Fig. 3 shows a flowchart of a screen projection control method applied to a terminal device according to an embodiment of the present application, where the method includes:
301. in the screen projection process, if the shielding operation of the display screen is detected, the shielding area information of the display screen is determined;
the screen projection is a process of sending the current display content of the display screen of the terminal device to the screen projection device and displaying the current display content on the screen of the screen projection device. In the screen projection process, if the terminal device detects a display screen shielding operation (for example, a part of or all of the area of the display screen of the terminal device is shielded by a hand or other objects), the shielding area information of the display screen is determined and generated, and the shielding area information of the display screen is used for determining the position of the shielded area on the display screen, and may be information such as position coordinates. Specifically, a camera, a photoelectric screen, a floating screen, or other devices may be used to detect whether the display screen of the terminal device is shielded and the position of the shielded area.
302. And sending the information of the shielding area of the display screen to a screen projection device so as to indicate the screen projection device to shield the display content of the area corresponding to the display screen of the screen projection device according to the information of the shielding area of the display screen.
After determining the information of the shielding area of the display screen, the terminal device sends the part of information to the screen projection device to indicate the screen projection device to determine the corresponding area to be shielded according to the part of information, so that the display content of the corresponding area on the display screen of the screen projection device is shielded, and the leakage of user privacy information is prevented. And the corresponding area is an area corresponding to the information of the display screen shielding area. After receiving the information of the display screen shielding area sent by the terminal device, the screen projection device can determine the area which needs to be shielded on the display screen of the screen projection device according to the information of the position coordinates and the like contained in the information, and then shield the display content of the area by adopting a preset mode. For example, after the display area of the private information needing to be blocked is determined, a window capable of blocking the display content can be constructed, and the window is covered on the display area of the private information, so that the private information can be blocked, and the private information is effectively prevented from being leaked.
Further, the determining of the display screen occlusion region information may include:
determining coordinate information of a display screen shielding area;
correspondingly, sending the information of the display screen occlusion area to the screen projection device may include:
and sending the coordinate information of the display screen shielding area to the screen projection equipment.
When a user places a hand or other shielding object on a touch screen, a suspension screen or a photoelectric screen of the terminal device, the position of the hand or other shielding object can be sensed by the device, and coordinate information of a shielding area of the display screen can be determined. After the terminal device detects the position of the shielding object, the terminal device calculates the mapping coordinates to obtain coordinate information, and then can send a screen shielding instruction carrying the coordinate information to the screen projection device. After receiving the screen shielding instruction, the screen projection equipment analyzes the screen shielding instruction to obtain coordinate information, determines a corresponding area to be shielded according to the coordinate information, and shields the display content of the corresponding area.
Further, after step 302, the method may further include:
(1) if the display screen shielding operation is detected to be finished, counting the shielding duration of the display screen of the terminal equipment;
(2) determining the duration of the screen shielding of the screen projection equipment according to the duration;
(3) and after the duration time is up, sending an occlusion elimination instruction to the screen projection equipment to instruct the screen projection equipment to stop occluding the display content of the corresponding area.
For example, the user manually shields the display screen of the terminal device for a certain time period T1The terminal device can be based on the duration T1Determining the duration T of the screen shading of the screen projection equipment2Preferably set to T2>T1. Waiting time T2After the screen projection display is started, the terminal equipment can send a shielding elimination instruction to the screen projection equipment, and the screen projection equipment is controlled to stop shielding the display content of the corresponding area so as to recover normal screen projection display work. At the duration T2In addition, the user can close the privacy information popped up on the terminal equipment in time, so that the privacy information is prevented from being leaked. In addition, the screen shielding of the screen projection device can be eliminated in a manner of manual control by a user, that is, after the user manually closes the privacy information popped up on the terminal device, the user can operate on the terminal device to send a shielding elimination instruction to the screen projection device, and control the screen projection device to stop shielding the display content of the corresponding area.
