Description
Technical Field
The invention relates to the technical field of image processing, in particular to a spliced screen jelly effect processing device, a method and a controller.
Background
In the application of the existing spliced screen composed of a plurality of display screens, a splicing processor is required to synchronously process signals sent to each screen in order to enable each display screen to play the same frame of picture at the same time. If the image is not processed or is not processed properly, the situation that the image displayed by the spliced large screen is misplaced and torn can be caused
In the video signal, the field sync signal is a start signal for starting scanning display of one frame image. The line synchronizing signal is a start signal for starting scanning display of one line of a frame image. At present, the scanning mode of the conventional liquid crystal display screen is mostly progressive scanning. The working principle is as follows: when the start signal of one frame of image is generated, the pixels of the first row are displayed first, and after all the pixels of the first row are displayed, the pixels of the second row are displayed next. In this manner, one line is displayed one line until all pixels of the last line are displayed. In such a scanning mode, the display of different pixels on the same row has a time difference, but human eyes and display pixels have certain afterglow effect, so that different pixels cannot be seen by people to be displayed in a time-sharing manner.
Chinese patent application publication No.: CN103065610A, which discloses a method and an apparatus for synchronously processing a spliced screen. The splicing screen is composed of M multiplied by N sub-screens, each frame image is divided into M multiplied by N sub-images, the M multiplied by N sub-images are correspondingly displayed by the M multiplied by N sub-screens one by one, and each sub-screen adopts a progressive scanning mode; for each frame of current image, scanning signals of M sub-images corresponding to the current image from top to bottom for M sub-screens in each column; and starting to scan the sub-image signal corresponding to the next sub-screen within a certain time range before and after the scanning completion time point of the sub-image signal corresponding to the previous sub-screen for any two up-and-down adjacent sub-screens in the column. Namely, chinese patent application publication No.: the technical scheme disclosed by CN103065610A is as follows: the field sync signals of the same line of the display screen are synchronized and the field sync signal of the second line of the display screen is one frame slower than the field sync signal of the first line of the display screen. The field sync signal of the third line of the display is two frames slower than the field sync signal of the second line of the display. And so on, the field sync signal of the nth row display is n-1 frames slower than the field sync signal of the first row display. So the Chinese patent application publication number: the technical solution disclosed in CN103065610A is not problematic when the number of lines of the tiled screen is small, and when the number of lines of the tiled screen is large, because the screens of adjacent lines have a time difference of one frame, the number of frames of the display difference between the first line and the last line will be large, resulting in an image display error and tearing. For example, in an 8 (row) × 7 (column) tiled display screen application, the field signals for 7 displays on the same row are synchronized. Whereas the field signal of the second line display is one frame slower than the field signal of the first line display, the field signal of the third line display is one frame slower than the field signal of the second line display, and so on, the field signal of the eighth line display is seven frames slower than the field signal of the first line. Thus, the conditions of dislocation, tearing and the like of the images displayed on the multi-screen spliced wall can be caused.

The first embodiment is as follows:
as shown in fig. 1-10, a spliced screen jelly effect processing device is provided, where the spliced screen is composed of a × B display screens and a × B display screen image processing mechanisms, where a and B are both natural numbers, the a × B display screen image processing mechanisms correspond to the a × B display screens one-to-one, and divide each frame image into a × B partial sub-images, where the a × B partial sub-images are displayed by the a × B display screens one-to-one, the display screen image processing mechanisms include an image receiving component, a refresh control component, an image output component, and a controller, and the image receiving component, the refresh control component, the image output component, and the display screens are all connected to the controller;

the refreshing control component is used for configuring the refreshing directions of the display screens, wherein the refreshing directions comprise from top to bottom and from bottom to top, and/or from left to right and from right to left, so that the refreshing directions of any two vertically adjacent display screens in the same column are different, and/or the refreshing directions of any two horizontally adjacent display screens in the same row are different; preferably, the refresh control assembly includes a first refresh control assembly and a second refresh control assembly, the first refresh control assembly and the second refresh control assembly are both connected to the controller, specifically, the first refresh control assembly is connected to the controller, the first refresh control assembly is configured to configure the refresh direction of the display screen to be from top to bottom and from bottom to top, so that the refresh direction of any two vertically adjacent display screens in the same row is different, and the second refresh control assembly is configured to configure the refresh direction of the display screen to be from left to right or from right to left, so that the refresh direction of any two horizontally adjacent display screens in the same row is different.
The image output component is used for acquiring the sub-image identified by the image receiving component and displaying the sub-image on the display screen according to the refreshing direction configured by the first refreshing control component.
