Fig. 3 shows an exemplary flow of a screen projection method, which may be executed by the screen projection terminal 110, and includes the following steps S310 to S340:
and step S310, acquiring the performance information of the screen-projected terminal.
The performance information of the screen-projected terminal may include various performance information in hardware or software of the screen-projected terminal, for example, display performance information of a display screen of the screen-projected terminal, and hardware performance information such as performance information of a processor, or software performance information such as parameter data set by a user in the screen-projected terminal. Specifically, the performance information may include display performance information and processor performance information, wherein the display performance information may include one or more of color gamut information, brightness information, contrast information, or bit depth information of the display screen, and the processor performance information may include an effect mapping relationship of the processor source image data to the display screen, information supporting an image display or video playback format, and the like.
In this exemplary embodiment, when the connection between the screen-projected terminal and the screen-projected terminal is established, the screen-projected terminal may actively send the performance information to the screen-projected terminal, so that the screen-projected terminal can receive the performance information in time. In addition, in an exemplary embodiment, the step S310 may include the following steps:
sending a performance information query request to a screen-projected terminal;
and responding to the screen-projected terminal to receive the performance information query request, and receiving the performance information returned by the screen-projected terminal.
That is, after the connection between the screen-projected terminal and the screen-projected terminal is established, the screen-projected terminal has a requirement for acquiring performance information of the screen-projected terminal, or actively requests the performance information from the screen-projected terminal, the screen-projected terminal sends the performance information to the screen-projected terminal, so as to improve the effectiveness and efficiency of sending the performance information. Specifically, the screen projection terminal may send a performance information query request to the screen projection terminal after establishing connection with the screen projection terminal, where the request may be a simple instruction request requesting to obtain performance information, or may also be a detailed request including which performance information or performance information needs to be obtained, and after receiving and responding to the performance information query request, the screen projection terminal may return corresponding performance information to the screen projection terminal.
It should be noted that, in this exemplary embodiment, the number of the screen-projected terminals may be multiple, when there are multiple screen-projected terminals, the multiple screen-projected terminals may send respective performance information to the screen-projected terminals, and the screen-projected terminal may also send a performance information query request to one or more of the screen-projected terminals according to actual requirements, so as to obtain performance information of some of the screen-projected terminals, and the like, which is not specifically limited in this disclosure.
And step S320, generating display adjustment parameters aiming at the screen-projected terminal according to the performance information of the screen-projected terminal and the performance information of the screen-projected terminal.
Generally, due to different terminal device performance information, when images or videos are displayed on different terminal devices, different display effects, such as color, color temperature, brightness or contrast effect, are presented. In order to enable the screen-projected terminal to have a consistent or similar display effect with the screen-projected terminal, the exemplary embodiment may generate a display adjustment parameter adapted to the performance condition of the screen-projected terminal according to the performance information of the screen-projected terminal and the performance information of the screen-projected terminal. Specifically, the display adjustment parameter may be generated based on a difference between performance information of the screen projecting terminal and performance of the screen projected terminal, for example, a mapping relationship of luminance information is determined according to a difference between luminance information of a display screen of the screen projecting terminal and luminance information of a display screen of the screen projected terminal, so that the screen projected terminal may adjust a state that luminance of the screen projected terminal is the same as or similar to the luminance information of the screen projecting terminal according to the mapping relationship of the luminance information, and the like.
And step S330, performing display adjustment processing on the first screen data to be projected by using the display adjustment parameters to obtain second screen data to be projected.
The first screen data to be projected refers to initial image data or video data and the like before display adjustment processing is not performed in the screen projection terminal, and the second screen data to be projected refers to data which is used for sending to the screen projection terminal after the display adjustment processing is performed on the first screen data to be projected according to the display adjustment parameters.
In the present exemplary embodiment, the display adjustment processing may be performed on the first to-be-projected-screen data according to the determined display adjustment parameter, and specifically, the display adjustment processing may include multiple types, for example, performing color gamut mapping processing, bit depth conversion processing, brightness adjustment data, contrast adjustment processing, and the like on the first to-be-projected-screen data according to different display adjustment parameters.
