Display control apparatus and display system
A display control apparatus performs overlapping display of a highlight image against a notification object that is visually recognized through a picture projection plane of a virtual image display apparatus used by a driver of a vehicle such that the highlight image represents the notification object. A target information acquisition section acquires target information including at least a position and a size of the notification object. A display execution section displays a first highlight image and a second highlight image in a display form capable of identifying each of the first highlight image and the second highlight image based on target information acquired by the target information acquisition section. The first highlight image corresponds to a size of the notification object, while the second highlight image results from enlarging the first highlight image at a predetermined magnification percentage.
1. A display control apparatus for controlling a virtual image display apparatus of a vehicle to display highlight images on a picture projection plane of the vehicle, the highlight images representing an existence of a notification object that is visually recognizable through the picture projection plane by a driver of the vehicle, the display control apparatus comprising:
an electronic control unit configured to:
acquire target information including at least a position and a size of the notification object;
display a first highlight image on the picture projection plane of the vehicle using the virtual image display apparatus; and
display a second highlight image on the picture projection plane of the vehicle using the virtual image display apparatus, the second highlight image corresponding to the first highlight image enlarged at a predetermined magnification percentage,
wherein the first highlight image represents the size of the notification object, and
wherein the second highlight image represents an area where the notification object exists.
2. The display control apparatus according to claim 1 , wherein
the predetermined magnification percentage is set to a value so that the notification object is included in the area indicated by the second highlight image according to a display error based on at least one error among a manufacturing error, an assembly error, and a detection error.
3. The display control apparatus according to claim 1 , wherein
the electronic control unit is further configured to variably set the predetermined magnification percentage according to at least either motion information of the vehicle or a road shape of the vehicle.
4. The display control apparatus according to claim 1 , wherein
the electronic control unit simultaneously displays the first highlight image and the second highlight image.
5. The display control apparatus according to claim 1 , wherein
the electronic control unit switches between the first highlight image and the second highlight image to repeat reduced display and enlarged display, as time advances.
6. The display control apparatus according to claim 5 , wherein
the electronic control unit is further configured to variably set a cycle of the reduced display and the enlarged display based on motion of the notification object.
7. The display control apparatus according to claim 1 , wherein
the electronic control unit displays the first highlight image using a color included in the notification object.
8. The display control apparatus according to claim 1 , wherein
the electronic control unit uses a shape representing the notification object as the first highlight image.
9. A display system comprising:
a virtual image display apparatus; and
the display control apparatus, according to claim 1 , executing a display control using the virtual image display apparatus.
10. The display control apparatus according to claim 1 , wherein
the predetermined magnification percentage is set to a value to cause the second highlight image to represent the area where the notification object exists, according to a display error based on at least one error among a manufacturing error, an assembly error, and a detection error.
11. A display system comprising:
a virtual image display apparatus in a vehicle to display highlight images on a picture projection plane of the vehicle, the highlight images representing an existence of a notification object that is visually recognizable through the picture projection plane by a driver of the vehicle, the images being overlapped with a scene outside of the vehicle through the picture projection plane of the vehicle; and
a display control apparatus executing a display control of the virtual image display apparatus, the display control apparatus comprising:
an electronic control unit configured to:
acquire target information including at least a position and a size of the notification object;
display a first highlight image on the picture projection plane of the vehicle using the virtual image display apparatus; and
display a second highlight image on the picture projection plane of the vehicle using the virtual image display apparatus, the second highlight image corresponding to the first highlight image enlarged at a predetermined magnification percentage,
wherein the first highlight image represents the size of the notification object included in the target information, and
wherein the second highlight image represents an area where the notification object exists.
12. The display system according to claim 11 , wherein
the predetermined magnification percentage is set to a value so that the notification object is included in the area indicated by the second highlight image according to a display error based on at least one error among a manufacturing error, an assembly error, and a detection error.
13. The display system according to claim 11 , wherein
the electronic control unit is further configured to variably set the predetermined magnification percentage according to at least either motion information of the vehicle or a road shape of the vehicle.
14. The display system according to claim 11 , wherein
the electronic control unit simultaneously displays the first highlight image and the second highlight image.
15. The display system according to claim 11 , wherein
the electronic control unit switches between the first highlight image and the second highlight image to repeat reduced display and enlarged display, as time advances.
16. The display system according to claim 15 , wherein
the electronic control unit is further configured to variably set a cycle of the reduced display and the enlarged display based on motion of the notification object.
17. The display control apparatus according to claim 11 , wherein
the electronic control unit displays the first highlight image using a color included in the notification object.
18. The display system according to claim 11 , wherein
the electronic control unit uses a shape representing the notification object as the first highlight image.
19. The display system according to claim 11 , wherein
the predetermined magnification percentage is set to a value to cause the second highlight image to represent the area where the notification object exists, according to a display error based on at least one error among a manufacturing error, an assembly error, and a detection error.
