PROBLEM TO BE SOLVED: To maintain reliability of transmission data by stabilizing the light emission intensity of red light even if the brightness of illumination is changed.SOLUTION: A light communication system comprises: a first light emitting unit for emitting light of a first color; a second light emitting unit for emitting light of a second color different from the first color; a light emission intensity determination unit for determining the light emission intensity of the first light emitting unit and the light emission intensity of the second light emitting unit such that difference between the light emission intensity of the first light emitting unit and the light emission intensity of the second light emitting unit will be equal to or more than a first threshold value if a first value is transmitted; and a light emitting control unit for getting the first light emitting unit and the second light emitting unit to emit light at the light emission intensity determined by the light emission intensity determination unit. |
