Detailed Description

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, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be implemented in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The method, the apparatus, the electronic device, and the readable storage medium for outputting the multimedia file provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and application scenarios thereof.

In the related art, a user can beautify a shot object only through image optimization modes such as a filter of shooting software, a virtual background, or adding small stickers and the like. But cannot directly change the background image of the multimedia image on the photographed preview interface.

Similarly, if a user records a video, only some video special effects can be added through video recording software, and the background image cannot be directly changed on a recording interface for recording the video.

Therefore, whether the picture is taken or the video is recorded, if the background image needs to be replaced, the background image can be replaced only through later image processing, such as Photoshop software. However, the operation of the software is complex, so that the operation of the user is cumbersome, and the user experience is low.

Therefore, in order to solve the above-mentioned problems, embodiments of the present application provide a multimedia file output method, an apparatus, an electronic device, and a readable storage medium, which can meet a requirement that a user can adjust a background image in real time when outputting a target multimedia file such as an image or a video.

Fig. 1 is a flowchart illustrating a multimedia file output method according to an embodiment of the present application.

As shown in fig. 1, the multimedia file output method includes S110 to S140, which are explained in detail below:

s110, receiving a first input to a target preset control under the condition that the multimedia image is displayed.

Wherein the multimedia image comprises a target subject.

In some embodiments of the present application, the multimedia image may be a preview image displayed in a shooting preview interface, a preview video frame displayed in a video recording interface, or a photograph obtained after shooting.

For example, when a girl is photographed, a photographing preview image displayed on a screen of the electronic device may be a multimedia image; similarly, when recording a girl, the preview video frame in the video recording interface displayed on the screen of the electronic device during the recording process can also be a multimedia image.

In some embodiments, the first input may be a click input of the user or a long-press input, which is not limited herein. The target preset control is displayed on a display screen of the electronic equipment.

Taking an electronic device with a waterfall screen as an example, as shown in fig. 2, fig. 2 is a schematic interface diagram provided in the first embodiment of the present application. The electronic device in fig. 2 comprises a main display 21 and a secondary display 22, and a target preset control 23 is displayed on the secondary display 22. The target preset control may be in the form of an arrow as shown in fig. 2, or may be an identifier of another shape, where no limitation is made on the shape of the target preset control.

And S120, responding to the first input, and determining a target background based on a target background theme associated with the target preset control.

In some embodiments of the present application, the preset control may be associated with a background theme, for example, a background theme such as weather, a place, and the like, so that the target background may be determined in response to a first input of the target preset control by a user.

And S130, receiving a second input of the user.

In some embodiments, the second input may be a click input of the user or a long-press input, which is not limited herein.

And S140, responding to the second input, and outputting the target multimedia file.

Wherein the target multimedia file comprises a target subject and a target background.

In some embodiments of the present application, the user may perform a second input on the shooting key, and the electronic device may output the target multimedia file including the target subject and the target background after receiving the second input on the shooting key by the user.

In the following, by some embodiments, before S110, the multimedia file output method may further include a step of determining a target subject in the multimedia image, specifically as follows:

receiving a third input of the first object in the multimedia image by the user;

in response to a third input, calculating first depth information for the first object;

acquiring a second object meeting a first preset condition in the multimedia image;

wherein the first preset condition is associated with the first depth information;

the second is determined to be the target subject.

In the embodiment of the present application, as shown in fig. 3, fig. 3 is a schematic interface diagram provided in the second embodiment of the present application. The multimedia image as shown in fig. 3 includes a girl 31 and a ball 32. After the user performs the third input on the first object where the head of the girl 31 is located, and the electronic device receives the third input, the depth-of-field information of the head of the first object girl 31 is automatically calculated, and the first depth-of-field information is obtained.

Next, after determining the first depth information, the electronic device further obtains a second object satisfying a first preset condition in the multimedia image. The first preset condition may be that the depth of field is the same as the first depth of field, or that a difference between the first depth of field and the first depth of field information is smaller than a preset threshold. The preset threshold value may be set as required, and is not described herein again.

