It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a method for 3D video display according to an embodiment of the present invention, where the method is applicable to a case of 3D video display, and the method may be executed by a device for 3D video display, where the display device may be disposed in an operating system layer, implemented in a form of software and/or hardware, and may be configured in an electronic device, where the electronic device is typically a terminal device, and optionally, a mobile phone, a tablet, or a PC terminal.
As shown in fig. 1, the method of this embodiment includes:
s110, when application program window information corresponding to the video to be played is received, the application program window information is sent to the three-dimensional video service assembly, so that the three-dimensional video service assembly can determine whether the application software corresponding to the application program window information supports 3D display or not according to the application program window information.
It should be noted that the method may be applied to a mobile terminal, may also be applied to a PC terminal, and of course, may also be applied to other devices or terminals, and the scheme of the embodiment of the present invention may be applied only if the terminal or the device is capable of implementing 3D display, and the specific application scenario is not limited herein.
Wherein, the window can understand each window displayed by the current display interface. For example, the window may be a window in which a video or an image is to be played on the current display interface, and optionally, if the user triggers an icon of the cool video, a display interface corresponding to the triggering instruction may be displayed on the display interface. If the user triggers an instruction to open a certain movie again, the window is the interface for playing the movie at present. The application window information may be understood as: the window information corresponds to the current window and comprises window numbers, marks corresponding to the playing software and other information.
In different operating systems, the window composition manager may have different names, and of course, the main role is to display the content to be played back on the screen with the application software, i.e., the playback software. In the three-dimensional video service component, a software name supporting the rearrangement can be preset, that is, a software list supporting the rearrangement is stored in advance. It can be understood that in the three-dimensional video service component, a list of software supporting three-dimensional display of video, called a white list, is stored in advance, software in the white list supports 3D display, and software outside the white list does not support 3D display. The method has the advantages that when the window information of the application program is sent to the three-dimensional video service assembly, whether the playing software can be played in a unit can be judged, and then a user can be reminded in advance whether the display mode of the display interface needs to be switched. It should be noted that the display device may be a three-dimensional display or a two-dimensional television, and when two-dimensional display is required, the switch button corresponding to the display screen may be adjusted to two-dimensional display.
When the window composition manager receives the application window information, in order to determine whether the video to be played can be three-dimensionally displayed, the application window information may be sent to the three-dimensional video service component for determination.
Specifically, the application window information corresponding to the video to be played is sent to the window composition manager. The application program window information comprises a window number and a playing software identifier. The window synthesis manager sends the application program window information to the three-dimensional video service assembly, and the three-dimensional video service assembly can determine whether the playing software is on a stored white list according to the playing software identification, and further determine whether the application software corresponding to the application program window information supports 3D display.
In this embodiment, at least three embodiments may exist for receiving an application window corresponding to a video to be played. The first embodiment may be that, when it is detected that at least one window is to be subjected to video playing, application window information corresponding to at least one window is acquired, and the application window information is sent to the window composition manager.
Such an embodiment may be understood as: more than one window can be displayed on the terminal or the device, and optionally, if at least two windows are to play videos, the application program window information corresponding to each window is acquired respectively. The application window information may include a window number or a window ID corresponding to each window, and playback software corresponding to each window, that is, software through which the window is played. And respectively sending the detected application program window information to the window synthesis manager. And sending the application program window information to the three-dimensional video component by the window synthesis manager, and further determining whether the application software corresponding to the application program window information supports 3D display. The advantage of this arrangement is that once it is detected that there is a video to be played, the corresponding application window information can be obtained, the 3D display button corresponding to each window does not need to be triggered, and the operation is simple.
In a second embodiment, when receiving an instruction to display a video to be played in 3D, application window information corresponding to the play instruction may be acquired.
Specifically, it may be understood that, when a user triggers a certain piece of playing software to play a video, a dialog box indicating whether to perform 3D display, that is, a switching button for 3D display, may be popped up before playing the video, and if the user triggers a button for 3D display, the application window information corresponding to the window may be sent to the window composition manager, so that the window composition manager determines whether the playing software supports 3D display.
When an instruction for performing 3D display on a video to be played is received, acquiring application program window information corresponding to the playing instruction, and the method has the advantages that when at least two windows are to be played on a display interface, the application program window information corresponding to all the windows does not need to be acquired respectively, and only the application program window information corresponding to the triggering 3D display instruction needs to be acquired according to which window the user triggers the 3D display instruction. A third embodiment may be that when it is detected that at least two windows are to be played, application window information corresponding to the windows is respectively obtained, if it is determined that at least two applications are both capable of 3D display, a switch button for determining whether to 3D display is popped up on the window, and at the same time, the window composition manager may obtain an image corresponding to the video to be played, and receive the interleaving parameter information.
