Abstract:
In the present invention, an information processing program causes a computer to execute the following steps: a determination step (SA11) for determining frequencies of brightness changes, by encoding information to be sent; and an output step (SA12) for outputting signals indicating the determined brightness change frequency so that a light-emitting body sends the information to be sent by undergoing brightness change in accordance with the determined brightness change frequency. The determination step (SA11) is for determining that a first frequency and a second frequency differing from the first frequency are brightness change frequencies. The output step (SA12) is for outputting signals indicating the first and second frequencies as signals indicating the determined brightness change frequency, so that the light-emitting body undergoes brightness change in accordance with the first frequency during a first time period and, after the first time period has elapsed, undergoes brightness change in accordance with the second frequency during a second time period which differs from the first time period.
