Detailed Description

For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given in the present application without inventive step, shall fall within the scope of protection of the present application.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Referring to fig. 1, a schematic view of an electronic device provided in an embodiment of the present application is shown. In fig. 1, an electronic device is exemplified by a mobile phone 100, and fig. 1 shows a front view and a rear view of the mobile phone 100, two

front cameras

111 and 112 are arranged on the front side of the mobile phone 100, and four

rear cameras

121, 122, 123 and 124 are arranged on the rear side of the mobile phone 100. By configuring a plurality of cameras, a plurality of shooting modes, such as a forward shooting mode, a backward shooting mode, a forward and backward double shooting mode and the like, can be provided for a user. The user can select a corresponding shooting mode to shoot according to the shooting scene so as to improve the user experience.

It is to be understood that the illustration of fig. 1 is merely an exemplary illustration and should not be taken as a limitation on the scope of the present application. For example, the number and positions of cameras may be different for different mobile phones. In addition, the electronic device according to the embodiment of the present application may be a tablet PC, a Personal Computer (PC), a Personal Digital Assistant (PDA), a smart watch, a netbook, a wearable electronic device, an Augmented Reality (AR) device, a Virtual Reality (VR) device, an in-vehicle device, a smart car, a smart audio, a robot, smart glasses, a smart television, or the like, in addition to a mobile phone.

It should be noted that, in some possible implementations, the electronic device may also be referred to as a terminal device, a User Equipment (UE), and the like, which is not limited in this embodiment of the present application.

In an actual application scene, a user performs video shooting through the electronic device, and in the video shooting process, in order to perform personalized shooting, the user may change some shooting parameters, such as a filter used in shooting, a shooting rate in shooting, a shooting frame in shooting, and the like. Illustratively, the user may employ the filter 1 in order to highlight the photographed scene during photographing, or may employ the filter 2 in order to highlight the photographed person. At present, in the shooting process, if shooting parameters are changed, the shooting parameters still keep the current values unchanged after shooting is completed. For example, to perform personalized photography, the filter used by the user is LUT2, and photography is performed using 2-fold zoom, as shown in (1) in fig. 2. After the shooting is completed, the shooting parameters will still keep the current values unchanged, as shown in (2) in fig. 2. In this way, when the next shooting is performed, the user needs to restore the shooting parameters changed in the previous shooting to the initial values before performing normal shooting. When the shooting parameters are changed, the shooting parameters need to be restored to the initial values by the user, so that the user operation is increased, and the user experience is poor.

The embodiment of the application provides a video shooting method, after video image shooting is finished, parameter recovery information can be determined according to the running state of a camera application, and the value of a first target shooting parameter in the camera application is recovered to a preset initial value according to the parameter recovery information. The method and the device can automatically restore the first target shooting parameter to the initial value after shooting is completed, do not need manual restoration of a user, can reduce user operation, improve the intelligence of the electronic equipment, and accordingly improve user experience.

Referring to fig. 3, a schematic flow chart of a video shooting method according to an embodiment of the present application is shown. The method can be applied to the electronic device shown in fig. 1, and mainly includes the following steps, as shown in fig. 3.

Step S301, in response to the shooting end operation, stops shooting the video image, and determines the running state of the camera application.

In the embodiment of the application, when a user uses the electronic device to shoot a video, the electronic device can acquire a video image through a camera therein, and when the user needs to end the video shooting, the user can send a shooting end operation to the electronic device. At this time, the electronic apparatus may receive the shooting end operation, and stop the shooting of the video image according to the shooting end operation.

Since the electronic apparatus can restore the values of some shooting parameters that the user changed at the time of shooting to their initial values. At this time, the electronic device needs to detect the running state of the current camera application when the video image stops being shot. That is, when the electronic device stops shooting the video image, it needs to detect whether the camera application is in a current running state, a background running state, or a running ending state.

The running state of the camera application refers to the current working state of the camera application. The operating states of the camera application include: a current running state, or a background running state, or an end running state. When the running state of the camera application is the current running state, the current camera application is in use and is visible to a user, and the display interface of the electronic device is a preview interface of the camera application in the current camera mode and can be operated by the user. The current running state of the camera application comprises a state of staying in a preview interface in a current camera mode, a state of switching modes, such as switching from a movie mode to a photo mode or a video mode or other modes, and the like. When the running state of the camera application is a background running state, it is indicated that the current camera application is still in the running state and the running is not finished, but the display interface of the electronic device is not a shooting preview interface of the camera application, and the camera application is not operated by the user and runs in a background which is not seen by the user. When the running state of the camera application is the state of ending running, the camera application is closed.

Step S302, determining parameter recovery information of the camera application according to the running state of the camera application.

The parameter recovery information is related to shooting parameters that need to be recovered to a preset initial value in the camera application.