In the above three embodiments, the user may set one or more of them according to actual requirements, and which embodiment is specifically adopted by the user is not limited herein.
And S120, if the application software supports 3D display, the window synthesis manager determines a preprocessed image corresponding to each frame of image in the video to be played, and combines the preprocessed image with the received interleaving parameter information to perform image arrangement processing to obtain the image to be interleaved corresponding to the preprocessed image.
The three-dimensional video service component may determine whether software corresponding to the application window information supports 3D display, that is, whether the application software is in a white list, according to the received application window information. If the application software is in the white list, it may be determined that the application software supports 3D display, and if the application software is not in the white list, it is determined that the application software does not support 3D display.
If the software corresponding to the application window information supports 3D display, the window composition manager may obtain a preprocessed image corresponding to each frame of video in the video to be played. Meanwhile, the window composition management may also receive hardware parameter information of the display device, that is, interleaving parameter information, optionally, the width of the prisms, the distance between the prisms, and the eye tracking module detects the eye position information, and the above parameters may all be referred to as interleaving parameter information. And the window synthesis manager arranges the images to be processed according to the received interweaving parameter information to obtain the images to be interwoven. The layout can be understood as that the window composition manager rearranges each pixel point of the preprocessed image, and the basis of the rearrangement is the interleaving parameter information received by the window composition manager.
It should be noted that the interleaving parameter information may be sent by an interleaving parameter generation module in the three-dimensional video service component; or may be sent by a separate interleaving parameter module. That is, the interleaving parameter generation module can be provided in the operating system as a separate module, and can also be integrated in the three-dimensional video service component.
In this embodiment, the window composition manager further includes a re-mapping module, where the re-mapping module may determine, according to the pre-processed image and the interleaving parameter information, a position of each pixel point of the pre-processed image on the display screen, that is, perform pixel point rearrangement on an image corresponding to each frame of video in the video to be played.
The rearrangement module is named only by its function, and is not limited to be only a rearrangement module, and may be other names as long as the function of the rearrangement can be realized.
On the basis of the technical scheme, when the pre-processed image is subjected to layout according to the interweaving parameter information, the human eye position of the user needs to be determined, so that a human eye tracking module can be arranged for acquiring the human eye position of the user. The eye tracking module can be arranged in the three-dimensional video service assembly, can also be arranged in window synthesis management and the like, and can be arranged by a user according to actual requirements. The eye position information may also be referred to as interleaving parameter information.
Specifically, the rearrangement module in the window composition manager may rearrange each pixel point of the preprocessed image according to the received interleaving parameter information, so as to obtain the image to be interleaved.
S130, when the image to be interleaved is displayed by the 3D display device, the interleaved image corresponding to each frame of image is obtained, and all the interleaved images are played in sequence so as to enable the video to be played to be displayed in a 3D mode.
When the image to be interlaced is displayed by the 3D display device, pixels in odd columns or pixels in even columns may enter the left eye or the right eye of the user, respectively, by refraction of a prism or other components, or the like. It should be noted that the image displayed by the display device may be referred to as an interlaced image, and the window composition manager may sequentially display the images to be interlaced on the corresponding windows, so that the video to be played achieves the effect of 3D display.
On the basis of the above technical solution, it should be noted that, when 3D display is performed on a video, the operation mode of the display screen needs to be adjusted to the 3D display mode.
On the basis of the above technical solution, it should be noted that a video is composed of one frame of image, and therefore, when the video includes only one frame of image, the video can be understood as an image, that is, the image is displayed three-dimensionally. Therefore, the technical solution of the embodiment of the present invention can be applied to a range including video and images, both of which support the display in a 3D manner, and can also include, that is, can also be applied to other contents that need to be displayed in a 3D manner. When displaying an image, the display mode is the same as the processing mode described in the embodiment of the present invention, and reference may be made to the technical solution of the embodiment of the present invention, which is not described herein.
