[0063] The embodiment of the present invention provides a method for controlling screen brightness. Figure 3 , Figure 3 It is a flow chart of a first embodiment of a method for controlling screen projection brightness according to the present invention.

[0064] In this embodiment, the projection screen brightness control method includes the following steps:

[0065] Step S10: When it is detected that a first electronic device is connected, user operations in the first electronic device are monitored in real time.

[0066] It should be noted that the executor of this embodiment can be a screen projection transmitter and / or a screen projection receiver in the screen projection device, or it can be a first electronic device or a second electronic device. Among them, the first electronic device can be a terminal device used by the user, such as: mobile phones, personal computers, tablet computers and other electronic devices. The second electronic device can be a TV, or it can be a display device with 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.

[0067] In actual use, the screen projection transmitter is used to connect to the first electronic device. When the first electronic device is connected to the screen projection transmitter by wire or wirelessly, it can be determined that the first electronic device is connected. Preferably, in order to avoid screen projection interruption caused by fluctuations in the wireless network, the first electronic device can use wired access to the screen projection transmitter.

[0068] In a specific implementation, in order to avoid the interruption of screen projection due to insufficient power of the first electronic device, a charging module may be provided in the screen projection transmitter, and when the first electronic device is connected to the screen projection transmitter via a wired manner, the screen projection transmitter may also charge the first electronic device through the charging module. The charging module may be a lithium battery pack.

[0069] It can be understood that when the first electronic device is connected to the screen projection transmitter, the screen projection transmitter can read the data and instructions in the first electronic device, and determine whether the first electronic device interacts with the user based on the data and instructions running in the first electronic device, thereby monitoring the user operations in the first electronic device.

[0070] Of course, in actual use, the user can also install the screen projection software corresponding to the screen projector in the first electronic device, and use the screen projection software to replace the screen projection transmitter in the screen projector, thereby directly connecting the first electronic device to the screen projection receiver in the screen projector and transmitting data. At this time, when the first electronic device can be paired and connected with the screen projection receiver in the screen projector through the screen projection software, the screen projector can determine that the first electronic device is detected to be connected.

[0071] Step S20: When it is detected that the user selects the application to be projected, the running data in the application to be projected is read to obtain the data to be projected.

[0072] It should be noted that the application to be projected can be the application selected for data projection. After the first electronic device is connected to the projection transmitter, the user can operate in the first electronic device and select the application to be projected. At this time, the corresponding program projection instruction will be generated in the first electronic device. If the projection device detects that there is a program projection instruction in the first electronic device, it will determine that the user has selected the application to be projected. At this time, the running data in the application to be projected can be read, and the read running data can be used as the data to be projected. Among them, the running data may include: running interface data, running file data and other data.

[0073] Step S30: Obtain the application type corresponding to the application to be projected, and determine the screen brightness parameter of the second electronic device according to the application type.

[0074] It should be noted that the application type may include: video type, audio type, text type, drawing type, etc. The application type can be determined according to the main business type of the application to be projected. For example, assuming that the main file type of application A is a video file, the application type of application A can be determined to be a video type.

[0075] In a specific implementation, the application type corresponding to the application to be projected can be obtained by the projection transmitter in the projection device reading the program information of the application to be projected, and then determining the application type corresponding to the application to be projected based on the program information. Of course, the projection transmitter can also read the program information of the application to be projected, and then send the program information to the projection receiver, and the projection receiver determines the application type corresponding to the application to be projected based on the program information.

[0076] In actual use, determining the screen brightness parameter of the second electronic device according to the application type may be to search for brightness parameters pre-set for each application type, and use the searched brightness parameters as the screen brightness parameters of the second electronic device. For example, assuming that the brightness parameters include 0-100%, the brightness parameter is pre-set to 0% for the audio type; and the brightness parameter is pre-set to 70% for the text type.

[0077] Furthermore, in order to make the setting of the brightness parameter more flexible and meet the actual use requirements 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:

[0078] Matching the application type with a preset brightness adjustment strategy to determine a target brightness mode;

[0079] The brightness parameter corresponding to the target brightness mode is used as the screen brightness parameter of the second electronic device.

[0080] It should be noted that the preset brightness adjustment strategy may include a mapping relationship between application type and brightness mode. The preset brightness adjustment strategy can be pre-set by the administrator of the projector according to actual needs, for example: corresponding the audio type to the screen off mode, the video type to the always-on mode, the text type to the eye protection mode, and the drawing type to the drawing mode.