In the embodiment of the present application, the parameter recovery information is preset. The parameter recovery information corresponding to the operating state of different camera applications may be different. And when the electronic equipment determines to stop shooting the video image, determining parameter recovery information matched with the current running state according to the running state of the current camera application after the running state of the current camera application.

It should be noted that, for different operation states of the camera application, the corresponding shooting parameters that need to be restored to the preset initial values are different, so that different parameter restoration information can be set in advance according to the different operation states of the camera application.

Further, when the running state of the camera application is the current running state, the parameter recovery information includes at least one piece of relevant information of the shooting zoom parameter, the shooting rate parameter and the shooting frame parameter. When the running state of the camera application is a background running state or a running finishing state, the parameter recovery information comprises at least one piece of relevant information of filter parameters, shooting zoom parameters, shooting rate parameters and shooting picture parameters. That is, the three parameters, i.e., the shooting zoom parameter, the shooting rate parameter, and the shooting frame parameter, may be parameters that need to be restored to a preset initial value when the video image shooting is stopped and the camera application is in the current operating state, or when the video image shooting is stopped and the camera application is switched to background operation, or when the video image shooting is stopped and the camera application is stopped. And the filter parameters only switch the camera application to the background operation while stopping shooting the video image, or restore the camera application to the preset initial value while stopping shooting the video image. When the shooting of the video image is stopped and the camera application is in the current running state, it is described that the electronic device ends the shooting of the video image, but the electronic device is currently running the camera application, and the user can operate the camera application. At this time, the filter parameters are not restored to the preset initial values, but the values are kept unchanged until the filter conforming to the current shooting scene is automatically recommended according to the video image of the current shooting scene, or the user selects other filters for shooting.

Or when the running state of the camera application is the current running state or the background running state or the running ending state, the parameter recovery information comprises at least one piece of relevant information of filter parameters, shooting zoom parameters, shooting rate parameters and shooting picture parameters. That is, the four parameters, i.e., the filter parameter, the shooting zoom parameter, the shooting rate parameter, and the shooting frame parameter, may be parameters that need to be restored to a preset initial value when the video image shooting is stopped and the camera application is in the current operating state, or when the video image shooting is stopped and the camera application is switched to the background operation, or when the video image shooting is stopped and the camera application is stopped. Therefore, in the scene, as long as the video image shooting is completed, at least one of the four parameters, i.e., the filter parameter, the shooting zoom parameter, the shooting rate parameter and the shooting frame parameter, needs to be restored to the preset initial value.

Or when the running state of the camera application is the current running state, the parameter recovery information comprises the relevant information of the shooting rate parameter; when the running state of the camera application is a background running state or a running ending state, the parameter recovery information includes related information of at least one of a shooting rate parameter, a filter parameter and an IMAX (Image Maximum) parameter. That is, when the video image is stopped from being shot and the camera application is in the current running state, only the parameter value of the shooting rate parameter needs to be restored to the preset initial value. At least one of the filter parameter and the IMAX parameter remains unchanged at the current value. And when the video image shooting is stopped and the camera application is switched to the background operation, or when the video image shooting is stopped and the camera application is stopped, at least one of the shooting rate parameter, the filter parameter and the IMAX parameter can be restored to a preset initial value.

It should be noted that, the electronic device is preset with parameter recovery information corresponding to different operating states of the camera application. The shooting parameters included in the parameter restoration information that need to be restored to the preset initial values are preset according to actual needs, and may include other shooting parameters listed above, such as AI intelligent recommendation parameters, and the like, which is not limited in this application. When the AI intelligent recommendation is started, the electronic equipment can intelligently recommend proper filter parameters according to the current shooting scene.

And step S303, restoring the first target shooting parameter in the camera application to a preset initial value according to the parameter restoring information of the camera application.

Wherein the first target shooting parameter is at least one of the shooting parameters indicated in the parameter recovery information.

In this embodiment of the application, after determining the parameter recovery information according to the running state of the camera application, the electronic device may determine the first target shooting parameter in the parameter recovery information, and recover a parameter value of the first target shooting parameter to a preset initial value.

However, when the first target photographing parameter is determined based on the parameter restoration information, there are two ways. One way is to determine all the shooting parameters indicated in the parameter recovery information as the first target shooting parameters for convenient implementation, and at this time, all the shooting parameters recorded in the parameter recovery information need to be recovered to their initial preset values. Another way is that in order to reduce the resources used, a shooting parameter whose current value is not a preset initial value among shooting parameters recorded in the parameter recovery information may be determined as the first target shooting parameter. In this way, only the shooting parameters whose parameter values have been changed may be determined as the first target shooting parameters, and the shooting parameters whose parameter values have not been changed may not be subjected to the processing of restoring the preset initial values. The specific implementation mode is as follows:

further, according to the parameter recovery information of the camera application, recovering the first target shooting parameter in the camera application to the preset initial value includes: and according to the parameter recovery information applied by the camera, determining all the shooting parameters indicated by the parameter recovery information as first target shooting parameters, and recovering the first target shooting parameters to preset initial values.