In the screen projection process, if the terminal device detects the shielding operation of the display screen, the shielding area information of the display screen is determined according to the shielding operation, and the shielding area information of the display screen is sent to the screen projection device; after receiving the information of the display screen shielding area, the screen projection equipment can shield the display content of the area corresponding to the information of the display screen shielding area in the display screen. Through setting up like this, the user pops up private information if the screen of finding terminal equipment pops up at the in-process of throwing the screen, can shelter from this private information in this terminal equipment's the display screen with the hand, this moment this terminal equipment can send corresponding display screen to shelter from regional information to throwing the screen equipment to control this and throw the screen equipment and shelter from the display content of self display screen corresponding region, thereby prevent this private information and show in throwing the screen of screen equipment, effectively reduce the risk that user private information reveals. In addition, in the process, the screen content of the non-private information area of the terminal equipment can still be normally projected and displayed, so that the influence on the projection display work is small.
Fig. 4 is a flowchart illustrating another screen projection control method applied to a terminal device according to an embodiment of the present application, and includes:
401. in the screen projection process, if preset gesture operation is detected, determining information of a coverage area of a gesture corresponding to the gesture operation on a display screen, determining the information of the coverage area as information of a shielding area of the display screen, and acquiring a gesture image corresponding to the coverage area;
the screen projection is a process of sending the current display content of the display screen of the terminal device to the screen projection device and displaying the current display content on the screen of the screen projection device. In the screen projection process, if the terminal device detects a preset gesture operation, determining information of a coverage area of a gesture corresponding to the gesture operation on a display screen. For example, if a gesture operation of spreading a palm, which is performed by a user on a touch screen or a floating screen of the terminal device, is detected, an area covered by the palm on the display screen is detected, and information such as position coordinates of the area is acquired. Then, the information of the coverage area is determined as the information of the shielding area of the display screen, and meanwhile, a corresponding gesture image can be shot through a camera and other devices.
402. And sending the information of the shielding area of the display screen and the gesture image to a screen projection device so as to instruct the screen projection device to display the gesture image in the corresponding area of the display screen of the screen projection device according to the information of the shielding area of the display screen so as to shield the display content of the corresponding area.
And then, the terminal equipment sends the information of the display screen shielding area and the gesture image to the screen projection equipment. The screen projection equipment can display the gesture image in the corresponding area of the display screen of the screen according to the information of the shielding area of the display screen, so that the display content of the corresponding area is shielded, and the shielding of the privacy information is realized.
In addition, the terminal device may further obtain a pre-stored image, and send the pre-stored image (for example, a mosaic image) to the screen projection device, so that the screen projection device blocks the privacy information by using the pre-stored image. Or, the terminal device may further obtain a pre-stored multimedia file, and send the multimedia file to the screen projection device, so that the screen projection device displays and plays the multimedia file in the corresponding area. The user can pre-specify a multimedia file related to the current screen projection display work, and the multimedia file is displayed and played in a corresponding area popped up by the privacy information. Through setting up like this, on the basis of effectively protecting user privacy information, can further promote the effect of throwing screen display work, the practicality is better.

According to the embodiment of the application, the gesture shielding mode is adopted, the display content of the corresponding area in the screen projection equipment can be rapidly shielded, and therefore the privacy information safety of a user is effectively protected. In addition, the screen projection display work is not interrupted in the process, so that the influence on the screen projection display work is small.
Fig. 5 is a flowchart illustrating another screen projection control method applied to a terminal device according to an embodiment of the present application, and includes:
501. in the screen projection process, if the shielding operation of the display screen is detected, the shielding area information of the display screen is determined;
502. sending the information of the shielding area of the display screen to a screen projection device to indicate the screen projection device to shield the display content of the area corresponding to the display screen of the screen projection device according to the information of the shielding area of the display screen;
the steps 501-502 are the same as the steps 301-302, and the related description of the steps 301-302 can be referred to.
503. In the screen projection process, if the placement state of the display screen is detected to be converted from the upward state to the downward state, the screen projection is suspended;
504. in the process of suspending screen projection, if the placement state of the display screen is detected to be converted from the downward state to the upward state, screen projection is resumed.
