It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein and that references to "first", "second", etc. to distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The video frame rate adjustment method provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of a video frame rate adjustment method provided by an embodiment of the present application. The video frame rate adjustment method is applied to an electronic device, that is, the steps in the video frame rate adjustment method are executed by the electronic device.

Wherein, the video frame rate adjustment method may include:

Step 101: In the case of recording video through a target camera, obtain target parameters for adjusting the video frame rate (ie, the recording frame rate) of the target camera.

In the embodiment of the present application, the target parameters may include: a first moving speed of the target camera, or a change state of a distance between the electronic device and the target camera. Wherein, the distance change state mentioned here may include: the distance becomes smaller and the distance becomes larger.

In the case where the target parameter includes the first moving speed of the target camera, the target camera and the electronic device may be set separately, or the target camera may be set on the electronic device. In the case that the target camera is separated from the electronic device, the target camera can be a detachable camera on the electronic device, that is, a separate camera, or an external camera connected to the electronic device. In this case, the first A moving speed may be relative to the ground or relative to the electronic device. In the case where the target camera is set on the electronic device, the target camera can be a detachable camera on the electronic device, or an external camera on the electronic device, or a non-detachable camera on the electronic device. In this case, the target The first moving speed of the camera is the moving speed relative to the ground, that is, the moving speed of the electronic device relative to the ground.

In the case where the target parameter includes the distance change state between the electronic device and the target camera, the electronic device and the target camera are set separately, but a communication connection is established between the electronic device and the target camera. In this case, the target camera may be a detachable camera on the electronic device, or may be an external camera connected to the electronic device, so that the target camera and the electronic device may be separately set.

Step 102: Adjust the recording frame rate of the target camera according to the target parameters.

In the embodiment of the present application, the electronic device can adjust the video frame rate of the target camera according to the target parameters, such as adjusting the video frame rate of the target camera according to the moving speed of the target camera (that is, the first moving speed), or according to the target camera and the electronic device. The distance change state between them adjusts the recording frame rate of the target camera, so that during the video recording process, the dynamic adjustment of the recording frame rate can be performed, thereby obtaining videos with different recording frame rates, compared to the prior art The post-editing method, the method provided by the embodiment of this application is simpler and more convenient.

In order to better understand how the embodiment of the present application adjusts the video frame rate of the target camera according to the target parameters, a further explanation will be given below.

As an optional embodiment, when the target parameter includes the first moving speed of the target camera, step 102: adjusting the video frame rate according to the target parameter may include:

Step A1: Determine the first video frame rate corresponding to the first motion speed.

Step A2: If the current recording frame rate is not the first recording frame rate, adjust the recording frame rate to the first recording frame rate.

Among them, there is a positive correlation between the moving speed of the target camera and the corresponding video frame rate, that is, the higher the moving speed of the target camera, the larger the corresponding video frame rate; conversely, the lower the moving speed of the target camera, the corresponding The video frame rate is lower.

When there is relative motion between the camera and the scene being shot, motion blur may occur. For example, when shooting a video through the camera on a mobile phone, if the phone moves fast, the relative motion speed between the camera and the scene being shot It may become larger, resulting in motion blur, and the greater the relative motion speed, the more serious the motion blur problem may be, and the increase of the video frame rate can improve the motion blur problem to a certain extent, and when shooting motion, the camera and the subject The relative motion speed between the shooting scenes is generally not fixed, so in the motion shooting scene, in the prior art, it is generally first to shoot multiple videos with different frame rates, and then through post-production video editing, there will be no motion Stitching video clips with less blur issues or motion blur issues together to get a video with higher image quality can be cumbersome. Even though some special shooting equipment such as sports cameras support the function of adjusting the video frame rate during video shooting, it is still necessary to manually switch the video frame rate through the control button on the device, which requires high accuracy in the operation of the adjustment timing, but in When shooting in high-speed motion, it is difficult to capture the point where the frame rate is most needed to switch to perform the switching operation of the shooting frame rate.

The embodiment of the present application provides an implementation manner in which a recording frame rate can be adjusted according to a moving speed of a target camera used to record a video, so as to obtain a recorded video with higher image quality. This implementation method can dynamically adjust the video frame rate according to the camera’s motion speed during motion shooting. The higher the camera’s motion speed, the higher the video frame rate, thereby overcoming the problem of motion blur to a certain extent. In addition, This implementation method can automatically determine the adjustment timing of the video frame rate according to the change of the camera movement speed. Compared with the manual adjustment method, the adjustment timing is more accurate, and the adjustment method is simpler and more convenient. Furthermore, this implementation method can also save users who need to shoot videos with different frame rates to edit and stitch videos later, making video creation more convenient and improving user experience.

