Detailed ways

In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

At present, the penetration rate of mobile terminals in daily life is close to universal coverage. Among them, the camera module has become the main function point of the smart terminal. Users can take photos and videos through the camera function of the mobile terminal. Users can use the camera function of the mobile terminal to take photos and videos to record the moments of life, study and work.

At the same time, cameras are becoming more and more specialized based on the evolution of shooting functions, providing more hardware and software function setting items for users to use. For example, users can set high dynamic lighting rendering (HDR, High-Dynamic Range), Beauty, smart recognition and other setting items, after clicking to take a photo, the camera application will request the setting items to the camera service together, and finally complete the picture shooting.

When shooting with a mobile terminal, there may be cases where multiple users use the same terminal for shooting. For example, a family may use the same mobile terminal for shooting when traveling. However, usually different users may have different shooting habits. When shooting with a mobile terminal, different parameter values are also set for the setting items of many shooting parameters, and then shooting is performed. However, when changing users to shoot, due to the different shooting habits of users, it will involve the user to reset the parameter values of these setting items. In this case, the user's operation will be more cumbersome, and the user's ease of use and operability will be less. The shooting parameters are manually re-adjusted, which increases the difficulty of shooting and increases the cost of shooting time.

In view of the above problems, the inventor proposes a method, a device, a mobile terminal, and a storage medium for processing shooting parameters provided by the embodiments of the present application, which can efficiently switch shooting parameters corresponding to different users when different users use a mobile terminal to shoot, and Improve the convenience of user operation. The specific processing method of the shooting parameters will be described in detail in the following embodiments.

Please refer to FIG. 1. FIG. 1 shows a schematic flowchart of a method for processing shooting parameters provided by an embodiment of the present application. In a specific embodiment, the shooting parameter processing method is applied to the shooting parameter processing apparatus 400 shown in FIG. 9 and the mobile terminal 100 ( FIG. 10 ) configured with the shooting parameter processing apparatus 400 . The following will take a mobile terminal as an example to describe the specific process of this embodiment. Of course, it can be understood that the mobile terminal applied in this embodiment may be a smart phone, a tablet computer, a smart watch, etc., which is not limited here. The process shown in FIG. 1 will be described in detail below, and the processing method of the shooting parameters may specifically include the following steps:

Step S110: Display a shooting interface, where the shooting interface includes a user selection control, and the user selection control is used to trigger the selection of shooting parameters corresponding to different user identifiers.

In the embodiment of the present application, the shooting interface is an interface displayed in a shooting mode. When the mobile terminal enters the shooting mode, a shooting interface can be displayed. The shooting mode may be that when the mobile terminal detects that the system camera is turned on, the mobile terminal runs the system camera in the foreground to enter the shooting mode, and displays the shooting interface of the system camera.

The shooting mode can also be that when the mobile terminal detects that the third-party camera application is turned on, it runs the third-party camera application in the foreground to enter the shooting mode, and displays the shooting interface of the third-party system camera; the shooting mode can also be that the mobile terminal is in the shooting mode. When it is detected that the application is running, the camera is called to shoot, and the shooting mode is entered, and the shooting interface is displayed. The above-mentioned system camera, third-party camera application and other camera applications can be opened by detecting the touch operation on the control (icon) of the application. Of course, the opening of the camera application can also be triggered by voice control. Do limit.

In some embodiments, the shooting interface displayed by the mobile terminal may include a user selection control, and the user selection control may be used to trigger the selection of shooting parameters corresponding to different user identifiers. The user identifier is an identifier representing user identity information, and different user identifiers correspond to different users. For example, referring to FIG. 2, the shooting interface A1 includes a user selection control A2, and the user selection control can be used to trigger the selection of shooting parameters corresponding to different user IDs. When the user selects the control to operate, the selection of shooting parameters corresponding to different user identifiers can be triggered.

