Detailed Description
The technical scheme of the embodiment of the invention is suitable for the application scene of adjusting the display angle of the display page in the live broadcasting process. By adopting the technical scheme of the embodiment of the invention, the page angle can be adaptively adjusted in real time when the user rotates the terminal equipment, so that the user can freely change the angle of the terminal equipment on the premise of not influencing the normal angle display of the page.
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.
The embodiment of the invention discloses a method for adjusting a picture angle, which is applied to anchor terminal equipment and is shown in figure 1, and the method comprises the following steps:
s101, obtaining first rotation angle information, wherein the first rotation angle information is information representing that the anchor terminal equipment rotates by a first angle along a first direction;
specifically, the obtaining of the first rotation angle information needs to be implemented by matching a gravity sensor of the anchor end device, that is, when the anchor rotates the anchor end device by an angle, the gravity sensor of the anchor end device senses and calculates the rotation angle and the direction of the anchor end device, and outputs the calculated rotation angle and direction, that is, outputs the first rotation angle information. It can be understood that, in the embodiment of the present invention, the rotation direction and the rotation angle information when the anchor adjusts the angle of the anchor device may be obtained by receiving the first rotation angle information sent by the gravity sensor of the anchor device.
And S102, rotating the display picture by a first angle along the direction opposite to the first direction according to the first rotation angle information.
Specifically, when the anchor terminal device senses that the angle of the anchor terminal device is rotated, if the angle of the displayed picture is not rotated, the displayed picture is also rotated along with the rotation of the anchor terminal device. For example, assume that the anchor at the initial time is to live a mobile phone in a vertical screen state, and when the anchor changes the mobile phone from a counterclockwise rotation of 90 degrees to a horizontal screen state for live broadcasting, because the existing live APP defaults to collect images in a vertical screen mode and perform stream pushing, if the display screen of the anchor terminal device is not processed, the screen displayed by the anchor terminal device is also the screen rotated counterclockwise by 90 degrees. Then the viewed picture is rotated 90 degrees counterclockwise for the anchor, and the inverted picture severely affects the anchor viewing.
In order to solve the above problem, an embodiment of the present invention sets that, when the first rotation angle information of the anchor device is acquired, the display screen of the anchor device is rotated by a first angle in a direction opposite to the first rotation direction, so that the display screen of the anchor device is adjusted to be displayed at a normal angle. Still by way of example, it is assumed that the anchor at the initial moment performs live broadcast in a vertical screen state of the mobile phone, and when the anchor changes from a counterclockwise rotation of 90 degrees to a horizontal screen state for direct broadcast, the display picture of the anchor terminal device will also rotate counterclockwise by 90 degrees in synchronization, at this time, the embodiment of the present invention rotates the display picture of the anchor terminal device by 90 degrees in a clockwise direction and displays the display picture, so that the picture displayed by the anchor terminal device is normal, and the picture displayed by the anchor terminal device at a vertical 90 degrees is consistent with the state of the anchor, which is convenient for the anchor to watch.
As can be seen from the above description, according to the technical scheme of the embodiment of the present invention, the angle of the display image is adaptively adjusted by recognizing the rotation of the user to the terminal and according to the rotation direction and angle of the user to rotate the terminal, so that the anchor can view the image at a comfortable angle. Based on the above scheme, the anchor can freely adjust the angle of the terminal equipment in the live broadcast process, and normal watching of the anchor is not influenced, so that the user experience is favorably improved.
The embodiment of the invention also discloses another method for adjusting the angle of the picture, which is applied to the equipment at the audience end and is shown in figure 2, and the method comprises the following steps:
s201, receiving a display picture pushed by anchor terminal equipment, and displaying the display picture; the angle for displaying the display picture is the same as the angle for displaying the display picture by the anchor terminal equipment;
specifically, when the audience equipment watches the anchor live broadcast through the live broadcast APP, the received picture is a display picture which is processed by the anchor equipment and pushed by the server. It can be understood that the picture displayed by the viewer side device is the same picture as the picture displayed on the main player side device, including the display angle. If the anchor terminal device is in a landscape state, the picture displayed by the anchor terminal device is the picture displayed in the landscape after the processing of the technical scheme of the embodiment of the invention. Correspondingly, after the picture is pushed to the audience equipment, the audience equipment displays the contents displayed on the horizontal screen no matter at what angle.