For example, with continued reference to fig. 3, after the user makes a third input on the head of the girl 31, the electronic device obtains a second object including the girl 31 and satisfying the first preset condition through the depth of field calculation.

In other embodiments, after determining the second object, the second object may also be identified by a boundary identifier.

In the embodiment of the application, through calculation of depth of field information of the first object by the user, the electronic device identifies people, animals or objects based on selection input of the user, and obtains a shooting subject and a corresponding background of the shooting subject, of which the user desires to change a background image.

In other embodiments of the present application, the user may also customize a shape by a tool customization function such as a brush, and the position and size may also be identified by the boundary identifier.

In further embodiments of the present application, before S110, the step of determining the target subject in the multimedia image included in the multimedia file output method may be as follows:

acquiring a second object meeting a second preset condition in the multimedia image based on the preset depth of field range;

wherein the second preset condition is associated with a preset depth of field range;

the second object is determined as the target subject.

In the embodiment of the present application, the camera component of the electronic device may be a depth camera based on a Time of Flight (TOF) scheme. Therefore, the electronic device can directly acquire the depth information of each object in the image. Therefore, when the target subject in the multimedia image is identified, the second object meeting the second preset condition can be obtained only within the preset depth range. The preset depth of field range may be set according to different scenes in the image, and no limitation is made to specific values of the preset depth of field range.

Referring to fig. 3, when the user records the video of the scene in which the girl 31 is playing the ball, the electronic device may directly acquire the depth-of-field information of the girl 31 and the depth-of-field information of the ball 32 because the electronic device may be based on the TOF scheme of the camera assembly, so that the electronic device may determine the girl 31 in the multimedia image as the second object when the depth-of-field information of the girl 31 satisfies the second preset condition. The second preset condition may be that the depth information is within a preset depth information range.

In some embodiments of the present application, the second object may also be identified by a boundary identifier.

In the embodiment of the application, the depth information of each object in the image can be automatically acquired through the TOF structure of the camera, so that the depth information of each object is further acquired, the electronic equipment can automatically identify people, animals or objects, and the use experience of a user is improved.

In other embodiments of the present application, if multiple second objects are included in the image

After identifying each second object in the image by the TOF structure of the camera, a plurality of second objects may be obtained. With continued reference to fig. 3, when video recording is performed by using a camera based on the TOF scheme, if the depth information of both the girl 31 and the ball 32 satisfies the second preset condition, the second object girl 31 and the second object ball 32 can be obtained. Thus, when determining the target subject, the user is also required to make a click or press input on the second object girl 31 or the second object ball 32, and then the electronic device will determine the target second object (girl 31 or ball 32) as the target subject.

In some embodiments of the present application, a multimedia file output method is applied to an electronic device having a first display area and a second display area. The first display area may be located on a front surface of the electronic device, and the second display area may be located on a side surface of the electronic device, for example, an electronic device having a waterfall screen, and the like.

When the target multimedia file is output by using the electronic device with the second display area, before the second object is determined as the target subject, the method further comprises the following steps:

receiving a fourth input that the user drags the second object from the first display area to the second display area;

next, when the target subject is to be determined, the electronic device may determine the second object as the target subject in response to a fourth input.

In an embodiment of the present application, as shown in fig. 4, fig. 4 is a schematic interface diagram provided in the third embodiment of the present application. The second object 41 is displayed in the electronic device shown in fig. 4, and when the target subject is determined, the user needs to drag the second object 41 into the second display area 42. The electronic device may determine the second object as the target subject upon receiving a fourth input that the user drags the second object 41 to the second display area 42. Wherein the determined target subject can be identified by the boundary identifier 43. However, the boundary identifier may be in the form of a virtual line or in other forms, and the representation form of the boundary identifier is not limited to any form.

