Claim:
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, wherein in the determining, a third luminance change pattern indicating an other header different from the header is determined, and in the transmitting, the header, the body, and the other header are transmitted by the at least one light emitter changing in luminance according to the first luminance change pattern, the second luminance change pattern, the first luminance change pattern, and the third luminance change pattern in the stated order.
