VISIBLE-LIGHT-COMMUNICATION-SIGNAL DISPLAY METHOD AND DISPLAY DEVICE

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).
