Description

Background Art

[0002] In order to meet the diverse needs of users, the functions of terminal devices are becoming increasingly rich. Many terminal devices can provide a screen mirroring function. Users can use a terminal device with a screen mirroring function to mirror some pictures to other terminal devices. For example, users can mirror the screen of a mobile phone to a TV so that the TV can display the screen of the mobile phone, etc.

[0003] In the existing screen mirroring technology, the commonly adopted method is that the screen mirroring terminal uses the default scheme to collect the display screen to be mirrored. After packing it into video stream data, it is directly sent to the receiving terminal. However, when mirroring the screen in this way, due to the differences in the image or video data processing capabilities of the receiving terminal and the screen mirroring terminal, there are certain differences in aspects such as color display between the picture presented by the receiving terminal and the picture presented by the screen mirroring terminal. As a result, when the picture is displayed on the receiving terminal, the display effect on the screen mirroring terminal cannot be well restored, affecting the user experience. Summary of the Invention

[0004] The present disclosure provides a screen mirroring method, a screen mirroring device, a computer-readable storage medium, and an electronic device, thereby at least to some extent improving the problem that there are differences in the screen display effects between the receiving terminal and the screen mirroring terminal in the prior art.

[0005] Other features and advantages of the present disclosure will become apparent through the following detailed description, or will be learned in part through the practice of the present disclosure.

[0009] According to a fourth aspect of the present disclosure, there is provided a screen mirroring device, including: a data acquisition module configured to acquire second data to be screen mirrored from a screen mirroring terminal, where the second data to be screen mirrored is obtained by the screen mirroring terminal performing display adjustment processing on first data to be screen mirrored by using display adjustment parameters for the terminal to be screen mirrored, and the display adjustment parameters are generated according to the performance information of the screen mirroring terminal and the performance information of the terminal to be screen mirrored; and a picture display module configured to display a corresponding picture according to the second data to be screen mirrored.

[0046] Figure 3 An exemplary process of the screen mirroring method is shown, which can be executed by the above-mentioned screen mirroring terminal 110, including the following steps S310 to S340:

[0047] Step S310, obtain the performance information of the terminal to be screen mirrored.

[0048] Among them, the performance information of the terminal to be screen mirrored may include various performance information in terms of hardware or software of the terminal to be screen mirrored. For example, the display performance information of the display screen of the terminal to be screen mirrored, and hardware performance information such as the performance information of the processor, or software performance information such as the parameter data set by the user in the terminal to be screen mirrored. Specifically, the performance information may include display performance information and processor performance information. Among them, the display performance information may include one or more of the color gamut information, brightness information, contrast information, or bit depth information of the display screen, and the processor performance information may include the effect mapping relationship between the processor source image data and the display screen, information on supported image display or video playback formats, and so on.

[0049] In this exemplary embodiment, when the screen-cast receiving terminal establishes a connection with the screen-cast terminal, the screen-cast receiving terminal can actively send performance information to the screen-cast terminal so that the screen-cast terminal can receive it in a timely manner. Additionally, in an exemplary embodiment, the above step S310 may include the following steps:

[0050] Send a performance information query request to the screen-cast receiving terminal;

[0051] In response to the screen-cast receiving terminal receiving the performance information query request, receive the performance information returned by the screen-cast receiving terminal.

[0052] That is, when the screen-cast receiving terminal establishes a connection with the screen-cast terminal, the screen-cast terminal has a need to obtain the performance information of the screen-cast receiving terminal, or actively requests performance information from the screen-cast receiving terminal, then the screen-cast receiving terminal will send the performance information to the screen-cast terminal to improve the effectiveness and efficiency of the performance information transmission. Specifically, after establishing a connection with the screen-cast receiving terminal, the screen-cast terminal can send a performance information query request to the screen-cast receiving terminal. This request can be a simple instruction request to obtain performance information, or a detailed request including which one or several types of performance information need to be obtained, etc. After receiving and responding to this performance information query request, the screen-cast receiving terminal can return the corresponding performance information to the screen-cast terminal.

[0053] It should be noted that there can be multiple screen-cast receiving terminals in this exemplary embodiment. When there are multiple screen-cast receiving terminals, the multiple screen-cast receiving terminals can send their respective performance information to the screen-cast terminal. The screen-cast terminal can also send a performance information query request to one or more of the screen-cast receiving terminals according to actual needs to obtain the performance information of some of the screen-cast receiving terminals, etc. The present disclosure does not make specific limitations on this.