In the screen projection process, if the terminal equipment detects that the placement state of the display screen is switched from an upward state to a downward state, the screen projection is suspended; in the process of suspending screen projection, if the terminal equipment detects that the placement state of the display screen is changed from a downward state to an upward state, screen projection is resumed. This is a convenient operation mode of upset terminal equipment, for example, the user throws the screen to the in-process of large-screen TV with the cell-phone, if find the cell-phone pops out privacy information, then the user can overturn the cell-phone screen downwards to in time interrupt throws the screen, prevents that this privacy information from revealing. After the user closes the private information popped up by the mobile phone, the screen of the mobile phone can be turned upwards, so that screen projection is recovered, and screen projection display work is continued.
In addition, it should be noted that, although the embodiment of the present application only lists the case where the placement state of the display screen is changed from the upward state to the downward state, and from the downward state to the upward state, any case of changing the orientation of the placement state, such as the front-back orientation, the tilt angle orientation, etc., that can be thought by those skilled in the art, should fall within the protection scope of the present application.
According to the embodiment of the application, except that the privacy information is shielded by adopting the display screen shielding operation, another operation mode capable of quickly interrupting the screen projection is adopted, so that the privacy information safety of a user is better protected. The operation mode is specifically that in the screen projection process, if the terminal equipment detects that the placement state of the display screen is switched from an upward state to a downward state, the screen projection is suspended; in the process of suspending screen projection, if the terminal equipment detects that the placement state of the display screen is changed from a downward state to an upward state, screen projection is resumed. By adopting the convenient operation mode of turning the terminal equipment, the user can interrupt the screen projection in time, and the privacy information is prevented from being revealed.
Fig. 6 shows a flowchart of another screen projection control method applied to a terminal device according to an embodiment of the present application, including:
601. in the screen projection process, if the shielding operation of the display screen is detected, the shielding area information of the display screen is determined;
602. sending the information of the shielding area of the display screen to a screen projection device to indicate the screen projection device to shield the display content of the area corresponding to the display screen of the screen projection device according to the information of the shielding area of the display screen;
the steps 601-602 are the same as the steps 301-302, and the related description of the steps 301-302 can be referred to.
603. In the screen projection process, if the current display content of the display screen contains preset content, controlling the screen projection equipment not to display the preset content.
In the screen projection process, if the terminal device detects that the current display content of the display screen contains preset content, the screen projection device is controlled not to display the preset content. The preset content can be private content which the user does not want to screen, such as short messages, WeChat information and video request information. The user can perform screen projection privacy setting on the terminal device in advance to set which application software or information popped up by the functional module belongs to the preset content needing to be shielded.
Specifically, the implementation of step 603 may include the following two ways:
(1) in the screen projection process, if the terminal device detects that the current display content of the display screen contains preset content, the display content with the preset content removed is sent to the screen projection device, so that the content displayed by the screen projection device does not contain the preset content.
(2) In the screen projection process, if the terminal device detects that the current display content of the display screen contains preset content, the screen projection device is instructed to shield the preset content when the display content is displayed.
As for the method (1), if the terminal device detects that the current display content includes the preset content, the content is removed, so that the content finally sent to the screen projection device for display does not include the content. For example, if the user presets that the information popped up by the WeChat belongs to the preset content, the terminal device sends the display content without the WeChat information to the screen projection device for displaying after detecting that the current display content contains the popped up WeChat information, so that the WeChat information is prevented from being displayed on the screen of the screen projection device.
As for the method (2), if the terminal device detects that the current display content includes the preset content, the terminal device may instruct the screen projection device to shield the preset content when displaying the display content. In this way, the terminal device may send all display contents including the preset content to the screen projection device, and may also send a control instruction to the screen projection device to instruct the screen projection device to mask the preset content when displaying the display content. The specific information shielding manner is not limited, and for example, the received preset content may not be displayed, or an information shielding window may be constructed to shield the preset content, and the like.
