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.
At present, mobile terminal uses in daily life, and the prevalence has nearly been covered by the people, and wherein, camera module has become intelligent terminal main function point, and user's accessible mobile terminal's camera function shoots photo and video. The user can shoot photos and videos and record the moments of life, study and work through the camera function of the mobile terminal.
Meanwhile, cameras are becoming more specialized based on the evolution of shooting functions, more hardware and software function setting items are provided for users to use, for example, the users can set setting items such as High-Dynamic light rendering (HDR), beauty, intelligent recognition and the like, after clicking to shoot, the camera application can request the setting items to the camera service together, and finally picture shooting is completed.
When shooting with a mobile terminal, there are cases where multiple users use the same terminal to shoot, for example, one home may shoot with the same mobile terminal while traveling. However, in general, shooting habits of different users may be different, and when shooting is performed using a mobile terminal, different parameter values are set for setting items of a plurality of shooting parameters, and then shooting is performed. But when the user was changed and was shot, because user's shooting habit is different, will involve the user and reset the parameter value of these settings, like this, will lead to user's operation comparatively loaded down with trivial details, make user's ease of use and operability lower, and manual debugging shooting parameter again, promoted the shooting degree of difficulty, increased shooting time cost.
In view of the above problems, the inventor provides a processing method and apparatus for shooting parameters, a mobile terminal, and a storage medium, which can implement efficient switching of shooting parameters corresponding to different users when the different users use the mobile terminal to shoot, and improve convenience of user operation. The specific processing method of the shooting parameters is described in detail in the following embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a processing method of shooting parameters according to an embodiment of the present application. In a specific embodiment, the processing method of the shooting parameters is applied to the processing apparatus 400 of the shooting parameters as shown in fig. 9 and the mobile terminal 100 (fig. 10) configured with the processing apparatus 400 of the shooting parameters. The following will describe a specific flow of the embodiment by taking a mobile terminal as an example, and it is understood that the mobile terminal applied in the embodiment may be a smart phone, a tablet computer, a smart watch, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 1, the processing method of the shooting parameters may specifically include the following steps:
step S110: and displaying a shooting interface, wherein the shooting interface comprises a user selection control, and the user selection control is used for triggering the selection of shooting parameters corresponding to different user identifications.
In the embodiment of the present application, the shooting interface is an interface displayed in a shooting mode. The mobile terminal can display a shooting interface when entering a shooting mode. The shooting mode may be that the mobile terminal operates the system camera in the foreground to enter the shooting mode and displays a shooting interface of the system camera when detecting that the system camera is turned on.
The shooting mode can also be that when the mobile terminal detects that the third-party camera application is started, the third-party camera application is operated in the foreground to enter the shooting mode, and a shooting interface of the third-party system camera is displayed; the shooting mode can also be that the mobile terminal calls a camera to shoot when detecting that the application runs, and enters the shooting mode and displays a shooting interface. The starting of the camera application such as the system camera, the third-party camera application and the like can be triggered by detecting that a control (icon) of the application is touched, or certainly, by means of voice control and the like, and is not limited herein.
In some embodiments, a shooting interface displayed by the mobile terminal may include a user selection control, and the user selection control may be used to trigger selection of shooting parameters corresponding to different user identifications. The user identification is an identification representing user identity information, and different user identifications correspond to different users. For example, referring to fig. 2, the shooting interface a1 includes a user selection control a2, where the user selection control may be used to trigger the selection of the shooting parameters corresponding to different user identifiers, that is, when the user operates the user selection control through a predetermined specified operation, the selection of the shooting parameters corresponding to different user identifiers may be triggered.
