Abstract

A display control device includes: an acquirer that receives inclination information on an occupant'"'"'s head in a mobile body from a detector that detects the inclination; and a controller that controls a displayer to generate a predetermined image representing a presentation image superimposed on an object as viewed from the occupant when the presentation image is displayed on a display medium, based on recognition results of the object ahead of the mobile body and the inclination information. When the object is recognized, with the head not inclined, the controller causes the displayer to generate a first predetermined image representing a first presentation image indicating a horizontal direction, and with the head inclined, the controller causes the displayer to generate a second predetermined image representing a second presentation image obtained by rotating part of the first presentation image by an angle which is determined according to the inclination.

Claims

1. A display control device comprising:

an acquirer that receives information on an inclination of a head of an occupant in a mobile body from a detector that detects the inclination; and

a controller that controls a displayer to generate a predetermined image based on a result of recognition of an object in front of the mobile body from a recognizer and the inclination information, the predetermined image representing a presentation image to be superimposed on the object as viewed from the occupant when the presentation image is displayed on a display medium,

wherein in the case where the object is recognized,

when the head is not inclined, the controller outputs a control information to the displayer to generate a first predetermined image that represents a first presentation image indicating a horizontal direction, and

when the head is inclined, the controller outputs a control information to the displayer to generate a second predetermined image that represents a second presentation image which is obtained at least by rotating at least part of the first presentation image by an angle which is determined according to the inclination of the head.

2. The display control device according to claim 1,

wherein the controller outputs a control information to the displayer to generate the second predetermined image that represents the second presentation image which is obtained by further applying a predetermined distortion to the first presentation image when the second presentation image is to be displayed on the display medium.

3. A display control method comprising:

obtaining information on an inclination of a head of an occupant in a mobile body from a detector that detects the inclination; and

controlling a displayer to generate a predetermined image based on a result of recognition of an object in front of the mobile body from a recognizer and the inclination information, the predetermined image representing a presentation image to be superimposed on the object as viewed from the occupant when the presentation image is displayed on a display medium,

wherein in the case where the object is recognized,

when the head is not inclined, the display control method further comprises outputting a control information to the displayer to generate a first predetermined image that represents a first presentation image indicating a horizontal direction, and

when the head is inclined, the display control method further comprises outputting a control information to the displayer to generate a second predetermined image that represents a second presentation image which is obtained at least by rotating at least part of the first presentation image by an angle which is determined according to the inclination of the head.

4. A non-transitory computer readable recording medium on which a program is recorded, the program causing a computer to execute:

processing of obtaining information on an inclination of a head of an occupant in a mobile body from a detector that detects the inclination; and

processing of controlling a displayer to generate a predetermined image based on a result of recognition of an object in front of the mobile body from a recognizer and the inclination information, the predetermined image representing a presentation image to be superimposed on the object as viewed from the occupant when the presentation image is displayed on a display medium,

wherein in the case where the object is recognized,

when the head is not inclined, the program further causes the computer to execute outputting a control information to the displayer to generate a first predetermined image that represents a first presentation image indicating a horizontal direction, and

when the head is inclined, the program further causes the computer to execute outputting a control information to the displayer to generate a second predetermined image that represents a second presentation image which is obtained at least by rotating at least part of the first presentation image by an angle which is determined according to the inclination of the head.

5. A projection device comprising:

an acquirer that receives information on an inclination of a head of an occupant in a mobile body from a detector that detects the inclination;

a displayer that generates a predetermined image and displays the predetermined image on a display medium based on a result of recognition of an object in front of the mobile body from a recognizer and the inclination information; and

a controller that controls the displayer to generate a predetermined image that represents a presentation image to be superimposed on the object as viewed from the occupant when the presentation image is displayed on the display medium,

wherein in the case where the object is recognized,

when the head is not inclined, the controller outputs a control information to the displayer to generate a first predetermined image that represents a first presentation image indicating a horizontal direction, and

when the head is inclined, the controller outputs a control information to the displayer to generate a second predetermined image that represents a second presentation image which is obtained at least by rotating at least part of the first presentation image by an angle which is determined according to the inclination of the head.
