It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. 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 video recording method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart of a video recording method applied to an electronic device according to an embodiment of the present disclosure. As shown in fig. 1, the method may include the steps of:
step 11: and acquiring a plurality of focus tracking objects of the video to be recorded.
Alternatively, the plurality of focus tracking objects may include at least two focus tracking objects. In this step, the electronic device may obtain the focus tracking object of the video to be recorded according to a pre-input condition of the selected focus tracking object, such as a name, an action, and/or a location of the focus tracking object; the focus tracking object of the video to be recorded can also be acquired according to user input, such as clicking operation, sliding operation and the like of the focus tracking object on a video preview interface by a user or an object identifier selected by the user. In this step, the electronic device acquires information of a plurality of focus-following objects of the video to be recorded.
It is understood that prior to this step 11, the electronic device may receive a video recording instruction from the user to initiate video recording. For example, after the video recording function in the electronic device is started, the user may click the recording button to input a video recording command, and accordingly, the electronic device receives the video recording command.
In a specific example, the video recording process in the present application may be performed in a "movie shooting mode". After the video recording function in the electronic equipment is started, the user can click the 'movie shooting mirror' button, so that the electronic equipment enters a movie shooting mirror mode.
Step 12: displaying a corresponding plurality of focus chasing frames of a plurality of focus chasing objects on a video preview interface.
In this embodiment, the focus tracking frame may be a fixed size, or may be determined based on the size of the corresponding focus tracking object. For example, taking the focus tracking object as the person as an example, the corresponding focus tracking frame may be determined based on the completely covered person as shown in fig. 5.
Optionally, the focus tracking frame in the present application may be a square frame, as shown in fig. 2 or fig. 3, or may be a frame with another shape, such as a circular frame. The focus tracking frame in the present application may be an entity frame, that is, a frame that can be displayed in a video preview interface, as shown in fig. 2 or fig. 3, or may be a virtual frame, for example, a focus tracking frame that is embodied by covering other areas.
Step 13: and recording the video to be recorded according to the positions of the plurality of focus tracking frames.
In this embodiment, when a video is recorded, simultaneous focus tracking may be performed on a plurality of corresponding focus tracking objects according to positions of a plurality of focus tracking frames, that is, a video is recorded by using a picture selected by the plurality of focus tracking frames as a recording content, so that the plurality of focus tracking objects are highlighted.
According to the video recording method, when the video is recorded, the multiple focus following objects of the video to be recorded can be obtained, the multiple focus following frames corresponding to the multiple focus following objects are displayed on the video preview interface, and the video to be recorded is recorded based on the positions of the multiple focus following frames. Therefore, tracking of a plurality of shot objects can be achieved when videos are recorded, and recording effects are improved.
In the embodiment of the application, in order to facilitate a user to know a recording effect, in the process of recording a video, a shielding object may be used to cover other areas except for multiple focus tracking frames in a video preview interface, so as to display the recording content when multiple focus tracking objects are focused simultaneously in the video preview interface. Optionally, the shade is a translucent black mask, for example.
In the embodiment of the application, the electronic device can acquire a plurality of focus-following objects of the video to be recorded according to the input of the user. Optionally, step 11 may include:
receiving a first input of a user on a video preview interface;
in response to the first input, a plurality of focus following objects of the video to be recorded are acquired.
For example, the first input may be a click operation, a slide operation, or the like of the user on the focus tracking object on the video preview interface, or may also be a selection operation of the user on an object identifier displayed on the video preview interface. For example, if a portrait identifier and a pet identifier are displayed on the video preview interface, after the user selects the portrait identifier, it may be determined that an object corresponding to the portrait identifier is a focus-following object; or after the user selects the pet identifier, the object corresponding to the pet identifier can be determined to be the focus tracking object. Therefore, the required focus tracking object can be accurately determined by means of user input, and the video recording effect is guaranteed.
It should be noted that, in the embodiment of the present application, in addition to all the required focus following objects that can be selected by the user, after a certain focus following object is determined, other focus following objects may be automatically identified according to the characteristic information of the focus following object, such as motion, sound, scene, and the like, so as to perform synchronous focus following.
Optionally, the acquiring the multiple focus-following objects in step 11 may include:
acquiring a first focus tracking object; for example, the first focus tracking object may be determined by an input operation of a user;
determining a second focus tracking object according to the characteristic information of the first focus tracking object; wherein the plurality of focus-following objects include a first focus-following object and a second focus-following object, that is, the second focus-following object is a focus-following object other than the first focus-following object in the plurality of focus-following objects.
For example, taking an example in which the plurality of focused objects include the focused person 1 and the focused person 2, after the focused person 1 is specified, the focused person 2 can be specified based on the direction in which the focused person 1 faces and/or the name of the person who focused the person 1.
Therefore, other focus tracking objects are further determined by means of the determined focus tracking objects, the relevance between the focus tracking objects which are simultaneously focused can be ensured, and the video recording effect is improved.
In the embodiment of the application, in order to switch the lens more accurately, the focus tracking frames can be combined and separated according to actual requirements. Optionally, the recording of the video to be recorded according to the multiple focus tracking frames may include:
combining the multiple focus tracking frames into at least one target focus tracking frame;
and recording the video to be recorded according to the position of the at least one target focus tracking frame.
Further, after combining the multiple focus tracking frames into at least one target focus tracking frame, the electronic device may further separate the at least one target focus tracking frame into multiple focus tracking frames, and record the video to be recorded according to the positions of the separated multiple focus tracking frames. And for the separated focus tracking frames, there can be one focus tracking object in each focus tracking frame.
