  • Publication number: 20210118411
    Abstract: Inventive concepts are configured to protect a passenger by processing an area in a windshield, which matches to a position of a spot on a road, wherein the spot is defined as desirable to not be seen by the passenger when a vehicle is travelling. To this end, the area in the windshield, which matches to a spot on an actual road defined in advance as desirable to not be seen by the passenger, is processed as an invisible area for passenger protection so that the passenger is prevented from visually recognizing the spot. However, when road information required for driving of the vehicle is occluded due to the invisible area which is processed or displayed on the windshield, safe driving is significantly disrupted so that actual road information is overlaid on the invisible area.
