Illusion presentation system, and illusion presentation method

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.

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.