Wherein, after determining the first video frame rate corresponding to the first motion speed, the electronic device may determine whether the current video frame rate is the first video frame rate. If the current video frame rate is the first video frame rate, it is not necessary to adjust the video frame rate; if the current video frame rate is not the first video frame rate, you can adjust the video frame rate to the first video frame rate Video frame rate to record video with a more appropriate video frame rate.

In order to better understand the foregoing embodiments, an example is used below to illustrate.

For example, the target camera is set separately from the electronic device, the target camera is fixed on the pet, and the video is taken from the perspective of the pet's movement. Assume that when the recording starts, the pet moves forward at a lower speed A at a constant speed, the relative movement speed between the target camera and the scene to be photographed is small, and the video frame rate corresponding to speed A is 24fps, then adjust the video frame rate to 24fps to record video. This allows for a more cinematic and speedy low frame rate clip. When the pet runs at a higher speed B, the relative speed between the target camera and the scene to be photographed becomes larger, and the video frame rate corresponding to the speed B is 60fps, then the video frame rate is switched to 60fps for video recording. At this time, high frame rate recording can alleviate the problem of motion jitter and motion blur in high-speed motion. When the pet runs at full speed at a higher speed C, the relative speed between the target camera and the scene to be photographed is greater, and the video frame rate corresponding to the speed C is 240fps, then the video frame rate is switched to 240fps for video recording. While alleviating the motion jitter and motion blur problems in high-speed motion, it can also achieve slow-motion playback effect, that is, although the video frame rate is 240fps, because the playback frame rate is 30fps, it takes 8 seconds to record a 1-second video , so as to achieve slow motion playback. Furthermore, high-speed slow-motion recording is used for higher-speed motion, and more details can be recorded.

In the embodiment of the present application, the video frame rate corresponding to different motion speeds of the target camera can be preset, so that during the video recording process, the video frame rate corresponding to the current motion speed of the target camera can be determined according to the preset information, Thus, the video frame rate of the target camera is adjusted to the video frame rate matching the current motion speed of the target camera.

Optionally, multiple speed levels can be preset, and then the video frame rates corresponding to different speed levels can be set. Among them, each speed grade can correspond to a speed range, and there is no overlap between the speed ranges corresponding to different speed grades; it can be understood that each speed grade can also correspond to a specific speed value, and the specific speed corresponding to different speed grades The values are different. In the case that the moving speed of the target camera is relative to the moving speed of the electronic device, the speed level may also be called a relative speed level (Relative Velocity Level, RVL).

Optionally, step A1: determining the first video frame rate corresponding to the first motion speed may include:

Step A11: among the plurality of preset speed levels, determine the first speed level to which the first movement speed belongs.

In the case that each speed level corresponds to a speed range, specifically, the speed level to which the first movement speed belongs can be determined according to the speed range corresponding to each speed level, that is, the first movement speed corresponds to each preset speed level Compare the speed ranges to determine the speed range to which the first motion speed belongs, and then determine the speed class corresponding to the speed range to which the first motion speed belongs as the speed class to which the first motion speed belongs (ie, the first speed class).

In the case that each speed level corresponds to a specific speed value, specifically, the speed level to which the first movement speed belongs can be determined according to the specific speed value corresponding to each speed level, that is, the first movement speed and each preset speed The specific speed value corresponding to the level is compared. When the difference between the first movement speed and the specific speed value corresponding to a certain speed level is within the preset range, the speed level is determined as the first movement speed. The speed grade (that is, the first speed grade).

Step A12: Determine the video frame rate corresponding to the first speed level according to the preset corresponding relationship between different preset speed levels and different video frame rates.

Step A13: Determine the video frame rate corresponding to the first speed level as the first video frame rate.

In the embodiment of the present application, the corresponding relationship between different speed levels and different video frame rates is preset. Therefore, after determining the first speed level to which the first motion speed belongs, it can be based on the relationship between the speed level and the video frame rate. The preset corresponding relationship determines the video frame rate corresponding to the first speed level, and the video frame rate corresponding to the first speed level is the video frame rate corresponding to the first motion speed (first video frame rate).

The following continues to further describe how to establish the preset corresponding relationship between different preset speed levels and different video frame rates.

Optionally, before step A12: determining the video frame rate corresponding to the first speed level according to the preset correspondence between different preset speed levels and different video frame rates, the video frame rate adjustment method may further include:

There are three speed grade options, namely VL1, VL2, VL3, VL4, and VL5, as shown in the right diagram in Figure 2.

Step B2: When the second input is received, in response to the second input, determine the first speed level corresponding to the first speed level option selected by the second input, and display multiple video frame rate options.

The second input described here is used to select a speed grade among multiple speed grade options, and display multiple video frame rate options after the speed grade is selected. The second input may include, but is not limited to, at least one of the following: touch operation, voice operation, air gesture operation, and the like.

Wherein, the first speed grade option is one of multiple speed grade options.

For an optional embodiment described in step B1, correspondingly, step B2 may include: in the case of receiving the first moving operation on the floating control, in response to the first moving operation, during the moving process of the floating control , determine the first speed level corresponding to the first speed level option at the position where the floating control stays longer than or equal to the first preset duration, and display multiple video frame rate options.

Wherein, multiple video frame rate options surround the first speed level option.

In the embodiment of the present application, the floating control can move the position, and the speed level can be selected through the floating control, and the speed level options are displayed around the floating control, which can facilitate the moving of the floating control to any speed level option, User-friendly operation.

As shown in the left figure in Figure 3, the user can drag the floating ball control 201 to move to the speed level VL2 option (that is, the next speed level option of VL1 in the clockwise direction) that he wants to choose. 201 After moving to the setting area of speed level VL2 (that is, where the speed level VL2 option is located) and staying for a while, the electronic device determines that the speed level selected by the user is VL2, and then displays multiple video frames around the speed level VL2 option Rate options, namely 24fps, 30fps, 60fps, 120fps and 240fps, as shown in the right diagram in Figure 3. It can be understood that multiple video frame rate options can also be set around multiple speed level options, as shown in FIG. 4 .

Step B3: When the third input is received, in response to the third input, establish a corresponding relationship between the first video frame rate corresponding to the first video frame rate option selected by the third input and the first speed level.

Wherein, the first video frame rate option is one of multiple video frame rate options.

The third input described here is used to select the desired video frame rate (i.e. the first video frame rate) in a plurality of video frame rate options, and after selecting the required video frame rate, establish the selected video frame rate and Correspondence between the first speed grades selected in step B2. The third input may include, but is not limited to, at least one of the following: touch operation, voice operation, air gesture operation, and the like.

For an optional embodiment described in step B1 and step B2, correspondingly, step B3 may include: in the case of receiving the second movement operation on the floating control, responding to the second movement operation, During the moving process, establish a corresponding relationship between the first video frame rate corresponding to the first video frame rate option at the position where the hovering control stays longer than the second preset time length, and the first speed level.

In the embodiment of the present application, in addition to selecting the speed level, the floating control can also select the video frame rate, that is, multiple processing operations can be completed through one control, and the utilization rate is high. In addition, the recording frame rate options are displayed around the floating control, which makes it easy to move the floating control to any recording frame rate option, which is convenient for users to operate.

The optional embodiment is illustrated below by taking FIG. 5 as an example.

As shown in Figure 5, the user can drag the floating ball control 201 to move to the 30fps video frame rate option (that is, the next video frame rate option of 24fps in the clockwise direction) that he wants to select, when the floating ball control 201 moves Go to the setting area with a recording frame rate of 30fps (that is, where the 30fps recording frame rate option is located) and stop for a while, then the electronic device determines that the recording frame rate selected by the user is 30fps, and then establishes a value between the recording frame rate of 30fps and the speed level VL2. corresponding relationship.

By repeatedly executing the above steps B1 to B3, the preset corresponding relationship between different preset speed levels and different video frame rates can be established.

It should be noted that, besides being manually set by the user, the preset corresponding relationship between different preset speed levels and different video frame rates may also be set by default by the system.

As an optional embodiment, when the target parameter includes the distance change state between the electronic device and the target camera, before step 102: adjusting the video frame rate according to the target parameter, the video frame rate adjustment method may also include :

In case the fourth input is received, in response to the fourth input, a video frame rate adjustment control is displayed.

Wherein, the fourth input described here is used to display the video frame rate adjustment control, and the fourth input may include but not limited to at least one of the following: touch operation, voice operation, and air gesture operation.

Wherein, the video frame rate adjustment control may include: an indicator mark and a plurality of frame rate marks for representing different video frame rates, and the multiple frame rate marks are arranged in ascending order according to the represented video frame rates, each The frame rate marked on the frame rate mark indicates the video frame rate.

Optionally, the indicator may specifically be a pointer, and the frame rate indicator may specifically be a graphic.

As shown in the left figure of FIG. 6 , the user can call out the video frame rate adjustment control 202 by sliding two fingers on the video preview interface 200 . As shown in the right figure in Fig. 6, the video frame rate adjustment control 202 may include: a pointer 2021 (corresponding to the pointer mark) and a semi-circular figure, and the semi-circular figure includes 5 fan-shaped figures 2022 (corresponding to the frame rate mark), each fan-shaped figure 2022 represents a recording frame rate, and the five fan-shaped figures are arranged in clockwise order from small to large according to the indicated recording frame rate. Which fan-shaped graphic 2022 the pointer 2021 points to, the recording is performed based on the recording frame rate corresponding to the fan-shaped graphic 2022 pointed to by the pointer 2021 .

Optionally, the video frame rate adjustment control may be displayed before the video recording starts, or the video frame rate adjustment control may be displayed after the video recording starts.

Optionally, after displaying the video frame rate adjustment control, the video frame rate adjustment method may further include:

Receive a fifth input to the indicator; in response to the fifth input, set the video frame rate corresponding to the frame rate indicator to which the indicator is redirected as the initial video frame rate.

Wherein, the fifth input described here is used to set the initial video frame rate, and the fifth input may be a mobile touch operation or the like. The frame rate indicator to which the indicator indicator is redirected is adjusted through the fifth input.

After displaying the video frame rate adjustment control 202, the user can manually set the initial video frame rate. For example, as shown in FIG. Rate. Under the control of the finger, when the active end of the pointer 2021 points to the 30fps video frame rate option, the initial video frame rate is set to 30fps. It can be understood that the initial recording frame rate may also be set by default in the system, for example, the default setting is the minimum recording frame rate.

After completing the setting of the initial video frame rate, when the video frame rate is performed for the first time based on the change state of the distance between the electronic device and the target camera, it is adjusted on the basis of the initial video frame rate.

Optionally, step 102: adjusting the video frame rate according to the target parameters may include:

According to the change state of the distance between the electronic device and the target camera, the control indicator moves to the target frame rate indicator in the direction of decreasing video frame rate or the control indicator moves to the target frame rate indicator in the direction of increasing video frame rate , and use the target frame rate to identify the corresponding video frame rate for video recording.

Wherein, when the distance between the electronic device and the target camera becomes smaller, the indicator can be controlled to move to the target frame rate mark in the direction where the video frame rate decreases; the distance between the electronic device and the target camera becomes larger In the case of , you can control the indicator to move to the target frame rate indicator in the direction of increasing the video frame rate.

Or, when the distance between the electronic device and the target camera becomes smaller, the indicator can be controlled to move to the target frame rate mark in the direction of increasing the video frame rate; the distance between the electronic device and the target camera becomes larger In the case of , the indicator can be controlled to move to the frame rate indicator corresponding to the target video frame rate in the direction of decreasing the video frame rate.

Wherein, the target frame rate identifier is one of the plurality of frame rate identifiers used to represent different recording frame rates.

In the embodiment of this application, the video frame rate can also be adjusted according to the distance between the electronic device and the target camera. For example, when the photographer wants to reduce the video frame rate, he can control the electronic device to move closer to the target camera. When the electronic device detects that the distance between the target camera and the target camera becomes smaller, it can control the indicator to move to the target frame rate indicator in the direction of decreasing the video frame rate. For another example, when the photographer wants to increase the video frame rate, he can control the electronic device to move away from the target camera. When the electronic device detects that the distance between the target camera and the target camera becomes larger, it can control the indicator to move towards the video recorder. The direction of frame rate increase moves to the target frame rate mark. In this way, during the video recording process, the video frame rate can be dynamically adjusted to obtain videos with different video frame rates. Compared with the post-video editing method in the prior art, the method provided by the embodiment of the present application is simpler , convenient. In addition, this method of adjusting the video frame rate is also beneficial to solve the problem that it is inconvenient for users to manually trigger virtual buttons and/or physical buttons to adjust the video frame rate during the video recording process.

