Video display method using visible light communication image including stripe patterns having different pitches

摘要

A video display method in which a visible light communication signal can be appropriately transmitted includes: Step SL 11 of 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; Step SL12 of displaying, in a predetermined frame, an image included in the video signal; and Step SL13 of 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.

1. A video display method of displaying, on a per frame basis, an image included in a video signal, the video display method comprising:
generating a first visible light communication image by encoding a visible light communication signal, the first visible light communication image being an image having a stripe pattern for visible light communication; displaying, in a predetermined frame, the image included in the video signal; displaying, in the predetermined frame, the first visible light communication image sequentially after an identification image that is an image having luminance uniformly lower than average luminance of the image that is displayed, switching a pitch of the first visible light communication image to a different pitch and generating a second visible light communication image, wherein pitch is the interval between stripes in the stripe pattern; and displaying the second visible light communication image after displaying the first visible light communication image, the second visible light communication image being an image having a stripe pattern for visible light communication, wherein in the displaying of the second visible light communication image, the image has a stripe pattern configured with a different minimum pitch from the stripe pattern of the first visible light communication image.
