Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to 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 pictures with higher definition in the user interface of the application program. However, the inventor finds in research that factors affecting the picture display effect include, in addition to the information of the picture itself, the degree of matching between the picture information and the user interface and display screen of the application program.
Take the color gamut space as an example. A color gamut, i.e. a color gamut space, is a method of encoding a color and also refers to the sum of colors that a technical system is capable of producing. In computer graphics processing, a color gamut is some complete subset of colors. The color gamut space may include an sRGB color gamut, an Adobe RGB color gamut, or a DCI-P3 color gamut. Among them, sRGB is one of the earliest color gamut standards and is supported by W3C, exif, intel, pantone, corel and many other industry vendors from the industry. The Adobe RGB gamut mainly improves the display on the cyan-green system and therefore presumably covers 50% of the cie 1931XYZ color space. DCI-P3 is a color gamut applied to digital cinema, which is a color gamut standard dominated by human visual experience and matches as much as possible all the color gamuts that can be exhibited in a movie scene. It is also not the broadest standard in color gamut (bt.2020 is the most recent standard at present), but has a broader red/green family range above the rec.709 standard.
The inventor finds that, when the color gamut space of the picture is not consistent with the color gamut space of the display screen, directly displaying the picture with the inconsistent color gamut space on the display screen may cause a display effect that the picture cannot be originally acquired when the picture is displayed, and in addition, when the picture is displayed in a user interface of an application program (for example, a user views a picture sent by an opposite party in a chat application), directly displaying the picture with the inconsistent color gamut space on the user interface when the color gamut space of the picture is not consistent with the color gamut space of the user interface of the application program, may cause a display effect that a region where the picture is located on a display region is not consistent with a region where the user interface is located, and may affect the display effect. For example, when a picture with a wider color gamut space is displayed on a user interface with a narrower color gamut space, the user may see the picture area more gorgeous, but the image area is less gorgeous for the interfaces except the picture area in the whole user interface. When a picture with a narrower color gamut space is displayed on a user interface with a wider color gamut space, a user can see that the interface except for the picture area in the whole user interface is more gorgeous, and the image area is less gorgeous than the interface except for the picture area. As another example, when a picture corresponding to a wider color gamut space is displayed on a display screen corresponding to a narrower color gamut space, the displayed picture may become more oversaturated.
Therefore, in order to improve the above problem, the inventor proposes a picture display method, a device, a mobile terminal and a storage medium provided by the present application, so that when a picture is displayed in a user interface of an application program, it is ensured that a color gamut space of the picture, a color gamut space of a display screen and a color gamut space of the user interface of the application program are consistent, thereby improving a display effect.
An application environment suitable for the image display method provided by the embodiment of the present application is described below.
As shown in fig. 1, in the embodiment of the present application, a color gamut conversion process of a picture in an interface (e.g., activity) is performed in a Canvas (Canvas), and the picture to be subjected to the color gamut conversion is first subjected to a processing of a graphics processing function library (Skia) to obtain a corresponding bitmap, and then subjected to the color gamut conversion based on the bitmap. In the process of color gamut conversion, color gamut conversion is performed based on a hardware accelerated graphics (HWUI) or a graphics processing function library (Skia), and then the color gamut conversion is processed by an OpenGL ES (graphics library), a layer module (Surface), a layer transfer module (Surface flipper), a hardware layer mixer (HWC) and a Multimedia Display Processor (MDP), and finally displayed on a display screen.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a picture display method according to an embodiment of the present application. The picture display method is used for ensuring that the color gamut space of the picture is consistent with the color gamut space of the display screen and the user interface when the picture is displayed in the user interface of the application program, so that the display effect is improved. In a specific embodiment, the picture display method is applied to the picture display apparatus 400 shown in fig. 6 and the mobile terminal 100 (fig. 9) configured with the picture display apparatus 400. The following will describe a specific process of this embodiment by taking a mobile terminal as an example, and it is 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, and a wearable electronic device, and is not limited herein. As will be described in detail with respect to the flow shown in fig. 2, the image display method may specifically include the following steps:
step S110: when it is detected that a currently running application program loads a picture, acquiring a color gamut space of the picture as a first color gamut space and acquiring a color gamut space of a user interface of the application program as a second color gamut space.
