ACTIVITY MAP CREATING DEVICE, ACTIVITY MAP CREATING SYSTEM, AND ACTIVITY MAP CREATING METHOD

An activity map creating device creates an activity situation of a moving object, and outputs an activity map visualizing the activity situation of the moving object. The device includes a moving object detector that detects the moving object from a captured image, and a first activity value obtainer that obtains a moving object activity value for each of a plurality of detection elements. The device further includes a target area setter that sets a target area, a second activity value obtainer that aggregates, in the target area, moving object activity values of the respective detection elements, and a map generator that creates the activity map for the target area based on the aggregation. The device further includes an output information generator that creates output information on the activity map.