In this way, the shooting parameters to be restored to the preset initial value recorded in the parameter restoration information can all be determined as the first target shooting parameters, and the parameter values of the first target shooting parameters can be restored to the preset initial value. In this manner, the parameter value of the first target shooting parameter may be restored to the preset initial value regardless of whether the current parameter value of the current first target shooting parameter is the preset initial value.

Or, according to the parameter recovery information of the camera application, recovering the first target shooting parameter in the camera application to a preset initial value includes: and determining the shooting parameters with parameter values different from the preset initial values in the shooting parameters indicated by the parameter recovery information as first target shooting parameters according to the parameter recovery information applied by the camera, and recovering the first target shooting parameters to the preset initial values.

Since all the shooting parameters recorded in the parameter recovery information need to be recovered to the preset initial value, and in the process of shooting the video image by the user, only the values of some of the shooting parameters may be changed, and the values of all the shooting parameters indicated in the parameter recovery information are not changed, in order to reduce the resources occupied by the processor and the memory, the shooting parameter whose parameter value is changed in all the shooting parameters indicated in the parameter recovery information may be determined as the first target shooting parameter, and at this time, the parameter value of the first target shooting parameter is recovered to the preset initial value.

It should be noted that the preset initial value of each shooting parameter is preset, and when the user enters the camera application and does not set the value of the shooting parameter, the parameter value of each shooting parameter is set as the corresponding preset initial value by default. The preset initial values corresponding to different shooting parameters are different, and in the actual application process, each preset initial value can be set according to the actual requirement of a user.

Further, according to the parameter recovery information of the camera application, recovering the first target shooting parameter in the camera application to the preset initial value includes: and when the parameter recovery information carries the recovery value of the first target shooting parameter, recovering the first target shooting parameter in the camera application to the recovery value of the first target shooting parameter carried in the parameter recovery information according to the parameter recovery information of the camera application.

Specifically, the shooting parameters that need to be restored to the preset initial values may be preset in the parameter restoration information, and for convenience of implementation, when the shooting parameters that need to be restored to the preset initial values are set in the parameter restoration information, the restored preset initial values may be set at the same time, that is, the preset initial values corresponding to the shooting parameters that need to be restored to the preset initial values are set. At this time, after the electronic device acquires the parameter recovery information, the electronic device may analyze the parameter recovery information to acquire the shooting parameters and the corresponding preset initial values that need to be recovered to the preset initial values when the camera is applied in different operation states. The electronic equipment can determine the first target shooting parameters according to the parameter recovery information, determine the recovery values of the first target shooting parameters in the parameter recovery information, and update the parameter values of the first target shooting parameters by taking the determined recovery values of the first target shooting parameters as preset initial values.

Further, the preset initial values of the filter parameters include: the initial LUT is used to tone the corresponding parameter values. That is, in the embodiment of the present application, a plurality of LUT tone filters are provided in the electronic device, one of the LUT tone filters is selected as an initial LUT tone, and a preset initial value of a filter parameter is set as a parameter value corresponding to the initial LUT tone. For example, filters for a plurality of LUT tones provided in the electronic device are nostalgic, morning light, cyan, blue tones, and the like. A filter of the nostalgic LUT tone may be used as the initial LUT tone and preset initial values of filter parameters may be set as parameter values corresponding to the nostalgic LUT tone. In this way, the preset initial value of the filter parameter applied by the camera is the parameter value corresponding to the initial LUT tone. Thus, when the electronic device is running a camera application, the captured video image is by default superimposed with the initial LUT tone.

Or, the preset initial values of the filter parameters include: and (4) parameter values corresponding to the original tones. That is, in the embodiment of the present application, the preset initial value of the filter parameter is set as the parameter value corresponding to the original tone. At this time, when the electronic device runs the camera application, the shot video image is the original image by default, that is, the video image without any filter effect superimposed thereon. That is to say, the initial default state of the filter applied by the camera is the closed state, and when the filter parameter is restored to the initial preset value, the filter applied by the camera is restored to the closed state.