In this embodiment, each frame of image to be displayed is divided into a × B partial sub-images corresponding to a × B display screens by image/video processing software/program, the sub-images to be displayed by the display screens corresponding to the image receiving assemblies are actively distributed to the image receiving assemblies through the background, or the image receiving assemblies actively identify and acquire the sub-images to be displayed by the corresponding display screens from the memory, and then the sub-images are sent to the image output assemblies, when the image receiving assemblies identify the sub-images to be displayed by the display screens, the first refresh control assemblies or the second refresh control assemblies start to configure the refresh direction of the display screens, in this embodiment, the refresh form of the display screens is progressive scanning or progressive scanning, if the refresh form of the display screens is progressive scanning, the first refresh control assemblies are selected to configure the refresh direction of the display screens, if the refresh mode of the display screen is line-by-line scanning, the second refresh control component is selected to configure the refresh direction of the display screen. When the refreshing mode of the display screen is progressive scanning, the refreshing direction of the display screen is configured by adopting the first refreshing control component, so that the refreshing directions of any two vertically adjacent display screens in the same column are different, wherein the refreshing direction is from top to bottom or from bottom to top. In the present embodiment, assuming that there are 1080 lines of image pixels to be displayed per display screen, the first line is represented as: row1, second Row is represented as: row2, and so on, line1080 as: row1080, therefore, when An is scanned from Row1080 to Row1 (from bottom to top, as shown in fig. 2), the scan of a (n +1) or a (n-1) adjacent to An up and down is scanned from Row1 to Row1080 (from top to bottom, as shown in fig. 1), where An is a display in a certain line of the tiled screen, a (n +1) is a display in a next line of the display in the certain line of the tiled screen, and a (n-1) is a display in a previous line of the display in the certain line of the tiled screen. In this embodiment, taking A3 × 3 tiled display as an example, after image signals are input, image receiving modules of 9 display screens all receive image signals at the same time, and after synchronization processing, transmit the image signals to an image output module, assuming that a1 is scanned from top to bottom (from Row1 to Row1080), as shown in fig. 1, a2 is scanned from bottom to bottom (from Row1080 to Row1), as shown in fig. 2, A3 is scanned from top to bottom (from Row1 to Row1080), as shown in fig. 1, where a1 is a first Row display screen, a2 is a second Row display screen, and A3 is a third Row display screen. Take the F3 image refresh process of the display screen of two rows a1 and a2 as an example. At time T1, the images displayed by a1 and a2 are the same frame image, i.e., F2 image (shown in fig. 3). Then, the refresh of the F3 image is started, and the image of a1 is a top-down refreshed F3 image, that is, the F3 image of a1 covers the F2 image line by line from top to bottom. The image of a2 is an image in which F3 is refreshed from bottom to top, that is, the F3 image of a2 covers the F2 image line by line from bottom to top. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 4). At time T3, the F3 images of A1 and A2 are both refreshed completely (as shown in FIG. 5). In the whole refreshing process of the F3 image, the F2 image is always displayed at the boundary of the A1 and the A2, so that the image is not misplaced or torn. Therefore, the scanning mode of A1 from top to bottom and A2 from bottom to top solves the jelly effect of the display screen of A1 and A2. Similarly, taking the F3 image refresh process of the display screen with two rows a2 and A3 as an example: at time T1, the images displayed by a1 and a2 are the same frame image, i.e., F2 image (shown in fig. 3). Then, the refresh of the F3 image is started, and the image of a2 is an image for refreshing F3 from bottom to top, that is, the F3 image of a2 is an image for covering F2 from bottom to top row by row. The image of A3 is a top-down refreshed F3 image, i.e., the F3 image of A3 covers the F2 image line by line from top to bottom. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 4). At time T3, the F3 images of A1 and A2 are both refreshed completely (as shown in FIG. 5). In the whole refreshing process of the F3 image, the F3 image is always displayed at the boundary of the A2 and the A3, so that the image is not misplaced or torn. Therefore, the scanning mode from bottom to top of A2 and from top to bottom of A3 also solves the jelly effect of the A2 and A3 screen displays.