According to the method and the device for screening the privacy information, the privacy information is screened by adopting a display screen screening operation, another mode capable of screening the privacy information is adopted, specifically, in the screen screening process, if the terminal device detects that the current display content of the display screen contains the preset content, the screen screening device is controlled not to display the preset content. The user can carry out screen projection privacy setting on the terminal equipment in advance to set which application software or information popped up by the functional module belongs to the content to be shielded, and in the screen projection process, the part of content cannot be displayed on the screen of the screen projection equipment, so that the privacy information safety of the user is effectively protected.
Fig. 7 is a flowchart illustrating a screen projection control method applied to a screen projection device according to an embodiment of the present application, and includes:
701. in the screen projection process, if receiving display screen shielding area information sent by terminal equipment, determining a corresponding area of a display screen of the screen projection equipment, wherein the corresponding area is an area corresponding to the display screen shielding area information;
the screen projection is a process of sending the current display content of the display screen of the terminal device to the screen projection device and displaying the current display content on the screen of the screen projection device. In the screen projection process, if the screen projection equipment receives the information of the shielding area of the display screen sent by the terminal equipment, determining the corresponding area of the display screen of the screen projection equipment, wherein the corresponding area is the area corresponding to the information of the shielding area of the display screen. And the display screen shielding area information is generated by the terminal equipment after the display screen shielding operation is detected. For example, if a user blocks a part of or all of the display screen of the terminal device with a hand or other objects, the terminal device is triggered to generate corresponding display screen blocking area information.
702. And shielding the display content of the corresponding area.
After determining the corresponding area of the display screen of the screen projection equipment, the screen projection equipment shields the display content of the corresponding area. After receiving the information of the display screen shielding area sent by the terminal device, the screen projection device can determine the area which needs to be shielded on the display screen of the screen projection device according to the information of the position coordinates and the like contained in the information, and then shield the display content of the area by adopting a preset mode.
Further, the blocking the display content of the corresponding region may include:
and acquiring a pre-stored static image or dynamic image, cutting the static image or dynamic image to the size of the corresponding area, and displaying the cut static image or dynamic image in the corresponding area to shield the display content of the corresponding area.
The screen projection equipment can acquire a static image or a dynamic image which is pre-stored by the screen projection equipment, and displays the cut image in the corresponding area after cutting the image to the size of the corresponding area, so that the display content of the corresponding area is shielded. In addition, the still image or the moving image may be an image transmitted from the terminal device.
Further, if receiving display screen occlusion area information sent by the terminal device, determining an area corresponding to the display screen occlusion area information on the display screen of the screen projection device may include:
if receiving display screen shielding area information and a gesture image sent by the terminal device, determining an area corresponding to the display screen shielding area information on the display screen of the screen projection device, wherein the gesture image is an image of a gesture for shielding the display screen of the terminal device.
Correspondingly, the blocking the display content of the corresponding region may include:
displaying the gesture image in the corresponding area to shield the display content of the corresponding area.
The screen projection equipment can display the gesture image in the corresponding area of the display screen of the screen according to the information of the shielding area of the display screen, so that the display content of the corresponding area is shielded, and the shielding of the privacy information is realized.
According to the embodiment of the application, in the screen projection process, if screen projection equipment receives display screen shielding area information sent by terminal equipment, the corresponding area of the display screen of the screen projection equipment is determined, and the display content of the corresponding area is shielded. The corresponding area is an area corresponding to the information of the display screen shielding area, and the information of the display screen shielding area is generated by the terminal equipment after the terminal equipment detects the display screen shielding operation. Through setting up like this, the user pops up private information if the screen of finding terminal equipment pops up at the in-process of throwing the screen, can shelter from this private information in this terminal equipment's the display screen with the hand, this moment this terminal equipment can send corresponding display screen to shelter from regional information to throwing the screen equipment to control this and throw the screen equipment and shelter from the display content of self display screen corresponding region, thereby prevent this private information and show in throwing the screen of screen equipment, effectively reduce the risk that user private information reveals. In addition, in the process, the screen content of the non-private information area of the terminal equipment can still be normally projected and displayed, so that the influence on the projection display work is small.
