Abstract:
1. An information communication method for transmitting a signal using a change in luminance, the information communication method comprising: determining a pattern of the change in luminance by modulating a signal to be transmitted; and transmitting the signal by a display, which comprises a light emitter that changes luminance according to the determined pattern, wherein, in the transmitting of the signal, when the display is adjacent to an other display and each of the display and the other display transmit a signal by changing luminance, the display changes luminance in an area of the display other than a non-transmission area that is near the other display, without changing luminance in the non-transmission area, and wherein, in the determining a pattern, the pattern of the change in luminance is determined by adjusting a time from one change in luminance to a next change in luminance according to the signal, the one change in luminance and the next change in luminance being a same one of a rise and a fall in luminance.
