Abstract:
1. A visible light communication apparatus for transmitting a plurality of communication data signals by using an illumination light, the visible light communication apparatus comprising: an illuminator for generation of the illumination light, the illuminator including a plurality of individual light sources with luminescence center wavelengths on mutually different visible regions; a communication amount adjuster for receipt of each of the plurality of communication data signals, and generation of a dummy data for a corresponding one of the plurality of individual light sources so that data to be transmitted through each of the plurality of light sources has an equal communication amount; and a modulator for receipt of each of the plurality of communication data signals and the dummy data generated therefor, and modulation of each of the received communication data signals and the received dummy data therefor into a driving signal for said each of the plurality of light sources, wherein a combination of the light sources generates a white light.