[0054] Step S320, generate display adjustment parameters for the screen-cast receiving terminal according to the performance information of the screen-cast terminal and the performance information of the screen-cast receiving terminal.

[0055] Generally, due to the different performance information of terminal devices, when an image or video is displayed on different terminal devices, different display effects will be presented, such as color, color temperature, brightness, or contrast effects, etc. In this exemplary embodiment, in order to enable the screen-cast receiving terminal to have a consistent or similar display effect with the screen-cast terminal, display adjustment parameters adapted to the performance conditions of the screen-cast receiving terminal can be generated according to the performance information of the screen-cast terminal and the performance information of the screen-cast receiving terminal. Specifically, the display adjustment parameters can be generated based on the performance difference between the screen-cast terminal and the screen-cast receiving terminal. For example, according to the difference between the brightness information of the display screen of the screen-cast terminal and the brightness information of the display screen of the screen-cast receiving terminal, determine the mapping relationship of the brightness information so that the screen-cast receiving terminal can adjust its own brightness to be the same or similar to the brightness information of the screen-cast terminal according to this mapping relationship of the brightness information.

[0056] Step S330: Use the display adjustment parameters to perform display adjustment processing on the first data to be screen-cast, and obtain the second data to be screen-cast.

[0057] Among them, the first data to be screen-cast refers to the initial image data, video data, etc. in the screen-casting terminal before display adjustment processing, and the second data to be screen-cast refers to the data used to be sent to the receiving terminal after performing display adjustment processing on the first data to be screen-cast according to the display adjustment parameters.

[0058] In this exemplary embodiment, according to the determined display adjustment parameters, display adjustment processing can be performed on the first data to be screen-cast. Specifically, according to different display adjustment parameters, the display adjustment processing can include various types, such as performing gamut mapping processing, bit-depth transformation processing, brightness adjustment data, contrast adjustment processing, etc. on the first data to be screen-cast.

[0059] Step S340: Send the second data to be screen-cast to the receiving terminal, so that the receiving terminal displays the corresponding picture according to the second data to be screen-cast.

[0060] Finally, the second data to be screen-cast after display adjustment processing can be sent to the receiving terminal so that the receiving terminal displays the corresponding picture. It should be noted that the second data to be screen-cast represents the data for picture display in the receiving terminal. "Second" does not represent quantity. When there are multiple receiving terminals, the first data to be screen-cast can be processed according to the performance information of each receiving terminal to obtain multiple second data to be screen-cast, and different second data to be screen-cast can be displayed in the corresponding receiving terminals. When there are receiving terminals with the same performance information, the display adjustment processing process can also be performed only according to the performance information of one of the receiving terminals and then reused to other receiving terminals with the same performance information. In addition, the screen-casting terminal can also first scale the display picture corresponding to the generated second data to be screen-cast to a state that conforms to the aspect ratio of the display picture of the receiving terminal, for example, scale it according to the aspect ratio of the display picture of the receiving terminal, and send the processed second data to be screen-cast to the receiving terminal for picture display to ensure that the aspect ratio of the picture has a good display effect in the receiving terminal.

[0061] It should be noted that the second data to be screen-cast is data that has been processed from the first data to be screen-cast, is adapted to the performance of the terminal to be screen-cast, and is the same as or similar to the data display effect of the screen-casting terminal itself. When the performance information of the terminal to be screen-cast is higher than that of the screen-casting terminal, the generated display adjustment parameters can enable the adjusted second data to be screen-cast to have the same display effect as the first data to be screen-cast when displayed. For example, when the screen-cast image is displayed on the terminal to be screen-cast, it has the same brightness, contrast, etc. as the image displayed on the screen-casting terminal; when the performance information of the terminal to be screen-cast is lower than that of the screen-casting terminal, the generated display adjustment parameters can enable the adjusted second data to be screen-cast to have an approximate display effect as the first data to be screen-cast when displayed. For example, if the range of the brightness parameter of the terminal to be screen-cast is smaller than that of the screen-casting terminal, and the brightness parameter of the first data to be screen-cast is higher than the upper limit of the brightness parameter that the terminal to be screen-cast can achieve, then the display adjustment parameters can be generated based on the brightness information of the terminal to be screen-cast, and the first data to be screen-cast can be processed based on the display adjustment parameters, so that the generated second data to be screen-cast is as close as possible to the brightness of the first data to be screen-cast. Thus, on the one hand, the consistency of the screen display between the terminal to be screen-cast and the screen-casting terminal can be achieved, and on the other hand, when the performance of the terminal to be screen-cast is weaker than that of the screen-casting terminal, the image quality effect of the display screen of the terminal to be screen-cast can be improved to a certain extent.

