ETH Zurich publishes "ESL: Event-based Structured Light" project page by M. Muglikar, G. Gallego, and D. Scaramuzza."We propose a novel structured-light system using an event camera to tackle the problem of accurate and high-speed depth sensing. Our setup consists of an event camera and a laser-point projector that uniformly illuminates the scene in a raster scanning pattern during 16 ms. Previous methods match events independently of each other, and so they deliver noisy depth estimates at high scanning speeds in the presence of signal latency and jitter. In contrast, we optimize an energy function designed to exploit event correlations, called spatio-temporal consistency. The resulting method is robust to event jitter and therefore performs better at higher scanning speeds. Experiments demonstrate that our method can deal with high-speed motion and outperform state-of-the-art 3D reconstruction methods based on event cameras, reducing the RMSE by 83% on average, for the same acquisition time."

Canon to Start Mass Production of Low-Light SPAD Sensor for Security Cameras in 2022, Builds New CIS Fab in 2023
December 7, 2021 By Leave a Comment
Image Sensors World Go to the original article...
Nikkei-Asia: Canon plans to start mass-production of the 3.2MP SPAD sensor for security cameras in 2022. The sensor is said to provide a color night vision, as well as ToF feature:"The sensor can recognize light at one-tenth the brightness conventional sensors need, lending itself to a range of industrial applications such as driving and surveillance.
The number of pixels in a sensor is key to image clarity, and Canon's SPAD sensor boasts 3.2 million, making it the world's densest, more than three times the number of the company's conventional sensor. It can recognize the time of light returning in units of less than a nanosecond, allowing for more accurate object recognition.
Canon's factory in Kawasaki will begin mass-producing the new sensor in the second half of 2022. The company plans to install the sensors in its own security cameras that it is to introduce by the end of next year. It will also market the sensors to other companies.
In 2023, Canon will invest more than 21 billion yen ($185 million) to build a new image sensor plant in the Kanagawa Prefecture city of Hiratsuka, where it plans to gradually increase production of the sensor. The sensor can be made with the production technology used for CMOS sensors and at around the same cost."

MIPI CSE Adds Functional Safety to Automotive Image Sensor Interface
December 5, 2021 By Leave a Comment
Image Sensors World Go to the original article...
MIPI Alliance has recently released the Camera Service Extensions (MIPI CSESM) v1.0 specification, which enhances the MIPI Camera Serial Interface 2 (MIPI CSI-2) image sensor interface with end-to-end functional safety and other features for automotive applications:
- A cyclic redundancy check (CRC-32) to detect data transmission errors, ensuring the image data captured by the sensor is accurate when received at the ECU
- A frame counter to detect frame loss or duplication, with its accuracy verified by the CRC, ensuring the continuity of video streams from cameras to ECU
- A message counter that can be used as a timeout checker to detect any loss of data caused by a stopped or stuck transmission between an image sensor and ECU
- Service Extension Packet (SEP) functionality is implemented over the entire PHY link, which provides packetization and uniform delivery of image data.
While the initial release of CSE provides the functional safety enabling features described above, the next version is already under development. CSE v2.0 will add security features to CSE_i and CSE_c, and will work with the upcoming MIPI Security specification to bring end-to-end security to the MASS framework. Version 2.0 is expected to be completed in mid-2022.

EDoF-ToF Paper
December 2, 2021 By Leave a Comment
Image Sensors World Go to the original article...
Rice University publishes an OSA Optica paper "EDoF-ToF: extended depth of field time-of-flight imaging" by Jasper Tan, Vivek Boominathan, Richard Baraniuk, and Ashok Veeraraghavan."Conventional continuous-wave amplitude-modulated time-of-flight (CWAM ToF) cameras suffer from a fundamental trade-off between light throughput and depth of field (DoF): a larger lens aperture allows more light collection but suffers from significantly lower DoF. However, both high light throughput, which increases signal-to-noise ratio, and a wide DoF, which enlarges the system’s applicable depth range, are valuable for CWAM ToF applications. In this work, we propose EDoF-ToF, an algorithmic method to extend the DoF of large-aperture CWAM ToF cameras by using a neural network to deblur objects outside of the lens’s narrow focal region and thus produce an all-in-focus measurement. A key component of our work is the proposed large-aperture ToF training data simulator, which models the depth-dependent blurs and partial occlusions caused by such apertures. Contrary to conventional image deblurring where the blur model is typically linear, ToF depth maps are nonlinear functions of scene intensities, resulting in a nonlinear blur model that we also derive for our simulator. Unlike extended DoF for conventional photography where depth information needs to be encoded (or made depth-invariant) using additional hardware (phase masks, focal sweeping, etc.), ToF sensor measurements naturally encode depth information, allowing a completely software solution to extended DoF. We experimentally demonstrate EDoF-ToF increasing the DoF of a conventional ToF system by 3.6 ×, effectively achieving the DoF of a smaller lens aperture that allows 22.1 × less light. Ultimately, EDoF-ToF enables CWAM ToF cameras to enjoy the benefits of both high light throughput and a wide DoF."

Nature paper "Silicon: quantum dot photovoltage triodes" by Wen Zhou, Li Zheng, Zhijun Ning, Xinhong Cheng, Fang Wang, Kaimin Xu, Rui Xu, Zhongyu Liu, Man Luo, Weida Hu, Huijun Guo, Wenjia Zhou & Yuehui Yu from Chinese Academy of Sciences and ShanghaiTech University presents a concept of 1550nm photodetector with internal gain:"Silicon is widespread in modern electronics, but its electronic bandgap prevents the detection of infrared radiation at wavelengths above 1,100 nanometers, which limits its applications in multiple fields such as night vision, health monitoring and space navigation systems. It is therefore of interest to integrate silicon with infrared-sensitive materials to broaden its detection wavelength. Here we demonstrate a photovoltage triode that can use silicon as the emitter but is also sensitive to infrared spectra owing to the heterointegrated quantum dot light absorber. The photovoltage generated at the quantum dot base region, attracting holes from silicon, leads to high responsivity (exceeding 410 A·W−1 with Vbias of −1.5 V), and a widely self-tunable spectral response. Our device has the maximal specific detectivity (4.73 × 1013 Jones with Vbias of −0.4 V) at 1,550 nm among the infrared sensitized silicon detectors, which opens a new path towards infrared and visible imaging in one chip with silicon technology compatibility."
