The present invention suppresses movement of the line of sight of a user, reports the degree of potential risk, and contributes to the safe operation of a vehicle. A vicinity-monitoring unit (300) detects a specific object (W) in the vicinity of the vehicle. A display unit (200) displays a mark image (V1), which is visible to the user (2) and is disposed continuously or intermittently on a trajectory, in a manner so as to surround the specific object (W) at least partially. A control unit (600) calculates the risk potential (RP) in relation to the specific object (W) and alters, in accordance with the calculated risk potential (RP), the line density of the mark image (V1) disposed on the trajectory. |
