An embodiment of the present invention provides a screen projection brightness control method, and referring to fig. 3, fig. 3 is a flowchart illustrating a first embodiment of a screen projection brightness control method according to the present invention.
In this embodiment, the screen projection brightness control method includes the following steps:
step S10: when the access of the first electronic equipment is detected, the user operation in the first electronic equipment is monitored in real time.
It should be noted that the execution subject of the present embodiment may be a screen projection transmitter and/or a screen projection receiver in a screen projector, and may also be a first electronic device or a second electronic device. The first electronic device may be a terminal device used by a user, for example: mobile phones, personal computers, tablet computers and other electronic devices. The second electronic device may be a television, or may be a display device having a display function, such as a monitor or a projector. In this embodiment and the following embodiments, the screen projection brightness control method of the present invention is described by taking a screen projection transmitter, a screen projection receiver, a first electronic device, or a second electronic device as an example.
In practical use, the screen projection transmitter is used for being connected with the first electronic device, and when the first electronic device is connected with the screen projection transmitter in a wired mode or a wireless mode, it can be judged that the first electronic device is detected to be connected. Preferably, in order to avoid interruption of the screen projection due to fluctuation of the wireless network, the first electronic device may access the screen projection transmitter in a wired manner.
In concrete implementation, in order to avoid throwing the screen interruption in order to avoid the insufficient electric quantity of first electronic equipment, throw and can also be provided with the module of charging in the screen transmitter, throw the screen transmitter and can also charge for first electronic equipment through the module of charging when throwing the screen transmitter through wired mode access at first electronic equipment. Wherein, the charging module can be a lithium battery pack.
It can be understood that, when the first electronic device is connected to the screen projection transmitter, the screen projection transmitter may read data and instructions in the first electronic device, and may determine whether the first electronic device interacts with the user according to the data and instructions running in the first electronic device, so as to monitor the user operation in the first electronic device.
Certainly, in actual use, a user may also install screen projection software corresponding to the screen projector in the first electronic device, and replace the screen projection transmitter in the screen projector through the screen projection software, so that the first electronic device is directly connected with the screen projection receiver in the screen projector and data transmission is performed, and at this time, when the first electronic device is connected in a pairing manner with the screen projection receiver in the screen projector through the screen projection software, the screen projector may determine that the first electronic device is detected to be accessed.
Step S20: when it is monitored that a user selects an application program to be screen-projected, reading operation data in the application program to be screen-projected to obtain data to be screen-projected.
It should be noted that the application to be subjected to screen projection may be an application selected for data screen projection. After the first electronic device is connected with the screen projection transmitter, a user can operate in the first electronic device to select an application program needing screen projection, a corresponding program screen projection instruction can be generated in the first electronic device at the moment, if the screen projection device detects that the program screen projection instruction exists in the first electronic device, the user can be judged and monitored to select the application program to be screen projected, at the moment, the running data in the application program to be screen projected can be read, and the read running data is used as the data to be screen projected. Wherein the operational data may include: and operating interface data, operated file data and the like.
Step S30: and acquiring an application type corresponding to the application program to be projected, and determining a screen brightness parameter of the second electronic equipment according to the application type.
It should be noted that the application types may include: video type, audio type, text type, drawing type, etc. The application type may be determined according to the main service type of the application program to be screened, for example: assuming that the file type mainly operated by the application a is a video file, it can be determined that the application type of the application a is a video type.
In a specific implementation, the program information of the application program to be projected can be read by a screen projecting transmitter in the screen projector to acquire the application type corresponding to the application program to be projected, and then the application type corresponding to the application program to be projected is determined according to the program information. Certainly, the application type corresponding to the application program to be projected can also be determined by the screen projection receiver according to the program information.
In practical use, determining the screen brightness parameter of the second electronic device according to the application type may be to search a brightness parameter set for each application type in advance, and use the searched brightness parameter as the screen brightness parameter of the second electronic device. For example: assuming that the luminance parameter includes 0-100%, setting the luminance parameter to 0% for the audio type in advance; the brightness parameter is set in advance to 70% for the text type.
Further, in order to make the setting of the brightness parameter more flexible and meet the actual use requirement of the user, the step of determining the screen brightness parameter of the second electronic device according to the application type in this embodiment may include:
matching the application type with a preset brightness adjustment strategy to determine a target brightness mode;
and taking the brightness parameter corresponding to the target brightness mode as a screen brightness parameter of the second electronic device.
It should be noted that the preset brightness adjustment policy may include a mapping relationship between an application type and a brightness mode, and the preset brightness adjustment policy may be preset by a manager of the screen projector according to actual needs, for example: the audio type corresponds to a screen-off mode, the video type corresponds to a normally bright mode, the text type corresponds to an eye-protection mode, and the drawing type corresponds to a drawing mode.