And step S340, sending the second screen data to be projected to the screen terminal to be projected, so that the screen terminal to be projected displays the corresponding picture according to the second screen data to be projected.
Finally, the second screen data to be projected after the display adjustment processing can be sent to the screen terminal to be projected, so that the screen terminal to be projected can display corresponding pictures, wherein it should be noted that the second screen data to be projected represents data for picture display at the screen terminal to be projected, and "second" does not represent quantity. When the screen-projected terminals with the same performance information exist, the display adjustment processing process can be performed according to the performance information of one of the screen-projected terminals, and the screen-projected terminals with the same performance information are multiplexed into other screen-projected terminals with the same performance information. In addition, the screen projection terminal can also zoom the display picture corresponding to the generated second screen data to be projected to a state in accordance with the proportional relation of the display picture of the screen projected terminal, for example, zoom according to the aspect ratio of the display picture of the screen projected terminal, and send the processed second screen data to be projected to the screen projected terminal for picture display, so as to ensure that the proportional relation of the picture has a good display effect on the screen projected terminal.
It should be noted that the second screen data to be projected is data which is adapted to the performance of the screen terminal to be projected after being processed by the first screen data to be projected and has the same or similar data display effect as the screen terminal itself, and when the performance information of the screen terminal to be projected is higher than the performance information of the screen terminal to be projected, the generated display adjustment parameter can enable the adjusted second screen data to be projected to have the same display effect as the first screen data to be projected when being displayed, for example, when a screen image to be projected is displayed at the screen terminal to be projected, the image displayed by the screen terminal has the same brightness, contrast and the like; when the performance information of the screen-projected terminal is lower than the performance information of the screen-projected terminal, the generated display adjustment parameter can enable the adjusted second screen-to-be-projected data to have an approximate display effect with the first screen-to-be-projected data when being displayed, for example, the range of the brightness parameter of the screen-projected terminal is smaller than the range of the brightness parameter of the screen-projected terminal, when the brightness parameter of the first screen-to-be-projected data is higher than the upper limit of the brightness parameter which can be reached by the screen-projected terminal, the display adjustment parameter can be generated according to the brightness information of the screen-projected terminal, the first screen-to-be-projected data is processed based on the display adjustment parameter, so that the generated second screen-to-be-projected data is close to the brightness of the first screen-to-be-projected data as much as possible, thereby on one hand, the consistency of the screen display of the screen-projected terminal and the screen-projected terminal is realized, on the other hand, when the performance of the screen-projected terminal is weaker than the screen-projected terminal, the image quality effect of the display picture of the projected terminal is improved to a certain extent.
To sum up, in the present exemplary embodiment, the performance information of the screen-projected terminal is acquired; generating display adjustment parameters aiming at the screen-projected terminal according to the performance information of the screen-projected terminal and the performance information of the screen-projected terminal; performing display adjustment processing on the first screen data to be projected by using the display adjustment parameters to obtain second screen data to be projected; and sending the second screen data to be projected to the screen terminal to be projected, so that the screen terminal to be projected displays the corresponding picture according to the second screen data to be projected. On one hand, the exemplary embodiment provides a new screen projection method, which determines a display adjustment parameter according to performance information between a screen projection terminal and a screen projection terminal, so as to process the display adjustment of the screen data to be projected through the display adjustment parameter, and since the display adjustment parameter is 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, and the accuracy and effectiveness of the display adjustment of the screen data to be projected are ensured; on the other hand, in the exemplary embodiment, the acquired performance information of the screen-projected terminal is used as a reference, the display adjustment parameter for the screen-projected terminal is generated, the display adjustment of the first to-be-projected-screen data is adjusted based on the display adjustment parameter, the performance condition of the screen-projected terminal is fully considered, and the display adjustment processing process is adaptive to the performance of the screen-projected terminal, so that the generated second to-be-projected-screen data can be adaptively adjusted during display; in addition, the second screen data to be projected can be adjusted to the same or similar display effect as the screen projection terminal according to the display adjustment parameters while meeting the performance requirements of the screen projection terminal, so that the display effect consistent with that of the screen projection terminal can be kept as far as possible when the screen projection terminal displays the screen projection data in the screen projection scene, and the viewing experience of a user is improved.
