It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

These terms are only used to distinguish one element from another. For example, a first labelset may be referred to as a second labelset, and similarly, a second labelset may be referred to as a first labelset, without departing from the scope of the present application. Both the first labelset and the second labelset are labelsets, but they are not the same labelset.
Fig. 1 is a schematic application environment diagram of a processing method for configuring a tag for a camera in one embodiment. As shown in fig. 1, the application environment includes an electronic device 102, a camera 104 is installed on the electronic device 102, and a first tag set may be further stored in the electronic device 102. Specifically, the electronic device 102 may obtain a stored first tag set, then traverse a first configuration tag in the first tag set, and use the first configuration tag that does not include the preset field as a second configuration tag. And finally, storing the obtained second configuration label to a second label set. The second configuration tag is used to instruct the electronic device 102 to obtain the corresponding first configuration tag when the application program initiates a control instruction for controlling the camera, and control the camera 104 to execute the corresponding operation according to the obtained first configuration tag. For example, the camera electronic device 102 is controlled to capture the image 106 according to the acquired first configuration tag. In one embodiment, the electronic device 102 may be a mobile phone, a computer, a wearable device, and the like, which is not limited herein.
Fig. 2 is a flowchart of a processing method for configuring a tag for a camera in one embodiment. As shown in fig. 2, the method for processing the camera configuration label includes steps 202 to 206. Wherein:
A first set of tags may be stored in the electronic device, the first set of tags having at least one first configuration Tag (Tag) stored therein. Specifically, each first configuration tag may store one metadata (metadata) correspondingly, and control the camera is implemented through the metadata.
In one embodiment, the first set of tags may be stored in a memory space corresponding to a framework (framework) layer of the electronic device, the first set of tags not being directly accessible to an application (application) layer. When an application program controls a camera, a variable needs to be defined in an application Layer, then the application Layer transmits the variable to a framework (frame) Layer, the framework Layer analyzes the variable to find a corresponding first configuration label, then metadata corresponding to the first configuration label is obtained, the metadata is transmitted to a Hardware Abstraction Layer (HAL), and the Hardware abstraction Layer controls the camera according to the metadata.
For example, if the application layer sets the focus mode of the camera to automatic, assuming that the metadata corresponding to the "focus mode" is "10" and the metadata corresponding to the "automatic" is "1", the framework layer may send a metadata pair (10,1) to the hardware abstraction layer, and then the hardware abstraction layer sets the parameter corresponding to the metadata "10" to "1" through the metadata pair (10, 1).
Specifically, the electronic device may obtain a first set of tags from the framework layer and send the first set of tags to the application layer. There are two types of first configuration tags contained in a first set of tags stored in the framework layer: one is a first configuration tag defined natively for the camera and one is a first configuration tag customized by the platform vendor. Generally, an application layer of the electronic device can only call a first configuration tag customized by a platform manufacturer, and the camera is controlled through the first configuration tag customized by the platform manufacturer.
After the application layer obtains the first tag set, the application layer may traverse the first configuration tag in the first tag set, and determine whether the first configuration tag includes a preset field. When the first configuration tag contains a preset field, the first configuration tag is considered to be originally defined for the camera, namely the configuration tag inherent to the camera; and when the first configuration tag does not contain the preset field, the first configuration tag is considered to be a configuration tag customized by a platform manufacturer.
For example, in the architecture of Camera HAL3, the first configuration tags defined by Google native are all defined by "android" fields, the first configuration tags defined by platform vendors are all defined by "company name + role", and when the "android" fields are detected to be included in the first configuration tags, the first configuration tags are considered as native definitions; when the first configuration tag is detected to contain no 'android' field, the first configuration tag is considered to be self-defined by the platform manufacturer.
And step 206, storing the obtained second configuration tag to a second tag set, where the second configuration tag is used to instruct the electronic device to obtain a corresponding first configuration tag when the application program initiates a control instruction for the camera, and control the camera to execute a corresponding operation according to the obtained first configuration tag.
In the embodiment of the application, the first configuration tag which does not include the preset field is used as the second configuration tag, and the second configuration tag is the configuration tag defined by the platform manufacturer. The second tag set is a data set stored in a storage space corresponding to the application layer, the obtained second configuration tag is stored in the second tag set, and the application layer can directly access the second configuration tag in the second tag set.
