Referring now to FIG. 2A and FIG. 2B , the illustrations are schematic diagrams of the user interface of the time-lapse photography image area division according to the embodiment of the present application. In this embodiment, the terminal device is described by taking a mobile phone as an example.

As shown in FIG. 2A , before video recording, the user can click the shape control 12 in the lower left corner of the recording screen, and then a variety of shape options will appear, and custom shape drawing can also be provided. The user can drag one of the shapes to the shooting preview interface corresponding to the recording screen, and can adjust the size and position of the shape. This shape divides the shooting preview interface into two parts.

For example, in the embodiment in FIG. 2B, the user selects a circle, and the circle is displayed in the shooting preview interface. The user can manually adjust the size and position of the circle. At this time, the image area 1 corresponding to the circle is set to extend time-lapse image area.

If the user only chooses to set the image area 1 as the time-lapse photography image area, it is determined that the image areas except the image area 1 of the recording screen are all non-time-lapse photography image areas.

In the embodiment of the present application, the video frames in the time-lapse photography image area will present the shooting effect of time-lapse photography, and the video frames in the non-time-lapse photography image area will present a still video frame, that is, in the entire During the playback of the captured video, the video frame in the non-time-lapse photography image area can correspond to display a frame of still image that does not change.

Of course, in other embodiments, the video frames in the non-time-lapse photography image area may correspond to video frames displaying other shooting effects.

As mentioned above, the corresponding shape is selected from the shape control according to the user's operation, so as to determine the time-lapse photography image area. In one embodiment, if the user wishes to separate multiple areas, multiple shapes can be pulled to the preview interface at the same time, so as to set multiple time-lapse photography image areas at corresponding positions on the shooting preview interface. As shown in Figure 3A, the user first pulls a circle to the shooting preview interface, and then as shown in Figure 3B, the user pulls a rectangle to the shooting preview interface. At this time, the image area 1 corresponding to the circle and the image corresponding to the rectangle Area 2 is set as a time-lapse photography image area, and image area 3 other than image areas 1 and 2 is set as a non-time-lapse photography image area.

If the user wants to set the position of the image area corresponding to the pulled shape as a non-time-lapse photography image area, and set the image area of the rest of the recording screen as a time-lapse photography image area, it can be set according to the corresponding input operation of the user.

Optionally, the image area surrounded by the target shape is determined as the time-lapse photography image area, and other image areas other than the target shape are determined as the non-time-lapse photography image area, after that, It also includes: receiving a second input from the user; in response to the second input, determining the image area surrounded by the target shape as the non-time-lapse photography image area, and determining other image areas other than the target shape Determine the image region for the time-lapse photography.

Through the above embodiments, switching between the time-lapse photography image area and the non-time-lapse photography image area can be realized.

The second input can be: the user's click input on the target control displayed on the shooting preview interface, or a voice command input by the user, or a specific gesture input by the user, which can be determined according to actual use requirements. Not limited.

Referring to FIG. 4A , the second input is, for example, the user clicks the inversion icon 14 in the lower right corner of the shooting preview interface to set, so that the image area 1 and image area 2 that have been set as time-lapse photography image areas in FIG. 4A can be modified and set to non- The time-lapse photography image area, and at the same time, the image area 3 that has been set as the non-time-lapse photography image area in 4A is modified and set as the time-lapse photography image area. That is, switching between the time-lapse photography image area and the non-time-lapse photography image area in FIG. 4A is realized.

In addition, if the user wants to cancel a certain time-lapse photography image area that has been set, he can click the shape of the time-lapse photography image area that has been set on the shooting preview interface, and then click Cancel to modify the time-lapse photography image area to a non- Time-lapse photography image area. At this time, the default time-lapse photography image area is the image area corresponding to the shape pulled by the user to the shooting preview interface and not canceled, and other areas of the shooting preview interface are determined to be non-time-lapse photography image areas.