In the embodiment of the application, an application program which can display pictures on a user interface when running can be installed in the mobile terminal. After the pictures are loaded during running, the application programs can display the pictures on the user interface through operations such as rendering and the like. In some embodiments, such an application may also be a photo editing type application, such as a beauty application or the like; such applications may be picture viewing type applications, such as a picture library application or the like; such applications may also be chat applications; such an application may also be a browser or the like. Of course, the application program that may present the pictures at its user interface at runtime may be particularly non-limiting.
In some embodiments, when the application program capable of displaying the picture runs, the local picture or the network picture may be loaded according to the selection of the user, the network picture received by the application program may also be loaded, and the picture carried by the application program may also be loaded. For example, as shown in fig. 3, when the application is a picture editing application, a user may select a picture to be edited in a user interface of the application, so that after the application loads a picture A2, the loaded picture A2 is rendered and displayed on the user interface A1. For another example, when the application is a chat-type application, the application may receive a picture sent by another user from the server, and the application may load the received picture before displaying the picture. Of course, the pictures loaded by a specific application program may not be limiting.
As one way, the mobile terminal may detect whether a loading request for a picture is received by a currently running application to determine whether the application is loading the picture. The picture loading request is used for loading the picture from a local or server by the application program. When the picture loading request is to load a picture from the server, the picture loading request may include a character string for identifying a display format of the picture requested to be loaded, where the character string may be a character string for marking the picture, such as png, image, jpg, and the like. As another way, when the currently running application calls the interface for loading the picture, it may be determined that the running application loads the picture. Of course, the specific manner of detecting that the currently running application program loads the picture may not be limited.
In some embodiments, when detecting that a currently running application loads a picture, the mobile terminal may obtain a color gamut space of the picture and a color gamut space of a user interface of the application to 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 obtain the color gamut space of the picture in various ways. As one way, the mobile terminal may acquire a file for describing a color gamut space of a picture, such as an ICC file (color gamut description file). Alternatively, EXIF (Exchangeable Image File) information of a loaded picture, which is a format specifically set for digital photographs, may be read out, and a color gamut space of the picture may be read out from the EXIF information. Such a format can be used to record attribute information of digital photographs, such as the brand and model of a camera, the photographing time of a photograph, the size of an aperture set at the time of photographing, shutter speed, ISO, and the like, and color gamut space, and the like. As another way, the color gamut space of the picture can be analyzed directly based on the color values of the pixel points of the picture. As still another mode, the EXIF information is generated together with an image information accompanying file. In this file is stored information that the picture will subsequently be modified for re-editing, e.g. the gamut space or saturation of the picture, etc. And then carrying out hash operation on the acquired picture information to obtain a globally unique identifier, and inserting the identifier into the image information accompanying file. And the image information accompanying file is synchronized to the cloud end, so that when the acquired picture is displayed on other mobile terminals, even if the picture is edited again and the information in the EXIF information is not the information when the picture is initially acquired (for example, color gamut space changes due to color editing), other mobile terminals can acquire the image information accompanying file through the cloud end to find the information when the picture is initially acquired (for example, color gamut space), so that the display effect when the picture is acquired can be better recovered.
The way in which the color gamut of the user interface is obtained by the mobile terminal may also be various. As one way, an installation package (APK) of the application may include therein a configuration file, such as an ICC file (color gamut description file), for describing a color gamut space of the user interface. As another mode, the mobile terminal may also analyze color values of pixel points of the user interface when the application program runs in the past, so as to analyze and store the color gamut space of the picture, and acquire the color gamut space of the user interface according to the stored information when the subsequent application program runs and the color gamut space of the user interface needs to be acquired.
Of course, the manner in which the mobile terminal specifically acquires 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 a first color gamut space; the color gamut space of the obtained picture may be used as the second color gamut space.
Step S120: and if the first color gamut space is different from the second color gamut space, acquiring a third color gamut space of the display screen of the mobile terminal.