Further, if the running states of the camera applications are different, the shooting parameters to be restored to the preset initial values included in the parameter restoration information are different. Therefore, the first target photographing parameters are different when the operation states of the camera applications are different. The method comprises the following specific steps:

when the running state of the camera application is a current running state, the first target shooting parameter comprises: at least one of a shooting zoom parameter, a shooting rate parameter and a shooting frame parameter; when the running state of the camera application is a background running state or an end running state, the first target shooting parameter includes: at least one of a filter parameter, a photographing zoom parameter, a photographing rate parameter, and a photographing frame parameter. That is, when the video image capturing is finished and the camera application state is in the current running state, at least one of the capturing zoom parameter, the capturing rate parameter, and the capturing frame parameter may be determined as the first target capturing parameter, so that at least one of the capturing zoom parameter, the capturing rate parameter, and the capturing frame parameter may be restored to the preset initial value. When the video image shooting is finished, the camera application is switched to the background operation, namely when the video image shooting is finished and the camera application state is the background operation state, or when the video image shooting is finished and the camera application is closed, namely when the video image shooting is finished and the camera application state is the end operation state, at least one of the filter parameter, the shooting zoom parameter, the shooting rate parameter and the shooting picture parameter can be determined as the first target shooting parameter, so that at least one of the filter parameter, the shooting zoom parameter, the shooting rate parameter and the shooting picture parameter can be restored to a preset initial value.

Or when the running state of the camera application is a current running state, a background running state or a running ending state, the first target shooting parameter includes: at least one of a filter parameter, a photographing zoom parameter, a photographing rate parameter, and a photographing frame parameter. That is, when the video image shooting is finished and the camera application state is in the current running state, or when the video image shooting is finished and the camera application is switched to the background running state, that is, when the video image shooting is finished and the camera application state is the background running state, or when the video image shooting is finished and the camera application is closed, that is, when the video image shooting is finished and the camera application state is the end running state, at least one of the filter parameter, the shooting zoom parameter, the shooting rate parameter and the shooting frame parameter can be determined as the first target shooting parameter, so that at least one of the filter parameter, the shooting zoom parameter, the shooting rate parameter and the shooting frame parameter can be restored to the preset initial value.

Or, when the running state of the camera application is the current running state, the first target shooting parameter includes: a shooting rate parameter; when the running state of the camera application is a background running state or a running ending state, the first target shooting parameter includes: at least one of a shooting rate parameter, a filter parameter, and an IMAX parameter. That is, when the video image photographing is ended and the camera application state is in a currently running state, the photographing rate parameter may be determined as the first target photographing parameter, so that the photographing rate parameter may be restored to a preset initial value. When the video image shooting is finished, the camera application is switched to the background operation, that is, when the video image shooting is finished, the camera application state is the background operation state, or when the video image shooting is finished, the camera application is closed, that is, when the video image shooting is finished, the camera application state is the end operation state, at least one of the filter parameter and the IMAX parameter can be determined as the first target shooting parameter, so that at least one of the filter parameter and the IMAX parameter can be recovered to the preset initial value.

In summary, after the video image shooting is finished, the parameter recovery information can be determined according to the running state of the camera application, and the value of the first target shooting parameter in the camera application is recovered to the preset initial value according to the parameter recovery information. The method and the device can automatically restore the first target shooting parameter to the initial value after shooting is completed, do not need manual restoration of a user, can reduce user operation, improve the intelligence of electronic equipment, and accordingly improve user experience.

Referring to fig. 4, a schematic flow chart of another video shooting method provided in the embodiment of the present application is shown. The method is different from the embodiment shown in fig. 3 described above in that a step of setting the shooting parameters by the user is added, and as shown in fig. 4, the method mainly includes the following steps.

Step S401, in response to the shooting parameter setting operation, sets a value of a second target shooting parameter of the camera application according to the shooting parameter setting operation.

The shooting parameter setting operation carries a setting value of a second target shooting parameter; the second target shooting parameter is a shooting parameter whose parameter value is set by the user.

In the embodiment of the application, before video shooting, a user can set shooting parameters, at this time, the user can send shooting parameter setting operation to the electronic device, and the shooting parameter setting operation carries values of the shooting parameters set by the user. Namely the setting value carrying the second target shooting parameter. After receiving the shooting parameter setting operation, the electronic device may respond to the shooting parameter setting operation, set a value of a second target shooting parameter in the camera application according to the shooting parameter setting operation, and update the value to a setting value of the second target shooting parameter carried in the shooting parameter setting operation.

Step S402, in response to the shooting end operation, stops shooting the video image, and determines the running state of the camera application.

Specifically, refer to step S301, which is not described herein again.

Step S403, determining parameter recovery information of the camera application according to the running state of the camera application.

Specifically, refer to step S302, which is not described herein again.

And S404, restoring the first target shooting parameter in the camera application to a preset initial value according to the parameter restoring information of the camera application.

Specifically, refer to step S303, which is not described herein again.

And S405, determining a third target shooting parameter according to the second target shooting parameter and the first target shooting parameter, and keeping the parameter value of the third target shooting parameter unchanged.