According to the technical scheme of the embodiment of the invention, when application program window information corresponding to a video to be played is received, the application program window information is sent to the three-dimensional video service component, so that the three-dimensional video service component determines whether application software corresponding to the application program window information supports 3D display or not according to the application program window information; if the application software supports 3D display, the window synthesis manager determines a preprocessed image corresponding to each frame image in the video to be played, combines the preprocessed image with the received interweaving parameter information together for arranging the images to obtain the image to be interwoven corresponding to the preprocessed image; when the images to be interlaced are displayed by the 3D display device, interlaced images corresponding to each frame of image are obtained, and all the interlaced images are sequentially played to enable the video to be played to be displayed in a 3D mode, so that the technical problem that in the prior art, three-dimensional display of the video or the images can be achieved only by using playing software of a system, or three-dimensional display of third-party playing software can be achieved only by modifying player program codes is solved, 3D display of the video played by the third-party playing software can be achieved without modifying the program codes of the playing software, and the universality of the 3D display of the video and the technical effects of user experience are improved.
Example two
When processing an image corresponding to each frame of video in a video to be played, whether the format of the image is the same as a preset image format or not can be judged in advance, and if the format of the image is different from the preset image format, the image needs to be processed first to obtain a preprocessed image. As illustrated in fig. 2, the method of the embodiment of the present invention includes:
s210, supporting 3D display by application software.
It should be noted that, for the method for determining whether the software supports 3D display and the specific implementation, reference may be made to example one. And determining that the application software for playing the video or the image supports 3D display according to the application program window information.
S220, judging whether the format of each frame of image corresponding to the video to be played is the same as a preset format or not; if yes, go to S230; if not, S240 is executed.
After determining that the application software supports 3D display, the window composition manager may pre-process whether the image is the same as a preset format. The pre-processing image is an image corresponding to each frame of video in the video to be played.
It should be noted that, if the pre-processed image is to be displayed in 3D, not only a corresponding 3D display device is required, but also the format of the image to be pre-processed is required to be ensured to be the same as the preset image format. This is because: if the preprocessed image is a two-dimensional image only, 3D display cannot be achieved even if the interleaving parameter information is determined, and therefore, before the image is subjected to the layout processing, it may be determined whether the format of the preprocessed image satisfies the preset format.
The preset image format can be one or more of a left-right format, a top-bottom format or a nine-square format, and a user can determine the preset format according to actual conditions or the frequent degree of image processing.
If the acquired preprocessed image has the same format as the preset image, the image corresponding to each frame of video may be used as the preprocessed image, that is, S230 is executed; if the pre-processed image is different from the preset format, the image corresponding to each frame of video obtained at this time is used as the image to be processed, and the image to be processed is processed to obtain the pre-processed image with the same preset format, that is, S240 is executed.
And S230, taking each frame of image of the video to be played as a preprocessing image.
The preset format can be a left-right format, a top-bottom format and a nine-square format. If the image corresponding to each frame of video in the video to be played is in the left-right format, the image corresponding to each frame of video can be used as a pre-processing image.
For example, the preset format is the three formats, and if the acquired preprocessed images are both left and right format images, it is determined that the preprocessed images are the same as the preset format, and an image corresponding to each frame of video is used as the preprocessed image.
S240, processing the image to be processed by adopting a preset processing mode to obtain a preprocessed image with the same format as the preset format.
That is, the image corresponding to each frame of video in the video to be played is different from the preset format, and the image obtained at this time is called as the image to be processed. The image to be processed may be processed to the same format as one of the preset formats using a series of algorithms or pre-established models. If the image to be processed is a two-dimensional image, when the two-dimensional image is displayed on a 3D display device, the arrangement position of each pixel point cannot be determined even if there is an interleaving parameter, and thus the image seen by the user is also blurred.
In this embodiment, an image different from a preset format may be processed in advance to obtain an image to be processed. Illustratively, the image to be processed is a two-dimensional image, and AI intelligence may be adopted, or the two-dimensional image is processed by a preset algorithm, so that the processed image is consistent with a preset format, that is, the image is preprocessed.
That is, if the image corresponding to each frame of video in the video to be played is the same as the preset format, the image may be referred to as a preprocessed image; if the formats are different, the image to be processed is called as an image to be processed, and the image to be processed is processed to obtain a preprocessed image with the same format as the preset format.
And S250, a re-arranging module in the window synthesis manager arranges the pre-processed image according to the received interleaving parameter information. The window synthesis manager has a rearrangement module, and the rearrangement module needs to use the interleaving parameter information sent by the interleaving parameter module to realize the rearrangement function.
The window composition management may schedule the re-mapping module when receiving a message sent by the three-dimensional video service component. And the re-arranging module can determine the position of each pixel point of the preprocessed image when the pixel point is displayed on the display device according to the received interweaving parameter information.
