Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a cover display method and a terminal device. Background Art

[0002] With the development of electronic technology and terminal products, the usage rate of multimedia files such as pictures and videos in users' daily lives is increasing. Generally, a large number of multimedia files such as pictures and videos may be stored in terminal devices such as mobile phones, tablets, and personal computers (PCs).

[0003] The terminal device can divide a large number of pictures stored in the gallery into one or more albums according to the geographical location information and shooting time information of the photos. In the prior art, the terminal device usually uses a clearer picture in the album, or the first picture or the last picture in the album as the album cover. Among them, for one of the albums, the first picture of the album can be understood as the picture in the album whose shooting time (or the time saved to the local gallery) is farthest from the current time, and the last picture can be understood as the picture whose shooting time is closest to the current time.

[0004] However, the cover display effect generated by the above method is single, which may be difficult to highlight the content that the user expects to express through the cover, and the user experience is not high. Summary of the invention

[0005] The present application provides a cover display method and terminal device, which are conducive to increasing the hierarchy of the cover display, highlighting the content that the user hopes to express through the cover, and thus improving the user experience.

[0006] In a first aspect, a cover display method is provided, which is applied to a terminal device, and the method includes: at a first moment, displaying a first interface, the first interface including a first cover card image of a first album and label information of the first album, the first cover card image is determined based on the first cover image of the first album, the first cover card image includes a portrait in the first cover image, in the first interface, the portrait is located below the label information of the first album and does not block the label information of the first album, and the first cover image satisfies preset conditions, the preset conditions include: the number of portraits in the image is single, the face of the portrait in the image is located in a preset area of ​​the image, and the area ratio in the image is within a preset range; at a second moment, displaying a second interface, the second interface including a second cover card image of the first album and label information of the first album, the size of the first cover card image is the same as the size of the second cover card image, the second cover card image is obtained by cropping the first cover card image after enlarging it by a preset multiple, in the second interface, the portrait is located below the label information and blocks a preset part of the label information, and the second moment is later than the first moment.

[0007] The cover display method provided by the present application is applied to a terminal device. The terminal device displays the first cover card image and the label information of the first album at the first moment, and the portrait in the first cover card image does not block the label information of the first album; and displays the second cover card image and the label information of the first album at the second moment. The second cover card image is obtained by scaling up the first cover card image by a preset multiple and then cropping it. The portrait in the second pair of cover card images blocks the preset area of ​​the label information of the first album. In this way, the terminal device can dynamically display the cover of the first album, and after the dynamic change, the portrait in the second cover card image blocks the preset area of ​​the label information of the first album, visually highlighting the portrait display effect of the second cover card image, which is conducive to increasing the hierarchy of the cover display, facilitating highlighting the content that the user expects to express through the cover, and thus improving the user experience.

[0008] It should be understood that the first album includes multiple images, and the first album may be a photo collection including multiple photos, or may be a video (also referred to as a video album) generated by a terminal device based on multiple photos taken by a user. The first album may also be a video taken locally by a user or downloaded from a web page by a user, and the multiple images in the first album are multiple frames of images of the video. This application does not limit this.

[0009] It is also understood that the above-mentioned preset part can be set by the R&D personnel. Optionally, the preset part can be 1 / 2 of the height of the label information box. For example, the preset part of the label information of the first album can be the lower half of the label information of the first album, that is, the portrait blocks the lower half of the label information of the first album. Optionally, the preset part can be 1 / 2 of the height of the title box in the label information, for example, the portrait blocks the lower half of the title box.

[0010] Optionally, the preset range may be greater than or equal to the first preset threshold and less than or equal to the second preset threshold. For example, the preset range may be a closed interval [2%, 4%], that is, the face area accounts for greater than or equal to 2% and less than or equal to 4%.

[0011] Optionally, the face of the portrait in the image is located in the preset area of ​​the image can be: the ratio of the overlapping area of ​​the face frame and the preset area to the area of ​​the face frame is greater than or equal to a preset threshold. The preset threshold can be set by the R&D personnel. For example, the preset threshold can be 80%.

[0012] It should also be understood that the above-mentioned preset area can be set in a variety of ways.

[0013] In a possible implementation manner, the preset area may be an area of ​​a central grid after the image is divided into nine grids.

[0014] It should be understood that the nine-grid division means that the image is divided into nine equal parts by arranging two horizontal grid lines and two vertical grid lines in a "well" shape. The center grid of the nine-grid is a rectangular area formed by the four intersections of the two horizontal grid lines and the two vertical grid lines.

[0015] In another possible implementation, the preset area may be a fixed area of ​​the image. Optionally, the preset area may be: a horizontal grid line is drawn at 1 / 6 and 2 / 3 from top to bottom of the image in the vertical direction, a vertical grid line is drawn at 1 / 6 and 5 / 6 from left to right of the image in the horizontal direction, and a rectangular area is formed by four intersection points where two horizontal grid lines and two vertical grid lines intersect.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the above method also includes: at a third moment, displaying a third interface, the third interface including a third cover card image of the second album and label information of the second album, the third cover card image is determined based on the second cover image of the second album, and the second cover image does not meet the preset conditions.

[0017] It should be understood that the second album is similar to the first album, and will not be described in detail herein. The second cover image may be, for example, a landscape image, a multi-person image, or a person's back image.

[0018] By judging by preset conditions, the photo albums in the terminal device can be divided into two types: photo albums that meet the preset conditions and photo albums that do not meet the preset conditions. Different types of photo albums can be displayed in different cover styles, which is conducive to improving the diversity of album cover display.