Specifically, after the second configuration tag is stored in the second tag set, the application program may initiate a control instruction for the camera when the camera needs to be controlled, then directly acquire the second configuration tag from the second tag set according to the control instruction, and transmit the acquired second configuration tag to the framework layer. The second configuration tag and the first configuration tag are corresponding, so that the framework layer can directly search the matched first configuration tag according to the passed second configuration tag, and send the metadata corresponding to the matched first configuration tag to the hardware abstraction layer, and the hardware abstraction layer controls the camera to execute corresponding operation according to the obtained metadata.
The method for processing the camera configuration tag provided in this embodiment can obtain a first tag set stored in the electronic device, traverse a first configuration tag in the first tag set, and determine whether the first configuration tag includes a preset field. And taking the first configuration label which does not contain the preset field as a second configuration label, and then storing the second configuration label into a second label set. When the application program needs to control the camera, the application program can directly acquire the second configuration tag from the second tag set, and control the camera to execute corresponding operations through the acquired second configuration tag. Therefore, the application program is not required to define a variable when the camera is controlled each time, the first configuration label is searched through different defined variables, and the camera is controlled through the first configuration label, so that the variables required to be defined by the application program are reduced, the maintenance cost of the variables is reduced, and the data processing efficiency is improved.
Fig. 3 is a flowchart of a processing method for configuring a tag for a camera in another embodiment. As shown in fig. 3, the camera configuration label processing method includes steps 302 to 318. Wherein:
It will be appreciated that the process of generating the second set of tags can be implemented at any time. For example, when the electronic device is idle, a first set of tags is obtained to generate a second set of tags; or when the electronic equipment is started, acquiring the first label set to generate a second label set.
Some electronic devices may be limited by the system, and only when the camera is turned on and enters the preview mode, the first configuration tag may be acquired.
And step 304, configuring preview parameters for the camera, and controlling the camera to enter a preview mode according to the preview parameters.
In the embodiment provided by the application, when a starting instruction of the camera of the electronic device is detected, the camera is controlled to be opened according to the starting instruction, and the camera is controlled to enter the preview mode after the camera is started. Before the camera enters the preview mode, the preview parameters can be configured for the camera, and then the camera is controlled to enter the preview mode according to the preview parameters.
The preview parameter refers to a parameter that needs to be set when the camera enters the preview mode, for example, the preview parameter may be an interface parameter displayed on a display screen of the electronic device after the camera enters the preview mode, or may be a processing parameter of an image acquired by the camera when the camera enters the preview mode, and the like, which is not limited herein.
Specifically, a first tag set stored in a storage space corresponding to a framework layer in the electronic device is obtained, where the first tag set may be a file storing a first configuration tag, and is not limited herein. For example, in the android system, the first configuration tag may be stored by a "camera _ metadata _ tag _ info.h" file in the framework layer, and then the "camera _ metadata _ tag _ info.h" file is the first set of tags.
Specifically, an application in the electronic device cannot directly access a storage space corresponding to the framework layer, and therefore the application cannot directly obtain the first configuration tag from the first tag set. The electronic device may obtain the first set of tags from the memory space of the framework layer and generate the second set of tags from the first set of tags. The generated second labelset is stored in a storage space corresponding to the application program, and the application program can directly access the second labelset.
It can be understood that the second configuration tag is generated according to the first configuration tag, so that when the application program controls the camera, the application program can directly search the corresponding first configuration tag according to the second configuration tag, and control the camera to execute the corresponding operation according to the first configuration tag.
Before generating the second tag set, the usage frequency corresponding to each second configuration tag may be counted. The use frequency corresponding to the second configuration tag is the use frequency of the first configuration tag corresponding to the second configuration tag, that is, the frequency of the electronic device searching for the first configuration tag.
Specifically, the number of times of use of each second configuration tag in the statistical time period may be counted, and the frequency of use may be calculated according to the counted number of times of use and the duration of the statistical time period. For example, the usage frequency corresponding to the configuration tag a is counted for 10 times/day, the usage frequency corresponding to the configuration tag B is counted for 4 times/day, and the usage frequency corresponding to the configuration tag C is counted for 21 times/day.
