A bioinspired 128x128 pixel dynamic-vision-sensor

This paper presents a 128x128 dynamic vision sensor. Each pixel detects temporal changes in the local illumination. A minimum illumination temporal contrast of 10% can be detected. A compact preamplification stage has been introduced that allows to improve the minimum detectable contrast over previous designs, while at the same time reducing the pixel area by 1/3. The pixel responds to illumination changes in less than 3.6μs. The ability of the sensor to capture very fast moving objects has been verified experimentally. A frame-based sensor capable to achieve this, would require at least 100K frames per second.Unión Europea FP7-ICT-2007-1-216777Ministerio de Educación y Ciencia TEC2006-11730-C03-01 (SAMANTA2)Ministerio de Educación y Ciencia TEC2009-10639- C04-01 (VULCANO)Junta de Andalucía P06- TIC-1417 (Brain System
