Abstract

An image generating device and method for a vehicle that improves the image quality of the output image and provides images that can be better perceived by the driver. A camera allows adjustment of the image output range by manipulation from external to the camera, an image processing device performs manipulation of the camera and image processing of the image acquired by the camera and an image display device displays the image processed by the image processing device. The image output range of the camera can be adjusted corresponding to a signal from image processing device.

Claims

1. An image generating device for a vehicle, comprising:

an image pickup device operable to capture images around the vehicle and to allow adjustment of an image output range to output the captured images;

an image processing device operable to receive and to process portions of the captured images corresponding to the image output range; and

a display device operable to display an image processed by the image processing device.

2. The image generating device according to claim 1, wherein the image output range comprises at least two ranges and wherein the image pickup device is further operable to output the captured images in accordance with one of the at least two ranges.

3. The image generating device according to claim 2 wherein the image pickup device is switchable between a partial image mode and a full image mode.

4. The image generating device according to claim 1 wherein the image pickup device is further operable to adjust the image output range based on a signal external from the image pickup device.

5. The image generating device according to claim 1 wherein the image processing device is further operable to define the image output range using coordinates of four or more points.

6. The image generating device according to claim 1 wherein the image processing device is further operable to define the image output range with a rectangular shape.

7. The image generating device according to claim 1 wherein the image processing device is further operable to normalize the captured images to a rectangular shape, the rectangular shape being the image for display on the display device.

8. The image generating device according to claim 1 wherein the image processed by the image processing device is a rectangular shape comprising a combination of a plurality of cut-out images from at least some of the captured images.

9. The image generating device according to claim 1 wherein said image pickup device is composed of wide-angle cameras for capturing front views, left-side views, right-side views, and rear views of the vehicle;

and wherein the image processed by the image processing device is at least one of a bird'"'"'s-eye view, a front side view, a front lower view, a rear side view and a rear view.

10. An image generating device for a vehicle, comprising:

image pickup means for capturing images surrounding the vehicle and outputting the images with an adjustable image output range;

image processing means for receiving the output images and for image processing of the output images corresponding to the output range; and

display means for displaying the processed images.

11. An image generating method for a vehicle, comprising:

capturing images surrounding the vehicle;

outputting each of the captured images with an adjustable image output range;

processing the output images corresponding to the image output range; and

displaying at least one processed image.

12. The image generating method according to claim 11, further comprising:

defining at least two image output ranges; and

using one of the at least two image output ranges for outputting each of the captured images.

13. The image generating method according to claim 12, further comprising:

defining part of the captured images as the image output range for outputting each of the captured images.

14. The image generating method according to claim 11, further comprising:

adjusting the image output range corresponding to a signal from external to at least one camera capturing the images.

15. The image generating method according to claim 11 wherein outputting each of the captured images with the adjustable image output range further comprises outputting each of the captured images with a rectangular shape.

16. The image generating method according to claim 11, further comprising:

normalizing each of the output images to a rectangular shape by image processing corresponding to the image output range.

17. The image generating method according to claim 16, further comprising:

combining each of the rectangular shapes into a single image; and

wherein displaying the at least one processed image includes displaying the single image.

18. The image generating method according to claim 11 wherein processing the output images corresponding to the image output range further comprises combining a plurality of cut-out images from at least some of the captured images in a single rectangular image;

and wherein displaying the at least one processed image includes displaying the single rectangular image.

19. The image generating method according to claim 11 wherein capturing images surrounding the vehicle comprises operating a plurality of wide-angle cameras to capture a front view, a left-side view, a right-side view, and a rear view of the vehicle;

and wherein displaying the at least one processed image includes displaying at least one of a bird'"'"'s-eye view, a front side view, a front lower view, a rear side view and a rear view.

20. The image generating method according to claim 11 wherein the adjustable image output comprises at least two ranges, the at least two ranges including a partial image range and a full image range.
