Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

With the improvement of the hardware performance of the mobile terminal, more mobile terminals can support the display of higher-definition pictures in the user interface of the application program. However, the inventor found in the research that the factors affecting the display effect of the picture are not only the information of the picture itself, but also the degree of matching between the picture information and the user interface of the application program.

Take the color gamut space as an example. Color gamut, or color gamut space, is a method of encoding a color, and also refers to the sum of colors that a technical system can produce. In computer graphics, a color gamut is some complete subset of colors. The color gamut space can include sRGB color gamut, Adobe RGB color gamut or DCI-P3 color gamut. Among them, sRGB is one of the earliest color gamut standards, and has been supported by W3C, Exif, Intel, Pantone, Corel and many other industry manufacturers from the industry. The Adobe RGB color gamut is mainly to improve the display on the cyan color system, so it can cover about 50% of the CIE 1931XYZ color space. DCI-P3 is a color gamut used in digital cinema. It is a color gamut standard dominated by human visual experience, which matches as much as possible the full color gamut that can be displayed in movie scenes. It is also not the widest color gamut standard (currently the latest standard is BT.2020), but it has a wider red/green color range on top of the Rec.709 standard.

However, the inventor found that when a picture is displayed in the user interface of an application (for example, a user views a picture sent by the other party in a chat application), when the color gamut of the picture is inconsistent with the color gamut of the user interface of the application, the Displaying pictures with inconsistent color gamut spaces on the user interface will cause the display effect of the area where the image is located on the display area to be inconsistent with the display effect of the area where the user interface is located, thereby affecting the display effect. For example, when the corresponding picture with wider color gamut space is displayed on the corresponding user interface with narrower color gamut space, the user will see that the picture area is more colorful, while for the interface other than the picture area in the entire user interface , it is not as bright as the picture area. When the corresponding picture with a narrower color gamut space is displayed on the corresponding user interface with a wider color gamut space, the user will see that the interface other than the picture area in the entire user interface is more gorgeous, while for the picture area, the It's not as gorgeous as the interface other than the picture area.

Therefore, in order to improve the above problems, the inventor proposes a picture display method, device, mobile terminal and storage medium provided by the present application, which can ensure that the color gamut space of the picture and the application program's color gamut space are guaranteed when the picture is displayed in the user interface of the application program. The color gamut space of the user interface is consistent, which improves the display effect.

The following first introduces an application environment applicable to the picture display method provided by the embodiment of the present application.

As shown in FIG. 1 , in the embodiment of the present application, the color gamut conversion processing of the picture in the interface (such as activity) is performed in the canvas (Canvas), and the picture to be subjected to the color gamut conversion will first go through the graphics processing function library (Skia) The corresponding bitmap is obtained by processing, and then color gamut conversion is performed based on the bitmap. In the color gamut conversion process, the color gamut conversion will be performed based on the hardware accelerated drawing module (HWUI) or the graphics processing function library (Skia), and then passed through OpenGL ES (a graphics library), layer module (Surface), layer transfer Module (Surface Flinger), Hardware Layer Mixer (HWC) and Multimedia Display Processor (MDP) processing, and then finally displayed on the screen.

Please refer to FIG. 2. FIG. 2 shows a schematic flowchart of a picture display method provided by an embodiment of the present application. The picture display method shown is used to ensure that the color gamut space of the picture is consistent with the color gamut space of the user interface of the application program when displaying the picture in the user interface of the application program, thereby improving the display effect. In a specific embodiment, the picture display method is applied to the picture display device 400 shown in FIG. 7 and the mobile terminal 100 ( FIG. 11 ) equipped with the picture display device 400 . The following will take a mobile terminal as an example to describe the specific process of this embodiment. Of course, it can be understood that the mobile terminal applied in this embodiment may be an electronic device provided with a display screen, such as a smart phone, a tablet computer, a wearable electronic device, etc. , which is not limited here. The flow shown in FIG. 2 will be described in detail below, and the picture display method may specifically include the following steps:

Step S110: When it is detected that the currently running application program loads the picture, acquire the color gamut space of the picture as the first color gamut space and the color gamut space of the user interface of the application program as the second color gamut space.

