Fig. 1 is the application environment schematic diagram of camera label allocation processing method in one embodiment.As shown in Figure 1, shouldApplication environment includes electronic equipment 102, and camera 104 is installed on electronic equipment 102, and the can also be stored in electronic equipment 102One tag set.Specifically, the first tag set of the available storage of electronic equipment 102, then traverses the first tag setIn the first label allocation, will not include preset field the first label allocation as the second label allocation.It will finally obtainSecond label allocation is stored to the second tag set.Wherein, the second label allocation is used to indicate electronic equipment 102 in application programIt initiates to obtain corresponding first label allocation when the control instruction of control camera, and is controlled according to the first label allocation of acquisitionCamera 104 executes corresponding operation.It is shot for example, controlling camera electronic equipment 102 according to the first label allocation of acquisitionObtain image 106.In one embodiment, electronic equipment 102 can be mobile phone, computer, wearable device etc., not limit hereinIt is fixed.
Fig. 2 is the flow chart of camera label allocation processing method in one embodiment.As shown in Fig. 2, the camera is matchedSetting label processing method includes step 202 to step 206.Wherein:
Step 202, the first tag set stored in electronic equipment is obtained.
It can store the first tag set in electronic equipment, at least one first label allocation stored in the first tag set(Tag).Specifically, each first label allocation can correspond to one metadata (metadata) of storage, and pass through metadataRealize the control to camera.
In one embodiment, the first tag set can store frame (framework) the layer correspondence in electronic equipmentMemory space in, cannot directly access the first tag set using (application) layer.Application program is in control cameraWhen, it needs to define a variable in application layer, then application layer is by variable transferring to frame (framework) layer, frameLayer carries out parsing to variable and finds corresponding first label allocation, then obtains the corresponding metadata of the first label allocation, andMetadata is transmitted to hardware abstraction layer (Hardware Abstract Layer, HAL), hardware abstraction layer is according to metadata realityNow to the control of camera.
If for example, application layer sets automatic for the focal modes of camera, it is assumed that " focal modes " corresponding memberData are " 10 ", and " automatic " corresponding metadata is " 1 ", then ccf layer can send a first number into hardware abstraction layerAccording to (10,1), then hardware abstraction layer sets the corresponding parameter of metadata " 10 " to (10,1) by this metadata“1”。
Step 204, the first label allocation in the first tag set is traversed, the first configuration for not including preset field is markedLabel are used as the second label allocation.
Specifically, electronic equipment can obtain the first tag set from ccf layer, and the first tag set is sent toApplication layer.There are two types of the first label allocations for including in the first tag set stored in ccf layer: one is to camera originalFirst label allocation of raw definition, one is customized first label allocations of platform vendor.In general, the application of electronic equipmentLayer can only customized first label allocation of calling platform manufacturer, controlled by customized first label allocation of platform vendorCamera.
Application layer can traverse the first label allocation in the first tag set after getting the first tag set,Whether judge in the first label allocation comprising preset field.When in the first label allocation including preset field, it is believed that this firstLabel allocation is to the primary definition of camera, the i.e. intrinsic label allocation of camera；It is pre- when not including in the first label allocationIf when field, it is believed that the first label allocation is the customized label allocation of platform vendor.
For example, all including in the first label allocation of the primary definition of Google in the framework of Camera HAL3" android " field all uses the formal definition of " Business Name+effect " in the first label allocation that platform vendor defines, whenWhen detecting in the first label allocation comprising " android " field, then it is assumed that first label allocation is primary definition；Work as inspectionWhen measuring in the first label allocation not comprising " android " field, then it is assumed that first label allocation is that platform vendor is customized's.
Step 206, the second obtained label allocation is stored to the second tag set, wherein the second label allocation is used forIndicate that electronic equipment obtains corresponding first label allocation when application program is initiated to the control instruction of camera, and according to obtainingThe the first label allocation control camera taken executes corresponding operation.
In the embodiment of the present application, the first label allocation of preset field will not included as the second label allocation, secondLabel allocation is the customized label allocation of platform vendor.Second tag set is to be stored in the corresponding memory space of application layerIn data acquisition system, the second obtained label allocation is stored in the second tag set, application layer can directly access secondThe second label allocation in tag set.
Specifically, application program is needing to control camera after the second label allocation is stored in the second tag setWhen can initiate control instruction to camera, the second configuration is then obtained directly from the second tag set according to control instructionLabel, and the second label allocation that will acquire passes to ccf layer.Since the second label allocation and the first label allocation are corresponding, therefore ccf layer directly can search the first label allocation that match according to the second label allocation for handing down, and by phaseThe corresponding metadata of matched first label allocation is sent to hardware abstraction layer, and hardware abstraction layer is further according to obtained metadata controlCamera processed executes corresponding operation.