In this embodiment, the obtained 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 one way, when the color gamuts of both are acquired through the ICC file, it is possible to compare 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. Alternatively, when the first color gamut space and the second color gamut space are obtained, names of the first color gamut space and the second color gamut space, such as SRGB, adobe RGB, and the like, may be obtained, and whether the names are the same may be directly compared to determine whether the names are the same. Of course, the specific manner of determining whether the first color gamut space and the second color gamut space are the same may not be limited.
Further, when it is determined that the first color gamut space is different from the second color gamut space, the mobile terminal may obtain a third color gamut space of the display screen. As one way, a file may be configured in the system of the mobile terminal for storing the current color gamut space of the display screen, for example, an ICC file may be configured in the system of the mobile terminal. Therefore, the mobile terminal can acquire the color gamut space of the display screen by reading the file, and use the acquired color gamut space of the display screen as a third color gamut space. Of course, the manner of obtaining the color gamut space of the display screen may not be limiting.
In some embodiments, when it is determined that the first color gamut space is the same as the second color gamut space, the mobile terminal may not perform color gamut space conversion on the picture, the user interface, or the display screen, and then directly display the picture.
Of course, in some embodiments, when it is determined that the first color gamut space is the same as the second color gamut space, the color gamut space of the display screen may also be obtained as a third color gamut space, and whether the third color gamut space is the same as the first color gamut space or the second color gamut space is compared. As one way, if the third color gamut space is not the same as the first color gamut space or the second color gamut space, the color gamut space of the display screen may be converted into the first color gamut space or the second color gamut space so that the color gamut spaces of the picture, the user interface, and the display screen are the same. As another way, if the third color gamut space is different from the first color gamut space or the second color gamut space, the color gamut space of the picture and the user interface may also be converted into the third color gamut space, so that the color gamut spaces of the picture, the user interface, and the display screen are the same.
Step S130: and if the second color gamut space is the same as the third color gamut space, adjusting the color gamut space of the picture to be the second color gamut space or the third color gamut space.
In an embodiment of the present application, the second gamut space and the third gamut space may be compared to determine whether the first gamut space and the second gamut space are the same. The mobile terminal may also determine whether the first color gamut space is the same as the second color gamut space by obtaining a configuration file or a name, etc. obtained when the color gamut space of the user interface and the display screen is obtained.
Further, if the second color gamut space is the same as the third color gamut space, the color gamut space of the picture may be adjusted to the second color gamut space or the third color gamut space. It can be understood that, when the mobile terminal runs the application and displays the user interface, the user interface may be displayed in the same color gamut space as the display screen, and if the color gamut space of the current display screen is the same as the display space of the user interface, the color gamut space of the picture only needs to be adjusted to be the same as the color gamut space of the user interface and the user interface, so that the color gamut space of the picture, the user interface, and the display screen is the same. Therefore, the mobile terminal does not need to adjust the color gamut space of the display screen and the user interface, and the processing efficiency of the mobile terminal is improved.
In some embodiments, before adjusting the color gamut space of the picture to the second color gamut space or the third color gamut space, 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 color gamut adjustment, for example, when the remaining power of the mobile terminal is low, performing color gamut adjustment may increase power consumption, and therefore when the remaining power exceeds the set power, the color gamut space of the picture is allowed to be adjusted to the second color gamut space or the third color gamut space. The color gamut adjusting condition may also include whether a function for characterizing color gamut adjustment is turned on, the function for color gamut adjustment may be turned on or off by a configuration interface in the mobile terminal, and the function may be global to the mobile terminal or may be only specific to a single application. Of course, the specific color gamut adjustment conditions may not be limiting.
In some embodiments, if the second color gamut space is different from the third color gamut space, the color gamut spaces of any two of the picture, the user interface, and the display screen may be adjusted to be the same as the color gamut spaces of the rest, so that the color gamut spaces of the three are the same. As one way, both the color gamut space of the picture and the color gamut space of the user interface may be adjusted to the third color gamut space. As another way, both the color gamut space of the user interface and the color gamut space of the display screen may be adjusted to the first color gamut space. As another way, both the color gamut space of the picture and the color gamut space of the display screen may be adjusted to the second color gamut space.
Step S140: and displaying the adjusted picture.
