Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
With the promotion of the hardware performance of electronic equipment, more electronic equipments can be supported to carry out the higher figure of clarity
Piece is shown.However inventor has found under study for action, influences the factor of image display effect other than the information of picture itself,
There are also pictorial information and carry out the matching degree between the screen that picture is shown.
By taking color gamut space as an example.Colour gamut, that is, color gamut space is also to refer to a technology to a kind of method that color is encoded
The summation for the color that system can generate.In computer graphical processing, colour gamut is some complete subset of color.Colour gamut is empty
Between may include having sRGB colour gamut, Adobe RGB color domain or DCI-P3 colour gamut.Wherein, sRGB is the gamut standards of earliest period
One of, and obtained W3C, Exif, Intel, Pantone, Corel from industry and the branch of other many industry manufacturers
It holds.Adobe RGB color domain is mainly exactly the display improved on Blue Green, therefore can probably cover 50%CIE
1931XYZ color space.DCI-P3 is a kind of colour gamut applied to digital camera, it is that one kind with human visual experience is leading
Gamut standards, the whole colour gamuts that can show in matching film scene as far as possible.It is also not the most wide standard of colour gamut (at present most
New standard is BT.2020), but on Rec.709 standard, possess broader red/green system range.
And inventors have found that when the color gamut space of the color gamut space of picture and screen is inconsistent, directly on the screen
The inconsistent picture of display color gamut space will cause the display effect that can not be shown when picture is originally collected.For example, when corresponding to
Color gamut space wider array of picture when being shown on the narrower screen of corresponding color gamut space, shown picture can become more
Supersaturation.And when the narrower picture of corresponding color gamut space is shown on the corresponding wider array of screen of color gamut space, it shows
The picture shown can become more dim.It is not so adapted to caused display effect problem, electronic equipment in order to improve colour gamut
The color gamut space of picture can be converted, the color gamut space being adapted to be converted to picture with screen.However, invention
People further has found, needs to consume the certain process resource of electronic equipment in the conversion process of color gamut space.Therefore, it invents
People propose it is provided by the present application can flexibly based on pending color gamut conversion processing picture during color gamut conversion
Resource occupation degree complete color gamut conversion processing to determine that specifically scheduling GPU still dispatches CPU, and then improve colour gamut
The flexibility of process resource scheduling in conversion process.
The environment first run below to the embodiment of the present application is introduced.
As shown in Figure 1, being carried out in interface (such as activity) in painting canvas (Canvas) in the embodiment of the present application
The color gamut conversion of picture is handled, and the processing that the picture of Yao Jinhang color gamut conversion can first pass through function handling graph library (Skia) obtains
Corresponding bitmap is then based on bitmap and carries out color gamut conversion.It may be turned by colour gamut is carried out based on CPU during color gamut conversion
Change processing, it is also possible to which color gamut conversion processing is carried out based on GPU.In addition it is also possible to which partial region, which is based on CPU, carries out colour gamut
Conversion process, and other part region is based on GPU and carries out color gamut conversion processing.
Teachings herein is introduced below in conjunction with specific embodiment.
Referring to Fig. 2, a kind of color gamut conversion processing method provided by the present application, is applied to electronic equipment, the method packet
It includes:
Step S110: the picture of pending color gamut conversion processing is obtained.
Wherein, the picture of pending color gamut conversion processing is picture to be shown and needing to carry out color gamut conversion.
Wherein, as a kind of mode, picture to be shown is the content of also non-exhibiting pictures itself, and chosen by user
Picture.For example, as shown in figure 3, show there is the icons of multiple pictures in interface 99, when detecting that wherein some icon is by user
After choosing, it is determined that picture corresponding to the selected icon is picture to be shown.As a kind of mode, when detecting it
In some icon be user's touch-control after, determine that this is chosen by the icon of touch-control by user.Alternatively mode, when detecting
Pressing operation in display diagram target interface is acted on, and the pressing operation is being kept to move a certain distance in divided region
When having icon, using the corresponding picture of icon in the region as picture to be shown.For example, as shown in figure 4, in Fig. 4,
It first detects that user acts on the pressing operation of touch point 98, and pressing is kept to be continuously moved to touch point 97, then in figure
4 icons in the region that dotted line frame is surrounded are exactly selected icon, further figure corresponding to selected icon
Piece is picture to be shown.
Alternatively mode, picture to be shown be illustrate preview image, and chosen by user amplify with into
The picture of row full screen display.
