Abstract

A driving support unit captures an image of a driver'"'"'s blind spot due to presence of a pillar of a vehicle includes at least first and second cameras which are mounted on the vehicle, a display device for displaying the image on the interior surface of the pillar and a control section for detecting position of the head of the driver, calculating a blind spot angle due to the presence of the pillar in accordance with the position of the head of the driver, and for selecting, based on the calculated angle, one of the cameras to capture the image. The first camera captures an image the major portion of which is an area to the side of the vehicle, and the second camera captures an image the major portion of which is an area to the front of the vehicle.

Claims

1. A driving support apparatus for capturing an image of an area, which is hidden as a blind spot of a driver of a vehicle due to presence of a pillar of the vehicle, and for displaying a captured image on an interior side of the pillar, comprising:

plural imaging devices mounted at different positions on the vehicle to capture images of different blind spot areas created by the presence of the pillar and position of the driver;

detecting means for detecting position of the driver seated in a driver'"'"'s seat in the vehicle;

angle calculating means for calculating an angle of the blind spot due to the presence of the pillar on the basis of the detected position of the driver;

selecting means for selecting one of the imaging devices, in accordance with the calculated angle of the blind spot, from among the plural imaging means;

image signal obtaining means for receiving an image signal from the selected imaging device; and

output control means for displaying an image of the blind spot area on the interior side of the pillar in the vehicle, on the basis of the image signal which is received from the selected imaging device.

2. The driving support apparatus according to claim 1, wherein:

the detecting means detects coordinates of the head of the driver.

3. The driving support apparatus according to claim 1, further comprising:

image processing means for image processing of the image signal received from the selected imaging means, in accordance with the detected position of the driver.

4. The driving support apparatus according to claim 1 wherein the two imaging devices are mounted at different positions on the pillar.

5. The driving support apparatus according to claim 1 wherein the two imaging devices are mounted at opposing upper and lower ends of the pillar.

6. The driving support apparatus according to claim 1 wherein the blind spot image displayed on the interior side of the pillar is in register with the actual view of the driver through the front window and front door window so that the displayed image merges with the driver'"'"'s actual view.

7. The driving support apparatus according to claim 1 wherein the output control means includes a projector focused on the pillar.

8. A driving support method for capturing and displaying an image of an area, which is hidden as a blind spot of a driver of a vehicle due to presence of a pillar of the vehicle, comprising:

imaging the blind spot using plural imaging devices mounted at different positions on the vehicle to capture images of different blind spot areas created by the presence of the pillar and position of the driver;

detecting position of the driver seated in a driver'"'"'s seat in the vehicle;

calculating an angle of the blind spot due to the presence of the pillar on the basis of the detected position of the driver;

selecting one of the imaging devices, in accordance with the calculated angle of the blind spot, from among the plural imaging devices;

receiving an image signal from the selected imaging device; and

displaying an image of the blind spot area on the interior side of the pillar in the vehicle, on the basis of the image signal which is received from the selected imaging device.

9. The driving support method according to claim 8, wherein:

coordinates of the head of the driver are detected as the position of the driver.

10. The driving support method according to claim 8, further comprising:

image processing the image signal received from the selected imaging device in accordance with the detected position of the driver.

11. A driving support apparatus for capturing an image of an area, which is hidden as a blind spot of a driver of a vehicle due to presence of a pillar of the vehicle, and for displaying a captured image on an interior side of the pillar, comprising:

plural imaging devices mounted at different positions on the vehicle to capture images of different blind spot areas created by the presence of the pillar and position of the driver, the plural imaging devices including a first imaging device which captures a first image and a second imaging device which captures a second image, at least a major portion of the first image including an area to a front side of the vehicle and at least a major portion of the second image including an area in front of the vehicle;

detecting means for detecting position of the driver seated in a driver'"'"'s seat in the vehicle;

angle calculating means for calculating a maximum horizontal blind spot angle of the blind spot due to the presence of the pillar on the basis of the detected position of the driver;

selecting means for selecting one of the imaging means, in accordance with the calculated maximum horizontal blind spot angle, from among the plural imaging means, wherein the selecting means, responsive to a determination that a maximum horizontal blind spot angle due to the presence of the pillar is less than predetermined angle, selects the first imaging device to capture an image, and, responsive to a determination that the maximum horizontal blind spot angle is equal to or greater than the predetermined angle, selects the second imaging device to capture an image;

image signal obtaining means for receiving an image signal from the selected imaging means; and

output control means for displaying an image of the blind spot on the interior side of the pillar in the vehicle, on the basis of the image signal which is received from the imaging means.

12. A driving support method for capturing and displaying an image of an area, which is hidden as a blind spot of a driver of a vehicle due to presence of a pillar of the vehicle, comprising:

imaging the blind spot using plural imaging devices mounted at different positions on the vehicle to capture images of different blind spot areas created by the presence of the pillar and position of the driver, the plural imaging devices include a first imaging device for capturing an image at least a major portion of which includes an area to a front side of the vehicle and a second imaging device for capturing an image at least a major portion of which includes an area in front of the vehicle;

detecting position of the driver seated in a driver'"'"'s seat in the vehicle;

calculating a maximum blind spot angle for the blind spot due to the presence of the pillar on the basis of the detected position of the driver;

responsive to a determination that a calculated maximum horizontal blind spot angle due to the presence of the pillar is less than predetermined angle, selecting the first imaging device to capture an image, and, responsive to a determination that the calculated maximum horizontal blind spot angle is equal to or greater than the predetermined angle, selecting the second imaging device to capture an image;

receiving an image signal from the selected imaging device; and

displaying an image of the blind spot area, captured by the selected imaging device, on the interior side of the pillar in the vehicle, on the basis of the image signal which is received from the selected imaging device.
