A Wide Linear Dynamic Range Image Sensor Based on Asynchronous Self-Reset and Tagging of Saturation Events
(Institute of Electrical and Electronics Engineers, 2017)
We report a high dynamic range (HDR) image sensor with a linear response that overcomes some of the limitations of sensors with pixels with self-reset operation. It operates similar to an active pixel sensor, but its pixels ...

Asynchronous spiking pixel with programmable sensitivity to illumination
(Institute of Electrical and Electronics Engineers, 2018)
A spiking pixel to be used in image sensor arrays for asynchronous frame-based operation is presented. The pixel features both local and global adaptive sensitivity to the illumination level. Local adaptation is performed ...

Sun Sensor Based on a Luminance Spiking Pixel Array
(Institute of Electrical and Electronics Engineers, 2017)
We present a novel sun sensor concept. It is the very first sun sensor built with an address event representation spiking pixel matrix. Its pixels spike with a frequency proportional to illumination. It offers remarkable ...

Feedforward Categorization on AER Motion Events Using Cortex-Like Features in a Spiking Neural Network
(Institute of Electrical and Electronics Engineers, 2015)
This paper introduces an event-driven feedforward categorization system, which takes data from a temporal contrast address event representation (AER) sensor. The proposed system extracts bio-inspired cortex-like features ...
