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, and more setting items of shooting parameters are provided for users to set and use, for example, the users can set setting items such as focal length, zoom multiple and exposure duration, after clicking to shoot, camera applications can request the setting items to the camera service together, and finally picture shooting is completed.

When shooting with a mobile terminal, there may be situations where a user shoots in different shooting scenes, for example, shooting in a scenic spot a in the daytime, or shooting in the scenic spot a at night, and in different shooting scenes, the shooting effect required by the user is also different. Therefore, the user can adjust and set the shooting parameters according to the shooting scene of the user to shoot favorite images, but the user needs to manually adjust numerous shooting parameters, so that the shooting process is complicated.

In view of the above problems, the inventor provides an image capturing method, an image capturing apparatus, an electronic device, a server, and a storage medium, which are provided in an embodiment of the present application, and can capture a current captured scene according to a capturing parameter of a target image matched with a preview image when capturing is performed, without manually setting the capturing parameter by a user, so that convenience in user operation is improved, and a captured image with higher quality can be obtained. The specific image capturing method is described in detail in the following embodiments.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating an image capturing method according to an embodiment of the present disclosure. In a specific embodiment, the image capturing method is applied to the image capturing apparatus 400 shown in fig. 14 and the electronic device 100 (fig. 16) equipped with the image capturing apparatus 400. The following will describe a specific process of this embodiment by taking an electronic device as an example, and it is understood that the electronic device applied in this embodiment may be a smart phone, a tablet computer, a smart watch, smart glasses, and the like, which is not limited herein. As will be explained in detail with respect to the flow shown in fig. 1, the image capturing method may specifically include the following steps:

step S110: and acquiring a preview image corresponding to the current shooting scene.

In the embodiment of the application, the electronic device may acquire the preview image corresponding to the current shooting scene when the electronic device is in the shooting mode. The current shooting scene is a real scene which needs to be shot at present, for example, seaside at night.

In some embodiments, the electronic device may display a shooting interface, which is an interface displayed in a shooting mode. The electronic device may display a shooting interface when entering a shooting mode. The shooting mode may be that the electronic device 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. After the shooting interface is displayed, the electronic equipment can acquire a preview image of the current shooting scene through the camera and display the preview image in a preview area in the shooting interface. The shooting interface may include a selection area of a shooting mode, an album button, a camera switching button, a setting button of shooting parameters, and the like, in addition to the preview area.

The shooting mode can also be that when the electronic equipment 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 electronic equipment 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.

Step S120: and acquiring shooting parameters corresponding to a target image matched with the preview image, wherein the similarity between the target image and the preview image is greater than a preset threshold value.

In the embodiment of the application, after the electronic device acquires the preview image, in order to bring convenience to a user to shoot the current shooting scene, the electronic device may acquire shooting parameters corresponding to a target image matched with the preview image, so as to directly shoot the current shooting scene according to the shooting parameters. The target image is an image in which the similarity between the photographed image and the preview image is greater than a preset threshold, and a specific numerical value of the preset threshold may not be limited, for example, the preset threshold may be set to 50% to 70%, so that the target image similar to the preview image can be easily acquired, and for example, the preset threshold may be set to 70% to 90%, so that the target image similar to the preview image can be acquired more accurately.

As can be understood, the similarity between the target image and the preview image is greater than the preset threshold, which indicates that the image content in the preview image is similar to the image content in the target image, and therefore, the shooting parameters of the target image can be obtained for shooting the current shooting scene. For example, the target image is a self-portrait image when the sight a is self-portrait, the preview image is an image of the currently acquired sight a, and the target image is similar to the image content in the preview image at this time, and for example, the target image is an image of a hardy dog in a house, and the preview image is an image of another hardy dog in the house, and the target image is also similar to the image content in the preview image at this time.

As an embodiment, the above preset threshold may be a preset value, for example, when a camera application is installed, or when an operating system is installed (the operating system is taken by a system camera application), the camera applications are taken with the preset threshold; as another embodiment, the preset threshold may also be set by a user, and the user may set the preset threshold to be lower or higher according to the needs and preferences of the user, so as to meet the shooting needs of the user.