[0019] In combination with the first aspect, in certain implementations of the first aspect, displaying the third interface includes: displaying the third interface in response to a user's sliding operation or a click operation on an album navigation icon, where the album navigation icon is used for the user to open an album list.

[0020] It should be understood that the album list includes at least one album. The album list includes the second album.

[0021] The following discusses the process of the terminal device displaying the third interface based on the user's operation in different situations.

[0022] Case 1: the terminal device currently displays an interface including an album navigation icon. After the user clicks the album navigation icon, the terminal device opens the album list and displays the cover of the second album (ie, the third interface).

[0023] Furthermore, the album list also includes the first album. The user slides the album from the second album to the first album by sliding in the album list, and the terminal device displays the cover of the first album. The cover display of the first album is dynamic, and the dynamic display process is: first display the first cover card image, then change from the first cover card image to the second cover card image, and finally display the second cover card image all the time.

[0024] Case 2: The user slides from other albums to the second album. The other album may be the first album, or an album other than the first album and the second album. In response to the user's sliding operation, the terminal device displays the cover of the second album (i.e., the third interface). The cover display of the second album is static.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the above method also includes: based on the aesthetic scores of multiple second images in the second album and preset conditions, determining whether there is at least one second target image in the second album, and at least one second target image meets the preset conditions; if there is no at least one second target image in the second album, determining the second cover image from the multiple second images.

[0026] It should be understood that the terminal device can score the multiple second images based on the aesthetic scoring rules to obtain the aesthetic scores of the multiple second images. This application does not limit the scoring rules for the aesthetic scoring.

[0027] By screening the covers through aesthetic scoring, some blurry or poorly composed images can be filtered out, which is helpful to improve the quality of the screened cover images.

[0028] In combination with the first aspect, in certain implementations of the first aspect, determining whether there is at least one second target image in the second album includes: selecting an image with the highest aesthetic score among multiple second images as at least one second candidate image; determining whether there is at least one second target image that meets preset conditions among the at least one second candidate image; if there is no at least one second target image in the at least one second candidate image, determining that there is no at least one second target image in the second album; determining a second cover image from the multiple second images includes: determining the second cover image from the at least one second candidate image.

[0029] In combination with the first aspect, in certain implementations of the first aspect, the number of at least one candidate image is multiple; determining the second cover image from at least one second candidate image includes: determining the image with the earliest time information in at least one second candidate image as the second cover image.

[0030] In combination with the first aspect, in certain implementations of the first aspect, displaying the first interface includes: displaying the first interface in response to a user's sliding operation or a click operation on an album navigation icon, where the album navigation icon is used for the user to open an album list.

[0031] It should be understood that the album list includes at least one album. The album list includes the first album.

[0032] Specifically, when the terminal device currently displays an interface including an album navigation icon and the album list only includes the first album, after the user clicks the album navigation icon, the terminal device opens the album list and displays the cover of the first album. When the album list includes at least two albums and the terminal device currently displays the covers of other albums, based on the user's sliding operation, the terminal device displays the cover of the first album. The cover display of the first album is dynamically displayed, and the dynamic display process is: first display the first cover card image, then change from the first cover card image to the second cover card image, and finally display the second cover card image all the time.

[0033] In combination with the first aspect, in certain implementations of the first aspect, the above method also includes: based on the aesthetic scores of multiple first images in the first album and preset conditions, judging whether there is at least one first target image in the first album, and at least one first target image meets the preset conditions; when there is at least one first target image in the first album, determining the first cover image from the at least one first target image.

[0034] By screening the covers through aesthetic scoring, some blurry or poorly composed images can be filtered out, which is helpful to improve the quality of the screened cover images. Screening the covers through preset conditions is helpful to avoid the situation where the cover card images obtained by subsequent cropping based on the cover images do not meet the requirements.

[0035] In combination with the first aspect, in certain implementations of the first aspect, determining whether there is at least one first target image in the first album includes: selecting an image with the highest aesthetic score among multiple first images as at least one first candidate image; determining whether there is at least one first target image that meets preset conditions in at least one first candidate image; if there is at least one first target image in at least one first candidate image, determining that there is at least one first target image in the first album.

[0036] In combination with the first aspect, in certain implementations of the first aspect, there are multiple first target images; determining the first cover image from the at least one first target image includes: determining the image with the earliest time information in the at least one first target image as the first cover image.

[0037] In combination with the first aspect, in certain implementations of the first aspect, the above method also includes: cropping the first cover image based on the position of the portrait in the first cover image in the first cover card image and the size of the first cover card image to obtain the first cover card image.

[0038] Optionally, the first cover card image may be rectangular, and the size of the first cover card image may include a horizontal length and a vertical height of the first cover card.

[0039] In combination with the first aspect, in certain implementations of the first aspect, the eyes of the portrait in the first cover image are located at a preset position in the horizontal direction of the first cover card image, and the face frame of the portrait in the first cover image is located at a preset position in the vertical direction of the first cover card image.

[0040] It should be understood that the preset position of the first cover card image in the horizontal direction and the preset position of the first cover card image in the vertical direction can be preset by the R&D personnel. For example, the preset position of the first cover card image in the horizontal direction can be on the center line of the first cover card image in the horizontal direction. The preset position of the first cover card image in the vertical direction can be at 1 / 4 of the height from top to bottom of the first cover card image in the vertical direction.

[0041] By positioning the eyes of the portrait at preset positions in the horizontal direction and the vertical direction of the first cover card image, the portrait display area in the first cover card is determined, which helps to improve the aesthetics of the cover card image.