The third target shooting parameter is related information of the shooting parameters which do not need to be restored to the preset initial value in the second target shooting parameters.

In the embodiment of the application, when the user sets the shooting parameters of the camera application, after some shooting parameters are set, the camera application is kept unchanged when the operation of the camera application is finished until the parameter values are reset by the user next time. The values of some shooting parameters need to be restored to preset initial values. Based on this, in the present application, the shooting parameters that carry their setting values in the shooting parameter operation and do not need to be restored to the preset initial values after the video image shooting is finished are referred to as third target shooting parameters. Therefore, the second target shooting parameter may include a third target shooting parameter.

Further, the first target photographing parameter and the third target photographing parameter are different photographing parameters.

The third target photographing parameter includes: at least one of a parameter of the HDR10 switch state, a parameter of the AI intelligence recommendation switch state, and a parameter of the flash switch state.

It should be noted that the third target shooting parameter may also be other parameters, such as a shooting zoom parameter, a shooting frame parameter, and the like, which is not limited in this application.

In this embodiment of the application, after the video image capturing is finished, the parameter value of the third target capturing parameter does not need to be restored to the initial value, but remains unchanged, so that after the video image capturing is stopped, when the second target capturing parameter includes the third target capturing parameter, that is, before the video image is captured, the user sets the parameter value of the third target capturing parameter, at this time, after the video image capturing is finished, the electronic device keeps the parameter value of the current third target capturing parameter unchanged. That is, after the video image capturing is finished, the electronic device does not restore the parameter value of the third target capturing parameter to the preset initial value.

Illustratively, as shown in fig. 5 (1), in response to a user operating icon 501 of the "camera" application in the cell phone home screen interface, the cell phone displays interface 502 as shown in fig. 5 (2). The interface 502 is a preview interface for mobile phone photographing, and the interface 502 further includes a "portrait" mode, a "video" mode, a "movie" mode, and a "professional" mode. In response to the user's operation of selecting the "movie" mode 503, the cellular phone displays an interface 504 as shown in (1) in fig. 6. Interface 504 is a preview interface before the handset records. As shown in fig. 6 (1), the interface 504 includes an HDR10 control 505, an LUT control 506, and a zoom control 507. Wherein, the turning on of the HDR10 control 505 represents that the electronic device takes a 10bit video image. The user may select the desired LUT by clicking on the LUT control 506. The zoom control 507 is used to change the focal length of the shot. For example, as shown in (1) of fig. 6, in response to a user operation of the LUT control 506, the handset displays an interface as shown in (2) of fig. 6. The interface includes a plurality of LUT filters disposed within the electronic device, including LUT1, LUT2, LUT 3. Assuming that, in the movie mode, the user has turned on the HDR10 control and selected the LUT2, and photographs with 2 times zoom, the cell phone displays the interface 801 shown in fig. 7. In this interface 801, the HDR10 control is turned on, and the LUT2 and 2-fold zoom are used to display the preview image. In response to a user selecting a shooting operation, video shooting is performed.

At this time, the shooting parameters set by the user are to start the 4K HDR control, the filter parameters are LUT2, and the shooting zoom parameters are zoom by 2 times, that is, the second target shooting parameters are the 4K HDR control parameters, the filter parameters, and the shooting zoom parameters. In response to the user selecting a shooting end operation, the electronic device determines a state in which the camera application is currently located. If the camera application of the electronic equipment is in the current running state, the electronic equipment determines that the camera application is the parameter recovery information in the current running state. It is assumed that the parameter recovery information includes the shooting zoom parameter. That is, when the shooting is finished and the camera application is in the current running state, that is, the display interface of the electronic device is still the preview interface of the movie mode, the electronic device may determine the first target shooting parameter as the shooting zoom parameter. And determining the 4K HDR control parameter and the filter parameter as a third target shooting parameter. At this time, when the shooting is finished, the electronic device only restores the parameter value of the shooting zoom parameter to a preset initial value, that is, to 1 time zoom. The handset displays an interface 802 as shown in fig. 8 (1). While the 4K HDR control parameter and the filter parameter are still the values selected by the user and are not changed.

If the camera application of the electronic equipment is in the running ending state, the electronic equipment determines the parameter recovery information of the camera application in the running ending state. It is assumed that the parameter recovery information includes filter parameters and shooting zoom parameters. That is, when the shooting is ended and the camera application is in a state of ending the running, that is, the electronic apparatus turns off the camera application. The electronic device may determine the first target photographing parameter as a photographing zoom parameter polar filter parameter. The 4K HDR control parameter is determined as the third target photographing parameter. At this time, when the electronic device finishes shooting, the parameter value of the shooting zoom parameter is restored to the preset initial value, that is, to 1 time zoom, and the filter parameter is restored to the default filter LUT1, while the 4K HDR control parameter is still the value selected by the user and is not changed, refer to the interface 803 shown in fig. 8 (2).