[0062] In summary, in this exemplary embodiment, the performance information of the screen-cast target terminal is obtained; according to the performance information of the screen-casting terminal and the performance information of the screen-cast target terminal, display adjustment parameters for the screen-cast target terminal are generated; the first data to be screen-cast is subjected to display adjustment processing by using the display adjustment parameters to obtain second data to be screen-cast; and the second data to be screen-cast is sent to the screen-cast target terminal, so that the screen-cast target terminal displays a corresponding picture according to the second data to be screen-cast. On the one hand, a new screen-casting method is proposed in this exemplary embodiment. According to the performance information between the screen-casting terminal and the screen-cast target terminal, display adjustment parameters are determined to process the display adjustment of the data to be screen-cast through the display adjustment parameters. Since the display adjustment parameters are determined based on the performance between different terminals, the adjustment degree and direction of the display adjustment of the picture data can be accurately reflected, ensuring the accuracy and effectiveness of the adjustment of the display adjustment of the data to be screen-cast. On the other hand, this exemplary embodiment takes the obtained performance information of the screen-cast target terminal as a reference and the performance information of the screen-casting terminal as a reference to generate display adjustment parameters for the screen-cast target terminal, and adjusts the display adjustment of the first data to be screen-cast based on the parameters, fully considering the performance conditions of the screen-cast target terminal. The display adjustment process is adapted to the performance of the screen-cast target terminal, so that the generated second data to be screen-cast can be adaptively adjusted during display. In addition, while the second data to be screen-cast meets the performance requirements of the screen-cast target terminal, the data to be screen-cast can also be adjusted to have the same or similar display effect as the screen-casting terminal according to the display adjustment parameters, so as to realize that when the screen-cast data is displayed on the screen-cast target terminal in the screen-casting scenario, the display effect consistent with that on the screen-casting terminal can be retained as much as possible, improving the user's viewing experience.

[0063] In an exemplary embodiment, as Figure 4 shown, the above performance information may include display performance information, and the above step S320 may include the following steps:

[0064] Step S410, generating a display mapping parameter for the screen-cast target terminal according to the display performance information of the screen-casting terminal and the display performance information of the screen-cast target terminal, where the display adjustment parameter includes the display mapping parameter.

[0065] Further, the above step S330 may include:

[0066] Step S420, numerically mapping one or more display parameters in the first data to be screen-cast by using the display mapping parameter to obtain second data to be screen-cast.

[0067] Considering that the display performance standards or parameter ranges of different terminals are inconsistent, it may be difficult to apply to all application scenarios by simply performing data calculations based on incremental relationships. Therefore, in order to make the picture on the receiving terminal and the transmitting terminal have the same or similar display effects in terms of picture color gamut, contrast, or brightness, etc., this exemplary embodiment can generate display mapping parameters for the receiving terminal according to the differences between the display performance information of the transmitting terminal and the display performance information of the receiving terminal. The display mapping parameters may refer to the mapping relationship required for the terminals to achieve the same or similar display effects, and can be determined according to the mapping relationship of the parameter intervals of the display performance between different terminals. For example, the brightness parameter interval of the transmitting terminal is [a, b], and the brightness parameter interval of the receiving terminal is [c, d]. Through the brightness parameter intervals of the two, the mapping parameters for converting a fixed brightness between different intervals are determined. Through the display mapping parameters, the display parameter mapping can be performed on the first data to be transmitted of the transmitting terminal, so that when the generated second data to be transmitted is displayed on the receiving terminal, it has the same display effect as the transmitting terminal.

