and step S3, displaying an identification icon related to the target picture in the pre-monitoring picture operation area according to the position of the target picture relative to the pre-monitoring picture operation area.
Referring to fig. 6, the pre-monitor screen operation area 210 (also referred to as PVW window) belongs to a part of the multi-source pre-monitor screen 200, the pre-monitor screen operation area 210 includes a canvas 211 and a plurality of screens (such as screen 213 and screen 214 shown in the figure), the multi-source pre-monitor screen 200 further includes a plurality of video source display areas 230, the video source display areas 230 are used for displaying video source screens, wherein the screens are selected from the video source screens, and the multi-source pre-monitor screen 200 further includes a presentation screen display area 220 (also referred to as PGM window).
As mentioned above, determining the position of the target screen relative to the pre-monitoring screen operating area 210 includes determining that the target screen is located within the pre-monitoring screen operating area 210, which may be in response to a user selecting at least one screen within the pre-monitoring screen operating area 210 as the target screen, where the at least one screen is a screen located within the pre-monitoring screen operating area 210; it is also possible that in response to the user selecting at least one video source picture in the plurality of video source display areas 230 and adding it to the pre-monitored picture operating area 210, a picture associated with the video source picture is generated within the pre-monitored picture operating area 210 and is taken as a target picture.
As mentioned above, referring to fig. 7, the identification icon is an identification icon associated with the target picture generated on the multi-source pre-monitoring picture 200 according to the position information of the target picture (e.g. picture 213) on the pre-monitoring picture operation area 210, and the identification icon may be a color identification, for example, a default color is displayed on the outline of the target picture to distinctively display the target picture so that the user can intuitively determine the target picture from the pre-monitoring picture operation area 210; the identification icon may also be an image identification, which is not limited herein.
Referring to fig. 2, in one embodiment, the step S3 includes, for example:
step S31, obtaining an identification icon used for representing the target picture according to the position of the target picture relative to the operation area of the pre-monitoring picture;
step S33, displaying the identification icon in the pre-monitoring screen operation area.
In the above, the identification icon is displayed in the pre-monitoring screen operation area, so as to identify the target screen, so that the user can intuitively determine the target screen from the multi-source pre-monitoring screen 200, that is, the position of the target screen in the pre-monitoring screen operation area 210 and the screen content thereof are determined, so that when the user responds to operations such as selection and adjustment of the target screen, the target screen can be intuitively determined through the identification icon, and the change of the target screen can be seen.
Referring to fig. 3, in an embodiment, when the target screen is located in the pre-monitoring screen operation area, the step S31 includes:
step S311, acquiring the picture position information of the target picture in the pre-monitoring picture operation area and the picture size of the target picture;

Referring to fig. 5, the screen identification method further includes, for example:
step S5, performing the same scaling process on the identification icon according to the scaling factor while performing the scaling process on the target screen according to the scaling factor.
The scaling process for the target picture may be a scaling process for the target picture in response to a user operation, so that the identification position information and the identification size of the identification icon are also changed correspondingly, that is, the target picture and the identification picture are scaled according to the same scaling factor, that is, the identification icon is scaled (or scaled) as the target picture is scaled (or scaled).
In one embodiment, when the target screen is located outside the pre-monitoring screen operation area, the step S3 further includes: and obtaining the identification icon at the boundary of the relative directions of the pre-monitoring picture operation area and the target picture.
In view of the above, when the offset of the initial position (0,0) of the target screen relative to the initial position (0,0) of the pre-monitor screen operation area is negative or larger than the size of the pre-monitor screen operation area, that is, the target screen cannot be displayed in the pre-monitor screen operation area, it is determined that the target screen is located outside the pre-monitor screen operation area.