According to the picture display method provided by the embodiment of the application, when the picture is loaded by the application program, whether the color gamut space of the picture is the same as that of the user interface or not is judged, and when the color gamut space of the user interface is different from that of the display screen, whether the color gamut space of the user interface is consistent with that of the display screen or not is determined, and when the color gamut space of the user interface is the same as that of the display screen, the color gamut space of the picture, the color gamut space of the user interface and the color gamut space of the display screen are adjusted to be the color gamut space of the user interface or the color gamut space of the display screen.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a picture display method according to another embodiment of the present application. The method is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 4, where the image display method may specifically include the following steps:
step S210: when it is detected that a currently running application program loads a picture, acquiring a color gamut space of the picture as a first color gamut space and acquiring a color gamut space of a user interface of the application program as a second color gamut space.
Step S220: and if the first color gamut space is different from the second color gamut space, acquiring a third color gamut space of the display screen of the mobile terminal.
In the embodiment of the present application, the contents of step S210 and step S220 may refer to the contents of the foregoing embodiments, and are not described herein again.
Step S230: and if the second color gamut space is the same as the third color gamut space, comparing the color gamut range of the first color gamut space with the color gamut range of the second color gamut space.
In the embodiment of the present application, when it is determined that the second gamut space is the same as the third gamut space, the gamut range of the first gamut space may be compared with the gamut range of the second gamut space. It can be understood that, when the gamut range of the gamut space of the user interface is greater than the gamut range of the gamut space of the picture, if the gamut space of the picture is adjusted to be the higher second gamut space and the higher third gamut space, the load of the mobile terminal may be increased, that is, the occupancy rate of the central processor, the graphics processor, and the like may be increased, and the power consumption of the mobile terminal may also be increased, so that the gamut range of the gamut space of the user interface may be compared with the gamut range of the gamut space of the picture, that is, the gamut range of the first gamut space may be compared with the gamut range of the second gamut space, to determine whether to subsequently adjust the gamut space of the picture to be the higher second gamut space or the higher third gamut space. The sum of colors that can be expressed by different color gamut spaces is different, and the color rendering range is also different, that is, the color gamut range is different.
Of course, since the color gamut space of the user interface is the same as the color gamut space of the display screen, the mobile terminal may also compare the color gamut space of the picture with the color gamut space of the display screen, that is, compare the first color gamut space with the third color gamut space.
Step S240: and if the color gamut range of the second color gamut space is larger than the color gamut range of the first color gamut space, acquiring the current residual resource parameter of the terminal, wherein the residual resource parameter comprises at least one of the residual electric quantity of the terminal, the residual resource of a central processing unit and the residual resource of a graphic processor.
In this embodiment of the application, if the comparison result is that the color gamut range of the second color gamut space is larger than the color gamut range of the first color gamut space, the burden of the mobile terminal may be increased if the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space. Therefore, the current remaining resource parameters of the mobile terminal can be obtained to determine how to adjust the color gamut space of the picture to the second color gamut space or the third color gamut space with a higher color gamut range.
In some embodiments, the current remaining resource parameter of the mobile terminal may include a remaining resource of the central processing unit, a remaining resource of the graphics processing unit, a remaining power, and the like, and the specific remaining resource parameter may not be limited. The mobile terminal may obtain 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.
The mobile terminal can detect the use condition of the central processing unit to obtain the residual resources of the central processing unit. For example, when the operating system of the mobile terminal is an Android system, the service condition and the process time of the system can be obtained through a ProcessStats class in the Android system. The specific implementation principle is that files in a/proc directory are read, when the system runs, the kernel updates the files in the/proc directory, the running condition of the PID is written into the corresponding files, and the residual resources of the central processing unit can be obtained according to the running condition. The remaining resource of the central processing unit may be a remaining utilization rate, a remaining usage space, and the like of the central processing unit, which is not limited herein.
The mobile terminal can also detect the use condition of the graphics processor, thereby obtaining the residual resources of the graphics processor. For example, when the operating system of the mobile terminal is an android system, the usage of the graphics processor may be obtained through an adb command, for example, the usage of the graphics processor may be obtained through adb shell cat/sys/class/kgsl/kgsl-3d0/gpubusy, so as to obtain the remaining resources of the graphics processor. The remaining resources of the graphics processor may be, but are not limited to, a remaining usage rate, a remaining usage space, and the like of the graphics processor.
