Visible light communication signal display method and apparatus

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; 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; 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.

1. 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, the visible light communication signal display method comprising:
encoding at least part of the visible light communication signals to generate an encoded image; generating a plurality of sub-images which correspond to respective partial images obtained by spatially dividing the encoded image and each of which (i) includes a corresponding one of the partial images and (ii) except for the corresponding one of the partial images, is an image having a substantially uniform luminance value lower than or equal to a predetermined luminance value; 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, wherein in the encoding, a pattern that corresponds to the at least part of the visible light communication signals is selected from a plurality of the patterns for displaying a timing of each the sub-images to encode the at least part of the visible light communication signals into the pattern.
