Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular, to a wallpaper setting method for a folding screen device and a folding screen device. Background Art

[0002] With the development of technology, foldable screen devices are becoming more and more the focus of industry research. As the name implies, a foldable screen device is an electronic device with a foldable screen. By folding the screen, the size of the device can be reduced and the portability of the device can be improved. When the screen is unfolded, the originally folded screen can form a larger screen area, which is convenient for users to use; or, users can also fold the screen to a certain angle to form different split-screen forms to enrich the functions of the device.

[0003] Typically, the screen of a folding screen device includes an outer screen and an inner screen, and the size of the outer screen is often smaller than the inner screen. When in use, the inner and outer screens of different sizes can be used to display different information respectively. Similar to ordinary electronic devices, users can also set wallpapers for the inner and outer screens of folding screen devices. Taking a folding mobile phone as an example, when a user sets the screen wallpaper on a folding mobile phone, it is necessary to set it separately on the outer screen and inner screen of different sizes. Due to the different sizes of the inner and outer screens, if the folding screen device cuts the wallpaper in the same way, the integrity and aesthetics of the wallpaper cannot be guaranteed. After the wallpaper is set, the final effect on the inner and outer screens may also be quite different. Summary of the invention

[0004] The embodiments of the present application provide a wallpaper setting method for a folding screen device and a folding screen device, which are used to solve the problem in the prior art that when setting the wallpaper of the inner and outer screens of the folding screen device, they are cut in the same way, which affects the integrity and aesthetics of the wallpaper.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a method for setting wallpaper for a folding screen device is provided, comprising: identifying a main object in an image; cropping the image to obtain multiple wallpaper images adapted to the respective screens according to the position of the main object in the image and the size information of the respective screens of the folding screen device; wherein the sizes of the respective screens are different, and the main object is included in any wallpaper image; and setting each wallpaper image as the wallpaper of the adapted screen.

[0007] By applying the wallpaper setting method provided in the embodiment of the present application, when setting wallpaper for each screen of a folding screen device, the main object in the image can be first identified, and then the image can be cropped according to the position of the main object in the image and the size information of each screen of the folding screen device to obtain multiple wallpaper images. Since each wallpaper image is obtained by cropping the main object in the image according to the size information of a certain screen, it can not only ensure that the cropped wallpaper image contains the main object in the original image, but also make the resolution of each wallpaper image match the size of the corresponding screen. After setting each wallpaper image as the wallpaper of the corresponding screen, the main features of the original image can be retained to the maximum extent. The wallpaper setting method provided in the embodiment of the present application can solve the problem in the prior art that cropping along the middle of the image for screens of any size can easily destroy the integrity of the main object in the image, reduce the possibility of large differences in the final effects of the wallpaper image on the inner and outer screens, and improve the aesthetics and uniformity of the screen wallpaper of the folding screen device.

[0008] It should be understood that the above-mentioned size information may refer to the size, aspect ratio or resolution of the screen or wallpaper image.

[0009] In a possible implementation of the first aspect, according to the position of the subject in the image and the size information of each screen of the folding screen device, the image is cropped to obtain multiple wallpaper images adapted to each screen, including: according to the position of the subject in the image, determining the image area containing the subject; according to the size information of each screen of the folding screen device, cropping the image to obtain multiple wallpaper images adapted to each screen. By determining the area where the subject is located and using it as the image area to be retained, it can be ensured that the image is accurately cropped during the wallpaper setting process, and the subject in the image is retained.

[0010] In a possible implementation of the first aspect, an image is cropped according to size information of each screen of a folding screen device to obtain multiple wallpaper images adapted to each screen, including: determining a folding method of the folding screen device, the folding method including horizontal folding or vertical folding, and any folding method corresponds to a cropping direction; the image is cropped according to the cropping direction corresponding to the folding method to obtain multiple wallpaper images, wherein each wallpaper image obtained by cropping has the same aspect ratio as the adapted screen.

[0011] It should be understood that different types of folding screen devices have different folding methods. For folding screen devices with different folding methods, different solutions can be used when cutting wallpaper.

[0012] For example, if the folding mode of the folding screen device is horizontal folding, a wallpaper image having the same aspect ratio as the adapted screen is cut out from the image in a vertical cutting mode; if the folding mode of the folding screen device is vertical folding, a wallpaper image having the same aspect ratio as the adapted screen is cut out from the image in a horizontal cutting mode. In this way, the adaptability of the cut wallpaper image to the corresponding screen can be improved.

[0013] In a possible implementation manner of the first aspect, the image is cropped according to a cropping direction corresponding to the folding manner to obtain multiple wallpaper images, including:

[0014] In a possible implementation of the first aspect, each screen of the folding screen device includes a first screen whose size information is smaller than a preset value. The image is cropped according to the position of the subject in the image and the size information of each screen of the folding screen device to obtain multiple wallpaper images adapted to each screen, further comprising: determining the position of the main part of the subject in the image; cropping the image according to the size information of the first screen to obtain a first wallpaper image including the main part of the subject and adapted to the first screen.

[0015] Exemplarily, the first screen may be an outer screen of a foldable screen device. When cropping a wallpaper image for the outer screen, if an image containing target features of a subject cannot be cropped from the image according to the size of the outer screen, the foldable screen device may crop only the main part of the subject in the image.

[0016] It should be understood that the main object may include multiple parts, and the priorities of different parts may be different. The main part of the main object may have the highest priority. For the smaller external screen of the folding screen device, the main part of the main object in the image may be retained by cropping the image to retain the main part of the main object in the image, so that the main features of the main object can be retained in the wallpaper image to the greatest extent.

[0017] In a possible implementation of the first aspect, after identifying the main object in the image, it also includes: determining the center point of the main object; based on the center point, determining the area in the image containing the target features of the main object as the image area that needs to be retained.

[0018] In a possible implementation of the first aspect, after determining the region containing the target features of the subject in the image as the image region to be retained, the method further includes: displaying prompt box information for the image region to be retained on any screen of the folding screen device, and the prompt box information can be used to prompt the user to adjust the image region to be retained. When receiving an operation on the prompt box information, the folding screen device can adjust the size and / or position of the image region to be retained according to the operation.

[0019] Here, the target features of the subject object may be all features representing the entire subject object (also called the complete features of the subject object), or features identifying some protruding parts of the subject object (also called the complete features of some parts of the subject object), etc.

[0020] It should be understood that the image area that needs to be retained determined by the folding screen device according to the algorithm may not be the image area that the user actually wants to retain. By displaying a prompt box on the screen, the user can be prompted to adjust the image area that needs to be retained. For example, enlarge or reduce the image area that needs to be retained, or adjust the position of the image area that needs to be retained. In this way, the user adjusts the image area that needs to be retained, so that the wallpaper finally set on each screen can better meet the user's expectations.

[0021] In a possible implementation of the first aspect, the subject may include a first subject and a second subject, and the folding screen device may include a first screen and a second screen, wherein the size of the first screen is smaller than the size of the second screen. According to the position of the subject in the image and the size information of each screen of the folding screen device, the image is cropped to obtain multiple wallpaper images adapted to each screen, including: respectively determining the priority of the first subject and the second subject; when the priority of the first subject is higher than the priority of the second subject, according to the position of the first subject in the image and the size information of each screen of the folding screen device, the image is cropped to obtain a first wallpaper image adapted to the first screen, and the image is cropped to obtain a second wallpaper image adapted to the second screen; wherein the first wallpaper image includes the first subject.

[0022] For example, the first screen may be an outer screen of a foldable screen device, and the second screen may be an inner screen of the foldable screen device. In the case where the image includes multiple subjects, the foldable screen device may crop the image according to the priorities of the multiple subjects, so that each cropped wallpaper image includes the first subject with the highest priority among the subjects.