In some embodiments, please refer to FIG. 2 again, the shooting interface may further include a shooting button A3, which is used to trigger the shooting of an image, and may also refer to 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: preview area, shooting mode selection area, album button, camera switching button, etc. Of course, the specific content in the shooting interface can be limited. Among them, the preview area is used to display the shooting preview; the selection area of the shooting mode is used to select different shooting modes, such as night scene, video, portrait, photo and other shooting modes; the album button is used to trigger the start of the album; the camera switch button It can be used to switch the front camera and the rear camera, which is not limited here.

In some embodiments, shooting parameters corresponding to different user identities may be stored in the mobile terminal. It can be understood that different user identifiers correspond to different users, therefore, the shooting parameters corresponding to each user identifier correspond to one user. The shooting parameters corresponding to the user ID may be preset in the camera function of the mobile terminal for the user corresponding to the user ID; the shooting parameters corresponding to the user ID may also be shooting parameters automatically configured by the mobile terminal according to different user IDs, This is not limited. In addition, the shooting parameters corresponding to different user identifiers may be the same or different, which are not limited herein.

Step S120: Display a list of user IDs in response to a specified operation for the user-selected control.

In this embodiment of the present application, the mobile terminal may detect a touch operation in the shooting interface, and the touch operation may include a pressing operation, a click operation, a sliding operation, etc. acting on the shooting interface. When a designated operation on the user-selected control in the shooting interface is detected, it can be determined whether the touch operation is a preset designated operation. Wherein, a designated operation is pre-stored in the mobile terminal, and the designated operation can be used as a condition for whether to trigger the selection of shooting parameters corresponding to different user identifiers.

In some embodiments, when the mobile terminal detects a specified operation of a user-selected control, a list of user identifications may be displayed. The user ID list may include different user IDs, and these user IDs are associated with shooting parameters of different users. By displaying different user IDs, it is convenient for the user to select different user IDs, so that the corresponding user IDs can be selected. Select the shooting parameters.

In some embodiments, when the mobile terminal detects other operations on the user-selected controls, it can also respond. That is, when the mobile terminal responds to different touch operations on the user-selected controls, it can respond according to different touch operations. control operations and perform different responses. For example, the mobile terminal can also respond to other touch operations different from the specified operation, and display an editing page for editing the user ID list, so as to perform operations such as adding and deleting user IDs.

In some embodiments, the specified operation may be a click operation, that is, when the mobile terminal detects a click operation on a user-selected control, it will determine the click operation as a specified operation, and display the user ID in response to the specified operation. list. For example, please refer to FIG. 3 and FIG. 4 at the same time, by clicking on the user selection control A2, the interface shown in FIG. 4 can be triggered, and the interface shown in FIG. 4 includes the current user list A4 (equivalent to the above-mentioned user list A4) Identification list), the current user list A4 may include user identifications for the user to select different user identifications, thereby selecting shooting parameters corresponding to different user identifications.

Of course, the specified operation may also be other touch operations, for example, a pressing operation that satisfies a set pressing condition, and the like, which is not limited herein.

Step S130: In response to a selection operation for a target user ID different from the current user ID in the user ID list, switch the camera shooting parameters from the first shooting parameter corresponding to the current user ID to the second shooting parameter corresponding to the target user ID. shooting parameters.

In this embodiment of the present application, after displaying the user identification list, the mobile terminal may detect operations in the user identification list, for example, detect a touch operation of the user identification in the user identification list.

In some embodiments, the operation of the user identification in the user identification list may include a click operation, that is, the user can complete the selection of the user identification by clicking on the required user identification, and then the user identification The selection of the corresponding shooting parameters. Correspondingly, when the mobile terminal detects the click operation on the user identifier, it may determine that the selection operation on the user identifier is detected.

Further, when the mobile terminal determines that the selection operation on the user identification is detected, the user identification on which the selection operation is performed may be used as the target user identification, and whether the target user identification is the same as the current user identification. The current user identifier is the user identifier corresponding to the current shooting parameters of the mobile terminal. When the target user ID is the same as the current user ID, it means that the previous shooting parameters of the mobile terminal do not need to be adjusted; when the target user ID is different from the current user ID, it means that the user has selected other different user IDs, that is, the user needs to The shooting parameters corresponding to other user IDs are selected. Therefore, the mobile terminal can switch the camera shooting parameters from the first shooting parameters corresponding to the current user ID to the second shooting parameters corresponding to the target user ID.