[0042] In combination with the first aspect, in certain implementations of the first aspect, the above method also includes: proportionally enlarging the first cover card image by a preset multiple with the face in the first cover card image as the center; taking the center of the first cover card image as the center of the second cover card image, and cropping the enlarged first cover card image to the same size as the first cover card image to obtain the second cover card image.

[0043] It should be understood that equal-proportional magnification refers to magnifying the first cover image as a whole at the same ratio, rather than magnifying a partial image in the first cover image. Optionally, the preset magnification may be 1.2 times.

[0044] Specifically, there are many implementation methods for proportionally enlarging the first cover card image by a preset multiple with the face in the first cover card image as the center, and this application does not limit this.

[0045] In a possible implementation, the first cover card image is proportionally enlarged by a preset multiple with the key point of the nose of the face in the first cover card image as the center, and the area that exceeds the size of the first cover card image after enlargement is cropped to obtain the second cover card image. The key point of the nose of the face in the first cover card image, the key point of the nose of the face in the enlarged first cover card image, and the key point of the nose of the face in the second cover card image overlap.

[0046] In another possible implementation, the first cover card image is proportionally enlarged by a preset multiple with the midpoint of the face frame (the circumscribed frame of the face outline) in the first cover card image as the center, and the area that exceeds the size of the first cover card image after enlargement is cropped to obtain the second cover card image. The midpoint of the face frame (the circumscribed frame of the face outline) in the first cover card image, the midpoint of the face frame (the circumscribed frame of the face outline) in the enlarged first cover card image, and the midpoint of the face frame (the circumscribed frame of the face outline) in the second cover card image coincide with each other.

[0047] In combination with the first aspect, in some implementations of the first aspect, the tag information includes title information and time information.

[0048] It should be understood that the title information of the first album (which can also be understood as the album name of the first album) can be automatically generated by the terminal device based on the video content, or can be created by the user, and this application does not limit this. The time information of the first album is the creation time or the last modification time of the first album.

[0049] In combination with the first aspect, in certain implementations of the first aspect, the label information is displayed in the center in the first interface or the second interface.

[0050] In combination with the first aspect, in certain implementations of the first aspect, in the first interface or the second interface, the time information is located above the title information.

[0051] In a second aspect, a terminal device is provided, which is used to execute the method in any possible implementation of the first aspect. Specifically, the terminal device includes a module for executing the method in any possible implementation of the first aspect.

[0052] In one design, the terminal device may include a module that executes the methods / operations / steps / actions described in the first aspect above, and the module may be a hardware circuit, software, or a combination of hardware circuit and software.

[0053] In a third aspect, a terminal device is provided, comprising: a processor and a memory, wherein the processor is used to read instructions stored in the memory to execute the method in any possible implementation of the first aspect.

[0054] Optionally, there are one or more processors and one or more memories.

[0071] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0072] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference.

[0073] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0074] In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0075] In the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that the device will make corresponding processing under certain objective circumstances. It does not limit the time, nor does it require the device to have a judgment action when implementing it, nor does it mean that there are other limitations.

[0076] In order to better understand the terminal device in the embodiment of the present application, Figure 1 The hardware structure of the terminal device in the embodiment of the present application is described in detail.

[0077] Figure 1 This is a schematic diagram of the structure of the terminal device 100 provided in the embodiment of the present application.

In other embodiments of the present application, the terminal device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0079] The processor 110 may include one or more processing units, for example, the processor 110 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0080] The controller can generate operation control signals according to the instruction operation code and timing signal to complete the control of instruction fetching and execution.

[0081] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0082] In some embodiments, the processor 110 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0083] The I2C interface is a bidirectional synchronous serial bus, including a serial data line (SDA) and a serial clock line (SCL). In some embodiments, the processor 110 may include multiple groups of I2C buses. The processor 110 may be coupled to the touch sensor 180K, the charger, the flash, the camera 193, etc. through different I2C bus interfaces. For example: the processor 110 may be coupled to the touch sensor 180K through the I2C interface, so that the processor 110 communicates with the touch sensor 180K through the I2C bus interface, thereby realizing the touch function of the terminal device 100.

[0084] The I2S interface can be used for audio communication. In some embodiments, the processor 110 can include multiple I2S buses. The processor 110 can be coupled to the audio module 170 via the I2S bus to achieve communication between the processor 110 and the audio module 170. In some embodiments, the audio module 170 can transmit an audio signal to the wireless communication module 160 via the I2S interface to achieve the function of answering a call through a Bluetooth headset.

[0085] The PCM interface can also be used for audio communication, sampling, quantizing and encoding analog signals. In some embodiments, the audio module 170 and the wireless communication module 160 can be coupled via a PCM bus interface. In some embodiments, 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 via a Bluetooth headset. Both the I2S interface and the PCM interface can be used for audio communication.

[0086] 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, 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, 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.

[0087] 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), etc. In some embodiments, the processor 110 and the camera 193 communicate via the CSI interface to implement the shooting function of the terminal device 100. The processor 110 and the display screen 194 communicate via the DSI interface to implement the display function of the terminal device 100.

[0088] The GPIO interface can be configured by software. The GPIO interface can be configured as a control signal or as a data signal. In some embodiments, the GPIO interface can be used to connect the processor 110 with the camera 193, the display 194, the wireless communication module 160, the audio module 170, the sensor module 180, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, a MIPI interface, etc.

