Abstract

A driving-support-image generation device of the present invention includes: a driving-support-image memory that stores a plurality of driving-support images each indicative of a message content of a messaging object posted on a road or around a road; and an image generator that selects from among the driving-support images stored in the driving-support-image memory, one or plural driving-support images on the basis of a pre-set order of priority, and generates using the thus-selected driving-support images, an image to be displayed on a display in a vehicle.

First claim

The invention claimed is:

1. A driving-support-image generation device configured to receive driving support images to-be-obtained from a camera mounted on a vehicle comprising:
a driving-support-image memory that stores a plurality of driving-support images each indicative of a message content of a messaging object posted on or around a road on which the vehicle is traveling; and
an image generator that
selects, from among the driving-support images stored in the driving-support-image memory on a basis of a pre-set order of priority identified by a passenger selected display mode selected from among plural display modes having different orders of priority of image display, one or plural driving-support images, each indicative of the message content of the messaging object having been passed by the vehicle that travels on the road to a destination point, and
generates, using the thus-selected driving-support images, an image to be displayed on a display in the vehicle.

2. The driving-support-image generation device of claim 1 , wherein the driving-support-image memory stores the driving-support images to be each associated with information related to a vehicle location; and
wherein the image generator selects, based on the information related to a vehicle location, the driving-support images to be used for the generation of said image, from among the plurality of driving-support images stored in the driving-support-image memory.

3. The driving-support-image generation device of claim 1 , further comprising a sight-line detection determination device that determines whether or not a passenger in the vehicle has recognized the messaging object,
wherein, the driving-support-image memory performs said storing so that information from the sight-line detection determination device being indicative that the messaging object has not been recognized by the passenger in the vehicle, is associated correspondingly, when so determined; and
wherein the image generator preferentially selects the driving-support image associated with the information indicative that the messaging object has not been recognized, from among the driving-support images stored in the driving-support-image memory.

4. The driving-support-image generation device of claim 1 , wherein the image generator generates a selective display that allows a passenger to select the driving-support image to be displayed, using the selected driving-support images or identification information corresponding to the driving-support images.

5. The driving-support-image generation device of claim 1 , wherein the image generator selects the plural driving-support images from among those stored in the driving-support-image memory and generates the image in which the thus-selected plural driving-support images are displayed simultaneously.

6. The driving-support-image generation device of claim 1 , further comprising a messaging-object-content determination processor that determines a content of the messaging object;
wherein the driving-support-image memory stores the driving-support images to be each associated with information indicative of the content of the messaging object determined by the messaging-object-content determination processor; and
wherein the image generator selects based on the content of the messaging object, the driving-support image to be used for the generation of said image, from among the plurality of driving-support images stored in the driving-support-image memory.

7. The driving-support-image generation device of claim 6 , wherein the image generator selects the plural driving-support images of messaging objects having different types of contents, from among the plurality of driving-support images stored in the driving-support-image memory, and generates said image for each of the types on the basis of the thus-selected plural driving-support images.

8. A driving-support-image display device configured to receive driving support images obtained from a camera mounted on a vehicle comprising:
a display that displays a driving-support image indicative of a message content of a messaging object posted on or around a road on which a vehicle is traveling,
wherein the display displays an image including the driving-support images indicative of the contents of one or plural messaging objects having been passed by the vehicle that travels on a road to a destination point, the one or plural messaging objects being selected from among a plurality of messaging objects on the basis of a pre-set order of priority identified by a passenger selected display mode selected from among plural display modes having different orders of priority of image display.

9. The driving-support-image display device of claim 8 , wherein the display displays the image on the basis of the order of priority being set according to a vehicle location.

10. The driving-support-image display device of claim 8 , wherein the display displays the image including the driving-support images indicative of the contents of one or plural messaging objects selected on the basis of said order of priority, when a passenger in the vehicle does not recognize the messaging objects.

11. The driving-support-image display device of claim 8 , wherein the display displays a selection screen that allows a passenger to select the driving-support image to be displayed.

12. The driving-support-image display device of claim 8 , wherein the display simultaneously displays the plural driving-support images.

13. A driving-support-image display system, comprising:
a camera that captures a messaging object posted on a road or around a road on which a vehicle is traveling, and
a driving-support-image display device which comprises:
a driving-support-image memory that stores a plurality of driving-support images each indicative of a message content of the messaging object captured by the camera;
an image generator that
selects, from among the driving-support images stored in the driving-support-image memory on a basis of a pre-set order of priority identified by a passenger selected display mode selected from among plural display modes having different orders of priority of image display, one or plural driving-support images each indicative of the message content of the messaging object having been passed by the vehicle that travels on the road to a destination point, and
generates an image to be displayed, on the basis of the thus-selected driving-support images; and
a display in a vehicle that displays the image generated by the image generator.

14. The driving-support-image display device of claim 8 , wherein the display displays the image on the basis of the order of priority being set according to the content of the messaging object.

15. The driving-support-image display device of claim 14 , wherein the display displays the driving-support images indicative of the messaging objects having different types of contents, for each of the types as said image.

16. A non-transitory computer readable medium storing a driving-support-image generation program that causes a computer to be configured to receive driving support images to be obtained from a camera mounted on a vehicle and to implement:
processing and storing a plurality of the driving-support images, into a driving-support-image memory, each of the driving-support images indicative of a message content of a messaging object posted on or around a road on which the vehicle is traveling;
image generation processing of selecting from among the driving-support images stored in the driving-support-image memory on a basis of a pre-set order of