In this embodiment of the present application, an application program that can display pictures on its user interface during runtime may be installed in the mobile terminal. Among them, such an application can display the image on the user interface through rendering and other operations after loading the image at runtime. In some embodiments, such an application may also be a picture editing application, such as a Meitu application, etc.; such an application may be a picture viewing application, such as a picture library application, etc.; such an application may also be Chat applications; such applications can also be browsers, etc. Of course, the specific application program that can display pictures on its user interface during running may not be limited.

In some embodiments, when an application program capable of displaying pictures is running, it can load a local picture or a network picture according to a user's selection, a network picture received by the application program, or a picture carried by the application program. For example, as shown in Figure 3, when the application is a picture editing application, the user can select the picture to be edited in the user interface of the application, so that the application will load the picture A2 after loading the picture A2. After rendering, it is displayed on the user interface A1. For another example, when the application is a chat application, the application may receive pictures sent by other users from the server, and the application loads the received pictures before displaying the received pictures. Of course, pictures loaded by specific applications may not be limited.

As a way, the mobile terminal can detect whether the currently running application receives a request to load a picture, so as to determine whether the application is loading the picture. Among them, the image loading request is used for the application to load the image from the local or the server. When the image loading request is to load an image from a server, the image loading request may include a character string identifying the display format of the image requested to be loaded, and the character string may be png, image, jpg and other character strings identifying the image. As another way, when the currently running application calls the interface for loading a picture, it can be determined that the running application loads the picture. Of course, the method of specifically detecting that the currently running application program loads the picture may not be limited.

In some embodiments, when the mobile terminal detects that the currently running application program loads the picture, the mobile terminal may acquire the color gamut space of the picture and the color gamut space of the user interface of the application program, so as to display the picture to the user when the application program displays the picture to the user. Before the interface, determine whether the color gamut space of the picture is the same as the color gamut space of the user interface.

The mobile terminal may acquire the color gamut space of the picture in various ways. As one way, the mobile terminal may acquire a file for describing the color gamut space of a picture, such as an ICC file (color gamut description file). As another method, the EXIF (Exchangeable Image File) information of the loaded picture can be read, and the color gamut space of the picture can be read from the EXIF information, wherein the EXIF information is a format specially set for digital photos. This format can be used to record the attribute information of digital photos, such as the brand and model of the camera, the shooting time of the photo, the aperture set when shooting, shutter speed, ISO and other information and color gamut space. As another method, the color gamut space of the picture can be analyzed directly based on the color values of the pixels of the picture. As a further way, when the EXIF information is generated, an image information accompanying file is also generated. In this file, the information that the picture will be modified later by editing again is stored in this file, for example, the color gamut space or saturation of the picture, etc. The information of the collected picture is then hashed to obtain a globally unique identifier, which is inserted into the image information accompanying file. When the image information is synchronized to the cloud along with the file, when the previously collected picture is displayed on other mobile terminals, even if the picture has been edited again and the information in the EXIF information is no longer the information when it was originally collected (for example, , because the color is edited and the color gamut space changes), other mobile terminals can obtain the image information accompanying file through the cloud to find the information (for example, the color gamut space) when the picture was originally captured, so that it can better Restore the display effect when the image was captured.

There may also be various ways for the mobile terminal to acquire the color gamut of the user interface. As a way, the installation package (Android Package, APK) of the application may include a file for describing the color gamut space of the user interface, such as an ICC file (color gamut description file). As another way, the mobile terminal can also analyze the color value of the pixel points of the user interface when the application program is running in the past, so as to analyze the color gamut space of the picture and store it. When the subsequent application program is running, it needs to obtain When the color gamut space of the user interface is obtained, it is obtained according to the stored information.

Of course, the specific manner in which the mobile terminal obtains the color gamut space of the picture and the color gamut space of the user interface may not be limited.

When the mobile terminal acquires the color gamut space of the picture and the color gamut space of the user interface, the acquired color gamut space of the picture can be used as the first color gamut space; the acquired color gamut space of the picture can be used as the second color gamut space .

