Abstract

A display system includes a display device mounted on a vehicle, and a controller arranged to control the display of a plurality of pieces of information regarding the vehicle as an image in the display device. If a display fault occurs in a portion of the display device, the controller performs control to display the information displayed in the display fault area having had the display fault, in a normal display area performing a normal display.

Claims

1. A display system comprising:

a display disposed in a vehicle;

a controller arranged and programmed to perform control so as to display, as an image on the display, a plurality of pieces of information including information about the vehicle;

a first table arranged to store information on a smallest visible image size when the plurality of pieces of information including the information about the vehicle are displayed as an image; and

a second table arranged to store at least one or more sets of vertical and horizontal deformation ratios for the image;

wherein

the controller is arranged and programmed to perform control so that, in an event of a display fault in a portion of the display, information displayed in a display fault area with the display fault is deformed by the controller based on the first and second tables and is displayed in a normal display area where normal display is performed.

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

a pattern storage device arranged to store a plurality of pieces of screen layout data indicating in what layout the plurality of pieces of information, including the information about the vehicle, are displayed on the display;

wherein

the image output control section is further arranged to generate display data to be displayed on the display;

based on the screen layout data and the image.

3. The display system according to claim 1, further comprising an importance level rank storage device arranged to store importance levels for at least two of the plurality of pieces of information including the information about the vehicle, and an image output control section arranged to perform control, based on ranks stored in the importance level rank storage device, so as to adjust the information to be displayed and display the information in the normal display area.

4. The display system according to claim 1 wherein when the plurality of pieces of information including the information about the vehicle are displayed as an image in an image size equal to or smaller than the image size stored in the first table, the image output control section is arranged to display the information with numerical values or characters.

5. The display system according to claim 1, further comprising a detector arranged to detect a condition of the display fault area.

6. The display system according to claim 1, further comprising an input device arranged to input the display fault area.

7. The display system according to claim 2, further comprising an input device arranged to perform at least one of:

adding screen layout data to the pattern storage device;

changing the screen layout data stored in the pattern storage device; and

deleting the screen layout data stored in the pattern storage device.

8. The display system according to claim 3, further comprising an input device arranged to perform at least one of:

adding an importance level to the importance level rank storage device;

changing the importance level stored in the importance level rank storage device; and

deleting the importance level stored in the importance level rank storage device.

9. The display system according to claim 1, further comprising an input device perform at least one of:

adding information on a smallest visible image size to the first table;

changing the information on a smallest visible image size stored in the first table; and

deleting the information on a smallest visible image size stored in the first table.

10. The display system according to claim 1, further comprising an input device arranged to perform at least one of:

adding vertical and horizontal deformation ratios to the second table;

changing the vertical and horizontal deformation ratios stored in the second table; and

deleting the vertical and horizontal deformation ratios stored in the second table.

11. A tangible computer-readable storage medium storing a display program that when executed on a computer included in a display system according to claim 1, causes the computer to perform the following steps:

a step of performing control by the controller so as to display, as an image on the display, the plurality of pieces of information including the information on the vehicle; and

a step of displaying, on the display, display data generated by the step of performing control.

12. A display method performed by the display system according to claim 1, the display method comprising:

a step of performing control by the controller so as to display, as an image on the display, the plurality of pieces of information including the information on the vehicle; and

a step of displaying, on the display, display data generated by the control step.

13. A display device disposed in a vehicle, comprising:

a display arranged to display, as an image, a plurality of pieces of information including information about the vehicle;

a first table arranged to store information on a smallest visible image size when the plurality of pieces of information including the information about the vehicle are displayed as an image;

a second table arranged to store at least one or more sets of vertical and horizontal deformation ratios for the image;

an image output control section arranged to deform the image to be displayed based on the first and second tables;

a controller arranged and programmed to perform control so that, in an event of a display fault in a portion of the display, information displayed in a display fault area with the display fault is deformed by the image output control section and is displayed in a normal display area where normal display is performed.
