Patent Images
1. An on-vehicle image pickup apparatus comprising:
- a plurality of cameras disposed at a plurality of positions on a vehicle;
an image processing section that processes images taken by the plurality of cameras; and
a display device that displays the images processed by the image processing section, whereinthe cameras each have a lens capable of focusing the light of an image in a wide-angle space area and an optical-detector that detects the light focused by the lens;
the image processing section performs a process of combining the images of the surroundings of the vehicle taken by the cameras;
a process of displaying an illustration border line in a vehicle display portion on a screen, wherein the illustration border line extends outwardly beyond at least one portion of an image of the vehicle and the shape of the illustration border line is based on the outer shape of the at least one portion of the image of the vehicle; and
a process of displaying the illustration border line in such a manner that a no-image portion in which an image of an area close to the vehicle could not be captured is included in the area enclosed by the illustration border line; and
the image processing section detects an inclination angle of the vehicle with respect to horizontal and displays a portion of the illustration border line at a side to which the vehicle is tilted at a position outside the outline of the actual vehicle by a first margin area having a first width, and displays a portion of the illustration border line at a side opposite the side to which the vehicle is tilted at a position outside the outline of the actual vehicle by a second margin area having a second width less than the first width.

Abstract
Images taken by a plurality of cameras mounted on a vehicle are combined and an image of the surrounding area is developed, in a plane, around a vehicle display portion. The vehicle display portion shows an illustration border line indicative of the outer shape of the vehicle. The outline of the vehicle indicated by the illustration border line is drawn slightly larger than the outer shape of the actual image of the vehicle. This allows margin areas to be formed between the vehicle and its surroundings, thus reducing the possibility of a collision with an obstacle during driving.

12. A method of an operating on-vehicle image pickup apparatus including a plurality of cameras disposed at a plurality of positions on a vehicle, the method comprising:
-
combining images of the surroundings of the vehicle taken by the cameras; combining an illustration border line with the surrounding-area image, wherein the illustration border line extends outwardly beyond at least one portion of an image of the vehicle and the shape of the illustration border line is based on the outer shape of the at least one portion of the image of the vehicle, and the illustration border line is displayed outside an outline of the actual vehicle; and displaying the resulting image on a display screen, including detecting an inclination angle of the vehicle with respect to the horizontal and displaying a portion of the illustration border line at a side to which the vehicle is tilted at a position outside the outline of the actual vehicle by a first margin area having a first width, and displaying a portion of the illustration border line at a side opposite the side to which the vehicle is tilted at a position outside the outline of the actual vehicle by a second margin area having a second width less than the first width. - View Dependent Claims (13, 14, 15, 16, 17, 18)