Step S120: Determine whether the first color gamut space and the second color gamut space are the same.

In this embodiment of the present application, the acquired first color gamut space and the second color gamut space may be compared to determine whether the first color gamut space and the second color gamut space are the same. As a way, when the color gamuts of the two are obtained through the ICC file, it can be compared whether the parameters in the ICC file are the same to determine whether the first color gamut space and the second color gamut space are the same. As another method, when the first color gamut space and the second color gamut space are obtained, the names of the first color gamut space and the second color gamut space can be obtained, such as SRGB, Adobe RGB, etc., and it is possible to directly compare whether the names are same to determine if the two are the same. Of course, the specific way of judging whether the first color gamut space and the second color gamut space are the same may not be limited.

Step S130: If they are not the same, adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

When it is determined that the first color gamut space is different from the second color gamut space, the mobile terminal may adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

As a method, adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface may include: adjusting the color gamut space of the user interface to the first color gamut space; or adjusting the color gamut space of the picture to the first color gamut space; The color gamut space is adjusted to the second color gamut space. Among them, when the color gamut space of the picture is inconsistent with the color gamut space of the user interface, the color gamut space of one of them is kept unchanged, so that the user interface or the picture can display its original display effect, and the color gamut of both can be displayed. The space is consistent to avoid differences in display effects and affect the user's visual experience.

As another method, the color gamut space of the picture and the color gamut space of the user interface can also be adjusted to a target color gamut space with a larger color gamut range. Of course, the color gamut range of the target color gamut space does not exceed the maximum color gamut range of the display screen.

Of course, the specific way of adjusting the color gamut space of the picture and the color gamut space of the user interface is not limited. For example, the color gamut space of the image and the color gamut space of the user interface can also be adjusted to the target color gamut space with a lower color gamut range.

In some embodiments, before adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface, it may also be determined whether the color gamut adjustment condition is currently satisfied. The color gamut adjustment condition may include a condition indicating whether the resource of the mobile terminal allows the color gamut adjustment. For example, when the remaining power of the mobile terminal is low, performing color gamut adjustment will increase power consumption, so when the remaining power exceeds the set power is only allowed to adjust the color gamut space of the image to be consistent with the color gamut space of the user interface. The color gamut adjustment condition may also include whether the color gamut adjustment function is enabled. The color gamut adjustment function can be enabled or disabled through the configuration interface in the mobile terminal. This function can be applied globally to the mobile terminal or only for a single application. The color gamut adjustment conditions may also include conditions that indicate whether it is necessary to adjust the color gamut space of the picture and the color gamut space of the user interface to be consistent. When the difference in the gamut range is small, it is not necessary to adjust the color gamut space of the picture and the color gamut space of the user interface to be consistent, and the difference between the color gamut range of the first color gamut space and the color gamut range of the second color gamut space is relatively small. When it is large, it is necessary to adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

Step S140: If they are the same, do not adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

When the mobile terminal determines that the first color gamut space is the same as the second color gamut space, it may not adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface, and then directly display the picture.

Step S150: After adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface, display the picture.

In the embodiment of the present application, after the color gamut space of the picture is adjusted to be consistent with the color gamut space of the user interface, the picture can be displayed. In the above process, if the step of adjusting the color gamut space of the picture and the color gamut space of the user interface is consistent, it may be that the color gamut space of the picture has been adjusted; it may also be that the color gamut space of the picture has not been adjusted. Adjustment means adjusting the color gamut space of the user interface, so that the color gamut space of the picture is consistent with the color gamut space of the user interface. Therefore, when the color gamut space of the picture is adjusted, the picture after adjusting the color gamut space is displayed, and when the color gamut space of the picture is not adjusted, the loaded picture can be displayed. In addition, if step S140 is executed, the picture without the adjustment of the color gamut space is directly displayed, that is, the loaded picture is displayed.

The image display method provided by the embodiments of the present application determines whether the color gamut space of the image is the same as the color gamut space of the user interface when the application loads the image, and when the two are different, adjusts the color gamut space of the two to Consistent, you can make sure that the color gamut space of the image is consistent with the color gamut space of the user interface of the application program when displaying the picture in the user interface of the application program, so as to avoid the difference in the display effect and affect the user's visual experience, and improve the display effect and the user's visual experience. visual experience.

