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. However, the inventor finds in long-term 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 of the picture display screen or the application program.
Take color space as an example. A color gamut, i.e. a color 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 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 can cover approximately 50% of the CIE1931XYZ color space. DCI-P3 is a color gamut applied to digital cinema, which is a color gamut standard that dominates the human visual experience and matches as closely as possible the full color gamut that can be exhibited in a movie scene. It is also not the broadest standard in color gamut (bt.2020 is the current latest standard), but has a broader red/green family range above the rec.709 standard.
The inventor finds that when the color space of the picture is inconsistent with the color space of the display screen or the user interface of the application program, the picture with the inconsistent color space is directly displayed on the display screen or the user interface, so that the display effect of the picture which is originally acquired cannot be displayed. For example, when a picture corresponding to a wider color space is displayed on a display screen corresponding to a narrower color space, the displayed picture may become more oversaturated. When a picture with a narrower color space is displayed on a display screen with a wider color gamut space, the displayed picture becomes darker. Meanwhile, the inventor finds that power consumption of the mobile terminal is caused in the process of converting the color space of the picture, and particularly, the problem that processing resources are tense and are blocked is caused in the process of converting the color space of the picture through the central processing unit.
Therefore, in order to solve the above problem, the inventor proposes a picture processing method, an apparatus, a mobile terminal and a storage medium provided in the embodiments of the present application, in which when a central processing unit converts a color space of a picture, if picture parameters of the picture meet preset parameters, the conversion of the color space of the picture is stopped and the picture is directly displayed, so as to release resources of the central processing unit and reduce power consumption. The specific picture processing method is described in detail in the following embodiments.
An application environment suitable for the image processing 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 Canvas (Canvas) is used to perform color space conversion processing on pictures in an interface (e.g., activity), and a picture to be color space converted is first processed by a graphics processing function library (Skia) to obtain a corresponding bitmap, and then color space conversion is performed based on the bitmap. In the color space conversion process, the color space conversion is performed based on a hardware acceleration drawing module (HWUI) or a graphics processing function library (Skia), and then the color space 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 of the mobile terminal.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a picture processing method according to an embodiment of the present application. The image processing method is used for stopping converting the color space of the image and directly displaying the image when the image parameter of the image meets the preset parameter when the central processing unit converts the color space of the image, so that the resources of the central processing unit are released, and the power consumption is reduced. In a specific embodiment, the picture processing method is applied to the picture processing apparatus 200 shown in fig. 9 and the mobile terminal 100 (fig. 10) configured with the picture processing apparatus 200. 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 explained in detail with respect to the flow shown in fig. 2, the mobile terminal includes a central processing unit, and the image processing method may specifically include the following steps:
step S101: and when the mobile terminal is detected to convert the color space of the picture through the central processing unit, obtaining picture parameters of the picture.
In this embodiment, the mobile terminal may convert the color space of the picture through a Central Processing Unit (CPU), or may convert the color space of the picture through a Graphics Processing Unit (GPU). The mobile terminal can select one element from the central processing unit and the graphic processor according to preset selection logic to convert the color space of the picture. For example, the selection logic may include temporal selection logic to select at a first time to convert the color space of the picture by the central processor and to select at a second time different from the first time to convert the color space of the picture by the graphics processor. For another example, the selection logic may include conditional selection logic, that is, a picture with a requirement on instantaneity higher than a preset requirement is selected and converted into a color space of the picture through a graphics processor, and a picture with a requirement on instantaneity lower than a preset requirement is selected and converted into a color space of the picture through a central processing unit. Of course, in some embodiments, the central processing unit or the graphics processing unit may also be selected according to other selection logics, which is not limited herein.
As an implementation manner, when the mobile terminal loads a picture on a display screen or a user interface of an application program, if the color space of the picture is not consistent with the color space of the display screen or the color space of the user interface of the application program, the color space of the picture may be converted, so that the color space of the picture is converted to be consistent with the color space of the display screen or consistent with the color space of the user interface of the application program, so as to improve the display effect of the picture.
Further, when the mobile terminal converts the color space of the picture, it can be detected whether the mobile terminal converts the color space of the picture through the central processing unit. In some embodiments, the picture parameters of the picture may include a picture size of the picture, a picture resolution of the picture, picture pixels of the picture, a picture format of the picture, and the like, which are not limited herein. In one embodiment, EXIF (exchangeable image file) information of a picture may be directly read, and parameter information of the picture may be read from the EXIF information. The EXIF information is a format specifically set for digital photographs. Such a format can be used to record attribute information of a digital photo, such as a brand and a model of a camera, a photographing time of the photo, a diaphragm size set at the time of photographing, a shutter speed, ISO information, a color space, a picture size, a picture resolution, a picture format, a picture pixel, and the like, but is not limited thereto.