[0081] In actual use, different brightness modes may correspond to different brightness parameters. Users can 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 always-on mode is 100%.

[0082] It should be noted that matching the application type with the preset brightness adjustment strategy to obtain the target brightness mode may be to obtain the brightness mode corresponding to the application type recorded in the preset brightness adjustment strategy, and use the obtained brightness mode as the target brightness mode.

[0083] Step S40: Send the screen data to be projected and the screen brightness parameter to the second electronic device, so that the second electronic device adjusts the screen brightness according to the screen brightness parameter and projects and displays the screen data to be projected.

[0084] It should be understood that when the screen data to be projected and the screen brightness parameters are sent to the second electronic device, the second electronic device will display the screen data to be projected and adjust the brightness parameters of the screen in the device to the received screen brightness parameters, thereby adjusting the screen brightness. For example: assuming that the application type is an audio type, and the screen data to be projected is audio data, and the screen brightness parameter corresponding to the application type is 0%, when the second electronic device receives the screen data to be projected and the screen brightness parameters, it will adjust the screen brightness parameters to 0%, that is, turn off the screen, and then play the audio data in the off-screen state.

[0085] In a specific implementation, the second electronic device may not be a smart second electronic device, that is, the second electronic device cannot automatically adjust the screen brightness parameter according to the received brightness. In order to enable the brightness of the second electronic device to be adjusted normally in this case, step S40 in this embodiment may include:

[0086] Determining a screen brightness parameter of the second electronic device according to the brightness adjustment strategy, and generating a brightness adjustment instruction according to the screen brightness parameter;

[0087] The brightness adjustment instruction and the screen data to be projected are sent to a second electronic device, so that the second electronic device adjusts the screen brightness parameters according to the brightness adjustment instruction and projects and displays the screen data to be projected.

[0088] It should be noted that in order to adapt to different second electronic devices, generating brightness adjustment instructions based on screen brightness parameters can be accomplished by obtaining the device model of the second electronic device, determining the instruction type executable by the second electronic device based on the device model, and then generating brightness adjustment instructions based on the screen brightness parameters and the instruction type.

[0089] It is understandable that after receiving the brightness adjustment instruction, the second electronic device can directly execute the brightness adjustment instruction to adjust the screen brightness in the second electronic device, and then project the screen data for display.

[0090] In a specific implementation, after adjusting the screen brightness of the second electronic device according to the brightness adjustment strategy, the user may adjust the screen brightness according to his actual needs. In order to meet the actual use needs of the user, after step S40 in this embodiment, the following may also be included:

[0091] When receiving a brightness adjustment instruction, obtaining a service type corresponding to the brightness adjustment instruction;

[0092] If the service type is not an application switching type, and the screen brightness mode of the second electronic device is a screen-off mode, obtaining a screen brightness parameter of the second electronic device before the screen is turned off;

[0093] Generate a brightness restoration instruction according to the screen brightness parameter before the screen is turned off;

[0094] The brightness restoration instruction is sent to the second electronic device, so that the second electronic device restores the screen brightness according to the brightness restoration instruction.

[0095] It should be noted that the brightness adjustment instruction can be a command sent by the user to the screen projector through the remote control, or it can be a command generated by the screen projector based on voice sensing or radar sensing, or it can be a command generated when the user operates the first electronic device to switch the application that needs to be projected. According to the purpose of the brightness adjustment instruction, it can be divided into two categories: application switching type and non-application switching type. For example: if the user sends a brightness adjustment instruction to the screen projector through the remote control, the service type corresponding to the brightness adjustment instruction is the non-application switching type; if the user switches the application that needs to be projected by operating the first electronic device, thereby generating a brightness adjustment instruction, the service type corresponding to the brightness adjustment instruction is the application switching type.

[0096] In actual use, if the screen projector receives a brightness adjustment instruction, and the service type corresponding to the brightness adjustment instruction is not a service switching type, it means that the user only needs to adjust the brightness of the second electronic device, rather than changing the application that needs to be projected. At this time, it can be detected whether the screen brightness mode of the second electronic device is the screen off mode. If so, it means that the user wants to restore the screen brightness of the second electronic device to the state before the screen was turned off. Therefore, the pre-recorded screen brightness parameters of the second electronic device before the screen was turned off can be obtained, and then the screen brightness parameters before the screen was turned off can be sent to the second electronic device, so that the second electronic device can restore the screen brightness to the state before the screen was turned off according to the screen brightness parameters before the screen was turned off.

