摘要： An information processing program causes a computer to execute: encoding information to be transmitted, to determine a luminance change frequency SA11; and outputting a signal of the determined luminance change frequency to cause a light emitter to change in luminance according to the determined luminance change frequency to transmit the information SA 12. In the encoding SA11, each of a first frequency and a second frequency different from the first frequency is determined as the luminance change frequency. In the outputting SA12, each of a signal of the first frequency and a signal of the second frequency is output as the signal of the determined luminance change frequency, to cause the light emitter to change in luminance according to the first frequency during a first time and change in luminance according to the second frequency during a second time different from the first time after the first time elapses.
