Information communication method
First 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 a light emitter changing in luminance according to the determined pattern,wherein the pattern of the change in luminance is a pattern in which one of two different luminance values occurs in each arbitrary position in a predetermined duration, andin the determining, the pattern of the change in luminance is determined so that a luminance change position in the duration is different for each of different signals to be transmitted, the luminance change position being a position at which the luminance rises or a position at which the luminance falls.