S202, obtaining second rotation angle information, wherein the second rotation angle information is information representing that the equipment rotates by a second angle along a second direction;
specifically, after the angle of the displayed picture is changed due to the rotation of the anchor device, the angle of the picture received and displayed by the viewer device is directly changed. At this time, the viewer may need to adjust the angle of the viewer-side device, such as a mobile phone, a tablet computer, etc., to adjust the screen angle.
The second rotation angle information indicates that the viewer rotates the viewer-side device by a second angle along a second direction. For example, if the viewer rotates the mobile phone in the vertical screen state by 90 degrees counterclockwise to make the mobile phone in the horizontal screen state, the rotation may be represented as rotating by plus 90 degrees, and correspondingly, if the viewer rotates the mobile phone in the vertical screen state by 90 degrees clockwise to make the mobile phone in the horizontal screen state, the rotation may be represented as rotating by minus 90 degrees. In practical application of the technical scheme of the embodiment of the invention, the positive direction and the negative direction of rotation can be freely set.
And S203, rotating the display picture by a second angle along the same direction as the second direction according to the second rotation angle information.
Specifically, according to the functions of common smart devices such as a mobile phone and a tablet, when a user rotates the angle of the device, a display picture can be automatically changed to adapt to the size of a screen. For example, when the user rotates the mobile phone from the vertical screen state to the horizontal screen state, the mobile phone will automatically adjust the display to the horizontal screen display, that is, the display is rotated by the same angle relative to the reverse direction of the direction in which the user rotates the mobile phone. For example, if the user rotates the mobile phone from the vertical screen state by 90 degrees counterclockwise to the horizontal screen state, the display screen needs to be rotated by 90 degrees clockwise to implement horizontal screen playing, which is suitable for the user to watch.
Based on the above-mentioned self-function of the spectator end device, when the spectator rotates the spectator end device along the second direction by a second angle, the picture will rotate along the reverse direction of the second direction by the second angle. Since the picture displayed by the viewer-side device is the picture after the rotation of the anchor side, the display picture needs to be rotated by a second angle along the second direction, so that the picture can be fixed and can not be automatically rotated.
Through the introduction, when the angle of the image is changed due to the angle adjustment of the anchor terminal, the viewer terminal device can sense the device angle adjustment of the user for the image angle change, and performs adaptive angle adjustment on the image according to the angle adjustment, so that the viewer can obtain the image displayed at a normal angle after adjusting the angle of the device. The technical scheme allows the anchor end to freely rotate the angle of the equipment without influencing the watching experience of the audience.
It can be understood that when the anchor is live through live broadcast products, specifically live through live broadcast APPs, such as pepper live broadcast, YY live broadcast, etc., the dynamic picture of the anchor can be seen in real time at the audience. The method comprises the steps that the anchor terminal equipment collects scene images of an anchor and the environment where the anchor is located, the collected images are displayed on a display screen of the anchor terminal equipment, meanwhile, the anchor terminal equipment pushes the displayed image images to audience terminal equipment through a server to be displayed, and the image content displayed by the audience terminal equipment is the same as the image content displayed by the anchor terminal equipment.
It should be noted that, under a normal condition, after the anchor terminal device collects an image in a vertical screen manner to form a display screen, the image information is pushed to the audience terminal device at a vertical screen angle, that is, when the audience terminal device displays the received display screen in a vertical screen manner, the display screen is a normal display screen.
When the anchor adjusts the angle of the anchor terminal device by rotating the anchor terminal device, the anchor terminal device acquires the image in a vertical screen mode by default, so that if the display angle of the display picture is not adjusted, the angle of the display picture of the anchor terminal device can also rotate by the same angle along with the change of the angle of the anchor terminal device, and the anchor terminal device is inconvenient to watch.
In order to solve the above problem, when the anchor terminal rotates the anchor terminal device, the anchor terminal can still view the picture displayed at the normal angle. At this time, the picture displayed on the anchor terminal device has a certain angle difference with respect to the anchor terminal device itself, that is, the picture is not strictly displayed on the anchor terminal device in a vertical screen manner. And because the anchor terminal equipment pushes the display page in a vertical screen mode by default, when the anchor rotates the anchor terminal equipment to adjust the picture angle, the picture pushed to the audience terminal equipment also has the same angle adjustment, and the picture displayed on the audience terminal equipment has certain angle difference relative to the audience terminal equipment per se, namely, the picture is not strictly displayed on the audience terminal equipment in a vertical screen mode, and the audience needs to adjust the display picture to be displayed at a normal angle by adjusting the angle of the audience terminal equipment.
