[0043] In addition, the electronic device also includes other modules such as a Wi-Fi module 25 and a random access memory 26. The Wi-Fi module 25, the random access memory 26 and other modules can be electrically connected to the processor chip 21 and can exchange information with the processor chip 21.

[0044] For example, through Figure 2 In the process of taking pictures in the electronic device shown, the image captured by the camera module 23 is transmitted back to the processor chip 21 through the second camera receiving interface 214, and the image on the processor chip 21 side can be electrically connected to the first receiving interface 221 through the first output interface 211 to send the picture to the independent display chip 22.

The processor chip 21 can store the picture processed by the independent display chip 22 for subsequent use, and the display module 24 can display the picture processed by the independent display chip 22 in real time, so as to achieve the purpose of optimizing the display effect of the captured picture.

[0045] It is understandable that all functions of the processor chip 21 can be executed by the application processor of the processor chip 21, and the first output interface 211, the second output interface 212, the first camera receiving interface 213 and the second camera receiving interface 214 included in the processor chip 21 are all electrically connected to the application processor, and the application processor processes all data. In addition, the independent display chip 22 may also include other interfaces to realize other functions of the independent display chip 22.

[0046] like Figure 3 As shown, the embodiment of the present application also provides an independent display chip, and the independent display chip 22 can be applied to Figure 2 The electronic device shown in the figure, and the independent display chip 22 includes a first preprocessing module 225, a second preprocessing module 226, a first receiving interface 221, a second receiving interface 222 and a camera output interface 223, the first receiving interface 221 and the second receiving interface 222 are electrically connected to the input end of the first preprocessing module 225, respectively, the output end of the first preprocessing module 225 is electrically connected to the input end of the second preprocessing module 226, and the camera output interface 223 can be electrically connected to the output end of the first preprocessing module 225 or the output end of the second preprocessing module 226;

[0047] Among them, when the camera output interface 223 is electrically connected to the output end of the second preprocessing module 226, the camera output interface 223 is used to return the target content to the processor chip, and the target content is based on the multimedia content received by the first receiving interface 221 and the user interface content received by the second receiving interface 222 after being processed in sequence by the first preprocessing module 225 and the second preprocessing module 226.

[0048] In this embodiment, the overlay function of the second preprocessing module 226 of the independent display chip 22 can be utilized, and the display content including the user interface content and multimedia content after color enhancement processing after the overlay processing by the second preprocessing module 226 can be directly used as the target content, and the return function of the camera output module 223 can be utilized to return the target content to the processor chip 21, so that the processor chip 21 performs the screen projection operation based on the target content, which can effectively avoid the overlay processing of multimedia content (such as screen projection content) and user interface content on the processor chip 21 side, and effectively reduce the workload of the processor chip 21; in addition, it can also reduce the power consumption and delay of the processor chip 21, and effectively improve the working performance of the processor chip.

[0049] The independent display chip 22 further includes a display output interface 224 , and the display output interface 224 is used to transmit the target content obtained after being processed by the first pre-processing module 225 and the second pre-processing module 226 in sequence to the display module 24 for display.

[0050] Further optionally, the camera output interface 223 and the output end of the second preprocessing module 226 may be electrically connected via a first switch 227 , that is, the camera output interface 223 and the output end of the second preprocessing module 226 may be turned on or off via the first switch 227 .

[0051] The first switch 227 may be any one of a bipolar transistor and a field effect transistor.

[0052] Optionally, the first switch 227 may also be integrated at the output end of the second pre-processing module 226 .

[0053] In addition, a second switch may also be set at the output end of the first preprocessing module 225 so that the first preprocessing module 225 can control the conduction or cutoff of the camera output interface 223 and the output end of the first preprocessing module 225 through the second switch. The second switch may also be any one of a bipolar transistor and a field effect transistor.

[0054] like Figure 1 As shown, the screen projection processing method provided in the embodiment of the present application includes the following steps:

[0055] Step 101: Send the content to be projected from the processor chip to the independent display chip.

[0056] In this step, the content to be projected can be sent from the processor chip to the independent display chip through the first output interface of the processor chip and the first receiving interface of the independent display chip, so that the content to be projected can be processed by the independent display chip and the display quality of the content to be projected can be improved.

[0057] Among them, the content to be projected can be understood as the content that the user wants to project, such as pictures, videos and other multimedia content.

[0058] Step 102: pre-process the content to be projected through the independent display chip to obtain target projected content.

[0059] In this step, the independent display chip pre-processes the content to be projected, including but not limited to at least one of interpolation processing, noise reduction processing, super-resolution processing, color enhancement processing, and overlay processing, so as to achieve the purpose of improving the display quality of the content to be projected.

[0060] Step 103: transmit the target projection content from the independent display chip back to the processor chip.

[0061] In this step, the feedback function of the camera output interface of the independent display chip can be utilized to transmit the content to be projected that has been pre-processed by the independent display chip, that is, the target projection content, back to the processor chip through the camera output interface.

[0062] Step 104: Perform a screen projection operation based on the target screen projection content.

[0063] In this step, executing the screen projection operation can be understood as projecting the target screen content to the TV, curtain wall, etc. Moreover, by using the target screen content obtained after preprocessing by the graphics card chip as the screen projection content, the frame rate, resolution, color effect, etc. of the screen projection content can be effectively improved, thereby achieving the purpose of improving the display quality of the content to be projected.

