[0070] To enable those skilled in the art to better understand the technical solutions of this disclosure, the display control method, display control device, display equipment, and computer-readable medium provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0071] Exemplary embodiments will be described more fully below with reference to the accompanying drawings; however, these exemplary embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein.

[0073] It will be understood that while the terms first, second, etc., may be used herein to describe various elements, these elements should not be limited to these terms. These terms are used only to distinguish one element from another. Therefore, without departing from the teachings of this disclosure, the first element, first component, or first module discussed below may be referred to as a second element, second component, or second module.

[0075] Figure 1 This is a flowchart illustrating a display control method provided in an embodiment of this disclosure. Figure 1 As shown, the method includes:

[0076] Step S1: In response to the multi-channel display control command, the source video stream of the display panel is split into multiple identical sub-video streams.

[0077] In this embodiment, the same sub-video streams not only have the same data content, but are also time-synchronized; in some embodiments, the sub-video stream is a video stream with a different data format and / or resolution than the source video stream, but with the same perceptible video content; in some embodiments, the source video stream is input to multiple parallel video interfaces for multi-path expansion to achieve de-pathing processing; and in some embodiments, to cooperate with de-pathing processing, storage control logic for each sub-video stream is configured, and a buffer is set.

[0078] Step S2: For each sub-video stream, obtain the processing parameters corresponding to the sub-video stream, and process the sub-video stream according to the processing parameters.

[0079] In this process, video image processing is performed on the sub-video streams according to the processing parameters. This process corresponds to the processing process that can be perceived by the human eye, such as changing the sub-video streams in terms of color and brightness.

[0080] In some embodiments, pre-stored preset processing parameters are obtained, or in some embodiments, processing parameters input by the system in real time are obtained.

[0081] In some embodiments, the processing parameters include at least one of the following: color gamut parameters, brightness parameters, color temperature parameters, and sharpness parameters.

[0082] In some embodiments, the processing parameters corresponding to each sub-video stream are different. For example, for one sub-video stream, its color gamut parameter is adjusted, while for another sub-video stream, its brightness parameter is adjusted. Thus, different video image processing operations can be performed on multiple sub-video streams with the same content at the same time, or the same type of video image processing operations can be performed on multiple sub-video streams with different parameter configurations at the same time.

[0083] Step S3: Tile and merge the processed sub-video streams to obtain the output video stream, and output the output video stream to the display panel for display.

[0084] The process of tiling and merging the processed sub-video streams corresponds to splicing the processed sub-video streams together to make the resulting output video stream suitable for the display panel. It does not change the video content of each sub-video stream, but only splices the processed sub-video streams into a complete output video stream, so that the processed sub-video streams can be displayed on the same display device.

[0085] This disclosure provides a display control method that can be used to split a source video stream to obtain multiple identical sub-video streams. Each sub-video stream is processed based on different processing parameters, and the processed sub-video streams are tiled and merged. This allows multiple video processing operations to be performed on the same source video stream simultaneously, and the results of each video processing operation can be displayed on the same screen. This improves the flexibility of video image processing, and the results of multiple video processing operations can be monitored simultaneously using a single display device.

[0086] Figure 2 A flowchart illustrating another display control method provided in an embodiment of this disclosure. (See attached flowchart.) Figure 2 As shown, this method is based on Figure 1 A specific alternative implementation of the method shown is provided. Specifically, the method includes not only steps S1 to S3, but also step S01 preceding step S1. Step S01 will be described in detail below.

[0087] Step S01: Transform the source video stream according to the display parameters of the display panel.

[0088] In step S01, after completing the transformation processing of the source video stream, step S1 is executed to perform split processing on the source video stream of the display panel; wherein, the transformation processing corresponds to the preprocessing process of the source video stream so that the preprocessed source video stream meets the display requirements of the display panel, which may specifically include format conversion and resolution conversion.

[0089] The display parameters include at least one of the following: timing parameters, color parameters, resolution parameters, and frame rate parameters. Color parameters correspond to the adapted color space, such as RGB (Red, Green, Blue) color space or YUV (Luminosity, Chromaticity, and Visibility) color space. Resolution parameters correspond to Full High Definition (FHD), 4K, 8K, etc. Frame rate parameters can be 50Hz, 60Hz, 120Hz, etc. For each of the above types of display parameters, the source video stream is transformed through processing including: timing synchronization, color space transformation, upsampling or downsampling, and frame rate transformation.

[0090] In some embodiments, the display parameters also include splicing method parameters, also known as arrangement method parameters, such as the Two Sample Interleave (2SI) method and the Square Division (SQD) method for 4K image video streams; corresponding to the type of display parameter, the source video stream is transformed, including splicing method transformation processing.