In actual use, different brightness modes may correspond to different brightness parameters, and a user may adjust the brightness parameters corresponding to each brightness mode according to actual needs, for example: the brightness parameter corresponding to the screen-off mode is 0%, and the brightness parameter corresponding to the normally-on mode is 100%.
It should be noted that, the matching of the application type and the preset brightness adjustment policy to obtain the target brightness mode may be to obtain a brightness mode corresponding to the application type recorded in the preset brightness adjustment policy, and use the obtained brightness mode as the target brightness mode.
Step S40: and sending the screen data to be projected and the screen brightness parameter to the second electronic equipment so that the second electronic equipment adjusts the screen brightness according to the screen brightness parameter and performs screen projection display on the screen data to be projected.
It should be understood that the data to be projected and the screen brightness parameter are sent to the second electronic device, and then the second electronic device displays the data to be projected and adjusts the brightness parameter of the screen in the device to the received screen brightness parameter, thereby adjusting the screen brightness. For example: assuming that the application type is an audio type, the data to be projected is audio data, and the screen brightness parameter corresponding to the application type is 0%, the second electronic device adjusts the screen brightness parameter to 0% when receiving the data to be projected and the screen brightness parameter, that is, turns off the screen, and then plays the audio data in the screen off state.
In a specific implementation, the second electronic device may not be an intelligent second electronic device, that is, the second electronic device cannot automatically adjust the screen brightness parameter according to the received brightness, and in order to enable the brightness of the second electronic device to be normally adjusted under such a circumstance, the step S40 in this embodiment may include:
determining a screen brightness parameter of the second electronic equipment according to the brightness adjusting strategy, and generating a brightness adjusting instruction according to the screen brightness parameter;
and sending the brightness adjusting instruction and the screen data to be projected to second electronic equipment so that the second electronic equipment adjusts the screen brightness parameter according to the brightness adjusting instruction and performs screen projection display on the screen data to be projected.
It should be noted that, in order to adapt to different second electronic devices, the generating of the brightness adjustment instruction according to the screen brightness parameter may be to obtain a device model of the second electronic device, determine a type of an instruction executable by the second electronic device according to the device model, and then generate the brightness adjustment instruction according to the screen brightness parameter and the type of the instruction.
It can be understood that, after receiving the brightness adjustment instruction, the second electronic device may directly run the brightness adjustment instruction, so as to adjust the screen brightness in the second electronic device, and then perform screen projection display on the data to be projected.
In a specific implementation, after adjusting the screen brightness of the second electronic device according to the brightness adjustment policy, the user may adjust the screen brightness according to an actual need of the user, and in order to meet an actual use requirement of the user, after the step S40, the method may further include:
when a brightness adjusting instruction is received, acquiring a service type corresponding to the brightness adjusting instruction;
if the service type is not the application switching type and the screen brightness mode of the second electronic device is the screen-off mode, acquiring a screen brightness parameter of the second electronic device before the screen is turned off;
generating a brightness recovery instruction according to the screen brightness parameter before the screen is turned off;
and sending the brightness recovery instruction to the second electronic equipment so that the second electronic equipment recovers the screen brightness according to the brightness recovery instruction.
It should be noted that the brightness adjustment instruction may be an instruction sent to the screen projector by the user through the remote controller, may also be an instruction generated by being sensed by the screen projector based on voice sensing or radar sensing, or may also be an instruction generated when the user operates the first electronic device to switch the application program to be screened. According to the purpose of the brightness adjustment command, two main categories can be distinguished: application switching type and non-application switching type, for example: if the user sends a brightness adjusting instruction to the screen projector through the remote controller, the service type corresponding to the brightness adjusting instruction is a non-application switching type; if the user switches the application program needing screen projection by operating the first electronic device, so as to generate a brightness adjusting instruction, the service type corresponding to the brightness adjusting instruction is the application switching type.
In actual use, if the screen projector receives the brightness adjusting instruction and the service type corresponding to the brightness adjusting instruction is not the service switching type, it indicates that the user only needs to adjust the brightness of the second electronic device, but does not change the application program that needs to be projected, and at this time, it may be detected whether the screen brightness mode of the second electronic device is the screen-off mode, and if so, it indicates that the user wants to restore the screen brightness of the second electronic device to the state before screen-off, so that the pre-recorded screen brightness parameter before screen-off of the second electronic device may be obtained, and then the screen brightness parameter before screen-off is sent to the second electronic device, so that the second electronic device restores the screen brightness to the state before screen-off according to the screen brightness parameter before screen-off.