Of course, the above manner of obtaining the remaining resources of the central processing unit and the graphics processor is only an example, and the specific manner may not be limited in the embodiment of the present application.
The mobile terminal can acquire the residual electric quantity of the mobile terminal through a description file for describing the battery state, a monitoring window for monitoring the battery state and the like in the system. For example, when the system of the mobile terminal is an android system, the battery event from the bottom layer can be monitored through a health model, and battery data information is transmitted upwards to the battery service of the Framework layer to calculate the battery power related information, so that the mobile terminal can obtain the remaining power of the battery from the battery service. Of course, the specific manner of acquiring the remaining power may not be limited. The remaining capacity may be a remaining capacity value, a percentage of the remaining capacity to the total capacity, and the like, and is not limited herein.
Step S250: and judging whether the residual resource parameter is larger than a first specified threshold value.
In this embodiment of the present application, the first specified thresholds corresponding to different types of remaining resource parameters may be different. The remaining resources of the central processing unit may correspond to a designated threshold 1, the remaining resources of the graphics processing unit may correspond to a designated threshold 2, and the remaining power may correspond to a designated threshold 3. The designated threshold 1, the designated threshold 2, and the designated threshold 3 may be determined according to the attribute parameters of the central processing unit, the graphic processing unit, and the battery, for example, when the maximum operating frequency of the central processing unit is relatively high, the designated threshold 1 may be 30%, and the specific first designated threshold may not be limited.
When the remaining resource parameters acquired by the mobile terminal include multiple types of remaining resource parameters, the remaining resource parameters may be respectively compared with the specified threshold corresponding to the types of the remaining resource parameters to determine whether the remaining resource parameters are greater than a first specified threshold, when the remaining resource parameters of each type are greater than the first specified threshold corresponding to the type of the remaining resource parameters, the remaining resource parameters of the mobile terminal may be determined to be greater than the first specified threshold, and when the remaining resource parameters of at least one type are not greater than the first specified threshold corresponding to the type of the remaining resource parameters, the remaining resource parameters of the mobile terminal are determined to be not greater than the specified threshold. Of course, the specific determination manner may not be limited, for example, it may also be determined that the remaining resource parameter of the mobile terminal is greater than the first specified threshold when the remaining resource parameter of any type is greater than the first specified threshold corresponding to the type.
Step S260: and if the residual resource parameter is larger than a first specified threshold value, adjusting the color gamut space of the picture to be the second color gamut space or the third color gamut space.
In this embodiment of the application, when it is determined that the remaining resource parameter is greater than the specified threshold, it indicates that the remaining resource of the mobile terminal allows the color gamut space of the picture to be adjusted to the second color gamut space or the third color gamut space with a higher color gamut range. It can be understood that, when the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space with a higher color gamut range, the load of the mobile terminal may be increased, that is, the occupancy rate of the central processing unit, the graphics processing unit, and the like is increased, and the power consumption of the mobile terminal may also be increased, so that when the remaining resource parameter is higher, the color gamut space of the picture may be adjusted to the second color gamut space or the third color gamut space with a higher color gamut range.
Step S261: and if the residual resource parameter is less than or equal to the first specified threshold, acquiring the proportion of the display area of the picture in the user interface.
In the embodiment of the present application, when it is determined that the remaining resource parameter is less than or equal to the specified threshold, it indicates that if the color gamut space of the picture is currently adjusted to the second color gamut space or the third color gamut space with a higher color gamut range, a jam and an insufficient power of the mobile terminal may be caused. In this case, it may be considered whether the occupation ratio of the display area of the picture to the user interface is high, and if the occupation ratio is high, it indicates that the display area of the picture is large, and the mobile terminal may not adjust the color gamut space of the picture to the second color gamut space or the third color gamut space with a large color gamut range in order to avoid the stuttering and the power shortage of the mobile terminal. Therefore, the mobile terminal can acquire the occupation ratio of the display area of the picture to the user interface.