Referring to FIG. 4 , FIG. 4 shows a schematic flowchart of a picture display method provided by another embodiment of the present application. The method is applied to the above-mentioned mobile terminal, and the flow shown in FIG. 4 will be described in detail below. The picture display method may specifically include the following steps:

Step S200: When it is detected that the currently running application program loads the picture, acquire the color gamut space of the picture as the first color gamut space and the color gamut space of the user interface of the application program as the second color gamut space.

Step S210: Determine whether the first color gamut space and the second color gamut space are the same.

Step S220: If they are the same, do not adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

In this embodiment of the present application, for steps S200 to S220, reference may be made to the content of the foregoing embodiments, and details are not described herein again.

Step S230: If they are not the same, obtain the current remaining resource parameters of the mobile terminal, wherein the remaining resource parameters include at least one of the remaining power of the mobile mobile terminal, the remaining resources of the central processing unit, and the remaining resources of the graphics processor kind.

In the embodiment of the present application, when the mobile terminal determines that the color gamut space of the picture is the same as the color gamut space of the user interface, the mobile terminal can obtain the current remaining resource parameters of the mobile terminal to determine how to match the color gamut space of the picture with the color gamut space of the user interface. The color gamut space is adjusted to be consistent. The color gamut space of the picture is adjusted to be consistent with the color gamut space of the user interface, which may be adjusting the color gamut space of the picture to the second color gamut space, or adjusting the color gamut space of the user interface to the first color gamut space .

In some embodiments, the current remaining resource parameters of the mobile terminal may include the remaining resources of the central processing unit, the remaining resources of the graphics processor, and the remaining power, etc., and the specific remaining resource parameters may not be limited. The mobile terminal may acquire one or more of these parameters in order to determine how to adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

Wherein, the mobile terminal can detect the usage of the central processing unit to obtain the remaining resources of the central processing unit. For example, when the operating system of the mobile terminal is the Android system, the usage status and process time of the system can be obtained through the ProcessStats class in the Android system. The specific implementation principle is to read the files in the /proc directory. When the system is running, the kernel will update the files in the /proc directory, and write the operation status of the PID into the corresponding file. The remaining resources of the processor. The remaining resources of the central processing unit may be the remaining usage rate of the central processing unit, the remaining usage space, etc., which are not limited herein.

The mobile terminal can also detect the usage of the graphics processor, so as to obtain the remaining resources of the graphics processor. For example, when the operating system of the mobile terminal is Android, the usage of the graphics processor can be obtained through the adb command, for example, the usage of the graphics processor can be obtained through adb shell cat/sys/class/kgsl/kgsl-3d0/gpubusy to Get the remaining resources of the graphics processor. The remaining resources of the graphics processor may be the remaining usage rate of the graphics processor, the remaining usage space, etc., which are not limited herein.

Of course, the above methods for obtaining the remaining resources of the central processing unit and the graphics processor are only examples, and the specific methods may not be limited in the embodiments of the present application.

The mobile terminal can obtain the remaining power of the mobile terminal through a description file for describing the battery state, a monitoring window for monitoring the battery state, etc. in the system. For example, when the system of the mobile terminal is the Android system, the battery events from the bottom layer can be monitored through the Healthd model, and the battery data information can be passed up to the BatteryService of the Framework layer to calculate the battery power-related information, so that the mobile terminal can obtain the battery information from the BatteryService. remaining battery. Of course, the specific way of obtaining the remaining power may not be limited. The remaining power can be the value of the remaining power, the percentage of the remaining power to the total power, etc., which is not limited here.

Step S240: Determine whether the remaining resource parameter is greater than a specified threshold.

