Embodiment Construction

[0058] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0059] First, some terms involved in this application are introduced.

[0060] High Dynamic Range (HDR) image synthesis algorithm is a scene image synthesis algorithm that uses high-speed computer computing to produce high-quality realistic effects. The dynamic range refers to the ratio of the maximum value to the minimum value of the brightness value of the image. The larger the dynamic range, the more scene details the image displays and the more realistic the visual effect. Generally, traditional images use one byte, that is, 8 bits, to store a pixel value, so the brightness level of ordinary images is only 256 levels, which cannot meet the high requirements for scene details in many occa...

Abstract

The invention relates to a synchronous display control method and device for multiple display screens and a storage medium, and belongs to the technical field of computers. The method includes the steps: receiving the kth frame of video source information; reading and processing related data of the kth frame of video source information when a processing moment is reached to obtain initial processing parameters, wherein the processing moment is used for controlling n stages of transmitters to simultaneously read related data of the same frame of video source information; synchronizing the processing parameters of the n stages of transmitters based on the initial processing parameters to obtain synchronous processing parameters; and sending the video information processed according to the synchronous processing parameters to a display screen connected with the ith-level transmitter. Since the related data of the kth frame of video source information is read for processing only when the processing moment is reached, it can be ensured that different transmitters read the related data of the same frame of video source information at the same moment, thereby eliminating the time delay ofstarting to process video sources by different transmitters, and further eliminating the problem of asynchronous display of a display screen.

Description

technical field [0001] The application relates to a synchronous display control method, device and storage medium of multiple display screens, belonging to the technical field of computers. Background technique [0002] Existing display screens usually use a combination of multiple display screens, one or more display screens are connected to a transmitter, and the transmitter is connected to a video source. [0003] In order to ensure that the display screens connected to different transmitters are synchronized, the video source is usually synchronized. [0004] However, there are various image algorithms running in the transmitter, such as HDR image synthesis algorithm, noise reduction algorithm, etc. At this time, the transmitter will perform secondary processing on the synchronized video source, and the time between different transmitters to start processing The delay may be different, which will cause the displays connected to different transmitters to appear out of sy...
