Specifically, the display system 1 makes the viewer 100 perceive that the visual object is moving in the depth direction or the front direction as viewed from the observer 100 under dark room conditions, for example.
- a darkroom condition is an environment in which the amount of ambient light surrounding the display system 1 and the viewer is low, and it is desirable that the surrounding devices cannot be seen.
- the screen 22 is arranged parallel to the ground.
- the background image output device 21 projects a background image onto the screen 22 .
- Background image output device 21 may project an image from any direction.
- the optical element 24 (for example, a half mirror) is arranged with an inclination of about 45 degrees, and the aerial image output device 23 is arranged above or below the optical element 24 .

- the video processing device 10 supplies the background video output device 21 with a background video that causes an induced motion in the aerial image. Specifically, the image processing device 10 moves the background image in the direction opposite to the moving direction of the aerial image, thereby causing an induced motion in the aerial image. Induced motion is an illusory phenomenon that gives stationary objects the perception of motion.
- the background image that causes the induced motion is an image that surrounds the aerial image when viewed from the observer's 100 viewpoint. In this embodiment, the floor surface representing the moving range of the aerial image is used as a background image, and the aerial image is perceived as if it is moving on the floor surface. Induced motion will be discussed later.
- the video processing device 10 switches between presence and absence of unevenness for the aerial image according to the background by optical illusion.
- the human visual system has the visual characteristic of perceiving a change in brightness when the contrast changes, even if the physical brightness remains the same. Utilizing this human visual characteristic, in this embodiment, the texture of the aerial image (first texture) is given a change in gradation. Only when the aerial image appears to move on a background to which a texture (second texture) with varying gradation is given, the video processing device 10 can produce a pseudo image due to a change in contrast between the aerial image and the background image in the vicinity of the aerial image. A sense of unevenness is expressed by perceiving a sharp edge change.

- An image 401 is an image when the car is moving on a plane.
- a pseudo edge (thin black line) 421 displayed in the contrast-enhanced image 411 near the tire does not change as long as it moves on the plane. False edges are caused by contrast changes.
- images 402 and 403 are images when the car is moving on an uneven surface.
- Image 412 is a contrast-enhanced image of the tire vicinity of image 402 .
- Image 413 is a contrast-enhanced image near the tire in image 403 .
- the false edge 422 of the contrast-enhanced image 412 at a certain point in time is different from the false edge 423 of the contrast-enhanced image 413 afterward. That is, on the uneven surface, the pseudo edge changes moment by moment as it moves. In this way, when a car moves on an uneven surface, the contrast between the tire and the floor surface changes moment by moment in the vicinity of the tire in the aerial image given the texture with varying gradation. The observer perceives the change of the edges 422 and 423 as the shaking of the tire.

That is, the floor surface of this embodiment may include at least one of the floor, ground, and water surface.
