We also look forward to more cooperation between the two companies in the future to create more innovative products."

Jianhua Zheng, CTO of MetaSilicon said, “Among the various sensors used in automotive ADAS applications, visual image processing is particularly important. Once the image is not accurate and timely enough, it will directly lead to errors in the judgment of the back-end algorithm, so HDR performance requirements are extremely high. MetaSilicon's LOFIC+DCG HDR technology can achieve an ultra-high dynamic range of 140dB+ to meet practical application needs in the automotive ADAS field. We are honored to work closely with Andes Technology on two high-performance chips, using the world's first ISO 26262 certified RISC-V core N25F-SE that meets the functional safety standards.

VPS Semi presents a 600MP image sensor

From: (Translated to English with Google Translate)

New product release 
VPS800 - New large area array image sensor chip released for wide-area surveillance

On September 6, the 24th China International Optoelectronics Expo kicked off at the Shenzhen Baoan International Convention and Exhibition Center. At this Optoelectronic Expo, Nanjing VPS Semiconductor Technology Co., Ltd. released a new product for the wide-area monitoring field - VPS800 large area array imaging. This series of chips has a pixel count of over 600 million, a pixel size of 0.7 microns, and supports 16 ROIs (regions of interest). It can provide imaging solutions at longer distances and a wider range, expanding the new boundaries of existing wide-area monitoring solutions.

The VPS800 large area array imaging chip is based on the internally-developed vertical charge transfer imaging device (VPS) as the core. It has a single-chip pixel size of more than 600 million, which can solve the problems of complexity, large volume, and high power consumption of existing large area array camera systems. It achieves long range and large field of view while reducing size, weight, power consumption, and cost, allowing coverage of a wider range clearly while obtaining more micro details. Currently, it is mainly used in security monitoring, commercial satellites, industrial inspection, etc. 

For scenarios that require both large-scale observation and the acquisition of a large number of micro-details, the VPS800 large-area image sensor chip can support long-distance fixed-point shooting. With one imaging, large-scale observation can be achieved and the fine details of the entire image can be retained.
For scenarios presenting large target areas and high resolution such as commercial satellite surveillance, imaging sensors are required to be "small" and "light". The VPS800 large-area imaging chip can support a single-chip pixel size of more than 600 million without the need for splicing. It is small in size and light in weight - more in line with the demand scenarios of micro/nano satellites.
It is worth mentioning that the chip supports 16 ROI (Region of Interest) functions, which allows users to read sensor information from any area, thus reducing the amount of information read. The target can be continuously observed through one frame, and it can also achieve multi-target synchronous tracking. It can be used as a supplementary solution to existing security monitoring solutions, expanding the observation scope and application boundaries of existing security monitoring solutions.

Computational Imaging Photon by Photon

Arizona Optical Sciences Colloquium: Andreas Velten, "Computational Imaging Photon by Photon"

Our cameras usually measure light as an analog flux that varies as a function of space and time. This approximation ignores the quantum nature of light which is actually made of discrete photons each of which is collected at a sensor pixel at an instant in time. Single photon cameras have pixels that can detect photons and the timing of their arrival resulting in cameras with unprecedented capabilities. Concepts like motion blur, exposure time, and dynamic range that are essential to conventional cameras do not really apply to single photon sensors. In this presentation I will cover computational imaging capabilities enabled by single photon cameras and their applications.

The extreme time resolution of single photon cameras enables time of flight measurements we use for Non-Line-of-Sight (NLOS) Imaging. NLOS systems reconstruct images of scene using indirect light from reflections off a diffuse relay surface. After illuminating the relay surface with short pulses, the returning light is detected with high time resolution single photon cameras. We thereby capture video of the light propagation in the visible scene and reconstruct images of hidden parts of the scene.

Over the past decade NLOS imaging has seen rapid progress and we can now capture and reconstruct hidden scenes in real time and with high image quality. In this presentation I will give an overview over the imaging using single photon avalanche diodes, reconstruction methods, and applications driving NLOS imaging and provide an outlook for future development.

Andreas Velten is Associate Professor at the Department of Biostatistics and Medical Informatics and the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison and directs the Computational Optics Group. He obtained his PhD with Prof. Jean-Claude Diels in Physics at the University of New Mexico in Albuquerque and was a postdoctoral associate of the Camera Culture Group at the MIT Media Lab. He has included in the MIT TR35 list of the world's top innovators under the age of 35 and is a senior member of NAI, OSA, and SPIE as well as a member of Sigma Xi. He is co-Founder of Onlume, a company that develops surgical imaging systems, and Ubicept, a company developing single photon imaging solutions.