Further, in step S302, if it is determined that the camera application is in the current running state when the shooting is finished, it indicates that the display interface of the electronic device is still the shooting preview interface in the camera application. Since there is a user closing the camera application or switching to background running. Therefore, the operation state of the camera application also changes. Due to the difference of the running state of the camera application, the corresponding parameter recovery information is different. That is, the camera applies different operation states, and the shooting parameters that need to be restored to the preset initial values are also different. When the running state of the camera application is switched from the current running state to the background running state, the parameter value of the shooting parameter corresponding to the background running state and needing to be restored to the preset initial value also needs to be restored. Similarly, when the running state of the camera application is switched from the current running state to the running ending state, the parameter value of the shooting parameter that needs to be restored to the preset initial value corresponding to the running ending state also needs to be restored.

Similarly, when the running state of the camera application is the background running state, the user may close the camera application, that is, kill the process of the camera application, and at this time, the state of the camera application may be switched from the background running state to the running ending state. Because the running states of the camera application are different, and the corresponding parameter recovery information is different, when the running state of the camera application is switched from the background running state to the running ending state, the parameter value of the shooting parameter which is required to be recovered to the preset initial value and corresponds to the running ending state also needs to be recovered.

In this case, if the operation state of the camera application is the operation state in which the camera application is ended when the video shooting is stopped in step S402, the following steps need not be executed. If the operation state of the camera application is the current operation state when the video capturing is stopped in step S402, the following steps S406 to S408 are performed. If the operation state of the camera application is the post-operation state, the following steps S409 to S411 are executed.

It should be noted that if the parameter restoration information corresponding to the state of ending the operation is the same as the parameter restoration information corresponding to the state of background operation, the following steps S406 to S4 and S08 need only be executed, and the steps S409 to S411 need not be executed.

Step S406, when the running state of the camera application is the current running state, determining whether the running state of the camera application is switched to the background running state or the running state is ended.

Specifically, if it is determined that the running state of the camera application is the current running state when the shooting is stopped in step S402, the electronic device needs to restore the shooting parameters corresponding to the current running state to the preset initial values, where the shooting parameters need to be restored to the preset initial values. The user can close or switch the camera application of the electronic equipment to the background operation at any time, and the operation state of the corresponding application is changed at the moment. Due to the difference of the running state of the camera application, the corresponding parameter recovery information is different. When the running state of the corresponding application is changed, the shooting parameters corresponding to different running states and needing to be restored to the preset initial values also need to be restored. Therefore, after determining that the running state of the camera application is the current running state in step S402, the electronic device needs to detect in real time whether the running state of the camera application is changed, that is, whether the running state of the camera application is switched to the background running state or to the running ending state.

In some embodiments, the operational state of the camera application may be indicative of different operational states by different values of the operational parameter. If the value of the operation parameter is 01, the operation state of the camera application is represented as a current operation state, if the value of the operation parameter is 10, the operation state of the camera application is represented as a background operation state, and if the value of the operation parameter is 11, the operation state of the camera application is represented as an operation ending state. The electronic device may determine whether the operational state of the camera application is switched by detecting the value of the operational parameter.

Step S407, when the running state of the camera application is switched to the background running state or the running state is ended, determining parameter recovery information of the camera application according to the running state of the camera application.

Specifically, when it is determined that the running state of the camera application is switched from the current running state to the background running state or the running state is finished, the running state is changed, and at this time, the electronic device needs to recover the parameter value of the relevant shooting parameter. At this time, the electronic device may determine, according to the running state of the machine application, the parameter recovery information corresponding to the running state.

For example, if the running state of the corresponding application is switched from the current running state to the background running state, the parameter recovery information of the camera application corresponding to the running state of the platform may be determined according to the running state of the platform.

The step S302 may be specifically performed, and is not described herein again.

And step S408, restoring the first target shooting parameter in the camera application to a preset initial value according to the parameter restoring information of the camera application.

The step S303 may be executed in detail, and is not described herein again.

As described in the above example, referring to the interface shown in fig. 8(2), when video shooting is finished, the camera application is in the current running state, and only the shooting zoom parameter is restored to 1 time, and for the 4K HDR control parameter and the filter parameter, the values are still the values selected by the user and are not changed. If the user has closed the camera application. At this time, the electronic device may detect that the operation state of the camera application is switched from the currently operating state to the state in which the operation is ended. The electronic device may further determine, in the pre-stored parameter recovery information, parameter recovery information corresponding to a state of ending operation of the camera application. The parameter recovery information corresponding to the operation-ended state includes filter parameters and shooting zoom parameters. The electronic device may determine the first target photographing parameter as a photographing zoom parameter polar filter parameter. The 4K HDR control parameter is determined as the third target photographing parameter. At this time, when the electronic device finishes shooting, the parameter value of the shooting zoom parameter is restored to a preset initial value, that is, to 1 time zoom, and the filter parameter is restored to the default filter LUT1, while the 4K HDR control parameter is still the value selected by the user and is not changed, refer to the interface shown in fig. 8 (2).

