INFORMATION OUTPUT DEVICE AND INFORMATION OUTPUT METHOD

An information output device comprises an event detection unit (10) that detects an event that has occurred inside or outside a vehicle, a member identification unit (20) that identifies a person or persons who can perceive the event when the event is detected as first members, and an event storage unit (30) for storing event data related to the detected event in association with the first members. The information output device further comprises a data output unit (50) that automatically outputs the event data stored in the event storage unit (30), and the member identification unit (20) identifies persons who can view the event data output from the data output unit (50) as second members. The information output device further comprises an output control unit (40) that determines whether the second members include persons other than the first members, and that prohibits the data output unit (50) from automatically outputting the event data if it is determined that the second members include persons other than the first members.
