHz dual-core CPU to 4K Ultra HD encode with a 1 GHz dual-core CPU. Its advanced features include panoramic lens de-warping, hardware face detection, digital PTZ and EIS. The Linux based SDK supports a wide range of image sensors and enables features such as WiFi connectivity, cloud services, local SD Card recording and transcoding. The SDK also offers comprehensive 3A and image tuning tools for customization.

S2 Feature Summary:

• Image Sensor Pipeline with high-speed SLVDS/MIPI®/HiSPi™ interfaces, up to 32 Megapixel (MP) sensor resolution.
• Wide Dynamic Range (WDR) with multi-exposure fusion to improve video in high-contrast lighting conditions.
• Advanced 3D noise reduction with de-ghosting to enhance low-light performance.
• 4K video (3840x2160p30 or 1920x1080p120) H.264 encoding to support the new Ultra HD standard. Multi-streaming to enable independent resolutions, frame rate and quality. Support is also offered for video transcoding and low-latency encoding.
• Dual Core ARM Cortex-A9 CPU with NEON and a 512 KB L2 cache provides headroom for customers’ applications, as well as enhanced power efficiency and real-time performance compared to single-core architectures.
• Analytics hardware acceleration for efficient processing of tasks like object tracking, trip zone perimeter control and intelligent motion detection.
• Real-time hardware-accelerated de-warping for 180/360 degree panoramic lenses.
• AES/3DES/SHA-1/MD5 encryption engines.
• Interfaces includes32-bit DDR3L, Gigabit Ethernet, USBG 2.0 host and device, HDMI®, SDXC SD™ Card, and dual sensor interfaces.

The S2 family of SoCs is available now for qualified customers.

Panasonic to Launch 13.4MP Sensor for Smartphones

...

Jiji Press quotes Panasonic announcing today that in December it will launch production of a the new 13.4MP image sensor for smartphones and other mobile devices. The sensor is said to use "semiconductor microfabrication technology to curb image noise". It is going to be one of the thinnest image sensors in the industry so it can be used in very thin smartphones and tablets, Panasonic said.

Pixart Sales for Nintendo Wii U to Reach 20% of Total

...

Digitimes expects Pixart to report Q3 results meeting its guidance for a 40-50% on-quarter growth, fueled by Nintendo's Wii U console sensors.

Shipments of sensors for Wii U are expected to reach NT$200 million (US$6.8 million) or 20% of Pixart's total sales in the third quarter, according to Digitimes' sources. The Wii's shipments are likely to peak in October and then begin slowing down due to fierce competition in the gaming sector and a lack of new attractive software delivered by the Wii U, the sources commented.