[0023] In a possible implementation of the first aspect, according to the position of the first main object in the image and the size information of each screen of the folding screen device, the image is cropped to obtain a first wallpaper image adapted to the first screen, including: determining a first image area containing the first main object according to the position of the first main object in the image; and cropping the image according to the size information of the first screen to obtain a first wallpaper image containing the first image area, wherein the first wallpaper image has the same aspect ratio as the first screen.

[0024] In another possible implementation of the first aspect, the image is cropped to obtain a second wallpaper image adapted to the second screen, including: determining a second image area according to positions of the first subject and the second subject in the image, the second image area including the first subject and the second subject; and cropping the image according to size information of the second screen to obtain a second wallpaper image including the second image area, wherein the second wallpaper image has the same aspect ratio as the second screen.

[0025] In this way, when there are multiple subjects, the image can be cropped according to the priority of the subjects, so that when the screen size is small, the cropped wallpaper can be guaranteed to include the subjects with high priority. For a larger screen, more other subjects can be included on this basis, and more image features in the original image can be retained as much as possible.

[0026] In a possible implementation of the first aspect, the image is cropped according to the size information of the first screen to obtain a first wallpaper image including the first image area, including: determining the proportional deviation between the size of the first screen and the size of the first image area; if the proportional deviation is greater than a preset deviation value, determining the position of the main part of the first subject in the first image area; and the first image area is cropped according to the size information of the first screen to obtain the first wallpaper image including the main part of the first subject.

[0027] It should be understood that the above-mentioned proportional deviation can be used to characterize the degree of adaptation between the size of the first screen and the size of the first image area, and the proportional deviation can be determined by the aspect ratio of the first screen or the first image area. When the proportional deviation is small, the degree of adaptation between the size of the first screen and the size of the first image area is high; when the proportional deviation is large, the degree of adaptation between the size of the first screen and the size of the first image area is low. Exemplarily, if the proportional deviation between the first screen and the first image area is small, it means that the aspect ratio of the two is close, and the first image area is cropped according to the size of the first screen, and the cropped wallpaper image can include more features in the first image area. If the proportional deviation between the first screen and the first image area is large, it means that the aspect ratio of the two is large, and it is difficult to include all the features in the first image area in the cropped wallpaper image when the first image area is cropped according to the size of the first screen.

[0028] When the ratio of the size of the first screen to the size of the first image area deviates greatly, the folding screen device may crop the first image area to retain only the main part of the first subject. In this way, the first wallpaper image used as the first screen of smaller size may include the main features of the first subject.

[0029] In a possible implementation manner of the first aspect, the number of the first subject objects may include multiple, and according to the position of the first subject object in the image, a first image area containing the first subject object is determined, including: according to the folding method of the folding screen device, determining a first target subject object from multiple first subject objects; according to the position of the first target subject object in the image, determining an area in the image containing a target feature of the first target subject object as the first image area.

[0030] The first subject is the subject with the highest priority in the image. When there are multiple subjects with the highest priority in the image, the folding screen device can determine the first target subject from the multiple first subjects, so that when cutting wallpaper for the smaller external screen, the image can be cut to retain the area containing the first target subject in the image, ensuring that the features of the first target subject are included in the first wallpaper image as much as possible.

[0031] In a possible implementation of the first aspect, each wallpaper image is set as the wallpaper of the corresponding screen, including: previewing each wallpaper image on the corresponding screen; when receiving an interactive instruction for any previewed wallpaper image, adjusting the previewed wallpaper image according to the interactive instruction; setting each adjusted wallpaper image as the wallpaper of the corresponding screen. By previewing each cropped wallpaper image, it is convenient for the user to view the effect after the wallpaper is set, and it is convenient for the user to adjust the wallpaper according to the actual display effect, so that the wallpaper finally set meets the user's expectations and satisfies the user's needs.

[0032] In a second aspect, a wallpaper setting device for a folding screen device is provided, comprising:

The main object includes multiple parts, and different parts have different priorities, and the main part has the highest priority.

[0040] In a possible implementation manner of the second aspect, the cropping module may also be used to: determine a center point of the main object; and based on the center point, determine a region in the image that contains target features of the main object as an image region that needs to be retained.

In some embodiments of the present application, the audio module 170 can also transmit audio signals to the wireless communication module 160 via the PCM interface to realize the function of answering calls through a Bluetooth headset.

[0082] The UART interface is a universal serial data bus for asynchronous communication. The bus can be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments of the present application, the UART interface is generally used to connect the processor 110 and the wireless communication module 160. For example, the processor 110 communicates with the Bluetooth module in the wireless communication module 160 through the UART interface to implement the Bluetooth function. In some embodiments of the present application, the audio module 170 can transmit an audio signal to the wireless communication module 160 through the UART interface to implement the function of playing music through a Bluetooth headset.

[0083] The MIPI interface can be used to connect the processor 110 with peripheral devices such as the display screen 194 and the camera 193. The MIPI interface includes a camera serial interface (CSI), a display serial interface (DSI), and the like.

[0084] In some embodiments of the present application, the processor 110 and the camera 193 communicate via a CSI interface to implement the shooting function of the electronic device 100. The processor 110 and the display screen 194 communicate via a DSI interface to implement the display function of the electronic device 100.

The electronic device 100 can also calculate the position of the touch based on the detection signal of the pressure sensor 180A.

[0118] In some embodiments of the present application, touch operations acting on the same touch position but with different touch operation strengths may correspond to different operation instructions.

The gyroscope sensor 180B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the electronic device 100 shaking, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the electronic device 100 through reverse movement to achieve anti-shake. The gyroscope sensor 180B can also be used for navigation and somatosensory game scenes.

[0120] The air pressure sensor 180C is used to measure air pressure. In some embodiments of the present application, the electronic device 100 calculates the altitude, assists positioning and navigation through the air pressure value measured by the air pressure sensor 180C.

The electronic device 100 uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100.

[0127] The temperature sensor 180J is used to detect temperature. In some embodiments of the present application, the electronic device 100 uses the temperature detected by the temperature sensor 180J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 reduces the performance of the processor located near the temperature sensor 180J to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 due to low temperature. In some other embodiments, when the temperature is lower than another threshold, the electronic device 100 boosts the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

[0128] The touch sensor 180K is also called a "touch control device". The touch sensor 180K can be set on the display screen 194.

The touch vibration feedback effect can also support customization.

[0133] The indicator 192 may be an indicator light, which may be used to indicate the charging status, power changes, messages, missed calls, notifications, etc.

[0134] The SIM card interface 195 is used to connect a SIM card.

The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0135] The wallpaper setting method provided in the embodiment of the present application can be implemented on an electronic device having the above-mentioned hardware structure.

[0136] As mentioned above, the screen of a foldable screen device includes an outer screen and an inner screen. When users set wallpapers for the screen of a foldable screen device, they need to set wallpapers for the outer screen and the inner screen respectively. Due to the difference in size information between the outer screen and the inner screen, if the same image is cropped in the same way, the resulting screen wallpaper will have a large difference in effect on the outer screen and the inner screen.

[0137] In response to the above problems, an embodiment of the present application provides a wallpaper setting method for a folding screen device. By identifying the main object in the image used as the screen wallpaper, the image can be cropped using different cropping methods according to the position of the main object in the image and the size information of each screen of the folding screen device, thereby obtaining multiple wallpaper images. Each of the multiple wallpaper images can be used as the wallpaper of a screen of the folding screen device. Exemplarily, for the external screen and the internal screen of different sizes of the folding screen device, two different cropping methods can be used to crop the image. For example, cropping method one and cropping method two. Among them, the folding screen device can crop the wallpaper for the external screen according to cropping method one to obtain a wallpaper image (for example, wallpaper image one); and crop the wallpaper for the internal screen according to cropping method two to obtain another wallpaper image (for example, wallpaper image two). Then, the folding screen device can use wallpaper image one as the wallpaper of the external screen and wallpaper image two as the wallpaper of the internal screen, so as to ensure that each wallpaper image obtained by cropping can be adapted to the size of the corresponding screen.

[0138] In an embodiment of the present application, when the folding screen device crops an image according to the above-mentioned cropping method one or cropping method two, the cropping can be performed according to the position of the main object in the identified image to ensure that the cropped wallpaper includes the above-mentioned main object or a main part of the main object. When cropping, the folding screen device can determine whether to crop the image to retain the complete main object in the image or only retain a main part of the main object in the image according to the size of the screen. Usually, for a larger screen, the folding screen device can crop the image to retain the complete main object in the image; for a smaller screen, the folding screen device can only retain a main part of the main object in the image after cropping the image. Among them, the main part can be a part that reflects the main features of the main object. For example, if the main object in the identified image is a person, then the main part of the main object can be a face part.

[0139] like Figure 2 , which is a schematic diagram of a wallpaper setting effect provided by an embodiment of the present application. Figure 2 In the figure, image 201 is an image planned to be used as a screen wallpaper for a folding screen device. Image 201 includes a person, who is also the main object in image 201. Figure 2 A folding screen device 202 is also shown in FIG. 1 , and the folding screen device 202 is a vertically foldable electronic device. The outer screen of the folding screen device 202 in the folded state is as follows: Figure 2 As shown in 2021, the inner screen of the folding screen device 202 in the unfolded state is as shown in Figure 2 2022. Figure 2It can be seen that the size of the outer screen 2021 is smaller than that of the inner screen 2022. When the folding screen device 202 sets wallpaper for the above-mentioned outer screen 2021 and inner screen 2022, different cropping methods can be adopted according to the position of the main object in the image 201 and the size of the outer screen 2021 and the inner screen 2022. Specifically, since the size of the outer screen 2021 is small and cannot completely accommodate the main object in the image 201, the folding screen device 202 can retain the main part of the main object when cropping, that is, crop the image 201, retain the facial part of the person in the image 201, and obtain a wallpaper image 2021a. After the wallpaper image 2021a is set as the wallpaper of the outer screen 2021, the effect in the folded state of the folding screen device 202 can be as follows. Figure 2 On the other hand, the size of the inner screen 2022 of the folding screen device 202 in the unfolded state is relatively large, and can completely accommodate the main object in the image 201. Therefore, the folding screen device 202 can crop the image 201, retain the complete main object in the image 201, and obtain a wallpaper image 222a. After the wallpaper image 2022a is set as the wallpaper of the inner screen 2022, the effect can be as follows: Figure 2 As shown in 2022b.

[0140] Compare Figure 2 As can be seen from the screens 2021b and 2022b in the figure, by using the wallpaper setting method provided in the embodiment of the present application, the image can be cropped in a targeted manner according to the different size information of the inner and outer screens of the folding screen device, so as to obtain a wallpaper image that matches the actual size information of each screen. In this way, it can not only ensure that the wallpaper images used as the outer and inner screens contain the main object or the main part of the main object in the original image, so that the wallpaper images of the inner and outer screens will not be violently cropped due to the morphological changes of the inner and outer screens of the folding screen device, but also ensure that the style of the wallpaper images of the inner and outer screens is unified.

[0141] In a possible implementation of an embodiment of the present application, the number of main objects contained in the image used as wallpaper for each screen of a folding screen device may be more than one. Exemplarily, the image includes two or more main objects. For an image including two or more main objects, the wallpaper setting method provided in an embodiment of the present application may also be used to crop the image to obtain multiple wallpaper images that are respectively adapted to each screen.

[0142] like Figure 3 , which is a schematic diagram of another wallpaper setting effect provided by an embodiment of the present application. Figure 3 In the figure, image 301 is an image planned to be used as a screen wallpaper for a folding screen device, and image 301 includes two main objects, namely person 3011 and person 3012 in image 301. Figure 3A folding screen device 302 is also shown in FIG. 3 , and the folding screen device 302 is an electronic device that folds horizontally. The outer screen of the folding screen device 302 in the folded state is as follows: Figure 3 As shown in 3021 in FIG. 1 , the inner screen of the folding screen device 302 in the unfolded state is as shown in FIG. Figure 3 As shown in 3022. Figure 3 It can be seen that the size of the outer screen 3021 is smaller than that of the inner screen 3022. When the folding screen device 302 sets wallpaper for the above-mentioned outer screen 3021 and inner screen 3022, different cropping methods can be adopted according to the position of the main object in the image 301 and the size information of the outer screen 3021 and the inner screen 3022. Specifically, since the size of the outer screen 3021 is small and cannot completely accommodate multiple main objects in the image 301, the folding screen device 302 can crop the image 301 to obtain a wallpaper image 3021a that only contains one main object in the image 301. The wallpaper image 3021a is also the wallpaper image obtained by cropping the image 301 and retaining the person 3011 in the image 301. After the wallpaper image 3021a is set as the wallpaper of the outer screen 3021, the effect in the folded state of the folding screen device 302 can be as follows. Figure 3 On the other hand, the size of the inner screen 3022 of the folding screen device 302 in the unfolded state is relatively large, and can completely accommodate multiple main objects in the image 301. Therefore, when the folding screen device 302 is cropped, the multiple main objects in the image 301 can be retained, so that the cropped wallpaper image 3022a also includes multiple main objects in the image 301. For example, Figure 3 The wallpaper image 3022a includes the characters 3011 and 3012 in the original image 301. After the wallpaper image 3022a is set as the wallpaper of the inner screen 3022, the effect can be as follows: Figure 3 As shown in 3022b.

[0143] Compare Figure 3As can be seen from the screens 3021b and 3022b in the figure, when the image used as the screen wallpaper contains multiple main objects, the wallpaper setting method provided in the embodiment of the present application can be used to crop the image in a targeted manner according to the different sizes of the inner screen and the outer screen of the folding screen device, so that the wallpaper image used as the screen with a smaller size only contains part of the main objects in the original image, and for the screen with a larger size, the wallpaper image adapted to the screen obtained by cropping can contain all the main objects in the original image. In this way, the wallpaper images set as the inner screen and the outer screen of the folding screen device can contain different main objects, which increases the user's fun of use during the unfolding or folding process of the folding screen device. For example, when the image planned to be used as the screen wallpaper is a photo of a couple, the wallpaper image set as the outer screen with a smaller size can be a single image of one of the couple, while the wallpaper image set as the inner screen with a larger size can be a photo of the two people, thereby increasing the user's fun in the process of folding or unfolding the folding screen device.

[0144] Combination Figure 2 and Figure 3 An example of the wallpaper setting effect shown is Figure 4 As shown, a schematic diagram of the overall framework of a wallpaper setting method for a folding screen device provided in an embodiment of the present application is shown. The implementation of the method may include the following parts S401-S405:

[0145] S401. Information input.

[0146] In an embodiment of the present application, the input information may refer to relevant information that the folding screen device needs to determine before setting the wallpaper of each screen. Among them, the input information may include an image used as the screen wallpaper of the folding screen device and related information of the image. The image can be any image selected by the user from multiple images stored in the folding screen device, or it can be an image taken in real time by the user using the camera of the folding screen device, or it can be an image received by the folding screen device from other devices. Exemplarily, the folding screen device can receive images from other devices through short-range communication technologies such as Bluetooth, or through wireless communication technologies such as 4G / 5G, and use the received images as wallpaper images for each screen of the device. Figure 4 As shown, the relevant information of the image used as screen wallpaper may include the size information of the image, for example, the maximum size of the image, that is, the length and width information of the image.

[0147] In addition to the image used as screen wallpaper, the input information may also include device information of the folding screen device itself. Figure 4 As shown, the device information may include the size information of each screen of the folding screen device. For example, the size of the inner screen and the size of the outer screen of the folding screen device.

