Change.
Certainly, in some embodiments, user also can choose close screen capture Optimizing Mode, with directly to wearing it is aobvious
Show that the 3D rendering shown on device screen carries out the operations such as screenshotss, record screen and throwing screen, the screen capture adapted under special scenes needs
It wants.
Step S102 generates corresponding screen capture file according to the original image in response to specifying trigger action.Its
In, the specified trigger action includes screenshotss trigger action, record screen trigger action and throwing screen trigger action.
After system judgement enters screen capture Optimizing Mode, the specified trigger action of user is detected, when detecting specified touching
When hair operation occurs, in response to specifying the generation of trigger action, generated according to the original image obtained in previous step corresponding
Screen capture file.Here original image is image corresponding with the 3D rendering that shows in display device screen is worn, note: 3D
Image is obtained after handling according to the requirement for wearing display equipment 3D display effect original image, and 3D rendering includes left and right point
Two images of screen, 3D rendering is there are certain distortion, and original image is worn in display equipment using (for example game is answered
With, Video Applications) the original 2D image that generates.
Specified trigger action includes one of screenshotss, record screen and throwing screen or a variety of, that is to say, that the embodiment of the present application branch
A variety of screen capture application scenarios are held, it is versatile.Record screen and the difference of screenshotss are that screenshotss are to the screen on a time point
Image is intercepted, and recording screen is to showing on (such as 5 seconds, record screen has starting and end time) screen in a period of time
Each video frame shown record and is saved into video flowing.Throwing screen is then each video frame real-time delivery for will showing on screen to another
It is played out in terminal.Unlike screenshotss in the prior art, record screen and throwing screen, the embodiment of the present application is not direct enemy
The screen picture for wearing display equipment is acquired, but generates screen capture file according to the corresponding original image of screen picture.
As shown in Figure 1 it is found that the screen capture method for wearing display equipment of the embodiment of the present application, solves and wear display
Equipment screenshotss/record screen/subsequent display effect of throwing screen file is poor, the bad problem of user experience, supports screenshotss/record screen/throwing screen etc.
Plurality of application scenes, it is versatile.And use is worn original image generation screen corresponding with 3D rendering in display equipment and is adopted
Collect file, is theoretically obtainable the lossless process of content, display effect is more preferable, while being transformed into the mistake of 2D image without 3D
Journey, performance consumption are lower.
In view of the requirement of different application scene sub-screen acquisition file is different, for example the resolution ratio of image is required when screenshotss
Height, and resolution ratio can be lower when record screen, direct basis original image generates corresponding screen capture file and although can be avoided
The problem of acquisition 3D rendering leads to subsequent poor display effect, but not can be carried out picture editting, image procossing, in this regard, the application
Embodiment proposes creation virtual extended screen, and original image is output on virtual extended screen, based on virtual extended screen
Content generate screen capture file, and the parameter of virtual extended screen and the parameter of original image support it is customized, in this way

SDK processing.
The application for wearing display equipment is needed using specific SDK (Software Development Kit, software development
Kit) it is developed, what it is using generation is not the optical imagery for meeting HMD device requirement, and at this moment SDK can be to original image
Processing, which generates HMD, needs optical imagery to be shown, i.e. the 3D rendering of adaptation binocular, adaptation HMD device optical texture in Fig. 2.
Judge whether to need to process, is to be reprocessed according to function, is otherwise output on physical display screen.
For 3D rendering, it can generally be directly displayed on the physical screen for wearing display equipment, consider some particular fields
Scape, such as application render and carry out a game picture, normal flow be wear the picture of display game in display equipment, but if
Screen currently is being recorded, it would be possible that the interface element for needing currently recording screen in game picture superposition instruction is (such as common
Red spots) and the contents such as recording time, here it is reprocess 3D rendering according to function.
Referring to fig. 2, for original image, screenshotss/record screen/throwing screen trigger action is judged whether there is, is cut in no starting
It is without processing for performance consideration in the case where screen/record screen/screen projection function.
That is, not handled original image if specified trigger action is not detected.
The detection of trigger action is the function of wearing display equipment and have, and can be realized using the prior art, for example, user
Starting screenshotss function etc. is triggered by wearing the shortcut key triggering starting screenshotss function of display equipment, or by voice command, this
In do not do excessive explanation.
With continued reference to Fig. 2, when detecting specified trigger action, that is, when there is screenshotss/record screen/throwing screen trigger action, this
Application embodiment handles original image, and avoiding screenshotss file/record screen file/throwing screen file includes left and right split screen and presence
Fault image.
