Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In consideration of the fact that in the prior art, the window of the player is enlarged, reduced or dragged through a mouse, the precision of the mouse for changing the window is difficult to achieve the pixel level, the changed window can cover a plurality of screens, each screen only covers one part, so that the area covered by the window in the same screen displays a 3D (three-dimensional) picture, the uncovered part displays a 2D (two-dimensional) picture, and the display effect of the spliced screen is greatly reduced. Based on this, embodiments of the present invention provide an adaptive method and apparatus for a player, which are described below by way of embodiments.
Example 1
The embodiment of the invention provides a window self-adaption method of a player. When 3D display is carried out through the spliced screen, if a user enlarges or reduces the window of the player or drags the window when the window area of the window is kept unchanged, the method provided by the embodiment of the invention can ensure that the window is adaptively adjusted to be covered by the whole screen after being enlarged, reduced or dragged, namely, one or more sub-screens in the spliced screen are adaptively covered. Thus, 3D pictures are displayed in one or more sub-screens adaptively covered by the window, and 2D pictures or other 3D pictures are displayed in other sub-screens not covered by the window.
Before the window self-adaptation is performed by the method provided by the embodiment of the present invention, the whole screen information corresponding to different sub-screen combination modes needs to be stored in the host for controlling the spliced screen in the following manner, which specifically includes:
determining a plurality of whole screen groups according to the number of sub-screens included in the spliced screen; acquiring coordinate information, window area, optical parameters and resolution of a window corresponding to each whole screen group; and respectively storing the coordinate information, the window area, the optical parameter and the resolution ratio corresponding to each whole-screen group as the whole-screen information corresponding to each whole-screen group.
The whole screen group includes one sub-screen or includes a plurality of adjacent sub-screens. The tiled screen shown in fig. 1 is a 2 x2 sub-screen array consisting of 1011, 1012, 1021, 1022 four sub-screens. Then, according to the 4 sub-screens included in the mosaic screen, the determined whole screen grouping may be [1011, 1012, 1021, 1022] including the 4 sub-screens, [1011, 1012], [1011, 1021], [1021, 1022] and [1012, 1022] including two sub-screens, and [1011], [1012], [1021] and [1022] including only one sub-screen.
Because [1011, 1012], [1011, 1021], [1021, 1022] and [1012, 1022] comprising the two sub-screens are all rectangles, if a window of the player covers [1011, 1012], [1011, 1021], [1021, 1022] or [1012, 1022] comprising the two sub-screens, when the film source file is played through the window, the 3D picture is widened, and the 3D display effect is affected. Therefore, when the spliced screen is grouped in a whole screen mode, the screen areas corresponding to the whole screen grouping are preferably grouped in a square mode. However, it should be noted that, for the screen grouping mode in which the corresponding screen area is rectangular, the window adaptation can also be performed according to the method provided by the embodiment of the present invention, and the method is within the scope of the present invention.
The embodiment of the invention does not particularly limit the division mode of the whole screen grouping, and a new grouping mode can be set or selected according to the size of the actual screen, the placement position of the spliced screen, the viewing distance of a user and other specific environmental conditions in practical application. When the screen grouping is carried out, the number of the sub-screens included in the screen grouping is not fixed, in practical application, the adjacent sub-screens can be selected as the screen grouping according to actual requirements and resources in the aspect of existing film source files, and optical parameters matched with the screen grouping are designed or calculated, so that the optimal naked-eye 3D display effect is achieved.
After a plurality of whole-screen groups are obtained according to the spliced screen in the mode, for each whole-screen group, the coordinate information, the window area, the optical parameters and the resolution of the window corresponding to the whole-screen group are obtained. In the embodiment of the invention, a coordinate detection module is configured in the player, and a coordinate system establishing unit included in the coordinate detection module establishes a coordinate system based on the horizontal and vertical resolutions of the spliced screen, that is, the upper left corner of the spliced screen is taken as a starting point, the first pixel coordinate of the upper left corner is (1,1), and the maximum values of the X axis and the Y axis are the horizontal physical pixel number and the vertical physical pixel number of the spliced screen respectively. And the coordinate detection module acquires the coordinate information of the window corresponding to the whole screen group by referring to the established coordinate system.
