Abstract

A display control device includes an obtainer and a controller. The obtainer obtains a detection accuracy of an object that exists in surroundings of a movable body. When the obtainer obtains a first detection accuracy, the controller controls an image generator so as to generate a first predetermined image that shows a first graphic having a predetermined shape and divided into n regions (n is an integer greater than or equal to 2). When the obtainer obtains a second detection accuracy that is lower than the first detection accuracy, the controller controls the image generator so as to generate a second predetermined image that shows a second graphic having a predetermined shape and undivided or divided into m regions (m is an integer that is greater than or equal to 1 and that is smaller than n).

First claim

What is claimed is:

1. A display control device in a display system including a detection device that detects a predetermined object that exists in surroundings of a movable body, a calculator that calculates a detection accuracy of the detection device, an image generator that generates a predetermined image, and a displayer that outputs the predetermined image on a display medium to display a graphic having a predetermined shape on the display medium, the display control device comprising:
an obtainer that obtains the detection accuracy; and
a controller that controls, based on the detection accuracy, the image generator so as to generate the predetermined image that shows the graphic having a predetermined shape when displayed on the display medium,
wherein the controller:
controls the image generator so as to generate a first predetermined image as the predetermined image, when the obtainer obtains a first detection accuracy, and
controls the image generator so as to generate a second predetermined image as the predetermined image, when the obtainer obtains a second detection accuracy lower than the first detection accuracy,
wherein the first predetermined image shows, as the graphic having a predetermined shape, a first graphic divided into n regions when displayed on the display medium, the first graphic including a divided region, and the second predetermined image shows, as the graphic having a predetermined shape, a second graphic divided into m regions or undivided when displayed on the display medium, the second graphic including a divided region or an undivided region, and
n is an integer greater than or equal to 2, and m is an integer that is greater than or equal to 1 and that is smaller than n.

2. The display control device according to claim 1 ,
wherein the display medium is a windshield of the movable body; and
the displayer displays the graphic having a predetermined shape on the windshield by projecting the predetermined image onto the windshield.

3. The display control device according to claim 1 ,
wherein the display medium is a transmissive display, and the predetermined image is image data; and
the displayer displays the graphic having a predetermined shape on the transmissive display by outputting the image data onto the transmissive display.

4. The display control device according to claim 1 ,
wherein each of the first predetermined image and the second predetermined image includes a highlighted region indicating a positional relationship between the movable body and the predetermined object.

5. The display control device according to claim 4 ,
wherein the graphic having a predetermined shape is a graphic divided into a plurality of regions by one or more lines extending radially from a predetermined reference point; and
the plurality of regions include a first region indicating a direction in which the predetermined object exists relative to the movable body and one or more second regions other than the first region, the first region being displayed in a first display mode, and the one or more second regions being displayed in a second display mode different from the first display mode.

6. The display control device according to claim 4 ,
wherein, in the case where the graphic having a predetermined shape is displayed without being divided,
the controller
controls the image generator so as to generate the predetermined image that shows the predetermined shape in a first mode, when the detection device recognizes the predetermined object, and
controls the image generator so as to generate the predetermined image that shows the predetermined shape in a second mode when the detection device does not recognize the predetermined object.

7. The display control device according to claim 5 ,
wherein, in the case where a division number of the graphic having a predetermined shape and displayed on the display medium changes owing to a change in the detection accuracy,
the controller
controls the image generator so that, when the first region in the graphic having a predetermined shape increases owing to a decrease in the division number, luminance of the first region decreases compared with the luminance thereof before the decrease in the division number, and
controls the image generator so that, when the first region in the graphic having a predetermined shape decreases owing to an increase in the division number, the luminance of the first region increases compared with the luminance thereof before the increase in the division number.

8. The display control device according to claim 1 ,
wherein the graphic having a predetermined shape includes a region indicating a distance between the predetermined object and the movable body.

9. The display control device according to claim 8 ,
wherein the graphic having a predetermined shape is a graphic divided into a plurality of regions by one or more lines that extend in a horizontal direction or one or more lines that extend in an arc direction of a circle having a center at a predetermined reference point; and
the plurality of regions include a third region indicating a distance between the movable body and the predetermined object and one or more fourth regions other than the third region, the third region being displayed in a first display mode, and the one or more fourth regions being displayed in a second display mode different from the first display mode.

10. The display control device according to claim 8 ,
wherein, when the graphic having a predetermined shape is displayed without being divided,
the controller
controls the image generator so as to generate the predetermined image that shows the predetermined shape in a first mode, when the detection device recognizes the predetermined object, and
controls the image generator so as to generate the predetermined image that shows the predetermined shape in a second mode when the detection device does not recognize the predetermined object.

11. The display control device according to claim 9 ,
wherein, in the case where a division number of the graphic having a predetermined shape and displayed on the display medium changes owing to a change in the detection accuracy,
the controller
controls the image generator so that, when the third region in the graphic having a predetermined shape increases owing to a decrease in the division number, luminance of the third region decreases compared with the luminance thereof before the decrease in the division number, and
controls the image generator so that, when the third region in the graphic having a predetermined shape decreases owing to an increase in the division number, the luminance of the third region increases compared with the luminance thereof before the increase in the division number.

12. The display control device according to claim 1 ,
wherein, in the case where a division number of the graphic having a predetermined shape and displayed on the display medium changes owing to a change in the detection accuracy,
the controller controls the image generator so as to display the graphic having a predetermined shape by causing a mode of the graphic before the change in the division number and a mode of the graphic after the change in the division number to be changed in a time series.

13. The display control device according to claim 1 ,
wherein the detection device comprises a first sensor that detects the surroundings of the movable body and a second sensor that detects predetermined weather or an illuminance change;
the detection accuracy is an accuracy of the first sensor;
when the second sensor does not detect the predetermined