In some embodiments, the electronic device may store an image library, the image library includes a plurality of images, the images may be images captured in different shooting scenes, and the electronic device further stores shooting parameters of the images. The images stored by the electronic device may be images taken by the electronic device in history, images obtained from a server, and the like, and the specific way in which the electronic device obtains the images may not be limited. After the electronic equipment acquires the preview image, the image characteristics of the preview image and each image in the image library can be extracted through a model such as a deep neural network, and then the similarity between the preview image and each image is determined according to the similarity between the image characteristics.

In addition, the scores of the image quality of the images may be higher than the preset score, so that the matched shooting parameters of the target image can obtain an image with higher image quality when being used for shooting the image of the current shooting scene. The image quality score can be measured through image parameters such as definition, resolution, sharpness and the like, a corresponding standard value can be set for each type of image parameter, and the image quality score is determined through the difference between the image parameters of the image and the corresponding standard values; the image quality score can also be obtained through a pre-trained image quality evaluation model; the score for image quality may also be a user's score for image quality.

In other embodiments, the electronic device may also query the target image matching the preview image and the shooting parameters of the target image from the corresponding service platform through the network.

In some embodiments, the above shooting parameters may include, but are not limited to: zoom factor, focal length, sensitivity, exposure duration, exposure value, aperture size, or contrast. Of course, the specific shooting parameters may not be limited.

Step S130: and shooting the current shooting scene according to the shooting parameters to obtain a shot image.

In the embodiment of the application, after the shooting parameters corresponding to the target image matched with the preview image are acquired, the current shooting scene can be shot according to the acquired shooting parameters, so that the shooting image required by a user is acquired, the whole process does not need the user to manually set the shooting parameters, the operation of the user in the shooting process is reduced, and the user experience is improved. In addition, for a non-professional user, an image with better image quality can be shot according to different shooting scenes.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an image capturing method according to another embodiment of the present application. The image capturing method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 2, and the image capturing method may specifically include the following steps:

step S210: and acquiring a preview image corresponding to the current shooting scene.

In the embodiment of the present application, step S210 may refer to the contents of the foregoing embodiments, which are not described herein again.

Step S220: and acquiring a target image matched with the preview image.

In the embodiment of the application, before shooting the current shooting scene according to the shooting parameters, the electronic device can also acquire the target image to display the target image, so that a user can check the target image, judge whether the effect and the quality of the target image are satisfied, and then determine whether to shoot by using the acquired shooting parameters.

Step S230: and displaying the target image in a preset area in a shooting interface.

In the embodiment of the application, after the target image matched with the preview image is acquired, the electronic device can display the target image in a preset area in a shooting interface.

In one embodiment, the preset area may be a preview area of the shooting interface, and of course, the preset area may also be another area in the shooting interface, which is not limited herein. For example, the target image may be displayed in a partial area (e.g., a middle area) in the preview area, facilitating the user to view the target image; for another example, in the preview area, the preview area may be divided into two areas, wherein one area is used for displaying the preview image and the other area is used for displaying the target image, so that the user can conveniently view the target image, and simultaneously the preview image and the target image can be compared, so as to better confirm whether to shoot by adopting the shooting parameters.

In some embodiments, there may be a plurality of target images matching the preview image, at this time, the electronic device may acquire the plurality of target images matching the preview image, and when there are a plurality of target images, the electronic device may display the target images in the form of thumbnails when displaying the target images, so as to display the plurality of target images in the interface. When a user needs to magnify and view a certain target image, the user can select the target image to be viewed, and at the moment, the electronic equipment responds to the viewing operation and magnifies and displays the target image selected to be viewed.

Optionally, the electronic device may also rank the plurality of target images such that target images that some users are more likely to select are in a top position.

As an embodiment, the displaying, by the electronic device, a plurality of target images in a preset area may include: when a plurality of target images exist, acquiring the selection times of each target image; based on the selected times of each target image, sequencing the target images according to the sequence of the selected times from high to low; and displaying the target images in the preset area in the form of thumbnails based on the sorting result.

The number of times that the target image is selected may be the number of times that the shooting parameters of the target image are selected in the history shooting. When the image library corresponding to the target image is stored in the local electronic equipment, the selection times can be recorded in the local electronic equipment; when the electronic device queries the target image matching the preview image from the service platform, the electronic device may obtain the selection times from the service platform. In the embodiment, the target images are sorted according to the selection times and then displayed in the preset area as the thumbnails based on the sorting result, so that the user can more easily see the target images with the selection times, and the images are also images possibly selected by the user, thereby meeting the requirements of the user.

Optionally, when there are multiple target images, the electronic device may also screen out a target image with a selection number greater than a preset number according to the selection number of the target image, and display the target image in a preset area.

In some embodiments, when the target image is displayed in the preview area, the target image may be at a different level in the interface than the preview area, facilitating the user to view the target image. Optionally, the level of the target image in the interface may be higher than the level of the preview image in the interface.

Step S240: and acquiring shooting parameters corresponding to a target image matched with the preview image, wherein the similarity between the target image and the preview image is greater than a preset threshold value.

Step S250: and when a selection instruction of the target image is received, adjusting the camera shooting parameters to the shooting parameters corresponding to the target image.

In the embodiment of the application, after the electronic device displays the target image and acquires the shooting parameters, before shooting the current shooting scene according to the shooting parameters, the electronic device may determine whether the user selects the target image, so as to determine whether the user wants to shoot the image with the shooting parameters of the target image. When the electronic equipment detects a selection instruction of the target image, the camera shooting parameters are adjusted to the shooting parameters corresponding to the target image, so that the electronic equipment can shoot the current shooting scene according to the shooting parameters. For example, referring to fig. 3, the user may select the displayed target image by clicking.

In some embodiments, after receiving the selection instruction of the target image, the electronic device may further output a prompt message to prompt the user whether to shoot with the shooting parameter. The prompt information may be a pop-up window prompt, a voice prompt, etc., and the specific form of the prompt information may not be limited. For example, referring to fig. 4, the prompt content may be displayed in a pop-up window: and whether the shooting parameters of the image are to be shot or not is judged, a control selected by the user is displayed, and the shooting parameters are adjusted to the shooting parameters corresponding to the target image only when the user selects the control 'yes'.

In some embodiments, when there are a plurality of target images, the user may select the shooting parameters corresponding to at least two target images. When the electronic device detects the selection operation of the shooting parameters of the at least two target images, the electronic device can set the shooting parameters according to the shooting parameters of the at least two selected target images. As one mode, when the selection operation of the shooting parameters of at least two target images is detected, the number of times of selecting the selected target images may be obtained, then the weight of each target image is generated according to the number of times of selecting, and then a new shooting parameter is generated based on the shooting parameters and the weight of each target image. The sum of the number of selections of the selected target images can be obtained, that is, the number of selections of each target image is added, and then the weight of each target image is obtained based on the ratio of the number of selections of each target image to the sum. When the shooting parameters are generated, the shooting parameters can be weighted and summed according to each shooting parameter in the shooting parameters and then the new shooting parameters are obtained. For example, the selected target image includes an image a and an image B, and for the focal distance in the shooting parameters, the focal distance in the shooting parameters corresponding to the image a is 10 millimeters (mm), the focal distance in the shooting parameters corresponding to the target image B is 20mm, the weight corresponding to the image a is 0.6, and the weight corresponding to the shooting parameters corresponding to the image B is 0.4, then a new focal distance may be generated as follows: 10 × 0.6+20 × 0.4 ═ 14 mm. Of course, the above is merely an example, and does not constitute a limitation on the manner in which the imaging parameters are actually generated.

When a plurality of pictures are selected, generating weights according to the selection times, and setting photographing parameters according to the weights

Step S260: and shooting the current shooting scene according to the shooting parameters to obtain a shot image.

