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 ...

A sun sensor implemented with an asynchronous luminance vision sensor
(Institute of Electrical and Electronics Engineers, 2017)
A sun sensor implemented with a spiking pixel matrix is reported. It is the very first one based on an asynchronous event-based pixel array. A paradigm associated to classic digital sun sensors is solved with this approach. ...

A high dynamic range image sensor with linear response based on asynchronous event detection
(Institute of Electrical and Electronics Engineers, 2015)
This paper investigates the potential of an image sensor that combines event-based asynchronous outputs with conventional integration of photocurrents. Pixels voltages can be read out following a traditional approach with ...

Pipeline AER arbitration with event aging
(Institute of Electrical and Electronics Engineers, 2017)
We present a simple circuit to handle communication between cells of neuromorphic arrays. It allows cells to operate continuously without waiting for acknowledgement signals back from the AER (Address Event Representation) ...