In some embodiments, the application program is preset with a display position and a display area of the picture on the user interface. Therefore, the corresponding display area of the picture on the user interface can be acquired according to the preset of the application program. For example, a preview area of a picture is preset on a user interface of a picture viewing application program, and the preview area is a display area corresponding to the picture on the user interface.
Further, the area of the display region 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 region corresponding to the picture to the area of the user interface is calculated, so that the occupation ratio of the display region of the picture to the user interface is obtained.
Step S270: and judging whether the ratio is larger than a specified ratio.
In the embodiment of the application, the mobile terminal is preset and stores the specified proportion, and the specified proportion is used as a judgment basis for the proportion of the display area of the picture occupying the user interface. It can be understood that, when the occupation ratio of the display area of the picture to the user interface is greater than the specified ratio, it indicates that the corresponding display area of the picture on the user interface is larger, so as not to affect the work of the mobile terminal, the color gamut space of the picture may not be adjusted to the color gamut space with the larger color gamut range, but the color gamut space of the user interface and the color gamut space of the display screen may be adjusted to the first color gamut space with the lower color gamut range, thereby ensuring the color gamut spaces of the picture, the user interface and the display screen to be consistent, and ensuring the original color information of the picture to be completely expressed; when the occupation ratio of the display area of the picture to the user interface is smaller than or equal to the designated ratio, the corresponding display area of the picture on the user interface is smaller, the color gamut range of the picture is adjusted to the color gamut space with the higher color gamut range, and the work of the mobile terminal is probably not influenced, so that the color gamut range of the picture can be adjusted to the second color gamut space or the third color gamut space, the consistency of the color gamut spaces of the picture, the user interface and the display screen is ensured, and the original color information of the user interface can be completely expressed. In one aspect, the predetermined ratio may be 1/2, 2/3, etc., and is not limited herein.
Step S280: and if the ratio is larger than a specified ratio, adjusting the color gamut space of the display screen and the color gamut space of the user interface to the first color gamut space.
Step S281: and if the ratio is less than or equal to the specified ratio, adjusting the color gamut space of the picture to be the second color gamut space or the third color gamut space.
In some embodiments, after step S230, if the gamut range of the first gamut space is greater than the gamut range of the second gamut space and the remaining resource parameter is greater than a second specified threshold, the mobile terminal may adjust the gamut space of the display screen and the gamut space of the user interface to the first gamut space, where the second specified threshold is greater than the first specified threshold, for example, 50% of the first specified threshold is 30%. It can be understood that if the remaining resource parameter of the mobile terminal is greater than the second specified threshold, the remaining resource of the mobile terminal is more, so that the color gamut space of the display screen and the color gamut space of the user interface can be simultaneously adjusted to the first color gamut space with a higher color gamut range, without affecting the normal operation of the mobile terminal.
Step S290: and when the color gamut space of the picture is not adjusted, displaying the picture, and when the color gamut space of the picture is adjusted, displaying the adjusted picture.
In the embodiment of the present application, in the above process, the color gamut space of the picture may be adjusted; it may also be that the color gamut space of the picture is not adjusted, that is, the color gamut spaces of the user interface and the display screen are adjusted, so that the color gamut space of the picture is consistent with the color gamut spaces of the user interface and the display screen. Therefore, when the color gamut space of the picture is adjusted, the picture with the adjusted color gamut space is displayed, and when the color gamut space of the picture is not adjusted, the picture loaded by the application program can be displayed.
According to the picture display method provided by the embodiment of the application, when the picture is loaded by the application program, whether the color gamut space of the picture is the same as that of the user interface is judged, and when the color gamut space of the user interface is different from that of the display screen, whether the color gamut space of the user interface is the same as that of the display screen is judged, whether the color gamut range of the color gamut space of the picture is larger than that of the color gamut space of the user interface is judged, under the condition of two different judgment results, the color gamut space of the picture is adjusted according to the residual resource parameters of the mobile terminal, or the color gamut spaces of the user interface and the display screen are adjusted, so that the normal operation and the use condition of the mobile terminal are ensured, when the picture is displayed in the user interface of the application program, the color gamut space of the picture is consistent with the color gamut spaces of the user interface and the display screen, the difference in the display effect is avoided, the user visual experience is influenced, and the display effect and the user visual experience are improved.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a picture display method according to another embodiment of the present application. The method is applied to the mobile terminal, and as will be described in detail below with respect to the flow shown in fig. 5, the image display method may specifically include the following steps:
step S310: when detecting that a currently running application program loads a picture, acquiring a color gamut space of the picture as a first color gamut space and acquiring a color gamut space of a user interface of the application program as a second color gamut space
Step S320: and if the first color gamut space is different from the second color gamut space, acquiring a third color gamut space of the display screen of the mobile terminal.