In this embodiment of the present application, the specified thresholds corresponding to different types of remaining resource parameters may be different. The remaining resources of the central processing unit may correspond to the first specified threshold, the remaining resources of the graphics processor may correspond to the second specified threshold, and the remaining power may correspond to the third specified threshold. The first specified threshold, the second specified threshold and the third specified threshold can be determined according to the attribute parameters of the central processing unit, the graphics processing unit and the battery respectively. For example, when the maximum operating frequency of the central processing unit is high, the first specified threshold The specified threshold may be 30%, and the specific specified threshold may not be regarded as a limitation.

When the remaining resource parameters obtained by the mobile terminal include multiple types of remaining resource parameters, the remaining resource parameters can be compared with the specified thresholds corresponding to their types to determine whether they are greater than the specified thresholds. When the remaining resource parameters of each type are When the remaining resource parameters of at least one type are not greater than the specified threshold corresponding to its type, it can be determined that the remaining resource parameter of the mobile terminal is greater than the specified threshold, and when the remaining resource parameter of at least one type is not greater than the specified threshold corresponding to its type, then the remaining resource parameter of the mobile terminal is determined. not greater than the specified threshold. Of course, the specific judgment method may not be limited. For example, when the remaining resource parameter of any type is greater than the specified threshold corresponding to its type, it is determined that the remaining resource parameter of the mobile terminal is greater than the specified threshold.

Step S250: When the remaining resource parameter is greater than a specified threshold, compare the color gamut range of the first color gamut space and the color gamut range of the second color gamut space.

In the embodiment of the present application, when it is determined that the remaining resource parameter is greater than the specified threshold, it means that the remaining resources of the mobile terminal allow the color gamut of one of the picture and the user interface to be adjusted to the higher color gamut of the two. color gamut space. It can be understood that when the color gamut space of one of the picture and the user interface is adjusted to the color gamut space with a higher color gamut range among the two, it will increase the burden of the mobile terminal, that is, cause the central processing unit and graphics processing. The occupancy rate of the device, etc. increases, and the power consumption of the mobile terminal will also increase. Therefore, when the remaining resource parameters are relatively high, the color gamut of one of the picture and the user interface can be adjusted to the color gamut range of the two. High color gamut space. Among them, the sum of the colors that can be expressed in different color gamut spaces is different, and the color range is also different, that is, the color gamut range is different.

Further, when the remaining resource parameter is greater than the specified threshold, the color gamut range of the first color gamut space and the color gamut range of the second color gamut space can be compared, that is, the color gamut range of the color gamut space of the current picture and the current user can be compared. The color gamut range of the color gamut space of the interface, so that a color gamut space with a higher color gamut range can be obtained from the first color gamut space and the second color gamut space.

Step S260: If the color gamut range of the first color gamut space is greater than the color gamut range of the second color gamut space, adjust the color gamut space of the user interface to the first color gamut space.

In the embodiment of the present application, when it is compared that the color gamut range of the first color gamut space is greater than the color gamut range of the second color gamut space, it means that the color gamut range of the color gamut space of the current picture is greater than the color gamut range of the current user interface. The color gamut range of the space, so the color gamut space of the user interface can be adjusted to the first color gamut space, so that when the picture is displayed on the user interface, the original color information of the picture can be completed in the color gamut space with a wide color gamut. And because the color gamut space of the two is the same, there is no difference in the display effect between the picture and the user interface, and the display effect is improved.

Step S261: If the color gamut range of the second color gamut space is larger than the color gamut range of the first color gamut space, adjust the color gamut space of the user interface to the first color gamut space.

In the embodiment of the present application, when it is compared that the color gamut range of the second color gamut space is greater than the color gamut range of the first color gamut space, it means that the color gamut range of the color gamut space of the current interface is greater than the color gamut range of the current picture The color gamut range of the space, so the color gamut space of the picture can be adjusted to the second color gamut space, so that when the picture is displayed on the user interface, the original color information of the user interface can be completed in the color gamut space with a wide color gamut. And because the color gamut space of the two is the same, there is no difference in the display effect between the picture and the user interface, and the display effect is improved.

Step S270: When the remaining resource parameter is less than or equal to the specified threshold, compare the color gamut range of the first color gamut space and the color gamut range of the second color gamut space.