[0097] It can be understood that if a brightness adjustment instruction is received on the screen projector, and the service type corresponding to the brightness adjustment instruction is not a service switching type, but the screen brightness mode of the second electronic device is not the screen-off mode at this time, it means that the user only needs to fine-tune the screen brightness of the second electronic device. At this time, the target brightness parameter can be extracted from the brightness adjustment instruction, 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.

[0098] In a specific implementation, if the service type of the brightness adjustment instruction is an application switching type, it means that the user needs to switch the screen projection application. In order to still be able to perform screen projection display normally in this case, after the step of obtaining the service type corresponding to the brightness adjustment instruction when receiving the brightness adjustment instruction, the embodiment may also include:

[0099] If the service type is an application switching type, obtaining a target application after switching;

[0100] Read the running data in the target application, obtain the switching projection data, and obtain the application type corresponding to the target application to obtain the target application type;

[0101] Determining a brightness adjustment instruction according to the target application type;

[0102] The brightness adjustment instruction and the switching screen projection data are sent to the second electronic device, so that the second electronic device adjusts the screen brightness according to the brightness adjustment instruction and performs screen projection display of the switching screen projection data.

[0103] It should be noted that the target application can be an application that the user operates in the first electronic device and needs to cast the screen after the selected switch. At this time, the 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. Therefore, the running data in the target application can be read to obtain the switching projection data, and the screen brightness parameters can be determined according to the application type corresponding to the target application. Then, the brightness adjustment instruction is constructed according to the screen brightness parameters, and then the brightness adjustment instruction and the switching projection data are sent to the second electronic device, so that the second electronic device adjusts the screen brightness according to the brightness adjustment instruction, and switches the projection data to the switching projection data.

[0104] This embodiment monitors the user operation in the first electronic device in real time when the first electronic device is detected to be connected; when the user is detected to select the application to be projected, reads the running data in the application to be projected to obtain the data to be projected; obtains the application type corresponding to the application to be projected, and determines the screen brightness parameters of the second electronic device according to the application type; sends the data to be projected and the screen brightness parameters to the second electronic device, so that the second electronic device adjusts the screen brightness according to the screen brightness parameters, and projects the data to be projected. Since the image is not directly synchronized during screen projection, but the running data in the application to be projected is read, and the screen brightness parameters are controlled separately from the data to be projected, even if the screen of the first electronic device is turned off, it will not affect the projection display in the second electronic device.

[0105] refer to Figure 4 , Figure 4 It is a flow chart of a second embodiment of a screen projection brightness control method of the present invention.

[0106] Based on the above first embodiment, step S30 of the screen projection brightness control method of this embodiment further includes:

[0107] Step S301: Detect whether the application to be projected has a corresponding preset type tag.

[0108] It should be noted that when the projection transmitter of the screen projector is connected to the first electronic device, it can read the various applications in the first electronic device, determine the application type of each application according to the main business type of each application, and set a corresponding preset type label for each application. Therefore, when it is necessary to determine the application type of a certain application to be projected, it is possible to first detect whether there is a corresponding preset type label for the application to be projected.

[0109] Step S302: If there is a corresponding preset type tag, obtain the preset type tag corresponding to the application to be projected.

[0110] It can be understood that if there is a corresponding preset type tag for the application to be projected, the application type of the application to be projected can be determined through the preset type tag of the application, and therefore, the preset type tag of the application to be projected can be obtained.

[0111] Step S303: Searching for the application type corresponding to the application to be projected in the preset tag type mapping table according to the preset type tag.

[0112] It should be noted that when setting type labels for each application in the first electronic device, in order to minimize the modification of the application, the preset type labels are generally set in a small number of abbreviations. Therefore, when the preset type labels are obtained, it is necessary to search in the preset label type mapping table according to the preset type labels to determine the application type corresponding to the application to be projected. Among them, the preset label type mapping table may include a mapping relationship between each preset type label and the application type, and the mapping relationship can be pre-set by the administrator of the projector.

[0113] For example, the mapping relationships in the preset tag type mapping table include: the preset type tag "@MIC" corresponds to the application type "audio type", the preset type tag "@MOV" corresponds to the application type "video type", the preset type tag "@TXT" corresponds to the application type "text type", and the preset type tag "@PIC" corresponds to the application type "drawing type".

