The pulse generator(222) generates a pulse signal matched with data for transmission and outputs the generated pulse signal. The modulator(232) modulates the inputted pulse signal into a signal proper for wireless optical communications. The visible light communication transmitter(212) outputs a visible light signal with a corresponding colour according to a colour control signal. The controller(200) checks a current communication state and the colour of the emitted light according to the current communication state when the user selects the visible light communication mode, and outputs the control signal of the colour of the emitted light to the visible light communication transmitter(212) for outputting the visible light signal with the checked colour of the emitted light.
