Embodiment Construction

[0079] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0080] At present, the simplest visible light communication is to use the form of OOK (On-Off Keying) to make the backlight of the LCD display blink brightly and darkly to represent the code stream of "01010110...", and then obtain black and white stripes after taking pictures, and then decode the black and white stripes to obtain the original information. However, in existing visible light com...

Abstract

The invention relates to a display method and device, a visible light communication transmission method and device, a display device, and a computer-readable storage medium. A display method includes: acquiring an image frame to be displayed and its corresponding binary code stream; adjusting the gray scale of corresponding pixels in the image frame to be displayed based on the grayscale adjustment information group corresponding to each symbol in the binary code stream Step value, sequentially obtain the first image frame and the second image frame; display the first image frame and the second image frame. In this embodiment, the gray scale difference between two image frames will be larger, so as to facilitate terminal identification. In addition, this embodiment can avoid the gray scale distortion of the image and ensure the viewing effect.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a display method and device, a visible light communication transmission method and device, and a computer-readable storage medium. Background technique [0002] Visible light communication technology refers to the use of light in the visible light band as an information carrier, without the need for transmission media such as optical fibers, and directly transmits optical signals in the air. It can cover the range reached by light, so it has broad development prospects. Contents of the invention [0003] The present invention provides a display method and device, a visible light communication transmission method and device, and a computer-readable storage medium to solve the problem that signal transmission through OOK modulation is limited by a transmission mechanism and the rate is very low. [0004] According to a first aspect of an embodiment of the pre...
