## Abstract

A feeling is given that a stationary object that actually exists as a physical object is moving. In an illusion showing system including: an object; and a video presentation device that presents video for superimposition that includes a stationary object area having a substantially identical contour as a contour of the object, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area, and in which luminance of the luminance varying area varies with time in a luminance range based on luminance of the object and luminance of the background area, the object and the video for superimposition are shown so that a contour of the stationary object area of the video for superimposition presented by the video presentation device substantially matches a contour of the object.

## Claims

### Claim 1

An illusion showing system comprising:
an object; and
a video presentation device that presents video for superimposition that includes a stationary object area having a substantially identical contour as a contour of the object, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area, and in which luminance of the luminance varying area varies with time in a luminance range based on luminance of the object and luminance of the background area, wherein
the object and the video for superimposition are shown so that a contour of the stationary object area of the video for superimposition presented by the video presentation device substantially matches a contour of the object.

### Claim 2

An illusion showing system comprising:
an object that includes a first partial area and a second partial area that is an area other than at least one light-transmitting area located along a contour of the first partial area and the first partial area; and
a video presentation device that presents video for superimposition that includes a stationary object area having a substantially identical contour as a contour of the object, at least one luminance varying area having a substantially identical contour as a contour of the light-transmitting area, and a background area other than the stationary object area and the luminance varying area, and in which luminance of the luminance varying area varies with time in a luminance range based on luminance of the first partial area of the object and luminance of the second partial area of the object, wherein
the object and the video for superimposition are shown so that a contour of the stationary object area of the video for superimposition presented by the video presentation device substantially matches a contour of the first partial area of the object.

### Claim 3 (depends on 1)

The illusion showing system according to claim 1, wherein:
(1) luminance of the object is brighter than luminance of the background area, and a maximum value of luminance of the luminance varying area is smaller than or equal to luminance of the background area; or
(2) luminance of the object is darker than luminance of the background area, and a minimum value of luminance of the luminance varying area is higher than or equal to luminance of the background area.

### Claim 4 (depends on 2)

The illusion showing system according to claim 2, wherein:
(1) luminance of the first partial area is brighter than luminance of the second partial area, and a maximum value of luminance of the luminance varying area is smaller than or equal to luminance of the second partial area; or
(2) luminance of the first partial area is darker than luminance of the second partial area, and a minimum value of luminance of the luminance varying area is higher than or equal to luminance of the second partial area.

### Claim 5 (depends on 2)

The illusion showing system according to any one of claim 2, wherein
the luminance varying area is a portion that does not overlap the stationary object area in at least one area obtained by moving and/or enlarging the stationary object area.

### Claim 6

An illusion showing method using an object and a video presentation device, the method comprising
a step of the video presentation device presenting video for superimposition that includes a stationary object area having a substantially identical contour as a contour of the object, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area, and in which luminance of the luminance varying area varies with time in a luminance range based on luminance of the object and luminance of the background area, wherein
the object and the video for superimposition are shown so that a contour of the stationary object area of the video for superimposition presented by the video presentation device substantially matches a contour of the object.

### Claim 7

An illusion showing method using an object and a video presentation device, wherein
the object includes a first partial area and a second partial area that is an area other than at least one light-transmitting area located along a contour of the first partial area and the first partial area,
the method comprising
a step of the video presentation device presenting video for superimposition that includes a stationary object area having a substantially identical contour as a contour of the object, at least one luminance varying area having a substantially identical contour as a contour of the light-transmitting area, and a background area other than the stationary object area and the luminance varying area, and in which luminance of the luminance varying area varies with time in a luminance range based on luminance of the first partial area of the object and luminance of the second partial area of the object, wherein
the object and the video for superimposition are shown so that a contour of the stationary object area of the video for superimposition presented by the video presentation device substantially matches a contour of the first partial area of the object.