In this embodiment, when the refresh mode of the display screen is column-by-column scanning, the refresh direction of the display screen is configured by using the second refresh control component, so that the refresh directions of any two left and right adjacent display screens in the same row are different, where the refresh direction is from left to right or from right to left. In this embodiment, assuming that there are 1080 columns of image pixels to be displayed per display screen, the first column is represented as: line1, second row is represented as: line2, and so on, Line1080 as: line1080, therefore, when the scan pattern of Bn is from Line1080 to Line1 (from right to left, as shown in FIG. 7), the scan pattern of B (n +1) or B (n-1) adjacent to Bn is from Line1 to Line1080 (from left to right, as shown in FIG. 6), where Bn is a column of display screens of the tiled screen, B (n +1) is a column of display screens connected to the right side of a column of display screens of the tiled screen, and B (n-1) is a column of display screens connected to the left side of a column of display screens of the tiled screen. In this embodiment, taking a3 × 3 tiled display as an example, after image signals are input, image receiving modules of 9 display screens all receive image signals at the same time, and after synchronization processing, transmit the image signals to an image output module, assuming that the scanning mode of B1 is from left to right (scanning from Line1 to Line1080), the scanning mode of B2 is from right to left (scanning from Line1080 to Line1), and the scanning mode of B3 is from left to right (scanning from Line1 to Line1080), where B1 is a first column display screen, B2 is a second column display screen, and B3 is a third column display screen. Take the F3 image refresh process of the display screens of the two columns B1 and B2 as an example. At the time T1, the images displayed by B1 and B2 are the same frame image, i.e., F2 image (shown in fig. 8). Then, the refresh of the F3 image is started, and the image of B1 is a top-down refreshed F3 image, that is, the F3 image of B1 overlaps the F2 image column by column from top to bottom. The image of B2 is an image that refreshes F3 from bottom to top, that is, the F3 image of B2 covers the F2 image column by column from bottom to top. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 9). At time T3, the F3 images of both B1 and B2 are refreshed (as shown in fig. 10). In the whole refreshing process of the F3 image, the F2 image is always displayed at the boundary of the B1 and the B2, so that the image can not be dislocated or torn. Therefore, the scanning mode of B1 from top to bottom and B2 from bottom to top solves the jelly effect of the display screens of B1 and B2. Similarly, taking the F3 image refresh process of the display screen of two columns B2 and B3 as an example: at the time T1, the images displayed by B1 and B2 are the same frame image, i.e., F2 image (shown in fig. 8). Then, the refresh of the F3 image is started, and the image of B2 is an image for refreshing F3 from bottom to top, that is, the F3 image of B2 is an image for covering F2 column by column from bottom to top. The image of B3 is a top-down refreshed F3 image, i.e., the F3 image of B3 overlays the F2 image column by column from top to bottom. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 9). At time T3, the F3 images of both B1 and B2 are refreshed (as shown in fig. 10). In the whole refreshing process of the F3 image, the F3 image is always displayed at the boundary of the B2 and the B3, so that the image is not misplaced or torn. Therefore, the scanning mode from bottom to top of B2 and from top to bottom of B3 also solves the jelly effect of the screen display of B2 and B3.

In this embodiment, taking fig. 3 as an example (a 3 × 3 tiled screen), each box in the figure represents one display screen, and 9 display screens are provided, and the image displayed by the 9 display screens is tiled to be F2, which represents the second frame image, and the image displayed by any one of the 9 display screens alone is a sub-image.

In the present embodiment, assuming that there are 1080 lines of image pixels to be displayed per display screen, the first line is represented as: row1, second Row is represented as: row2, and so on, line1080 as: row1080, therefore, when An is scanned from Row1080 to Row1 (from bottom to top, as shown in fig. 2), the scan of a (n +1) or a (n-1) vertically adjacent to An is scanned from Row1 to Row1080 (from top to bottom, as shown in fig. 1), where An is a display in a certain line of the tiled screen, a (n +1) is a display in a next line of the display in the certain line of the tiled screen, and a (n-1) is a display in a previous line of the display in the certain line of the tiled screen.
S3: and the image output component acquires the sub-image identified by the image receiving component and displays the sub-image on the display screen according to the refreshing direction configured by the first refreshing control component.
In this embodiment, taking A3 × 3 tiled display as an example, after image signals are input, image receiving modules of 9 display screens all receive image signals at the same time, and after synchronization processing, transmit the image signals to an image output module, assuming that a1 is scanned from top to bottom (from Row1 to Row1080), as shown in fig. 1, a2 is scanned from bottom to bottom (from Row1080 to Row1), as shown in fig. 2, A3 is scanned from top to bottom (from Row1 to Row1080), as shown in fig. 1, where a1 is a first Row display screen, a2 is a second Row display screen, and A3 is a third Row display screen. Take the F3 image refresh process of the display screen of two rows a1 and a2 as an example. At time T1, the images displayed by a1 and a2 are the same frame image, i.e., F2 image (shown in fig. 3). Then, the refresh of the F3 image is started, and the image of a1 is a top-down refreshed F3 image, that is, the F3 image of a1 covers the F2 image line by line from top to bottom. The image of a2 is an image in which F3 is refreshed from bottom to top, that is, the F3 image of a2 covers the F2 image line by line from bottom to top. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 4). At time T3, the F3 images of A1 and A2 are both refreshed completely (as shown in FIG. 5). In the whole refreshing process of the F3 image, the F2 image is always displayed at the boundary of the A1 and the A2, so that the image is not misplaced or torn. Therefore, the scanning mode of A1 from top to bottom and A2 from bottom to top solves the jelly effect of the display screen of A1 and A2. Similarly, taking the F3 image refresh process of the display screen with two rows a2 and A3 as an example: at time T1, the images displayed by a1 and a2 are the same frame image, i.e., F2 image (shown in fig. 3). Then, the refresh of the F3 image is started, and the image of a2 is an image for refreshing F3 from bottom to top, that is, the F3 image of a2 is an image for covering F2 from bottom to top row by row. The image of A3 is a top-down refreshed F3 image, i.e., the F3 image of A3 covers the F2 image line by line from top to bottom. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 4). At time T3, the F3 images of A1 and A2 are both refreshed completely (as shown in FIG. 5). In the whole refreshing process of the F3 image, the F3 image is always displayed at the boundary of the A2 and the A3, so that the image is not misplaced or torn. Therefore, the scanning mode from bottom to top of A2 and from top to bottom of A3 also solves the jelly effect of the A2 and A3 screen displays.
