PROBLEM TO BE SOLVED: To provide an information communication method that enables communications with various equipment.SOLUTION: An information communication method comprises an exposure time setting step SA11 for setting an exposure time to 1/2000 second or less so that stripe-like bright lines parallel to exposure lines contained in an image sensor occur in an image obtained by imaging a subject with the image sensor according to brightness variation of the subject, an imaging step SA12 for successively starting exposure at different timings with respect to each of the plural exposure lines contained in the image sensor, thereby achieving an image containing the stripe-like bright lines parallel to the exposure lines, and an information achieving step SA13 for demodulating data according to light-dark variation appearing in the vertical direction to the exposure lines out of a pattern of the bright lines contained in the achieved image, thereby achieving information.SELECTED DRAWING: Figure 8 |
