Abstract

A display device superimposes and displays guide information on an actual image captured by a camera. The display device includes a specifying unit and a display control unit. The specifying unit specifies an overlapping part between guide information and a building in the actual image based on an image-capturing position, position information of the building existing in an image-capturing range of the camera, building shape information of the building, and position information of a facility or a road corresponding to the guide information. The display control unit superimposes and displays the guide information except for a cut-off part on the actual image. The cut-off part herein indicates the overlapping part where the building is to be displayed on a front side of the guide information.

Claims

1. A display device superimposing and displaying guide information on an actual image captured by a camera, comprising:

a specifying unit configured to specify an overlapping part between guide information and a building in the actual image based on an image-capturing position, position information of the building existing in an image-capturing range of the camera, building shape information of the building, and position information of a facility or a road corresponding to the guide information; and

a display control unit configured to superimpose and display the guide information except for a cut-off part on the actual image, the cut-off part indicating the overlapping part where the building is to be displayed on a front side of the guide information,

wherein the display control unit superimposes and displays, on the actual image, a mark indicating a facility as the guide information at a position corresponding to the facility in the actual image, and

wherein the display control unit omits the cut-off part at least regarding the mark corresponding to the facility in the actual image serving as a landmark of route guide.

2. The display device according to claim 1,

wherein the specifying unit specifies the overlapping part by rendering the building in a substantially-transparent state based on the position information and the building shape information of the building and rendering the guide information based on the position information of the facility or the road, and

wherein the display control unit generates a composite image of the building in the substantially-transparent state and the guide information from which the cut-off part is eliminated, and superimposes the composite image on the actual image.

3. The display device according to claim 2,

wherein the display control unit generates the composite image by rendering the building in the substantially-transparent state prior to the guide information and thereafter blending color of the building in the substantially-transparent state with color of the guide information with respect to the overlapping part except for the cut-off part.

4. The display device according to claim 1,

wherein the display control unit superimposes and displays a route where a moving body is going to run on the actual image as the guide information.

5. The display device according to claim 4,

wherein the display control unit displays the route upside-down at a position in a sky above a road corresponding to the route.

7. The display device according to claim 1,

wherein the display control unit displays the mark except for the cut-off part only if the mark corresponds to the facility in the actual image serving as a landmark of route guide.

6. (canceled)

8-9. -9. (canceled)

10. A control method executed by a display device superimposing and displaying guide information on an actual image captured by a camera, the method comprising:

a specifying process for specifying an overlapping part between guide information and a building in the actual image based on an image-capturing position, position information of the building existing in an image-capturing range of the camera, building shape information of the building, and position information of a facility or a road corresponding to the guide information; and

a display control process for superimposing and displaying the guide information except for a cut-off part on the actual image, the cut-off part indicating the overlapping part where the building is to be displayed on a front side of the guide information,

wherein the display control process superimposes and displays, on the actual image, a mark indicating a facility as the guide information at a position corresponding to the facility in the actual image, and

wherein the display control process omits the cut-off part at least regarding the mark corresponding to the facility in the actual image serving as a landmark of route guide.

11. (canceled)

12. A program stored on a non-transitory storage medium and executed by a display device superimposing and displaying guide information on an actual image captured by a camera, the program making the display device function as:

a specifying unit configured to specify an overlapping part between guide information and a building in the actual image based on an image-capturing position, position information of the building existing in an image-capturing range of the camera, building shape information of the building, and position information of a facility or a road corresponding to the guide information; and

a display control unit configured to superimpose and display the guide information except for a cut-off part on the actual image, the cut-off part indicating the overlapping part where the building is to be displayed on a front side of the guide information,

wherein the display control unit superimposes and displays, on the actual image, a mark indicating a facility as the guide information at a position corresponding to the facility in the actual image, and

wherein the display control unit omits the cut-off part at least regarding the mark corresponding to the facility in the actual image serving as a landmark of route guide.
