Abstract

Proper display is performed in consideration of a characteristic that a vehicle head-up display device 1 is mounted in a vehicle. The vehicle head-up display device 1 for displaying a virtual image displays plural virtual images which are different in focal distance.

Claims

1. A vehicle head-up display device for displaying a virtual image, characterized in that a plurality of virtual images which are different in focal distance are displayed.

2. The vehicle head-up display device according to claim 1, wherein light is projected to a projection face formed on a front windshield or a projection face formed on a member that is provided so as to correspond to the front windshield, thereby displaying a virtual image in a front windshield corresponding area as an area corresponding to the front windshield, and a plurality of virtual image display areas where virtual images to be displayed are different in focal distance are formed in the front windshield corresponding area.

3. The vehicle head-up display device according to claim 2, wherein with respect to the plurality of virtual display areas formed in the front windshield corresponding area, a focal distance of a virtual image to be displayed in the virtual image display area located at an upper side is set to be longer than a focal distance of a virtual image to be displayed in the virtual image display area located at a lower side.

4. The vehicle head-up display device according to claim 3, wherein at least an upper virtual image display area formed in an area corresponding to an upper area of the front windshield, and a lower virtual image display area formed in an area corresponding to a lower area of the front windshield are formed in the front windshield corresponding area.

5. The vehicle head-up display device according to claim 4, wherein a virtual image associated with information relating to driving is displayed in the lower virtual image display area, and a virtual image associated with information containing information other than the information relating to the driving is displayed in the upper virtual image display area.

6. The vehicle head-up display device according to claim 5, further comprising traveling state detecting means for detecting a traveling state, wherein a virtual image is displayed in the upper virtual image display area when it is detected by the traveling state detecting means that the vehicle is under stopping.

7. The vehicle head-up display device according to claim 2, wherein with respect to the plurality of virtual display areas formed in the front windshield corresponding area, virtual images to be displayed in respective areas which are away from one another in a right-and-left direction are different in focal distance.

8. The vehicle head-up display device according to claim 2, wherein with respect to the plurality of virtual image display areas formed in the front windshield corresponding area, a projecting unit for projecting light is provided for each of the areas.
