Display apparatus for a vehicle
First Claim
1. A display apparatus for a vehicle, wherein projecting a picture displayed on an image source onto a member of projection in front of a vehicle driver for superimposing a virtual image of said picture on a front view looked through a windshield from an eye point within the vehicle, comprising:
- a storage device for storing a distance information of superimposed viewing, the distance information of superimposed viewing indicating a distance between an obstacle existing in the view ahead the vehicle and the vehicle whereby the virtual image and the obstacle are viewed as a superimposed front view from the eye point;
distance measuring means for measuring a distance between the vehicle and the obstacle;
judging means for judging whether or not the virtual image is superimposed on the obstacle based on the distance measured by the distance measuring means and the distance information of superimposed viewing stored in the storage device; and
control means for controlling to stop the projection of the picture when the judging means judges that the virtual image is superimposed on the obstacle.
