It should be noted that the first video image is an image acquired by the first camera in real time, and the second video image is an image acquired by the second camera in real time. In this way, the user can view the real-time captured image through the first preview window and the second preview window.

Optionally, the target area may be an area where the target object is located, or an area that is a preset distance away from the area where the target object is located, for example, when the target object is a hand, the area where the target object is located may be an area where the hand is located, or an area that is a preset distance away from the palm.

Further, in the embodiment of the present application, obtaining the target area may include the following two possible implementation manners:

a first possible implementation:

optionally, before the step 101, the video recording method provided in this embodiment may further include the following steps 103 to 106. Accordingly, step 101 is implemented by step 101A described below.

Step 103, the video recording device displays a first preview window and a second preview window in the shooting preview interface.

Optionally, for displaying the first preview window and the second preview window, the following 2 possible cases may be included:

(1) and the first preview window and the second preview window are displayed in a split screen mode.

(2) And displaying a second preview window on the first preview window in an overlapping manner. The display size of the second preview window is smaller than that of the first preview window, for example, in a picture-in-picture manner.

Optionally, in a case that at least two preview windows are displayed, a user may first trigger to select one preview window from the at least two preview windows as a main preview window according to actual needs, and then select a target object from a screen of the main preview window. For example, after the step 103, the video recording method provided in the embodiment of the present application may further include the following steps 103A to 103B.

Step 103A, the video recording apparatus receives an input to the first preview window.

Step 103B, the video recording apparatus sets the first preview window as the main preview window in response to the input.

Optionally, in this embodiment of the present application, the main preview window is a window in the preview interface for displaying the main preview image. And the display size of the main preview window is larger than that of other preview windows.

It is understood that, in the case that the first preview window is a non-main preview window, the above step 103A and step 103B may be executed; in the case where the first preview window is already the main preview window, the above-described step 103A and step 103B need not be performed. The method is determined according to actual use conditions, and the method is not limited in the embodiment of the application.

Step 104, the video recording device receives a first input of the target object in the first preview window from the user.

Alternatively, the first input may be: the click input of the target object by the user, or the voice instruction input by the user, or the specific gesture input by the user may be specifically determined according to the actual use requirement, which is not limited in the embodiment of the present application.

Illustratively, the specific gesture in the embodiment of the present application may be any one of a single-click gesture, a slide gesture, a drag gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture; the click input in the embodiment of the application can be click input, double-click input, click input of any number of times and the like, and can also be long-time press input or short-time press input.

Optionally, the target object is determined from an input position of the first input in the first video image.

Illustratively, the first video image is assumed to be a human image. The first input is input by clicking a palm in the character image, namely the target object is the palm; assuming that the first video image is a flower image, the first input is an input of clicking a flower pistil in the flower image, i.e. the target object is a flower pistil.

Step 105, the video recording device responds to the first input to obtain the target area.

And 106, the video recording device receives a second input of the user to the second preview window.

Optionally, the second input may be: the click input of the user to the second preview window, or the voice instruction input by the user, or the specific gesture input by the user may be specifically determined according to the actual use requirement, which is not limited in the embodiment of the present application.

Step 101A, the video recording apparatus displays the second preview window in the target area in response to the second input.

It can be understood that, in the embodiment of the application, when the first preview window and the second preview window are displayed in the shooting preview interface, the target area is triggered and obtained by the user through an input to the first preview window; and then triggering to display the second preview window in the target area through another input to the second preview window, so that a user can select the target area according to actual requirements, and the second preview window is displayed in the target area of the shooting preview interface through the electronic equipment, so that the effect of the recorded video is observed in advance.

A second possible implementation:

optionally, before the step 101, the video recording method provided in this embodiment of the present application may further include the following step 107 and step 108.

And step 107, the video recording device displays a first preview window and a second preview window in the shooting preview interface.

Optionally, for the description of displaying the first preview window and the second preview window, reference may be made to the related description in the first possible implementation manner in the foregoing embodiment, and details of this description are not repeated in this embodiment of the application.

And 108, under the condition that the target object in the first preview window meets a first preset condition, the video recording device acquires a region corresponding to the target object to obtain a target region.

Optionally, the first preset condition may include any one of: the action of the target object accords with the preset action, the gesture of the target object accords with the preset gesture, and the target object is a preset specific object.

It can be understood that, in the embodiment of the present application, the target area may be determined according to whether the target object meets the first preset condition, so that the second preview window is automatically displayed in the target area of the shooting preview interface through the electronic device, and the effect of the recorded video is viewed in advance.

Alternatively, the target object may be an object displayed in an arbitrary area in the first video image. For example, in the case where the first video image is a human image, the target object may be a palm, a face, or an arm; for another example, in the case where the first video image is a landscape image, the target object may be a flower, a butterfly, a branch, or the like.

Alternatively, the number of target objects may be one or more.

Specifically, when the number of the target objects is one, the number of the target areas corresponding to the target objects in the first preview window is also one; when the number of the target objects is plural, the target areas corresponding to the target objects in the first preview window are also plural.

Optionally, the target area may include a first target area and a second target area, and the target object may include a first target object and a second target object, where the first target area is an area corresponding to the first target object, and the second target area is an area corresponding to the second target object. Accordingly, the above step 101 is realized by the following step 101B or the following step 101C.

Step 101B, the video recording apparatus displays a second preview window in the first target area, and displays a third preview window in the second target area.

And the display contents of the third preview window and the second preview window are the same.

It should be noted that, in this embodiment of the application, when the electronic device includes only the first camera and the second camera, if the target object includes the first target object and the second target object, the electronic device may copy the second video image captured by the second camera, display the second video image in the second preview window, and display the copied second video image in the third preview window.