In one embodiment, in order to meet the user's needs for recording various interesting videos, after determining the time-lapse photography image area and the non-time-lapse photography image area, various rendering settings can be performed on the time-lapse photography image area according to the user's selection , such as shooting color parameter settings, dynamic change process settings, etc.

Optionally, after the determining the time-lapse photography image area and the non-time-lapse photography image area, it also includes: receiving a third input from the user on the color control; in response to the third input, determining the time-lapse photography image area shooting color parameter information.

The shooting color parameter information includes the color change duration and the corresponding color pixel value. The color change duration is to set the duration of the dynamic video corresponding to the color change, and the duration can run through the entire dynamic video. A playback time period, or part of a dynamic video playback time period. The color pixel values include brightness values and/or RGB pixel values corresponding to dynamic video playback.

Referring now to FIG. 5A and FIG. 5B , the figure is a schematic diagram of a user interface for setting shooting color parameter information of a time-lapse photography image area according to an embodiment of the present application.

Before recording the video, the user can click the "color" control in the lower right corner of the shooting preview interface shown in Figure 5A to set the color change of the entire time-lapse photography image area, as shown in Figure 5B, which shows the color change setting control 16, where the curve From left to right, it represents the color change from the beginning to the end of the last generated time-lapse photography image area. For example, if you pull it up, the color pixel value will become larger; if you pull it down, the color pixel value will become smaller.

Optionally, after determining the time-lapse photography image area and the non-time-lapse photography image area, it also includes: receiving a fourth input from the user on the dynamic control; in response to the fourth input, determining the area of the time-lapse photography image area Change information, the area change information is used to indicate the dynamic change process of the time-lapse photography image area.

The area change information includes the dynamic change type, dynamic change duration and dynamic change speed of the time-lapse photography image area. The dynamic change type indicates the shape change mode of the time-lapse photography image area corresponding to the dynamic video, for example, corresponding to circular time-lapse photography The image area can gradually become larger, gradually smaller, gradually larger and then gradually smaller as the video plays, repeated changes, or single changes, etc. The dynamic change duration indicates the change time of the shape of the time-lapse photography image area corresponding to the dynamic video, including changing throughout the entire playing time period of the video, or changing within a part of the playing time period. The speed of dynamic change, for example, the time required for the shape of the time-lapse photography image area where the dynamic video corresponds to change from one shape size to another shape size, the change speed is fast and the time is short, and vice versa.

Next, refer to FIG. 6 , which is a schematic diagram of a user interface for dynamically changing settings of a time-lapse photography image area according to an embodiment of the present application.

Before recording the video, the user can click, for example, the diffusion icon 18 in the lower right corner of the shooting preview interface shown in Figure 6 to set the dynamic change. The user clicks the diffusion icon 18, and various dynamic change types of the time-lapse shooting area will pop up: dynamic diffusion-single times, dynamic spread-repeat, dynamic spread-shrink, static surround-single, static surround-repeat, static surround-diffuse.

When the user slides his finger to the corresponding type, the time-lapse shooting area may change in the shooting preview interface at this time, prompting the user the effect of the setting of this type.

As shown in Figure 7A, when the user presses "Dynamic Diffusion-Single", a dynamic effect will appear on the shooting preview interface at this time: the circular time-lapse photography image area of the preset size originally set by the user is defined by its center (virtual center, invisible to the user), and gradually expand proportionally until the entire preview area is covered, such as Figure 7A, Figure 7B and Figure 7C. The time from the preset size of the time-lapse photography image area to the entire preview area is related to the preset shape and size of the time-lapse photography image area, the size of the preview area corresponding to the recording screen, and the dynamic change speed.

As shown in Figure 8A, if the user presses "Dynamic Diffusion-Contraction", a dynamic effect will appear on the shooting preview interface at this time: the circular time-lapse photography image area with the preset size originally set by the user gradually spreads and becomes large until it fills the entire preview area, as shown in Figure 8B. Then gradually shrink to the circular position originally set by the user, as shown in FIG. 8C .

