First Claim
Patent Images
1. A vehicle display apparatus comprising:
- a camera to take an image information of a forward direction of a vehicle;
a display device to display the image information to a display area; and
a processing device,wherein said processing device has the processing steps of;
extracting a current focus of expansion (FOE) from the image information for use by a display control;
matching both ordinates of between the current FOE and a standard FOE to determine a distance for moving the display area, said standard FOE being fixed preliminarily at a predetermined portion of the display area;
moving the display area; and
displaying the image information to the display area.

Abstract
The present invention is to provide a vehicle display apparatus having a clear view. When a vehicle runs on a flat road, a standard FOE (focus of expansion) is set so as that a horizon line is positioned at a central portion of a display area. When the vehicle approaches to an uphill road, the display area is moved to match ordinates of between a current FOE and the standard FOE. When the vehicle approaches to a downhill road, the display area is moved to match the ordinates of between the current FOE and standard FOE.

2. A vehicle display apparatus, comprising
a camera to take an image information of a forward direction of a vehicle; -
a display device to display the image information to a display area; and a processing device, wherein said processing device has the processing steps of; extracting a current focus of expansion (FOE) from the image information for use by a display control; marching both ordinates of between the current FOE and a standard FOE, said standard FOE being fixed preliminarily at a predetermined portion of the display area; and displaying the image information to the display area; wherein said processing step of extracting the current FOE has the steps of; extracting white lines of both sides of a road from the image information; calculating two straight lines corresponding to the white lines; calculating the current FOE from a intersection of the two straight lines; matching both ordinates of between the current FOE and the standard FOE; and displaying the image information to the display area. - View Dependent Claims (3)

4. A vehicle display apparatus comprising:
-
a camera to take an image information of a forward direction of a vehicle; a display device to display the image information to a display area; a near-infrared camera to take reflection spectra of the forward direction of the vehicle; and a processing device, wherein said processing device has the processing steps of; extracting a current horizon line from the reflection spectra for a display control; matching both ordinates of between the current horizon line and a standard horizon line, said standard horizon line being preliminarily fixed at a predetermined portion of the display area; and displaying the image information to the display area. - View Dependent Claims (5, 6)

7. A vehicle display apparatus comprising:
-
a camera to take an image information in a camera field of a forward direction of a vehicle; a display device to display the image information to a display area; a Global Positioning System (GPS) to determine a position and a moving direction of the vehicle; a tilt sensor to determine a tilt angle between the moving direction and a level line; and a processing device, wherein said processing device has the processing steps of; extracting map data corresponding to each position of the vehicle from a memory device; determining a highest visible position in the camera field at a current position of the vehicle from altitudes corresponding to the tilt angle in the map data; determining a highest visible position angle of between the highest visible position and a standard plane; matching both ordinates of between the highest visible position in the image information and a camera level line by an angle difference between the highest visible position angle and the tilt angle; and displaying the image information to the display area.