It, can be further by the color gamut space and screen of picture to be shown after getting the color gamut space of picture to be shown
Color gamut space be compared, if the color gamut space of the color gamut space of picture to be shown and screen is inconsistent, then should be to aobvious
Diagram piece can be confirmed as the picture of pending color gamut conversion processing.
Wherein, and for electronic equipment can there are ways to obtain the color gamut space of picture to be shown.
As a kind of mode, EXIF (Exchangeable Image File) information of picture can be read directly, from
The color gamut space of picture is read out in EXIF information.Wherein, EXIF information is a kind of format exclusively for digital photos setting.This
The format of sample can be used to record the attribute information of digital photos, such as the brand and model of camera, the shooting time of photograph, shooting
When the information and color gamut space etc. such as set aperture size, shutter speed, ISO.
Alternatively mode can be directly based upon the ICC profile file of picture to get the colour gamut of picture
Space.
As yet another approach, electronic equipment can also generate one when acquiring image, while generating EXIF information
Image information is with file.The information that extended meeting is modified because of editing again after storage picture in this document, for example, picture
Color gamut space or saturation degree etc..Then it is globally unique to obtain one the information of picture collected to be done Hash operation
The identifier is inserted into the image information in file by identifier.And the part image information is with file synchronization to cloud,
So when showing the picture of aforementioned acquisition on other electronic equipments, even if the picture is edited again and causes EXIF
(for example, causing color gamut space to become because color is edited when information in information has not been information when being initially collected
Change), other electronic equipments, which can get image information by cloud and find picture with file, to be initially collected
When information (for example, color gamut space), so as to preferably restore picture it is collected when display effect.
Furthermore as a kind of mode, a file can be configured in the system of electronic equipment for storing the current of screen
Color gamut space.So in this manner, electronic equipment can get the color of the screen by way of reading this document
Domain space.
So based on foregoing manner in the application journey where the color gamut space and picture to be shown for getting picture to be shown
The color gamut space of sequence is inconsistent, or gets the color gamut space of picture to be shown and the inconsistent situation of color gamut space of screen
Under, then the picture to be shown is the picture of pending color gamut conversion processing.For example, if the color gamut space of picture to be shown is sRGB
Colour gamut (for example, inquiring color gamut space described in the ICC profile file of picture is sRGB colour gamut), and the figure to be shown
The color gamut space of piece owning application be Adobe RGB color domain (wherein it is possible to by the configuration file of inquiry application come
Inquire the color gamut space for the program that is applied), in the case where sRGB colour gamut and Adobe RGB color domain are different color gamut spaces,
It can so identify that the picture to be shown is the picture of pending color gamut conversion processing.Again alternatively, if picture to be shown
Color gamut space is sRGB colour gamut (for example, passing through the color gamut space of adjoint file acquisition above-mentioned to picture), and the colour gamut of screen
Space is DCI-P3 colour gamut, in the case where sRGB colour gamut is different from DCI-P3 colour gamut, then can identify that this is to be shown
Picture is the picture of pending color gamut conversion processing.
Step S120: the resource occupation degree that the picture carries out color gamut conversion is detected.
It is understood that the process that electronic equipment carries out color gamut conversion processing can regard the process of data operation as.
It so also means that and needs to consume process resource to carry out data operation, and need the data of operation more, also mean that
The process resource of required consumption is also more.So for the ease of the allotment of subsequent process resource, electronic equipment can be examined first
The picture for surveying pending color gamut conversion completes color gamut conversion and needs to consume how many process resources, that is, the mistake in color gamut conversion
The journey of occupancy degree in to(for) resource be how.
As a kind of mode, the step of detection picture carries out the resource occupation degree of color gamut conversion, includes:
The characteristic parameter for characterizing the resource occupation degree for carrying out color gamut conversion is obtained, the characteristic parameter is characterization institute
The parameter of the resource occupation degree of picture is stated, the value of the characteristic parameter is bigger, and the characterized resource occupation degree is bigger,
If the characteristic parameter is greater than specified threshold, determine that the resource occupation degree meets first object condition；If the feature ginseng
Number is not more than specified threshold, determines that the resource occupation degree meets the second goal condition.
Wherein, optionally, the characteristic parameter is the size of the picture, and the specified threshold is specified size threshold value.
It should be noted that characterization of size be the practical display area occupied of picture size, to a certain extent, size is bigger
The occupied display area of picture it is also bigger, it is also possible to mean that content included by picture is more, then needing
The part for carrying out color gamut conversion is more.It is so used as a kind of mode, colour gamut can be carried out to various sizes of picture in advance and turned
The resource occupation degree for changing processing is calculated, and the mapping relations of resource occupation degree and dimension of picture are established, so that electronics is set
It is standby after the picture for getting pending color gamut conversion processing, can by directly by searching for mapping relations in a manner of get pair
The resource occupation degree answered.
