Dynamic Vision Sensor (DVS)

In 2015, Prof. Tobi Delbruck, of the Department of Neuroinformatics, developed the Dynamic Division Sensor (DVS) technology, which is now owned by inivation. Instead of providing an image sequence with a constant frequency, the visual sensors only send the DVS information about the pixels in which there have been significant changes to the brightness (=events). Events are marked with a timestamp that is precise to the microsecond and then immediately transmitted asynchronously. Because only non-redundant information is transmitted these event cameras are energy-efficient and capable of recording very fast movements. The dynamic range (> 120 dB) is more than twice as high as other cameras.
