Information communication method
An information communication method is provided for transmitting a signal using a change in luminance. The information communication method includes 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. In the determining a pattern, the pattern of the change in luminance is determined by adjusting a first 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.
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 light emitter that changes luminance according to the determined pattern,
wherein, in the determining a pattern, the pattern of the change in luminance is determined by adjusting a first 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 one of a rise and a fall in luminance.
2. An information communication device which transmits a signal using a change in luminance, the information communication device comprising:
a determiner configured to determine a pattern of the change in luminance by modulating a signal to be transmitted; and
a transmitter configured to transmit the signal by causing a light emitter to change luminance according to the determined pattern,
wherein, in the determining a pattern, the pattern of the change in luminance is determined by adjusting a first 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 one of a rise and a fall in luminance.
3. A non-transitory recording medium that stores a program for controlling an information communication device for transmitting a signal using a change in luminance, the program executed by a processor causing the processor of the information communication device to execute:
determining a pattern of the change in luminance by modulating a signal to be transmitted; and
transmitting the signal by a light emitter that changes luminance according to the determined pattern,
wherein, in the determining a pattern, the pattern of the change in luminance is determined by adjusting a first 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 one of a rise and a fall in luminance.