[0091] In some embodiments, the subsequent module devices corresponding to the subsequent steps include a fixed algorithm module, which has strict requirements on the timing and data format of the input signal. For example, each processing channel of the subsequent module that processes multiple video streams in parallel is adapted to process RGB444 / FHD / 60hz / SQD format videos. In this case, step S01 needs to be executed to perform transformation processing to ensure that the video format and timing meet the input requirements of the subsequent device modules.

[0092] Figure 3 This is a flowchart illustrating a specific implementation of step S1 in this disclosure. Specifically, the multi-channel display control command can be input by the user, and the multi-channel display control command may include the number of channels; such as... Figure 3 As shown, step S1, which is a step of splitting the source video stream of the display panel to obtain multiple identical sub-video streams in response to a multi-channel display control command, includes step S101.

[0093] Step S101: Perform split processing on the source video stream according to the number of splits and the resolution of the display panel.

[0094] In some embodiments, the resolution of each sub-data stream is determined based on the number of splits and the resolution of the display panel, such as by determining the resolution of each sub-data stream based on the ratio of the display panel resolution to the number of splits. The source video stream is then processed to obtain multiple sub-data streams, where the number of sub-data streams is the number of splits and the resolution is the previously determined resolution. Alternatively, in some embodiments, a minimum resolution for the sub-data streams or a maximum number of sub-data streams is pre-configured. The resolution of each sub-data stream and the actual number of splits are determined based on the number of splits and the resolution of the display panel, thereby processing the source video stream to obtain multiple sub-data streams.

[0095] Figure 4 This is a flowchart illustrating a specific implementation method of step S3 in this disclosure. Figure 4 As shown, step S3, which involves tiling and merging the processed sub-video streams to obtain the output video stream, includes step S301.

[0096] Step S301: Generate timing control signals according to the timing parameters corresponding to the display panel, adjust the timing of each processed sub-video stream according to the timing control signals, and tile and merge the timing-adjusted sub-video streams.

[0097] Since the resolution of the sub-video stream may not correspond to the display parameters of the display panel, and its timing may also not correspond to the timing parameters of the display panel, the timing of each sub-video stream is adjusted so that each sub-video stream can be displayed normally after tiling and merging.

[0098] Figure 5 This is a flowchart illustrating another specific implementation of step S3 in this disclosure. Figure 5 As shown, step S3, which involves tiling and merging the processed sub-video streams to obtain the output video stream, includes steps S31 and S32.

[0099] Step S31: Determine the arrangement method based on the number of sub-video streams and the resolution of the display panel, and determine the first display area corresponding to each sub-video stream.

[0100] This involves determining the arrangement method corresponding to the tiling and merging, and determining the pixel display position corresponding to each sub-video stream, which is the first display area.

[0101] Step S32: According to the arrangement and the first display area corresponding to each sub-video stream, the processed sub-video streams are tiled and merged.

[0102] Figure 6 This is a schematic diagram illustrating one arrangement in step S3 of an embodiment of this disclosure. For example... Figure 6As shown, it exemplifies an arrangement for two and four sub-video streams respectively. In (a), it exemplifies an arrangement for two sub-video streams, which is a tiled arrangement in the column direction, where V1 and V2 represent the first display areas for the two sub-video streams respectively. In (b), it exemplifies an arrangement for four sub-video streams, which is a tiled arrangement in the row and column directions, where V3, V4, V5, and V6 represent the first display areas for the four sub-video streams respectively. It should be noted that in some embodiments, the first display area can be a regular shape, such as a rectangle, triangle, or circle, and can be tiled in the column, row, or diagonal directions. Alternatively, in some embodiments, the first display area can be an irregular shape depending on actual needs. In some embodiments, the first display area for each sub-video stream is the same size, or in some embodiments, the first display area for each sub-video stream can be different, allowing the selection of the primary, interesting sub-video stream to occupy a larger area in its first display area.

[0103] Figure 7 A flowchart illustrating another display control method provided in this disclosure embodiment. Specifically, the method is based on... Figure 1 and Figure 5 A specific alternative implementation of the method shown is provided. For example... Figure 6 As shown, the method includes not only steps S1 to S32, but also step S201 before step S2. In some embodiments, for step S3, step S31 includes step S311, and step S32 includes step S321. The following describes steps S201, S311, and S321 in detail only.

[0104] Specifically, for each sub-video stream, before performing step S2 to obtain the processing parameters corresponding to the sub-video stream and process the sub-video stream according to the processing parameters, the method further includes step S201.

[0105] Step S201: For each sub-video stream, perform video analysis on the sub-video stream according to the preset first analysis item;

[0106] Before performing video image processing on each sub-video stream, it can be analyzed to determine its various video image parameters for accurate subsequent processing. The first analysis item includes at least one of the following: color waveform analysis, video brightness waveform analysis, video color histogram analysis, video brightness histogram analysis, video color vector analysis, video brightness pseudo-color marking, video focus quality analysis, video brightness area marking, and video pixel visualization marking.