S2.3: configuring different refreshing directions of any two left and right adjacent display screens in the same row through a second refreshing control component, wherein the refreshing directions are from left to right or from right to left;
specifically, when the refresh mode of the display screen is row-by-row scanning, the refresh direction of the display screen is configured by the second refresh control component, so that the refresh directions of any two left and right adjacent display screens in the same row are different, wherein the refresh direction is from left to right or from right to left. In this embodiment, assuming that there are 1080 columns of image pixels to be displayed per display screen, the first column is represented as: line1, second row is represented as: line2, and so on, Line1080 as: line1080, therefore, when the scan pattern of Bn is from Line1080 to Line1 (from right to left, as shown in FIG. 7), the scan pattern of B (n +1) or B (n-1) adjacent to Bn is from Line1 to Line1080 (from left to right, as shown in FIG. 6), where Bn is a column of display screens of the tiled display, B (n +1) is a column of display screens connected to the right side of a column of display screens of the tiled display, and B (n-1) is a column of display screens connected to the left side of a column of display screens of the tiled display.
S3: and the image output component acquires the sub-image identified by the image receiving component, and displays the sub-image on the display screen according to the refreshing direction configured by the second refreshing control component.
In this embodiment, taking a3 × 3 tiled display as an example, after image signals are input, image receiving components of 9 display screens all receive image signals at the same time, and after synchronization processing, transmit the image signals to an image output component, assuming that the scanning mode of B1 is from left to right (scanning from Line1 to Line1080), as shown in fig. 6, the scanning mode of B2 is from right to left (scanning from Line1080 to Line1), as shown in fig. 7, the scanning mode of B3 is from left to right (scanning from Line1 to Line1080), as shown in fig. 6, where B1 is a first column display screen, B2 is a second column display screen, and B3 is a third column display screen. Take the F3 image refresh process of the display screens of the two columns B1 and B2 as an example. At the time T1, the images displayed by B1 and B2 are the same frame image, i.e., F2 image (shown in fig. 8). Then, the refresh of the F3 image is started, and the image of B1 is a top-down refreshed F3 image, that is, the F3 image of B1 overlaps the F2 image column by column from top to bottom. The image of B2 is an image that refreshes F3 from bottom to top, that is, the F3 image of B2 covers the F2 image column by column from bottom to top. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 9). At time T3, the F3 images of both B1 and B2 are refreshed (as shown in fig. 10). In the whole refreshing process of the F3 image, the F2 image is always displayed at the boundary of the B1 and the B2, so that the image can not be dislocated or torn. Therefore, the scanning mode of B1 from top to bottom and B2 from bottom to top solves the jelly effect of the display screens of B1 and B2. Similarly, taking the F3 image refresh process of the display screen of two columns B2 and B3 as an example: at the time T1, the images displayed by B1 and B2 are the same frame image, i.e., F2 image (shown in fig. 8). Then, the refresh of the F3 image is started, and the image of B2 is an image for refreshing F3 from bottom to top, that is, the F3 image of B2 is an image for covering F2 column by column from bottom to top. The image of B3 is a top-down refreshed F3 image, i.e., the F3 image of B3 overlays the F2 image column by column from top to bottom. At time T2, the F3 image and the F2 image are each displayed in half (as shown in fig. 9). At time T3, the F3 images of both B1 and B2 are refreshed (as shown in fig. 10). In the whole refreshing process of the F3 image, the F3 image is always displayed at the boundary of the B2 and the B3, so that the image is not misplaced or torn. Therefore, the scanning mode from bottom to top of B2 and from top to bottom of B3 also solves the jelly effect of the screen display of B2 and B3.