Step S102: and judging whether the picture parameters of the picture meet preset parameters or not, wherein the preset parameters are used for reflecting parameters that the power consumption caused by converting the color space of the picture through the central processing unit is higher than the preset power consumption.
In some embodiments, the mobile terminal presets and stores preset parameters, and the preset parameters are used as a basis for determining picture parameters of a picture, so that after the mobile terminal acquires the picture parameters of the picture, the picture parameters of the picture can be compared with the preset parameters to determine whether the picture parameters of the picture meet the preset parameters. In this embodiment, the preset parameter may be a parameter that reflects that power consumption caused by the conversion of the color space of the picture by the central processing unit is higher than the preset power consumption, that is, it is determined whether the picture parameter of the picture satisfies the preset parameter, that is, it is determined whether power consumption caused by the conversion of the color space of the picture by the mobile terminal through the central processing unit is higher than the preset power consumption, it can be understood that when the determination result represents that the picture parameter of the picture satisfies the preset parameter, that is, power consumption caused by the conversion of the color space of the picture by the mobile terminal through the central processing unit is higher than the preset power consumption, resource shortage of the central processing unit may be caused, and a display jam of the mobile terminal may be caused; when the picture parameter of the picture represented by the judgment result does not meet the preset parameter, namely the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is not higher than the preset power consumption, the problem that resources of the central processing unit are short and then a display of the mobile terminal is stuck is avoided.
When the picture parameter of the picture is the picture size, the preset parameter can be the preset size, whether the picture parameter of the picture meets the preset parameter is judged, and whether the picture size of the picture is larger than the preset size is judged; when the picture parameter of the picture is the picture resolution, the preset parameter can be the preset resolution, whether the picture parameter of the picture meets the preset parameter is judged, and whether the picture resolution of the picture is greater than the preset resolution is judged; when the picture parameter of the picture is in the picture format, the preset parameter may be in the preset format, and whether the picture parameter of the picture meets the preset parameter or not is determined, and whether the picture format of the picture meets the preset format or not is determined, which is not limited herein.
Step S103: and when the picture parameters of the picture meet the preset parameters, stopping converting the color space of the picture and directly displaying the picture.
In some embodiments, when the picture parameter of the judgment result representation picture meets the preset parameter, that is, the judgment result representation mobile terminal converts the color space of the picture through the central processing unit to cause power consumption larger than the preset power consumption, the conversion of the color space of the picture can be stopped and the picture can be directly displayed, so that the resources of the central processing unit are released, the power consumption of the mobile terminal is reduced, and the problem of blocking is avoided.
According to the picture processing method provided by the embodiment of the application, when the mobile terminal is detected to convert the color space of the picture through the central processing unit, the picture parameter of the picture is obtained, whether the picture parameter of the picture meets the preset parameter or not is judged, the preset parameter is used for reflecting the parameter that the power consumption caused by the fact that the central processing unit converts the color space of the picture is higher than the preset power consumption, when the picture parameter of the picture meets the preset parameter, the conversion of the color space of the picture is stopped and the picture is directly displayed, therefore, when the central processing unit converts the color space of the picture, and if the picture parameter of the picture meets the preset parameter, the conversion of the color space of the picture is stopped and the picture is directly displayed, so that the resources of the central processing unit are released, and the power consumption is reduced.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a picture processing 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. 3, where the image processing method may specifically include the following steps:
step S201: and when the mobile terminal is detected to convert the color space of the picture through the central processing unit, obtaining the picture size of the picture.
In this embodiment, the picture parameter is a picture size, where the picture size is size data describing one picture, and is generally described as "picture length 1920 and picture width 1080". The "length and width" of a digital picture is not a length unit in a physical sense, but the number of pixels included in two dimensions, namely, the "horizontal" and "vertical" dimensions of the picture. For example, a 1920 × 1080 picture is composed of 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction (2073600 pixels in total). Correspondingly, when the mobile terminal is detected to convert the color space of the picture through the central processing unit, the mobile terminal can acquire the picture size of the picture. For example, the mobile terminal may read a picture size of a picture from the EXIF information, which is not limited herein.
Step S202: and judging whether the picture size of the picture is larger than a preset size.
