On the other hand, the intersection determination unit 131 determines whether the vehicle is going to make a right turn (S104). If the right turn is to be made, the view conversion unit 133 displays the right blind spot area on the screen (S105). Referring to FIG. 5, an example of displaying a dead zone in the right direction is determined, in the case of the vehicle 12 located in the four lanes, to be determined as turning right.

 On the other hand, when the vehicle does not make a left turn or a right turn, the view conversion unit 133 displays the blind spot area of the lane adjacent to the vehicle on the screen (S106). Referring to Fig. 5, an example in which a dead zone is displayed when a vehicle located in the first lane changes into a two-lane lane is described.

Referring to FIG. 6, a method of converting a blind spot view upon getting off according to an embodiment of the present invention will be described.

It is not easy to confirm the vehicle approaching from the side of the passenger seat through the side mirrors on the passenger seat side in the driver's seat by the side mirrors on the passenger seat side. An accident may occur due to an obstacle such as a motorcycle 17, 18, or 19 approaching from the rear side when getting on and off the bus 16 or the like. In the present invention, the rear side area of the passenger seat side .

First, the getting off determining unit 132 determines whether the parking assist system SPAS is completed (S201). When the operation of the parking assist system is completed, (S204).

If the operation of the parking assistance system is not completed, the departure determination unit 132 determines whether the vehicle has stopped on the edge of the road (S202).