In some embodiments, referring to fig. 2 again, the shooting interface may further include a shooting button A3, where the shooting button A3 is used to trigger the shooting of the image, and may also be referred to as a shutter button or a shutter button. Of course, the shooting interface may also include other content, for example, the shooting interface may also include: a preview area, a selection area of a shooting mode, an album button, a camera switching button, etc., and of course, the specific contents in the shooting interface may be limited. The preview area is used for displaying a shooting preview image; the selection area of the shooting mode is used for selecting different shooting modes, for example, shooting modes such as night scenes, videos, portrait, photos and the like can be selected; the photo album button is used for triggering the starting of the photo album; the camera switching button may be used to switch the front camera and the rear camera, and is not limited herein.
In some embodiments, shooting parameters corresponding to different user identifications can be stored in the mobile terminal. It can be understood that different user identifiers correspond to different users, and therefore, the shooting parameter corresponding to each user identifier corresponds to one user. The shooting parameters corresponding to the user identification can be preset in the camera function of the mobile terminal for the user corresponding to the user identification; the shooting parameters corresponding to the user identifier may also be shooting parameters that are configured by the mobile terminal automatically according to different user identifiers, which is not limited herein. In addition, the shooting parameters corresponding to different user identifiers may be the same or different, and are not limited herein.
Step S120: and responding to the specified operation aiming at the user selection control, and displaying the user identification list.
In the embodiment of the application, the mobile terminal may detect a touch operation in the shooting interface, where the touch operation may include a press operation, a click operation, a slide operation, and the like that are performed in the shooting interface. When the specified operation of the user selection control in the shooting interface is detected, whether the touch operation is the preset specified operation can be determined. The mobile terminal stores a designated operation in advance, and the designated operation can be used as a condition for triggering the selection of the shooting parameters corresponding to different user identifications.
In some embodiments, the user identification list may be presented when the mobile terminal detects a specified operation on the user selection control. The user identification list can comprise different user identifications, the user identifications are related to shooting parameters of different users, the user can conveniently select different user identifications by displaying different user identifications, and therefore the shooting parameters corresponding to different user identifications can be selected.
In some embodiments, when the mobile terminal detects another operation performed on the user-selected control, the mobile terminal may also respond, that is, when the mobile terminal responds to a different touch operation on the user-selected control, the mobile terminal may execute a different response according to the different touch operation. For example, the mobile terminal may also respond to other touch operations different from the specified operation, and display an edit page for editing the user identifier list, so as to perform operations such as addition and deletion of the user identifier.
In some embodiments, the designating operation may be a click operation, that is, when the mobile terminal detects a click operation on a user selection control, the mobile terminal determines the click operation as the designating operation, and displays the user identifier list in response to the designating operation. For example, referring to fig. 3 and fig. 4, clicking the user selection control a2 may trigger entering the interface shown in fig. 4, where the interface shown in fig. 4 includes a current user list a4 (corresponding to the user identifier list described above), and the current user list a4 may include user identifiers for the user to select different user identifiers, so as to select shooting parameters corresponding to different user identifiers.
Of course, the designating operation may be other touch operations, for example, a pressing operation satisfying a set pressing condition, and the like, which is not limited herein.
Step S130: and responding to the selection operation aiming at a target user identifier which is different from the current user identifier in the user identifier list, and switching the camera shooting parameters from the first shooting parameters corresponding to the current user identifier to the second shooting parameters corresponding to the target user identifier.
In the embodiment of the application, after the mobile terminal displays the user identifier list, the mobile terminal may detect an operation in the user identifier list, for example, detect a touch operation of a user identifier in the user identifier list.
In some embodiments, the operation on the user identifier in the user identifier list may include a click operation, that is, the user may complete the selection of the user identifier by performing a click operation on the user identifier that is required, and then select the shooting parameter corresponding to the user identifier. Accordingly, when the mobile terminal detects the click operation on the user identifier, it may be determined that the selection operation on the user identifier is detected.