After each second configuration tag is obtained through statistics, the second configuration tags may be sorted according to the use frequency, and then the second configuration tags are stored in the second tag set according to the sorting. Therefore, the second configuration label is stored in the second label set, and when the application program searches for the second configuration label in the second label set, the application program can search according to the use frequency, so that the searching efficiency is improved.
In an embodiment, the second configuration tags may be sorted in a descending order according to the usage frequency, or sorted in an ascending order according to the usage frequency, which is not limited herein. The generated second tag set is stored in a storage space corresponding to the application layer, and the electronic device may continuously update the second tag set in the application layer because the first configuration tag in the first tag set may be modified such as newly added, replaced, deleted, and the like, so as to ensure that the application program can accurately call the second configuration tag.
Specifically, the electronic device may update the second tag set at regular time, and due to system limitations, some systems of the electronic device may only allow the first tag set to be acquired after the camera is turned on, so the electronic device may also update the second tag set each time the camera is turned on, which is not limited to this.
After the second labelset is generated, the application layer may directly access the second labelset and obtain a second configuration label from the second labelset. The electronic device can monitor the working state of the application program in real time, and when the target application program is detected to initiate a target control instruction for the camera, a second target configuration tag corresponding to the target control instruction is obtained from the second tag set.
It will be appreciated that the target application may initiate target control instructions when it needs to operate the camera. The initiated target control instruction can be written to the instruction initiation time, the operation data and other contents, and the target application program can be analyzed according to the operation data, wherein the operation is specifically required to be performed on the camera.
For example, the target application program may carry operation data of "photo" in the target control instruction, and when the electronic device detects "photo", the electronic device may search for a second configuration tag corresponding to "photo" in the second tag set as the second target configuration tag, for example, the searched second target configuration tag is "com.
After the second target configuration tag corresponding to the target control instruction is acquired from the second tag set, the application layer may transmit the second target configuration tag to the framework layer, and the framework layer may search for the first target configuration tag matched with the second target configuration tag from the first tag set.
And step 318, acquiring target metadata corresponding to the first target configuration tag, and controlling the camera to execute corresponding operation according to the target metadata.
The electronic equipment establishes a corresponding relation between the first configuration tag and the metadata in advance, and correspondingly stores the first configuration tag and the metadata in a storage space of the framework layer. After the first target configuration tag is acquired, corresponding target metadata can be acquired according to the first configuration tag, the target metadata is sent to the hardware abstraction layer, and then the camera is controlled to execute corresponding operations.
According to the processing method for the camera configuration tag, the second configuration tag is obtained according to the first configuration tag, so that an application program is not required to define a variable when the camera is controlled each time, the first configuration tag is searched through different defined variables, and the camera is controlled through the first configuration tag, so that the variables required to be defined by the application program are reduced, the maintenance cost of the variables is reduced, and the efficiency of data processing is improved. The obtained second configuration labels are sorted according to the use frequency and then stored in the second label set, so that the searching efficiency of the second configuration labels can be improved.
FIG. 4 is a diagram that illustrates generating a second labelset from a first labelset, under an embodiment. As shown in FIG. 4, the first configuration Tags in the first tag set may be native Tags (e.g., Google Tags) and Vendor Tags (e.g., Vendor Tags). And filtering the first configuration label in the first label set, filtering the original label, generating a second configuration label according to the rest manufacturer labels, and finally generating a second label set according to the second configuration label.
In an embodiment, as shown in fig. 5, the method for processing the camera configuration tag may further include the following steps:
The second tag set is generated according to the first configuration tags in the first tag set, and the electronic device does not need to define a corresponding variable for each first configuration tag in the application layer, so that when the first configuration tags in the first tag set are updated, the corresponding variables do not need to be updated for each updated first configuration tag, and the maintenance cost of the application layer is reduced.
When detecting that the first configuration tag in the first tag set is updated, the electronic device may update the second tag set according to the updated first configuration tag. The updating of the first configuration tag refers to operations such as deleting, adding, replacing and the like of the first configuration tag.