[0089] The USB interface 130 is an interface that complies with the USB standard specification, and specifically can be a Mini USB interface, a Micro USB interface, a USB Type C interface, etc. The USB interface 130 can be used to connect a charger to charge the terminal device 100, and can also be used to transmit data between the terminal device 100 and peripheral devices. It can also be used to connect headphones to play audio through the headphones. The interface can also be used to connect other terminal devices, such as AR devices, etc.

[0090] It is understandable that the interface connection relationship between the modules illustrated in the embodiment of the present application is only a schematic illustration and does not constitute a structural limitation on the terminal device 100. In other embodiments of the present application, the terminal device 100 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

[0091] The charging management module 140 is used to receive charging input from a charger. The charger may be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 may receive charging input from a wired charger through the USB interface 130. In some wireless charging embodiments, the charging management module 140 may receive wireless charging input through a wireless charging coil of the terminal device 100. While the charging management module 140 is charging the battery 142, it may also power the terminal device through the power management module 141.

[0092] The power management module 141 is used to connect the battery 142, the charging management module 140 and the processor 110. The power management module 141 receives input from the battery 142 and / or the charging management module 140, and supplies power to the processor 110, the internal memory 121, the display screen 194, the camera 193, and the wireless communication module 160.

[0168] It should be understood that the preset portion can be set by the R&D personnel. Optionally, the preset portion can be 1 / 2 of the height of the label information box. For example, the preset portion of the label information of the first album can be the lower half of the label information of the first album, that is, the portrait blocks the lower half of the label information of the first album. Optionally, the preset portion can be 1 / 2 of the height of the title box in the label information, for example, the portrait blocks the lower half of the title box.

[0169] The cover display method provided by the present application is that the terminal device displays the first cover card image and the label information of the first album at the first moment, and the portrait in the first cover card image does not block the label information of the first album; and displays the second cover card image and the label information of the first album at the second moment, and the second cover card image is obtained by cropping the first cover card image after proportionally enlarging it by a preset multiple, and the portrait in the second pair of cover card images blocks the preset area of ​​the label information of the first album. In this way, the terminal device can dynamically display the cover of the first album, and after the dynamic change, the portrait in the second cover card image blocks the preset area of ​​the label information of the first album, visually highlighting the portrait display effect of the second cover card, which is conducive to increasing the hierarchy of the cover display, facilitating the highlighting of the content that the user expects to express through the cover, and thus improving the user experience.

[0170] Optionally, the terminal device can obtain the second cover card image through the following method: proportionally enlarging the first cover card image by a preset multiple with the face in the first cover card image as the center; taking the center of the first cover card image as the center of the second cover card, and cropping the enlarged first cover card image to the same size as the first cover card image to obtain the second cover card image.

[0171] It should be understood that equal-proportional magnification refers to magnifying the first cover image as a whole at the same ratio, rather than magnifying a partial image in the first cover image. Optionally, the preset magnification may be 1.2 times.

[0172] Specifically, there are many ways to implement proportionally enlarging the first cover card image by a preset multiple with the face in the first cover card image as the center, and this application does not limit this.

[0173] In a possible implementation, the terminal device may obtain the second cover card image by the following method: taking the nose key point of the face in the first cover card image as the center, proportionally enlarging the first cover card image by a preset multiple, and then cropping the area beyond the first cover card image after enlargement to obtain the second cover card image. The nose key point of the face in the first cover card image, the nose key point of the face in the enlarged first cover card image, and the nose key point of the face in the second cover card image overlap.

[0174] In another possible implementation, the terminal device may obtain the second cover card image by the following method: taking the midpoint of the face frame (the circumscribed frame of the face outline) in the first cover card image as the center, proportionally enlarging the first cover card image by a preset multiple, and then cropping the area that exceeds the first cover card image after enlargement to obtain the second cover card image. The midpoint of the face frame (the circumscribed frame of the face outline) in the first cover card image, the midpoint of the face frame (the circumscribed frame of the face outline) in the enlarged first cover card image, and the midpoint of the face frame (the circumscribed frame of the face outline) in the second cover card image coincide with each other.

[0175] For example, Figure 4 A schematic diagram of a method for obtaining a second cover card image based on a first cover card image is shown. Figure 4 a is the first cover card image, the large rectangle can be the frame of the first cover card image, the small rectangle can be the face frame in the first cover card image, and the solid circle is the center of the face frame. The first cover card image is enlarged with the solid circle as the center to obtain the enlarged first cover card image. The enlarged first cover card image is as shown in Figure 4 As shown in b, the dotted rectangle is the frame of the enlarged first cover card image, the dotted rectangle is the face frame of the enlarged face of the first cover card image, the solid circle is the center of the face frame, and the solid rectangle is the frame of the first cover card image. The solid circle in the first cover card image (i.e., the center of the face frame) is overlapped with the solid circle in the enlarged first cover card image (i.e., the center of the face frame). The enlarged first cover card image is cropped based on the frame of the first cover card image, and the cropped area is as shown in the shaded area to obtain Figure 4 The c shown is the second cover card image.

[0176] Optionally, in the first interface or the second interface, the label information is displayed in the center.

[0177] As an optional embodiment, displaying the first interface includes: displaying the first interface in response to a sliding operation of the user or a click operation of an album navigation icon, where the album navigation icon is used for the user to open an album list.

[0178] It should be understood that the album list includes at least one album. The album list includes the first album.

[0179] Specifically, when the terminal device currently displays an interface including an album navigation icon and the album list only includes the first album, after the user clicks the album navigation icon, the terminal device opens the album list and displays the cover of the first album. When the album list includes at least two albums and the terminal device currently displays the covers of other albums, based on the user's sliding operation, the terminal device displays the cover of the first album. The cover display of the first album is dynamically displayed, and the dynamic display process is: first display the first cover card image, then change from the first cover card image to the second cover card image, and finally display the second cover card image all the time.

