University North Caroline at Chapel Hill presents "A Frameless Imaging Sensor with Asynchronous Pixels: An Architectural Evaluation" by Montek Singh, Pintian Zhang, Andrew Vitkus, Ketan Mayer-Patel, and Leandra Vicci at 2017 IEEE Intl Symposium on Asynchronous Circuits and Systems.

"The goal of this work is to develop a novel CMOS camera sensor that provides frameless capture, and has significantly higher dynamic range, finer color sensitivity, and lower noise as compared to the current state-of-the-art sensors. The strength of the approach lies not in developing new types of photodetectors or amplifiers, but in the manner in which information is extracted from the pixel sensor, transported to the processing logic, and processed to yield intensity values. At the heart of the sensor is an asynchronous network to transport events from the pixel sensors to the off-grid processing circuitry. The asynchronous nature of pixel communication is the key to achieving frameless image capture."


The UNC Chapel Hill research group is looking for industrial partners who might be interested in the IP and in partnering with the group for further development.