In some embodiments, the mobile terminal is preset and stores a preset size, and the preset size is used as a basis for determining the picture size of the picture, so that after the mobile terminal acquires the picture size of the picture, the picture size of the picture can be compared with the preset size to determine whether the picture size of the picture is larger than the preset size. When the picture size of the picture is larger than the preset size, the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is higher than the preset power consumption, and the picture parameter of the picture is determined to meet the preset parameter; when the picture size of the picture is not larger than the preset size, the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is not larger than the preset power consumption, and the picture parameter of the picture is determined not to meet the preset parameter.
Step S203: and when the picture size of the picture is larger than the preset size, determining that the picture parameter of the picture meets the preset parameter, wherein the preset parameter is used for reflecting that the power consumption caused by converting the color space of the picture through the central processing unit is higher than the parameter of the preset power consumption.
Step S204: and when the picture parameters of the picture meet the preset parameters, stopping converting the color space of the picture and directly displaying the picture.
For detailed description of step S204, please refer to step S103, which is not described herein again.
In another embodiment of the present application, when it is detected that the mobile terminal converts the color space of the picture through the central processing unit, obtaining a picture size of the picture, determining whether the picture size of the picture is larger than a preset size, when the picture size of the picture is larger than the preset size, determining that a picture parameter of the picture meets a preset parameter, where the preset parameter is used to reflect a parameter that power consumption caused by converting the color space of the picture through the central processing unit is higher than the preset power consumption, and when the picture parameter meets the preset parameter, stopping converting the color space of the picture and directly displaying the picture. Compared with the picture processing method shown in fig. 2, the embodiment also judges whether the picture parameters meet the preset parameters according to the picture size of the picture, so as to improve the accuracy of picture parameter judgment.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a picture processing method according to still 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 processing method may specifically include the following steps:
step S301: and when the mobile terminal is detected to convert the color space of the picture through the central processing unit, obtaining the picture resolution of the picture.
In this embodiment, the picture parameter is a picture resolution, where the picture resolution refers to the number of pixels in a unit area, i.e., a pixel density, and the unit is dpi (dots per inch). The larger the total number of pixels of the picture is, the larger the picture breadth size is, but the higher the resolution is not necessarily; what really determines the resolution of a picture is the number of pixels in a unit area of the picture, i.e., the pixel density of the picture. Correspondingly, when the mobile terminal is detected to convert the color space of the picture through the central processing unit, the mobile terminal can acquire the picture resolution of the picture. For example, the mobile terminal may read the picture resolution of the picture from the EXIF information, which is not limited herein.
Step S302: and judging whether the picture resolution of the picture is greater than a preset resolution or not.
In some embodiments, the mobile terminal presets and stores a preset resolution, where the preset resolution is used as a criterion for determining a picture resolution of the picture, and therefore, after the mobile terminal obtains the picture resolution of the picture, the mobile terminal may compare the picture resolution of the picture with the preset resolution to determine whether the picture resolution of the picture is greater than the preset resolution. When the picture resolution of the picture is greater than the preset resolution, the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is considered to be greater than the preset power consumption, and the picture parameter of the picture is determined to meet the preset parameter; when the picture resolution of the picture is not greater than the preset resolution, the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is not greater than the preset power consumption, and the picture parameter of the picture is determined not to meet the preset parameter.
Step S303: when the picture resolution of the picture is greater than the preset resolution, determining that the picture parameters of the picture meet the preset parameters, wherein the preset parameters are used for reflecting that the power consumption caused by the conversion of the color space of the picture by the central processing unit is higher than the parameters of the preset power consumption.
Step S304: and when the picture parameters of the picture meet the preset parameters, stopping converting the color space of the picture and directly displaying the picture.
For detailed description of step S304, please refer to step S103, which is not described herein.
In another embodiment of the present application, when it is detected that the mobile terminal converts the color space of the picture through the central processing unit, obtaining a picture resolution of the picture, determining whether the picture resolution of the picture is greater than a preset resolution, when the picture resolution of the picture is greater than the preset resolution, determining that a picture parameter of the picture meets a preset parameter, where the preset parameter is used to reflect a parameter that power consumption caused by converting the color space of the picture through the central processing unit is higher than the preset power consumption, and when the picture parameter meets the preset parameter, stopping converting the color space of the picture and directly displaying the picture. Compared with the picture processing method shown in fig. 2, in the embodiment, whether the picture parameter meets the preset parameter is further determined according to the picture resolution of the picture, so that the accuracy of picture parameter determination is improved.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a picture processing 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. 5, where the image processing method may specifically include the following steps:
step S401: and when the mobile terminal is detected to convert the color space of the picture through the central processing unit, obtaining the picture format of the picture.
