Abstract: In one embodiment, such a method may include receiving a visible light signal by a sensor of a terminal device from a transmitter which transmits the visible light signal by a light source changing in luminance. The terminal device may transmit a request signal for requesting content associated with the visible light signal, from the terminal device to a server, and receive a content from the server. The content may include time points and data to be reproduced at the time points. Thereafter the terminal device may reproduce data included in the content and corresponding to a time point of a clock included in the terminal device.

Abstract: A video display method is provided that displays, on a per frame basis, an image included in a video signal. The method includes generating a first visible light communication image by encoding a visible light communication signal, the first visible light communication image being an image having a stripe pattern for visible light communication, and displaying, in a predetermined frame, the image included in the video signal. The method also includes switching a pitch of the first visible light communication image to a different pitch, and generating a second visible light communication image. The method further includes displaying the second visible light communication image that has a stripe pattern configured with a different minimum pitch, which is different in resolution from the stripe pattern of the first visible light communication image.

Abstract: An information communication method for obtaining information from a subject includes transmitting position information indicating a position of an image sensor used to capture the subject, and receiving an ID list that is associated with the position indicated by the position information. The method also includes setting an exposure time of the image sensor so that a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject. The method further includes obtaining a bright line image including the bright line by capturing the subject that changes in luminance by the image sensor with the set exposure time, obtaining the information by demodulating data specified by a pattern of the bright line included in the obtained bright line image, and searching the ID list for identification information.

Abstract: A receiving method includes: setting a first exposure time for at least one exposure line of exposure lines in an image sensor, setting a second exposure time for a remainder of the exposure lines in the image sensor, and causing the image sensor to capture an image of a light transmitter, to obtain a normal image from the at least one exposure line with the first exposure time, and to obtain a bright line image from the remainder of the exposure lines with the second exposure time. The second exposure time is shorter than the first exposure time. The bright line image includes a plurality of bright lines, each of which corresponds to a different one of the remainder of the exposure lines in the image sensor. Information is obtained by decoding a pattern of the plurality of the bright lines included in the obtained bright line image.

Abstract: A display method is provided that includes displaying an image included in a video signal on a per frame basis, and representing a tone level of luminance of the image by controlling a light emission period in a frame. The method also includes specifying a light emission period in which light emission is performed for greater than or equal to a time required for transmitting a visible light communication signal, and transmitting the visible light communication signal by superimposing the visible light communication signal onto a portion of the video signal corresponding to the specified light emission period. The method further includes in a case where the specified light emission period is greater than or equal to a time required for transmitting the visible light communication signal, the visible light communication signal is transmitted by luminance changing of the light source in the specified light emission period.

Abstract: A system with which any abnormality can easily be found is provided. A system includes: a first modulator that generates a control signal and modulates an input signal in accordance with the generated control signal, to control luminance of a first light source that emits light according to the modulated input signal, the first modulator outputting the control signal; and a second modulator that acquires a control signal output from the first modulator and modulates an input signal in accordance with the control signal, to control luminance of a second light source that emits light according to the modulated input signal. The first modulator generates, as an extinguishing signal, the control signal for extinguishing the first light source by an extinguishing period. After a lapse of the extinguishing period, the first modulator generates, as a light ID signal, the control signal for transmitting a visible light signal by luminance variations of the first light source.