For example, the target screen may be moved in response to a user operation, the target screen moves in the pre-monitoring screen operation area 210, and when the target screen exceeds the pre-monitoring screen operation area 210, an identification icon corresponding to the target screen is displayed at a boundary of the target screen and the pre-monitoring screen operation area 210 in the opposite direction; that is, when the position information of the target screen exceeds the pre-monitored screen operation area 210, the boundary of the pre-monitored screen operation area 210 closest to the position information of the target screen is set as the identification position information, and finally the identification icon corresponding to the target screen is obtained, for example, a red cross-shaped icon is displayed at the boundary of the pre-monitored screen operation area 210.
For clear understanding of the picture identification method provided by the embodiment of the present invention, the picture identification method will now be described in detail with reference to the implementation processes provided in fig. 6 to 7:
referring to fig. 6, it is a schematic diagram of an architecture of a multi-source pre-monitoring screen 200, where the multi-source pre-monitoring screen 200 includes a pre-monitoring screen operating region 210, and a size of the pre-monitoring screen operating region 210 may be obtained by scaling down according to a size of an LED display large screen; the multi-source pre-monitor screen 200 further includes a plurality of video source display areas 230, the video source display areas 230 being for displaying video source screens, and the screens (e.g., screen 213 and screen 214) in the pre-monitor screen operating area 210 being from the video source screens.
According to the method, a user can set a window which is positioned in a display range of an LED display large screen and is used for displaying a video source picture, and correspondingly, a pre-monitoring picture corresponding to the video source picture is displayed in a pre-monitoring picture operation area; for another example, if the window opened by the user is located outside the display range of the LED display large screen, the pre-monitoring picture corresponding to the video source picture displayed in the window is located outside the pre-monitoring picture operation area.
Responding to the user operation to obtain a window (including a window positioned outside the LED display large screen) arranged on the LED display large screen, and correspondingly obtaining a target picture in (or outside) the operation area of the pre-monitoring picture, namely, taking a picture to be edited by the user currently as the target picture; after the target picture is determined, the offset of the starting point of the target picture relative to the starting point of the pre-monitoring picture operation area 210 is determined to obtain the position information of the target picture, and the width and the height of the target picture on the pre-monitoring picture operation area 210 are determined to obtain the picture size of the target picture.
Further, the four vertex positions of the target picture are obtained as identification position information according to the position information of the target picture, and the identification size is obtained according to the width and the height of the target picture, for example, the identification size (i.e., the width and the height) is determined in the horizontal direction and/or the identification size (i.e., the width and the height) is determined in the vertical direction along the contour of the target picture according to the vertex of the target picture.
In light of the above, the pre-monitoring screen operation area 210 includes the screen 213 and the screen 214, where the screen 214 and the screen 213 are completely located in the pre-monitoring screen operation area 210, and when the screen 213 is used as a target screen, the mark icon is obtained according to the position information and the screen size of the screen 213 (see the schematic configuration diagram shown in fig. 7). Specifically, the identification position information and the identification size of the identification icon associated with the picture 213 are obtained according to the position information and the size of the picture 213, and an identification icon region is further obtained, wherein the identification icon region may be a continuous complete region or a combination of a plurality of discontinuous regions, and then the color data of the pixel points in the identification icon region is replaced by the target color data corresponding to the identification color information according to the identification color information; for example, the identification color information corresponds to red.
In an embodiment, color data of pixel points in the identification icon region may be periodically replaced with target color data corresponding to the identification color to obtain a dynamically flashing identification icon.
In summary, the embodiments of the present invention can solve the following problems: i) in the pre-monitoring picture operation area, when a target picture to be edited by a user is shielded by a picture with higher priority, the target picture to be edited by the user is positioned at other positions of the pre-monitoring picture operation area outside a canvas, and the change of the target picture currently edited by the user is small and cannot intuitively guide the user to focus, the user cannot intuitively find and determine the target picture currently edited from the pre-monitoring picture operation area; ii) obtaining the identification position information and the identification size of the identification icon according to the position information and the picture size of the target picture on the pre-monitoring picture operation area, further obtaining the identification icon area, and replacing the pixel data of the pixel points in the identification icon area corresponding to the pre-monitoring picture operation area with the pixel data corresponding to the identification color information.