According to the image shooting method provided by the embodiment of the application, the target image is obtained and displayed while the shooting parameters corresponding to the target image matched with the preview image are obtained, the shooting parameters are adjusted to the shooting parameters of the target image under the condition that the user selects the target image, then the current shooting scene is shot according to the shooting parameters, and the shot image is obtained, so that the current shooting scene can be shot according to the shooting parameters of the target image matched with the preview image when shooting is performed, the user does not need to manually set the shooting parameters, the convenience of user operation is improved, and in addition, the shot image with higher quality can also be obtained. Moreover, the user can determine whether to select the corresponding shooting parameters according to the displayed target image, so that the requirements of the user can be met, and the user experience is improved.

Referring to fig. 5, fig. 5 is a schematic flowchart illustrating an image capturing method according to another embodiment of the present application. The image shooting method is applied to the electronic equipment.

An application environment of the video processing method provided by the embodiment of the present application is described below.

Referring to fig. 6, fig. 6 is a network structure diagram of an application scenario of the embodiment of the present application, where the electronic device 100 is in communication connection with the server 200, and the electronic device 100 may send image information of a preview image to the server 200 to obtain, from the server 200, shooting parameters corresponding to a target image matched with the preview image. The electronic device 100 may be a mobile phone, a tablet computer, or the like; the server 200 may be a conventional server, a cloud server, or the like. In the embodiment of the present application, the device types of the electronic device 100 and the server 200, and the type and the protocol of the communication network between the electronic device 100 and the server 200 are not limited.

As will be explained in detail with respect to the flow shown in fig. 5, the image capturing method may specifically include the following steps:

step S310: and acquiring a preview image corresponding to the current shooting scene.

Step S320: and sending the image information of the preview image to a server.

In the embodiment of the application, after acquiring the preview image, the electronic device may send image information of the preview image to the server to acquire, from the server, the shooting parameter corresponding to the target image matched with the preview image.

In some implementations, the image information can include at least a preview image. It can be understood that after the electronic device acquires the preview image, the electronic device directly sends the preview image to the server, and the server may query the shooting parameters of the target image matched with the preview image according to the preview image. And the information of the image characteristics corresponding to the preview image does not need to be extracted at the electronic equipment side and then sent to the server for inquiry, so that the processing capacity of the electronic equipment is effectively reduced, and the running speed of the electronic equipment is increased.

Of course, the image information may also include other information, for example, the image information may also include environment information of the current shooting scene, and the environment information may include a geographic location, weather, illumination, time, and the like, so that the server acquires a more matching target image.

Step S330: and receiving shooting parameters corresponding to the target image returned by the server, wherein the similarity between the target image and the preview image is greater than a preset threshold value.

In the embodiment of the application, after the electronic device sends the image information of the shot image to the server, the server determines the target image matched with the preview image through similarity matching between the images, and then the shooting parameters corresponding to the target image can be returned to the electronic device. Correspondingly, the electronic equipment can receive shooting parameters corresponding to the target image returned by the server.

In some embodiments, the server may also return the target image to the electronic device, and the electronic device may display the target image by referring to a manner of displaying the target image in the previous embodiment, so that the user may view an effect and image quality of the target image, and then determine whether to select a shooting parameter of the target image to shoot the current shooting scene.

In some implementations, the above servers can include servers corresponding to application stores and/or theme stores. Referring to fig. 7, the electronic device may acquire a similarity map (target image) and photographing parameters matching the preview image from the app store and the subject store according to the preview image. It is understood that a large number of interface themes may be stored in the application store and the server corresponding to the theme store, and the shooting parameters of the image corresponding to the interface themes may be stored. When the user likes the target image, the server can download the interface theme of the target image through corresponding operation. Therefore, the image capturing method may further include: sending a downloading request to the server, wherein the downloading request is used for downloading the interface theme corresponding to the target image; and receiving an interface theme returned by the server according to the downloading request, and storing the interface theme. Therefore, a new diversion mode is provided for the application store and the theme store, the user is guided to the store in the image shooting stage, and the wallpaper and the theme are recommended and purchased.

Step S340: and shooting the current shooting scene according to the shooting parameters to obtain a shot image.