As can be understood from the above description, the method for adjusting the picture angle provided in the embodiment of the present invention is actually a technical solution that needs to perform picture angle adjustment on the anchor device and the viewer device, respectively, so that the anchor device and the viewer device can still display the picture at a normal angle under the condition of arbitrarily adjusting the angle. That is to say, the method for adjusting the picture angle shown in fig. 1 and the method for adjusting the picture angle shown in fig. 2 are technical solutions having a corresponding relationship, and in an actual implementation process, the method needs to be implemented in the anchor device and the viewer device respectively so as to simultaneously implement the adjustment of the picture angle, so that both the anchor device and the viewer device can normally display the picture.
In particular, since the live broadcast process needs to be implemented based on live broadcast products such as live broadcast APPs, the technical scheme provided by the embodiment of the present invention is a technical scheme applied to live broadcast products such as live broadcast APPs. The live APP needs to be installed and run on intelligent terminal equipment such as a mobile phone, and therefore the technical scheme of the embodiment of the invention is a technical scheme which is based on terminal equipment and applied to live APP.
Fig. 3 shows a specific implementation procedure of the technical solution combining the methods for adjusting the picture angle shown in fig. 1 and fig. 2. Referring to fig. 3, a method for adjusting a picture angle disclosed in the embodiment of the present invention specifically includes:
when the anchor is in live broadcasting, the anchor end equipment can be adjusted at will to put the angle such as a mobile phone, a tablet computer and the like, for example, the anchor end equipment can be adjusted from a vertical screen live broadcasting state to a horizontal screen live broadcasting state, or the anchor end equipment can be adjusted to any angle for live broadcasting.
When the anchor rotates the anchor terminal device to adjust the angle of the anchor terminal device, the anchor terminal device executes step S301 to obtain first rotation angle information;
specifically, the first rotation angle information indicates that the anchor rotates the anchor end device by a first angle in a first direction. For example, if the anchor rotates the mobile phone in the vertical screen state by 90 degrees counterclockwise to make the mobile phone in the landscape screen state, the rotation may be represented as rotating by plus 90 degrees, and correspondingly, if the anchor rotates the mobile phone in the vertical screen state by 90 degrees clockwise to make the mobile phone in the landscape screen state, the rotation may be represented as rotating by minus 90 degrees. In practical application of the technical scheme of the embodiment of the invention, the positive direction and the negative direction of rotation can be freely set.
The obtaining of the first rotation angle information needs to be realized by matching a gravity sensor of the anchor end device, that is, when the anchor rotates the anchor end device by an angle, the gravity sensor of the anchor end device senses and calculates the rotation angle and the direction of the anchor end device, and outputs the calculated rotation angle and direction, that is, outputs the first rotation angle information. It can be understood that, in the embodiment of the present invention, the rotation direction and the rotation angle information when the anchor adjusts the angle of the anchor device may be obtained by receiving the first rotation angle information sent by the gravity sensor of the anchor device.
For example, when the technical solution of the embodiment of the present invention is applied to an IOS system device, the UIViewControllerRotation class inside the IOS system may detect a gravity change condition of the device by using a gravity sensor of the IOS device, and when receiving a notification of device rotation sent by the gravity sensor, calculate an angle and a direction of the current device rotation.
S302, the anchor terminal equipment rotates the display picture by a first angle along the direction opposite to the first rotation direction according to the acquired first rotation angle information;
specifically, when the anchor terminal device senses that the angle of the anchor terminal device is rotated, if the angle of the displayed picture is not rotated, the displayed picture is also rotated along with the rotation of the anchor terminal device. For example, assume that the anchor at the initial time is to live a mobile phone in a vertical screen state, and when the anchor changes the mobile phone from a counterclockwise rotation of 90 degrees to a horizontal screen state for live broadcasting, because the existing live APP defaults to collect images in a vertical screen mode and perform stream pushing, if the display screen of the anchor terminal device is not processed, the screen displayed by the anchor terminal device is also the screen rotated counterclockwise by 90 degrees. Then the viewed picture is rotated 90 degrees counterclockwise for the anchor, and the inverted picture severely affects the anchor viewing.