In an exemplary embodiment, as shown in fig. 4, the performance information may include display performance information, and the step S320 may include the steps of:
and step S410, generating display mapping parameters aiming at the screen-projected terminal according to the display performance information of the screen-projected terminal and the display performance information of the screen-projected terminal, wherein the display adjusting parameters comprise the display mapping parameters.
Further, the step S330 may include:
step S420, performing numerical mapping on one or more display parameters in the first screen data to be projected by using the display mapping parameters to obtain second screen data to be projected.
Considering that the display performance standards or parameter ranges of different terminals are not consistent, data calculation is performed through a simple incremental relation, and the method can be hardly suitable for all application scenarios. Therefore, in order to enable the screen to have the same or similar display effect in terms of screen color gamut, contrast, brightness, or the like between the projected terminal and the projected terminal, the present exemplary embodiment may generate a display mapping parameter for the projected terminal according to a difference between the display performance information of the projected terminal and the display performance information of the projected terminal, where the display mapping parameter may refer to a mapping relationship that needs to achieve the same or similar display effect between the terminals, and may be determined according to a mapping relationship of parameter intervals of display performance between different terminals, for example, a luminance parameter interval of the projected terminal is [ a, b ], a luminance parameter interval of the projected terminal is [ c, d ], and a mapping parameter for converting fixed luminance between different intervals is determined through the luminance parameter intervals of the two terminals. Through the display mapping parameters, display parameter mapping can be carried out on the first screen data to be projected of the screen projection terminal, so that the generated second screen data to be projected is consistent with the display effect of the screen projection terminal when being displayed by the screen projection terminal.
When the display adjustment processing is performed on the first to-be-projected-screen data by using the display mapping parameters, the present exemplary embodiment may select to perform numerical mapping on one or more display parameters in the first to-be-projected-screen data, for example, the first to-be-projected-screen data may include different display parameters such as brightness, contrast, and bit depth, may perform numerical mapping on brightness, contrast, or brightness and contrast in the display parameters according to actual requirements, and may also perform numerical mapping on all display parameters included therein to meet the calculation requirements of different scenes, for example, in a scene with a low requirement on some display parameters, the numerical mapping of some display parameters may be selected to be omitted to improve the calculation efficiency and reduce the system calculation amount.
In an exemplary embodiment, as shown in fig. 5, the screen projection method may further include the following steps:
step S510, acquiring the size of a display area and the size of an interaction area of the projected terminal, wherein the interaction area is positioned in the display area;
in step S330, performing display adjustment processing on the first to-be-projected-screen data by using the display adjustment parameter may include:
step S520, performing display adjustment processing on the first to-be-projected-screen data according to the size relationship between the size of the display area and the size of the interaction area and the display adjustment parameter.
The interactive area refers to an area which can be interactively operated and controlled by a user in a display interface of the screen-projected terminal, for example, after the screen-projected terminal projects a picture comprising a game application program and a chat application program which are displayed in a split screen mode to the screen-projected terminal, wherein when the user operates the game application program, the area where the game application program is located is the interactive area; or the screen projection terminal zooms the display area of a certain application program and places the display area at a position of a certain sub-area in the display interface, then the position of the sub-area of the application program in the display interface is the interactive area after the current display picture is projected to the screen projection terminal, and the area which can be interactively operated and controlled with a user in the display interface can be used as the interactive area. The interaction area may be a display area of the whole screen-projected terminal, for example, when a display screen of an application program is projected to the screen-projected terminal, a user interacts with the current display area, and then all interfaces of the current display area are also the interaction area; for example, when a user interacts with one of the application programs when a display screen on which a plurality of application programs are opened is projected onto the projected terminal, the sub-area of the display area where the interacted application program is located is the interaction area. As shown in fig. 6, the area 610 is a display area of the projected terminal, that is, a screen projection area of the screen, where either the area S or the area P may be used as an interaction area. In this exemplary embodiment, the screen projection terminal may send a request instruction for the size of the display area and the size of the interaction area to the screen projected terminal through the network link, and after the screen projected terminal receives and responds to the request instruction, return corresponding size information. Further, the screen projection terminal can determine how to perform display adjustment processing on the first screen data to be projected according to the display adjustment parameter according to the received size relationship between the size of the display area and the size of the interaction area.
