Abstract :
Summary form only given. We demonstrate the very first tri-color asynchronous pixel-event vision sensor, the latest addition of the growing family of bio-inspired AER (Address Event Representation) vision sensors. It is an asynchronous pulse/frequency density modulation (PDM/PFM) sensor (popularly known as octopus retina) that employs stacked photo diodes for color separation. Simple linear combination of the sensor´s inherent pseudo color representation is employed to reconstruct approximate a RGB video stream. The 22×22 pixel array has been fabricated in the standard STM 90nm CMOS process.
