Abstract: Optical communication apparatuses capable of performing appropriate communication according to a distance to a receiving apparatus, optical communication methods, and an optical communication system are provided. A transmitting apparatus transmits an optical signal corresponding to data. The transmitting apparatus modulates intensity of the optical signal into intensity corresponding to a distance over which the data is to be delivered and outputs this intensity-modulated optical signal. This allows the transmitting apparatus to change the intensity of the optical signal corresponding to the data according to a distance to a receiving apparatus that receives the data, which thus allows the receiving apparatus to surely receive the data.

Abstract: A light source control section 15 selects a first light emitting device arrangement (color combination device group) in which LEDs 19 make a particular visible light color by color synthesis and form one optical communication channel, and then causes the first light emitting device arrangement to emit light, and selects a second light emitting device arrangement so that a light quantity of a light source 18 as a whole becomes uniform, and then causes the selected second light emitting device arrangement to emit light when the first light emitting device arrangement does not emit light. As a result, upon performing optical communication, an optical transmitting apparatus and an optical communication system that can emit an illumination light at a uniform light quantity without generating a flicker of illumination can be realized.
