emission control means for controlling an emission state of the light emitting means bya) controlling the light emitting means to emit the visible light of a first color including ID of the transmitter-side visible communication apparatus as a search processing request, when the search processing request for recognizing the receiver-side visible light communication apparatus which carries out the communication is emitted;
b) controlling the light emitting means to emit the visible light of a second color including ID of the receiver-side visible light communication apparatus which emits communication establishment request and ID of the transmitter-side visible communication apparatus, when the receiver-side visible light communication apparatus which communicates the information communication is specified, based on information from the receiver-side visible light communication apparatus that the search processing request responded and the communication establishment request is emitted toward the specified receiver-side visible light communication apparatus; and
c) controlling the light emitting means to emit the visible light of a third color including transmission data, when the transmission data is emitted to the receiver-side visible light communication apparatus which responded to the communication establishment request based on information included in the visible light received by the light receiving means.

Abstract
A visible light communication apparatus enables an operator to visually recognize a communication state during visual light communication. The apparatus includes a light emitting section which emits visible light and which includes a modulator, a visible light emitter, a light emitting element and an emission control section which includes a controller and which controls an emission state of the visible light from the light emitting section. The apparatus controls the emission state according to the communication state. It is hence possible for the operator to visually perceive the communication state during the visible light communication.
