Abstract

A display control device configured to control a head-up display that projects an image onto an area ahead of a driver to display the image such that the image that is a virtual image is superimposed on an actual view. The display control device includes a controller. The controller is configured to execute control such that a highlighting image that highlights a specific object present ahead of a vehicle is displayed when a warning against the specific object is given to the driver. The specific object is detected based on traveling situation information regarding a traveling situation of the vehicle. The traveling situation information based on an output from a vehicular sensor including an on-board camera.

First claim

What is claimed is:

1. A display control device configured to control a head-up display that projects an image onto an area ahead of a driver to display the image such that the image that is a virtual image is superimposed on an actual view,
the display control device comprising a controller configured to execute control such that a highlighting image that highlights a specific object present ahead of a vehicle is displayed when a warning against the specific object is given to the driver, the specific object being detected based on traveling situation information regarding a traveling situation of the vehicle, and the traveling situation information being based on an output from a vehicular sensor including an on-board camera;
wherein the highlighting image is displayed in a vicinity of the specific object at a position shifted from the specific object in a traveling direction of the specific object, the highlighting image having a shape corresponding to the specific object;
wherein the controller is configured to determine a speed of the specific object; and
wherein an amount that the position of the highlighting image is shifted from the specific object is based on the speed of the specific object.

2. The display control device according to claim 1 , wherein the controller is configured to derive a level of emergency based on the traveling situation information and to vary the highlighting image depending on the level of emergency.

3. The display control device according to claim 2 , wherein the controller is configured to execute control such that the highlighting image that makes the specific object more conspicuous is displayed as the level of emergency is higher.

4. The display control device according to claim 1 , wherein the controller is configured to execute control such that the highlighting image is displayed only when an emergent situation for traveling of the vehicle has occurred.

5. A display control method of controlling a head-up display that projects an image onto an area ahead of a driver to display the image such that the image that is a virtual image is superimposed on an actual view,
the display control method comprising:
acquiring traveling situation information regarding a traveling situation of a vehicle based on an output from a vehicular sensor including an on-board camera;
displaying a highlighting image which highlights a specific object that is present ahead of the vehicle and that is detected based on the traveling situation information, when a warning against the specific object is given to the driver, the highlighting image is displayed in a vicinity of the specific object at a position shifted from the specific object in a traveling direction of the specific object, the highlighting image having a shape corresponding to the specific object;
determining a speed of the specific object; and
shifting the position of the highlighting image from the specific object based on the speed of the specific object.

6. The display control device according to claim 1 , wherein the controller is configured to derive a level of emergency based on the traveling situation information; and
wherein an amount that the position of the highlighting image is shifted from the specific object is based on the level of emergency.

7. The display control method according to claim 5 , further comprising deriving a level of emergency based on the traveling situation information; and
shifting the position of the highlighting image from the specific object based on the level of emergency.