The coordinate information comprises four vertex coordinates and center coordinates of a screen area corresponding to the whole screen grouping. The optical parameters are related information required when the film source is processed, such as the pixel number of a screen area corresponding to the whole screen group, the parameters of the 3D optical film and the like. The resolution is the number of horizontal pixels and the number of vertical pixels of the screen area corresponding to the whole screen grouping.
And after obtaining the coordinate information, the window area, the optical parameters and the resolution ratio corresponding to the whole-screen group, forming the obtained information into whole-screen information corresponding to the whole-screen group, and storing the whole-screen information corresponding to the whole-screen group. And for each other whole-screen group, respectively acquiring the coordinate information, the window area, the optical parameter and the resolution corresponding to each other whole-screen group in the same manner, and respectively storing the coordinate information, the window area, the optical parameter and the resolution as the whole-screen information corresponding to each other whole-screen group.
In order to ensure the point-to-point display of the picture in the window of the player, the film source file needs to be adapted to the resolution of the window. Therefore, after the whole screen information corresponding to each screen group is stored in the host controlling the spliced screen, the film source file corresponding to the resolution of each whole screen group is also obtained, and the corresponding relation between the resolution and the film source file is stored in the host controlling the spliced screen.
When storing the film source files corresponding to different resolutions, a folder can be created for each resolution, and only the film source file corresponding to the resolution is stored in the folder corresponding to the resolution, so that when playing the film source files, the corresponding folder can be quickly indexed according to the resolution of the window, and the film source file corresponding to the resolution can be obtained from the folder.
In the embodiment of the invention, because the plurality of whole-screen groups are divided according to the spliced screen, when the film source file is stored, only the film source file corresponding to the resolution of the divided whole-screen groups is stored, the mutual correspondence between the film source file and the resolution can be realized, and the number of the whole-screen groups is limited, so that the stored film source file corresponding to the resolution is not too much, and the storage space is not occupied too much.
Referring to fig. 2, the method specifically includes the following steps:
step 101: when a change event for changing the size and/or position of the window of the player is monitored, coordinate information of the changed window and change trend information of the window are obtained.
In the embodiment of the present invention, as shown in fig. 3, a coordinate detection module, a window position control module and a window display control module are configured in the player. The coordinate detection module comprises a coordinate system establishing unit, a current coordinate recording unit, a new coordinate recording unit and a change trend recording unit. The window position control module comprises a determination signal receiving module and a window coordinate determination unit. The window display control module comprises a window position updating unit, an optical parameter and resolution ratio extracting unit and a film source extracting and playing unit.
The coordinate detection module comprises a current coordinate recording unit for automatically detecting the current coordinate information of a window of the player, wherein the current coordinate information comprises four vertex coordinates and a center coordinate of the window when the player is started. The current coordinate information may be the coordinate information of a default window when the player is opened, such as the coordinate information of a default full-screen window. Alternatively, the current coordinate information may be the coordinate information of the last time the front window of the player was closed.
And the window control module monitors the window of the player in real time. When a user operates a window of the player through a mouse, a keyboard shortcut key or a wireless remote control mode, and the like, changes the size of the window of the player, or drags the position of the window on the premise of keeping the size of the window unchanged, the window playing control module can monitor a change event of operating the window, and at the moment, the window control module can acquire coordinate information and change trend information of the changed window through the window coordinate determination unit. Or after the change event is monitored, the user submits a window position determination signal through equipment such as a mouse, a keyboard shortcut key or a wireless remote control. The window control module comprises a determining signal receiving module which obtains the coordinate information and the change trend information of the changed window through a window coordinate determining unit after receiving a window determining signal submitted by a user.