101C, the video recording device displays the second preview window in the first target area, and displays the fourth preview window in the second target area.

And the fourth preview window is used for displaying a third video image acquired by a third camera.

It should be noted that, in this embodiment of the application, when the electronic device includes a third camera except for the first camera and the second camera, if the target object includes the first target object and the second target object, the second preview window and the fourth preview window display video images captured by different cameras.

It is to be understood that, in the embodiment of the present application, in the case where the target area includes the first target area and the second target area, and the target object includes the first target object and the second target object, in a possible case, the display contents in the preview windows displayed in the first target area and the second target area are the same; in another possible case, the display contents in the preview windows displayed in the first target area and the second target area are different. Therefore, as the user can trigger the target areas corresponding to different target objects to display the same or different images, videos with different contents can be obtained so as to meet different requirements of the user.

Alternatively, in a case where the target object is in a motion state, the second preview window may move following the movement of the target object. Illustratively, step 101 is implemented by step 101D described below.

In step 101D, when the target object moves to the first position, the video recording apparatus synchronously moves the second preview window to the first position.

Optionally, the first position is a position of the target object corresponding to the first video image acquired by the first camera in real time when the target object is in a motion state.

Illustratively, the first position is a corresponding position of the target object in the first video image captured by the first camera after the target object stops moving.

It should be noted that, since the first position is the position of the target object, the target area corresponds to the first position, that is, the target area is the area where the first position is located, or the target area is an area that is away from the area where the first position is located by a preset distance.

It can be understood that, since the video recording apparatus can synchronously move the second preview window to the first position when the target object moves to the first position, the electronic device can display the second preview window on the shooting preview interface to follow the video image of the target object in real time during the movement of the target object, so that the user sees that the second video image always moves along with the movement of the target object. Therefore, the interestingness of shooting videos by the cameras is improved.

And 102, the video recording device obtains a target video according to the first video image and the second video image.

Alternatively, the above S102 may be implemented by the following S102A and step 102B.

And 102A, the video device performs image fusion on the first video image and the second video image to obtain a target video image.

Specifically, the "image fusion of the first video image and the second video image" specifically means: and fusing the second video image in the target area of the first video image.

And step 102B, the video recording device carries out video synthesis on the target video image to obtain a target video.

Illustratively, the video recording device is a mobile phone. Assuming that the mobile phone opens the front camera, the rear main camera and the rear wide-angle camera, as shown in (a) in fig. 2, the mobile phone displays a video image captured by the front camera in a first preview window 01 of a shooting preview interface: a person image; and displaying a video image acquired by a rear main camera in a second preview window 02 of the shooting preview interface: apple image to and the video image that the third preview window 03 at shooting preview interface shows rearmounted wide angle camera and gathers: an image of a building. After the user clicks on the left and right palms (i.e., target objects) of the person in the first preview window 01, the area 04 (i.e., first target area) and the area 05 (i.e., second target area) as shown in fig. 2 (a) are obtained. Finally, the user can click on the second preview window 02 and the third preview window 03, respectively. After the mobile phone receives the click input of the user, it may respond to the click input, as shown in (b) of fig. 2, the mobile phone displays a second preview window 02 in an area 04 of the photographing preview interface and displays a third preview window 03 in an area 05, that is, the user may see a preview image of the effect of holding an apple in the palm of the left hand and suspending a building in the palm of the right hand. Therefore, a video with different objects placed on the left palm and the right palm is obtained according to the person image, the apple image and the building image.

When images are respectively collected through two cameras of electronic equipment, because another preview window can be displayed in a target area in one preview window of a shooting preview interface, a target video is obtained according to a video image displayed by the preview window and a video image displayed by the other preview window, when a user plays the target video, the user can watch a video picture of another video displayed in the target area of the video, and the video content shot by the video recording method provided by the embodiment of the application is more interesting. In addition, the interest of multi-shot video shooting can be improved, the user does not need to perform post editing, and the operation is simple.

Optionally, after step 101, the video recording method provided in this embodiment may further include step 109.

And step 109, under the condition that the target object meets the second preset condition, the video recording device cancels the display of the second preview window in the target area.

Optionally, the second preset condition may include at least one of the following: the gesture of the target object is matched with the first preset gesture, and the target object is in a first preset state.

Illustratively, the first preset gesture may include any one of: a scissor hand gesture, a fist making gesture, and an ok gesture.

Optionally, after step 109, the video recording method provided in this embodiment of the present application may further include: and keeping displaying the first preview window on the shooting preview interface. Therefore, the user can shoot the image collected by the first camera in the preview interface.

Illustratively, the first preset state may include any one of the following: a moving state, a stationary state.

Illustratively, the target object is taken as a hand. When the finger of the user is detected to be more than the scissor hand gesture, the second preview window is cancelled and the first preview window is kept displayed in the shooting preview interface; and when the position of the hand of the user is detected to be changed, namely the hand of the user is in a motion state, canceling the display of the second preview window, and keeping displaying the first preview window in the shooting preview interface.

Optionally, after step 109, the video recording method provided in this embodiment may further include step 110.

And 110, displaying a second preview window in the target area by the video recording device under the condition that the target object meets a third preset condition.

Optionally, in this embodiment of the application, the second preset gesture is different from the first preset gesture, and the second preset state is different from the first preset state. For the detailed description of the second preset gesture and the second preset state, reference may be specifically made to the description of the first preset gesture and the first preset state in the above implementation, and details of this embodiment are not described again.

Optionally, after step 110, the video recording method provided in this embodiment of the present application may further include: and keeping displaying the first preview window on the shooting preview interface. In this way, the user can shoot the image which is rich in content and is seen in the preview interface.
