Canon Applies for Curved Edge Sensor Patent

Canon Watch site noticed Egami article on Canon sensor with curved periphery portion, said to improve lens vignetting:

Update: Mirrorless Rumors site posted another patent from Egami , this time applied by Toshiba for a curved sensor:

Tamron Develops 140dB DR Image Sensor

Nikkei: Tamron announces successful development of an innovative image sensor technology, with support of Japan Science and Technology Agency (JST) of National Research and Development Agency, that enhances imaging capability far exceeding that of human vision, featuring ultra-high light sensitivity and WDR.

The new technology is said to enhance both sensitivity and DR, which has been considered difficult in the past. The ultra-high sensitivity enables capturing clear color images even under an extreme low brightness of 0.003 lux, which is darker than starlight. The WDR performance is exceeding 140dB.

Three key technologies - Optics, Image Sensor, and Image Processing - have been identified essential, and their effective integration has been studied for the new imaging technology:

This development is supported by Japan Science and Technology Agency (JST), Adaptable and Seamless Technology transfer Program through Target-driven R&D (A-STEP).

Brigates Publishes Image Sensor Datasheets

Brigates publishes fairly detailed datasheets of its image sensors with characterization data. It's a brave move as some of the parameters are quite far from the state of the art.

BG0703 is a 1MP 1/2.7-inch rolling shutter image sensor aimed to high-end surveillance and industrial imaging markets:

A newer and improved 1080p 1/3-inch BG0803 targets the same market:

Challenges: ST Signs Huge Contract with Apple

French-language site Challenges reports that ST has signed a huge contract with Apple for image sensors, which will boost the workload at its Crolles plants, where fifty new machines are being installed. The influx of this and other new orders allows the Crolles 200mm fab to reach utilization rate of 100%, while Crolles 300mm plant utilization exceeds 80%. When questioned, ST group refused to comment.

Possibly, the French site talks about ST AF ToF sensors used in iPhone 7.

Thanks to SL for the link!

Mediatek to Enter ADAS Vision Solutions Market

MediaTek announces its plan to bring ADAS vision solutions to the automotive industry beginning Q1 2017:

"Reimagined from the ground up, MediaTek’s ADAS system will feature cutting-edge, decentralized Vision Processing Unit (VPU) solutions to optimally handle large amounts of real-time visual streaming data. MediaTek employs Machine Learning to increase the accuracy and speed of detection, recognition and tracking, making it more comparable to human decision-making performance."

Intel to Make SoC for Next Gen Mobileye

Reuters, NYT: Intel will provide a SoC for autonomous vehicle systems that Delphi and Mobileye are developing together, Glen De Vos, Delphi's VP Engineering said. Delphi is testing autonomous driving technology in vehicles in Singapore. By the end of this year, Delphi hopes to choose a city in the United States to launch a test fleet of self-driving cars during 2017, De Vos said. The company is also looking for test site in a European city.

Delphi and Mobileye will demo their self-driving vehicle system at the CES in Las Vegas in January. That system will use current, electromechanical laser imaging technology, or LIDAR, that is too expensive for use in consumer vehicles, he said. Delphi is also working with Quanergy Systems, a maker of solid-state LIDAR systems.

Sony SLDVS-EC Interface

Novus Light discusses Sony proprietary Scalable Low Voltage Signalling with an Embedded Clock (SLVS-EC) interface, which debuts in the company's next generation of image sensors for industrial applications. The interface has been mentioned quite a long time ago in Sony papers such as this one, allowing to output signal independently from 4 corners of the chip:

In SLVS-EC, the clock signal is embedded in the data and recovered by dedicated circuitry on the receive side. Since the signals are then less sensitive to skew, the data can be transmitted at much higher data rates and over much further distances. Each of the SLVDS-EC channels can support speeds of up to 2.304Gbit/sec. The result is that a sensor that supports the new standard will be able to transfer data over eight links at a data rate of 1.84GBytes/sec (80% of full bandwidth due to 8b10b encoding).

I'm not sure what is the difference between MIPI M-PHY and SLVDS-EC, but Sony promotes its high speed:
