The following describes in detail an image display method and apparatus of an electronic device, and a storage medium provided in the embodiments of the present application with reference to the accompanying drawings.
Example one
The embodiment of the application provides an image display method for an electronic device, and the electronic device may be any device with a folding screen, such as a mobile phone, a tablet computer, and the like, without limitation.
In this example, referring to fig. 1, fig. 1 shows a schematic structural diagram of an electronic device, where the electronic device includes a main control chip 110, an independent display chip 120, and a foldable screen 130, which are electrically connected in sequence.
The main control chip 110 may be a processing chip arranged in the electronic device, such as a CPU, or may be an independent chip arranged separately for implementing the image display method of the present embodiment, which is not limited herein.
In this embodiment, the main control chip 110 is configured to obtain operation data of the electronic device, where the operation data may be information of an application currently opened by the electronic device, may be video data being played, may be shooting data, may also be a screen use state of the folding mobile phone, and the like, and is not limited herein. The independent display chip 120 is configured to display the operation data through the foldable screen 130, where the displayed data may be video data, a web page, a captured image, or the like, and is not limited herein.
In an example, the main control chip 110 may obtain video data from a cloud or locally, and may obtain captured image data from the camera module 140 of the electronic device, the main control chip transfers the video data and the captured data to the independent display chip through a serial protocol transmission interface (DSI-TX 0), the independent display chip receives the video data and the captured data through a serial protocol receiving interface (DSI-RX 0) interface, and transmits the processed video data and the processed captured data to the folding screen through another serial protocol transmission interface (DSI-TX 1), and a user may preview the processed video data and the processed captured data in real time through the folding screen. The Camera module transmits the shooting data to the main control chip through a Camera serial interface transmission 0 (CSI-TX 0), and the main control chip receives the shooting data through a Camera serial interface Receiver0 (CSI-RX 0). In addition, the independent display chip also sends the processed shooting data to the main control chip for storage through another Camera serial interface transmission 1 (CSI-TX 1), so that a user can call the storage data of the main control chip as required to view the shooting data.
Based on the structure of the electronic device, referring to fig. 2, the image display method of the electronic device provided by this example includes:
s201, obtaining data to be displayed of the electronic equipment through the main control chip, and sending the data to be displayed to the independent display chip.
In this embodiment, the data to be displayed of the electronic device may be a movie or short video data or the like obtained from the cloud or locally, or may be a shot image obtained from the camera module. It can be understood that the resolution or the frame rate of the data to be displayed may or may not match with the foldable screen, and therefore, in order to obtain a better display effect, the data to be displayed is sent to the independent display chip through the main control chip.
S202, frame information of data to be displayed is obtained through the independent display chip, target image data are obtained according to the frame information and a first preset condition, and the target image data are sent to the folding screen.
In this embodiment, the frame information of the data to be displayed may include resolution, frame rate, color, noise information, image size, and the like of an image frame of the video or image data.
In one example, the image frames of the adapted display screens may differ between different folded screens, between an unfolded state and a folded state of the same folded screen, for example, the folded screen 130 includes a first display state 301 that may represent that the folded screen is in the folded state as shown in fig. 3 and a second display state 401 that may represent that the folded screen is in the unfolded state as shown in fig. 4. When the folding screen is in the folded state, the display area of the folding screen is smaller than that of the folding screen in the unfolded state, and in the two states, the proportion and the effect of image display can be changed. Therefore, the frame information of the data to be displayed needs to be analyzed and processed to obtain target image data adapted to the display screen, and then the target image data is sent to the folding screen for display through the independent display chip.
In this embodiment, the obtaining, by the independent display chip, the target image data according to the frame information and the first preset condition specifically includes: and taking the data to be displayed as target image data under the condition that the frame information meets a first preset condition. The frame information includes a frame rate or an image resolution of the data to be displayed, and the first preset condition includes that the frame rate of the image data is within a first numerical range, or the image resolution of the image data is within a second numerical range.
That is to say, the frame information of the image frame in the data to be displayed meets the display requirement of the folding screen in the current state, and at this time, the data to be displayed is directly used as the target image data. For example, in the first preset condition, the first numerical range of the frame rate is 40-50fps, and the image frame rate in the data to be displayed is 45fps, which indicates that the video playing data meets the first preset condition.
In this embodiment, under the condition that the frame information does not satisfy the first preset condition, the data to be displayed is processed by the independent display chip, and the processed data to be displayed is used as the target image data, for example, in the first preset condition, if the first numerical range of the frame rate is 40-50fps, and the frame rate in the data to be displayed is 30fps, it is represented that the data to be displayed does not satisfy the first preset condition. Then, the independent display chip performs frame interpolation on the data to be displayed to obtain the data to be displayed after frame interpolation, and the data to be displayed is used as target image data, and it can be understood that the number of image frames of the target image data is within a range of 40-50 fps. Similarly, when the image resolution of the data to be displayed is not in the second data range, the independent display chip obtains the target image data with the image resolution in the second value range by adjusting the resolution of the data to be displayed so as to adapt to the current display state of the folding screen.