In one embodiment, in response to specifying trigger action, virtual extended screen, each original graph that will acquire are created
As being output on the virtual extended screen, based on the content of the virtual extended screen, corresponding screen capture file is generated.
Here in response to specify trigger action, creation virtual extended screen include: in response to the screenshotss trigger action,
One or more of the record screen trigger action and throwing screen trigger action, create at least one virtual extended screen.
Referring to fig. 2, a virtual extended screen is created according to functional requirement (that is, screenshotss/record screen/throwing screen functional requirement)
Curtain, and original image is processed as needed, it is output on virtual extended screen.Such as when screenshotss, user wishes
To clearly image, then screen and image parameter can be arranged it is finer, and in user wishes when recording screen and throwing screen
Appearance is smooth, can shield and throw the smaller of parameter (resolution ratio) setting shielded record, to guarantee that fluency is more preferable.
Followed by the content based on the virtual extended screen, corresponding screen capture file is generated, comprising: will be described
The content of virtual extended screen is encoded, and the corresponding image file of screenshotss trigger action is generated, or, generating record screen triggering behaviour
Work/corresponding the video file of throwing screen trigger action.That is, corresponding record screen function, by virtual extended screen research content at video flowing
Form output is saved into video file.Virtual extended screen content is carried out coding and saved into image file by corresponding screenshotss function.It is right
Screen projection function is answered, virtual extended screen research content is saved at video into video file.
It should be noted that the present embodiment can be corresponding according to specifically needing the content to virtual extended screen to carry out
Processing, neither influence user watches 3D content by physical display screen, and available screenshotss/record screen/throwing screen display effect is more
Good file.
It is aforementioned to be carried out with compatible screenshotss/record screen/screen projection function simultaneously, and only for one virtual extended screen of creation
Explanation.In this case, the video frame and throw the size for the video frame that screen obtains, lattice that screenshotss obtain image, record screen obtain
Formula etc. is identical.Screenshotss/record screen/three kinds of throwing screen function shares many treatment processes, therefore reduces the performance consumption of system.
Certainly, if screenshotss/requirement difference of the record screen/throwing screen to image is larger, muti-piece virtual extended screen can also be created
The processing that curtain is distinguished.That is, in response to specifying trigger action, creating virtual extended in embodiments herein
Screen includes: in response to the screenshotss trigger action, according to the creation of screenshotss parameter and the screenshotss parameter from screenshotss application
The virtual extended screen of adaptation；Or, in response to the record shield trigger action, according to from record screen application recording parameter creation with
The virtual extended screen for recording parameter adaptation；Or, shielding trigger action in response to the throwing, according to from the throwing for throwing screen application
Shield parameter creation and the virtual extended screen for throwing screen parameter adaptation；Wherein, throwing screen parameter be based on current network state,
It is determined wait throw the data volume of screen content, the resolution ratio for being thrown screen end, thrown at least one of the screen proportion at screen end information.
In one embodiment, if currently detected screenshotss trigger actions, according to screenshotss trigger action, creation with
(the virtual extended screen of the application has resolution ratio category to first virtual extended screen of screenshotss parameter (such as resolution ratio) adaptation
Property, user can be with the attribute value of custom resolution to adapt to different demands), it is virtual that the original image that will acquire is output to first
In extended screen, the subsequent first virtual extended screen that is based on generates screenshotss image.If currently detected screenshotss trigger actions
Shield trigger action with record, then it is virtual to create first be adapted to screenshotss parameter (such as resolution ratio) according to screenshotss trigger action
Extended screen, the original image that will acquire are output on the second virtual extended screen, subsequent to be based on the life of the first virtual extended screen
Shield trigger action at screenshotss image, and according to record, creates the second virtual extended being adapted to record screen parameter (such as resolution ratio)
Screen, the original image that will acquire are output on the second virtual extended screen, and the subsequent second virtual extended screen that is based on generates record
Shield video data.
In this way, being handled respectively screenshotss and record screen, for screenshotss function, relatively sharp image can be exported, for record
Shield function, can export that clarity is low but video is shielded in the smaller record of small the occupancys memory space of data volume, it is each to meet different function
From demand.Therefore, the favorable expandability of the present embodiment.