When it is detected that the first configuration tag in the first tag set is updated, all the first configuration tags in the updated first tag set may be obtained again, a second configuration tag for updating is generated according to all the first configuration tags in the updated first tag set, and the generated second configuration tag for updating replaces the originally stored second configuration tag in the second tag set, so as to complete updating of the second tag set. It is also possible to obtain only the updated first configuration tag in the first tag set, use the updated first configuration tag as the updated configuration tag, and update the second tag set according to the updated configuration tag, but not limited thereto.
In this embodiment, the updated first configuration tag is used as the update configuration tag, and after the update configuration tag is obtained, the update configuration tag also needs to be filtered, only the update configuration tag that does not include the preset field is reserved, and then the second tag set is updated according to the reserved update configuration tag.
Specifically, the updating of the configuration tag may include adding a configuration tag, deleting a configuration tag, and modifying a configuration tag, and if the configuration tag is the added configuration tag, a second configuration tag may be directly added in the second tag set according to the added configuration tag; if the configuration label is deleted, a second configuration label corresponding to the deleted configuration label can be directly found in the second label set, and the found second configuration label is deleted; if the configuration label is modified, a second configuration label corresponding to the modified configuration label can be found in the second label set, and the found second configuration label is modified according to the modified configuration label.
In this embodiment of the application, applications installed in the electronic device may be classified in advance, where the second set of tags includes at least one classification tag set, and each class of application corresponds to one classification tag set. For example, applications in the electronic device are classified into game applications, shopping applications, video applications, camera applications, and the like, but are not limited thereto.
It will be appreciated that the application operations implemented by different application programs are different and therefore the operations implemented by the calling camera are also different. For example, the payment application program can control the camera to acquire images to realize payment verification operation, and high-precision images need to be acquired during the payment verification operation; the camera can be controlled by the photographic application program to collect images, and shooting parameters need to be adjusted when the images are collected.
The operation that different application programs need to control the camera to realize the operation may be different, so that the first configuration tags that different types of application programs need to call may be different, different second tag sets can be generated for different types of application programs according to the requirements of the application programs, and when the application programs control the camera, the application programs can search for the second configuration tags in the corresponding second tag sets, thereby improving the searching efficiency.
Specifically, the storing the obtained second configuration tag in the second tag set may specifically include: and acquiring the classification configuration labels corresponding to each type of application program from the second configuration labels, and respectively storing the acquired classification configuration labels to the corresponding classification label sets.
In an embodiment, a second tag set may be separately established for each application program, so that when the application program controls the camera, the application program may directly search for the second configuration tag from the corresponding second tag set, which is not limited herein.
In an embodiment, as shown in fig. 6, the step of storing the classification configuration tag in the classification tag set may specifically include:
step 602, obtaining the application level of each type of application program, and encrypting the classification configuration label according to the application level.
After the application layer acquires the second configuration tag, the application program in the electronic device may access the second configuration tag, which may cause a security risk. After the class configuration tag is obtained, the class configuration tag may be encrypted according to the application level of the application program.
The application level is used to indicate the importance of the application program, and the higher the application level is, the higher the security requirement of the application program is, the higher the security requirement is when controlling the camera. Therefore, the classification configuration tag can be encrypted according to the application level of the application program. Specifically, the encryption processing is performed by applying a classification configuration tag corresponding to an application program with a level higher than a level threshold.
Further, when the application level of the application program is higher than the level threshold, the encryption level can be obtained according to the application level, and the classification configuration tag corresponding to the application program is encrypted according to the encryption level. The higher the application level, the higher the security of the encryption process.
And step 604, storing the encrypted classification configuration labels to corresponding classification label sets respectively.
And after encrypting the classification configuration labels, respectively storing the encrypted classification configuration labels to corresponding classification label sets. After the application program initiates the control instruction, the camera can be controlled according to the decrypted classification configuration label after the classification configuration label is decrypted, so that the safety of controlling the camera is improved.
In an embodiment, after storing the encrypted classification configuration tag in the classification tag set, the step of controlling the camera may specifically include: when detecting that a target application program initiates a target control instruction for a camera, acquiring a target application category of the target application program, and acquiring a second target configuration label corresponding to the target control instruction from a classification label set corresponding to the target application category; acquiring a decryption password carried in the target control instruction, and decrypting the second target configuration tag according to the acquired decryption password; acquiring a first target configuration label corresponding to the decrypted second target configuration label from the first label set; and acquiring target metadata corresponding to the first target configuration tag, and controlling the camera to execute corresponding operation according to the target metadata.