Step S409, when the running state of the camera is the running state of the background, determining whether the running state of the camera application is switched to the running end state.

Specifically, when the parameter recovery information corresponding to the background running state is different from the parameter recovery information corresponding to the running ending state, the electronic device may detect whether the running state of the camera application is switched to the running ending state in real time when the running state of the camera application is the background running state.

Step S410, when the running state of the camera application is switched to the running finishing state, determining parameter recovery information of the camera application according to the switched running state of the camera application.

The specific parameter step S407 is not described herein again.

And S411, restoring the first target shooting parameter in the camera application to a preset initial value according to the parameter restoring information of the camera application.

The step S303 may be executed in detail, and is not described herein again.

Referring to fig. 9, a schematic flow chart of another video shooting method provided in the embodiment of the present application is shown. The method is different from the embodiment shown in fig. 4, in that a step of the electronic device to capture a video image is added, as shown in fig. 9, which mainly includes the following steps.

Step S901, in response to a camera mode selection operation, determines a target camera mode.

In the embodiment of the present application, the camera mode refers to an operation mode of the camera, and may include a photographing mode, a recording mode, a professional mode, a movie mode, and the like. The user may send a camera mode selection operation to the electronic device after selecting a certain mode for capturing a video image. At this time, the electronic device may determine the target camera mode according to the received camera mode selection operation.

Further, the target camera mode is a movie mode. In the movie mode, the captured video is closer to the movie effect.

And step S902, responding to the shooting parameter setting operation, and setting the value of the second target shooting parameter applied by the camera according to the shooting parameter setting operation.

The shooting parameter setting operation carries a setting value of a second target shooting parameter. The second target shooting parameter is a shooting parameter whose parameter value is set by the user indicated by the shooting parameter setting operation.

Specifically, refer to step S401, which is not described herein again.

It should be noted that if the function of intelligently recommending the LUT filter is turned on in the electronic device, the electronic device needs to recommend the LUT filter according to the current shooting scene, and then the following steps S903 to S904 are executed. If the function of intelligently recommending the LUT filter is not started, the electronic equipment does not recommend the LUT filter according to the current shooting scene, and at this time, the steps S903-S904 are not executed any more, and the following steps S905-S909 are directly executed.

And step S903, determining a target LUT tone according to the acquired video image, and updating the parameter value of the filter parameter to the parameter value corresponding to the target LUT tone when the parameter value of the filter parameter is different from the parameter value corresponding to the target LUT tone.

Wherein the target LUT tone is a LUT tone recommended from the captured video image.

In the embodiment of the application, if the function of intelligently recommending the LUT filter is turned on, the electronic device may collect a video image through the camera, may perform scene recognition according to the collected video image, and further determine an LUT tone suitable for a current shooting scene according to the recognized scene, and determine the suitable LUT tone as the target LUT tone. And when the parameter value of the current filter parameter is different from the parameter value corresponding to the target LUT tone, the LUT filter used by the current camera is not the target LUT tone, and the parameter value of the current filter parameter is updated to the parameter value corresponding to the target LUT tone.

Further, when the electronic device just starts the shooting function of the video image, the parameter value of the current filter parameter is a preset initial value. At this time, if the electronic device determines the target LUT tone according to the acquired video image, and if the preset initial value of the filter parameter is not the parameter value corresponding to the target LUT tone, the filter parameter value needs to be updated to the parameter value corresponding to the target LUT tone.

Further, when the camera mode is the movie mode, the preset initial value of the filter parameter is a parameter value corresponding to the tone of the preset LUT. That is, when the movie mode shooting is entered, in order to more approximate the movie effect, the shot video image needs to be superimposed with an LUT filter.

And step S904, performing filter rendering processing on the video image according to the filter parameters.

In this embodiment of the application, after the filter parameter is set as the parameter value corresponding to the target LUT tone, the rendering process may be performed according to the video image corresponding to the target LUT tone, that is, the target LUT tone is superimposed on the captured video image.

Step S905, in response to the video shooting operation, shoots a video image.

In the embodiment of the application, after the user completes the corresponding shooting parameter setting in the target camera mode, the video shooting operation can be sent to the electronic equipment, and after the electronic equipment receives the video shooting operation, the electronic equipment can control devices such as a camera to shoot video images.

Step S906, in response to the shooting end operation, stops shooting the video image, and determines the running state of the camera application.