Optionally, the characteristic parameter can also be the resolution ratio of the picture, and corresponding, the specified threshold is specified
Resolution threshold.It is understood that the resolution ratio of picture the high so to also imply that picture is more clear, then entrained by picture
Resource occupation degree it is also bigger, and then during carrying out color gamut conversion processing consumed process resource also more
It is more.
Furthermore it should be noted that even corresponding size is identical, then also can because of picture compression ratio or point
Resolution causes picture, and occupied process resource can different from during processing.So it is used as a kind of mode, the feature
Parameter can include the size of picture and the resolution ratio of picture simultaneously, then in this manner, electronic equipment can be preparatory
The tables of data of the mapping relations between the size, resolution ratio and resource occupation degree of a picture is established, and then is being got
After the picture of pending color gamut conversion, while size and resolution ratio are inquired to get needed for corresponding progress color gamut conversion
The resource occupation degree wanted.Then corresponding resource occupation degree is occupied degree with target resource to be compared, if more than mesh
Mark resource occupation degree, which then characterizes, needs to carry out GPU progress color gamut conversion operation.
For example, it is as shown in the table:
| Size | Resolution ratio | Resource occupation degree |
| a*b | Aaa*bbb | M% |
| c*d | Ccc*ddd | N% |
In upper table, this field of size characterizes the size of picture, and this field of resolution ratio characterizes the resolution ratio of picture,
And this field of resource occupation degree characterization picture carries out the resource occupation degree consumed required for color gamut conversion.Wherein, as one kind
Mode can characterize resource occupation degree by the utilization rate of CPU.So in this manner, CPU usage gets over Gao Suobiao
The resource occupation degree of sign is higher.For example, if the size for recognizing the picture of pending color gamut conversion processing is a*b, identification
It is Aaa*bbb to its resolution ratio, then corresponding can get corresponding resource occupation degree is m%, then and then can incites somebody to action
M% occupies degree with target resource and is compared, and is to carry out color gamut conversion with CPU or GPU with determination.
Wherein, it should be noted that target resource therein occupies degree and can determine in several ways.
As a kind of mode, target resource can be set by preconfigured mode and occupies degree.Furthermore as another
A kind of outer mode dynamically can be configured dynamically according to the surplus of the current process resource of electronic equipment.It is optional
, degree is occupied using the surplus of the current process resource of electronic equipment as target resource.For example, with the utilization rate of CPU
For, if the utilization rate of current CPU is 95%, then the surplus of the current process resource of corresponding electronic equipment is 5%
CPU usage.So in this manner, degree can be occupied using 5% CPU usage as target resource.So
When CPU usage of the resource occupation degree lower than 5% for the picture progress color gamut conversion for getting pending color gamut conversion, then
Color gamut conversion processing is just carried out by CPU, and then reduces and calls overhead used in GPU, can also not influence electronics
In the case where other performances of equipment, the color gamut conversion processing of picture is just completed.And if the picture for carrying out color gamut conversion carries out color
The resource occupation degree of domain conversion is not less than 5% CPU usage, then color gamut conversion processing will be completed based on GPU.
Furthermore, it should be noted that in a kind of relevant mode, electronic equipment is in order to guarantee to have sufficient CPU to use
Resource carries out data processing, can configure a buffering section, and makes the utilization rate of CPU that can't really reach 100%.
So in this mode, target resource occupies degree and subtracts corresponding buffering section institute for the process resource of electronic equipment surplus
Corresponding process resource.For example, if the CPU usage that the caching section of configuration is 3%, then in this manner, if electronics
The CPU usage that the surplus of the current process resource of equipment is 5%, then it is 5% that corresponding target resource, which occupies degree,
CPU usage subtracts 3% CPU usage, is 2% CPU usage.
Step S130: if the resource occupation degree meets first object condition, the color of the picture is completed based on GPU
Domain conversion.
Step S140: if the resource occupation degree meets the second goal condition, the color of the picture is completed based on CPU
Domain conversion.
It should be noted that the goal condition in the present embodiment characterizes the resource occupation journey of the picture of pending color gamut conversion
The size of degree, then characterizing the figure of pending color gamut conversion processing if the resource occupation degree meets first object condition
The resource occupation degree of piece is relatively large, then avoiding excessively occupying CPU's for offloading the CPU to a certain extent
Process resource in turn results in electronic equipment Caton, the picture of pending color gamut conversion can be transferred to GPU to complete the picture
Color gamut conversion.
