1. A trajectory analysis device comprising:
a display interface configured to display relevant information on a trajectory of a moving object, the relevant information including at least one of a moving image associated with the trajectory of the moving object or a list including candidates each indicating the moving image;
a storage configured to stores trajectory data indicating a plurality of trajectories and the relevant information;
an input interface configured to receive input by a user operation; and
a controller configured to control the display interface based on the relevant information stored in the storage and the user operation input on the input interface,
wherein the controller is configured to:
cause the display interface to display a plurality of staying areas based on the trajectory data, the plurality of staying areas each being an area in which one or more trajectories included in the plurality of trajectories stays;
receive a first user operation selecting one staying area from among the plurality of staying areas, the first user operation being received via the input interface;
extract a set of trajectories from the plurality of trajectories based on the selected one staying area, the set of trajectories being trajectories that stay in the selected one staying area, from among the plurality of trajectories;
cause the display interface to display the set of trajectories that stay in the selected one staying area;
receive a second user operation designating a passing area through which at least one of the set of trajectories passes, the designated passing area being different from the selected one staying area, the second user operation being received via the input interface;
extract at least one trajectory from the set of trajectories based on the designated passing area, the at least one trajectory being a trajectory that passes through the designated passing area, from among the set of trajectories;
extract the relevant information corresponding to the at least one trajectory; and
cause the display interface to display the at least one trajectory and the extracted relevant information.