In some embodiments, after identifying each second object in the image through the TOF structure of the camera to obtain a plurality of second objects, the user may further merge the plurality of second objects, and the merging of the second objects may be specifically implemented through the following steps:

receiving a first target input of a user to at least two second objects;

in response to the first target input, a second object associated with the target input is merged into one second object.

The first target input may be a click input or a press input, a drag input, or the like.

As an example, as shown in fig. 5, fig. 5 is a schematic interface diagram provided in the fourth embodiment of the present application. The user can simultaneously double-click at least two second objects 51 by two or more fingers and drag the at least two objects to the same position; it is also possible that the user drags one second object to the location of another second object. At this time, the electronic device fuses the second object dragged to the same position into one second object. And a separator exists between two objects in the fused second object, and a user can release the fused second object to restore the fused second object to the object before fusion by long-pressing and dragging the fused second object at a preset position of a screen.

In the embodiment of the application, the user can independently merge the second object according to the own use requirement, so that the second object meeting the own use requirement of the user is obtained, and the use experience of the user is improved.

In other embodiments of the present application, the user may not only merge the second object but also split the second object before receiving a fourth input that the user drags the second object to the second display region of the screen. For example, the segmentation of the second object may be achieved by:

receiving a sixth input of the second object from the user;

in response to a sixth input, dividing the second object into a plurality of sub-objects according to the sliding track of the sixth input;

in this way, when the target subject is determined, a fourth input of the user dragging the target sub-object of the plurality of sub-objects from the first display area to the second display area may be received, and the target sub-object may be determined as the target subject in response to the fourth input.

As an example, as shown in fig. 6, fig. 6 is a schematic interface diagram provided in a fifth embodiment of the present application. The sixth input may be a sliding input, and the user may activate the edge delimiter of the second object by clicking or double-clicking the second object, so that the user may pass the sixth input, so that the electronic device may divide the second object into a plurality of sub-objects according to the sliding trajectory of the sixth input.

In the embodiment of the application, the user can also segment the second object according to the own use requirement, the electronic device identifies the sliding input of the user and automatically adsorbs the second object according to the acquired depth information boundary, so that the segmentation accuracy is higher, the second object meeting the own use requirement of the user can be obtained, and the use experience of the user is improved.

In some embodiments of the present application, before S110, an association relationship between a preset control and a background theme may also be established, specifically including the following steps:

receiving eleventh input of a user to a preset control;

in response to an eleventh input, an association between the preset control and the background theme is determined.

The eleventh input may be a click input or a long-press input, and is not limited herein.

As an example, the user may establish an association relationship between the preset control and the background theme by long pressing the preset control. For example, a preset control can be associated with weather, a preset control can be associated with a location, and so forth.

In addition, the user can also customize the association relationship between each preset control and the background theme in a self-defining mode.

In the embodiment of the application, the user can customize the incidence relation between the preset control and the background theme, so that the target background of the multimedia file can be directly obtained by the user through inputting the preset control in the later period, the operation complexity of the user is reduced, and the use experience of the user is improved.

In some embodiments of the present application, in order to better meet the use requirements of the user for the background image in different scenes, further embodiments of the present invention further provide a multimedia file output method applicable to an electronic device, as specifically shown in fig. 7.

Fig. 7 is a schematic flowchart of a multimedia file output method according to another embodiment of the present application, where the method includes:

s710, receiving a first input of a target preset control under the condition that a multimedia image is displayed;

the step of S710 is the same as S110 shown in fig. 1, and is not repeated herein.

S720, determining a first image based on the target background theme;

s730, acquiring pose information of the electronic equipment;

in some embodiments of the present application, the pose information may include: information such as the inclination angle of the electronic device, angle information from the light source of the electronic device, and distance. The electronic equipment can acquire the pose information of the electronic equipment through gravity and a gyroscope.

S740, adjusting scene information of the first image based on the corresponding relation between the pose information and the scene information, and taking the adjusted first image as a target background;

in some embodiments of the present application, the target context theme is a context theme associated with the target preset control. For example, if the target preset control is associated with weather, the target background theme is weather. The image under the subject background may be an image of a rainy day, an image of a snowy day, an image of a cloudy day, an image of haze, or the like.

