Abstract: A video display method is provided that displays, on a per frame basis, an image included in a video signal. The method includes 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, and displaying, in a predetermined frame, the image included in the video signal. The method also includes switching a pitch of the first visible light communication image to a different pitch, and generating a second visible light communication image. The method further includes displaying the second visible light communication image that has a stripe pattern configured with a different minimum pitch, which is different in resolution from the stripe pattern of the first visible light communication image.
