    摘要： A video display method which allows a visible light communication signal to be appropriately transmitted includes: generating an image having a stripe pattern as a visible light communication image (SL21) ; calculating average luminance of the visible light communication image (SL22); generating a visible light superimposition image by superimposing the visible light communication image only on, among one or more sub-images included in an image of a video signal that is displayed in the frame, a sub-image that is displayed in a specific sub-frame that is, among one or more sub-frames in each of which a corresponding one of the one or more sub-images is displayed, a sub-frame for representing the average luminance calculated (SL23); and displaying the visible light superimposition image in the specific sub-frame (SL24).

    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).
