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.

Claims

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;

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 having a stripe pattern configured with a different minimum pitch from the stripe pattern of the first visible light communication image.

2. A video display apparatus, on a per frame basis, an image included in a video signal, the video display apparatus including a processor, the processor executes operations 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;

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 having a stripe pattern configured with a different minimum pitch from the stripe pattern of the first visible light communication image.

3. 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;

switching a direction of the stripe pattern for the first visible light communication image to a different direction and generating a second visible light communication image; 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 direction by changing a spatial orientation of the stripe pattern from the stripe pattern of the first visible light communication image.

4. A video display apparatus, on a per frame basis, an image included in a video signal, the video display apparatus including a processor, the processor executes operations 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;

switching a direction of the stripe pattern for the first visible light communication image to a different direction and generating a second visible light communication image; 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 direction by changing a spatial orientation of the stripe pattern from the stripe pattern of the first visible light communication image.
