A device and a method for predicting a collision area of a high speed small object are provided. The method includes following steps: obtaining, by a processor, a sparse event stream data through an event camera; obtaining, by the processor, an event stream data corresponding to a cumulative time interval using the sparse event stream data; predicting, by the processor, a collision area category using a temporal spatial feature expression associated with the event stream data, wherein the collision area category corresponds to a high speed small object; and outputting, by the processor, the collision area category.
