Abstract

A method of controlling a display control apparatus in a display system includes causing a display unit to generate a first certain image indicating a first presentation image to be overlapped on a certain object in display on a display medium on the basis of the recognized certain object; determining a wiping area wiped by a wiper on the display medium on the basis of detected position after the first presentation image is displayed on the display medium; and causing the display unit to generate a second certain image indicating a second presentation image resulting from deletion of a portion corresponding to the wiping area in the first presentation image in the display on the display medium.

Claims

1. A method of controlling a display control apparatus in a display system including a recognition unit that recognizes a certain object existing in a front direction or a side direction of a movable body, a detection unit that detects a position of a wiper, which wipes a display medium at least including a windshield of the movable body, and a display unit that generates a certain image to display the certain image on the display medium, the method comprising:

causing the display unit to generate a first certain image indicating a first presentation image to be overlapped on the certain object on the display medium on the basis of the recognized certain object;

determining a wiping area wiped by the wiper on the display medium on the basis of detected position of the wiper after the first presentation image is displayed on the display medium; and

causing the display unit to generate a second certain image indicating a second presentation image resulting from deletion of a portion corresponding to the wiping area in the first presentation image on the display medium.

2. A method of controlling a display control apparatus according to claim 1,

wherein, if a certain time elapsed since the display unit is caused to generate the second certain image, the display unit is caused to generate a third certain image indicating a third presentation image including the portion corresponding to the wiping area in the first presentation image on the display medium.

3. A method of controlling a display control apparatus according to claim 1,

wherein, if a first certain time elapsed since the display unit is caused to generate the second certain image, the display unit is caused to generate a fourth certain image indicating a fourth presentation image in which a portion to be overlapped on the wiping area in the first presentation image is displayed in a first aspect on the display medium, and

wherein, if a second certain time longer than the first certain time elapsed since the display unit is caused to generate the second certain image, the display unit is caused to generate a fifth certain image indicating a fifth presentation image in which the portion to be overlapped on the wiping area in the first presentation image is displayed in a second aspect.

4. A method of controlling a display control apparatus according to claim 3,

wherein each of the first aspect and the second aspect is at least one of a luminance, a color, a shape, and a size of the corresponding presentation image.

5. A method of controlling a display control apparatus according to claim 1, further comprising:

determining whether a distance from the movable body to the recognized certain object is lower than or equal to a predetermined threshold value,

wherein the display unit is caused to generate the first certain image indicating the first presentation image to be overlapped on the certain object on the display medium only for the object the distance of which from the movable body is lower than or equal to the predetermined threshold value.

6. A display control apparatus in a display system including a recognition unit that recognizes a certain object existing in a front direction or a side direction of a movable body, a detection unit that detects a position of a wiper, which wipes a display medium at least including a windshield of the movable body, and a display unit that displays a certain image generated on the basis of a result of the recognition by the recognition unit on the display medium, the display control apparatus comprising:

a determination unit that determines a wiping area wiped by the wiper on the display medium on the basis of detected position; and

a control unit that controls the display unit so as to generate the certain image indicating a presentation image to be overlapped on the certain object in an area other than the determined wiping area on the display medium on the basis of the recognized certain object.

7. The display control apparatus according to claim 6,

wherein the determination unit determines whether the wiper has worked on the basis of the detected position and, if the determination unit determines that the wiper has worked, the determination unit determines the wiping area.

8. The display control apparatus according to claim 6, further comprising:

a measurement unit that measures an elapsed time, which indicates a time elapsed since the wiping by the wiper,

wherein, if the elapsed time after wiping exceeds a predetermined threshold value, the control unit controls the display unit so as to generate the presentation image in the wiping area.

9. The display control apparatus according to claim 8,

wherein the control unit acquires information about a working interval of the wiper and sets the predetermined threshold value so as to be increased with the increasing working interval of the wiper.

10. The display control apparatus according to claim 8,

wherein the control unit acquires information about a velocity of the movable body and sets the predetermined threshold value so as to be decreased with the increasing velocity of the movable body.

11. The display control apparatus according to claim 8,

wherein the control unit acquires information about a degree of viewability of the display medium and sets the predetermined threshold value so as to be decreased with the reducing viewability.

12. The display control apparatus according to claim 8,

wherein the control unit controls the display unit so as to generate the presentation image in a first aspect in the wiping area after a first elapsed time elapsed and generate the presentation image in a second aspect in the wiping area after a second elapsed time later than the first elapsed time after wiping elapsed.

13. The display control apparatus according to claim 12,

wherein each of the first aspect and the second aspect is at least one of a luminance, a color, a shape, and a size of the corresponding presentation image.

14. A display apparatus in a display system including a recognition unit that recognizes a certain object existing in a front direction or a side direction of a movable body and a detection unit that detects a position of a wiper, which wipes a display medium at least including a windshield of the movable body, the display apparatus comprising:

a display unit that generates a certain image to display the certain image on the display medium;

a determination unit that determines a wiping area wiped by the wiper on the basis of detected position; and

a control unit that, if the certain object is recognized by the recognition unit, controls the display unit so as to generate the certain image indicating a presentation image to be overlapped on the certain object in an area other than the wiping area.