The change trend information packet is a window area change trend of the window. And after the window coordinate determination unit acquires the coordinate information of the changed window, the window area of the window before being changed is calculated according to the current coordinate information of the window before being changed. And calculating the window area of the changed window according to the changed coordinate information. Comparing the window areas of the windows before and after changing, and determining whether the window area of the window after changing is smaller, larger or unchanged, thereby obtaining the window area change trend of the window.
And after the window coordinate determining unit obtains the coordinate information and the change trend information of the changed window, the coordinate information is transmitted to a new coordinate recording unit of the coordinate detection module, and the new coordinate recording unit stores the changed coordinate information. And the window coordinate determination unit transmits the change trend information to the change trend recording unit, and the change trend recording unit stores the change trend information.
In the embodiment of the invention, the new coordinate recording unit can store the changed coordinate information and the window area of the changed window at the same time, so that the window area can be directly used in the subsequent processing process, and the processing time is saved.
Step 102: and determining the self-adaptive whole-screen coordinate information of the window according to the changed coordinate information, the changed trend information and the pre-stored whole-screen information.
According to the change trend information, selecting whole screen information meeting preset change conditions from the pre-stored whole screen information; determining the whole screen information closest to the window after the distance is changed according to the coordinate information and the selected whole screen information; and determining the whole screen information as the whole screen coordinate information adaptive to the window.
The preset change condition is that if the area change trend information included in the change trend information shows that the window area of the changed window is increased, the whole screen information with the window area larger than that of the window before being changed is selected from the pre-stored whole screen information, the difference value between the window area included in each piece of selected whole screen information and the window area of the changed window is respectively calculated, and the whole screen information with the minimum difference value is selected from the selected whole screen information; if the area change trend information shows that the changed window area is smaller, selecting whole-screen information with the window area smaller than that of the window before changing from the pre-stored whole-screen information, respectively calculating the difference value between the window area of the window after changing and the window area included in each selected whole-screen information, and selecting the whole-screen information with the minimum difference value from the selected whole-screen information; and if the area change trend information shows that the changed window area is not changed, selecting the whole screen information of which the window area is equal to the changed window area from the pre-stored whole screen information.
And after the whole screen information is selected according to the change trend information, acquiring any one coordinate of the four vertex coordinates and the center coordinate from the changed coordinate information, and acquiring the coordinate of the same direction from the coordinate information included in the selected whole screen information. That is, if the center coordinate is selected from the changed coordinate information, the center coordinate is also acquired from the entire screen information, and if the vertex coordinate of the upper left corner is selected from the changed coordinate information, the vertex coordinate of the upper left corner must be acquired from the entire screen information. After the coordinates are selected, the distance between the coordinates selected from the changed coordinate information and the coordinates obtained from each whole screen information is respectively calculated, and the whole screen information with the minimum distance is determined as the whole screen coordinate information adaptive to the window.
In the embodiment of the invention, if only one whole screen information is selected according to the change trend information, the selected whole screen information is directly determined as the window self-adaptive whole screen coordinate information.
In order to facilitate understanding of the selection process of the whole screen information, the following description is made with reference to fig. 1. As shown in FIG. 1, Windows W1100 of the current player covers all the sub-screens of the mosaic. When the user zooms out the window W1100 to the window W1200 shown in fig. 1, the determined change trend information is that the area is reduced. Firstly, the whole screen groups [1011], [1012], [1021], [1022] with window areas smaller than the window area of the front window W1100 are selected from the pre-stored whole screen information according to the area change trend, then the window areas of the whole screen groups are obtained from the whole screen information corresponding to the whole screen groups [1011], [1012], [1021], [1022] respectively, the difference between the window areas corresponding to the whole screen groups [1011], [1012], [1021], [1022] respectively and the window area of the window W1200 is calculated respectively, and the whole screen group with the minimum difference is selected, wherein the whole screen group with the minimum difference is [1011], [1012], [1021], and [1022] selected in the example. Distances are respectively calculated between the center coordinate of the window W1200 and the center coordinates of [1011], [1012], [1021] and [1022], and the whole screen grouping with the minimum distance is selected. The whole screen with the minimum distance in the example is grouped as [1021], and the whole screen information corresponding to [1021] is determined as the whole screen coordinate information adaptive to the window. And then the window of the player is adaptively adjusted to [1021], namely the window W1300 of the player after adaptive processing covers the whole area of the sub-screen 1021.