Further, when determining that the selection operation of the user identifier is detected, the mobile terminal may use the user identifier on which the selection operation is performed as a target user identifier, and determine whether the target user identifier is the same as the current user identifier. And the current user identification is the user identification corresponding to the current shooting parameter of the mobile terminal. When the target user identification is the same as the current user identification, the current shooting parameters of the mobile terminal do not need to be adjusted; when the target user identifier is different from the current user identifier, the user is indicated to select other different user identifiers, that is, the user needs to select the shooting parameters corresponding to other user identifiers, so that the mobile terminal can switch the camera shooting parameters from the first shooting parameters corresponding to the current user identifier to the second shooting parameters corresponding to the target user identifier.
In the embodiment of the present application, the shooting parameters corresponding to each user identifier may include one or more types of shooting parameters, and the shooting parameters corresponding to different user identifiers may include the same type of shooting parameters or different types of shooting parameters. For example, the first photographing parameter and the second photographing parameter may each include: HDR, smart recognition, Beauty (FB, Face Beauty), sensitivity (ISO), zoom factor, focal length, exposure duration, exposure value, aperture size, and contrast; for another example, the first photographing parameters may include HDR, smart recognition, and FB, and the second photographing parameters may include HDR, smart recognition, and zoom magnification.
In some embodiments, the mobile terminal may read the second shooting parameter corresponding to the target user identifier and then request the camera service for the second shooting parameter, thereby completing the switching of the camera shooting parameters. When the current user of the mobile terminal is changed into another user for shooting, the other user can adjust the camera shooting parameters to the shooting parameters corresponding to the user identification after selecting the corresponding user identification through the above modes, and manual setting is not needed, so that the user operation is simplified.
After the camera shooting parameters are switched, the scene image can be acquired by using the second shooting parameters according to the detected shooting control operation, so that the shooting requirements of the user are met.
In addition, due to the original design of the current android system, parameters of a safety camera (namely, a camera started during screen locking) can be modified for shooting in order to meet the requirement of a user for quickly capturing and shooting without unlocking, and due to the global property of the camera, under a non-safety shooting scene after the mobile terminal is unlocked, camera setting items are globally modified in the safety camera, so that normal shooting is influenced after a normal user is unlocked. According to the shooting parameter processing method provided by the embodiment of the application, the shooting parameters correspond to the user identifications when the camera is used for shooting, so that the problems caused by a safety camera can be effectively avoided.
According to the shooting parameter processing method, the mobile terminal displays the shooting interface, the shooting interface comprises the user selection control used for triggering the selection of the shooting parameters corresponding to different user identifications, the appointed operation of selecting the control by the user is responded, the user identification list is displayed, then the selection operation of the target user identification different from the current user identification in the user identification list is responded, the shooting parameters of the camera are switched to the second shooting parameters corresponding to the target user identification from the first shooting parameters corresponding to the current user identification, therefore, when different users shoot by using the mobile terminal, the shooting parameters corresponding to different users can be efficiently switched, the convenience of user operation is improved, and the problem caused by a safe camera can be avoided.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a processing method of shooting parameters according to another embodiment of the present application. The processing method of the shooting parameters is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 5, and the processing method of the shooting parameters may specifically include the following steps:
step S210: and responding to the operation for triggering the starting of the camera, and acquiring the characteristic information of the current user.
In the embodiment of the application, when detecting the operation for triggering the start of the camera, the mobile terminal may respond to the operation, and when starting the camera, the mobile terminal may further determine the user identifier corresponding to the current user, and set the shooting parameters of the camera to the shooting parameters corresponding to the current user identifier, that is, the shooting parameters corresponding to the current user who shoots at present.
In some embodiments, the mobile terminal may acquire feature information of a current user, that is, a user who is currently using the mobile terminal and triggers camera activation, in response to an operation for triggering camera activation. The feature information may be biometric information of the current user, and may be, for example, a fingerprint feature, a face feature, an iris feature, and the like.
As an implementation manner, the feature information may include a face feature, and when the mobile terminal obtains the feature information of the current user, the mobile terminal may control the front-facing camera to acquire a face image of the current user, and after performing face feature extraction on the face image, obtain the face feature of the current user.