[0180] As an optional embodiment, the above method also includes: at a third moment, displaying a third interface, the third interface including a third cover card image of the second album and label information of the second album, the third cover card image is determined based on the second cover image of the second album, and the second cover image does not meet the preset conditions.

[0181] It should be understood that the second album is similar to the first album, and will not be described in detail herein. The second cover image may be, for example, a landscape image, a multi-person image, or a person's back image.

[0182] By judging by preset conditions, the photo albums in the terminal device can be divided into two types: photo albums that meet the preset conditions and photo albums that do not meet the preset conditions. Different types of photo albums can be displayed in different cover styles, which is conducive to improving the diversity of album cover display.

[0183] Optionally, the label information of the second album includes title information and time information of the second album. The time information and title information can be distributed up and down, or left and right, and this application does not limit this. The label information of the second album can be located in a non-face area on the third cover card image, or the label information of the second album can be located in an area with a preset number of color types in the third cover card image. The display color of the label information of the second album can be intelligently selected according to the background of the image. For example, the display color of the label information can be selected in a color that is consistent with the background color tone of the image. The text of the label information of the second album can be an artistic font.

[0184] Optionally, the preset number can be set by the R&D personnel. For example, when the preset number is set to 1, the terminal device can display the label information of the second album in the solid color area of ​​the third cover card image.

[0185] Optionally, the terminal device may crop (also referred to as recomposition) the second cover image based on major elements in the second cover image by one or more of the symmetry rule, diagonal rule, center rule, and rule of thirds to obtain a third cover card image.

[0186] Exemplarily, when the main element in the cover image is a portrait, the terminal device can, based on the rule of thirds, crop the second cover image by displaying the person in the second cover image in the lower 2 / 3 area of ​​the third cover card image to obtain the third cover card image. When the main element in the third cover image is a bilaterally symmetrical building, the terminal device can, based on the rule of symmetry, crop the third cover image by displaying the building in the center of the third cover card image to obtain the third cover card image. When the main element in the second cover image is a stream, the terminal device can, based on the rule of diagonals, crop the second cover image by displaying the stream in the third cover image on the diagonal of the third cover card image to obtain the third cover card image.

[0187] Optionally, the terminal device displays a third interface in response to a user's sliding operation or a click operation on an album navigation icon, where the album navigation icon is used for the user to open an album list.

[0188] It should be understood that the album list includes at least one album. The album list includes the second album.

[0189] The following discusses the process of the terminal device displaying the third interface based on the user's operation in different situations.

[0190] Case 1: the terminal device currently displays an interface including an album navigation icon. After the user clicks the album navigation icon, the terminal device opens the album list and displays the cover of the second album (ie, the third interface).

[0191] Furthermore, the album list also includes the first album. The user slides the album from the second album to the first album by sliding in the album list, and the terminal device displays the cover of the first album. The cover display of the first album is dynamic, and the dynamic display process is: first display the first cover card image, then change from the first cover card image to the second cover card image, and finally display the second cover card image all the time.

[0192] Case 2: The user slides from other albums to the second album. The other album may be the first album, or an album other than the first album and the second album. In response to the user's sliding operation, the terminal device displays the cover of the second album (i.e., the third interface). The cover display of the second album is static.

[0193] Taking a mobile phone as an example, the following describes in detail the interface display change process in the cover display method provided in this application.

[0194] Figure 5 The following is a diagram showing the interface changes of a mobile phone's album cover display. Figure 5 In the interface a shown in the figure, the "Camera", "Contacts", "Phone", and "Message" application icons are displayed at the bottom of the interface, and the "Clock", "Calendar", "Gallery", and "Memo" application icons are displayed in the middle of the interface. After the user clicks the "Gallery" application icon, the mobile phone responds to the user's click operation, opens the gallery, and displays Figure 5 Interface b shown. Figure 5 In the interface b shown, the images in the gallery are displayed in chronological order. The interface includes all images saved "today" and some images saved "yesterday". The size of each image is the same, and three images are displayed in a row. The navigation icons of "Photos", "Albums", "Memories", and "Creations" and the corresponding navigation names are displayed at the bottom of the interface. Among them, the gallery content corresponding to the "Memories" navigation item is the album generated by the mobile phone after classifying the photos in the gallery. After the user clicks the icon of the "Memories" navigation item, the mobile phone responds to the user's click operation and the interface first displays Figure 5 The interface c shown in the figure then smoothly transitions from interface c to Figure 5 In the interface d shown, the smooth transition is a dynamic change process, and the dynamic effect is: the portrait and background in interface c gradually become larger, and after freezing, they appear as the portrait and background in interface d. Figure 5 In the interface c shown, the title "Memories" is displayed at the top of the interface, and a search box is displayed below the title. A rounded rectangular cover card (which can also be understood as the above-mentioned cover card image) is displayed below the search box. A front-facing portrait is displayed in the center of the cover card, and the title information "Time is like a dream" is displayed in the center above the portrait. The time information "July 12, 2022" is displayed above the title information, and the portrait does not block the title information. Figure 5 In the interface d shown, the "Memories" interface title bar is displayed at the top of the interface, and a search box is displayed below the interface title bar. A rounded rectangular cover card is displayed below the search box, with a portrait in the center of the cover card, and the title information "Time is like a dream" is displayed in the center above the portrait. The time information "July 12, 2022" is displayed above the title information, and the portrait covers 1 / 2 of the title information.