[0068] When using the display mapping parameters to perform display adjustment processing on the first data to be transmitted, this exemplary embodiment can select to perform numerical mapping on one or more display parameters in the first data to be transmitted. For example, the first data to be transmitted may include different display parameters such as brightness, contrast, and bit depth. Numerical mapping can be performed on the brightness, contrast, or both brightness and contrast among the above display parameters according to actual needs, or numerical mapping can be performed on all the display parameters included therein to meet the calculation requirements of different scenarios. For example, in scenarios where the requirements for certain display parameters are not high, numerical mapping of some display parameters can be selected to be ignored to improve the calculation efficiency and reduce the system calculation amount.

[0069] In an exemplary embodiment, as Figure 5 shown, the above screen mirroring method may further include the following steps:

[0070] Step S510, obtain the size of the display area and the size of the interaction area of the receiving terminal, and the interaction area is located within the display area;

[0071] The step of using the display adjustment parameters to perform display adjustment processing on the first data to be transmitted in step S330 may include:

[0072] Step S520, perform display adjustment processing on the first data to be transmitted according to the size relationship between the size of the display area and the size of the interaction area, and the display adjustment parameters.

[0073] Among them, the interaction area refers to the area on the display interface of the screen-cast receiving terminal that can be interactively operated and controlled by the user. For example, after the screen-cast transmitting terminal casts the screens of a game application and a chat application including split-screen display to the screen-cast receiving terminal, when the user operates in the game application, the area where the game application is located is the interaction area; or the screen-cast transmitting terminal scales the display area of a certain application and places it at a sub-area position in the display interface, and then casts the current display screen to the screen-cast receiving terminal, the position of the sub-area of the application in the display interface is the interaction area. As long as it is an area on the display interface that can be interactively operated and controlled by the user, it can be used as the interaction area. The interaction area can be the entire display area of the screen-cast receiving terminal. For example, when casting the display screen of an opened application to the screen-cast receiving terminal, if the user interacts with the current display area, the entire interface of the current display area is also the interaction area; the interaction area can also be a sub-area of the display area of the screen-cast receiving terminal. For example, when casting the display screens of multiple opened applications to the screen-cast receiving terminal, if the user interacts with one of the applications, the sub-area of the display area where the interacted application is located is the interaction area. As shown in Figure 6 As shown, the area 610 is the display area of the screen-cast receiving terminal, that is, the screen-cast area of the picture. Among them, either the area S or the area P can be used as the interaction area. In this exemplary embodiment, the screen-cast transmitting terminal can send a request instruction for the display area size and the interaction area size to the screen-cast receiving terminal through the network link. After the screen-cast receiving terminal receives and responds to the instruction, it returns the corresponding size information. Further, the screen-cast transmitting terminal can determine how to perform display adjustment processing on the first data to be screen-cast according to the display adjustment parameters based on the relationship between the received display area size and the interaction area size.

[0074] In an exemplary embodiment, the above step S520 may include the following steps:

[0075] If the size of the display area is greater than the size of the interaction area, perform display adjustment processing on the data corresponding to the interaction area in the first data to be screen-cast according to the display adjustment parameters;

[0076] If the size of the display area is equal to the size of the interaction area, perform display adjustment processing on the data corresponding to the display area or the interaction area in the first data to be screen-cast according to the display adjustment parameters.

[0077] In this exemplary embodiment, if the size of the display area is larger than that of the interaction area, it indicates that the user only interacts with a partial sub - area of the display area. At this time, in order to reduce the computational load of the display adjustment process and improve the efficiency of the display adjustment process, and also to highlight the area that has a closer interaction relationship with the current user, this exemplary embodiment can choose to use the display adjustment parameters to perform display adjustment processing only on the data corresponding to the interaction area in the first data to be screen - casted. If the size of the display area is equal to that of the interaction area, it means that the user can perform interaction operations on the entire area where the current display interface is located. At this time, display adjustment processing can be performed on the complete first data to be screen - casted. Specifically, it can be to perform display adjustment processing on the data corresponding to the display area in the first data to be screen - casted, or to perform display adjustment processing on the data corresponding to the interaction area in the first data to be screen - casted.