In an exemplary embodiment, the step S520 may include the following steps:
if the size of the display area is larger than that of the interaction area, performing display adjustment processing on data corresponding to the interaction area in the first screen data to be projected according to the display adjustment parameters;
and if the size of the display area is equal to that of the interactive area, performing display adjustment processing on the display area or data corresponding to the interactive area in the first to-be-projected-screen data according to the display adjustment parameters.
In this exemplary embodiment, if the size of the display area is larger than the size of the interaction area, it is described that the user interacts with only a part of the sub-area of the display area, at this time, in order to reduce the calculation amount of the display adjustment processing and improve the efficiency of the display adjustment processing, and in order to highlight an area with a closer interaction relationship with the current user, the exemplary embodiment may select to perform the display adjustment processing on only the data corresponding to the interaction area in the first screen data to be projected by using the display adjustment parameter. If the size of the display area is equal to the size of the interactive area, it is indicated that the user can perform interactive operation with the whole area where the current display interface is located, at this time, display adjustment processing can be performed on the complete first screen data to be projected, specifically, display adjustment processing can be performed on data corresponding to the display area in the first screen data to be projected, or display adjustment processing can be performed on data corresponding to the interactive area in the first screen data to be projected.
In an exemplary embodiment, before sending the second data to be screen-projected to the terminal to be screen-projected, the screen-projecting method may further include the following steps:
when the screen-projected terminal supports the high dynamic range mode, processing the second screen-to-be-projected data into a data format corresponding to the high dynamic range mode, and sending the data format to the screen-projected terminal;
and when the screen-projected terminal does not support the high dynamic range mode, processing the second screen-to-be-projected data into a data format corresponding to the standard dynamic range mode, and sending the data format to the screen-projected terminal.
In this exemplary embodiment, if the processor of the screen-projected terminal supports the high dynamic range mode, when the screen-projected terminal sends the second to-be-projected-screen data, the second to-be-projected-screen data may be processed into a data format corresponding to the high dynamic range mode, and then sent to the screen-projected terminal, so as to ensure that after the second to-be-projected-screen data is sent to the screen-projected terminal, a better picture effect can be displayed according to the performance mode of the screen-projected terminal. If the processor of the screen-projected terminal does not support the high dynamic range mode, the screen-projected terminal can directly process the second screen-to-be-projected data into a data format corresponding to the standard dynamic range mode when sending the second screen-to-be-projected data, and then send the second screen-to-be-projected data to the screen-projected terminal.

In this exemplary embodiment, the screen projection terminal may generate a display adjustment parameter adapted to a performance condition of the screen projected terminal according to the performance information of the screen projection terminal and the performance information of the screen projected terminal. Specifically, the display adjustment parameter may be generated based on a difference between performance information of the screen projecting terminal and performance of the screen projected terminal, for example, a mapping relationship of luminance information is determined according to a difference between luminance information of a display screen of the screen projecting terminal and luminance information of a display screen of the screen projected terminal, so that the screen projected terminal may adjust a state that luminance of the screen projected terminal is the same as or similar to the luminance information of the screen projecting terminal according to the mapping relationship of the luminance information, and the like. Further, the screen projection terminal may perform display adjustment processing on the first to-be-projected-screen data according to the determined display adjustment parameter, where different display adjustment parameters may have different display adjustment processing modes, for example, color gamut mapping processing, bit depth conversion processing, brightness adjustment data, contrast adjustment processing, and the like may be performed on the first to-be-projected-screen data. Finally, the second screen data to be projected generated after the display adjustment processing can be sent to the screen terminal to be projected, and the screen terminal to be projected can analyze or process the second screen data to be projected after receiving the second screen data to be projected, and display a corresponding picture in a display interface of the screen terminal to be projected. The specific process is similar to the process of the screen projection terminal, and is not described in detail herein.