[0195] Optionally, in Figure 5 In the interface d shown, after the user swipes up on the cover card, the mobile phone responds to the user's swipe up operation and displays Figure 5 The interface shown is e. Figure 5 In the interface e shown, the "Memories" interface title bar is displayed at the top of the interface, and a search box is displayed below the interface title bar. A rounded rectangular cover card is displayed below the search box, and a side-sitting portrait of a person looking at a mobile phone is displayed in the center of the cover card. The title information "Fleeting Years" is displayed at the bottom of the portrait, and the time information "July 12, 2022" is displayed above the title information. The title information and time information are displayed in the upper layer at the bottom of the portrait.

[0196] Optionally, the user Figure 5 After clicking the icon of the "Memories" navigation item in the interface b shown, the mobile phone responds to the user's click operation and displays Figure 5 The interface shown is e.

[0197] Optionally, Figure 5 The original image of the album cover in the interface e shown does not meet the preset conditions. Figure 5 In the interface b shown, the user clicks the "Discover" icon (i.e., the album navigation icon), and the phone displays Figure 5 The interface e shown (that is, the third interface mentioned above) is shown. Figure 5 In the interface d shown, the user swipes up and the phone displays Figure 5 The interface shown is e.

[0198] Optionally, Figure 5 The original image of the album cover in the interface c shown meets the preset conditions. Figure 5 In the interface b shown, the user clicks the "Discover" icon (i.e., the album navigation icon), and the phone displays Figure 5 The interface c (i.e. the first interface) shown in the figure is then smoothly transitioned from the interface c to the display Figure 5 The interface d (i.e., the second interface) is shown. Figure 5 In the interface e shown, the user swipes up and the phone displays Figure 5 The interface c (i.e. the first interface) shown in the figure is then smoothly transitioned from the interface c to the display Figure 5 The interface d (ie the second interface) is shown.

[0199] As an optional embodiment, the above method also includes: based on the aesthetic scores of multiple second images in the second album and preset conditions, judging whether there is at least one second target image in the second album, and the at least one second target image satisfies the preset conditions; if the at least one second target image does not exist in the second album, determining the second cover image from the multiple second images.

[0200] It should be understood that the terminal device can score the multiple second images based on the aesthetic scoring rules to obtain the aesthetic scores of the multiple second images. This application does not limit the scoring rules for the aesthetic scoring.

[0201] Optionally, the terminal device selects the image with the highest aesthetic score among multiple second images as at least one second candidate image; determines whether there is at least one second target image that meets the above-mentioned preset conditions among the at least one second candidate image; if the at least one second target image does not exist among the at least one second candidate image, determines that the at least one second target image does not exist in the second album; and the terminal device determines a second cover image from the at least one second candidate image.

[0202] By screening the covers through aesthetic scoring, some blurry or poorly composed images can be filtered out, which is helpful to improve the quality of the screened cover images. Screening the covers through preset conditions is helpful to avoid the situation where the cover card images obtained by subsequent cropping based on the cover images do not meet the requirements.

[0203] Optionally, there are multiple at least one candidate image, and the image with the earliest time information among the at least one second candidate image is determined as the second cover image.

[0204] As an optional embodiment, the above method also includes: based on the aesthetic scores of multiple first images in the first album and preset conditions, judging whether there is at least one first target image in the first album, and the at least one first target image satisfies the above preset conditions; if the at least one first target image exists in the first album, determining the first cover image from the at least one first target image.

[0205] Optionally, an image with the highest aesthetic score among multiple first images is selected as at least one first candidate image; it is determined whether there is at least one first target image that meets the above-mentioned preset conditions in the at least one first candidate image; if there is at least one first target image in the at least one first candidate image, it is determined that the at least one first target image exists in the first album.

[0206] Optionally, there are multiple at least one first target image, and the image with the earliest time information among the at least one first target image is determined as the first cover image.

[0207] As an optional embodiment, the method further includes: cropping the first cover image based on the position of the portrait in the first cover image in the first cover card image and the size of the first cover card image to obtain the first cover card image.

[0208] Optionally, the eyes of the portrait in the first cover image are located at a preset position in the horizontal direction of the first cover card image, and the face frame of the portrait in the first cover image is located at a preset position in the vertical direction of the first cover card image.

[0209] It should be understood that the preset position of the first cover card image in the horizontal direction and the preset position of the first cover card image in the vertical direction can be preset by the R&D personnel. For example, the preset position of the first cover card image in the horizontal direction can be on the center line of the first cover card image in the horizontal direction. The preset position of the first cover card image in the vertical direction can be at 1 / 4 of the height from top to bottom of the first cover card image in the vertical direction.

[0210] By positioning the eyes of the portrait at preset positions in the horizontal direction and the vertical direction of the first cover card image, the portrait display area in the first cover card is determined, which helps to improve the aesthetics of the cover card image.

[0211] Next, from the perspective of internal judgment, combined with Figure 6 The cover display method of an embodiment of the present application is introduced in detail.

[0212] Figure 6 600 is a schematic flow chart of a cover display method 600 provided in an embodiment of the present application. The hardware structure of the terminal device involved in the method 600 can be as follows: Figure 1 As shown, the software structure can be as follows Figure 2 shown.

[0213] S601: The terminal device obtains multiple original images.

[0214] Specifically, the multiple original images may be multiple frames of images in a video stored on the terminal device. The video may be generated by the terminal device based on multiple photos taken by the user. It may also be a video taken locally by the user or downloaded from a web page by the user. The multiple original images may also be multiple images in an album on the terminal device.

