发明名称 Visible light control apparatus, visible light control circuit, visible light communication apparatus, and visible light control method
摘要 There is provided a visible light control apparatus including: a modulation unit (corresponding to a PPM signal generation circuit, a subcarrier generation circuit, and a first AND circuit) that modulates a subcarrier and thereby generates a modulated signal; a visible light control unit (corresponding to a driving circuit) that controls blinking of visible light which contains information based on the modulated signal modulated by the modulation unit and allows the visible light to be emitted at a predetermined emission time ratio; and an emission time ratio control unit (corresponding to a dimming signal generation circuit, an inverting circuit, a second AND circuit, and an OR circuit) that changes the predetermined emission time ratio and allows the visible light to be emitted at the changed emission time ratio.
