    Abstract: An information communication method of transmitting a signal is provided that uses a change in luminance. The method includes 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. 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. The determining a pattern of change in luminance includes dividing the predetermined duration into four duration units, so that one of two different luminance value occurs in one duration unit of the four duration units and the other luminance value of the two different luminance value occurs in three duration units of the four duration units, the three duration units are other than the one duration unit.

    Abstract: An apparatus includes a processor and a recording medium having a program, the program causing the processor to execute operations. The operations include a normal mode and a visible light communication mode, wherein the normal mode and the visible light communication mode are switchable. In the normal mode, first image data is obtained by image capture with a first exposure time by sequentially starting exposure for a plurality of exposure lines in an image sensor each at a different time and each of the plurality of exposure lines partially overlaps in exposure time an adjacent exposure line. The visible light communication mode includes (i) setting a second exposure time of the image sensor, (ii) obtaining a bright line image including the plurality of bright lines, and (iii) obtaining information by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image.

    Abstract: An information communication method selects between a visible light communication mode, in which information is obtained from a subject using an image sensor having a plurality of exposure lines, and a normal imaging mode. The information communication method includes obtaining first image data by image capture with a first exposure time in the normal imaging mode and obtaining second image data by image capture with a second exposure time, shorter than the first exposure time, in the visible light communication mode. When the second image data is obtained by capturing a plurality of subjects reflected on a reflection surface, the information is obtained by separating a bright line corresponding to each subject from bright lines included in the second image data according to a strength of the bright line and demodulating, for each subject, the data specified by the pattern of the bright line.