It should be noted that the independent display chip includes a processing module, and the processing module is configured to acquire frame information of the data to be displayed, and process the data to be displayed according to the frame information and a first preset condition, so as to obtain target image data. And under the condition that the frame information of the data to be displayed meets the first preset condition, the data to be displayed does not need to be processed, and the independent display chip directly outputs the data to be displayed at the moment. In one example, a bypass may be provided in a separate display chip to accomplish this function. And under the condition that the frame information of the data to be displayed does not meet the first preset condition, the data to be displayed needs to be processed, and at the moment, the independent display chip processes the data to be displayed through the processing module to obtain target image data.
As can be seen from fig. 3 and 4, the folding screen 130 includes a first display state 301 and a second display state 401, and in one example, the folding screen may have two folding axes or three folding axes, etc., that is, in the case where the folding screen supports a multi-folding function, a third display state and a fourth display state, etc., may be included.
In this embodiment, taking the foldable screen 130 as an example including the first display state 301 and the second display state 401, when the foldable screen 130 is in the first display state 301, that is, the folded state, the display area of the foldable screen is inevitably smaller than the display area of the foldable screen in the unfolded state, and therefore, the display requirement of the display screen is relatively low, and therefore, when the foldable screen is in the first display state, the independent display chip directly outputs data to be displayed to the foldable screen, data processing by the processing module is not needed, and power consumption of the electronic device can be reduced.
However, when the foldable screen 130 is in the second display state 401, that is, the unfolded state, the display area is large, and therefore, the display requirement for the display screen is relatively high, and therefore, when the foldable screen is in the second display state, the frame information of the data to be displayed is obtained through the processing module, and the target image data is obtained according to the frame information and the first preset condition.
It should be noted that, in this embodiment, the display state information of the folding screen is acquired through the main control chip, and the display state information is sent to the independent display chip, where the display state information of the folding screen includes a first display state in a folded state and a second display state in an unfolded state.
Specifically, the main control chip may acquire the display state information by monitoring the folding state of the folding screen, or may detect the screen curvature of the folding screen by setting a detection module, obtain the display state information of the folding screen according to the screen curvature, send the display state information of the folding screen to the main control chip by the detection module, the main control chip sends the display state information of the folding screen to the independent display chip, after the independent display chip receives the display state information of the folding screen, open a transmission channel of the target image data according to the display state information, and send the target image data to the corresponding display screen.
In a specific example, the display screen in the folded state is the sub-screen, the display screen in the unfolded state is the main screen, the main control chip sends the photographed image data and the display state information of the folding screen to the independent display chip, the display state information represents that the folding screen is in the folded state, and at this moment, the independent display chip directly sends the image data to the sub-screen. In order to realize image data transmission between the independent display chip and the folding screen, the independent display chip comprises a Mobile Industry Processor Interface (MIPI) switch, hereinafter referred to as MIPI switch, the MIPI switch has a circuit selection function, and the MIPI switch can control a data transmission channel between the independent display chip and the folding screen, for example, a first transmission channel between the independent display chip and the folding screen and a second transmission channel between the independent display chip and the main screen are arranged between the independent display chip and the folding screen, and when display state information of the folding screen sent by the main control chip represents that the folding screen is in a folding state, the MIPI switch can control the first transmission channel to be opened so as to realize target image data transmission in the folding state. When the display state information of the folding screen sent by the main control chip represents that the folding screen is in the unfolded state, the MIPI switch can control the second transmission channel to be opened so as to realize the target image data transmission in the unfolded state of the folding screen.
And S203, displaying the target image data through the folding screen.
In this embodiment, under the condition that the folding screen is in the folded state, the independent display chip transmits the target image data to the folding screen through the first transmission channel, and the folding screen displays the target image data through the auxiliary screen.
And under the condition that the folding screen is in an unfolded state, the independent display chip transmits the target image data to the folding screen through the second transmission channel, and the folding screen displays the target image data through the main screen.
The image display method of the electronic device according to the embodiment of the present invention obtains frame information of data to be displayed through an independent display chip disposed in the electronic device, obtains target image data according to the frame information and a first preset condition, and sends the target image data to the folding screen, so as to improve an image data display effect of the folding screen.
In one scenario, when a user uses the electronic device to perform a video call, the user cannot take a picture, that is, the user needs to hang up the video to take a picture. Considering that the display area of the folding screen is large, the folding screen can be partitioned under the condition that the folding screen is in the second display state, so that the video call and the photographing function can be simultaneously realized, and meanwhile, images in the video call and photographed photos can be respectively processed.
In this scenario, the data to be displayed may include first image data and second image data, and the MIPI switch controls the second transmission channel to be opened, and sends the first image data and the second image data to the main screen together for split-screen display.
In this embodiment, the first image data and the second image data may be of the same data type or different data types, for example, the first image data is video data, the second image data is a shot picture, for example, the first image data is a shot picture, the second image data is also a shot picture, for example, the first image data is video data, and the second image data is also video data, which is not limited herein.