[0148] In one example, in the unfolded state, the size of the outer screen of the folding screen device is smaller than the size of the inner screen. Therefore, the outer screen of the folding screen device can also be called a small screen, and the inner screen of the folding screen device can also be called a large screen. Based on the above image and the device information of the folding screen device itself, the size information of the wallpaper used as the inner screen and outer screen of the folding screen device can also be determined, that is, the large screen wallpaper size and the small screen wallpaper size. The above large screen wallpaper size and small screen wallpaper size can also be used as input information and play a role in the subsequent wallpaper setting process.

[0149] S402: Image enhancement.

[0150] In the embodiment of the present application, for the image to be used as the screen wallpaper, the folding screen device can use image enhancement technology to process the image. Figure 4 As shown, the image enhancement technologies that can be used by foldable screen devices may include image resolution enhancement technology and image intelligent expansion technology. Based on the above image enhancement technology, foldable screen devices can use artificial intelligence or use large models and other technical means to enhance image resolution, expand image edges, and improve image clarity.

[0151] S403: Identify the main object in the image.

[0152] In the embodiment of the present application, image subject recognition may refer to the recognition of information or content contained in an image used as a screen wallpaper, and the calculation of image features. For example, through image subject recognition, the subject such as a person, animal or plant contained in the image may be identified.

[0153] In a possible implementation of the embodiment of the present application, the image may contain only a single subject. Exemplarily, the image contains only one person, or one animal, or one plant. In another possible implementation of the embodiment of the present application, the image may also contain multiple subjects. Among them, the multiple subjects may be the same subject. Exemplarily, the image may contain multiple people, or multiple animals, or multiple plants. In another possible implementation of the embodiment of the present application, the multiple subjects may be different types of subjects, and the number of each type of subject may be more than one. Exemplarily, the image may contain both people and animals. Among them, the number of people may be one or more, and the number of animals may also be one or more.

[0154] In a possible implementation of an embodiment of the present application, when an image includes multiple different types of subjects, the folding screen device may also determine the priority of each identified subject during the process of identifying the subject of the image. Compared with subjects with low priorities, subjects with high priorities can be preferentially guaranteed to exist in the cropped wallpaper images when they are cropped as wallpaper images for each screen. Exemplarily, when a folding screen device crops an image that contains both a person and an animal, if the priority of the person is higher than that of the animal, the folding screen device may preferentially crop the person in the image, and preferentially ensure that the cropped wallpaper image contains the image of the person.

[0155] As an example of an embodiment of the present application, Figure 4 As shown, the priority relationship between different types of subjects can be as follows:

[0156] People > Animals > Plants or flowers > Buildings > Starry sky, moon, sun, earth, etc. > Objects with dense textures > Two-dimensional subjects > Objects with prominent brightness or saturation > Other subjects

[0157] The symbol “>” in the above example indicates that the priority of the subject on the left side of the symbol is “higher” than the priority of the subject on the right side of the symbol. For example, in the above example, the priority of people is higher than that of animals, and the priority of animals is higher than that of plants or flowers, buildings, the starry sky, the moon, the sun, the earth and other subjects.

[0158] S404: Generate cutting model.

[0159] In an embodiment of the present application, the generation of a cropping model may refer to the process of generating different schemes for cropping images by a folding screen device, including image cropping parameter calculation and wallpaper image generation. The image cropping parameter calculation may refer to the process of calculating the parameters required to crop the wallpaper image for each screen based on the position of the identified subject in the image and the size information of each screen of the folding screen device. On this basis, the folding screen device can crop the image according to the calculated parameters by executing the wallpaper image generation step to obtain screen wallpapers that are adapted to each screen.

[0160] In the process of generating the wallpaper image, the computer device can generate different cropping solutions according to different folding modes of the folding screen device and the number of main objects in the image. Figure 4As shown, for the case where the image contains only a single subject, the folding screen device can generate a large-screen vertical folding and cutting scheme, a small-screen horizontal folding and cutting scheme, etc.; correspondingly, for the case where the image contains multiple subjects, the folding screen device can also generate a large-screen vertical folding and cutting scheme, a small-screen horizontal folding and cutting scheme, etc. Wherein, when the number of subjects is different, the actual cutting method of the same type of cutting scheme is different. Exemplarily, the large-screen vertical folding and cutting scheme for a single subject and the large-screen vertical folding and cutting scheme for multiple subjects belong to different cutting schemes. When different cutting schemes are used to crop an image, the image information contained in the cropped image is different. That is, when different cutting schemes are used to crop an image, the content or image area of ​​the original image retained in the wallpaper image after cropping is different.

[0161] Below, with specific examples, the process of generating cropping models for different numbers of main objects in the image on folding screen devices with different folding methods is introduced.

[0162] a. Vertical folding device + single main object

[0163] Among them, the vertical folding device may refer to a folding screen device whose folding method is vertical folding.

[0164] like Figure 5 FIG. 1 is a schematic diagram of a process of cutting an image provided by an embodiment of the present application. Figure 5 Shown is an example of cropping a wallpaper image for a vertically folded folding screen device when the image contains only a single subject.

[0165] exist Figure 5 In the figure, image 501 contains only a single main object, namely main object 5011, and the folding screen device 502 can identify the main object 5011 through the S403 image main object identification step. Figure 5 The folding screen device 502 is a vertical folding device, and the outer screen and inner screen of the folding screen device 502 in the folded state and the unfolded state can be respectively as follows Figure 5 As shown in the figure, screens 5021 and 5022 are shown in the figure. Screen 5021 is the outer screen of the folding screen device 502 in the folded state, and screen 5022 is the inner screen of the folding screen device 502 in the unfolded state. Figure 5 It can be seen that the size of the outer screen in the folded state is smaller than the inner screen in the unfolded state. The folding screen device 502 needs to cut out wallpaper images for screens 5021 and 5022 from the image 501 respectively.

[0166] In the embodiment of the present application, the folding screen device 502 can determine the image area in the image 501 that contains the subject 5011 according to the position of the subject 5011 in the image 501. In a possible implementation, the folding screen device can determine the center point of the subject 5011 according to the position of the subject 5011 in the image 501, and then determine the area in the image 501 that contains the target features of the subject 5011 as the image area that needs to be retained based on the center point. Figure 5 As shown, the image region to be retained may be region 501a in image 501, and region 501a includes relatively complete features of subject 5011, referred to as complete features for short.

[0167] After determining the image area to be retained, the folding screen device 502 can crop the image 501 according to the size information of each screen, and obtain multiple wallpaper images adapted to each screen. That is, the folding screen device 502 can crop the image 501 to obtain an image that can be used as the wallpaper of the screens 5021 and 5022. In an example, the folding screen device 502 can crop the image in different directions according to different folding methods when cropping the image. Exemplarily, the folding method of the folding screen device 502 is vertical folding, so when cropping the image, the folding screen device 502 can crop the wallpaper image with the same aspect ratio as the adapted screen from the image 501 in a horizontal cropping manner. Among them, the cropping scheme used by the folding screen device 502 to crop the image 501 to obtain the wallpaper of the screen 5021 may be different from the cropping scheme used by the folding screen device 502 to crop the image 501 to obtain the wallpaper of the screen 5022.

[0168] like Figure 5 As shown, since the screen 5021 is small in size and cannot completely accommodate the complete features of the subject 5011, after determining the image area that needs to be retained in the image 501, the folding screen device 502 can crop the image 501 according to the size information of the screen 5021 to retain the area where the main part of the subject 5011 in the image 501 is located. Figure 5 In the example, the subject 5011 is a person, and the corresponding subject part can be Figure 5 By cropping the facial part in image 501, wallpaper image 5011a can be obtained. Screen 5022 is large in size and can accommodate the complete features of subject 5011, so folding screen device 502 can crop image 501 horizontally according to the size information of screen 5022 to obtain wallpaper image 5011b including subject 5011. The above wallpaper images 5011a and 5011b can be used as wallpapers of screens 5021 and 5022 of folding screen device 502, respectively.