It can be understood that, if the screen projector receives the brightness adjustment instruction, and the service type corresponding to the brightness adjustment instruction is not the service switching type, but the screen brightness mode of the second electronic device is not the screen-off mode at this time, it indicates that the user only needs to perform fine adjustment on the screen brightness of the second electronic device, and then the target brightness parameter may be extracted from the brightness adjustment instruction at this time, and then the target brightness parameter is sent to the second electronic device, so that the second electronic device adjusts the brightness parameter of the screen in the device to the target brightness parameter.
In a specific implementation, if the service type of the brightness adjustment instruction is an application switching type, it indicates that the user needs to switch the application program for screen projection, and in order to still perform screen projection display normally under such a situation, after the step of obtaining the service type corresponding to the brightness adjustment instruction when the brightness adjustment instruction is received in this embodiment, the method may further include:
if the service type is an application switching type, acquiring a switched target application program;
reading the running data in the target application program, obtaining switching screen projection data, and obtaining an application type corresponding to the target application program to obtain a target application type;
determining a brightness adjusting instruction according to the target application type;
and sending the brightness adjusting instruction and the switching screen projection data to the second electronic equipment so that the second electronic equipment adjusts the screen brightness according to the brightness adjusting instruction and performs screen projection display on the switching screen projection data.
The target application may be an application that the user needs to perform screen projection after performing operation in the first electronic device and switching the selection. At this time, the screen projection data in the second electronic device needs to be changed, and the brightness also needs to be modified according to the application type of the target application program, so that the operating data in the target application program can be read, the screen switching projection data can be obtained, the screen brightness parameter can be determined according to the application type corresponding to the target application program, then the brightness adjusting instruction can be established according to the screen brightness parameter, and then the brightness adjusting instruction and the screen switching projection data can be sent to the second electronic device, so that the second electronic device can adjust the screen brightness according to the brightness adjusting instruction, and the screen projection data can be switched into the screen switching projection data.
In the embodiment, when the access of the first electronic device is detected, the user operation in the first electronic device is monitored in real time; when it is monitored that a user selects an application program to be screen-projected, reading operation data in the application program to be screen-projected to obtain data to be screen-projected; acquiring an application type corresponding to the application program to be projected, and determining a screen brightness parameter of the second electronic equipment according to the application type; and sending the screen data to be projected and the screen brightness parameter to the second electronic equipment so that the second electronic equipment adjusts the screen brightness according to the screen brightness parameter and performs screen projection display on the screen data to be projected. Because the image is not directly synchronized when the screen is projected, the running data in the application program to be projected is read, and the screen brightness parameter and the data to be projected are separately controlled, even if the first electronic device is turned off, the screen projection display in the second electronic device cannot be influenced.
Referring to fig. 4, fig. 4 is a flowchart illustrating a projection brightness control method according to a second embodiment of the present invention.
Based on the first embodiment, the step S30 of the screen projection brightness control method of this embodiment further includes:
step S301: and detecting whether the application program to be screened has a corresponding preset type label.
It should be noted that, when the first electronic device is accessed, the screen projector of the screen projector may read each application program in the first electronic device, determine the application type of each application program according to the main service type of each application program, and set a corresponding preset type tag for each application program, so that when the application type of a certain application program to be screen projected needs to be determined, it may be detected first whether the corresponding preset type tag exists in the application program to be screen projected.
Step S302: and if the corresponding preset type label exists, acquiring the preset type label corresponding to the application program to be screen-projected.
It can be understood that if the application program to be screen-projected has the corresponding preset type tag, the application type of the application program to be screen-projected can be determined through the preset type tag of the application program, and therefore, the preset type tag of the application program to be screen-projected can be obtained.
Step S303: and searching the application type corresponding to the application program to be screened in a preset label type mapping table according to the preset type label.
It should be noted that when the type tag is set for each application in the first electronic device, in order to reduce modifications to the application as much as possible, the preset type tag is generally set in a manner of a few abbreviations, and therefore when the preset type tag is obtained, the application type corresponding to the application to be screen-screened may be determined only by looking up in the preset tag type mapping table according to the preset type tag. The preset tag type mapping table may include a mapping relationship between each preset type tag and an application type, and the mapping relationship may be preset by a manager of the screen projector.
For example: the mapping relationship in the preset label type mapping table comprises the following steps: presetting type label "@ MIC" corresponds application type "audio type", presetting type label "@ MOV" corresponds application type "video type", presetting type label "@ TXT" corresponds application type "text type", presetting type label "@ PIC" corresponds application type "drawing type".
