Embodiment Construction

[0058] The specific implementations of the present application will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are used to illustrate the present application, but are not intended 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 operations to produce high-quality realistic effects, and is an image mapping technology that expresses a range of brightness that exceeds the display's ability to express. 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 details of the scene displayed by the image, and the more realistic the visual effect. The general traditional image uses one byte, that is, 8 bits of space...

Abstract

The present application relates to a synchronous display control method, device and storage medium for multiple display screens, which belong to the field of computer technology. The method includes: receiving the video source information of the kth frame; reading the video source information of the kth frame when the processing time is reached Relevant data is processed to obtain initial processing parameters; the processing time is used to control n-level transmitters to simultaneously read related data of the same frame of video source information; based on the initial processing parameters, the processing parameters of n-level transmitters are synchronized to obtain synchronous processing parameter; send the video information processed according to the synchronization processing parameters to the display screen connected to the i-th level transmitter. Since the relevant data of the kth frame of video source information is read for processing when the processing time is reached, it can be ensured that different transmitters read the relevant data of the same frame of video source information at the same time, thereby eliminating the need for different transmitters to start processing video The delay of the source, thereby eliminating the problem of out-of-sync display on the display.

Description

technical field [0001] The present application relates to a synchronous display control method, device and storage medium for multiple display screens, belonging to the technical field of computers. Background technique [0002] Existing displays typically use a combination of multiple displays, with one or more displays connected to a transmitter, which is connected to a video source. [0003] In order to ensure the display synchronization of the display screens connected to different transmitters, the video sources are usually synchronized. [0004] However, there are a variety of 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 when processing starts between different transmitters The delays may vary, causing the displays connected to different transmitters to appear out of sync.
