Abstract: An apparatus includes a processor and a recording medium having a program, the program causing the processor to execute operations. The operations include providing a normal mode and a visible light communication mode, wherein the normal mode and the visible light communication mode are switchable. In the normal mode, first image data is obtained by image capture with a first exposure time by sequentially starting exposure for a plurality of exposure lines in an image sensor each at a different time and each of the plurality of exposure lines partially overlaps in exposure time an adjacent exposure line. In the visible light communication mode, (i) a second exposure time of the image sensor is set, (ii) a bright line image is obtained, and (iii) information is obtained by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image.

Abstract: An information processing program causes a computer to execute: encoding information to be transmitted, to determine a luminance change frequency; 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. In the encoding, each of a first frequency and a second frequency different from the first frequency is determined as the luminance change frequency. In the outputting, 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.