When it is judged that the remaining resource parameter is less than or equal to the specified threshold, it means that the remaining resources of the mobile terminal do not allow the color gamut space of one of the picture and the user interface to be adjusted to the color gamut space with a higher color gamut range among the two. , so it is necessary to adjust the color gamut space of the picture or user interface to the color gamut space with the lower color gamut range of the two to ensure that the color gamut space of the two is consistent.

Further, when the remaining resource parameter is less than or equal to the specified threshold, the color gamut range of the first color gamut space and the color gamut range of the second color gamut space can be compared, that is, the color gamut range of the color gamut space of the current picture and The color gamut range of the color gamut space of the current user interface, so that a color gamut space with a lower color gamut range is obtained from the first color gamut space and the second color gamut space.

Step S280: If the color gamut range of the first color gamut space is larger than the color gamut range of the second color gamut space, adjust the color gamut space of the picture to the second color gamut space.

When it is compared that the color gamut range of the first color gamut space is greater than the color gamut range of the second color gamut space, it means that the color gamut range of the color gamut space of the current user interface is lower than the color gamut range of the color gamut space of the current picture, Therefore, the color gamut space of the picture can be adjusted to the second color gamut space, so that the original color information of the user interface can be completely expressed when the picture is displayed on the user interface without increasing the burden on the user terminal. The color gamut space is consistent, so that there is no difference in the display effect between the picture and the user interface, and the display effect is improved.

Step S281: If the color gamut range of the second color gamut space is larger than the color gamut range of the first color gamut space, adjust the color gamut space of the user interface to the first color gamut space.

When it is compared that the color gamut range of the second color gamut space is greater than the color gamut range of the first color gamut space, it means that the color gamut range of the color gamut space of the current picture is lower than the color gamut range of the color gamut space of the current user interface, Therefore, the color gamut space of the user interface can be adjusted to the first color gamut space, so that when the picture is displayed on the user interface, the original color information of the picture can be expressed without increasing the burden on the user terminal. The domain space is consistent, so that there is no difference in the display effect between the picture and the user interface, and the display effect is improved.

Step S290: After adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface, display the picture.

The image display method provided by the embodiment of the present application determines whether the color gamut space of the image is the same as the color gamut space of the user interface when the application loads the image, and when the two are different, determines whether the remaining resource parameters of the user terminal are larger than Specify the threshold value, and adjust the color gamut space of the picture or the user interface according to the dimension of the color gamut space in the case of two different judgment results, so as to ensure the normal operation and use of the mobile terminal, so that it can be displayed in the user interface of the application program. When taking pictures, ensure that the color gamut space of the picture is consistent with the color gamut space of the user interface of the application program, so as to avoid the difference in the display effect and affect the user's visual experience, and improve the display effect and the user's visual experience.

Referring to FIG. 5, FIG. 5 shows a schematic flowchart of a picture display method provided by another embodiment of the present application. This method is applied to the above-mentioned mobile terminal, and the flow shown in FIG. 5 will be described in detail below. The picture display method may specifically include the following steps:

Step S310: When it is detected that the currently running application program loads the picture, acquire the color gamut space of the picture as the first color gamut space and the color gamut space of the user interface of the application program as the second color gamut space.

Step S320: Determine whether the first color gamut space and the second color gamut space are the same.

Step S330: If they are the same, do not adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

In this embodiment of the present application, for steps S310 to S330, reference may be made to the contents of the foregoing embodiments, and details are not described herein again.

Step S340: If they are not the same, obtain the proportion of the display area of the picture in the user interface.

In the embodiment of the present application, when the mobile terminal determines that the color gamut space of the picture is the same as the color gamut space of the user interface, the mobile terminal may obtain the proportion of the display area of the picture in the user interface. The color gamut space of the picture is adjusted to be consistent with the color gamut space of the user interface, which may be adjusting the color gamut space of the picture to the second color gamut space, or adjusting the color gamut space of the user interface to the first color gamut space .

In some implementation manners, the display position and display area corresponding to the picture on the user interface are preset in the application. Therefore, the display area corresponding to the picture on the user interface can be obtained according to the preset settings of the application. For example, a preview area of a picture is preset on a user interface of a picture viewing application, and the preview area is a display area corresponding to the picture on the user interface.

