[0002]

2. Description of the Related Art When a vehicle travels on a narrow road, it is difficult to recognize the tip position of the left tip of the vehicle (in the case of a right-hand drive vehicle), and the tip of the vehicle may be mistaken for an obstacle such as a wall or an electric pole. There were times when I made contact. Therefore, it is known that a rod-shaped mark called a corner pole is provided at the tip of the vehicle to measure the distance to an obstacle.
However, such a corner pole becomes a protrusion at the tip of the vehicle, and there is a fear of contact with a pedestrian. Further, the corner pole can be arbitrarily mounted by the purchaser of the vehicle, but since it is usually mounted at the dealer after the vehicle is shipped from the factory, the corner pole must be mounted at the dealer. It was necessary to process the bumper.

On the other hand, in order to provide a mark at the tip of the vehicle for the same purpose as the above-mentioned corner pole, a display device has been proposed which uses a head-up display device to image and display the tip mark near the tip of the vehicle. And special fair 5
-57937 gazette. However,
Since the virtual image of the tip mark is flat, there is little sense of distance,
It was difficult to instantly grasp the positional relationship between the obstacle and the tip mark. Therefore, it has been proposed to display a virtual image with a depth near the end of the vehicle.
No. 25 discloses this.

By the way, in order for an observer to visually measure the distance to an object (real image), it is necessary to look at the object with both eyes, and when not only the real image but also the virtual image is visually recognized, It is well known that the distance sense of a virtual image cannot be grasped without observing it with both eyes. However, with the above-described display device, the observer cannot determine whether the virtual image is viewed with both eyes or one eye. That is, to explain with reference to the schematic diagram of the optical system shown in FIG. 6, when the area S in which the virtual image 2 can be visually recognized is limited by the size of the lens 1, for example, when the left eye 3 deviates from the area S, the virtual image 2 is displayed. I didn't notice what I was seeing with one eye.
Therefore, there is a problem that it is difficult to grasp the sense of distance of the virtual image 2.

According to the present invention, when the observer visually recognizes the virtual image showing the end portion of the vehicle with only one eye, the viewer is notified that the virtual image is not observed with both eyes, and the virtual image can be visually recognized with both eyes. By urging the viewpoint to move to a position,