[0169] b. Vertical folding equipment + multiple main objects

[0170] like Figure 6 FIG. 1 is a schematic diagram of another process of cutting an image provided by an embodiment of the present application. Figure 6 Shown is an example of cropping a wallpaper image for a vertically folded folding screen device when the image contains multiple subjects.

[0171] exist Figure 6 In the figure, image 601 includes multiple main objects, namely main objects 6011 and 6012. Figure 6 The folding screen device 602 in the embodiment may be Figure 5 The folding screen device 502 in the embodiment of the present invention is a vertical folding device of the same type. Accordingly, the outer screen and the inner screen of the folding screen device 602 in the folded state and the unfolded state can be respectively as follows: Figure 6 As shown in the figure, screens 6021 and 6022 are shown in the figure. Screen 6021 is the outer screen of the folding screen device 602 in the folded state, and screen 6022 is the inner screen of the folding screen device 602 in the unfolded state. The size of the outer screen in the folded state is smaller than the inner screen in the unfolded state.

[0172] Since the size of screen 6021 is small and cannot fully accommodate the target features (such as complete features) of multiple main objects 6011 and 6012, when the folding screen device cuts the wallpaper image for screen 6021, it can cut the main parts of one or more of the main objects to obtain the wallpaper image of screen 6021.

[0173] In a possible implementation of the embodiment of the present application, the folding screen device 602 may crop the main body part of one of the main objects as the wallpaper image of the screen 6021. Exemplarily, the folding screen device 602 may determine which main body part of the main object to retain in the cropped image according to the priorities of the multiple main objects in the image 601. In one example, if the priorities of the multiple main objects in the image 601 are not exactly the same, the folding screen device 602 may crop the image and retain the main body part image containing the main object with the highest priority as the wallpaper image of the screen 6021.

[0174] In another possible implementation of the embodiment of the present application, the folding screen device 602 can cut the main body parts of multiple main objects as the wallpaper image of the screen 6021. Exemplarily, the folding screen device 602 can cut the image 601 according to the size of the screen 6021, and retain the main body parts of the main objects 6011 and 6012. In an example, the main objects 6011 and 6012 in the image 601 are both people, and the main body parts of the people can be face parts. The folding screen device 602 can cut the image, retain the face parts of the main objects 6011 and 6012, and obtain image 6021a as the wallpaper image of the screen 6021. In this way, the image to be set as the wallpaper of the screen 6021 can contain the face parts of the main object 6011 and the face parts of the main object 6012 at the same time.

[0175] In a possible implementation of an embodiment of the present application, when the folding screen device 602 crops the image of the main object with the highest priority as the wallpaper image of the screen 6021, it can also perform the cropping in two situations according to the size of the screen 6021.

[0176] Case 1: assuming that the subject with the highest priority in image 601 is subject 6011, if the deviation between the aspect ratio of screen 6021 and the aspect ratio of the image area where subject 6011 is located is small, screen 6021 can accommodate the complete features of subject 6011, or the image area where subject 6011 is located is scaled so that screen 6021 can accommodate the complete features of subject 6011, then the folding screen device 602 can crop image 601 to obtain a wallpaper image containing the complete features of subject 6011, as the image to be set as the wallpaper of screen 6021.

[0177] Case 2: Assuming that the subject with the highest priority in image 601 is subject 6011, if the aspect ratio of screen 6021 deviates greatly from the aspect ratio of the image area where subject 6011 is located, screen 6021 cannot accommodate the complete features of subject 6011, or even if the image area where subject 6011 is located is scaled, screen 6021 cannot accommodate the complete features of subject 6011, then folding screen device 602 can crop image 601 to obtain a wallpaper image containing only the main part of subject 6011. For example, if subject 6011 is a person, folding screen device 602 can crop the image to obtain an image containing the facial part of the person as the image to be set as the wallpaper of screen 6021.

[0178] For screen 6022 , due to its large size, the folding screen device 602 can cut out an image 6022a that includes complete features of multiple main objects from image 601 as the wallpaper image of screen 6022 .

[0179] c. Horizontally foldable device + single main object

[0180] Among them, the horizontal folding device may refer to a folding screen device that folds vertically. Figure 7 FIG. 1 is a schematic diagram of another image cropping process provided by an embodiment of the present application. Figure 7 Shown is an example of cropping a wallpaper image for a horizontally folded folding screen device when the image contains only a single subject.

[0181] Figure 7 The image 701 in FIG. 7 only includes a single main object, namely, main object 7011. The folding screen device 702 is a horizontal folding device. The outer screen and the inner screen of the folding screen device 702 in the folded state and the unfolded state can be respectively as follows: Figure 7 As shown in the screens 7021 and 7022 in FIG. Among them, screen 7021 is the outer screen of the folding screen device 702 in the folded state, and screen 7022 is the inner screen of the folding screen device 702 in the unfolded state. Figure 7 It can be seen that the size of the outer screen in the folded state is smaller than the inner screen in the unfolded state. The folding screen device 702 needs to cut out wallpaper images for screens 7021 and 7022 from the image 701 respectively.

[0182] In the embodiment of the present application, the folding screen device 702 can determine the image area containing the main object 7011 in the image 701 according to the position of the main object 7011 in the image 701. Figure 7 As shown, the image region containing the subject 7011 may be region 701a in image 701 , and region 701a includes complete features of the subject 7011 .

[0183] For a horizontally foldable device, when cutting a wallpaper image for each screen, a wallpaper image having the same aspect ratio as the adapted screen may be cut from image 701 in a vertical cutting manner.

[0184] In a possible implementation of the embodiment of the present application, the folding screen device 702 can crop the image 701 in a vertical cropping manner according to the size information of the screen 7021 to obtain the image 7021a to be set as the wallpaper of the screen 7021; on the other hand, the folding screen device can crop the image 701 according to the size information of the screen 7022 to obtain the image 7022a to be set as the wallpaper of the screen 7022. The above-mentioned image 7021a and image 7022a can be set as the wallpaper of the screen 7021 and the screen 7022, respectively.

[0185] d. Horizontally foldable device + multiple main objects

[0186] like Figure 8 FIG. 1 is a schematic diagram of another process of cutting an image provided by an embodiment of the present application. Figure 8 Shown is an example of cropping a wallpaper image for a horizontally folded folding screen device when the image contains multiple subjects.

[0187] exist Figure 8 In the figure, image 801 includes multiple main objects, namely main objects 8011 and 8012. Figure 8 The folding screen device 802 in the embodiment may be Figure 7 The folding screen device 702 is a horizontal folding device of the same type. Accordingly, the outer screen and the inner screen of the folding screen device 802 in the folded state and the unfolded state can be respectively as follows: Figure 8 As shown in the figure, screens 8021 and 8022 are shown in the figure. Screen 8021 is the outer screen of the folding screen device 802 in the folded state, and screen 8022 is the inner screen of the folding screen device 802 in the unfolded state. The size of the outer screen in the folded state is smaller than the inner screen in the unfolded state.

[0188] In a possible implementation of an embodiment of the present application, when the folding screen device 802 cuts the wallpaper image for each screen, it can cut out multiple wallpaper images from the image 801, and the number of main objects contained in each wallpaper image can be different.

[0189] Exemplarily, when the folding screen device 802 crops a wallpaper image for the screen 8021 , an image containing only a single subject object may be cropped from the image 801 .

[0190] In an embodiment of the present application, when the folding screen device 802 crops a single subject, it can determine which subject to crop and retain based on the priorities of multiple subjects in the image 801. In one example, if the priorities of multiple subjects in the image 801 are not exactly the same, the folding screen device 802 can crop the image and retain the image containing the subject with the highest priority as the wallpaper image of the screen 8021. In another example, if the priorities of multiple subjects in the image 801 are the same, for example, subjects 8011 and 8012 in the image 801 are both human images and have the same priority, the folding screen device 802 can randomly crop the image in a vertical cropping manner and retain the image containing any one of the subjects as the wallpaper image of the screen 8021. For example, Figure 8 As shown, the folding screen device can crop image 801 to obtain image 8021a containing the main object 8011 as the wallpaper image of screen 8021.