Further, the area of the display area corresponding to the picture on the user interface and the area of the user interface can be obtained, and then the ratio of the area of the display area corresponding to the picture to the area of the user interface can be calculated, so as to obtain that the display area of the picture occupies the user interface. proportion.

Step S350: Determine whether the ratio is greater than a specified ratio.

In the embodiment of the present application, the mobile terminal presets and stores a specified ratio, and the specified ratio is used as a basis for judging the proportion of the display area of the picture in the user interface. After the proportion of the user interface is obtained, the proportion can be compared with the specified proportion to determine whether the proportion of the display area of the picture in the user interface is greater than the specified proportion. It is understandable that when the proportion of the display area of the picture in the user interface is larger than the specified proportion, it means that the corresponding display area of the picture on the user interface is larger, and it can be considered that the user's attention will be more focused on the picture, so the picture can be guaranteed. The original color information can be fully expressed; when the proportion of the display area of the image in the user interface is less than or equal to the specified proportion, it means that the corresponding display area of the image on the user interface is smaller, and the user sees more of the user interface. Therefore, the original color information of the user interface can be fully expressed. In one way, the preset proportion may be 1/2, 2/3, etc., which is not limited herein.

Step S360: When the proportion is greater than a specified proportion, adjust the color gamut space of the user interface to the first color gamut space.

In some embodiments, when it is determined that the proportion of the display area of the picture in the user interface is greater than a specified proportion, it can be ensured that the original color information of the picture can be fully expressed, so the color gamut of the user interface is adjusted to the first color gamut space, so that the color gamut space of the picture is the same as the color gamut space of the user interface.

Step S370: When the ratio is less than or equal to the specified ratio, adjust the color gamut space of the picture to the second color gamut space.

In some embodiments, when it is determined that the proportion of the display area of the picture in the user interface is less than or equal to a specified proportion, it can be ensured that the original color information of the user interface can be fully expressed, so the color gamut of the picture is adjusted to the second Color gamut space, so that the color gamut space of the picture is the same as the color gamut space of the user interface.

Step S380: After adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface, display the picture.

The image display method provided by the embodiment of the present application determines whether the color gamut space of the image is the same as the color gamut space of the user interface when the application loads the image, and when the two are different, according to the display area of the image occupying the user interface Proportion size, determine to adjust the color gamut space of the picture or adjust the color gamut space of the user interface, so that the color gamut space of the picture is consistent with the color gamut space of the user interface, so that when the picture is displayed in the user interface of the application program , to ensure that the color gamut space of the picture is consistent with the color gamut space of the user interface of the application, and to ensure that most of the displayed content can present the original color information, so as to avoid the difference in display effect affecting the user's visual experience, and to improve the display effect and user experience. visual experience.

Referring to FIG. 6, FIG. 6 shows a schematic flowchart of a picture display method provided by still another embodiment of the present application. This method is applied to the above-mentioned mobile terminal, and the flow shown in FIG. 6 will be described in detail below. The picture display method may specifically include the following steps:

Step S400: When it is detected that the currently running application program loads the picture, acquire the color gamut space of the picture as the first color gamut space and the color gamut space of the user interface of the application program as the second color gamut space.

Step S410: Determine whether the first color gamut space and the second color gamut space are the same.

Step S420: If they are the same, do not adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

In this embodiment of the present application, for steps S400 to S420, reference may be made to the contents of the foregoing embodiments, and details are not described herein again.

Step S430: If they are not the same, determine whether the number of pictures loaded by the application program is multiple.

As one way, adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface may include: adjusting the color gamut space of the user interface to the first color gamut space.

In this embodiment of the present application, when the mobile terminal determines that the color gamut space of the picture is the same as the color gamut space of the user interface, the mobile terminal may acquire the number of pictures loaded by the application program. It is understandable that when an application loads an image, it may load multiple images at the same time, that is, there are multiple images that need to be displayed on the user interface.

