Abstract

In an image display system, a manipulation signal obtaining unit obtains a manipulation signal in accordance with manipulation of manipulation switches. A display control unit controls to display a plurality of switch indicators, which are selectable based on the manipulation signal, on a display screen. A storing unit stores correspondences between the manipulation signal and a display content to be displayed next on the display screen, for the respective switch indicators. The display control unit determines the display content to be displayed next based on the manipulation signal obtained by the manipulation signal obtaining unit and the correspondence stored in the storing unit, and displays the determined display content on the display screen.

Claims

1. An image display system comprising:

a manipulation signal obtaining unit for obtaining a manipulation signal in accordance with manipulation of a manipulation switch;

a display control unit for displaying a plurality of switch indicators, which are selectable based on the manipulation signal, on a display screen; and

a storing unit for storing correspondences between the manipulation signal and a display content to be displayed next on the display screen, for the respective switch indicators, wherein

the display control unit determines the display content to be displayed next based on the manipulation signal obtained by the manipulation signal obtaining unit and the correspondence stored in the storing unit and displays the determined display content on the display screen.

2. The image display system according to claim 1, wherein

the display control unit displays a plurality of screen sections on the display screen,

the display content includes a screen section to be activated next,

the storing unit stores correspondences between the manipulation signal and the screen section to be activated next, for the respective switch indicators, and

the display control unit displays a predetermined screen section of the screen sections as activated, based on the obtained manipulation signal and the stored correspondence.

3. The image display system according to claim 1, wherein

the display content includes a switch indicator to be selected next,

the storing unit stores correspondences between the manipulation signal and the switch indicator to be selected next, for the respective switch indicators, and

the display control unit displays a predetermined switch indicator of the switch indicators as selected, based on the obtained manipulation signal and the stored correspondence.

4. The image display system according to claim 1, wherein

the display control unit displays the switch indicators in a form of list on the display screen,

the display content includes an instruction to scroll the listed switch indicators,

the storing unit stores correspondences between the manipulation signal and the instruction to scroll the listed switch indicators, for the respective switch indicators, and

the display control unit scrolls the listed switch indicators based on the obtained manipulation signal and the stored correspondence.

5. The image display system according to claim 4, further comprising:

an uppermost row determining unit for determining whether a switch indicator selected based on the manipulation signal is located at an uppermost row of the list; and

an upward operation determining unit for determining whether the obtained manipulation signal indicates an upward operation, wherein

the display control unit scrolls the list downward based on the stored correspondence, when it is determined that the selected switch indicator is located at the uppermost row of the list and the obtained manipulation signal indicates the upward operation.

6. The image display system according to claim 4, further comprising:

a lowermost row determining unit for determining whether a switch indicator selected based on the manipulation signal is located at a lowermost row of the list; and

a downward operation determining unit for determining whether the obtained manipulation signal indicates a downward operation, wherein

the display control unit scrolls the list upward based on the stored correspondence, when it is determined that the selected switch indicator is located at the lowermost row of the list and the obtained manipulation signal indicates the downward operation.

7. The image display system according to claim 1, wherein

the display control unit provides a first mode in which the selectable switch indicators are displayed on the display screen and a second mode in which a map screen is scrolled on the display screen,

the storing unit stores first key information for the first mode and second key information for the second mode, and

the display control unit obtains the first key information in the first mode and the second key information in the second mode.

8. The image display system according to claim 2, wherein

the display content includes a switch indicator to be selected next,

the storing unit stores correspondences between the manipulation signal and the switch indicator to be selected next, for the respective switch indicators, and

the display control unit displays a predetermined switch indicator of the switch indicators as selected based on the obtained manipulation signal and the stored correspondence.

9. The image display system according to claim 2, wherein

the display control unit provides a first mode in which the selectable switch indicators are displayed on the display screen and a second mode in which a map screen is scrolled on the display screen,

the storing unit stores first key information for the first mode and second key information for the second mode, and

the display control unit obtains the first key information in the first mode and the second key information in the second mode.