In the embodiment of the present application, step S310 and step S320 may refer to the contents of the foregoing embodiments, and are not described herein again.
Step S330: and if the second color domain space is the same as the third color domain space, judging whether the number of the pictures loaded by the application program is multiple.
In this embodiment of the application, before the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space, the mobile terminal may further obtain the number of pictures loaded by the application program. It can be understood that when the application program loads the pictures, it may load a plurality of pictures at the same time, that is, a plurality of pictures need to be displayed on the user interface.
Further, the mobile terminal may determine whether the number of the pictures loaded by the application program is multiple, so as to determine whether to adjust the color gamut space of the pictures to the second color gamut space or the third color gamut space. When the number of the pictures loaded by the application program is multiple, if the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space for each picture by the mobile terminal, the task processed by the mobile terminal is more.
Step S340: if not, the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space.
In the embodiment of the application, when the number of the pictures loaded by the application program is not multiple, the color gamut space of the pictures is adjusted to the second color gamut space or the third color gamut space, so that the normal work of the mobile terminal is prevented from being influenced by too many processing tasks of the mobile terminal.
Step S350: and if the number of the color gamut spaces is multiple, displaying prompt contents, wherein the prompt contents are used for prompting whether the color gamut space of the picture is adjusted to be the second color gamut space or the third color gamut space.
In this embodiment of the application, when the number of the pictures loaded by the application is multiple, before the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space, a prompt content may be further displayed to prompt a user whether to adjust the color gamut space of the picture to the second color gamut space or the third color gamut space. It can be understood that when the number of the pictures loaded by the application is more than one, the processing task of the mobile terminal may be too much and the operation may not be smooth, so that the user may be prompted to decide whether to adjust the color gamut space of the pictures to the second color gamut space or the third color gamut space. The prompt content may be implemented in the form of a pop-up window, and is not limited herein.
Step S360: when a determination instruction is received, the color gamut space of the picture is adjusted to the second color gamut space or the third color gamut space.
In some embodiments, after the hint content is displayed, an instruction input by the user may be waited, and when a determination instruction is detected, it indicates that the user needs to adjust the color gamut space of the picture to the second color gamut space or the third color gamut space. And when the determination instruction is not detected, the color gamut space of the picture is not adjusted to the second color gamut space or the third color gamut space. Wherein, whether the determination instruction is received or not can be determined according to the detected operation on the prompt content in the user interface. For example, when the pop-up prompt is performed, controls of "yes" and "no" may be displayed, and when an operation on the control of "yes" is detected, it is determined that the determination instruction is received. In addition, when the pop-up window prompt is performed, countdown can be performed, when the user does not perform the confirmation operation within the target duration after the pop-up window prompt, the pop-up window prompt is cancelled, and the color gamut space of the picture is not adjusted to the second color gamut space or the third color gamut space.
Step S370: and displaying the adjusted picture.
The picture display method provided by the embodiment of the application judges whether the color gamut space of the picture is the same as that of the user interface when the picture is loaded by the application, determines whether the color gamut space of the user interface is the same as that of the display screen when the picture is loaded by the application, determines the number of the loaded pictures when the color gamut space of the user interface is the same as that of the display screen, adjusts the color gamut space of the picture into the second color gamut space or the third color gamut space when the loaded picture is not multiple pictures, avoids influencing the normal work of the mobile terminal, ensures that the color gamut space of the picture is the same as that of the user interface of the application and the color gamut space of the display screen when the picture is displayed in the user interface of the application, avoids the difference in display effect, ensures that the picture can present original color information, and improves the display effect and the visual experience of a user.
