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 by sequentially starting exposure of each of the exposure lines of the image sensor at different times. Second image data is obtained by image capture with a second exposure time in the visible light communication mode. The information is obtained by demodulating data specified by a direction in a pattern of a bright line corresponding to the exposure lines, the second exposure time being shorter than the first exposure time. The second image data is obtained by capturing light emitted from the subject and spread by an optical system.

Abstract: A display method includes capturing, by an imaging sensor, a still image lit up by a transmitter that transmits a signal by luminance change of light as a subject to obtain a first captured image with a first exposure time. The still image is captured to obtain a second captured image with a second exposure time which is longer than the first exposure time. The display method further includes decoding the signal form the first captured image, and determining whether identification information included in each of a plurality of sets is identical to the decoded signal. Further, the method also includes reading the video included in each of the sets with the identification information identical to the decoded signal, and superimposing the video on a target region corresponding to the subject in the second captured image for display on a display.