Specifically, refer to step S201, which is not described herein again.

Specifically, refer to step S411, which is not described herein again.

Illustratively, assume that a user desires the electronic device to take a video shot in movie mode. At this time, the electronic device may receive a camera mode selection operation of a movie mode sent by a user, the electronic device may determine the movie mode as a target camera mode, the electronic device starts the movie mode, after the movie mode is started, a filter parameter value of the electronic device is a parameter value corresponding to the LUT1, that is, in the movie mode, the LUT1 is used as an initial filter, and after the movie mode is started, a captured video image may automatically overlap a filter effect of the LUT 1. The user sets some shooting parameters in the movie mode, and supposing that the user turns on the HDR10 switch and turns on the IMAX switch, and the electronic device automatically turns on the intelligent filter recommendation function in the movie mode, that is, in the movie mode, the electronic device can determine a shooting scene according to a shot video image, and further can recommend an LUT filter suitable for the shooting scene. Based on this, the electronic device may receive a shooting parameter setting operation, where the second target shooting parameters carried in the shooting parameter setting operation are the HDR10 switch parameter and the IMAX switch parameter. And the setting value of the HDR10 switch parameter is a parameter value corresponding to turning on the HDR10 switch, and the setting value of the IMAX switch parameter is a parameter value corresponding to turning on the IMAX switch. The electronic device can set the HDR10 switch parameters and IMAX switch parameters of the camera application according to the shooting parameter setting operation. Moreover, the electronic device may collect a video image of a current shooting scene, and assume that, according to the collected video image, it determines that an LUT filter suitable for the current scene is LUT4, and the electronic device determines LUT4 as a target LUT hue, because a parameter value of a filter parameter is a parameter value corresponding to LUT1 in the movie mode and is different from a parameter value corresponding to the target LUT hue, at this time, the electronic device may update the parameter value of the filter parameter to a parameter value corresponding to LUT4, as shown in fig. 10.

The electronic device can take the video image after receiving the video shooting operation. The electronic device may perform LUT4 tone rendering processing on the captured video image according to the filter parameters, that is, superimpose LUT4 tone filters on the captured video image. And if the user needs to stop shooting, sending a shooting ending operation to the electronic equipment, and after receiving the shooting ending operation, the electronic equipment can stop shooting the video image and determine the running state of the current camera application. Assuming that the running state of the current camera application is a background running state, the electronic device determines parameter recovery information of the camera application according to the running state of the camera application. It is assumed that the parameter recovery information applied by the camera includes two parameters, namely a filter parameter and an IMAX switch parameter, and carries a parameter value corresponding to the filter parameter recovered to LUT1, and the IMAX switch is turned off. At this time, the electronic device may determine the filter parameter and the IMAX switch parameter as the first target shooting parameter according to the parameter recovery information applied by the camera, determine a preset initial value corresponding to the filter parameter and the IMAX switch parameter according to the parameter recovery information, and determine the HDR10 switch parameter as the third target shooting parameter. The electronic device may restore the first target shooting parameter to a preset initial value according to the parameter restoration information, that is, restore the filter parameter to a parameter value corresponding to the LUT1, set the IMAX switch parameter to a parameter value corresponding to the closed IMAX switch, and keep the HDR10 switch parameter unchanged from the parameter value corresponding to the opened HDR10 switch.

Referring to fig. 13, a schematic flow chart of another video shooting method provided in the embodiment of the present application is shown. In the embodiment of the present application, a target camera mode is taken as a movie mode, and an intelligent recommendation filter function is turned on as an example for explanation. The method can be applied to the software structure shown in fig. 11 and 12, as shown in fig. 13, which mainly includes the following steps.

S1301, the camera application of the electronic device enters a movie mode in response to the camera mode selection operation.

The user selects a camera mode for capturing the video image in the electronic device before capturing the video image, and the camera application determines the camera mode of the video image selected by the user as a target camera mode. In the embodiments of the present application, the target camera mode is taken as an example of the movie mode.

And S1302, responding to the shooting parameter setting operation, and sending the value of the second target shooting parameter to a corresponding module by the camera application of the electronic equipment according to the shooting parameter setting operation.

The shooting parameter setting operation carries a setting value of a second target shooting parameter. The second target shooting parameter is a shooting parameter whose parameter value is set by the user.

When the user needs to set the shooting parameters in the movie mode, the shooting parameter setting operation can be sent to the electronic device, and the electronic device carries the setting values of the second target shooting parameters. After receiving the shooting parameter setting operation, the camera application can set the corresponding shooting parameters in the movie mode according to the setting values of the second target shooting parameters in the camera application. In the embodiment of the present application, an example is described in which the user turns on the HDR10 function, that is, the second target shooting parameter is a parameter for turning on the HDR10 switch.