In this embodiment of the present application, the shooting parameters corresponding to each user ID may include one or more types of shooting parameters, and the shooting parameters corresponding to different user IDs may include the same type of shooting parameters or different types of shooting parameters. For example, both the first shooting parameter and the second shooting parameter may include: HDR, intelligent recognition, face beauty (FB, Face Beauty), sensitivity (ISO), zoom ratio, focal length, exposure duration, exposure value, aperture size, and contrast For another example, the first shooting parameter may include HDR, smart recognition, and FB, and the second shooting parameter may include HDR, smart recognition, and zoom factor.

In some embodiments, the mobile terminal may read the second shooting parameter corresponding to the target user identifier, and then request the second shooting parameter to the camera service, thereby completing the switching of the camera shooting parameter. When the mobile terminal is changed from the current user to another user for shooting, the other user can adjust the camera shooting parameters to the shooting parameters corresponding to the user ID after selecting the corresponding user ID in the above manner, without the need for The manual setting simplifies the user's operation.

After the camera shooting parameters are switched, the second shooting parameter can be used to acquire the scene image according to the detected shooting control operation, so as to meet the shooting requirements of the user.

In addition, due to the native design of the current Android system, in order to meet the needs of users to quickly capture and shoot, the security camera (ie, the camera enabled when the screen is locked) can modify the parameters to shoot without unlocking. In a non-security shooting scene after unlocking, the camera settings can be modified globally in the security camera, which will affect normal shooting after a normal user unlocks it. With the method for processing the shooting parameters provided by the embodiments of the present application, since the shooting parameters are all corresponding to each user identifier when shooting with a camera, the problems caused by the security camera can be effectively avoided.

In the method for processing shooting parameters provided by the embodiments of the present application, the mobile terminal responds to a specified operation for the user selection control by displaying a shooting interface, and the shooting interface includes a user selection control for triggering the selection of shooting parameters corresponding to different user IDs , display the user ID list, and then in response to the selection operation for a target user ID different from the current user ID in the user ID list, switch the camera shooting parameters from the first shooting parameter corresponding to the current user ID to the second corresponding to the target user ID. shooting parameters, so that when different users use the mobile terminal to shoot, the shooting parameters corresponding to different users can be switched efficiently, which improves the convenience of user operations and avoids problems caused by security cameras.

Referring to FIG. 5 , FIG. 5 shows a schematic flowchart of a method for processing shooting parameters provided by another embodiment of the present application. The processing method of the shooting parameters is applied to the above-mentioned mobile terminal, and the flow shown in FIG. 5 will be described in detail below. The processing method of the shooting parameters may specifically include the following steps:

Step S210: Acquire characteristic information of the current user in response to the operation for triggering the startup of the camera.

In this embodiment of the present application, when the mobile terminal detects an operation for triggering the startup of the camera, it can respond to the operation, and when starting the camera, it can also determine the user ID corresponding to the current user, and set the camera shooting parameters as The shooting parameters corresponding to the current user identification, that is, the shooting parameters corresponding to the current user who is currently shooting.

In some embodiments, the mobile terminal may acquire feature information of the current user when responding to the operation for triggering the camera startup, that is, acquire feature information of the user who is currently using the mobile terminal and triggers the camera startup. The feature information may be the biometric feature information of the current user, such as fingerprint features, face features, iris features, and the like.

As an implementation manner, the feature information may include facial features. When acquiring the feature information of the current user, the mobile terminal may control the front camera to collect the current user's face image, and after extracting the facial features from the face image, Obtain the facial features of the current user.

As another embodiment, the feature information may include iris information, and the mobile terminal may control the front camera to collect the face image of the current user, and extract the iris feature according to the face image, thereby obtaining the iris feature of the current user.

