Abstract

According to an instruction of a display control device, a head-up display displays display information of individual types in a displayable region of a windshield. The display control device includes a type deciding unit for deciding the types of display information; and a display controller for causing the head-up display to display the display information with the types decided by the type deciding unit in the display areas of the displayable region, the display areas being provided for the individual types of display information, and to display the display guides indicating the display areas regardless of the presence or absence of the display information.

Claims

1. A display control device to control a head-up display that displays a virtual image of display information in a manner as to superimpose the virtual image on a scene outside a moving body, the display control device comprising:

a type decider to decide types of display information; and

a display controller to cause the head-up display to display the display information with the types decided by the type decider, in display areas of the head-up display, the display areas being provided for the individual types of display information, and to display display guides indicating the individual display areas regardless of presence or absence of the display information.

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

a priority order setter to set a priority order of the individual types in accordance with content of the display information; and

a display size setter to set sizes of the individual display areas on a basis of the priority order of the individual types set by the priority order setter, wherein

the display controller changes sizes of the display areas and sizes of the display guides in accordance with the sizes set by the display size setter.

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

a priority order setter to set a priority order of the individual types in accordance with content of the display information; and

a display position setter to set an arrangement order of the individual display areas on a basis of the priority order of the individual types set by the priority order setter, wherein

the display controller changes the arrangement order of the display areas and the display guides in accordance with the arrangement order set by the display position setter.

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

a display area setter to decide the types of display information to be displayed on the head-up display in accordance with a state of the moving body, and for setting the display areas corresponding to the types that are decided to be displayed.

5. The display control device according to claim 1, wherein

the display guides differ in color for the individual types of display information to be displayed in the display areas.

6. The display control device according to claim 5, wherein

colors of the display guides for indicating the display areas are equivalent to colors included in the display information to be displayed in the display areas.

7. The display control device according to claim 1, wherein

the display guides are comprised of a figure, a letter or a combination of the figure and the letter.