[0064] Thus, in the present application, by utilizing the feedback function of the camera output interface of the independent display chip, the content to be projected transmitted to the independent display chip is preprocessed by the preprocessing function of the independent display chip, and the preprocessed content to be projected is returned to the processor chip through the feedback function of the camera output interface, thereby achieving the purpose of preprocessing the content to be projected on the processor chip side, and then achieving the purpose of improving the display quality of the content to be projected, and making the content to be projected preprocessed by the independent display chip have better display quality.

[0065] Optionally, preprocessing the to-be-projected screen content by the independent display chip to obtain target projected screen content includes:

[0066] Performing a first preprocessing on the screen content to be projected and the user interface content through a first preprocessing module of the independent display chip, and obtaining a first screen content and a first user interface content, wherein the user interface content is sent from the processor chip to the independent display chip;

[0067] Determine the first projection content as the target projection content.

[0068] The user interface content can be sent from the processor chip to the independent display chip through the second output interface of the processor chip and the second receiving interface of the independent graphics chip.

[0069] In this embodiment, the first pre-processing module can be understood as a pre-function processing module inside an independent display chip, which is mainly used to perform frame insertion, noise reduction, super-resolution and other processing on the display content to improve the frame rate, resolution and other aspects of the display content. That is, by performing the first pre-processing on the content to be projected and the user interface content, the purpose of improving the frame rate, resolution and other aspects of the content to be projected and the user interface content can be achieved, and the purpose of improving the display quality of the content to be projected and the user interface content can be achieved.

[0070] Among them, the user interface content can be understood as the content of the user interface layer of the display interface, such as barrage and the like.

[0071] Moreover, by determining the first projection content as the target projection content, that is, determining the content to be projected after the first pre-processing (including but not limited to interpolation processing, noise reduction processing, and super-resolution processing) as the target projection content, the purpose of improving the display quality of the projection content can be achieved.

[0072] Further optionally, after performing a first preprocessing on the screen content to be projected and the user interface content by the first preprocessing module of the independent display chip and obtaining the first screen content and the first user interface content, the method further includes:

[0073] The first projection screen content and the first user interface content are subjected to a second preprocessing by the second preprocessing module of the independent display chip, and a target projection screen content is obtained, and the target projection screen content at least includes the first projection screen content and the first user interface content after overlay processing.

[0074] In this embodiment, the second preprocessing module can be understood as a post-function processing module inside the independent display chip, which mainly performs color enhancement processing on the user interface content and the first projection content, and superimposes the user interface content after color enhancement processing and the first projection content, so as to pass the superimposed display content to the display module, thereby achieving the purpose of improving the display effect of the display content through the preprocessing of the independent display chip. That is, by performing the second preprocessing on the first projection content and the first user interface content, the purpose of improving the color effect of the first projection content and the first user interface content can be achieved, and by superimposing the first user interface content after color enhancement processing and the first projection content, the target projection content including the first user interface content and the first projection content after color enhancement processing and superimposed can be obtained. Even if the target projection content includes not only the information corresponding to the first projection content but also the information corresponding to the first user interface content, the purpose of enriching the projection effect of the target projection content can be achieved.

[0075] In this way, the target projection content obtained by superimposing the user interface content after color enhancement processing and the first projection content includes not only the information corresponding to the first projection content but also the information corresponding to the first user interface content (such as the barrage information of the user interface layer), thereby achieving the purpose of enriching the projection effect of the target projection content.

[0076] Optionally, performing the screen projection operation based on the target screen projection content includes:

[0077] The first projection screen content and the user interface content are superimposed to obtain the projection screen content after superimposition processing, and a projection operation is performed based on the projection screen content after superimposition processing.

[0078] In this implementation, on the processor chip side, user interface content (such as barrage information on the user interface layer) can also be superimposed on the basis of the first projection content to achieve the purpose of enriching the projection effect of the target projection content.

[0079] It should be noted that by utilizing the overlay function of the second preprocessing module of the independent display chip, the display content including the first user interface content after color enhancement processing and the first projection screen content after the overlay processing by the second preprocessing module can be directly used as the target projection screen content, and the feedback function of the camera output module can be utilized to transmit the target projection screen content back to the processor chip, so that the processor chip can perform the projection operation based on the target projection screen content, which can effectively avoid the overlay processing of the projection screen content and the user interface content on the processor chip side, and effectively reduce the workload of the processor chip; in addition, it can also reduce the power consumption and delay of the processor chip, and effectively improve the working performance of the processor chip.

[0080] It is understandable that the screen projection operation can be performed using the Wi-Fi module of the electronic device. Moreover, the screen projection operation can also be performed using the Bluetooth module, 5G / 4G network, etc. of the electronic device.

[0081] The screen projection processing method of the embodiment of the present application is as follows: the screen content to be projected is sent from the processor chip to the independent display chip; the screen content to be projected is preprocessed by the independent display chip to obtain the target screen content; the target screen content is transmitted back from the independent display chip to the processor chip; and the screen projection operation is performed based on the target screen content. In this way, the feedback function of the camera output interface of the independent display chip is utilized so that the screen content to be projected transmitted to the independent display chip is preprocessed by the preprocessing function of the independent display chip, and the preprocessed screen content to be projected is transmitted back to the processor chip through the feedback function of the camera output interface, thereby achieving the purpose of preprocessing the screen content to be projected on the processor chip side, and then achieving the purpose of improving the display quality of the screen content to be projected, and making the screen content to be projected preprocessed by the independent display chip have better display quality.