Further, the mobile terminal can determine whether the number of pictures loaded by the application program is multiple, so as to determine whether to adjust the color gamut space of the user interface to the first color gamut space. When the number of pictures loaded by the application program is multiple, if the mobile terminal adjusts the color gamut space of the user interface to the first color gamut space for each picture, the mobile terminal will have to process many tasks.

Step S440: If there are multiple images, determine whether the color gamut spaces of the multiple images are the same.

In the embodiment of the present application, when the number of pictures loaded by the application program is multiple, since the mobile terminal adjusts the color gamut space of the user interface to the first color gamut space for each picture, the task of processing the mobile terminal will be caused. more, which may affect the normal use of the mobile terminal. Therefore, it can be determined whether the color gamut spaces of multiple pictures are the same, that is, whether the color gamut spaces of multiple pictures are the same color gamut space. It can be understood that when the color gamut spaces of multiple pictures are the same, the mobile terminal only needs to adjust the color gamut space of the user interface to the first color gamut space once, without bringing a burden to the mobile terminal. When the color gamut spaces of multiple pictures are different, it is not necessary to adjust the color gamut space of the user interface to the first color gamut space, so as to reduce the burden on the mobile terminal.

Step S450: If the color gamut spaces of the multiple pictures are the same, adjust the color gamut space of the user interface to the first color gamut space.

Step S460: If the color gamut spaces of the plurality of pictures are different, do not adjust the color gamut space of the user interface to the first color gamut space.

Step S470: If there are not more than one, display prompt content, where the prompt content is used to prompt whether to adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

In the embodiment of the present application, when the number of pictures loaded by the application program is not multiple, that is, when the picture loaded by the application program is a single picture, before the color gamut space of the picture is adjusted to be consistent with the color gamut space of the user interface, the The prompt content may be displayed to prompt the user whether to adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface, that is, whether to adjust the color gamut space of the user interface to the first color gamut space. It is understandable that when the number of images loaded by an application is a single image, it is possible that the image displayed by the application is only one image. If the color gamut space of the user interface is adjusted to the first color gamut space, the subsequent The color gamut space of the user interface is adjusted back to the second color gamut space, which makes the whole process more complicated. Adjusting the color gamut space of the user interface just to view a single picture may not be necessary for some users, so you can prompt User, the user decides whether to adjust the color gamut space of the user interface to the first color gamut space. The prompt content may be implemented in the form of a pop-up window, etc., which is not limited here.

Step S480: When receiving the determination instruction, adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface.

In some embodiments, after displaying the prompt content, you can wait for an instruction input by the user. When a confirmation instruction is detected, it means that the user needs to adjust the color gamut space of the picture to be consistent with the color gamut space of the user interface, that is, set the The color gamut space of the user interface is adjusted to the first color gamut space. However, when the determination instruction is not detected, the adjustment of the color gamut space of the user interface to the first color gamut space is not performed. Wherein, it may be determined whether a determination instruction is received according to the detected operation on the prompt content in the user interface. For example, when prompted by the pop-up window, "Yes" and "No" controls may be displayed, and when an operation on the "Yes" control is detected, it is determined that a determination instruction is received. In addition, when the pop-up window prompts, you can also adjust the color gamut of the user interface and count down. When the user fails to confirm the operation within the target time after the pop-up window prompt, the pop-up window prompt is canceled, and the user interface is not executed. The color gamut space is adjusted to the first color gamut space.

Step S490: After adjusting the color gamut space of the picture to be consistent with the color gamut space of the user interface, display the picture.

The image display method provided by the embodiment of the present application determines whether the color gamut space of the image is the same as the color gamut space of the user interface when the application program loads the image, and when the two are different, determines the number of loaded images, and when the image is loaded When there are multiple pictures, the color gamut space of the multiple pictures is the same. Adjust the color gamut space of the user interface to be consistent with the color gamut space of the picture, reduce the load and power consumption of the mobile terminal, and make the application program When displaying pictures in the user interface of the application, ensure that the color gamut space of the picture is consistent with the color gamut space of the user interface of the application, and ensure that most of the displayed content can present the original color information, so as to avoid the difference in display effect and affect the user's vision. experience, improve the display effect and the user's visual experience.