Step 103: and carrying out self-adaptive adjustment on the window according to the coordinate information of the adjustment screen.
Determining whether the window area of the changed window is changed or not according to the change trend information by a window position updating unit included in the window display control module; if so, calculating the area of the whole screen window according to the whole screen coordinate information, and adjusting the window area of the window into the area of the whole screen window; and moving the window with the adjusted area to a position corresponding to the coordinate information of the whole screen. If not, the window is directly moved to the position corresponding to the coordinate information of the whole screen.
Since the screen area covered by the adaptive rear window is different from the screen area covered by the adaptive rear window, the optical parameters corresponding to the changed rear window are changed, and if the window area of the window is changed, the resolution of the window is changed accordingly. In order to ensure that point-to-point 3D picture display is realized through the self-adaptive window, after the self-adaptive adjustment is carried out on the window, optical parameters and resolution corresponding to the coordinate information of the whole screen are obtained through an optical parameter and resolution extracting unit included by a window display control module; the configuration file in the player is updated according to the optical parameters and the resolution. Namely, the optical parameters and the resolution in the configuration file of the player are respectively replaced by the optical parameters and the resolution corresponding to the whole-screen coordinate information.
After the configuration file of the player is updated, whether the resolution corresponding to the coordinate information of the whole screen is the same as the resolution of the changed window or not is judged through the film source extracting and playing unit; if not, acquiring a corresponding film source file according to the resolution; and calling the player to process and play the film source file in the window after the adjustment operation. And if the resolution ratio of the front window and the rear window is not changed in the self-adaption mode, the film source file is not acquired again, and the original film source file is processed and played through the new window. In the whole spliced screen, the film source file is played in the self-adaptive window, and a 3D picture is displayed. In other sub-screens besides the sub-screen covered by the window, 2D pictures, such as other promotional information like 2D text, pictures or videos, or brief description information related to the film source file being played by the window, etc. may be displayed. In addition, other 3D pictures can be displayed in other sub-screens except the sub-screen covered by the window, corresponding film source files are acquired according to the resolutions of the other sub-screens, and the acquired film source files are processed and played in the other sub-screens.
In the embodiment of the invention, after the self-adaptive operation is carried out on the window, the current coordinate information stored in the current coordinate recording unit included by the coordinate detection module is deleted, and the whole-screen coordinate information of the self-adaptive window is stored in the current coordinate recording unit. If the size or position of the window is changed again by the subsequent user, the self-adaptive processing of the window is carried out on the basis of the whole screen coordinate information.
For further understanding of the window adaptive method provided by the embodiment of the present invention, the following description is made with reference to the accompanying drawings. For example, the tiled screen shown in fig. 1 is a 2 × 2 naked-eye 3D tiled screen, the resolution of each sub-screen is 1920 × 1080, and the resolution of the tiled screen is 3840 × 2160. The screen groups divided for the spliced screen comprise [1011, 1012, 1021, 1022], [1011], [1012], [1021] and [1022], namely 1011, 1012, 1021 and 1022 are full screen display 3D pictures; or 1011 full screen displays 3D pictures, 1012, 1021, and 1022 display 2D pictures; or 1012 full screen display of 3D picture, 1011, 1021, and 1022 display of 2D picture; or 1021 full screen display 3D picture, 1011, 1012 and 1022 display 2D picture; or 1022 full screen display 3D picture, 1011, 1012 and 1021 display 2D picture. After the screen grouping is determined, 1 pixel is taken as 1 unit, and the coordinate information corresponding to the window can be obtained from the position and the number of the sub-screens. The resolution of the 1 st packet was 3840 × 2160, the resolution of the last 4 packets was 1920 × 1080, and the optical parameters of the 5 packets were different.