Camera label allocation processing method provided in this embodiment, the first label stored in available electronic equipmentWhether set traverses the first label allocation in the first tag set, and judge in the first label allocation comprising preset field.It willThen the first label allocation not comprising preset field stores the second label allocation to the second label as the second label allocationIn set.Application program can obtain the second configuration mark when needing to control camera directly from the second tag setLabel, and the second label allocation by obtaining controls camera and executes corresponding operation.So there is no need to application programs everyIt all goes to define a variable when secondary control camera, then goes to search the first configuration mark by the different variables definedLabel, then control camera is gone by the first label allocation, reduce the variable for needing application program to define, reduces to variableMaintenance cost improves the efficiency of data processing.
Fig. 3 is the flow chart of camera label allocation processing method in another embodiment.As shown in figure 3, the cameraLabel allocation processing method includes step 302 to step 318.Wherein:
Step 302, when detecting the open command of camera of electronic equipment, camera is controlled according to open command and is beatenIt opens.
It is understood that generating the process of the second tag set can realize at any time.For example, in electronic equipmentIn when the free time, the first tag set is obtained to generate the second tag set；Or it when electronic equipment starting, obtainsFirst tag set generates the second tag set.
Certain electronic equipments may be limited by system, can only be allowed when camera is opened and enters preview mode,The first label allocation can be obtained, camera at this moment can be first controlled and enter preview mode, then obtains from the first tag setOne label allocation.
Step 304, preview parameter is configured to camera, and preview mode is entered according to preview state modulator camera.
In embodiment provided by the present application, can in the open command for the camera for detecting electronic equipment, according toOpen command controls camera and opens, and controls camera after opening camera and enter preview mode.Enter in cameraBefore preview mode, preview parameter can be configured to camera, preview mode is then entered according to preview state modulator camera.
Preview parameter refers to that the parameter that camera needs to be arranged when entering preview mode, such as preview parameter can be and take the photographAs head interface parameter shown on the display screen of electronic equipment after entering preview mode, be also possible to camera intoThe processing parameter etc. of the image acquired when entering preview mode, it is not limited here.
Step 306, the first tag set stored in electronic equipment is obtained.
Specifically, the first tag set stored in the corresponding memory space of ccf layer in electronic equipment is obtained, the first markLabel set can be the file that store the first label allocation, it is not limited here.It, can be with for example, in Android systemThe first label allocation is stored by " camera_metadata_tag_info.h " file in ccf layer, then " camera_Metadata_tag_info.h " file is exactly the first tag set.
Step 308, the first label allocation in the first tag set is traversed, the first configuration for not including preset field is markedLabel are used as the second label allocation.
Specifically, the application program in electronic equipment cannot directly access the corresponding memory space of ccf layer, therefore applyProgram cannot directly obtain the first label allocation from the first tag set.Electronic equipment can be from the memory space of ccf layerThe first tag set is obtained, and the second tag set is generated according to the first tag set.The second tag set generated is stored inIn the corresponding memory space of application program, application program can directly access the second tag set.
Step 310, each corresponding frequency of use of the second label allocation is counted.
It is understood that the second label allocation is to be generated according to the first label allocation, therefore application program is controllingWhen camera, corresponding first label allocation directly can be searched according to the second label allocation, and mark according to the first configurationLabel execute corresponding operation to control camera.
Before generating the second tag set, each corresponding frequency of use of the second label allocation can be counted.SecondThe corresponding frequency of use of label allocation is to correspond to the frequency of use namely electronics of the first label allocation of the second label allocationEquipment searches the frequency of the first label allocation.
Specifically, each second label allocation corresponding access times in statistical time range can be counted, according to statisticsAccess times and the duration of statistical time range calculate frequency of use.For example, statistics obtains the corresponding frequency of use of label allocation A10 times/day, 4 times/day of the corresponding frequency of use of label allocation B, 21 times/day of the corresponding frequency of use of label allocation C.
Step 312, the second label allocation is ranked up according to frequency of use, and the second label allocation after sequence is depositedIt stores up to the second tag set.
After statistics obtains each second label allocation, the second label allocation can be arranged according to frequency of useThen sequence stores the second label allocation into the second tag set according to sequence.The second label allocation is stored in this wayIt, can be according to frequency of use when application program searches the second label allocation in the second tag set in two tag setsIt is searched, improves search efficiency.
In one embodiment, descending sort can be carried out to the second label allocation according to frequency of use, it can also basisFrequency of use carries out ascending sort to the second label allocation, it is not limited here.The second tag set generated is stored in applicationIn the corresponding memory space of layer, since the first label allocation in the first tag set may have newly-increased, replacement, deletion etc.Modification, therefore electronic equipment can constantly be updated the second tag set in application layer, to guarantee that application program canAccurately call the second label allocation.
Specifically, electronic equipment can periodically be updated the second tag set, since system limits, some electronics are setStandby system can only allow to obtain the first tag set after opening camera, therefore electronic equipment can also opened every timeThe second tag set is updated when camera, it is without being limited thereto.