[0114] Furthermore, some users may prohibit the screen projector from reading the application in the first electronic device for privacy reasons. In this case, the screen projector cannot read the label set for the application in the first electronic device. In order to still be able to normally determine the application type of the application to be projected in this case, after step S301 in this embodiment, the following may also be included:

[0115] If there is no corresponding preset type tag, reading the program information of the application to be projected;

[0116] Detecting whether the program information has a corresponding type mapping record in a preset type mapping table;

[0117] If there is a corresponding type mapping record, obtaining the type mapping record corresponding to the program information in the preset type mapping table to obtain a target mapping record;

[0118] The target mapping record is parsed to obtain the application type corresponding to the application to be projected.

[0119] It should be noted that if there is no corresponding preset type label for the application to be projected, it means that the projector cannot set a label for the application to be projected in advance. At this time, in order to determine the application type of the application to be projected, the program information of the application to be projected can be read, where the program information may include: application development manufacturer, application version number, application name and other information.

[0120] It should be noted that the preset type mapping table includes a mapping relationship between program information of different application programs and application types, and the mapping relationship can be preset by the administrator of the screen projector.

[0121] It can be understood that if there is a type mapping record corresponding to the program information, it means that the application type has been set in advance for the program information of the application. Therefore, the type mapping record corresponding to the program information of the application to be projected in the preset type mapping table can be searched, and the found type mapping record can be used as the target mapping record. The target mapping record is then parsed to extract the application type in the target mapping record, thereby obtaining the application type corresponding to the application to be projected.

[0122] Furthermore, since the administrator can generally only set some commonly used applications when presetting the preset type mapping table, but cannot set all applications, it is inevitable that some applications have no corresponding type mapping records. In this case, the user can set the application type for the application. Therefore, after the step of detecting whether the program information has a corresponding type mapping record in the preset type mapping table, the present embodiment may further include:

[0123] If there is no corresponding type mapping record, sending a type setting interface to the first electronic device, so that the first electronic device displays the type setting interface;

[0124] Receiving a type setting instruction input by a user based on the type setting interface;

[0125] Determine the application type corresponding to the application to be projected according to the type setting instruction.

[0126] It should be noted that the type setting interface can be generated based on the application to be projected, which may include the program information of the application to be projected and all settable application types. The user can select the application type in the type setting interface displayed on the first electronic device, and the first electronic device will generate a type setting instruction based on the user's selection, and send the type setting instruction to the projector. The projector parses the type setting instruction to determine the application type corresponding to the application to be projected. Among them, determining the application type corresponding to the application to be projected according to the type setting instruction can be to parse the type setting instruction, obtain the application type contained in the type setting instruction, and thus obtain the application type corresponding to the application to be projected.

[0127] Furthermore, in order to avoid the user having to set the application type for the same application multiple times, which may lead to a poor user experience, after the step of determining the application type corresponding to the application to be projected according to the type setting instruction described in this embodiment, the following may also be included:

[0128] Generate a type mapping record according to the type setting instruction and the program information;

[0129] The type mapping record is added to the preset type mapping table.

[0130] It should be noted that generating a type mapping record according to the type setting instruction and program information can be to determine the application type corresponding to the application to be projected according to the type setting instruction, or to parse the type setting instruction to obtain the application type contained in the type setting instruction, and then generate a type mapping record according to the application type and program information.

[0131] It can be understood that by adding the type mapping record to the preset type mapping table, the application type of the application to be projected can be determined based on the type mapping record thereafter without the user having to manually set it again, thereby avoiding the need for the user to set the application type for the same application multiple times, resulting in a poor user experience.

[0132] Step S304: Determine the screen brightness parameter of the second electronic device according to the application type.

[0133] In actual use, determining the screen brightness parameter of the second electronic device according to the application type may be to search for brightness parameters pre-set for each application type, and use the searched brightness parameters as the screen brightness parameters of the second electronic device. For example, assuming that the brightness parameters include 0-100%, the brightness parameter is pre-set to 0% for the audio type; and the brightness parameter is pre-set to 70% for the text type.