[0078] In one exemplary embodiment, before sending the second data to be screen - casted to the screen - casted terminal, the above - mentioned screen - casting method may further include the following steps:

[0079] When the screen - casted terminal supports the high - dynamic - range mode, process the second data to be screen - casted into the data format corresponding to the high - dynamic - range mode and send it to the screen - casted terminal;

[0080] When the screen - casted terminal does not support the high - dynamic - range mode, process the second data to be screen - casted into the data format corresponding to the standard - dynamic - range mode and send it to the screen - casted terminal.

[0081] In this exemplary embodiment, if the processor of the screen - casted terminal supports the high - dynamic - range mode, when the screen - casting terminal sends the second data to be screen - casted, it can first process it into the data format corresponding to the high - dynamic - range mode and then send it to the screen - casted terminal, so as to ensure that after the second data to be screen - casted is sent to the screen - casted terminal, a better picture effect can be displayed according to the performance mode of the screen - casting terminal. If the processor of the screen - casted terminal does not support the high - dynamic - range mode, when the screen - casting terminal sends the second data to be screen - casted, it can directly process it into the data format corresponding to the standard - dynamic - range mode and then send it to the screen - casted terminal.

[0082] Another screen - casting method is provided in the exemplary embodiments of the present disclosure, which is applied to the screen - casted terminal. Figure 7 The exemplary flow of another screen - casting method is shown, which can be executed by the above - mentioned screen - casted terminal 120 and includes the following steps S710 to S720:

[0083] Step S710, obtain the second data to be screen - casted from the screen - casting terminal. The second data to be screen - casted is obtained by the screen - casting terminal using the display adjustment parameters for the screen - casted terminal to perform display adjustment processing on the first data to be screen - casted. The display adjustment parameters are generated according to the performance information of the screen - casting terminal and the performance information of the screen - casted terminal.

[0084] Step S720, display the corresponding picture according to the second screen projection data.

[0085] Among them, the first data to be projected refers to the initial image data or video data before the display adjustment processing is performed in the projection terminal, and the second data to be projected refers to the data used to send to the projected terminal after the first data to be projected is displayed adjusted according to the display adjustment parameters.

[0086] In this exemplary embodiment, the screen projection terminal can generate display adjustment parameters that adapt to the performance conditions of the projected screen terminal according to the performance information of the screen projection terminal and the performance information of the projected screen terminal. Specifically, the display adjustment parameters can be generated based on the performance information of the screen projection terminal and the performance difference of the projected screen terminal, for example, according to the difference between the brightness information of the display screen of the screen projection terminal and the brightness information of the display screen of the projected screen terminal, the mapping relationship of the brightness information is determined, so that the projected screen terminal can adjust its own brightness to be the same or similar to the brightness information of the screen projection terminal according to the mapping relationship of the brightness information, etc. Further, the screen projection terminal can perform display adjustment processing on the first screen data to be projected according to the determined display adjustment parameters, wherein different display adjustment parameters can have different display adjustment processing methods, for example, the first screen data to be projected can be subjected to color gamut mapping processing, bit depth conversion processing, brightness adjustment data, contrast adjustment processing, etc. Finally, the second screen data to be projected generated after the display adjustment processing can be sent to the projected screen terminal, and after receiving the second screen data to be projected, the projected screen terminal can parse or process it and display the corresponding picture in the display interface of the projected screen terminal. The specific process is similar to that of the above-mentioned screen projection terminal, so it will not be described in detail here.

[0087] In summary, in this exemplary embodiment, the second screen data to be projected is obtained from the projection terminal, and the second screen data to be projected is obtained by the projection terminal performing display adjustment processing on the first screen data to be projected using the display adjustment parameters for the projected terminal, and the display adjustment parameters are generated according to the performance information of the projection terminal and the performance information of the projected terminal; and the corresponding picture is displayed according to the second screen data to be projected. On the one hand, the second screen data to be projected obtained by the projected terminal is obtained by the projection terminal processing the first screen data to be projected according to the display adjustment parameters determined by the performance between the projection terminal and the projected terminal, thereby ensuring the display accuracy and effectiveness when the projected terminal displays based on the second screen data to be projected; on the other hand, while meeting the performance requirements of the projected terminal, the second screen data to be projected can also adjust the screen data to maintain the same or similar display effect as the projection terminal according to the display adjustment parameters, thereby achieving in the projection scenario that when the projected screen data is displayed on the projected terminal, it can retain the display effect consistent with that on the projection terminal as much as possible, thereby improving the user's viewing experience.
