In 2015, Prof. Tobi Delbruck, of the Department of Neuroinformatics, developed the Dynamic Division Sensor (DVS) technology, which is a UZH Spin-Off, that 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.
