Example Embodiment

[0073] Example one:

[0074] Such as figure 2 Shown here is a flow chart of the steps of an image display method provided in Embodiment 1 of the present invention. The method is mainly applied to the process of displaying images on a mosaic display device, which generally includes a plurality of display units, Moreover, there are splicing seams between adjacent display units due to the borders of the display units.

[0075] The image display method includes:

[0076] Receive the image to be displayed;

[0077] When it is determined that a character is contained in the preset divided area, the position of the character is moved so that the character is not contained in the preset divided area.

[0078] When the preset division area in the spliced ​​display device is the splicing seam of the spliced ​​display device, the above method specifically includes the following steps:

[0079] Step 101: Receive an image to be displayed, where the image to be displayed includes a character window....

Example Embodiment

[0095] Embodiment two:

[0096] Take as image 3 As an example, the spliced ​​display device composed of 2×2 display units is shown, where the display unit in the upper left corner is the first display unit, the display unit in the upper right corner is the second display unit, and the display unit in the lower left corner is the third display Unit, the display unit in the lower right corner is the fourth display unit. The resolution of each display unit is M×N, the horizontal resolution corresponding to the vertical stitching is 2a, the vertical resolution is 2N+2b, and the horizontal resolution corresponding to the horizontal stitching is 2M+2a and the vertical resolution is 2b; According to the distribution position and combination of the 4 display units, the resolution of the mosaic display device composed of the 2×2 display units can be obtained as (2M+2a)×(2N+2b), and the resolution of the mosaic display device includes Display the resolution of the unit and stitching.

Example Embodiment

[0102] Example 1:

[0103] If it is detected that there is a character in the vertical splicing seam of the i-th character line, part or all of the character and the vertical splicing seam (coordinates are (M, 0), (M+2a, 0) , (M, 2N+2b) and (M+2a, 2N+2b)) overlap, and the characters overlap with the projection of the central axis of the splicing seam. The line of the character spans the first display unit and the second display unit.

[0104] Get the left boundary coordinate Xi of the character in the horizontal direction left And the right boundary coordinate Xi right ; In particular, when the central axis of the splicing seam overlapping with the character is at the same distance from the left and right borders of the character, the extension line of any of the two borders is determined as the segmentation line.

[0105] (1) As shown in Figure 5(a), when |Xi left -(M+a)| rightt -(M+a)|When the left boundary coordinate Xi of the character "please" left The extension line where...

Abstract

The invention discloses an image processing method and device applied to tiled display equipment. Specifically, the image processing method mainly comprises the step that when it is confirmed that a preset division region contains a character, the character is moved to enable the preset division region not to contain the character. Thus, it is guaranteed that the character can be completely displayed in one display unit, the problems that in the prior art, characters located at seam positions are locally or completely lost and a single character at one seam position is displayed in two display units in a crossing mode are avoided, and a better character display effect is guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an image processing method and device applied to a spliced ​​display device. Background technique [0002] At present, when displaying a large-sized image, a splicing display device formed by splicing a plurality of display units can be used for display. When displaying an image, it is necessary to determine the preset segmentation area according to the number and position of the display units in the splicing display device, and segment the image to be displayed, and transmit the segmented sub-images to each display unit for further processing. show. [0003] In the prior art, since each display unit has a frame structure that cannot display images, when multiple display units are spliced ​​together, seams will inevitably be generated, and images cannot be displayed in the area of ​​the seams , therefore, when the image is segmented, the area where the seam is located ...
