To facilitate creation of presentation data by sharing one presentation data by a plurality of optical presentation apparatuses without creating presentation data individually for each of the optical presentation apparatuses.

The plurality of the optical presentation apparatuses 3 are provided with light emitting diodes of three colors RGB as light sources, and controls light output of each of the light sources by light control data transmitted from a power supply unit 22. The presentation data for specifying timing of light emission and the light output of the light source of each of the optical presentation apparatuses 3 is created by a control device 1. The control device 1 is provided with a group table 11 for registering the optical presentation apparatuses 3 by corresponding to a belonging group, a presentation data setting part 12 for setting the presentation data for every group, and a control data output part 13 for creating control data which includes the presentation data of each group set by the presentation data setting part 12, is registered in the group table 11, and is transmitted to the optical presentation apparatuses 3.