Specifically, under the condition that the folding screen is in the second display state, the display area of the folding screen includes a first screen and a second screen, the corresponding data to be displayed includes first image data and second image data, and the first screen and the second screen are used for displaying the first image data and the second image data.
In the embodiment, the first frame information of the first image data is acquired through the independent display chip, and the second frame information of the second image data is acquired; the independent display chip obtains a first target sub-image according to the first frame information and a first preset condition, and the independent display chip obtains a second target sub-image according to the second frame information and the first preset condition; the first screen and the second screen are used for displaying a first target sub-image and a second target sub-image of the first target sub-image.
In one example, the areas of the first screen and the second screen may be equal, that is, the display area of the folded screen in the unfolded state is divided into two equal parts, or the display area of the folded screen in the unfolded state is divided into two unequal parts as the first screen and the second screen for displaying the first target sub-image and the second target sub-image, respectively.
In the embodiment, display coordinate information corresponding to data to be displayed is acquired through a main control chip, the display coordinate information is sent to an independent display chip, the display coordinate information is associated with a first target sub-image and a second target sub-image through the independent display chip, and the associated first target sub-image and second target sub-image are sent to a folding screen; the display coordinate information comprises first screen coordinate information used for displaying the first sub-image and second screen coordinate information used for displaying the second sub-image.
For example, the data sent by the main control chip to the independent display chip are first image data, a first display coordinate, second image data and a second display coordinate, wherein the first display coordinate corresponds to the display range of the first screen, and the second display coordinate corresponds to the display range of the second screen. Then, the independent display chip obtains a first target sub-image according to the first image data, obtains a second target sub-image according to the second image data, associates the first target sub-image with the first display coordinate so that the first target sub-image can be displayed in the display range of the first screen, and associates the second target sub-image with the second display coordinate so that the second target sub-image can be displayed in the display range of the second screen. In one embodiment of the present application, the coordinates of the folding screen may be represented by X2200 × X2200, where X0 to X1100 are defined as a first screen for displaying the first image data, and X1100 to X2200 are defined as a second screen for displaying the second image data, so as to realize that different operation data have specific display areas.
In another example, according to the difference between the attributes of the real-time video data and the shooting data, the first image data and the second image data are respectively provided with tags, the first screen and the second screen are also provided with corresponding tags, the first image data and the first screen are associated by the tags, and the second image data and the second screen are associated by the tags. Therefore, the effect of displaying different contents in a split screen mode is achieved, the display area of the display screen can be reasonably utilized, and the display efficiency is improved.
The above is an implementation manner of the image display method of the electronic device provided by this embodiment, and different image data can be displayed in a split screen manner when the folding screen is in the unfolded state, so as to improve an application scene of the folding screen terminal and improve user experience.
In another scenario, when the display contents in the first screen and the second screen are different, considering the display effect requirement and the environment requirement of different image data, for example, due to the influence of factors such as ambient light, in the case of real-time video and photographing, the influence of image noise and brightness on the display effect of the image data is large, and therefore, the first preset condition of the embodiment further includes that the noise value of the image data is within a third numerical range, or the brightness value of the image data is within a fourth numerical range.
In this embodiment, the obtaining, by the independent display chip, the first target sub-image according to the first frame information and the first preset condition includes: taking the first image data as a first target sub-image under the condition that the first frame information meets a first preset condition; under the condition that the first frame information does not meet a first preset condition, the independent display chip is used for processing the first image data, the processed first image data is used as a first target sub-image, the independent display chip is used for processing the first image data, and the processing comprises brightening, noise reduction and the like on the first image data, so that a good display effect is obtained.
Similarly, the independent display chip obtains a second target sub-image according to the second frame information and the first preset condition, and the method includes: taking the second image data as a second target sub-image under the condition that the second frame information meets a first preset condition; and under the condition that the second frame information does not meet the first preset condition, processing the second image data through the independent display chip, and taking the processed second image data as a second target sub-image.
It should be noted that, in this embodiment, the first image data in the first screen and the second image data in the second screen may be processed simultaneously, or one of the first image data and the second image data may be processed separately.
In the embodiment of the present application, the first numerical range, the second numerical range, the third numerical range, and the fourth numerical range may be set by a developer, or may be set by a user in a user-defined manner.
The above is an image display method of an electronic device in the embodiment, where the folding screen is in the unfolded state, and any image data in the first screen and the second screen can be processed to obtain target image data meeting a first preset condition, so as to enhance an applicable scene of the folding screen and improve image display efficiency.
It can be understood that, in the process of performing a video call, since the video is displayed in real time, the video call generally has no need for storage, and the real-time video data can be stored by an independent display chip, so that the real-time video data is displayed by a folding screen, or the preview of the target shot image is performed. However, the shot image needs to be stored in the electronic device, such as an album of the smart terminal.
Therefore, after the target image data is obtained, the present embodiment further sends the target image data to the main control chip through the independent display chip, and stores the target image data through the main control chip, where the main control chip includes a storage module. So that the target image data can be stored in the electronic device, and the user can edit and share the target image data at a later stage. The target image data includes a shot picture, and of course, may also include video data, for example, in the case where a user records real-time video data through system settings, the video data may also be stored.