Step 314, when detecting that destination application initiates the target control instruction to camera, from the second tally setTarget control is obtained in conjunction instructs corresponding second target label allocation.
After generating the second tag set, application layer can directly access the second tag set, and from the second tag setThe second label allocation of middle acquisition.Electronic equipment can in real time monitor the working condition of application program, when detecting targetWhen application program initiates the target control instruction to camera, target control instruction pair is just obtained from the second tag setThe the second target label allocation answered.
It is understood that destination application when needing to camera operation, can initiate target control instruction.Instruction can be write in the target control instruction of initiation and initiates the contents such as time, operation data, can parse according to operation dataDestination application is specifically which operation needed to carry out camera.
For example, destination application is wanted to take pictures, then the operation data of " photo " can be carried in target control instruction,When electronic equipment detects " photo ", so that it may go to search the second label allocation corresponding with " photo " in the second tag setAs the second target label allocation, for example the second target label allocation found is " com.oppo.photo ".
Step 316, first object label allocation corresponding with the second target label allocation is obtained from the first tag set.
After getting the corresponding second target label allocation of target control instruction in the second tag set, application layer canTo pass to the second target label allocation in ccf layer, ccf layer can be searched from the first tag set to be marked with the configuration of the second targetSign the first object label allocation to match.
Step 318, the corresponding target metadata of first object label allocation is obtained, camera is controlled according to target metadataExecute corresponding operation.
Electronic equipment can pre-establish the corresponding relationship of the first label allocation and metadata, and by the first label allocation and memberData correspondence is stored in the memory space of ccf layer.After getting first object label allocation, it can according to the first configurationLabel obtains corresponding target metadata, and sends hardware abstraction layer for target metadata, then controls camera execution pairThe operation answered.
Camera label allocation processing method provided in this embodiment obtains the second configuration mark according to the first label allocationLabel, there is no need to application programs all to go to define a variable when every secondary control camera, then passes through the difference of definitionVariable go search the first label allocation, then by the first label allocation go control camera, reduce need application program determineThe variable of justice, reduces the maintenance cost to variable, improves the efficiency of data processing.The second obtained label allocation is according to makingWith being then stored into the second tag set after frequency sequence, the search efficiency of the second label allocation can be improved.
Fig. 4 is the schematic diagram for generating the second tag set in one embodiment by the first tag set.As shown in figure 4, theSeveral first label allocations in one tag set, the first label allocation can be with primary label (such as: Google Tags) and manufacturersLabel (such as: Vendor Tags).First label allocation in first tag set is filtered, primary label is filtered,The second label allocation is generated according to remaining manufacturer's label, the second tag set is finally generated according to the second label allocation.
In one embodiment, as shown in figure 5, above-mentioned camera label allocation processing method can also include following stepIt is rapid:
Step 502, it when detecting that the first label allocation in the first tag set updates, obtains in the first tag setThe first label allocation updated is as update label allocation.
The second tag set is generated according to the first label allocation in the first tag set, electronic equipment is just not necessarily to applyingLayer defines a corresponding variable to each first label allocation, and the first label allocation in such first tag set is moreWhen new, without corresponding variable is updated to the first label allocation that each is updated again again, application layer is reducedMaintenance cost.
Electronic equipment, can be according to update when detecting that the first label allocation in the first tag set updatesFirst label allocation is updated the second tag set.The update of first label allocation, which refers to, deletes the first label allocationThe operation such as remove, increase newly, replacing.
When detecting that the first label allocation in the first tag set updates, updated first mark can be reacquiredAll first label allocations in label set, and generated according to all first label allocations in updated first tag setFor the second label allocation of update, the second label allocation for being used for updating will be generated replace in the second tag set and deposit originallySecond label allocation of storage, to complete the update to the second tag set.It can also only obtain and be updated in first tag setFirst label allocation using the first label allocation of update as update label allocation, and is marked according to label allocation is updated to secondLabel set updates, without being limited thereto.
Step 504, the second tag set is updated according to the update label allocation for not including preset field.
In the present embodiment, using the first label allocation of update as label allocation is updated, update label allocation is gotLater, it is also desirable to be filtered to label allocation is updated, only retain the update label allocation for not including preset field, then basisThe update label allocation of reservation is updated the second tag set.
Specifically, updating in label allocation may include increasing label allocation newly, deleting label allocation, modification label allocation,If it is newly-increased label allocation, then the second configuration mark directly can be increased newly in the second tag set according to newly-increased label allocationLabel；If it is label allocation is deleted, then it can directly be found in the second tag set and delete label allocation corresponding secondLabel allocation, and the second label allocation found is deleted；It, then can be in the second tag set if it is modification label allocationIn find corresponding second label allocation of modification label allocation, and the second configuration found is marked according to modification label allocationLabel are modified.
