DISPLAY METHOD AND DISPLAY DEVICE

摘要

A display method for appropriately transmitting a visible light communication signal includes: a step of coding a visible light communication signal to generate an image having a striped pattern for visible light communication as a first visible light communication image; a step of displaying the image included in the video signal, in a predetermined frame; and a step of displaying a low-luminance image in the predetermined frame, and sequentially displaying the first visible light communication image, the low-luminance image being an identification image and having uniform luminance lower than average luminance of the image which is to be displayed, wherein in the step, after the image included in the video signal is displayed in the predetermined frame, each of the first identification image and the first visible light communication image is displayed in a same frame as the predetermined frame, for a period shorter than the predetermined frame.

主权项

1. A display method for displaying an image included in a video signal on a per frame basis, the display method comprising:
a visible light communication image generating step of coding a visible light communication signal to generate an image having a striped pattern for visible light communication as a first visible light communication image; a frame dividing step of dividing a frame in which an image included in the video signal is displayed into a plurality of subframes; a first display step of displaying the image included in the video signal, in a first subframe among the plurality of subframes; and a second display step of displaying a low-luminance image in a second subframe among the plurality of subframes, and displaying the first visible light communication image in a third subframe among the plurality of subframes, the low-luminance image being an identification image and having uniform luminance lower than average luminance of the image which is to be displayed, wherein in the second display step, after the image included in the video signal is displayed in the first subframe, each of the identification image and the first visible light communication image is displayed for a period shorter than time in which one frame is displayed.
