Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to more clearly describe the split-screen display method provided in the embodiment of the present invention, an exemplary application scenario of the split-screen display method provided in the embodiment of the present invention is described below, and it should be understood that the split-screen display method provided in the embodiment of the present invention may also be applied to other application scenarios besides this example, which is not limited to this.
A plurality of LED screens can splice according to actual demand, form LED concatenation screen. Due to the fact that the number, the resolution ratio and the splicing mode of the LED screens are different, the resolution ratio of the spliced LED screens formed by splicing can be different, and therefore the resolution ratio of the spliced LED screens is various and is not always standard. For example, a plurality of LED screens may be spliced to form a 2560 × 1080-resolution LED spliced screen, and if the resolution of a source image transmitted by a source device requiring the spliced screen is standard resolution such as 1920 × 1080, the following two methods may be adopted in the related art:
the first method is as follows: as shown in fig. 1, a 1920 × 1080 source image is displayed on the left side of the LED tiled screen, and since the resolution of the new source image is not consistent with that of the LED tiled screen, a 640 × 1080 black edge exists on the right side of the LED tiled screen, as shown in the area filled with oblique lines in fig. 1, the black edge does not display any content, and thus, the display resources are wasted.
The second method comprises the following steps: the 1920 x 1080 source image is stretched to 2560 x 1080, and the stretched source image is displayed on the LED spliced screen, but the source image is distorted in the stretching process, so that the limited image quality on the LED spliced screen is poor, and the viewing experience is influenced.
Based on this, an embodiment of the present invention provides a split-screen display method, and referring to fig. 2, fig. 2 is a schematic flow diagram of the split-screen display method provided in the embodiment of the present invention, and the method may include:
s201, dividing a display screen into a plurality of areas.
The plurality of regions include a main picture region and at least one editable region, a difference value between an aspect ratio of resolution of the main picture region and an aspect ratio of resolution of the source image transmitted by the source device is smaller than a preset threshold, and the preset threshold can be set according to actual requirements. The aspect ratio may refer to a horizontal direction resolution to a vertical direction resolution, or may refer to a vertical direction resolution to a horizontal direction resolution. The preset threshold may be a preset value, such as 0.2 or 0.3, or may be determined according to a preset rule and an aspect ratio of the resolution of the main picture region or the source image, and for example, the preset threshold may be 0.1 (the aspect ratio of the source image), which is not limited in this embodiment.
For example, assuming that the resolution of the source image is 1920 × 1080, the aspect ratio of the resolution of the source image may be 1920:1080, i.e., 16:9, and if the preset threshold is 0.1 × (the aspect ratio of the source image), the aspect ratio of the resolution of the main picture region may be 14.4:9 to 17.6: 9, for example, the aspect ratio of the resolution of the main picture area may be 17:9, and the resolution may be 2040 × 1080 or 1020 × 540.
The aspect ratio of the resolution of the main picture region may also be completely consistent with that of the source image, that is, the aspect ratio of the resolution of the main picture region is 16:9, and the resolution may be 1920 × 1080 or 960 × 540. The position of the main screen area can be different according to different actual requirements, for example, in one possible embodiment, the main screen area can be located in the middle of the display screen, and in another possible embodiment, the main screen area can also be located at the top or bottom of the display screen. The number, size and position of the editable areas can be different according to different actual requirements, the different editable areas have no overlapped area, and any position in the display screen belongs to one of the areas.
Taking the resolution of the display screen as 2560 × 1080 and the resolution of the source image as 1920 × 1080 as an example, as shown in fig. 3a, the display screen may be divided into a main screen region and two editable regions, where the resolution of the main screen region may be 1920 × 1080 and the resolution of each editable region is 320 × 1080. In another possible embodiment, the two editable areas may have different resolutions, as shown in fig. 3b, the resolution of the editable area on the left part of the display screen is 480 × 1080, and the resolution of the editable area on the other part of the display screen is 160 × 1080.
Taking the resolution of the display screen as 1920 × 1720 and the resolution of the source image as 1920 × 1080 as an example, as shown in fig. 3c, the display screen may be divided into a main screen region and two editable regions, where the resolution of the main screen region is 1920 × 1080 and the resolution of each editable region is 1920 × 320. In another possible embodiment, as shown in fig. 3d, the display screen may be divided into a main screen region and an editable region, wherein the resolution of the main screen region is 1920 × 1080, and the resolution of the editable region is 1920 × 640.
S202, determining the content to be displayed corresponding to each editable area.
