The control unit 160 controls at least one of the first image, the second image, the sound, or the light. Specifically, the control unit 160 can use a media server (Media Server) or the like. Moreover, the synchronization point of the first image, the second image, the sound, or the light by the control unit 160 can be based on the waveform information of the first image, the second image, the sound, or the light or the accompanying information (the date and place of the data creation) After setting, etc., it can be set according to the person's designated operation. The term "synchronization" as used herein refers to the timing at which the start and end of projection, display, output, or illumination for each scene, and the change in intensity or tone are at the same time. The control unit 160 creates a synchronized time line based on the set synchronization point. The control unit 160 generates a control command based on the created time line, and transmits the control command to the video projection unit 110, the second display unit 130, the acoustic unit 140, or the light source unit 150, thereby enabling the first image and the first image.

By this synchronization, a stereoscopic image such as a fairy can be automatically displayed as the first video on the first display unit 120, and in the scene in which the fairy appears, the sound corresponding to the appearance is started to be output in accordance with the appearance. Further, when the light source unit 150 irradiates light onto the first image projected on the first display unit 120, for example, a shadow may be generated, that is, the shadow is compared with the shadow of a person on the stage or the like. Shapes with different angles, widths, elongations, and directionalities, and varying degrees of shading. Therefore, the control unit 160 can adjust the shadow formed by the irradiation of the light source unit 150 by adjusting the tilt angle and the tilt direction of the light source unit 150 or by adjusting the opening or closing (ON/OFF) of the illumination, for example. The degree of shading of the person's shadow on the stage, the angle, the width, the amount of elongation, and the directionality of the shadow shape, etc., respectively, the degree of shading of the shadow of the person projected in the first image, and the angle, width, elongation, and directivity of the shadow shape. the same. With this adjustment, a more natural stereoscopic image space can be realized. Furthermore, the control unit 160 may also adjust the light emitted by the light source unit 150 such that when the light source unit 150 irradiates light onto the first image projected on the first display unit 120, the color of the first image (hue, Saturation or lightness does not change, for example, there is no difference between the color of the first image and the color (hue, saturation, or lightness) of the person on the stage.