As another embodiment, the feature information may include iris information, and the mobile terminal may control the front-facing camera to acquire a face image of the current user, and extract iris features according to the face image, so as to obtain iris features of the current user.
As another embodiment, the feature information may include a fingerprint feature, and when the mobile terminal detects a touch operation of a user, the mobile terminal controls the fingerprint acquisition module to acquire fingerprint information of the current user, so that the fingerprint feature of the current user may be extracted according to the acquired fingerprint information.
Of course, the manner in which the mobile terminal specifically acquires the feature information of the current user may not be limited.
Step S220: and matching the characteristic information with the characteristic information corresponding to each user identification.
In the embodiment of the application, after the mobile terminal acquires the feature information of the current user, the acquired feature information may be matched with the feature information corresponding to each user identifier, so as to determine the user identifier corresponding to the current user. The mobile terminal may preset feature information corresponding to different user identifiers, and specifically, the mobile terminal may enter the feature information corresponding to the user identifier of the user according to input operation of the feature information of different users, and store the feature information. When the mobile terminal needs to determine the user identifier corresponding to the current user, that is, the identity of the user is determined, the obtained feature information may be matched with the feature information corresponding to each user identifier, so as to determine the identity identifier corresponding to the current user.
Step S230: and when the characteristic information of the current user is matched with the characteristic information corresponding to the appointed user identification, taking the appointed user identification as the current user identification, and setting camera shooting parameters as the shooting parameters corresponding to the appointed user identification.
In the embodiment of the application, after the mobile terminal matches the current user information with the feature information corresponding to each user identifier, the mobile terminal may determine the user identifier corresponding to the current user according to the matching result. If the mobile terminal determines that the feature information of the current user is matched with the feature information corresponding to the specified user identifier according to the matching result, the specified user identifier can be used as the current user identifier, that is, the specified user identifier is used as the user identifier corresponding to the current user. Then, the mobile terminal can set the camera shooting parameters as the shooting parameters corresponding to the specified user identification when the camera is started.
Through the mode, when the camera is started, the shooting parameters of the camera can be automatically set according to the current user identification of the current user, so that the operation of the user is further simplified, and the user experience is improved.
In addition, in still other embodiments, when determining that the identity information of the current user does not match the identity information corresponding to any user identifier, the mobile terminal may further output first prompt information, where the first prompt information is used to prompt the user whether to perform shooting with default shooting parameters; or outputting second prompt information, wherein the second prompt information is used for prompting the user to add the user identifier and the shooting parameter corresponding to the user identifier.
In some embodiments, for the shooting parameters corresponding to each user identifier, one setting scheme of the shooting parameters may be included, and multiple setting schemes of the shooting parameters may also be included. That is, for one user, it may require a plurality of setting schemes of shooting parameters, for example, different scenes require different shooting parameters, and thus different schemes may be set for shooting parameters for different scenes. When the camera shooting parameters are set as the shooting parameters corresponding to the specified user identification, the mobile terminal can determine the number of the shooting parameter sets corresponding to the specified identification, wherein one shooting set is a shooting parameter setting scheme, and the shooting parameter sets are further selected when the shooting parameter sets corresponding to the specified user identification are multiple.
As an implementation manner, when the shooting parameters corresponding to the specified user identifier include multiple shooting parameter sets, the mobile terminal may obtain an image of the current scene according to each shooting parameter set, and obtain multiple evaluation images, where each evaluation image corresponds to one shooting parameter set; scoring the image quality of each evaluation image based on a pre-trained image quality evaluation model to obtain a plurality of scores; and setting camera shooting parameters as shooting parameters in a target shooting parameter set, wherein the target shooting parameter set is a shooting parameter set corresponding to an evaluation image with a score meeting a set score condition.