As another embodiment, the feature information may include fingerprint features, and the mobile terminal may control the fingerprint collection module to collect the current user's fingerprint information by detecting the user's touch operation, so that according to the acquired fingerprint information, the The fingerprint characteristics of the current user.

Of course, the specific manner in which the mobile terminal obtains the feature information of the current user may not be limited.

Step S220: Match the feature information with the feature information corresponding to each user identifier.

In this embodiment of the present application, after acquiring the feature information of the current user, the mobile terminal may match the acquired feature information with the feature information corresponding to each user identifier to determine the user identifier corresponding to the current user. The mobile terminal may be preset with feature information corresponding to different user identities. Specifically, the mobile terminal may input the feature information corresponding to the user ID of the user according to the input operation of the feature information of different users, and store the feature information. . When the mobile terminal needs to determine the user ID corresponding to the current user, that is, the user's identity, the acquired feature information can be matched with the feature information corresponding to each user ID to determine the ID corresponding to the current user.

Step S230: when the feature information of the current user matches the feature information corresponding to the specified user ID, the specified user ID is used as the current user ID, and the camera shooting parameters are set as the shooting parameters corresponding to the specified user ID. parameter.

In this embodiment of the present application, after matching 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, according to the matching result, that the feature information of the current user matches the feature information corresponding to the specified user ID, the specified user ID can be used as the current user ID, that is, the specified user ID can be regarded as the user corresponding to the current user. logo. Then the mobile terminal may set the camera shooting parameters to the shooting parameters corresponding to the specified user identification when starting the camera.

In the above manner, when the camera is started, the camera shooting parameters can be automatically set according to the current user ID of the current user, which further simplifies the user's operation and improves the user experience.

In addition, in some other implementations, when it is determined that the identity information of the current user does not match the identity information corresponding to any user identification, the mobile terminal may also output first prompt information, where the first prompt information is used to prompt the user whether Shooting with default shooting parameters; or outputting second prompt information, where the second prompt information is used to prompt the user to add a user ID, and shoot parameters corresponding to the user ID.

In some embodiments, the shooting parameters corresponding to each user identification may include one setting scheme of the shooting parameters, or may include multiple setting schemes of the shooting parameters. That is to say, for a user, it may require a variety of setting solutions for shooting parameters. For example, different scenarios require different shooting parameters, so different solutions for shooting parameters can be set for different scenarios. When the mobile terminal sets the camera shooting parameters to the shooting parameters corresponding to the designated user identification, the mobile terminal can determine the number of shooting parameter sets corresponding to the designated identification. When the corresponding shooting parameter set is multiple, the shooting parameter set is further selected.

As an embodiment, when the shooting parameters corresponding to the specified user ID include multiple shooting parameter sets, the mobile terminal may obtain images of the current scene according to each shooting parameter set, and obtain multiple evaluation images, wherein each evaluation image Corresponding to a shooting parameter set; scoring the image quality of each evaluation image based on a pre-trained image quality assessment model to obtain multiple scores; setting the camera shooting parameters as shooting parameters in the target shooting parameter set, wherein the The target shooting parameter set is the shooting parameter set corresponding to the evaluation images whose scores satisfy the set scoring conditions.

The image quality assessment model may be pre-trained, and the training of the image quality assessment model may include: obtaining sample images and the marked scores of the sample images, and then using the sample images and their marked scores to train the initial model, and also That is, the initial model is trained with the sample image as input and the score as output, resulting in an image quality scoring 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 manners, the marked scores of the sample images may be derived from the scores of different users. Specifically, the mobile terminal may obtain the scores of the sample images from multiple users, obtain the scores of the multiple users, and then calculate the average of the scores of the multiple users. and variance, and then calculate the difference between the mean and variance; when the difference is greater than the preset difference, determine the highest and lowest scores of multiple user scores; The score is taken as the target user score; the average value of the scores of multiple target users is calculated; the average value of the scores of the multiple target users is determined as the score corresponding to the sample image; when the difference is not greater than the preset difference value, the average value of the scores of the multiple users is determined The score corresponding to the sample image. By determining the score of the sample image in the above manner, the evaluation information of different users can be referred to, thereby improving the accuracy of the label data of the sample image.