It is corresponding, then being characterized at pending color gamut conversion if the resource occupation degree meets the second goal condition
The resource occupation degree of the picture of reason is relatively small, because even being calling GPU is also to need CPU to be responsible for sending to GPU
Control instruction, the process resource that can still consume certain CPU is also meaned that, then in the processing of pending color gamut conversion
In the case that the resource occupation degree of picture is relatively small, so that it may directly complete the picture of pending color gamut conversion by CPU
Color gamut conversion, avoid because call GPU consumed by cpu resource.
It should be noted that being unsatisfactory for first object condition in the embodiment of the present application, it can be understood as meet the second mesh
Mark condition.
A kind of color gamut conversion processing method provided by the present application can obtain the picture of pending color gamut conversion processing first,
Then the resource occupation degree that the picture carries out color gamut conversion is detected, if the resource occupation degree meets first object item
Part completes the color gamut conversion of the picture based on GPU, if the resource occupation degree meets the second goal condition, is based on CPU
To complete the color gamut conversion of the picture.By this method can flexibly based on pending color gamut conversion processing picture
Resource occupation degree during color gamut conversion completes color gamut conversion processing to determine that specifically scheduling GPU still dispatches CPU,
And then improve the flexibility of the process resource scheduling during color gamut conversion.
Referring to Fig. 5, a kind of color gamut conversion processing method provided by the present application, is applied to electronic equipment, the method packet
It includes:
Step S210: the picture of pending color gamut conversion processing is obtained.
Step S220: the resource occupation degree that the picture carries out color gamut conversion is detected.
Step S230: it if the resource occupation degree meets first object condition, identifies at the pending color gamut conversion
Whether the picture of reason is stored with the solid color regions demarcated in advance.
It should be noted that CPU and GPU is during carrying out data processing, it is each to have respective advantage by oneself.Wherein, CPU
Processing is more good at not repeat and complicated operation, and GPU is good at the high movement of processing multiplicity.Inventor has found under study for action,
If carrying out color gamut conversion processing for solid color regions, that is constantly to carry out identical color gamut conversion processing operation in fact.Example
Such as, if the color value (rgb value) of each pixel of picture is identical, then it converts the corresponding colour gamut of some pixel really
After space obtains ginseng number, it is all repeated movement in fact that the standard of the color gamut space of other pixels, which is changed,.So for solid color area
The color gamut conversion in domain is more suitable for giving GPU to be handled.
Furthermore the identification of the color value of the pixel of picture is needed to consume the regular hour in fact, then in order to be promoted
The efficiency of identification can carry out the identification of the color value of the pixel of picture in advance.For example, can picture be downloaded to it is local or
Person is when collected, with regard to carrying out the marking operation of solid color regions.It further, can after the marking operation for carrying out solid color regions
It is the coordinate system that (0,0) is put further to establish some fixed point pixel with picture, and then establishes the mapping of coordinate and pixel
Relationship hands over the content of those ranges so that electronic equipment can identify to mark the range of solid color regions by coordinate
Color gamut conversion processing is carried out to CPU, and gives which content to GPU to carry out color gamut conversion processing.
So in this manner, the identical number of the color value of the pixel recognized is more than that the region of target number is pure
Color region.Optionally, the picture that pending solid color regions identify can be divided into multiple subregions by electronic equipment in advance, then
Whether there is color value identical in identification each subregion and quantity is more than the pixel of target number, if having just directly has this
Color value is identical and quantity be more than target number pixel subregion as solid color regions.For example, as shown in fig. 6, to
The picture for carrying out solid color regions identification is divided for 6 regions, respectively region A, region B, region C, region D, region E with
And region F.If target number therein be 5000, then recognize region A, region B, region C, region D, region E and
What region F was corresponding in turn to includes that the quantity of the pixel of the identical number of color value is 4000,6000,8000,3000,
In the case where 2000,6000, can recognize region B, region C and region E is solid color regions.
As a kind of mode, after completing to demarcate the solid color regions of picture, the configuration text of picture can be passed through
Part stores calibrated solid color regions.For example, can establish a configuration file to store the calibrated solid color area
Domain.So, in this manner, electronic equipment can read over that take the configuration file of application program that can get all
The solid color regions of picture.