[0215] S602: The terminal device performs aesthetic scoring on the multiple original images according to a preset aesthetic scoring rule.

[0216] S603: The terminal device selects an original image with the highest aesthetic score from multiple original images as a candidate image.

[0217] It should be understood that determining candidate images according to aesthetic scores may include a variety of situations.

[0218] Case 1: The number of images with the highest score is one, so the number of candidate images is one.

[0219] Case 2: There are multiple images with the highest scores, so there are multiple candidate images.

[0220] For example, there are 20 original images in the video, and the terminal device performs aesthetic scoring on the 20 original images. The aesthetic scores of landscape image A, single person image B, single person image C, and single person image D are all the highest score of 90 points, so the terminal device determines that landscape image A, single person image B, single person image C, and single person image D are all candidate images, and the number of candidate images is 4. When the aesthetic score of landscape image A is the highest score of 90 points, and the aesthetic scores of single person image B, single person image C, and single person image D are 89 points, the terminal device determines that landscape image A is a candidate image, and the number of candidate images is 1.

[0221] S604: The terminal device determines whether the number of candidate images is one.

[0222] When the number of candidate images is one, after S604 , the terminal device executes S605 ; when the number of candidate images is multiple, after S604 , the terminal device executes S613 .

[0223] S605: The terminal device uses the candidate image as the cover image.

[0224] S606: The terminal device determines whether the cover image is an image of a single person.

[0225] Specifically, the terminal device detects the number of portraits in the cover image, and if the number of portraits is one, it is determined that the cover image is a single-person image.

[0226] When the cover image is a single-person image, after S606 , the terminal device executes S607 ; when the cover image is not a single-person image, after S606 , the terminal device executes S611 .

[0227] S607, the terminal device performs face detection on the cover image, obtains the face position, and calculates the face area ratio of the cover image.

[0228] Specifically, the terminal device performs face detection on the cover image to obtain a face frame, which is an external frame of the face outline. The face position can be represented by the coordinates of a point at a preset position on the face frame, and the face area can be the area of ​​the face frame. The face area ratio is the area ratio of the face in the cover image in the cover image.

[0229] Optionally, the face frame may be a circle, the face position may be represented by a circle point and coordinates of four points evenly distributed on the circumference, and the face area may be the area of ​​the circle.

[0230] Optionally, the face frame may be a rectangle, the face position may be represented by the coordinates of four vertices of the rectangle, and the face area may be the area of ​​the rectangle.

[0231] S608, the terminal device determines whether the cover image meets a preset condition, which is that the face position is within a preset area and the face area ratio is within a preset range.

[0232] Optionally, the face position in the preset area may be: the ratio of the overlapping area of ​​the face frame and the preset area to the area of ​​the face frame is greater than or equal to a preset threshold, for example, the preset threshold may be 80%.

[0233] Optionally, the preset range can be greater than or equal to the first preset threshold and less than or equal to the second preset threshold. For example, the preset range can be a closed interval [2%, 4%], that is, the face area accounts for greater than or equal to 2% and less than or equal to 4%.

[0234] It should be understood that the above-mentioned preset area can be set in a variety of ways.

[0235] In a possible implementation, the preset area may be the area of ​​the center grid after the image is divided into a nine-grid grid. It should be understood that the nine-grid grid division means: the image is divided into nine equal parts by arranging two horizontal grid lines and two vertical grid lines in a "well" shape. The center grid of the nine-grid grid is a rectangular area formed by the four intersections of the two horizontal grid lines and the two vertical grid lines.

[0236] Figure 7 It is a schematic diagram of the positional relationship between a face and a preset area. Figure 7 As shown, the image is divided into nine-square grids, the shadow area is the preset area, and the overlapping area between the face frame and the preset area (ie, the shadow area) is greater than 80%, and it is determined that the face position is in the preset area.

[0237] In another possible implementation, the preset area may be a fixed area of ​​the image. Optionally, the preset area may be: a horizontal grid line is drawn at 1 / 6 and 2 / 3 from top to bottom of the image in the vertical direction, a vertical grid line is drawn at 1 / 6 and 5 / 6 from left to right of the image in the horizontal direction, and a rectangular area is formed by four intersection points where two horizontal grid lines and two vertical grid lines intersect.

[0238] Figure 8 is a schematic diagram of the positional relationship between another face and the preset area. Figure 8 As shown in FIG. 1 , after the cover image is divided based on two horizontal grid lines (horizontal dotted lines) and two vertical grid lines (vertical dotted lines), the shaded area is the preset area. Figure 8As shown, the overlapping area between the face frame and the preset area (ie, the shadow area) is 100%, which is greater than the preset threshold of 80%, and it is determined that the face position is in the preset area.

[0239] When the cover image meets the preset condition, after S608, the terminal device executes S609; when the cover image does not meet the preset condition, after S608, the terminal device executes S611.

[0240] S609: The terminal device determines the cover card based on the size of the cover card and the display position of the person in the cover image in the cover card.

[0241] It should be understood that the cover card is an image of the entire or partial area of ​​the cover image.

[0242] Optionally, the terminal device obtains the size of the cover card, detects the character in the cover image, crops the cover image based on the display position of the character in the cover card and the size of the cover card, and determines the cover card.

[0243] Optionally, the cover card may be rectangular, and the size of the cover card includes the horizontal length and vertical height of the cover card.

[0244] S610: The terminal device displays the cover card in a first preset style.