In order to solve the above problem, an embodiment of the present invention sets that, when the first rotation angle information of the anchor device is acquired, the display screen of the anchor device is rotated by a first angle in a direction opposite to the first rotation direction, so that the display screen of the anchor device is adjusted to be displayed at a normal angle. Still by way of example, it is assumed that the anchor at the initial moment performs live broadcast in a vertical screen state of the mobile phone, and when the anchor changes from a counterclockwise rotation of 90 degrees to a horizontal screen state for direct broadcast, the display picture of the anchor terminal device will also rotate counterclockwise by 90 degrees in synchronization, at this time, the embodiment of the present invention rotates the display picture of the anchor terminal device by 90 degrees in a clockwise direction and displays the display picture, so that the picture displayed by the anchor terminal device is normal, and the picture displayed by the anchor terminal device at a vertical 90 degrees is consistent with the state of the anchor, which is convenient for the anchor to watch.
The first rotation direction may be any rotation direction in a plane where a display screen of the anchor device is located, and the first angle may be an angle of any size. The above steps S301 and S302 are real-time processing procedures, that is, in the process of the anchor live broadcast, as long as the action of rotating the angle of the anchor device is executed, the anchor device immediately executes the above steps S301 and S302 to adjust the angle of the display screen, so that the anchor can arbitrarily adjust the angle of the anchor device without affecting the display angle of the screen without any perception.
S303, the anchor terminal equipment pushes the rotated display picture to audience terminal equipment;
specifically, if the anchor terminal device collects images in a vertical screen state, the images collected in the vertical screen state are directly displayed on the anchor terminal device, and meanwhile, a display picture is pushed to the audience terminal device. If the anchor terminal device does not acquire the image in the vertical screen state, that is, the anchor terminal device rotates by a certain angle, according to the technical scheme of the embodiment of the invention, the anchor terminal device adjusts the display picture of the anchor terminal device by the same angle in the reverse direction and then displays the adjusted display picture. However, the live APP is pushed in a vertical screen mode by default, so that the display image which is pushed to the viewer side and is adjusted by the same angle in the reverse direction is displayed.
For example, assuming that the anchor at the initial moment is to live the mobile phone in a vertical screen state, when the anchor changes the mobile phone from a counterclockwise rotation of 90 degrees to a horizontal screen state for live broadcasting, the display screen of the anchor device is also rotated by 90 degrees counterclockwise in synchronization, and at this time, according to the processing of the technical scheme of the embodiment of the present invention, the display screen of the anchor device is rotated by 90 degrees clockwise and displayed. Accordingly, the picture pushed to the viewer is also the picture rotated by 90 degrees in the counterclockwise direction.
It should be noted that the anchor device pushes the display image or the rotated display image to the viewer device, and actually, the display image is first sent to the server, and then the display image is pushed to the viewer device by the server in a broadcast manner. The server only plays a role of routing forwarding and does not process the live broadcast picture.
S304, receiving a display picture pushed by the anchor terminal equipment by the audience terminal equipment, and displaying the display picture;
specifically, when the audience equipment watches the anchor live broadcast through the live broadcast APP, the received picture is a display picture which is processed by the anchor equipment and pushed by the server. It can be understood that the picture displayed by the viewer side device is the same picture as the picture displayed on the main player side device, including the display angle. If the anchor terminal device is in a landscape state, the picture displayed by the anchor terminal device is the picture displayed in the landscape after the processing of the technical scheme of the embodiment of the invention. Correspondingly, after the picture is pushed to the audience equipment, the audience equipment displays the contents displayed on the horizontal screen no matter at what angle.
For example, if the anchor adjusts the mobile phone from a vertical screen state to a landscape screen state by rotating 90 degrees counterclockwise, the embodiment of the present invention rotates the picture displayed by the anchor device 90 degrees clockwise, so that the picture is suitable for being viewed on the landscape screen, and then pushes the rotated picture to the viewer device. At this time, the picture received by the viewer-side device is a picture rotated by 90 degrees clockwise, and even if the viewer-side device is in a vertical screen state, the displayed picture is a picture rotated by 90 degrees clockwise.
S305, acquiring second rotation angle information; the second rotation angle information is information representing that the equipment rotates by a second angle along a second direction;
specifically, after the angle of the displayed picture is changed due to the rotation of the anchor device, the angle of the picture received and displayed by the viewer device is directly changed. At this time, the viewer may need to adjust the angle of the viewer-side device, such as a mobile phone, a tablet computer, etc., to adjust the screen angle.