S750, receiving a second input of the user;

and S760, responding to the second input, and outputting the target multimedia file.

In the embodiment of the application, a user can adjust the scene information of the first image by adjusting the pose information of the electronic device, so that the user can adjust the scene information of the first image in real time to obtain a target background which meets the use requirements of the user.

The following describes some embodiments in detail how S740 can be implemented.

In some embodiments, the user moves the electronic device horizontally, and may display the light and shadow scene information of the target at different lighting angles according to the angle information;

in some embodiments, a user moves the electronic device upward, and may determine whether the current shooting scene is an indoor or outdoor scene through luminance information or an artificial intelligence scene, so as to display or switch different sky or building upper scene information such as day/night/rainy and snowy days;

in some embodiments, the user moves the electronic device downward, and may display ground information to display corresponding different scene information;

in some embodiments, the user may customize an application or a keyword to link the horizontal direction rotation switching, for example, input a "weather" keyword or link a weather application, the user turns the terminal to switch the background to the background in different weather, and at the same time, the link place may switch the background to the background in the local weather, by continuing to turn the electronic device, the user may change the weather in different time points, by turning the electronic device fast, by turning the electronic device slow, the user may change the weather in different days, or by turning the electronic device slow, or by switching the first image to the background picture associated with the target background theme on the network.

In other embodiments, as shown in fig. 8, fig. 8 is a schematic interface diagram provided in the seventh embodiment of the present application. The multimedia image may further have axis-of-induction marks 81 and 82 displayed thereon for prompting a user to adjust scene information of the first image by rotating the electronic device.

For example: it may be that the upper and lower flips represent changes in time period of a quarter, and the left and right flips represent changes in time unit, so that the longer and shorter time changes are controlled by the upper and lower flips and the left and right flips, respectively.

For another example, the place may be turned upside down, and the climate may be turned upside down. The user can turn over from top to bottom to switch over the geographical positions with different longitudes and latitudes, and the climate change is represented by turning over from side to side. (e.g., switching to a different latitude shows a north-south pole or a climate change of a land ocean).

And the position change route can be quickly defined by turning the link to the map upside down.

In order to increase user operability, in some embodiments of the present application, the user may also adjust the second object through the adjustment control before determining the second object as the target subject. The method specifically comprises the following steps:

receiving a fifth input of the second object by the user;

in response to a fifth input, displaying an adjustment control associated with the second phase; the adjusting control comprises: a first control; the first control is used to resize the second object and/or position the second object on the multimedia image.

In some embodiments of the present application, the fifth input may be a long-press input or a click input, which is not limited herein.

As shown in fig. 9, fig. 9 is a schematic interface diagram provided in the eighth embodiment of the present application. And after the user presses the second object for a long time, the adjusting control corresponding to the second object can be displayed. Among them, the first control 91 in the shape of an arrow as shown in fig. 9 may be included in the adjustment control. The user can press and drag the first control 91 to adjust the local position; the size of the whole body can be adjusted by double-clicking and holding the dragging first control 91; the two fingers hold down the border symbol at two locations simultaneously and drag the location where the second object can be dragged, and so on.

Further, in other embodiments, the adjustment controls may further include a second control 92 and a third control 93 as shown in FIG. 9. The second control 92 is used to cancel the previous operation of the user, or reset the second object to an initial state without adjustment. The third control 93 is used to deselect this selection and to re-determine the target subject based on a third input by the user.

In the embodiment of the application, the adjustment control is displayed, so that a user can adjust the second object through inputting the adjustment control, and the second object which meets the requirements of the user better is obtained.

In order to enable the user to realize the effect of video clipping during the video recording process, other embodiments of the present application further provide an output method of the target multimedia file, and a time adjustment axis can be displayed on the video recording interface, as shown in fig. 10.

Fig. 10 is a flowchart illustrating a multimedia file output method according to another embodiment of the present application, where the multimedia file output method includes:
