Information communication method
An information communication method is provided that determines a pattern of a change in luminance by modulating a signal to be transmitted, and outputs the determined pattern to a light emitter that changes in luminance according to the determined pattern. In the method, the signal includes a first data, a first header of the first data, second data, and a second header of the second data. Additionally, the pattern of the change in luminance is determined according to in an order of (i) the first data, (ii) the first header, (iii) the first data, (iv) the second data, (v) the second header, and (vi) the second data.
1. An information communication method, comprising:
determining a pattern of a change in luminance by modulating a signal to be transmitted; and
outputting the determined pattern to a light emitter that changes in luminance according to the determined pattern,
wherein the signal includes a first data, a first header of the first data, second data, and a second header of the second data, and
wherein, in the determining, the pattern of the change in luminance is determined according to in an order of (i) the first data, (ii) the first header, (iii) the first data, (iv) the second data, (v) the second header, and (vi) the second data.
2. The information communication method according to claim 1 ,
wherein, in the determining, the pattern of the change in luminance is determined by adjusting a 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. The information communication method according to claim 1 ,
wherein the first header is used in demodulating the first data,
wherein the second header is used in demodulating the second data, and
wherein the first data is different from the second data and the first header is different from the second header.
4. An information communication apparatus, comprising:
a determiner that determines a pattern of a change in luminance by modulating a signal to be transmitted; and
an outputter that outputs the determined pattern to a light emitter that changes in luminance according to the determined pattern,
wherein the signal includes a first data, a first header of the first data, second data, and a second header of the second data, and
wherein, in the determining, the pattern of the change in luminance is determined according to in an order of (i) the first data, (ii) the first header, (iii) the first data, (iv) the second data, (v) the second header, and (vi) the second data.
5. The information communication apparatus according to claim 4 , further comprising:
the light emitter changing in luminance according to the determined pattern.
6. A non-transitory recording medium having a computer program stored thereon that when executed by a processor causing the processor to perform operations, comprising:
determining a pattern of a change in luminance by modulating a signal to be transmitted; and
outputting the determined pattern to a light emitter that changes in luminance according to the determined pattern,
wherein the signal includes a first data, a first header of the first data, second data, and a second header of the second data, and
wherein, in the determining, the pattern of the change in luminance is determined according to in an order of (i) the first data, (ii) the first header, (iii) the first data, (iv) the second data, (v) the second header, and (vi) the second data.