[0107] In some embodiments, such as Figure 7As shown, in step S201, for each sub-video stream, based on video analysis of the sub-video stream according to the preset first analysis item: step S31, determining the arrangement method and determining the first display area corresponding to each sub-video stream according to the number of sub-video streams and the resolution of the display panel, including step S311; step S32, tiling and merging the processed sub-video streams according to the arrangement method and the first display area corresponding to each sub-video stream, including step S321.

[0108] Step S311: Based on the number of sub-video streams and the resolution of the display panel, determine the arrangement method, determine the first display area corresponding to each sub-video stream, and determine the second display area corresponding to the video analysis result image.

[0109] The first display area is used to display the sub-video streams; the second display area, also known as the reserved area, is used to display the video analysis result image corresponding to each sub-video stream. This video analysis result image is generated based on the video analysis results and can represent various video image parameters of the sub-video stream. Setting up the second display area can improve the perceptibility of video image processing operations, allowing users to intuitively determine the video image processing effect and the degree of change. In addition, the setting of the second display area can also avoid excessive transformation of the resolution of the sub-video streams and prevent the display image from being compressed or stretched.

[0110] Step 321: Based on the arrangement, the first display area corresponding to each sub-video stream, and the second display area corresponding to the video analysis result image, the processed sub-video streams and video analysis result images are tiled and merged.

[0111] Figure 8 This is a schematic diagram illustrating another arrangement in step S3 of an embodiment of this disclosure. For example... Figure 8 As shown, it exemplifies an arrangement for two and three sub-video streams respectively. Specifically, in (c), it exemplifies an arrangement for two sub-video streams, which is a tiling arrangement in the row direction. V11 and V21 represent the first display areas corresponding to the two sub-video streams, and Blank1 and Blank2 represent two second display areas, which can be used to display the video analysis result image corresponding to at least one of the two sub-video streams. In (d), it exemplifies an arrangement for three sub-video streams, where V7, V8, and V9 represent the first display areas corresponding to the three sub-video streams, and Blank3 and Blank4 represent two second display areas, which can be used to display the video analysis result image corresponding to at least one of the three sub-video streams.

[0112] Figure 9A flowchart illustrating another display control method provided in an embodiment of this disclosure. Specifically, the method is based on... Figure 7 A specific alternative implementation of the method shown is provided. For example... Figure 9 As shown, the method includes not only steps S1 to S321, but also steps S202 and S203 before step S3. The following describes steps S202 and S203 in detail only.

[0113] Prior to step S3, which involves tiling and merging the processed sub-video streams to obtain the output video stream, the method further includes:

[0114] Step S202: According to the preset second analysis item, perform pairwise difference analysis on at least two of the processed sub-video streams.

[0115] The second analysis item includes at least one of pixel value difference analysis, pixel grayscale value difference analysis, and pixel gradient feature value difference analysis. Corresponding to each of the above second analysis items, when performing difference analysis, it is performed on two pixels in the same time sequence, the same frame, and at the same pixel position in the two sub-video streams. Specifically, when performing pixel value difference analysis, the pixel values ​​of the two pixels can be compared to obtain the difference analysis result; when performing pixel grayscale value difference analysis, the grayscale values ​​of the two pixels can be compared to obtain the difference analysis result; when performing pixel gradient feature value difference analysis, the gradient feature values ​​of the two pixels within the same frame can be compared to obtain the difference analysis result.

[0116] In some embodiments, the second analysis item may further include pixel subpixel component difference analysis; specifically, when performing pixel subpixel component difference analysis, the values ​​of the subpixel components of two pixels can be compared to obtain the difference analysis result, such as for a sub-video stream based on red-green-blue color space, comparing any one of the red component, green component and blue component of two pixels to obtain the difference analysis result.

[0117] Step S203: Based on the difference analysis results, the pixels that meet the preset marking conditions are marked through the on-screen menu adjustment (On Screen Display, OSD).

[0118] The marking condition is that the difference value between the two pixels undergoing difference analysis is greater than a preset difference threshold. When marking pixels, both pixels undergoing difference analysis can be marked simultaneously, or only one of them can be marked. In some embodiments, the pixel can be marked by covering it with a dot of a specific color, or by selecting it with a frame of a specific color. Such methods can include red dots, red frames, etc.

[0119] It should be noted that the above-mentioned combination of video analysis and difference analysis is only a specific optional implementation scheme provided by the embodiments of this disclosure, and it will not affect the protection scope of the technical solution of this disclosure. The two implementations independently are equally applicable to the technical solution of this disclosure.

[0120] This disclosure provides a display control method that can be used to perform video analysis on sub-video streams before video image processing, enabling users to clearly monitor various image parameters; and to perform pairwise difference analysis on sub-video streams after video image processing, enabling users to accurately judge the video image processing effect and quality by combining the actual processed image and the perceptible difference; if the above two are implemented in combination, the perceptibility of the difference between different video image processing operations is improved, while allowing users to intuitively monitor specific image parameters.