As another embodiment, when the shooting parameters corresponding to the specified user ID include multiple shooting parameter sets, the mobile terminal acquires a scene image, wherein each shooting parameter set corresponds to a shooting scene; recognizes the scene image, and obtains the current Shooting scene; based on the current shooting scene, setting the camera shooting parameters as shooting parameters in the shooting parameter set corresponding to the current shooting scene.

Understandably, when a user ID has multiple shooting parameter sets, the user corresponding to the user ID may set different shooting parameter setting schemes for different shooting scenarios, that is, set different shooting parameter sets. Therefore, the mobile terminal can use the scene recognition function provided by the camera service to identify the current shooting scene, and then determine the shooting parameter set corresponding to the current shooting scene from a variety of shooting parameter sets, and then use the camera shooting parameters Set to the shooting parameters in this shooting parameter set. Therefore, it is possible to automatically set shooting parameters corresponding to different shooting scenes, further simplifying user operations and improving user experience.

In this embodiment of the present application, when the camera is started, the mobile terminal may also determine whether the user-defined mode is enabled, and the user-defined mode is used to determine whether to perform the acquisition of the feature information of the current user in step S210 and subsequent steps. If the custom mode is turned on, you can set different camera shooting parameters according to different user IDs; if the user-defined mode is not turned on, when the camera starts up, the preview interface will be directly displayed, that is, normal shooting will be performed instead of Displays user selection controls in the capture interface.

Step S240: Acquire a user selection control corresponding to the specified user ID, wherein the styles of the user selection control corresponding to different user IDs are different.

In the embodiment of the present application, when displaying the photographing interface including the user selection control, the mobile terminal may also determine the user selection control corresponding to the specified user ID, wherein the user selection control corresponding to different user IDs has different styles. Understandably, the style of the user-selected control is associated with the user ID, so that the user can determine the user ID corresponding to the current camera shooting parameters through the displayed user-selected control, which is convenient for the user to determine whether the current camera shooting parameters Whether it is the corresponding shooting parameters for yourself. For example, the user selection control may include different avatar logos, and each different avatar logo corresponds to a user logo.

Step S250: Display a photographing interface, where the photographing interface includes a user selection control corresponding to the designated user identifier.

Step S260: In response to the specified operation for the user selection control, display a list of user IDs.

In this embodiment of the present application, for steps S250 to S260, reference may be made to the content of the foregoing embodiments, and details are not described herein again.

Step S270: In response to the selection operation for a target user ID different from the current user ID in the user ID list, switch the camera shooting parameters from the first shooting parameter corresponding to the current user ID to the second shooting parameter corresponding to the target user ID. shooting parameters.

In some embodiments, when responding to the selection operation for the target user identifier, the mobile terminal may also acquire the feature information of the current user, and match the feature information of the current user with the feature information corresponding to each user identifier; if the acquired feature information The information matches the feature information corresponding to the target user ID, indicating that the current user is the user corresponding to the target user ID, that is to say, the person using the mobile terminal has changed, so the camera shooting parameters can be set to the first shot corresponding to the current user ID. parameter, switch to the second shooting parameter corresponding to the target user ID; if the acquired feature information matches the feature information corresponding to the target user ID, the switching of the camera shooting parameters may not be performed, or a prompt message may be output to prompt the user whether to take the camera The shooting parameter is switched from the first shooting parameter corresponding to the current user ID to the second shooting parameter corresponding to the target user ID. By determining the identity of the current user before switching the camera shooting parameters, the camera shooting parameters are switched to the shooting parameters corresponding to other users in the event that the user mistakenly triggers the selection of the user ID.

In the method for processing shooting parameters provided by the embodiments of the present application, before triggering the camera to start and displaying the shooting interface, the shooting parameters are determined according to the feature information of the current user, so that the shooting parameters corresponding to the current user can be automatically set, which simplifies the user experience. operation. In addition, when it is necessary to switch the shooting parameters corresponding to other users, it is only necessary to perform a designated operation on the user selection control, and then select the user ID, and then the switching of the camera shooting parameters of other users can be realized, which simplifies the user operation. Improved user experience.

