Abstract

A driving-support-image generation device of the present invention comprises: a character recognizer that recognizes a character in an image indicative of a message content of a messaging object posted on a road or around a road; and an image processor that generates, based on the character recognized by the character recognizer and driving-support information related to the character, a driving-support image obtained by modifying the image of the messaging object into an image matched to the driving-support information.

First claim

1 .- 17 . (canceled)

18 . A driving-support-image generation device comprising:
a character recognizer that recognizes a character in an image indicative of a message content of a messaging object posted on a road or around a road; a vehicle-information determination processor that determines whether or not the character recognized by the character recognizer corresponds to information related to a vehicle of a host vehicle; and an image processor that generates a driving-support image in which the character that has been determined to correspond to the information related to the vehicle of the host vehicle by the vehicle-information determination processor is highlighted.

19 . The driving-support-image generation device of claim 18 , wherein an image captured by an image capturing device is used as the image indicative of the message content of the messaging object.

20 . The driving-support-image generation device of claim 19 , further comprising an image-quality determination processor that determines an image quality of the driving-support image generated by the image processor, wherein
the image processor generates, when the image quality of the driving-support image is determined to be lower than a threshold value set in the image-quality determination processor, a driving-support image in which the character recognized by the character recognizer is highlighted.

21 . A driving-support-image display device, comprising a display that displays, when a character in an image indicative of a message content of a messaging object posted on a road or around a road is the character corresponding to information related to a vehicle of a host vehicle, a driving-support image in which the character in the image indicative of the message content of the messaging object is highlighted.

22 . The driving-support-image display device of claim 21 , wherein the display uses an image captured by an image capturing device, as the image indicative of the message content of the messaging object.

23 . The driving-support-image display device of claim 22 , wherein, the display, when an image quality of the image captured by the image capturing device is lower than a setup threshold value, displays a driving-support image in which the character in the image captured by the image capturing device is highlighted.

24 . The driving-support-image display device of claim 21 , wherein the display, when a passenger does not recognize the messaging object, displays the driving-support image.

25 . A driving-support-image display system, comprising:
an image capturing device that captures a messaging object posted on a road or around a road; a driving-support-image generation device which comprises: a character recognizer that recognizes a character in an image indicative of a message content of the messaging object captured by the image capturing device; a vehicle-information determination processor that determines whether or not the character recognized by the character recognizer corresponds to information related to a vehicle of a host vehicle; and an image processor that generates a driving-support image in which the character that has been determined to correspond to the information related to the vehicle of the host vehicle by the vehicle-information determination processor is highlighted; and a display that displays the driving-support image generated by the driving-support-image generation device.

26 . A driving-support-image generation program that causes a computer to implement:
character recognition processing of recognizing a character in an image indicative of a message content of a messaging object posted on a road or around a road; a vehicle-information determination processing of determining whether or not the character recognized by the character recognizer corresponds to information related to a vehicle of a host vehicle; and an image processing of generating a driving-support image in which the character that has been determined to correspond to the information related to the vehicle of the host vehicle by the vehicle-information determination processor is highlighted.
