Abstract: A transmitter that is difficult to be affected by structural constraints is a transmitter that transmits a signal to a receiver by changing an amount of light emitted, and the transmitter includes: a control unit that generates a control voltage corresponding to a signal to be transmitted; a reflector that reflects sunlight; and a liquid crystal board that receives reflected light that is sunlight reflected by the reflector and changes, according to the control voltage, the amount of light emitted toward the receiver, by allowing the reflected light to pass through the liquid crystal board.

Abstract: A transmitter that is difficult to be affected by structural constraints includes: a liquid crystal board; a first board having translucency; and a second board; and a control unit that changes, by switching transmittance of the liquid crystal board with respect to outside light through application, to the liquid crystal board, of a control voltage corresponding to a signal to be transmitted, an amount of light reflected by the first board and emitted toward the receiver via the liquid crystal board, wherein the control unit maintains, when switching the transmittance of the liquid crystal board to a low transmittance, the transmittance of the liquid crystal board at the low transmittance until the outside light that passed through the liquid crystal board is reflected by the second board and reaches the liquid crystal board.

Abstract: 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.