Referring to FIG. 6 , FIG. 6 shows a schematic flowchart of a method for processing shooting parameters provided by another embodiment of the present application. The processing method of the shooting parameters is applied to the above-mentioned mobile terminal, and the flow shown in FIG. 6 will be described in detail below. The processing method of the shooting parameters may specifically include the following steps:

Step S310: Based on different user identifiers, acquire at least one historical photographed image corresponding to each user identifier.

In the embodiment of the present application, a solution for automatically generating shooting parameters corresponding to each user identifier in advance is also provided. Specifically, at least one historical photographed image corresponding to each user identification may be acquired based on different user identifications. It is understandable that the historically photographed images of the user can reflect the scene taken by the user, the composition method of the photographing, etc., that is to say, can reflect the user's preferences. Therefore, the historically photographed images of the user can be used to determine the corresponding user ID. shooting parameters. The composition method may be, for example, the upper thirds composition, the lower thirds composition, the left thirds composition, the right thirds composition, the diagonal composition, the leading line composition, etc. The composition method may reflect the user's shooting habits.

Step S320: Determine the shooting scene and composition mode corresponding to each user identification according to the historical shooting images corresponding to each user identification.

In this embodiment of the present application, after acquiring the historically captured images corresponding to each user ID, the shooting scene and composition method corresponding to each user ID can be determined according to the historical captured images corresponding to each user ID.

In some embodiments, the scene recognition module in the camera service can be used to identify historically captured images to identify the shooting scene of each image; in addition, the composition of historically captured images can be obtained through a pre-trained convolutional neural network method, wherein the pre-trained convolutional neural network can be obtained by training the convolutional neural network from a large number of sample images marked with different composition methods. As a way, for each user ID, if there are multiple shooting scenes and multiple composition modes based on the shooting scenes and composition modes identified by its historical shooting images, it is possible to determine the shooting scene and composition mode with the highest number of occurrences. The composition mode is used as the shooting scene and composition mode corresponding to the user ID; as another mode, for each user ID, the shooting scene and composition mode identified according to its historical shooting images, if there are multiple shooting scenes and When there are multiple composition methods, various combinations can also be obtained according to the combination of different shooting scenes and composition methods in the historical shooting images. When generating shooting parameters later, shooting parameters can be generated according to each combination and used as a user ID. corresponding shooting parameters.

Step S330: Determine the shooting parameters corresponding to each user ID based on the shooting scene and composition mode corresponding to each user ID, and store the shooting parameters corresponding to each user ID.

In the embodiment of the present application, after acquiring the shooting scene and the composition method corresponding to each user identification, the shooting parameters corresponding to each user identification can be determined according to the shooting scene and the composition mode, and the corresponding shooting parameters of each user identification can be determined. Shooting parameters are stored. As a method, the corresponding relationship between different shooting scenes and composition methods and shooting parameters can be obtained in advance according to experiments. That is, the shooting parameters corresponding to each user ID are obtained. Understandably, the shooting parameters are usually related to the shooting scene, and the composition method is related to the user's shooting habits, and the shooting habits also determine the user's settings for shooting parameters. Therefore, by determining the shooting scene and composition mode corresponding to each user ID, Then, the shooting parameters are determined, and the shooting parameters corresponding to each user identification are saved, so that the process of setting the corresponding shooting parameters by the user can be omitted, and the operation of the user is further simplified.

Step S340: Display a shooting interface, where the shooting interface includes a user selection control, and the user selection control is used to trigger selection of shooting parameters corresponding to different user identifiers.

Step S350: Display a list of user IDs in response to a specified operation for the user-selected control.

Step S360: In response to the selection operation for a target user ID different from the current user ID in the user ID list, switch the camera shooting parameters from the first shooting parameter corresponding to the current user ID to the second shooting parameter corresponding to the target user ID. shooting parameters.