In this embodiment, the picture parameter is a picture format. The picture format is a format for storing pictures in a computer, and common storage formats include bmp, jpg, png, tif, gif, pcx, tga, exif, fpx, svg, psd, cdr, pcd, dxf, ufo, eps, ai, raw, wmf, webp and the like. Correspondingly, when the mobile terminal is detected to convert the color space of the picture through the central processing unit, the mobile terminal can acquire the picture format of the picture. For example, the mobile terminal may read a picture format of a picture from the EXIF information, which is not limited herein.
Step S402: and judging whether the picture format of the picture meets a preset format or not.
In some embodiments, the mobile terminal presets and stores a preset format, and the preset format is used as a basis for determining the picture format of the picture, so that after the picture format of the picture is acquired, the mobile terminal can compare the picture size of the picture with the preset format to determine whether the picture format of the picture meets the preset format. When the picture format of the picture meets the preset format, the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is considered to be larger than the preset power consumption, and the picture parameter of the picture is determined to meet the preset parameter; when the picture format of the picture does not meet the preset format, the power consumption caused by the fact that the mobile terminal converts the color space of the picture through the central processing unit is not larger than the preset power consumption, and the picture parameter of the picture is determined not to meet the preset parameter.
The preset format may be used to represent a format in which the size of the picture is larger than a preset size. For example, the preset format may include: bmp, psd, hdcpg, etc., without limitation.
Step S403: and when the picture format of the picture meets the preset format, determining that the picture parameters of the picture meet the preset parameters, wherein the preset parameters are used for reflecting that the power consumption caused by converting the color space of the picture through the central processing unit is higher than the parameters of the preset power consumption.
Step S404: and when the picture parameters of the picture meet the preset parameters, stopping converting the color space of the picture and directly displaying the picture.
For detailed description of step S404, please refer to step S103, which is not described herein.
In another embodiment of the present application, when it is detected that the mobile terminal converts the color space of the picture through the central processing unit, the picture format of the picture is obtained, whether the picture format of the picture meets the preset format is determined, when the picture format of the picture meets the preset format, it is determined that the picture parameter of the picture meets the preset parameter, the preset parameter is used for reflecting that the power consumption caused by converting the color space of the picture through the central processing unit is higher than the parameter of the preset power consumption, and when the picture parameter meets the preset parameter, the conversion of the color space of the picture is stopped and the picture is directly displayed. Compared with the picture processing method shown in fig. 2, the embodiment also judges whether the picture parameters meet the preset parameters according to the picture format of the picture, so as to improve the accuracy of picture parameter judgment.
Referring to fig. 6, fig. 6 is a schematic flowchart illustrating a picture processing method according to yet another embodiment of the present application. The method is applied to the mobile terminal, the mobile terminal includes a display screen, and the following will explain in detail with respect to the flow shown in fig. 6, where the image processing method may specifically include the following steps:
step S501: and when the mobile terminal is detected to convert the color space of the picture through the central processing unit, detecting the residual resources of the central processing unit.
In some embodiments, the conversion of the color space of the picture may occupy more resources of the central processing unit, and therefore, if the color space of the larger picture is converted under the condition that the remaining resources of the central processing unit are less, the problems of screen flashing and screen jamming may be caused. The detected remaining resource of the central processing unit may be a remaining resource value, or may be a remaining resource proportion, which is not limited herein.
Step S502: and judging whether the residual resources are smaller than preset resources.
In some embodiments, the mobile terminal presets and stores a preset resource, where the preset resource is used as a criterion for determining the remaining resource of the central processing unit, and therefore, after acquiring the remaining resource of the central processing unit, the mobile terminal may compare the remaining resource of the central processing unit with the preset resource to determine whether the remaining resource of the central processing unit is smaller than the preset resource. It can be understood that when the determination result indicates that the remaining resources are less than the preset resources, the characterization may cause a stuck problem if the central processing unit processes the larger picture, whereas when the determination result indicates that the remaining resources are not less than the preset resources, the characterization may not cause a stuck problem if the central processing unit processes the larger picture.
Step S503: and when the residual resources are smaller than the preset resources, acquiring picture parameters of the picture.
Step S504: and judging whether the picture parameters of the picture meet preset parameters or not, wherein the preset parameters are used for reflecting parameters that the power consumption caused by converting the color space of the picture through the central processing unit is higher than the preset power consumption.
For detailed description of steps S503 to S504, please refer to steps S101 to S102, which are not described herein again.
Step S505: and when the picture parameters of the picture meet the preset parameters, acquiring a corresponding display area of the picture on the display screen.
