An event analysis system capable of appropriately estimating a specific event is provided. Provided are an estimation unit that estimates a track of a person based on video data acquired by a camera, a determination unit that determines, based on determination information for determining a specific event, whether or not the track estimated by the estimation unit corresponds to the specific event, a filter unit that removes, based on normal event information for identifying a normal event, the normal event from the events that have been determined by the determination unit to correspond to the specific event, and an output unit that outputs information indicating that the event is occurring after the normal event has been removed by the filter unit.
