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...
This paper presents a frame-free time-domain imaging approach designed to alleviate the non-ideality of finite exposure measurement time (intrinsic to all integrating imagers), limiting the temporal resolution of the ATIS asynchronous time-based image sensor concept. The method uses the time-domain correlated double sampling (TCDS) and change detection circuitry already present in the data-driven...
The biomimetic CMOS dynamic vision and image sensor described in this paper is based on a QVGA (304×240) array of fully autonomous pixels containing event-based change detection and pulse-width-modulation (PWM) imaging circuitry. Exposure measurements are initiated and carried out locally by the individual pixel that has detected a change of brightness in its field-of-view. Pixels do not rely on external...