In this way, by means of merging and separating the focus-following frames, the effect of corresponding focus-following objects when the focus-following objects are together can be obtained after merging the focus-following frames, and a single focus-following object can be close-up after separating the focus-following frames, so that a better recording effect is realized.
Optionally, in the embodiments of the present application, the following ways, which are detailed below, may be adopted, but not limited to, to merge and separate the focus tracking frames.
In a first mode
In this manner, the electronic device may automatically merge corresponding focus tracking frames when multiple focus tracking objects are close, and automatically separate focus tracking frames when multiple focus tracking objects are far away. For example, taking the tracking object a and the tracking object B as an example, when the tracking object a and the tracking object B are close to each other, the tracking frame of the tracking object a and the tracking frame of the tracking object B may be merged into one frame, for example, as the tracking frame m. Further, when the tracking object a and the tracking object B are distant, the tracking frame m may be separated into two, that is, the tracking frame of the tracking object a and the tracking frame of the tracking object B.
As an example, the close proximity of the above-described focus following object a and focus following object B means: the image areas occupied by the object a and the object B to be focused, that is, the sum of the image areas occupied by the focus tracking frame of the object a and the focus tracking frame of the object B to be focused in the case of non-merging is in a certain proportion of the image area occupied by the merged focus tracking frame. The ratio can be set according to the screen content or user operation.
As an example, the above-described focus following object a and focus following object B being far away means: the image area occupied by the tracking object a and the tracking object B, that is, the sum of the image areas occupied by the tracking frame of the tracking object a and the tracking frame of the tracking object B in the case of non-merging, is smaller than a certain ratio in the image area occupied by the merged tracking frame. The ratio can be set according to the screen content or user operation.
Optionally, the merging the plurality of focus chase frames into the at least one target focus chase frame may include: when the ratio of the sum of the image areas occupied by the plurality of focus-following frames to the first image area is larger than a first threshold, the electronic equipment merges the plurality of focus-following frames into one target focus-following frame. The first image area is an image area occupied by the plurality of focus tracking frames after being combined. The first threshold value may be set according to screen content or user operation.
Further, after combining the multiple focus tracking frames into one target focus tracking frame, the electronic device may further separate the one target focus tracking frame into multiple focus tracking frames when a ratio of a sum of image areas occupied by the multiple focus tracking frames to the first image area is smaller than a second threshold, and record the video to be recorded according to the separated multiple focus tracking frames. The second threshold may be set according to screen content or user operation. In particular, to avoid the occurrence of flicker, the second threshold is lower than the first threshold.
Therefore, in the video recording process, the combination and separation of the focus tracking frames can be automatically realized by means of preset conditions, so that the recording effect is improved.
For example, taking as an example that the plurality of focus following frames include a focus following frame of a focus following object a and a focus following frame of a focus following object B, it is assumed that the sum of image areas occupied by the focus following frame of the focus following object a and the focus following frame of the focus following object B is 52cm 2 The combined focus-following frame occupies an image area of 86cm 2 If the first threshold value is 60%, the ratio of 52 to 86 is greater than 60%, and therefore the condition for focusing frame merging is satisfied, and the focusing frame of focusing object a and the focusing frame of focusing object B can be merged into one target focusing frame.
Further, after merging into one target focus tracking frame, through the distancing of the focus tracking object a and the focus tracking object B, it is assumed that the focus tracking frame and the focus tracking pair of the focus tracking object a are pairedThe sum of the image areas occupied by the focus tracking frames of the elephant B is 44cm 2 The combined focus-following frame occupies an image area of 86cm 2 If the second threshold value is 55%, the ratio of 44 to 86 is less than 55%, and therefore the condition for separating the tracking frames is satisfied, and the one target tracking frame can be separated into the tracking frame for tracking object a and the tracking frame for tracking object B, and video recording can be continued from the separated tracking frames.
Mode two
In the second mode, the electronic device can realize the merging and the separation of the focus tracking frames according to the user input. The user input for the chase combining may include, but is not limited to, a two-finger pinch operation, a multi-finger (three-finger or more) pinch operation, and the like of the user, among others. User input for chase box separation may include, but is not limited to, a user's two-finger expansion operation, a multi-finger (three or more finger) expansion operation, and the like.
Optionally, the merging the plurality of focus chase frames into the at least one target focus chase frame may include: the electronic device receives a second input of the video preview interface from the user and merges the plurality of focus chasing frames into at least one target focus chasing frame in response to the second input. Wherein the second input is, for example: the user performs a double-finger pinch operation, a multi-finger pinch operation, and the like for a plurality of focus chasing frames on the video preview interface.
Further, after combining the multiple focus tracking frames into one target focus tracking frame, the electronic device may further receive a third input of the user to the video preview interface, in response to the third input, separate at least one target focus tracking frame into the multiple focus tracking frames, and record the video to be recorded according to the separated multiple focus tracking frames. Wherein the third input is, for example: and the user performs double-finger expansion operation, multi-finger expansion operation and the like on the target focus tracking frame on the video preview interface.
Therefore, in the process of recording the video, the combination and separation of the specific focus tracking frames can be realized by means of user input, so that the recording effect is improved.
The present application will now be described in detail with reference to the following examples and accompanying drawings.

S4: when the close proximity of the tracking object a and the tracking object B satisfies the condition for tracking frame merging, as shown in fig. 6, the tracking frame of the tracking object a and the tracking frame of the tracking object B may be merged into one tracking frame, and video recording may be performed based on the position of the merged tracking frame.
S5: when the tracking object a and the tracking object B are far from each other and the condition for tracking frame separation is satisfied, as shown in fig. 7, the combined tracking frame may be separated into the tracking frame of the tracking object a and the tracking frame of the tracking object B, and video recording may be performed based on the separated tracking frames.
