摘要： A video display method in which a visible light communication signal can be appropriately transmitted includes: generating a first visible light communication image that is an image having a stripe pattern for visible light communication, by encoding the visible light communication signal (SL11); displaying, in a predetermined frame, an image included in the video signal (SL12); and displaying, in the predetermined frame, the first visible light communication image sequentially thereafter an identification image that is an image having luminance uniformly lower than average luminance of the image that is displayed (SL13).

摘要： A visible light communication signal display method of displaying (i) an image represented by video signals and (ii) an image obtained by encoding visible light communication signals includes: encoding at least part of the visible light communication signals to generate an encoded image (S101); generating a plurality of sub-images which correspond to respective partial images obtained by dividing the encoded image and each of which (i) includes a corresponding one of the partial images and (ii) except for the corresponding partial image, is an image having a substantially uniform luminance value lower than or equal to a predetermined luminance value (S102); and displaying, in a video display period, the image represented by the video signals, and displaying the sub-images in time series in a communication period different from the video display period (S103).

摘要： An information communication method that enables communication between various devices includes: determining a pattern of the change in luminance by modulating the signal to be transmitted (SK31); and transmitting the signal by a light emitter changing in luminance according to the determined pattern (SK32), wherein 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, and in the determining (SK31), the pattern of the change in luminance is determined so that a luminance change position in the duration is different for each of different signals to be transmitted, the luminance change position being a position at which the luminance rises or a position at which the luminance falls.

摘要： An information communication method that enables communication between various devices includes: setting an exposure time of an image sensor (SK21); obtaining a bright line image including a bright line, by capturing a subject that changes in luminance by the image sensor with the set exposure time (SK22); setting a longer exposure time than the exposure time (SK23); obtaining a normal captured image by image capture by the image sensor with the longer exposure time (SK24); generating a synthetic image by specifying, in the normal captured image, a part that corresponds to the bright line included in the bright line image and superimposing a signal object on the normal captured image, the signal object being an image indicating the part (SK25); displaying the synthetic image (SK26); and obtaining information by demodulating data specified by a pattern of the bright line included in the obtained bright line image (SK27).