[0134] This embodiment detects whether there is a corresponding preset type tag for the application to be projected; if there is a corresponding preset type tag, obtains the preset type tag corresponding to the application to be projected; searches for the application type corresponding to the application to be projected in the preset tag type mapping table according to the preset type tag; and determines the screen brightness parameter of the second electronic device according to the application type. Since the application in the first electronic device can be read in advance when the first electronic device is connected, and a corresponding preset type tag is set for each application, when it is necessary to determine the application type of the application to be projected, it can be quickly determined according to the preset type tag corresponding to the application to be projected, thereby improving the execution efficiency of the projection brightness control method of the present invention.

[0135] In addition, an embodiment of the present invention further proposes a storage medium, on which a screen projection brightness control program is stored. 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.

[0136] Reference Figure 5 , Figure 5 FIG. 1 is a structural block diagram of the first embodiment of the screen projection brightness control device of the present invention. Figure 5 As shown, the projection screen brightness control device proposed in the embodiment of the present invention includes:

[0137] The operation monitoring module 10 is used to monitor the user operation in the first electronic device in real time when the first electronic device is detected to be connected;

[0138] The data acquisition module 20 is used to read the running data in the application to be projected and obtain the data to be projected when it is detected that the user selects the application to be projected;

[0139] A parameter determination module 30 is used to obtain an application type corresponding to the application to be projected, and determine a screen brightness parameter of the second electronic device according to the application type;

[0140] The data transmission module 40 is used to send the screen data to be projected and the screen brightness parameter to the second electronic device, so that the second electronic device adjusts the screen brightness according to the screen brightness parameter and projects the screen data to be projected.

[0141] This embodiment monitors the user operation in the first electronic device in real time when the first electronic device is detected to be connected; when the user is detected to select the application to be projected, reads the running data in the application to be projected to obtain the data to be projected; obtains the application type corresponding to the application to be projected, and determines the screen brightness parameters of the second electronic device according to the application type; sends the data to be projected and the screen brightness parameters to the second electronic device, so that the second electronic device adjusts the screen brightness according to the screen brightness parameters, and projects the data to be projected. Since the image is not directly synchronized during screen projection, but the running data in the application to be projected is read, and the screen brightness parameters are controlled separately from the data to be projected, even if the screen of the first electronic device is turned off, it will not affect the projection display in the second electronic device.

[0142] Furthermore, the parameter determination module 30 is also used to detect whether there is a corresponding preset type tag for the application to be projected; if there is a corresponding preset type tag, obtain the preset type tag corresponding to the application to be projected; and search the preset tag type mapping table for the application type corresponding to the application to be projected according to the preset type tag.

[0143] Furthermore, the parameter determination module 30 is also used to read the program information of the application to be projected if there is no corresponding preset type tag; detect whether there is a corresponding type mapping record for the program information in the preset type mapping table; if there is a corresponding type mapping record, obtain the type mapping record corresponding to the program information in the preset type mapping table to obtain the target mapping record; parse the target mapping record to obtain the application type corresponding to the application to be projected.

[0144] Furthermore, the parameter determination module 30 is further configured to match the application type with a preset brightness adjustment strategy to determine a target brightness mode; and use the brightness parameter corresponding to the target brightness mode as the screen brightness parameter of the second electronic device.

[0145] Furthermore, the data transmission module 40 is also used to determine the screen brightness parameters of the second electronic device according to the brightness adjustment strategy, and generate a brightness adjustment instruction according to the screen brightness parameters; send the brightness adjustment instruction and the screen data to be projected to the second electronic device, so that the second electronic device adjusts the screen brightness according to the brightness adjustment instruction, and projects the screen data to be projected.

[0146] Furthermore, the data transmission module 40 is also used to obtain the service type corresponding to the brightness adjustment instruction when receiving the brightness adjustment instruction; if the service type is not an application switching type, and the screen brightness mode of the second electronic device is a screen off mode, then obtain the screen brightness parameters of the second electronic device before the screen is turned off; generate a brightness recovery instruction according to the screen brightness parameters before the screen is turned off; and send the brightness recovery instruction to the second electronic device, so that the second electronic device restores the screen brightness according to the brightness recovery instruction.

[0147] Furthermore, the data transmission module 40 is also used to obtain the target application after switching if the business type is an application switching type; read the running data in the target application to obtain the switching projection data, and obtain the application type corresponding to the target application to obtain the target application type; determine the brightness adjustment instruction according to the target application type; send the brightness adjustment instruction and the switching projection data to the second electronic device, so that the second electronic device adjusts the screen brightness according to the brightness adjustment instruction, and projects the switching projection data.
