Abstract:
A display method capable of reducing the probability of communication error without causing significant deterioration of picture quality includes: specifying (SL21), as a specified light emission period, a light emission period in which light emission is performed for greater than or equal to a time required for transmitting a block included in a visible light communication signal, out of one or more light emission periods in which light emission is performed for displaying an image included in a video signal; and transmitting (SL22) the block of the visible light communication signal by luminance changing in the specified light emission period.
Abstract:
An information communication method that enables communication between various devices includes: (SK51) transmitting position information indicating a position of an image sensor; (SK52) receiving an ID list; (SK53) setting an exposure time of the image sensor; (SK54) obtaining a bright line image including a bright line, by capturing a subject by the image sensor; (SK55) obtaining information by demodulating data specified by a pattern of the bright line included in the obtained bright line image; and (SK56) searching the ID list for identification information that includes the obtained information.
Abstract:
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).

Abstract:
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).
