Abstract
A method for preventing glare caused by a head lamp of an opposite side vehicle is provided. The method includes detecting a position of the head lamp from an image photographed in a front direction of a vehicle, when a light is detected in front of the vehicle. The detected position of the head lamp is then matched on a head-up display image and a filtering image is generated to block the light of the head lamp using the head-up display image. The filtering image is finally output on a vehicle windshield.
