1. A position detection system comprising:
an event-driven vision sensor that includes a sensor array including sensors each generating an event signal when a change in intensity of incident light is detected;
a microlens array that includes at least first and second microlenses for guiding the light to first and second regions of the sensor array, respectively; and
a terminal device that has a reception unit for receiving the event signal from the vision sensor, and a position detection unit for detecting a three-dimensional position of the change in the intensity of light, from the event signal generated by each sensor in the first region and the second region;
wherein as to each sensor of the sensor array, sensor identification information of a respective event output signal for the sensor is associated in advance with a respective one of the regions on the sensor array so as to specify a respective one of the microlenses to which the event output signal corresponds.
