In the past few years, fusing NIR and color images has been explored in general computational photography and computer vision tasks, where traditionally only color images are used. The additional information provided by the differences of light and scene r ...
Event-based dynamic vision sensors (DVSs) asynchronously report log intensity changes. Their high dynamic range, sub-ms latency and sparse output make them useful in applications such as robotics and real-time tracking. However they discard absolute intens ...
Single-photon avalanche diode (SPAD) imagers typically have a relatively low fil factor, i.e. a low proportion of the pixel's surface is light sensitive, due to in-pixel circuitry. We present a microlens array fabricated on a 128x128 single-photon avalanch ...
This letter presents a CMOS-compatible photodetector displaying direct light-to-time conversion and intrinsic charge integration with a very low dark current. This device is particularly adapted for applications requiring high sensitivity such as biolumine ...

An area- and power-optimized asynchronous 32x interleaved SAR ADC achieving 36 GS/s at 110mW and 1V supply on the interleaver and 0.9V on the SAR ADCs is presented. The ADC features a 2-channel interleaver with data demultiplexing for enhanced bandwidth, a ...
An edge-detection scheme suitable for machine vision and digital motion detection applications is presented. The scheme is inspired by the human visual system (human retina) and modified for a compact and scalable CMOS hardware implementation. In addition, ...
This demonstration will show the features of the Dynamic and Active-Pixel Vision Sensor (DAVIS) reported at the VLSI Symposium and the International Imager Sensor Workshop in 2013. This sensor concurrently outputs conventional CMOS image sensor frames and ...
Since the first introduction of digital cameras, the camera market has been taking tremendous interest from many fields. This trend has even accelerated when the cost, size, and power consumption of such devices were reduced with the introduction of camera ...