It should be noted that some application programs oneself can complete the calibration of the solid color regions for picture, but have
The configuration file of a little application programs is only capable of allowing application program itself that could access, then storing by configuration file
In this case, electronic equipment possibly can not effectively get application to the corresponding color gamut space in application program all the elements interface
The color gamut space configured at all the elements interface in program.So in such a case, it is possible to establish in the electronic device
The accessible public configuration file of third party application other than one system program.The public configuration file can be used
In storing some unclassified information, for example, the solid color regions of picture included by the developer of application program, application program,
The color gamut space etc. of the version number of application program either application program configuration.So in this manner, it answers when having detected
When being mounted with program, so that it may by the application program installed actively by the developer of the application program of oneself, included
Picture (from network download picture or call camera acquire picture) solid color regions, application program version number or
It is the color gamut space storage of application program configuration into the public configuration file.Certainly, when being stored, application can also be stored
The mark of program is so as to identifying application program belonging to the information stored in public configuration file.Wherein, this applies journey
The mark of sequence can be packet name.
It is so based on aforesaid way, when electronic equipment needs to get some application program, so that it may pass through inquiry
Public configuration file above-mentioned realizes the solid color regions for getting picture included by the application program, even and if then realizing and existing
It is still available into application program in the case that electronic equipment can not be directly obtained the configuration file of application program itself
The solid color regions of all pictures.
It should be noted that the information stored in aforementioned public configuration file is not limited only to what aforementioned exemplary was pointed out
Developer, version number either color gamut space of application program configuration of application program of application program etc., can also include more
More information.For example, it is also possible to include the authority information etc. obtained required for application program.
Optionally, whether this opens that the privately owned configuration information of application program is written in aforementioned public configuration file is needle
For electronic equipment is global.It is also possible to for certain single application program.For this of certain single application program
In mode.A configuration interface can be set in electronic equipment, so which application program user can control for application program private
Some configuration informations are written to common configuration file, and which application program is public without privately owned configuration information to be written to
Configuration file.And common configuration file is written to by the privately owned configuration information of application program for which application program, it can
It is distinguished in a manner of by establishing list, wherein the application program in list is to need to write privately owned configuration information
Enter to aforementioned public configuration file.
For example, as shown in fig. 7, showing multiple application programs and each application program pair in interface shown in Fig. 7
The state for the control control answered.It is understood that if the state of the corresponding control control of application program is the "Off" of diagram, that
Indicate that the application program is removed or is added without in above-mentioned list, if the state of the corresponding control control of application program is figure
The "ON" shown, then indicating that the application program is added in above-mentioned list.For example, the application for entitled " application program A "
The state of program, corresponding control control is "ON", i.e., expression " application program A " this application program can be present in above-mentioned
In list.And for the application program of entitled " application program B ", the state of corresponding control control is "Off", then table
Show that " application program B " this application program is not present in list above-mentioned.It is understood that being present in answering in list
Color gamut conversion can be opened by being then characterized in program when carrying out showing interface.
Wherein it is possible to understand, electronic equipment can establish a variable, and control control is then identified using variate-value
The state of part.For example, if variate-value is 0, then it represents that application program does not need for the privately owned configuration information of application program to be written to
In aforementioned public configuration file, and if variate-value be 1, then it represents that need for the privately owned configuration information of application program to be written to aforementioned
In public configuration file.Optionally, which can store in the tables of data pre-established.In this case, electronics
Equipment can determine the need for for the privately owned configuration information of application program being written to by way of tabling look-up aforementioned public match
It sets in file.
In addition, the storage location of corresponding configuration file is phase after some application program is installed in electronic equipment
To fixed, alternatively mode, the variate-value can also be stored in the configuration file of corresponding application program.?
In this case, electronic equipment is after having detected application program installation, and detects that the application program of the installation is arranged to
After the application program of setting, the file of any txt format can be searched in the configuration folder of the application program, then at this
A variable is added in the file of the txt format found, and then using the value of the variable as variate-value above-mentioned.By this
Control control can be realized using the configuration file of application program the application in the case where not newly-increased add file in mode
State-detection answered then can be very good to distinguish some and because be the configuration file of the application program itself utilized
With the state of the corresponding control control of program.
In this case, in order to avoid the influence to configuration file script function can be with annotation as a kind of mode
Mode, variable is added in configuration file.For example, for the file of txt format, wherein with " // " or "/* " beginning
Character bit notes content.So in this case, it in the case that the variable of electronic equipment configuration is hqv, is inserted into txt file
The content entered can be " //hqv=1 ", i.e. characterization opens color gamut conversion.
It should be noted that after some application programs are updated or are reinstalled, corresponding configuration file meeting
It is modified or is replaced by alternative document.So in this case, if after detecting the application program update of setting or
After reinstalling, can first it detect whether there is also the file for the txt format chosen before, it is further if storage to detect more
It is inserted into before whether can also being read out in selected txt before after new or after reinstalling application program is corresponding