According to the image shooting method provided by the embodiment of the application, after the electronic equipment acquires the preview image of the current shooting scene, the preview image is sent to the server, so that the shooting parameters of the target image matched with the preview image are acquired from the server, and the server generally has higher processing performance, so that the shooting parameters can be acquired more quickly, and the shooting experience is improved. In addition, the electronic equipment does not need to store a large number of images and match the similarity between the images, so that the storage space and the processing capacity of the electronic equipment are effectively saved, and the running speed of the electronic equipment is increased.

Referring to fig. 8, fig. 8 is a schematic flowchart illustrating an image capturing method according to still another embodiment of the present application. The image capturing method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 8, and the image capturing method may specifically include the following steps:

step S410: and acquiring a preview image corresponding to the current shooting scene.

Step S420: and sending the image information of the preview image to a server.

Step S430: and receiving shooting parameters corresponding to the target image returned by the server, wherein the similarity between the target image and the preview image is greater than a preset threshold value.

Step S440: and shooting the current shooting scene according to the shooting parameters to obtain a shot image.

In the embodiment of the present application, steps S410 to S440 may refer to the contents of the foregoing embodiments, and are not described herein again.

Step S450: and if an adjusting instruction of the shooting parameters is received within a preset time, adjusting the shooting parameters based on the adjusting instruction.

In the embodiment of the application, after the electronic device captures the current captured scene by using the acquired capturing parameters to obtain the captured image, when the user is not satisfied with the capturing effect of the captured image, the electronic device may manually adjust the capturing parameters to capture the image again.

In some embodiments, the electronic device may display an adjustment interface of the shooting parameters in response to the operation of the user, for example, please refer to fig. 9, which shows a shooting interface a1, so as to adjust the shooting parameters based on the shooting parameters corresponding to the target image, so that a satisfactory image can be obtained by shooting subsequently. Moreover, on the basis of the shooting parameters corresponding to the target image, the shooting parameters are adjusted, the situation that the user sets the shooting parameters without a direction is avoided, and the user can conveniently adjust the shooting parameters.

Step S460: and shooting the current shooting scene again based on the adjusted shooting parameters to obtain a latest shot image as the current shot image.

In the embodiment of the application, after the electronic device adjusts the shooting parameters according to the adjustment instruction of the user, the electronic device may re-shoot the current shooting scene based on the adjusted shooting parameters, and obtain the latest shot image as the current shooting image. After acquiring the current shot image, the electronic device may store the current shot image.

In some embodiments, the electronic device may store the currently captured image upon receiving a storage instruction to store the currently captured image. In addition, since the user usually inputs the storage instruction only when the user is satisfied with the current captured image, the electronic device may delete the previous captured image, that is, delete the captured image captured with the capturing parameters corresponding to the target image.

Step S470: and acquiring an image quality score corresponding to the current shot image as a first score, and acquiring an image quality score corresponding to the target image as a second score.

In the embodiment of the application, the shooting parameters are adjusted on the basis of the shooting parameters of the target image, and then the current shooting image is obtained by shooting again. Therefore, the shooting parameters corresponding to the current shot image are different from the shooting parameters corresponding to the target image, and the shooting effects and the quality of the two images are also different. The electronic device may further acquire an image quality score corresponding to the currently photographed image as a first score and an image quality score corresponding to the target image as a second score to compare the first score with the second score, thereby determining whether the image quality of the currently photographed image is better than the photographing quality of the target image. It is understood that, when the first score is greater than the second score, it indicates that the image quality of the current captured image is better than the capture quality of the target image; when the first score is less than or equal to the second score, the image quality of the currently photographed image is not superior to the photographing quality of the target image.

In some embodiments, the image quality score may be determined by image parameters such as sharpness, resolution, sharpness, etc., for example, a respective standard value may be set for each type of image parameter, and the image quality score is determined by the difference between these image parameters of the image and the corresponding standard values; the image quality score can also be obtained through a pre-trained image quality evaluation model; the image quality score may also be a user's score for image quality.