[0191] On the other hand, when the folding screen device 802 cuts the wallpaper image for the screen 8022, it can cut out an image containing multiple subjects from the image 801. Figure 8 As shown, the folding screen device can crop image 801 in a vertical cropping manner to obtain image 8022a containing main objects 8011 and 8012 as the wallpaper image of screen 8022.

[0192] S405. Interface interaction.

[0193] In an embodiment of the present application, the interface interaction function may refer to a function in which the folding screen device allows the user to adjust each wallpaper image after cropping the wallpaper images of each screen and previewing the wallpaper images on the adapted screens. The interface interaction function provided by the folding screen device may include one-click settings of folded and unfolded wallpapers and previews of folded and unfolded wallpapers. The folded state refers to the device state presented by at least one foldable screen of the folding screen device, such as the inner screen of the folding screen device, after being folded; the unfolded state refers to the device state presented when the inner screen of the folding screen device is not folded, that is, when it is unfolded.

[0194] In a possible implementation of an embodiment of the present application, a folding screen device may provide a one-key setting button. When the user clicks the button, the folding screen device may automatically present the cropped wallpaper images on a screen that matches the wallpaper image, and intelligently adjust the wallpaper image to ensure that the main object or the main part of the main object in the image can be fully presented on the screen. On this basis, the user can continue to adjust the wallpaper image presented on the screen. For example, the user can adjust the wallpaper image by dragging, zooming, and other operations. After the user has finished adjusting the wallpaper image, the folding screen device can set the adjusted image as the wallpaper of the corresponding screen.

[0195] like Fig. 9 , which is a schematic diagram of interface interaction in a wallpaper setting method provided in an embodiment of the present application. Fig. 9 The folding screen device 901 in the embodiment may be a horizontal folding device, and the outer screen of the folding screen device 901 in the folded state may be as shown in FIG. Fig. 9 As shown in screen 9011. Fig. 9 9 shows an example in which the folding screen device 901 cuts out a corresponding wallpaper image for the screen 9011 and previews the wallpaper image on the screen 9011. During the interface interaction process, the folding screen device 901 can display an edit button 903 on the screen 9011, and the user can enter the editing state by clicking the button 903.

[0196] In the editing state, users can adjust the wallpaper image. Fig. 9As shown, the user's adjustment of the wallpaper image may include operations such as moving the image position, scaling the image, or deleting the main object in the image.

[0197] Combination Figures 4 to 9 The wallpaper setting process shown in Fig.10 As shown, a schematic diagram of a method for setting wallpaper for a folding screen device provided in an embodiment of the present application is shown. Fig.10 According to the process shown, the folding screen device can set the screen wallpaper of the inner screen and the outer screen in four different situations according to the number of main objects in the image and the folding method of the folding screen device. The following is a detailed description.

[0198] according to Fig.10 According to the process shown, the user can select an image as the image to be set as the screen wallpaper. For this image, the folding screen device can perform image enhancement processing on it, improve the image resolution, and expand the resolution of the image edge. Then, the folding screen device can identify the main object in the image. The methods used by the folding screen device to identify the main object may include but are not limited to artificial intelligence large models, texture feature analysis, etc. If there is no clear main object in the image, the folding screen device can cut out the corresponding wallpaper image for the inner screen and the outer screen respectively by cutting in the middle. If there is a clear main object in the image, the folding screen device can identify the characteristics of the main object, and further determine the type and quantity of the main object, the position of each main object in the image and other information.

[0199] like Fig.10 As shown, for the case where the image contains only a single main object, the folding screen device can use different cropping models to crop the image according to its own folding method. In one example, if the folding screen device is a horizontal folding device, the folding screen device can crop the image in a vertical cropping manner; if the folding screen device is a vertical folding device, the folding screen device can crop the image in a horizontal cropping manner. The process of the folding screen device cropping the image to obtain a wallpaper image adapted to each screen can be found in the introduction of the aforementioned embodiments, and will not be repeated here.

[0200] Based on the cropped wallpaper images, the foldable screen device can preview the inner and outer screen wallpapers through interface interaction. After the user completes the adjustment of the wallpaper image, the foldable screen device can complete the wallpaper setting for the inner and outer screens with one click under the user's operation.

[0201] like Fig.11 , which is a comparative schematic diagram of a wallpaper setting effect provided in an embodiment of the present application. Fig.11Shown are examples of cropping images for a horizontally folding device and a vertically folding device and setting them as inner and outer screen wallpapers when the image contains only a single main object, as well as a comparison diagram of setting inner and outer screen wallpapers for a horizontally folding device and a vertically folding device in the prior art.

[0202] like Fig.11 As shown in (a) of the figure, a single subject in an image is cropped using the method provided in an embodiment of the present application to obtain an external screen wallpaper image and an internal screen wallpaper image of a horizontally foldable device and complete the wallpaper setting, and an external screen wallpaper image and an internal screen wallpaper image of a vertically foldable device are obtained and complete the wallpaper setting. The external screen and the internal screen of the horizontally foldable device can be as follows Fig.11 As shown in the screen 1111a and the screen 1112a in (a), the outer screen and the inner screen of the vertical folding device can be as shown in FIG. Fig.11 As shown in the screen 1121a and the screen 1122a in (a), when the image 1101 is cropped according to the method provided in the embodiment of the present application, the main object in the image 1101 can be firstly identified, and then the image 1101 can be cropped according to the position of the main object in the image and the size information of each screen to obtain the corresponding wallpaper image. Fig.11 As can be seen in (a), whether it is a horizontally folding device or a vertically folding device, in the folded state and the unfolded state, the outer screen wallpaper image and the inner screen wallpaper image both contain the complete main object in the original image 1101. Fig.11 (b) shows an example of using a cropping method in the prior art to crop an image to obtain an inner screen wallpaper image and an outer screen wallpaper image of a horizontally foldable device, and an example of obtaining an inner screen wallpaper image and an outer screen wallpaper image of a vertically foldable device. The outer screen and inner screen of the horizontally foldable device can be as follows Fig.11 As shown in the screen 1111b and the screen 1112b in (b), the outer screen and the inner screen of the vertical folding device can be as shown in FIG. Fig.11 As shown in screen 1121b and screen 1122b in (b), the above-mentioned screen 1111a and screen 1111b are the same screen, screen 1112a and screen 1112b are the same screen, screen 1121a and screen 1121b are the same screen, and screen 1122a and screen 1122b are the same screen. When image 1101 is cropped according to the prior art, for screen 1111b, the folding screen device crops along the middle of image 1101, that is, area 1101b in image 1101 is cropped to obtain the corresponding wallpaper image. For screen 1121b, the folding screen device also crops along the middle of image 1101, that is, area 1101a in image 1101 is cropped to obtain the corresponding wallpaper image. From Fig.11As can be seen in (b), for the same image, the inner screen wallpaper image in the unfolded state contains the complete main object in the original image, but because the folding screen device in the prior art uses the middle cropping method to crop the image, the main object in the original image is cropped from the middle, and the resulting outer screen wallpaper image of the horizontal folding device in the folded state destroys the integrity of the main object, seriously affecting the setting effect of the outer screen wallpaper. On the other hand, for the vertical folding device, when the same image is cropped, the main objects in both the outer screen wallpaper image of the vertical folding device in the folded state and the inner screen wallpaper image in the unfolded state are destroyed.