Further, some users may prohibit the screen projector from reading the application program in the first electronic device for privacy reasons, and at this time, the screen projector cannot read the setting tag for the application program in the first electronic device, and in order to still normally determine the application type of the application program to be projected under this situation, after step S301 in this embodiment, the method may further include:
if the corresponding preset type label does not exist, reading the program information of the application program to be screen-projected;
detecting whether the program information has a corresponding type mapping record in a preset type mapping table;
if the corresponding type mapping record exists, acquiring the corresponding type mapping record of the program information in the preset type mapping table, and acquiring a target mapping record;
and analyzing the target mapping record to obtain the application type corresponding to the application program to be projected.
It should be noted that, if there is no corresponding preset type tag for the application program to be screen-projected, it indicates that the screen projector cannot set a tag for the application program to be screen-projected in advance, and then, in order to determine the application type of the application program to be screen-projected, program information of the application program to be screen-projected may be read, where the program information may include: application developer, application version number, application name, etc.
It should be noted that the preset type mapping table includes mapping relationships between the program information of different application programs and the application types, and the mapping relationships may be preset by a manager of the screen projector.
It can be understood that, if a type mapping record corresponding to the program information exists, it indicates that the application type has been set for the program information of the application program in advance, and therefore, a type mapping record corresponding to the program information of the application program to be screen-projected in a preset type mapping table can be searched, the searched type mapping record is used as a target mapping record, then the target mapping record is analyzed, and the application type in the target mapping record is extracted, so as to obtain the application type corresponding to the application program to be screen-projected.
Further, since a manager can generally set only a part of commonly used application programs, but cannot set all application programs when setting the preset type mapping table in advance, it is inevitable that a part of application programs have no corresponding type mapping record, and at this time, a user may set an application type for the application program, and therefore, after the step of detecting whether the program information has a corresponding type mapping record in the preset type mapping table in this embodiment, the method may further include:
if the corresponding type mapping record does not exist, sending a type setting interface to the first electronic equipment so that the first electronic equipment displays the type setting interface;
receiving a type setting instruction input by a user based on the type setting interface;
and determining the application type corresponding to the application program to be projected according to the type setting instruction.
It should be noted that the type setting interface may be generated according to the application program to be screen-projected, where the type setting interface may include program information of the application program to be screen-projected and all settable application types. The user can select an application type in a type setting interface displayed on the first electronic device, the first electronic device can generate a type setting instruction according to the selection of the user, the type setting instruction is sent to the screen projector, and the screen projector analyzes the type setting instruction, so that the application type corresponding to the application program to be projected can be determined. The determining of the application type corresponding to the application program to be screen-projected according to the type setting instruction may be analyzing the type setting instruction to obtain the application type included in the type setting instruction, so as to obtain the application type corresponding to the application program to be screen-projected.
Further, in order to avoid poor user experience caused by requiring the user to set the application type for the same application program for multiple times, after the step of determining the application type corresponding to the application program to be screened according to the type setting instruction, the method may further include:
generating a type mapping record according to the type setting instruction and the program information;
and adding the type mapping record into the preset type mapping table.
It should be noted that, the generating of the type mapping record according to the type setting instruction and the program information may be determining, according to the type setting instruction, an application type corresponding to the application program to be screen-launched, or may be analyzing the type setting instruction to obtain an application type included in the type setting instruction, and then generating the type mapping record according to the application type and the program information.
It can be understood that the type mapping record is added to the preset type mapping table, and then the application type of the application program to be screen-projected can be determined according to the type mapping record without manual setting again by the user, so that poor user experience caused by the fact that the user needs to set the application type for the same application program for multiple times can be avoided.
Step S304: and determining the screen brightness parameter of the second electronic equipment according to the application type.
In practical use, determining the screen brightness parameter of the second electronic device according to the application type may be to search a brightness parameter set for each application type in advance, and use the searched brightness parameter as the screen brightness parameter of the second electronic device. For example: assuming that the luminance parameter includes 0-100%, setting the luminance parameter to 0% for the audio type in advance; the brightness parameter is set in advance to 70% for the text type.
The method comprises the steps of detecting whether a corresponding preset type label exists in the application program to be screened; if the corresponding preset type label exists, acquiring the preset type label corresponding to the application program to be screen-projected; searching an application type corresponding to the application program to be screened in a preset label type mapping table according to the preset type label; and determining the screen brightness parameter of the second electronic equipment according to the application type. The application program in the first electronic equipment can be read in advance when the first electronic equipment is accessed, and the corresponding preset type tags are set for the application programs, so that the application type of the application program to be projected can be determined quickly according to the preset type tags corresponding to the application program to be projected when the application type of the application program to be projected needs to be determined, and the execution efficiency of the screen projection brightness control method is improved.
In addition, an embodiment of the present invention further provides a storage medium, where a screen projection brightness control program is stored on the storage medium, and when the screen projection brightness control program is executed by a processor, the steps of the screen projection brightness control method described above are implemented.