It wears and screenshotss application, the application of record screen is installed in display equipment and throw screen application, include setting in advance in screenshotss application
The screenshotss parameter set, such as clarity, size these parameters of screenshotss image also include presetting in same record screen application
Record screen parameter, throw screen application in also include throw screen parameter.Screen is thrown to be a difference in that applied to what the application of record screen and screenshotss were applied
Throwing screen is to record and play the operating process that real-time is high, has compatibility requirements to receiving device, therefore throw screen parameter and be based on working as
At least one of preceding network state, the data volume wait throw screen content, the resolution ratio for being thrown screen end, the screen proportion for being thrown screen end
Information determines.The present embodiment by improve parameter come optimize throw screen effect, such as according to network state, amount of content data, thrown
Shield the resolution ratio at end, thrown the best parameters of dynamic selects such as the screen proportion for shielding end to meet throwing screen demand.For example, due to electricity
Different depending on the screen proportion of itself, the 3D picture for wearing display equipment cannot stretch, and otherwise easy ratio is not right, lead to user's body
Test difference.The present embodiment by modification virtual extended screen parameter and output video flowing parameter, ensure that throwing screen content with
Tv aspect ratio adaptation improves throwing screen effect directly with the output of parameter needed for TV.For another example, present mobile phone or
It wears when display equipment throws screen and the slack situation of Caton often occurs, this programme can optimize this problem, according to current
Network state, if network communication status well if improve the clarity of video and reduce the clear of video if network state is poor
Clear degree, these can be realized by modifying the parameter of the parameter of virtual extended screen and the video flowing of output.
In the present embodiment, it includes: to described that each original image that will acquire, which is output on the virtual extended screen,
Original image is output on the virtual extended screen after carrying out cutting processing；Or, the original image described in the multiframe of acquisition into
Row screening, each original image filtered out is output on the virtual extended screen.
That is, after getting original image, according to screenshotss apply in parameter request original image is carried out
It cuts, the original image after cutting is output on virtual extended screen, image processing requirements are met.In addition, carrying out record screen
When Deng operating, the image of acquisition can be screened, only the original image filtered out being output on virtual extended screen, is kept away
Having exempted from obtained record screen file includes the video content unrelated with target application, improves record screen effect.
It, should in the present embodiment after each original image that will acquire is output on the virtual extended screen
Method further include: be embedded in watermarking images on each original image, obtain the content of the virtual extended screen.Add watermark
It is that is conducive to by identification and is cut for the screenshotss file, record screen file or throwing screen file progress uniqueness label for wearing display equipment generation
The source for shielding the screen captures files such as file, avoids dispute.
Hereafter explanation wears the screen capture process for showing equipment for recording the realization of screen function:
Operation 3D application in display equipment is worn, the image of 3D application is shown on wearing display device screen.
User triggers record screen function, and system shields function trigger event in response to record, creates one piece of virtual extended screen.
The red dot of the image superposition instruction record screen state of 3D application and record screen time are (that is, carry out content seen in user
Transformation) after be shown in and wear in display device screen.
Original image (image of non-adaptation binocular) is output to virtual extended screen.
It is emphasized that being that original image is output to virtual extended screen here, so being that no user is wearing
The instruction record screen state red dot seen in display equipment and record screen these interface elements of time, because these information are literary in record screen
Nonsensical in part, therefore, the user experience of the embodiment of the present application is more preferable.
The content of virtual extended screen is carried out to be encoded into video file.
Can be with customized video parameter while coding, while this virtual extended screen can also be used to screenshot, this
Sample flexibility is more preferable, and performance consumption is also small.And end processing sequences when record screen can be reduced.For example, during record screen, no
Wish recorded video start or at the end of picture, then directly can be arranged and sentence to current picture in record screen function
Disconnected, if current picture is not the picture of target 3D application (such as game application), these images are not output to virtually by control
Extended screen goes modification record screen file, problem complicated for operation so as to avoid recording again later.
So far, the split screen distortion of 3D application is shown on the physical screen for wearing display equipment of the present embodiment and with record screen
The image of information；And recording the file that screen obtains is that monocular is undistorted, (can not need aobvious by wearing for user's direct viewing
Show equipment) image, do not record screen information, do not record that screen information is more reasonable, and experience is more preferable.
From the foregoing, it will be observed that the screen capture method for wearing display equipment of the embodiment of the present application, obtained record screen/screenshotss/throwing
The files such as screen can be for user's direct viewing, and display effect is more preferable, and solving record shielding to 3D rendering in the prior art causes
Poor user experience the problem of.Also, it can be compatible with simultaneously when screenshotss/record screen/screen projection function triggers simultaneously, i.e., it is compatible to cut
Plurality of application scenes, the versatilities such as screen/record screen/throwing screen are good；A virtual extended screen can only be created to complete this three screens and adopt
Collect function, the performance consumption of system is small, can also create the processing that muti-piece virtual screen is distinguished, favorable expandability.It is virtual to expand
The parameter support of the parameter and original image of opening up screen is customized, can balance in performance and effect, flexibility is stronger.