[0203] like Fig.12 , which is a comparative schematic diagram of another wallpaper setting effect provided in an embodiment of the present application. Fig.12 Shown are examples of cropping images for a horizontally folding device and a vertically folding device and setting them as inner and outer screen wallpapers when the image contains multiple subjects, as well as a comparison diagram of setting inner and outer screen wallpapers for a horizontally folding device and a vertically folding device in the prior art.

[0204] like Fig.12 As shown in (a), it shows an example of the effect after the image is set by cropping multiple main objects in the image using the method provided in the embodiment of the present application to obtain the outer screen wallpaper image and inner screen wallpaper image of the horizontal folding device and the vertical folding screen device respectively. Among them, the outer screen and inner screen of the horizontal folding device are respectively Fig.12 The screen 1211a and the screen 1212a in (a); the outer screen and the inner screen of the vertical folding device are respectively Fig.12 Screen 1221a and screen 1222a in (a). Fig.12 The image 1201 used in (a) in FIG. 1 includes two subjects, namely subject 1 and subject 2. Subject 1 and subject 2 are arranged side by side horizontally in the image 1201. Fig.12 As can be seen in (a), after the image 1201 is cropped according to the method provided in the embodiment of the present application, and the cropped wallpaper image is set as the wallpaper of the corresponding screen, in the folded state, the outer screen wallpaper image of the horizontally folded device includes the complete image of the subject 1 in the original image; in the unfolded state, the inner screen wallpaper image includes the complete images of the subject 1 and the subject 2 in the original image. On the other hand, in the folded state, the outer screen wallpaper image of the vertically folded device includes the image of the main body of the subject 1 and the subject 2 in the original image, that is, the face part of the subject 1 and the subject 2 in the image 1201; in the unfolded state, the inner screen wallpaper image includes the complete images of the subject 1 and the subject 2 in the original image. Fig.12(b) shows an example of an inner screen wallpaper image and an outer screen wallpaper image of a horizontally folding device obtained by cropping the image using the cropping method in the prior art, as well as an example of an inner screen wallpaper image and an outer screen wallpaper image of a vertically folding device.

[0205] Among them, the outer screen and inner screen of the horizontally folding device can be as follows Fig.12 As shown in the screen 1211b and the screen 1212b in (b), the outer screen and the inner screen of the vertical folding device can be as shown in FIG. Fig.12 As shown in screen 1221b and screen 1222b in (b), the above-mentioned screen 1211a and screen 1211b are the same screen, screen 1212a and screen 1212b are the same screen, screen 1221a and screen 1221b are the same screen, and screen 1222a and screen 1222b are the same screen. When image 1201 is cropped according to the prior art, for screen 1211b, the folding screen device crops along the middle of image 1201, that is, area 1201b in image 1201 is cropped to obtain a corresponding wallpaper image. For screen 1221b, the folding screen device crops along the middle of image 1201 according to the size information of screen 1221b, that is, area 1201a in image 1201 is cropped to obtain a corresponding wallpaper image. From Fig.12 As can be seen in (b), for Fig.12 For the same image 1201 shown in (a), after the wallpaper is cut and set for a horizontally folding device, the inner screen wallpaper image in the unfolded state includes the complete images of the subject 1 and the subject 2 in the original image 1201. However, since the folding screen device in the prior art cuts the image in the middle, when cutting the wallpaper image for the outer screen, the subject 1 and the subject 2 that are arranged side by side horizontally in the original image 1201 are cut from the middle of the image. The resulting outer screen wallpaper image in the folded state only includes a part of the image of the subject 1 and the subject 2. The outer screen wallpaper image destroys the integrity of the subject 1 and the subject 2 in the original image, seriously affecting the setting effect of the outer screen wallpaper. On the other hand, for vertically folding devices, for Fig.12 In the same image 1201 shown in (a) of FIG. 1 , the inner screen wallpaper image in the unfolded state of the vertical folding device and the outer screen wallpaper image in the folded state both only contain partial images of the subject 1 and the subject 2 in the original image. The above images are obtained by cropping the original image in the middle cropping manner. Fig.12 As can be seen in (b), the outer screen wallpaper image and the inner screen wallpaper image obtained by cutting according to the prior art both destroy the integrity of the main object 1 and the main object 2 in the original image.

[0206] Based on the above embodiments, Fig.13, which is a schematic diagram of a wallpaper setting method for a folding screen device provided in an embodiment of the present application, and the method may include the following steps S1301-S1303:

[0207] S1301, identifying the main object in the image.

[0208] The method can be applied to a folding screen device, which can be a device having a Figure 1 An electronic device with the hardware structure shown in FIG. A folding screen device may include multiple screens, at least one of which is foldable. Exemplarily, the folding screen device may include an inner screen and an outer screen, wherein the inner screen may be foldable. Depending on the folding direction, the folding screen device may be divided into a horizontal folding device and a vertical folding device. A vertical folding device may be as follows: Figure 2 As shown in the folding screen device 202 in FIG. 1 , the outer screen of the vertical folding device in the folded state can be as shown in FIG. Figure 2 As shown in the outer screen 21 in the figure, the inner screen in the unfolded state can be as follows Figure 2 As shown in the inner screen 2022 in FIG. A horizontally foldable device can be as follows Figure 3 As shown in the folding screen device 302 in FIG. 1 , the outer screen of the horizontal folding device in the folded state can be as follows Figure 3 As shown in the outer screen 3021 in FIG. 1 , the inner screen in the unfolded state can be as follows Figure 3 As shown in the inner screen 3022.

[0209] The image in the embodiment of the present application may be an image used as wallpaper for each screen of the folding screen device, and the folding screen device may obtain the wallpaper image for each screen by cropping the image. The image may be an image determined from the images stored in the folding screen device, or an image taken by the user in real time using the folding screen device, or an image received from other devices through various communication technologies.

[0210] Before setting the wallpaper of each screen, the folding screen device can identify the main object from the image. Among them, the number of main objects in the image can be only one or multiple. When the number of main objects in the image is multiple, the multiple main objects can be the same type of main objects or different types of main objects. Exemplarily, the image includes two main objects, both of which are people; or, one of the two main objects is a person, and the other is an animal or a plant. Multiple main objects can have corresponding priorities respectively. When the types of main objects in the image are the same, the priorities of multiple main objects can be the same; when the image includes multiple different types of main objects, the priorities between different types of main objects can be different.

[0211] S1302. Crop the image to obtain multiple wallpaper images adapted to the respective screens according to the position of the subject in the image and the size information of the respective screens of the folding screen device; wherein the sizes of the respective screens are different, and the subject is included in any wallpaper image.

[0212] After identifying the main object in the image, the folding screen device can crop the image according to the position of the main object in the image, ensuring that each wallpaper image obtained by cropping includes the main object in the image. In one example, the cropped wallpaper image including the main object can refer to including target features of the main object, such as the complete features of the main object itself, or the complete features of the main part of the main object.

[0213] When a folding screen device crops the main object in an image, it can also crop according to the size information of each of its own screens, so that the size of each cropped wallpaper image can be adapted to one screen, that is, each cropped wallpaper image has the same aspect ratio as the adapted screen.

[0214] In a possible implementation of the embodiment of the present application, the folding screen device can determine the image containing the subject according to the position of the subject in the image. Specifically, the folding screen device can determine the center point of the subject according to the position of the subject in the image, and then determine the area in the image containing the complete features of the subject as the image area to be retained based on the determined center point. For example, Figure 5 As shown, the area where the main object 5011 in the image 501 is located is area 501a, and the area 501a can be used as the image area that needs to be retained when the folding screen device cuts the image 501.

[0215] Then, the folding screen device can crop the image according to the size information of each screen to obtain multiple wallpaper images adapted to each screen. Figure 5 By cropping image 501, wallpaper images 5011a and 5011b can be obtained, wherein wallpaper image 5011a is a wallpaper image adapted to screen 5021 of folding screen device 502, and wallpaper image 5011b is a wallpaper image adapted to screen 5022.