In some embodiments, the mobile terminal is preset with a display position and a display area corresponding to the picture on the display screen. Therefore, before the picture is displayed on the display screen, the corresponding display area of the picture on the display screen can be obtained according to the preset of the mobile terminal. For example, as shown in fig. 7, fig. 7 shows an interface schematic diagram of a mobile terminal provided in the embodiment of the present application, and in the interface schematic diagram shown in fig. 7, a display area of the picture on the display screen is a 1. For another example, as shown in fig. 8, fig. 8 shows another interface schematic diagram of the mobile terminal provided in the embodiment of the present application, and in the interface schematic diagram shown in fig. 8, a display area of the picture on the display screen is a 2. Among them, it can be known that the display area a2 is larger than the display area a 1.
Step S506: and calculating the proportion of the display area on the display screen.
By one way, the area of the display region S1 may be acquired, and the area of the display screen S2 may be acquired, then the ratio of the display region on the display screen may be S1/S2.
Step S507: and when the occupation ratio is not more than a preset occupation ratio, stopping converting the color space of the picture and directly displaying the picture.
In some embodiments, the mobile terminal presets and stores a preset proportion, which is used as a basis for determining the proportion of the display area on the display screen, so that after the proportion of the display area on the display screen is obtained, the mobile terminal can compare the proportion of the display area on the display screen with the preset proportion to determine whether the proportion of the display area on the display screen is greater than the preset proportion. In some embodiments, when the occupation ratio of the display area on the display screen is not greater than the preset occupation ratio, the user's attention may be considered not to be focused on the picture, and thus, the conversion of the color space of the picture may be stopped and the picture may be directly displayed on the corresponding display area to reduce the power consumption of the mobile terminal. For example, when the ratio of the display area on the display screen is not greater than the preset ratio, the display area corresponding to the picture on the display screen is represented to be smaller, as shown in fig. 7, and therefore, it can be considered that the attention of the user is not focused on the picture, that is, the color space of the picture is not converted to reduce the power consumption of the mobile terminal. In one embodiment, the predetermined ratio may be 1/3, 1/2, etc., and is not limited herein.
Step S508: and when the occupation ratio is switched from being not more than the preset occupation ratio to being more than the preset occupation ratio, the color space of the picture is converted again.
In some embodiments, when the display area is switched from the display area a1 shown in fig. 7 to the display area a2 shown in fig. 8 from the display area a1 not larger than the preset ratio to the display area a larger than the preset ratio, it is characterized that the user is not focused on the picture by attention, and therefore, the color space of the picture can be converted again in order to improve the display effect seen by the user.
Step S509: and when the ratio is larger than a preset ratio, continuing to convert the color space of the picture through the central processing unit.
It can be understood that, when the proportion of the display area on the display screen is greater than the preset proportion, the display area corresponding to the picture on the display screen is represented to be larger, as shown in fig. 8, so that it can be considered that the attention of the user is more focused on the picture, that is, the color space of the picture can be continuously converted to improve the display effect.
Step S510: and displaying the picture after color space conversion.
In some embodiments, after the mobile terminal performs color space conversion on the picture, the picture can be displayed to improve the display effect of the picture.
In another embodiment of the present application, when it is detected that the mobile terminal converts the color space of the picture through the central processing unit, the method detects the remaining resources of the central processing unit, determines whether the remaining resources are smaller than the predetermined resources, obtains picture parameters of the picture when the remaining resources are smaller than the predetermined resources, determines whether the picture parameters of the picture satisfy the predetermined parameters, the predetermined parameters are used to reflect that the power consumption caused by converting the color space of the picture through the central processing unit is higher than the predetermined power consumption parameters, when the picture parameters of the picture satisfy the predetermined parameters, obtains a corresponding display area of the picture on the display screen, calculates a ratio of the display area on the display screen, when the ratio is not larger than the predetermined ratio, stops converting the color space of the picture and directly displays the picture, when the ratio is switched from not larger than the predetermined ratio to being larger than the predetermined ratio, and converting the color space of the picture again, and when the ratio is greater than the preset ratio, continuing to convert the color space of the picture through the central processing unit, and displaying the picture subjected to color space conversion. Compared with the picture processing method shown in fig. 2, in the embodiment, the picture parameter of the picture is also obtained when the remaining resources of the central processing unit are smaller than the preset resources, so that the blockage caused by insufficient remaining resources of the central processing unit is reduced, and the fluency of the mobile terminal is improved. In addition, the embodiment also determines whether to convert the color space of the picture according to the ratio of the display area of the picture on the display screen, so as to improve the display effect of the picture.
