This paper presents a high DR, high temporal resolution, frame-free image/video camera that encodes and processes visual information in asynchronous spikes. The event-driven optical sensor features 9.3-bit grayscale imaging at up to 143dB DR and <;0.25% FPN with hardware-based lossless video compression and time-domain correlated double sampling. The main components of the camera - the asynchronous,...
This live demonstration shows high DR, high temporal resolution, frame-free image/video acquisition based on asynchronous events. The presented camera features 9-bit gray-level imaging at up to 143dB DR and <;0.25% FPN with hardware-based lossless video compression and time-domain correlated double sampling. The main components of the camera - an asynchronous, time-based image sensor (ATIS) and...
The presented asynchronous, time-based CMOS dynamic vision and image sensor is based on a QVGA (304×240) array of fully autonomous pixels containing event-based change detection and PWM imaging circuitry. Exposure measurements are initiated and carried out locally by the individual pixel that has detected a brightness change in its field-of-view. Thus pixels do not rely on external timing signals...
In this paper we propose a fully asynchronous, time- based image sensor, which is characterized by high temporal resolution, low data rate (near complete temporal redundancy suppression), high dynamic range, and low power consumption. Autonomous pixels asynchronously communicate the detection of relative changes in light intensity, and the time from change detection to the threshold crossing of a...
This paper presents an embedded vision system for object tracking applications based on a 128times128 pixel CMOS temporal contrast vision sensor. This imager asynchronously responds to relative illumination intensity changes in the visual scene, exhibiting a usable dynamic range of 120 dB and a latency of under 100 mus. The information is encoded in the form of address-event representation (AER) data...