The image quality evaluation model may be obtained by pre-training, and the training of the image quality evaluation model may include: the method comprises the steps of obtaining a sample image and a marked score of the sample image, and then training an initial model by using the sample image and the marked score, namely, training the initial model by using the sample image as an input and the score as an output, so as to obtain an image quality score model. The initial model may be a convolutional neural network, or may be composed of an image feature extraction model and a classifier, and the specific model may not be limited.
In some ways, the marked scores of the sample images can be derived from the scores of different users, specifically, the mobile terminal can obtain the scores of the sample images by a plurality of users to obtain the scores of the plurality of users, then calculate the mean and the variance of the scores of the plurality of users, and then calculate the difference between the mean and the variance; when the difference value is larger than the preset difference value, determining the highest score and the lowest score of the scores of the multiple users; taking the scores except the highest score and the lowest score in the plurality of user scores as target user scores; calculating the average value of the scores of the plurality of target users; determining the average value of the scores of the multiple target users as the score corresponding to the sample image; and when the difference value is not larger than the preset difference value, determining the average value of the scores of the plurality of users as the corresponding score of the sample image. The scores of the sample images are determined in the above mode, and evaluation information of different users can be referred to, so that the accuracy of the label data of the sample images is improved.
As another implementation, when the shooting parameters corresponding to the specified user identifier include multiple shooting parameter sets, the mobile terminal acquires a scene image, wherein each shooting parameter set corresponds to one shooting scene; identifying the scene image to obtain a current shooting scene; and setting camera shooting parameters as shooting parameters in a shooting parameter set corresponding to the current shooting scene based on the current shooting scene.
It is to be understood that, when multiple shooting parameter sets exist for one user identifier, the user corresponding to the user identifier may set different shooting parameter setting schemes, that is, different shooting parameter sets, for different shooting scenes. Therefore, the mobile terminal can identify the current shooting scene by using a scene identification function provided by the camera service, then determine a shooting parameter set corresponding to the current shooting scene from a plurality of shooting parameter sets, and then set the camera shooting parameters as the shooting parameters in the shooting parameter set. Therefore, the shooting parameters corresponding to different shooting scenes can be automatically set, the user operation is further simplified, and the user experience is improved.
In the embodiment of the application, when the camera is started, the mobile terminal may further determine whether a user-defined mode is started, where the user-defined mode is used to determine whether to execute the steps of obtaining the feature information of the current user and the subsequent steps in step S210, and if the user-defined mode is started, different camera shooting parameters may be set according to different user identifiers; if the user-defined mode is not started, when the camera is started, the preview interface can be directly performed, namely, normal shooting is performed, and the user selection control cannot be displayed in the shooting interface.
Step S240: and acquiring a user selection control corresponding to the specified user identification, wherein the user selection controls corresponding to different user identifications are different in style.
In the embodiment of the application, when the mobile terminal displays the shooting interface including the user selection control, the user selection control corresponding to the specified user identification can be further determined, wherein the user selection controls corresponding to different user identifications are different in style. The method and the device have the advantages that the style of the user selection control is associated with the user identification, so that the user can determine the user identification corresponding to the current camera shooting parameter through the displayed user selection control, and the user can conveniently determine whether the current camera shooting parameter is the shooting parameter corresponding to the user. For example, the user-selectable control may include different avatar designations, each of which corresponds to a user identification.
Step S250: and displaying a shooting interface, wherein the shooting interface comprises a user selection control corresponding to the specified user identification.
Step S260: and responding to the specified operation aiming at the user selection control, and displaying the user identification list.
In the embodiment of the present application, steps S250 to S260 may refer to the contents of the foregoing embodiments, and are not described herein again.
Step S270: and responding to the selection operation aiming at a target user identifier which is different from the current user identifier in the user identifier list, and switching the camera shooting parameters from the first shooting parameters corresponding to the current user identifier to the second shooting parameters corresponding to the target user identifier.
