Abstract
A custom CMOS imager with integrated motion computation is described. The architecture is centered around a compact mixed-mode pixel with digital asynchronous self-signaling capabilities. An address-event communication channel with an external time-stamp protocol is used to compute image features velocities. The motion sensor could be used in applications such as self-guided vehicles, mobile robotics and smart surveillance systems.
