Abstract

An information communication method of transmitting a signal using a change in luminance is provided. The information communication method includes: determining a pattern of the change in luminance, by modulating the signal to be transmitted; and transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance. In the determining, a first luminance change pattern corresponding to a body which is a part of the signal and a second luminance change pattern indicating a header for specifying the body are determined. In the transmitting, the header and the body are transmitted by the at least one light emitter changing in luminance according to the first luminance change pattern, the second luminance change pattern, and the first luminance change pattern in the stated order.

Claims

1. An information communication method of transmitting a signal using a change in luminance, the information communication method comprising:

determining a pattern of the change in luminance, by modulating the signal to be transmitted; and

transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance,

wherein, in the determining, a first luminance change pattern corresponding to a body which is a part of the signal and a second luminance change pattern indicating a header for specifying the body are determined, and

in the transmitting, the header and the body are transmitted by the at least one light emitter changing in luminance according to the first luminance change pattern, the second luminance change pattern, and the first luminance change pattern in the stated order.

2. An information communication device that transmits a signal using a change in luminance, the information communication device comprising:

a processor; and

a memory storing instructions that, when executed by the processor, cause the processor to perform operations including;

determining a pattern of the change in luminance, by modulating the signal to be transmitted; and

transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance,

wherein, in the determining, a first luminance change pattern corresponding to a body which is a part of the signal and a second luminance change pattern indicating a header for specifying the body are determined, and

in the transmitting, the header and the body are transmitted by the at least one light emitter changing in luminance according to the first luminance change pattern, the second luminance change pattern, and the first luminance change pattern in the stated order.

3. A non-transitory computer-readable recording medium storing a program for transmitting a signal using a change in luminance, the program, when executed by a computer, causing the computer to perform a process comprising:

determining a pattern of the change in luminance, by modulating the signal to be transmitted; and

transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance,

wherein, in the determining, a first luminance change pattern corresponding to a body which is a part of the signal and a second luminance change pattern indicating a header for specifying the body are determined, and

in the transmitting, the header and the body are transmitted by the at least one light emitter changing in luminance according to the first luminance change pattern, the second luminance change pattern, and the first luminance change pattern in the stated order.
