Samsung Patent application US20160173800 "Image sensor for performing coupling-free readout, and device having the same" by Kyoung Min Koh, Ju Ha Kim, and Jae Cheol Yun talks about the coupling between the column-parallel ADCs:

"A coupling effect is generated between adjacent analog-to-digital converters by parasitic capacitance that is present between the adjacent analog-to-digital converters. In particular, the coupling effect which is increased as a difference between pixels signals becomes large increases non-linearity of each of analog-to-digital converters. The non-linearity is one of sources of errors of an analog-to-digital converter."

Samsung team proposes to change the pixel readout order so that the pixels with similar values read simultaneously:

Yole Développement publishes an interview with SensL CTO Carl Jackson and VP Marketing Wade Appelman. These days, SensL is focusing primarily on LiDAR for ADAS and consumer robotics and drones. Few quotes:

"Our core product is the Silicon Photomultiplier (SiPM). The SiPM is a solid-state sensor that is closely related to SPADs (single photon avalanche diode). A simplistic description of SPAD is a binary photon-activated ‘switch’. An SiPM is formed of a close-packed array of SPADs with a summed output. This summed-matrix of SPADs, that forms the SiPM, acts as a quasi-analog sensor that retains single-photon sensitivity upon a large surface area.

SiPMs have very high internal gain and therefore do not require external amplification that would contribute additional noise to the signal. Therefore the SiPM will have a better SNR than the APD in many use cases.

The histogramming ToF approach reveals the time-correlated photons that would otherwise be lost in the background noise of the ambient light and is used to extract the distance measurement."

e2v announces the Onyx EV76C664 1.3MP global shutter CMOS sensor. The new sensor features an embedded active imaging system which synchronises external illumination and internal electronic shuttering. This allows discernible color images to be produced at extremely low light levels and through diffusing environments (e.g. fog and smoke) by range-gating, making it ideal for Intelligent Traffic Systems (ITS) and security cameras.

The sensor has an innovative 10um-large pixel with extended sensitivity and performance in NIR, and can also cater for ‘all-light’ environments (typical of outdoor camera applications) where wide dynamic range is also needed. The new sensor is available in sparse colour and monochrome filter (EV76C664ACT) and black and white (EV76C664ABT).

EETimes: Rambus presented a poster "Lensless Smart Sensors: Optical and Thermal Sensing for the Internet of Things" at VLSI Symposia 2016. The sensor utilizes a phase anti-symmetric diffraction grating on top of a conventional pixel array and computational algorithms that extract the relevant information from the image.

"In some applications such as range-finding or eye-tracking, it may not even be necessary to reconstruct a full image. Instead, extracting distance measurements may suffice and the particular phase anti-symmetric diffraction structure makes it very simple, explains the poster.

The ultra-low power 2x2mm2 image sensor with a 128x128 pixel array and integrated image change detection circuitry on the same die was enough to measure distances up to 50cm with an error of less than 8%, they reported."

"We do see this as a better, more accurate replacement for head-mounted eye tracking systems like those found in Virtual and Augmented Reality systems. We don’t target the LSS product for remote eye tracking, such as PC display or television based implementations", said Paul Karazuba, Director of Product Marketing for Imaging at Rambus.

SonyAlphaRumors says it got this rumor from the known source:

"Sony is currently prototypeing Image Sensors based on SiOnyx or better known as “black silicon”. Basically it uses a porous silicon etch on the front side to reduce reflectance. However, while this works well in reducing the visible light reflectance of bare silicon wafers with no backside layers or materials from 46 % to a few %. For image sensors a sensitivity invrease of 30% is estimated."

Autosens Conference publishes an interview with Valeo Senior Expert and Adjunct Professor of Automotive Electronics at the University of Ireland Patrick Denny. Few points on image sensor implications:

"The pervasive tendency in the industry is a transition from component-level thinking to system-level, where the products and applications are considerably more than the sum of their parts.

This calls for: glass-to-glass thinking for the video chain (for viewing), and; glass-to-bit appreciation (for machine vision).

These instincts must be further widened in multi-sensor architectures that support sensor fusion to include photon/phonon-to-bit thinking. The day of daisy-chaining black boxes to make an automotive product is gone and stakeholders in the video chain need to have an appreciation of, and accommodation for, the interaction of the elements which originate both inside and outside of the automotive industry."

"A typical colour megapixel automotive camera generates a data bit for every man, woman and child on Earth in under 6 seconds and is connected in turn to multi-sensor systems that perform ever more complex processing, and this is the tip of the data iceberg among the sensor fusion systems on a vehicle.

The introduction of cameras on to vehicles caused a leap in the volume, variety and velocity of data available to the vehicle and a rock solid mathematical appreciation of how these data sets work is vital for automotive technologists trying to make product differentiators."

EETimes publishes an article "Mobileye Chief Engineer Explains EyeQ5" by Junko Yoshida. Few quotes:

"12 to 18 months ago, automakers were more inclined to develop an autonomous car that allows a driver to take his mind off driving on the highway, according to Mobileye. That would be a Level 3 autonomous car – according to the SAE standard -- defined as “within known, limited environments (such as freeways), the driver can safely turn their attention away from driving tasks.”

Now, automakers want autonomous cars that can operate without a driver – much sooner than later, according to Mobileye.

In keeping up with its customers’ more aggressive timetable, Mobileye has also “slightly pulled forward” — to 2020 — its plan for EyeQ5.

[Elchanan Rushinek, Mobileye’s SVP of Engineering] said that EyeQ5 was designed to support more than 16 cameras in addition to multiple radars and LIDARs, including the low-level processing of all sensors.

More at the technical level, he explained, “There are 16 virtual MIPI channels and more than 16 sensors can be supported by multiplexing several physical sensors on a single virtual MIPI channel.”

“Camera processing is the most computationally intensive, so any solution would include dedicated vision processing ECUs in addition to sending some of the raw data to the central ECU. Both EyeQ4 and EyeQ5 can support both goals -- specific vision processing, as well as master ECU,” he added. “The EyeQ controls each sensor via I2C bus on a frame basis in order to get the optimized output, which is deeply aligned with real time algorithms.”