Optionally, according to the preprocessed image and the interleaving parameter information, rearranging each pixel point in the preprocessed image, so that when the pixel points respectively arranged in odd columns and even columns are displayed on the display device, the pixel points respectively enter the left-eye window synthesis manager and the right-eye window synthesis manager of the user, and the arranged image can be stored in the storage space corresponding to the screen. And displaying the 3D video on a window after the interleaved rendering so that a user can see the 3D video.
It can be understood that: the re-mapping module is used for determining the position of each pixel point when the preprocessed image is displayed on the display device according to the received interweaving parameter information. Finally, after the pixels in the odd columns or the even columns which are respectively arranged are interlaced through the 3D display device, the pixels can respectively enter the left eye and the right eye or the right eye and the left eye of a user, and then a 3D view is formed in the brain of the user. And sequentially displaying the images to be interlaced through a 3D display device to obtain 3D display of the video.
On the basis of the above technical solution, it should be noted that, when 3D display is performed on a video, the operation mode of the display screen needs to be adjusted to the 3D display mode.
According to the technical scheme of the embodiment of the invention, when application program window information corresponding to a video to be played is received, the application program window information is sent to the three-dimensional video service component, so that the three-dimensional video service component determines whether application software corresponding to the application program window information supports 3D display or not according to the application program window information; if the application software supports 3D display, the window synthesis manager determines a preprocessed image corresponding to each frame image in the video to be played, combines the preprocessed image with the received interweaving parameter information together for arranging the images to obtain the image to be interwoven corresponding to the preprocessed image; when the images to be interlaced are displayed by the 3D display device, interlaced images corresponding to each frame of image are obtained, and all the interlaced images are sequentially played to enable the video to be played to be displayed in a 3D mode, so that the technical problem that in the prior art, three-dimensional display of the video or the images can be achieved only by using playing software of a system, or three-dimensional display of third-party playing software can be achieved only by modifying player program codes is solved, 3D display of the video played by the third-party playing software can be achieved without modifying the program codes of the playing software, and the universality of the 3D display of the video and the technical effects of user experience are improved.
EXAMPLE III
As a preferred embodiment of the foregoing embodiment, as illustrated in fig. 3, the method according to the embodiment of the present invention includes:
s301, image or video playback starts.
When a button for video playback or image playback is triggered, application window information corresponding to a playback window may be determined and sent to the window composition manager. The application window information carries an identifier corresponding to the playing software and a number or an ID corresponding to the window. The advantage of sending the application window information to the window composition manager is that when the re-layout module in the window composition manager performs the layout processing on the image, it can determine which window the currently processed video image corresponds to, and determine through which window the image to be interleaved is played after the processing is completed.
S302, judging whether a player playing the images or videos supports 3D display, and if so, executing S303; if not, executing S304.
The window synthesis manager receives application program window information and sends the application program window information to the three-dimensional video service assembly to determine whether application software corresponding to the window, namely playing software supports 3D display or not, namely whether the application software is in a pre-stored white list or not is determined according to a playing software identifier carried in the application program window information. If the software is in the white list, the software supports 3D display, and S303 is executed; if the software is not in the white list, it indicates that the software does not support 3D display, and step S304 is executed.
And S303, displaying and triggering the 3D switching button, and sending the interleaving parameter information to the window synthesis manager by the three-dimensional video service component.
If the software supports 3D display, a 3D switch button may pop up on the window, and the switch button may be used to switch the display interface to 3D display. At this time, the window composition manager may receive the interleaving parameter information and invoke the built-in rearrangement module.
It should be noted that the sending of the interleaving parameter information is performed by the interleaving information parameter generating module. The interleaving parameter generating module can be arranged in the three-dimensional video service component, and can also be arranged in an operating system as an independent module. The interleaving parameter generation module only needs to send interleaving parameter information to the window synthesis manager.
And S304, not displaying the 3D switching button.
If the playing software does not support 3D display, a switching button for judging whether to perform 3D display or not can not be popped up on the display interface.
Note that, at this time, the user may switch the display screen to the 2D display mode. Of course, if the 3D display is supported, the user may switch the display screen to the 3D display mode.
S305, the window composition manager rearranges the display window of the video or image to be played and displays the video or image.
The window composition manager may receive interleaving parameter information. And determining a mode for arranging each pixel point of the preprocessed image according to the interweaving parameter information.
