Live Demonstration: Event-driven high-speed imaging

This live demonstration shows a biology-inspired highly efficient approach to high-speed video data acquisition based on the ATIS image sensor technology. Gray-level image information is acquired pixel-individually and event-driven at a temporal resolution equivalent to thousands of frames-per-second while the data rate is kept at a fraction of the rate encountered with conventional high-speed cameras by means of near ideal pixel-level redundancy suppression. The presented ATIS camera combines three consecutive exposure estimation / measurement steps that apply different trade-offs between measurement speed, accuracy and noise. Early estimates of pixel values deliver between 10 and 100 times faster updates than the eventual full-swing integrating exposure measurement that reaches 1 kFPS equivalent temporal resolution at sunny outdoor conditions. In addition, a miniaturized ATIS camera is demonstrated that constitutes one of the first (if not the first) neuromorphic device designed specifically for application in a commercial medical product.