The second rotation angle information indicates that the viewer rotates the viewer-side device by a second angle along a second direction. For example, if the viewer rotates the mobile phone in the vertical screen state by 90 degrees counterclockwise to make the mobile phone in the horizontal screen state, the rotation may be represented as rotating by plus 90 degrees, and correspondingly, if the viewer rotates the mobile phone in the vertical screen state by 90 degrees clockwise to make the mobile phone in the horizontal screen state, the rotation may be represented as rotating by minus 90 degrees. In practical application of the technical scheme of the embodiment of the invention, the positive direction and the negative direction of rotation can be freely set.
Similarly, the obtaining of the second rotation angle information needs to be implemented by matching a gravity sensor of the viewer-side device, that is, when the viewer rotates the angle of the viewer-side device, the gravity sensor of the viewer-side device senses and calculates the rotation angle and the direction of the viewer-side device, and outputs the calculated rotation angle and direction, that is, outputs the second rotation angle information. It can be understood that, in the embodiment of the present invention, the rotation direction and the rotation angle information when the angle of the viewer-side device is adjusted by the viewer may be obtained by receiving the second rotation angle information sent by the gravity sensor of the viewer-side device.
S306, according to the second rotation angle information, rotating the display picture by a second angle along the same direction as the second direction.
Specifically, according to the functions of common smart devices such as a mobile phone and a tablet, when a user rotates the angle of the device, a display picture can be automatically changed to adapt to the size of a screen. For example, when the user rotates the mobile phone from the vertical screen state to the horizontal screen state, the mobile phone will automatically adjust the display to the horizontal screen display, that is, the display is rotated by the same angle relative to the reverse direction of the direction in which the user rotates the mobile phone. For example, if the user rotates the mobile phone from the vertical screen state by 90 degrees counterclockwise to the horizontal screen state, the display screen needs to be rotated by 90 degrees clockwise to implement horizontal screen playing, which is suitable for the user to watch.
Based on the above-mentioned self-function of the spectator end device, when the spectator rotates the spectator end device along the second direction by a second angle, the picture will rotate along the reverse direction of the second direction by the second angle. Since the picture displayed by the viewer-side device is the picture after the rotation of the anchor side, the display picture needs to be rotated by a second angle along the second direction, so that the picture can be fixed and can not be automatically rotated.
For example, if in the live broadcasting process, the anchor rotates the mobile phone from the vertical screen state to the horizontal screen state by 90 degrees counterclockwise, the embodiment of the present invention simultaneously rotates the display screen by 90 degrees clockwise, and pushes the display screen to the viewer side device. At this time, the picture seen by the viewer-side device in the vertical screen state is a picture rotated by 90 degrees clockwise. In order to obtain a proper viewing angle, the viewer needs to rotate the mobile phone by 90 degrees in the counterclockwise direction so as to adjust the picture to a picture at a normal angle, but since the mobile phone has a function of adjusting the picture angle according to the rotation of the mobile phone, the mobile phone can rotate the picture by 90 degrees in the clockwise direction, and the obtained picture is still a picture rotated by 90 degrees in the clockwise direction, and is still not suitable for viewing.
In order to solve the problem, when the user rotates the mobile phone, the embodiment of the invention simultaneously rotates the picture in the same direction and at the same angle as the direction of the mobile phone rotated by the user so as to counteract the rotation of the display picture with the self-contained function of the mobile phone. Still by way of example, when the user rotates the mobile phone by 90 degrees in the counterclockwise direction to adjust the picture to the picture at the normal angle, the mobile phone may rotate the picture by 90 degrees in the clockwise direction due to the function of adjusting the picture angle according to the rotation of the mobile phone, and at this time, the embodiment of the present invention performs the rotation of 90 degrees in the clockwise direction on the picture, that is, performs the same rotation as the rotation of the mobile phone, so that the obtained picture is the picture at the normal angle, and is suitable for the audience to watch.
As can be seen from the above description, according to the technical solution of the embodiment of the present invention, by identifying the rotation of the terminal by the user, and according to the rotation direction and angle of the terminal rotated by the user, the angle of the display image is adaptively adjusted, so that both the anchor side and the viewer side can view the image at a comfortable angle. Based on the scheme, the anchor can freely adjust the angle of the terminal equipment in the live broadcasting process, and the normal watching of the anchor and audiences cannot be influenced.