[0245] Specifically, the terminal device displays the cover card in the first preset style, which can be a dynamic display effect of smoothly transitioning from the first interface to the second interface in the above method 400. Exemplarily, the display style of the first preset style can be: Figure 5 The interface c shown transitions smoothly to Figure 5 The interface d shown in the figure is finally frozen. Figure 5 The dynamically changing style of interface d is shown.

[0246] S611: The terminal device determines the cover card based on the size of the cover card and the display positions of the main elements in the cover image in the cover card.

[0247] Optionally, the terminal device may determine the cover card by cropping the cover image based on the display position of the main elements in the cover card and the size of the cover card using one or more of the symmetry rule, the diagonal rule, the center rule, and the rule of thirds.

[0248] It should be understood that in this step, the main element in the cover image may be a single person, multiple people, or scenery in the image that does not meet the preset conditions.

[0249] Exemplarily, when the main element in the cover image is a single person portrait, the terminal device can crop the cover image based on the rule of thirds by displaying the person in the cover image in the lower 2 / 3 area of ​​the cover card to obtain a cover card. When the main element in the cover image is a bilaterally symmetrical building, the terminal device can crop the cover image based on the rule of symmetry by displaying the building in the center of the cover card to obtain a cover card. When the main element in the cover image is a stream, the terminal device can crop the cover image based on the rule of diagonals by displaying the stream in the cover image on the diagonal line of the cover card to obtain a cover card.

[0250] S612: The terminal device displays the cover card in a second preset style.

[0251] Specifically, the second preset style is a static style. The cover card is displayed on the terminal device. The non-face area of ​​the cover card displays label information. The label information includes time information and title information. The title information is above the time information.

[0252] Optionally, the font of the label information is an artistic font, and the color of the label information can be automatically selected according to the background color of the image.

[0253] Optionally, the label information is displayed in a location of the cover card where the image has less color. For example, the label information is displayed in a solid color area of ​​the cover card.

[0254] It should be understood that the terminal device may display the cover card in the second preset style as the display effect of the third interface described above. Figure 5 The interface shown is e.

[0255] S613: The terminal device traverses and detects whether the multiple candidate images include a single person image.

[0256] When there is a single person image among the multiple candidate images, S614 is executed after S613 ; when there is no single person image among the multiple candidate images, S616 is executed after S613 .

[0257] S614, the terminal device performs face detection on each single person image, obtains the face position, and calculates the face area ratio of each single person image.

[0258] S615, the terminal device detects whether each single person image meets the above preset conditions, and determines whether the number of images meeting the preset conditions is 0, 1, or more.

[0259] When the number of images satisfying the preset condition is 0, after S615, the terminal device executes S616; when the number of images satisfying the preset condition is 1, after S615, the terminal device executes S609; when the number of images satisfying the preset condition is multiple, after S615, the terminal device executes S617.

[0260] S616: The terminal device obtains time information of the multiple candidate images, and selects the candidate image with the earliest time as the cover image.

[0261] It should be understood that each image includes time information. When the image is a local image, the time information of the image may be the moment when the terminal device takes the image; when the image is an image downloaded by the terminal device from a web page, the time of the image may be the moment when the terminal device downloads the image. This application does not impose any restrictions on this.

[0262] S617, the terminal device obtains time information of the multiple single-person images, and selects the single-person image with the earliest time as the cover image.

[0263] It should be understood that the order of execution of each process in the above method 600 does not mean the order of execution. The execution order of each process should be determined by its function and internal logic.

[0264] In the above S609, the terminal device crops the cover image and determines the cover card through the following multiple implementation methods. Fig. 9 It is a schematic diagram of determining a cover card provided in an embodiment of the present application.

[0265] In a first possible implementation, the terminal device identifies a face frame in the cover image, obtains the position of the face frame and the size of the cover card, and crops the cover image based on the size of the cover card in a manner such that the face frame is displayed at a preset height in the vertical direction of the cover card and is centered in the horizontal direction of the cover card to obtain a cover card.

[0266] For example, Fig. 9 As shown in a, the largest dotted rectangle is the cover image, the larger solid rectangle is the cover card, the smallest solid rectangle is the face frame, and the horizontal dotted line on the cover card is a horizontal auxiliary line of a preset height, which is 1 / 4 of the height of the cover card from top to bottom in the vertical direction. The vertical dotted line on the cover card is the centerline auxiliary line of the cover card in the horizontal direction. The terminal device crops the cover image based on the size of the cover card in such a way that the upper edge of the face frame is close to the horizontal auxiliary line of the preset height, and the centerline of the face frame in the horizontal direction coincides with the horizontal centerline auxiliary line of the cover card to obtain a cover card.

The horizontal dotted line on the cover card is a horizontal auxiliary line of a preset height, and the preset height is 1 / 4 of the height of the cover card from top to bottom. The cover card includes two left and right vertical grid lines. The terminal device crops the cover image based on the size of the cover card in such a manner that the upper edge of the face frame is close to the horizontal auxiliary line of the preset height of the cover card, and the eye position is displayed on the right vertical grid line, or the upper edge of the face frame is close to the horizontal auxiliary line of the preset height, and the eye position is displayed on the left vertical grid line to obtain a cover card.

[0275] It should be understood that when the portrait's posture is such that the horizontal midline of the portrait's body frame is on the left of the horizontal midline of the portrait's face frame, the above-mentioned eye position is displayed on the right vertical grid line; when the portrait's posture is such that the horizontal midline of the portrait's body frame is on the right of the horizontal midline of the portrait's face frame, the above-mentioned eye position is displayed on the left vertical grid line.

[0276] It should be understood that the preset height of the cover card in the vertical direction may be set by R&D personnel.