Fig. 8 shows an interaction flowchart of a screen projection control method provided in an embodiment of the present application, including:
801. in the screen projection process, if the terminal equipment detects the shielding operation of the display screen, determining the shielding area information of the display screen;
the screen projection is a process of sending the current display content of the display screen of the terminal device to the screen projection device and displaying the current display content on the screen of the screen projection device. In the screen projection process, if the terminal device detects a display screen shielding operation (for example, a part of or all of the area of the display screen of the terminal device is shielded by a hand or other objects), the shielding area information of the display screen is determined and generated, and the shielding area information of the display screen is used for determining the position of the shielded area on the display screen, and may be information such as position coordinates.

In addition, in the process, the screen content of the non-private information area of the terminal equipment can still be normally projected and displayed, so that the influence on the projection display work is small.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
For ease of understanding, the screen projection control method proposed in the present application is described below in several practical application scenarios.
Fig. 9 is a system schematic diagram of an application of the screen projection control method provided by the present application in an actual scene.
In fig. 9, the device for projecting a screen is a mobile phone, and the device for projecting a screen is a large screen television.
The mobile phone and the large-screen television can be connected in a Bluetooth mode, a data line mode or a wifi mode. Preferably, the operations such as device discovery and device connection can be performed through Bluetooth, and window data of the projection screen is transmitted through wifi, so that the data transmission delay is low.
In the process of the screen projection of the mobile phone to the large-screen television, if a user finds that the mobile phone pops up the private information, the user can shield the area where the mobile phone pops up the private information by hand, and at the moment, the mobile phone can detect the area information such as the position coordinates of the area shielded by the palm of the user and send the area information to the large-screen television. After receiving the area information, the large-screen television determines an area corresponding to the area information in the screen of the large-screen television, and generates a new window in the determined area so as to shield the popped privacy information. As shown in fig. 10, a gesture-blocked image or other preset images may be displayed in the window, and the popped-up private information may be blocked by the window, so that the security of the private information of the user is effectively protected. In addition, in the process, the screen content of the non-private information display area of the mobile phone can still be normally projected and displayed, so that the influence on the projection display work is small.
Except for shielding the privacy information by adopting a display screen shielding operation, the method of turning over the mobile phone to quickly interrupt screen projection can be adopted to protect the privacy information of the user. As shown in fig. 11, if the user finds that the mobile phone pops up the private information, the mobile phone screen may be turned to a downward state, at this time, the mobile phone may send an instruction to stop screen projection, suspend the screen projection operation, and the large-screen television displays its desktop content. After the user closes the privacy information of the mobile phone, if the user wants to resume screen projection, the mobile phone screen can be turned to the upward state, at this time, the mobile phone sends a screen projection resuming instruction, screen projection operation is resumed, and the content of the mobile phone screen is displayed again by the large-screen television, as shown in fig. 12. The operation time required by the user to turn over the mobile phone is far shorter than the operation time required by manually turning off the private information, so that the mode of quickly interrupting screen projection by turning over the mobile phone is adopted, and the safety of the private information of the user can be effectively protected.
On the other hand, the user can also perform screen projection privacy setting on the mobile phone in advance to set which application software or information popped up by the functional module belongs to the content to be shielded, and in the screen projection process, the part of the content cannot be displayed on the screen of the large-screen television, so that the privacy information safety of the user is effectively protected. As shown in fig. 13, the user may configure a screen-casting privacy mode on the mobile phone, and select application software or function modules that need to be shielded, such as pop-up window shielding, incoming call shielding, social software shielding, and the like. After the shielding is opened, the privacy information such as the mobile phone short message, various social software information, the video request and the popup cannot be projected to the large-screen television for displaying, so that the privacy information safety of the user is effectively protected. In addition, in the screen-casting privacy configuration shown in fig. 13, the functions of turning on and turning off in two ways of protecting the privacy information of the user, namely "gesture shielding" and "turning over mobile phone pause/restart" can be realized, and the user can freely select a screen-casting privacy protection strategy.
According to the method and the device, the privacy information safety of the user can be effectively protected in the screen projection process, and the influence on screen projection display work is small.