It should be understood that although the steps in the flowcharts of fig. 2, 3, 5, and 6 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2, 3, 5, and 6 may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least some of the sub-steps or stages of other steps.
Fig. 7 is a flowchart illustrating steps of the method for processing the camera configuration tag. As shown in fig. 7, the steps of executing the processing method for configuring the label of the camera specifically include:

The embodiment of the application also provides the electronic equipment. The electronic device includes therein an Image Processing circuit, which may be implemented using hardware and/or software components, and may include various Processing units defining an ISP (Image Signal Processing) pipeline. FIG. 9 is a schematic diagram of an image processing circuit in one embodiment. As shown in fig. 9, for convenience of explanation, only aspects of the image processing technique related to the embodiments of the present application are shown.
As shown in fig. 9, the image processing circuit includes an ISP processor 940 and a control logic 950. The image data captured by the imaging device 910 is first processed by the ISP processor 940, and the ISP processor 940 analyzes the image data to capture image statistics that may be used to determine and/or control one or more parameters of the imaging device 910. The imaging device 910 may include a camera having one or more lenses 912 and an image sensor 914. Image sensor 914 may include an array of color filters (e.g., Bayer filters), and image sensor 914 may acquire light intensity and wavelength information captured with each imaging pixel of image sensor 914 and provide a set of raw image data that may be processed by ISP processor 940. The sensor 920 (e.g., a gyroscope) may provide parameters of the acquired image processing (e.g., anti-shake parameters) to the ISP processor 940 based on the type of interface of the sensor 920. The sensor 920 interface may utilize an SMIA (Standard Mobile Imaging Architecture) interface, other serial or parallel camera interfaces, or a combination of the above.
In addition, image sensor 914 may also send raw image data to sensor 920, sensor 920 may provide raw image data to ISP processor 940 based on the type of interface of sensor 920, or sensor 920 may store raw image data in image memory 930.
The ISP processor 940 processes the raw image data pixel by pixel in a variety of formats. For example, each image pixel may have a bit depth of 8, 10, 12, or 14 bits, and the ISP processor 940 may perform one or more image processing operations on the raw image data, collecting statistical information about the image data. Wherein the image processing operations may be performed with the same or different bit depth precision.
Upon receiving raw image data from image sensor 914 interface or from sensor 920 interface or from image memory 930, ISP processor 940 may perform one or more image processing operations, such as temporal filtering. The processed image data may be sent to image memory 930 for additional processing before being displayed. ISP processor 940 receives processed data from image memory 930 and performs image data processing on the processed data in the raw domain and in the RGB and YCbCr color spaces. The image data processed by ISP processor 940 may be output to display 970 for viewing by a user and/or further processed by a Graphics Processing Unit (GPU). Further, the output of ISP processor 940 may also be sent to image memory 930 and display 970 may read image data from image memory 930. In one embodiment, image memory 930 may be configured to implement one or more frame buffers. In addition, the output of the ISP processor 940 may be transmitted to an encoder/decoder 960 for encoding/decoding the image data. The encoded image data may be saved and decompressed before being displayed on a display 970 device. The encoder/decoder 960 may be implemented by a CPU or GPU or coprocessor.
The statistical data determined by the ISP processor 940 may be transmitted to the control logic 950 unit. For example, the statistical data may include image sensor 914 statistics such as auto-exposure, auto-white balance, auto-focus, flicker detection, black level compensation, lens 912 shading correction, and the like. The control logic 950 may include a processor and/or microcontroller that executes one or more routines (e.g., firmware) that may determine control parameters of the imaging device 910 and control parameters of the ISP processor 940 based on the received statistical data. For example, the control parameters of imaging device 910 may include sensor 920 control parameters (e.g., gain, integration time for exposure control, anti-shake parameters, etc.), camera flash control parameters, lens 912 control parameters (e.g., focal length for focusing or zooming), or a combination of these parameters. The ISP control parameters may include gain levels and color correction matrices for automatic white balance and color adjustment (e.g., during RGB processing), as well as lens 912 shading correction parameters.
