Abstract

A display device for a vehicle which includes: an image-taking unit which takes images of an area ahead of the vehicle at predetermined intervals; a display which displays the images taken by the image-taking unit; and a controller which divides a display area of the display into a plurality of areas including a center area and a right-and-left side area, wherein the controller sets a first interval for the image-taking unit for taking images to be displayed in the right-and-left side area of the display to become longer than a second interval for the image-taking unit for taking images to be displayed in the center area.

Claims

1. A display device for a vehicle, comprising:

an image-taking unit which takes images of an area ahead of the vehicle at predetermined intervals;

a display which displays the images taken by the image-taking unit; and

a controller which divides a display area of the display into a plurality of areas including a center area and a right-and-left side area, wherein

the images taken by the image-taking unit includes at least a first image to be displayed in the right-and-left side area of the display and at least a second image to be displayed in the center area of the display;

the first and second images are displayed simultaneously on the display; and

the controller sets a first interval for the image-taking unit for taking at least the first image to become longer than a second interval for the image-taking unit for taking at least the second image.

2. The display device according to claim 1, further comprising:

a velocity measuring unit which measures a velocity of the vehicle,

wherein the controller controls a width of the center area to be narrower and controls a width of the right-and-left side area to be wider in accordance with an increase of the velocity measured by the velocity measuring unit.

3. The display device according to claim 1,

wherein the image-taking unit includes a first camera which takes images to be displayed in the right-and-left side area and a second camera which takes images to be displayed in the center area, and

wherein the controller sets a shutter speed of the first camera to be faster than a shutter speed of the second camera.

4. The display device according to claim 1,

wherein the controller controls the display so as to display a moving picture taken by the image-taking unit in the center area.

5. The display device according to claim 1, further comprising:

a steering angle sensor which measures a steering angle of the vehicle, wherein

the controller determines one of a direction of image taking of the image-taking unit and areas in the images taken by the image-taking unit to be displayed in the display, in accordance with the steering angle measured by the steering angle sensor.

6. The display device according to claim 2,

wherein the image-taking unit includes a first camera which takes images to be displayed in the right-and-left side area and a second camera which takes images to be displayed in the center area, and

wherein the controller sets a shutter speed of the first camera to be faster than a shutter speed of the second camera.

7. The display device according to claim 2,

wherein the controller controls the display so as to display a moving picture taken by the image-taking unit in the center area.

8. The display device according to claim 2, further comprising:

a steering angle sensor which measures a steering angle of the vehicle, wherein

the controller determines one of a direction of image taking of the image-taking unit and areas in the images taken by the image-taking unit to be displayed in the display, in accordance with the steering angle measured by the steering angle sensor.

9. The display device according to claim 3, further comprising:

a steering angle sensor which measures a steering angle of the vehicle, wherein

the controller determines one of a direction of image taking of the image-taking unit and areas in the images taken by the image-taking unit to be displayed in the display, in accordance with the steering angle measured by the steering angle sensor.

10. The display device according to claim 4, further comprising:

a steering angle sensor which measures a steering angle of the vehicle, wherein

the controller determines one of a direction of image taking of the image-taking unit and areas in the images taken by the image-taking unit to be displayed in the display, in accordance with the steering angle measured by the steering angle sensor.

11. The display device according to claim 6, further comprising:

a steering angle sensor which measures a steering angle of the vehicle, wherein

the controller determines one of a direction of image taking of the image-taking unit and areas in the images taken by the image-taking unit to be displayed in the display, in accordance with the steering angle measured by the steering angle sensor.

12. The display device according to claim 7, further comprising:

a steering angle sensor which measures a steering angle of the vehicle, wherein

the controller determines one of a direction of image taking of the image-taking unit and areas in the images taken by the image-taking unit to be displayed in the display, in accordance with the steering angle measured by the steering angle sensor.