Each editable area corresponds to at least one content to be displayed, and the content to be displayed may be different according to different application scenes, for example, the content to be displayed may include preset text, a clock, weather information, an image, and the like. For example, the content to be displayed corresponding to one editable area may be an image, a clock, or both an image and a clock.
The content to be displayed corresponding to each editable area can be specified by the user by inputting an operation instruction. For example, a user may issue an editing instruction for any editable area by inputting an operation instruction at the client device, where the editing instruction includes one or more contents to be displayed, so as to designate the one or more contents to be displayed as the contents to be displayed corresponding to the editable area.
In a possible embodiment, the content to be displayed corresponding to each editable area may be read from a flash memory, where the content to be displayed issued by the client device for each editable area is stored in the flash memory in advance. Because the flash memory can not lose the stored information after power failure, the content to be displayed corresponding to each editable area is stored in the flash memory, and the content to be displayed corresponding to each editable area can be quickly determined after the breakpoint is restarted.
S203, controlling the display screen to display the source image in the main picture area, and displaying the content to be displayed corresponding to the editable area in each editable area.
The information source image and the content to be displayed corresponding to each editable area can be spliced according to the arrangement mode of the plurality of areas to obtain a spliced image. And controlling a display screen to display the spliced image. For example, assuming that the plurality of regions are arranged as shown in fig. 1, the content to be displayed corresponding to one editable region may be spliced to the left side of the source image, and the content to be displayed corresponding to another editable region may be spliced to the right side of the source image, so as to obtain a spliced image. The stitched image obtained by stitching may be as shown in fig. 4.
Because the difference value of the aspect ratio of the resolution of the source image and the resolution of the main picture area is smaller than the preset threshold value, the source image is displayed in the main picture area, and even if the resolution of the source image is inconsistent with the resolution of the main picture area, the source image is hardly distorted in the process of stretching the source image because the change of the aspect ratio of the resolution is small, so the influence of stretching on the image quality of the source image is small. When the aspect ratio of the resolution of the main picture area is consistent with that of the source image, the source image is not distorted even by stretching, and meanwhile, the editable area also displays corresponding content, so that the waste of display resources is reduced. Therefore, the embodiment can reduce the image quality reduction caused by stretching the source image on the premise of reducing the waste of display resources.
For convenience of description, the description will be given by taking an example that the resolution of the display screen is 2560 × 1080 and the resolution of the source image is 1920 × 1080 as an example, and the principle is the same for other application scenarios, and reference may be made to fig. 5a, where fig. 5a shows an initial interface of a configuration interface of split-screen display provided in an embodiment of the present invention.
The interface comprises two rectangular frames, wherein the larger rectangular frame represents the display screen, the smaller rectangular frame (the rectangular frame marked by thick black sides) represents the main picture area, and the ratio of the sizes of the two rectangular frames is the same as the ratio of the resolution of the display screen to the resolution of the main picture area. The user can drag the rectangular frame representing the main screen area according to actual needs, so that the rectangular frame representing the main screen area moves within the rectangular frame representing the display screen. The user can also zoom the rectangular box representing the main picture area to change the resolution of the main picture area (in other possible application scenarios, the resolution of the main picture area can also be changed in other ways)
The rectangular frame representing the main picture area divides the rectangular frame representing the display screen into three areas, wherein one area is the area where the rectangular frame representing the main picture area is located, and the other two areas respectively represent an editable area. The user can edit the contents to be displayed corresponding to the two areas. Illustratively, the user may right click on the right area through a mouse, pop up an edit menu as shown in fig. 5b, and left click on any instruction of addition, deletion, and modification in the menu.
If the adding instruction is selected, the corresponding content to be displayed can be added to the area, for example, a clock can be added to the area as the content to be displayed corresponding to the area. If the deletion instruction is selected, any content to be displayed corresponding to the area can be deleted. If the editing instruction is selected, any content to be displayed corresponding to the region may be edited, for example, the content to be displayed corresponding to the region includes the clock of the style a, the clock of the style a may be modified to the clock of the style B through the editing instruction, or the position of the clock of the style a in the region may be modified. The configuration interface after the configuration is finished may be as shown in fig. 5c, that is, the content to be displayed corresponding to the left editable area includes a picture 1, a clock and a preset text "hang welcome you", and the content to be displayed corresponding to the right editable area includes a picture 2, information on duty and a preset text "XXXXXX", so that a picture displayed on the display screen during split-screen display may be as shown in fig. 5 d.
