Abstract

A vehicle periphery display control system displays peripheral images of a vehicle which are captured by a plurality of cameras mounted on the vehicle in respective different positions thereon. A storage medium stores road configuration information of a road. A positioning unit identifies the present position of the vehicle on the road. A image switching decision unit selects either one of images captured by the cameras based on specific road configuration information of a peripheral area around the vehicle, which includes the present position identified by the present position identifying unit, of the road configuration information stored in the storage medium. The image switching decision unit controls a display unit to display the image selected by the selecting unit.

Claims

1. A vehicle periphery display control system which displays peripheral images of a vehicle which are captured by a plurality of cameras mounted on the vehicle in respective different positions thereon, comprising:

a storage medium configured to store road configuration information;

a present position identifying unit configured to identify the present position of the vehicle;

a selecting unit configured to select at least one of images captured by the cameras based on specific road configuration information of a peripheral area around the vehicle, which includes the present position identified by said present position identifying unit, said specific road configuration information being retrieved from the road configuration information stored in said storage medium;

a display unit configured to display the image selected by said selecting unit; and

an input unit configured to enter a user'"'"'s action and output a signal responsive to the user'"'"'s action;

wherein

the selecting unit is configured to communicate with the plurality of cameras each configured with a fish-eye lens, the cameras being disposed to jointly capture images of all front, rear, left, and right peripheral areas of the vehicle,

the selecting unit is configured to display a display format of the selected image based on the signal from the input unit, and use selective items for the display format including whether or not the selected image is to be corrected out of a distortion by the fish-eye lens, a position of a viewpoint in the selected image, and whether the vehicle is to be displayed hypothetically in the selected image,

the display unit is configured to display the selected image based on the display format selected by the selecting unit, and

the display unit includes a plurality of monitors and is configured to display the selected image on at least one of the monitors disposed at a position corresponding to a position where the selected image is captured.

2. A vehicle periphery display control system according to claim 1, wherein said selecting unit is configured to identify the number of lanes of a road on which the vehicle is traveling based on said present position and said specific road configuration information of the peripheral area around the vehicle, and to select at least one of the images captured by the cameras based on the identified number of lanes, to be displayed by said display unit.

3. A vehicle periphery display control system according to claim 1, wherein said selecting unit is configured to identify a lane of a road in which the vehicle is traveling based on said present position and said specific road configuration information of the peripheral area around the vehicle, and to select at least one of the images captured by the cameras based on the identified lane and said specific road configuration information, to be displayed by said display unit.

4. A vehicle periphery display control system according to claim 1, wherein said selecting unit is configured to select at least one of the images captured by the cameras based on a planned route along which said vehicle is to travel.

5. A vehicle periphery display control system according to claim 1, wherein the images captured by the cameras include an image captured by a front camera mounted on a front end of the vehicle and having a field of view including lateral areas of the vehicle, and said selecting unit selects the image captured by the front camera to be displayed by said display unit when the vehicle enters an intersection.

6. A vehicle periphery display control system according to claim 1, wherein said display unit produces a warning sound each time the image displayed by said display unit changes to another image.

12. A vehicle periphery display control system according to claim 1,

further comprising the plurality of cameras, each configured with the fish-eye lens, mounted on the vehicle,

wherein the cameras each configured with the fish-eye lens are disposed to capture images such that the collective images from the cameras continuously cover a 360 degree field of view around the vehicle,

the selecting unit being configured to select from the images continuously covering the 360 degree field for display.

13. A vehicle periphery display control system according to claim 1, wherein

when the selected image is to be corrected out of distortion by the fish-eye lens, a viewpoint of the selected image is changed to a position behind the vehicle and the vehicle is displayed hypothetically in the image, and

when the selected image is not corrected out of distortion by the fish-eye lens, the viewpoint is not changed.

7. A system which controls the display of peripheral images of a vehicle which are captured respectively by a plurality of cameras mounted in respective different positions on the vehicle, comprising:

a positioning unit configured to identify the present position of the vehicle on a road;

a storage unit configured to store road configuration information;

a display unit configured to selectively display the peripheral images captured by the cameras for being observed by a driver of the vehicle;

an input unit configured to enter a user'"'"'s action; and

an image switching controller configured to control said display unit for displaying at least one of the peripheral images captured by the cameras based on the road configuration information of the road around the vehicle which includes the present position identified by said positioning unit;

wherein

the image switching control is configured to communicate with the plurality of cameras each configured with a fish-eye lens, the cameras being disposed to jointly capture images of all front, rear, left, and right peripheral areas of the vehicle,

the image switching controller is configured to select a display format of the captured image based on a signal from the input unit, and use selective items for the display format including whether or not the captured image is to be corrected out of a distortion by the fish-eye lens, a position of a viewpoint in the captured image, and whether the vehicle is to be displayed hypothetically in the captured image,

the display unit is configured to display the captured image based on the display format selected by the image switching controller, and

the display unit includes a plurality of monitors and is configured to display the captured image on at least one of the monitors disposed at a position corresponding to a position where the captured image is captured.

8. A system according to claim 7, wherein said road configuration information includes the number of lanes of the road and the lane in which the vehicle is currently traveling.

9. A system according to claim 8, wherein said road configuration information further includes a merging road joined to said road.

10. A system according to claim 8, wherein said road configuration information further includes a turn to be made by the vehicle.

11. A system according to claim 8, wherein said road configuration information further includes a planned route along which the vehicle is to travel.

14. A system according to claim 7,

further comprising the plurality of cameras, each configured with the fish-eye lens, mounted on the vehicle,

wherein the cameras each configured with the fish-eye lens are disposed to capture images such that the collective images from the cameras continuously cover a 360 degree field of view around the vehicle,

the selecting unit being configured to select from the images continuously covering the 360 degree field for display.

15. A system according to claim 7, wherein

when the selected image is to be corrected out of distortion by the fish-eye lens, a viewpoint of the selected image is changed to a position behind the vehicle and the vehicle is displayed hypothetically in the image, and

when the selected image is not corrected out of distortion by the fish-eye lens, the viewpoint is not changed.