Wherein, in the embodiment of the present application, every time the distance state changes, the indicator moves once and points to the adjacent frame rate indicator of the current frame rate indicator, such as the previous frame rate indicator or the next frame of the current frame rate indicator Rate logo. When the user needs to adjust the video frame rate to the video frame rate corresponding to the target frame rate logo separated by a frame rate logo from the current frame rate logo, the distance change state is changed twice. If the distance becomes smaller twice, Or it happens that the distance becomes larger twice.

For example, as shown in the right figure in Figure 6, the pointer 2021 is currently pointing to the fan-shaped graphic 2022 corresponding to 60fps. If the user wants to adjust the video frame rate to 240fps, he can first control the electronic device to move once in a direction away from the target camera, so that The distance between the electronic device and the target camera increases once, and at this time the pointer points to the fan-shaped figure 2022 corresponding to 120fps. After that, the user controls the electronic device to move once in a direction away from the target camera, so that the distance between the electronic device and the target camera It becomes larger again, and at this time, the indicator points to the fan-shaped frame rate indicator 2022 corresponding to 240fps.

Optionally, the distance change state described in the embodiment of the present application may specifically include: the distance becomes smaller and the reduced distance value is greater than a preset value, and the distance becomes larger and the increased distance value is greater than the preset value. The purpose of this preset value is to avoid misuse as much as possible, and the specific value can be set according to actual needs.

Optionally, when the video frame rate adjustment control is displayed before the video recording starts, the user can set the initial video frame rate through the video frame rate adjustment control before the video recording starts. After the video recording starts, that is, after the user clicks the recording button to start recording, the recording frame rate adjustment control can no longer be controlled by the user, but automatically moves based on the distance change state between the target camera and the electronic device.

Optionally, when the target parameter includes a change in distance between the electronic device and the target camera, the target parameter may further include: a relative movement speed between the electronic device and the target camera.

The preceding steps: according to the change state of the distance between the electronic device and the target camera, control the indicator to move to the target frame rate in the direction of decreasing the video frame rate, or control the indicator to move to the target in the direction of increasing the video frame rate The frame rate identifier can include:

According to the change state of the distance between the electronic device and the target camera, the control indicator moves to the target frame rate mark in the direction of decreasing the video frame rate or increases to the video frame rate according to the second motion speed corresponding to the relative motion speed. Move to the target frame rate mark in the large direction.

In the embodiment of the present application, when the distance state between the electronic device and the target camera changes, the moving speed of the indicator may be controlled according to the relative movement speed between the electronic device and the target camera. Among them, the relative motion speed between the electronic device and the target camera can be positively correlated with the moving speed of the indicator, so that when the video frame rate needs to be quickly adjusted, the electronic device can be controlled to quickly approach or move away from the target camera , so that the relative movement speed between the two is relatively large, and the indicator moves to the target frame rate indicator more quickly.

Optionally, a formula may be preset for converting the relative movement speed between the electronic device and the target camera into the movement speed of the indicator.

As an optional embodiment, in the embodiment of the present application, a multi-frame rate fusion recording mode can be added to the electronic device. After starting the recording mode, the recording frame rate can be adjusted according to the recording frame rate adjustment method provided in the embodiment of the present application. rate adjustment.

The above is the description of the video frame rate adjustment method provided by the embodiment of the present application.

To sum up, in the embodiment of this application, the electronic device can adjust the video frame rate of the target camera according to the target parameters, such as adjusting the video frame rate of the target camera according to the moving speed of the target camera, or according to the distance between the target camera and the electronic device. Adjust the video frame rate of the target camera, so that during the video recording process, the video frame rate can be dynamically adjusted to obtain videos with different video frame rates. Compared with the post-editing in the prior art The method provided by the embodiment of the present application is simpler and more convenient.

The video frame rate adjustment method provided in the embodiment of the present application may be executed by a video frame rate adjustment device. In the embodiment of the present application, the method for adjusting the frame rate of video recording performed by the device for adjusting the frame rate of video recording is taken as an example to describe the device for adjusting the frame rate of video recording provided in the embodiment of the present application.