[0216] Generally, different types of folding screen devices have different folding methods. For example, some folding screen devices fold horizontally, while other folding screen devices fold vertically. Different folding methods may correspond to different cutting directions. Among them, the cutting direction corresponding to the horizontal folding may be vertical cutting, and the cutting direction corresponding to the vertical folding may be horizontal cutting.

[0217] Therefore, when cropping an image, the folding screen device can first determine its own folding method, and crop the image according to the cropping direction corresponding to the folding method to obtain multiple wallpaper images. Specifically, if the folding method of the folding screen device is horizontal, a wallpaper image with the same aspect ratio as the compatible screen can be cropped from the image in a vertical cropping manner; if the folding method of the folding screen device is vertical, a wallpaper image with the same aspect ratio as the compatible screen can be cropped from the image in a horizontal cropping manner.

[0218] In a possible implementation of an embodiment of the present application, the screen of a folding screen device includes a first screen and a second screen. For example, the first screen may be the outer screen of the folding screen device, and the second screen may be the inner screen of the folding screen device. The size of the first screen is usually smaller than that of the second screen. When cropping a wallpaper image for the first screen, it may be impossible to completely crop out the complete features of the subject due to the relatively small size of the first screen. Therefore, the folding screen device can determine the position of the main part of the subject in the image area, and then crop the image according to the size information of the first screen to obtain a first wallpaper image that includes the main part of the subject and is compatible with the first screen. Generally, the subject may include multiple parts, different subjects include different parts, and the priorities of different parts may also be different. When cropping the image to retain the main part of the subject, the main part may be the part with the highest priority. Exemplarily, if the subject is a person, then the face part may be the main part of the subject. For example, in Figure 5 In the figure, the main object 5011 is a person, and the corresponding main object part is the face of the person. The folding screen device image can be cropped to obtain a wallpaper image 5011a, which is an image that retains the face of the main object 5011.

[0219] In another possible implementation of the embodiment of the present application, the number of main objects in the image may also include multiple ones. For example, the image includes a first main object and a second main object, and the folding screen device may include a first screen and a second screen, and the size of the first screen is smaller than the size of the second screen. When cropping wallpaper images for each screen of the folding screen device, the folding screen device may respectively determine the priority of the first main object and the second main object. If the priority of the first main object is higher than the priority of the second main object, the folding screen device may crop the image to obtain a first wallpaper image adapted to the first screen and crop the image to obtain a second wallpaper image adapted to the second screen based on the position of the first main object in the image and the size information of each screen of the folding screen device. When cropping according to such a cropping scheme, the cropped first wallpaper image may include the first main object with the highest priority among multiple main objects. Exemplarily, in combination Figure 4The priorities of different subjects shown in , if the image contains both human and plant subjects, since the priority of human is higher than that of plant, when cutting the wallpaper image for the first screen, the first wallpaper image obtained should include the image of human. In one example, if the size of the first screen is small, the folding screen device cannot completely cut out the images of multiple subjects when cutting the image according to the size information of the first screen, for example, it cannot cut out the image containing both human and plant from the image according to the size information of the first screen, the folding screen device can only cut out the subject with the highest priority, the human, to obtain the first wallpaper image containing human. If the folding screen device can completely cut out the image containing multiple subjects when cutting the image according to the size information of the first screen, for example, it can cut out the image containing both human and plant from the image, the folding screen device can cut the human and plant to obtain the first wallpaper image containing human and plant. In this way, no matter which method is used for cutting, the first wallpaper image obtained can contain the first subject with the highest priority.

[0220] In the specific implementation process, the folding screen device can determine the first image area containing the first main object according to the position of the first main object in the image, and then crop the image according to the size information of the first screen to obtain a first wallpaper image containing the first image area, so that the cropped first wallpaper image has the same aspect ratio as the first screen.

[0221] In another possible implementation, the folding screen device can determine the proportional deviation between the size of the first screen and the size of the first image area. The proportional deviation can be used to indicate whether the size of the first screen matches the size of the first image area. If the proportional deviation is greater than the preset deviation value, it means that if the image is cropped according to the size of the first screen, the complete features of the first subject may not be included in the cropped first wallpaper image. At this time, the folding screen device can determine the position of the main part of the first subject in the first image area, and crop the first image area according to the size information of the first screen to obtain a first wallpaper image containing the main part of the first subject. That is, the folding screen device crops the first image area, and only retains the main features of the subject in the cropped first wallpaper image.

[0222] In another possible implementation of the embodiment of the present application, the number of first subjects may also include multiple subjects, that is, the number of subjects with the highest priority in the image includes multiple subjects. Exemplarily, the image contains multiple character images. At this time, the folding screen device can determine the first target subject from multiple first subjects according to the folding method; then, according to the position of the first target subject in the image, the area in the image containing the target feature of the first target subject is determined as the first image area to be retained. The above-mentioned area containing the target feature may be the area where the image that embodies the main features of the first target subject is located. The folding screen device cuts the image to obtain a first wallpaper image containing the above-mentioned target feature and adapted to the first screen. In an example, the folding method of the folding screen device is horizontal folding, and the folding screen device is adjusted from the folded state to the unfolded state from right to left. If multiple first subjects in the image are arranged side by side, the folding screen device can determine the first subject arranged side by side on the right as the first target subject. In this way, the cut first wallpaper image can only contain the subject arranged side by side on the right or the target feature of the subject, and the second wallpaper image can contain multiple subjects at the same time. When a user uses a folding screen device, during the process of adjusting the folding screen device from a folded state to an unfolded state, the main object in the wallpaper can be presented with an effect of changing from a single main object in the outer screen wallpaper to multiple main objects in the inner screen wallpaper, thereby enhancing the user experience.

[0223] For the second screen, the folding screen device can determine the second image area according to the positions of the first main object and the second main object in the image, so that the second image area includes the first main object and the second main object. Then, the folding screen device can crop the image according to the size information of the second screen to obtain a second wallpaper image including the second image area. The second wallpaper image has the same aspect ratio as the second screen.

[0224] S1303: Set each wallpaper image as the wallpaper of the corresponding screen.

[0225] After cropping the wallpaper images that are adapted to each screen, the folding screen device can set each wallpaper image as the wallpaper of the adapted screen. Figure 5 The wallpaper image 5011a is set as the wallpaper of the corresponding screen 5021, and the wallpaper image 5011b is set as the wallpaper of the corresponding screen 5022.

[0226] In a possible implementation of an embodiment of the present application, after the folding screen device cuts out the wallpaper images for each screen, it can also preview each wallpaper image on the corresponding screen, so that the user can view the effect of the wallpaper setting and adjust the wallpaper image. The user's adjustment of the wallpaper image can be achieved through interactive instructions on each screen. When the folding screen device receives an interactive instruction for any previewed wallpaper image, the previewed wallpaper image can be adjusted according to the interactive instruction. These adjustments may include moving the position of the wallpaper image, scaling the size, deleting characters in the wallpaper image, and so on. After the adjustment is completed, the folding screen device can set the adjusted wallpaper images as the wallpaper of the corresponding screen, and complete the setting of wallpapers for multiple screens with one click.

[0227] The embodiment of the present application can obtain multiple wallpaper images by identifying the main object in the image, and then cropping the image according to the position of the main object in the image and the size information of each screen of the folding screen device. Since each wallpaper image is obtained by cropping the main object in the image according to the size information of a certain screen, it can not only ensure that the cropped wallpaper image contains the main object in the original image, but also make the size information of each wallpaper image match the size information of the corresponding screen. The embodiment of the present application can solve the problem in the prior art that it is easy to destroy the integrity of the main object in the image by cropping along the middle of the image for screens of any size information, reduce the possibility of large differences in the final effects of the wallpaper image on the inner and outer screens, and improve the aesthetics and uniformity of the screen wallpaper of the folding screen device.
