Abstract

A vehicle image processing system including a control unit and a display unit. The control unit processes an image of the exterior of the vehicle. The display unit displays at least a part of the image. The control unit operates the display unit in first and second modes. The first mode displays at least a part of the image, and the second mode displays at least first and second adjacent regions. The second region is located at least in a lateral end of the display unit, where in the first region the display unit displays part of the image displayed in the first mode, and in the second region the display unit removes the part of the image not displayed in the first region.

Claims

1. A vehicle image processing system for a vehicle comprising:

a control unit configured to process an image of the exterior environment of the vehicle; and

a display unit configured to display at least a part of the image processed by the control unit, the control unit being configured to operate the display unit in at least two modes including a first mode where the display unit is configured to display at least a part of the image processed by the control unit, and a second mode where the display unit is configured to display at least first and second adjacent regions, and the second region being located at least in a lateral end of the display unit, and wherein the first region of the display unit is configured to display part of the image processed by the control unit with the same scale of the image displayed in the first mode, and in the second region the display unit is configured to remove the part of the image not displayed in the first region corresponding to the lateral end of the image displayed in the first mode so that at least one lateral end of the displayed image is hidden in the second mode, wherein the display unit is configured to display an area with a neutral color with low bright in the second region of the second mode of operation for removing the at least lateral end of the image displayed in the first mode, and the control unit is configured to receive at least one parameter each having increasing and decreasing values and related to the movement of the vehicle, and wherein the control unit is configured to send a signal to the display unit to change the mode of operation according to a value of the increasing and decreasing values of the parameter.

2. The vehicle image processing system according to claim 1, wherein the neutral color is a dark color.

3. The vehicle image processing system according claim 1, wherein the parameter is the speed of the vehicle such that the control unit is configured to send a signal to the display unit to change the mode of operation according to the value of the speed of the vehicle.

4. The vehicle image processing system, according claim 1, wherein the parameter is the angle of the steering wheel of the vehicle such that the control unit is configured to send a signal to the display unit to change the mode of operation according to the value of the steering wheel.

5. The vehicle image processing system according claim 1, wherein the parameter is the driving mode of the vehicle such that the control unit is configured to send a signal to the display unit to change the mode of operation according to the driving mode of the vehicle.

6. The vehicle image processing system according to claim 1, wherein the control unit is configured to send a signal to the display unit to increase the size of the second region when the value of the parameter increases.

7. The vehicle image processing system according to claim 1, further comprising:

an image processing unit connected to the control unit configured to detect objects in the image processed by the control unit.

8. The vehicle image processing system according to claim 1, wherein the second region comprises at least two lateral ends of the display unit.

9. The vehicle image processing system according to claim 1, further comprising:

a capturing unit connected to the control unit and mountable on the vehicle, the capturing unit being configured to obtain an image of the exterior environment of the vehicle.

10. A vehicle image processing system for a vehicle comprising:

a control unit configured to process an image of the exterior environment of the vehicle;

a display unit configured to display at least a part of the image processed by the control unit, the control unit being configured to operate the display unit in at least two modes including a first mode where the display unit is configured to display at least a part of the image processed by the control unit, and a second mode where the display unit is configured to display at least first and second adjacent regions, and the second region being located at least in a lateral end of the display unit, and where in the first region the display unit is configured to display part of the image processed by the control unit with the same scale of the image displayed in the first mode, and in the second region the display unit is configured to remove the part of the image not displayed in the first region corresponding to the lateral end of the image displayed in the first mode so that at least one lateral end of the displayed image is hidden in the second mode; and

an image processing unit connected to the control unit configured to detect objects in the image processed by the control unit.

11. The vehicle image processing system, according to claim 10, wherein the image processing unit is configured to detect the lateral limits of a road in the processed image and the control unit is configured to send a signal to the display unit to change to the second mode of operation where the display unit is configured to remove from the displayed image a second region located between the road limits and the edges of the displayed image.

12. The vehicle image processing system according to claim 11, wherein the display unit is configured to display a dark area located between the road limits and the edges of the display unit.

13. The vehicle image processing system according to claim 12, wherein the displayed image is a digital image and the control unit is configured to measure the frequency of changes in pixels of the digital image and where the control unit is configured to send a signal to the display unit to remove from the displayed image pixels according to the value of its frequency of change.

14. A vehicle image processing system for a vehicle comprising:

a control unit configured to process an image of the exterior environment of the vehicle; and

a display unit configured to display at least a part of the image processed by the control unit, the control unit being configured to operate the display unit in at least two modes including a first mode where the display unit is configured to display at least a part of the image processed by the control unit, and a second mode where the display unit is configured to display at least first and second adjacent regions, and the second region being located at least in a lateral end of the display unit, and wherein the first region of the display unit is configured to display part of the image processed by the control unit with the same scale of the image displayed in the first mode, and in the second region the display unit is configured to remove the part of the image not displayed in the first region corresponding to the lateral end of the image displayed in the first mode so that at least one lateral end of the displayed image is hidden in the second mode, wherein the displayed image is a digital image and the control unit is configured to measure the frequency of changes in pixels of the digital image and where the control unit is configured to send a signal to the display unit to remove from the displayed image pixels according to the value of its frequency of change.
