Abstract
In a display control device, a direction of a light source in a region around a self-vehicle is estimated, and whether the direction of the light source coincides with a display arrangement direction which indicates an arrangement direction of a display portion as viewed from a passenger in the self-vehicle is determined. Then, a brightness of the display portion is set to be increased when the direction of the light source coincides with the display arrangement direction, compared with when the direction of the light source does not coincide with the display arrangement direction. Therefore, the brightness of the display portion can be more accurately controlled such that the display portion is easily viewed by the passenger in the self-vehicle.
Claims7
A display control device configured to display an image on a display portion mounted to a vehicle, the display control device comprising:
- a light-source direction estimating means for estimating a direction of a light source in a region around the vehicle;
- a direction-coincidence determining means for determining whether the direction of the light source coincides with a display arrangement direction, which indicates an arrangement direction of the display portion as viewed from a passenger in the vehicle;
- and
- a first brightness setting means for setting a brightness of the display portion to be increased when the direction of the light source coincides with the display arrangement direction, compared with when the direction of the light source does not coincide with the display arrangement direction.
A display control method for displaying an image on a display portion mounted to a vehicle, the method comprising:
- estimating a direction of a light source in a region around the vehicle;
- determining whether the direction of the light source coincides with a display arrangement direction, which indicates an arrangement direction of the display portion as viewed from a passenger in the vehicle;
- and
- setting a brightness of the display portion to be increased when the direction of the light source coincides with the display arrangement direction, compared with when the direction of the light source does not coincide with the display arrangement direction.
