Abstract

An image display device capable of reducing the burden on a passenger and reducing the occurrence of motion sickness, by giving the passenger, through a visual sense, perception (visually induced self-motion perception) of his/her own body moving while viewing an image of a TV and the like in a vehicle, and thus by matching visual information to vestibular information obtained from the motion of the vehicle, particularly to a sense of rotation and somatosensory information which are detected by his/her semicircular canals, is provided. The image display device includes: a behavior detection section (101) for detecting a behavior of a vehicle; a background image generation section (102) for generating a background image based on the behavior detected by the behavior detection section (101); an image generation section (103) for generating an image; an image transformation section (104) for, based on the behavior detected by the behavior detection section (101), transforming the image generated by the image generation section (103); a composition section (105) for making a composite image of the background image generated by the background image generation section (102) and the image transformed by the image transformation section (104); and a display section (106) for displaying the composite image made by the composition section (105).

Claims

1. An image display device comprising:

a behavior detection section for detecting a behavior of a vehicle;

a background image generation section for generating a background image which moves based on the behavior detected by the behavior detection section;

an image transformation section for transforming an image based on the behavior of the vehicle which is detected by the behavior detection section;

a composition section for making a composite image of the background image generated by the background image generation section and the image transformed by the image transformation section; and

a display section for displaying the composite image made by the composition section.

2. The image display device according to claim 1,

wherein the behavior detection section detects the behavior of the vehicle, using at least one of signals of a velocity sensor, an acceleration sensor, and an angular velocity sensor.

3. The image display device according to claim 1,

wherein the behavior detection section detects the behavior of the vehicle based on a state of an operation performed on the vehicle by a driver of the vehicle.

4. The image display device according to claim 1,

wherein the behavior detection section detects the behavior of the vehicle based on road information acquired from an output from a capture section for capturing an external environment of the vehicle.

5. The image display device according to claim 1,

wherein the behavior detection section detects the behavior of the vehicle based on road information acquired from an output from a navigation section for providing route guidance for the vehicle.

6. The image display device according to claim 1,

wherein the behavior detection section detects one or more of a leftward/rightward acceleration, an upward/downward acceleration, a forward/backward acceleration, and an angular velocity of the vehicle.

7. The image display device according to claim 1,

wherein the background image generation section changes a display position of the background image in accordance with the behavior of the vehicle which is detected by the behavior detection section.

8. The image display device according to claim 1,

wherein in accordance with the behavior of the vehicle which is detected by the behavior detection section, the background image generation section generates the background image which moves to the right when the behavior indicates a left turn and also generates the background images which moves to the left when the behavior indicates a right turn.

9. The image display device according to claim 8,

wherein the background image generation section generates a vertical stripe pattern as the background image.

10. The image display device according to claim 1,

wherein in accordance with the behavior of the vehicle which is detected by the behavior detection section, the background image generation section generates the background image which rotates to the left when the behavior indicates a left turn and also generates the background image which rotates to the right when behavior indicates a right turn.

11. The image display device according to claim 1,

wherein the image transformation section trapezoidal-transforms the image in accordance with the behavior of the vehicle which is detected by the behavior detection section.

12. The image display device according to claim 11,

wherein in accordance with the behavior of the vehicle which is detected by the behavior detection section, the image transformation section trapezoidal-transforms the image by performing any of an enlargement and a reduction of at least one of a left end, a right end, a top end, and a bottom end of the image.

13. The image display device according to claim 1,

wherein the image transformation section enlarges or reduces the image.

14. The image display device according to claim 1,

wherein the composition section makes the composite image such that the background image generated by the background image generation section is placed in a background and the image transformed by the image transformation section is placed in a foreground.

15. The image display device according to claim 14,

wherein in accordance with the behavior of the vehicle which is detected by the behavior detection section, the composition section changes display positions of the background image generated by the background image generation section and of the image transformed by the image transformation section.

26. A vehicle including the image display device according to claim 1.

16-23. -23. (canceled)

24. An image display device comprising:

a behavior detection section for detecting a behavior of a vehicle;

a background image generation section for generating a background image which moves based on the behavior detected by the behavior detection section;

an image transformation section for reducing an image;

a composition section for making a composite image of the background image generated by the background image generation section and the image reduced by the image transformation section; and

a display section for displaying the composite image made by the composition section.

27. A vehicle including the image display device according to claim 24.

25. An image display device comprising:

a behavior detection section for detecting a behavior of a vehicle;

an image transformation section for, based on the behavior detected by the behavior detection section, transforming an image into an image for giving a passenger self-motion perception of himself/herself rotating; and

a display section for displaying the image transformed by the image transformation section.

28. A vehicle including the image display device according to claim 25.
