Abstract

A display system for a vehicle is provided with a sensor sensing a traveling condition of a vehicle, an image pick-up device executing an image pick-up to take an image of an outside of the vehicle, a display displaying the image taken by the image pick-up device, an image irregularity determination section determining whether there is an image irregularity or not in the image taken by the image pick-up device based on the traveling condition of the vehicle sensed by the sensor, and a display control section executing a display control processing with respect to one of the image still containing the image irregularity and the image previously picked up and not containing the image irregularity when the image irregularity determination section determines that there is the image irregularity in the image.

Claims

1. A display system for a vehicle, comprising:

a sensor sensing a traveling condition of a vehicle;

an image pick-up device executing an image pick-up to take an image of an outside of the vehicle;

a display displaying the image taken by the image pick-up device;

a memory storing a first image taken by the image pick-up device at a first time and a second image taken by the image pick-up device at a second time which is past the first time;

an image irregularity determination section determining whether there is an image irregularity or not in the second image stored in the memory based on the traveling condition of the vehicle sensed by the sensor; and

a display control section executing a display control processing to allow the first image stored in the memory to be displayed on the display when the image irregularity determination section determines that there is the image irregularity in the second image.

2. The display system according to claim 1, wherein the sensor includes a speed sensor sensing a speed of the vehicle, and a steering angle sensor sensing an amount of steering of the vehicle, and wherein the image irregularity determination section determines whether there is the image irregularity or not in the second image based on the speed sensed by the speed sensor and the amount of steering sensed by the steering angle sensor.

3. The display system according to claim 1, wherein the sensor includes a vibration sensor sensing a vibration of the vehicle, and wherein the image irregularity determination section determines whether there is the image irregularity or not in the second image based on the vibration sensed by the vibration sensor.

4. The display system according to claim 1, wherein the sensor includes a yaw rate sensor sensing a yaw rate of the vehicle, and wherein the image irregularity determination section determines whether there is the image irregularity or not in the second image based on the yaw rate sensed by the yaw rate sensor.

5. The display system according to claim 1, wherein when the image irregularity determination section determines that the image irregularity exists in the second image, an image processing is further executed with respect to the image taken by the image pick-up device to determine the image irregularity in the second image.

6. A display system for a vehicle, comprising:

a sensor sensing a traveling condition of a vehicle;

an image pick-up device executing an image pick-up to take an image of an outside of the vehicle;

a display displaying the image taken by the image pick-up device;

an image irregularity determination section determining whether there is an image irregularity or not in the image taken by the image pick-up device based on the traveling condition of the vehicle sensed by the sensor; and

a display control section executing a display control processing with respect to the image still containing the image irregularity when the image irregularity determination section determines that there is the image irregularity in the image.

7. The display system according to claim 6, further comprising a memory storing the image taken by the image pick-up device,

wherein when the image irregularity determination section determines that the image irregularity exists in the image, the image still containing the image irregularity stored in the memory is displayed on the display at predetermined time intervals until the image irregularity determination unit determines that the image irregularity does not exist any more.

8. The display system according to claim 6, wherein when the image irregularity determination section determines that the image irregularity exists in the image, the image still containing the image irregularity is displayed on the display with the displaying brightness of the image reduced.

9. The display system according to claim 6, wherein when the image irregularity determination section determines that the image irregularity exists in the image, the image still containing the image irregularity is prohibited from being displayed on the display.

10. The display system according to claim 6, wherein the sensor includes a speed sensor sensing a speed of the vehicle, and a steering angle sensor sensing an amount of steering of the vehicle, and wherein the image irregularity determination section determines whether there is the image irregularity or not in the second image based on the speed sensed by the speed sensor and the amount of steering sensed by the steering angle sensor.

11. The display system according to claim 6, wherein the sensor includes a vibration sensor sensing a vibration of the vehicle, and wherein the image irregularity determination section determines whether there is the image irregularity or not in the second image based on the vibration sensed by the vibration sensor.

12. The display system according to claim 6, wherein the sensor includes a yaw rate sensor sensing a yaw rate of the vehicle, and wherein the image irregularity determination section determines whether there is the image irregularity or not in the second image based on the yaw rate sensed by the yaw rate sensor.

13. The display system according to claim 6, wherein when the image irregularity determination section determines that the image irregularity exists in the second image, an image processing is further executed with respect to the image taken by the image pick-up device to determine the image irregularity in the second image.

14. A method of controlling a display system for a vehicle comprising:

detecting a traveling condition of a vehicle;

picking up an image of an outside of the vehicle;

determining whether there is an image irregularity or not in the image based on the traveling condition of the vehicle; and

executing display processing to display one of the image still containing the image irregularity and the image previously picked up and not containing the image irregularity, on a display, when the image is determined as having the image irregularity.