As shown in FIG. 9 , if the user selects “Dynamic Diffusion-Contraction-Repeat”, the dynamic effects shown in FIG. 8A to FIG. 8C will appear repeatedly on the shooting preview interface until the user slides his finger away.

As shown in Figure 10A, when the user slides to the "Static Bracketing-Single" option, a dynamic effect appears on the shooting preview interface: from the entire preview interface corresponding to the time-lapse shooting area, the circular time-lapse shooting area gradually shrinks, and the circle The shape time-lapse shooting area becomes smaller and smaller until the circular time-lapse photography image area of the preset size originally set by the user is shown in FIG. 10A , FIG. 10B and FIG. 10C .

When the user selects "Static Bracket-Repeat", the preview interface will repeat the effects shown in Figure 10A, Figure 10B and Figure 10C.

When the user selects "Static Surrounding-Diffusion", the effects shown in Figure 10A, Figure 10B and Figure 10C appear first, and then the effects shown in Figure 7A, Figure 7B and Figure 7C appear.

Users can also choose "static surround-diffusion-repeat", that is, to repeat the above-mentioned "static surround-diffusion" effect.

When the user selects a certain setting type according to his own needs, such as double-clicking, as shown in Figure 11, a time bar 20 appears below the diffusion icon, and the center of the time bar 20 shows the duration required for the dynamic effect once, such as "0.5s" in the illustration , the user can slide the time bar left and right to adjust the time, so as to set the dynamic change duration corresponding to the time-lapse photography image area.

Step 106, based on the time-lapse photography image area and the non-time-lapse photography image area, record and obtain the target time-lapse photography video.

The time-lapse photography image area corresponds to the dynamic video captured in the time-lapse photography mode, and the non-time-lapse photography image area corresponds to any frame image in the dynamic video captured in the time-lapse photography mode, that is, a static image.

In one embodiment, the target time-lapse video may only include dynamic video of the time-lapse image region. Or, the target time-lapse photography video may include both the dynamic video of the time-lapse photography image area and the static image of the non-time-lapse photography area.

Optionally, based on the time-lapse photography image area and the non-time-lapse photography image area, recording Obtaining the target time-lapse photography video includes: receiving a fifth input from the user on the shooting preview interface; in response to the fifth input, recording a first time-lapse photography video; based on the time-lapse photography image area, Each video image frame in a time-lapse photography video is cropped to obtain a second time-lapse photography video; each video image frame in the second time-lapse photography video is synthesized with the first static image respectively to obtain the A target time-lapse video; wherein, the first static image is an image of a non-time-lapse image area corresponding to a first video image frame in the first time-lapse video.

In this embodiment, the target time-lapse video corresponds to a time-lapse image area and a non-time-lapse image area.

The fifth input can be: the user's click input on the recording control displayed on the shooting preview interface, or a voice command input by the user, or a specific gesture input by the user, which can be determined according to actual usage requirements. Not limited.

After determining the time-lapse photography image area and the non-time-lapse photography image area, the user, for example, clicks the recording button on the shooting preview interface of the terminal device to perform normal video recording. At this time, the entire shooting preview interface follows the time-lapse photography corresponding to the time-lapse photography image area Frame rate, the image data output by the image sensor is collected until the user closes the recording button. Thus, the recorded video corresponding to the time-lapse photography image area in the time-lapse photography mode is collected.

According to the shape of the time-lapse photography image area set by the user, each video image frame of the time-lapse photography video collected in the entire shooting preview interface is cropped to obtain a time-lapse photography video corresponding to the time-lapse photography image area after cropping.

If there are multiple time-lapse photography image areas, each frame of the video image frame in each time-lapse photography video is cut out in a one-to-one correspondence according to the shape corresponding to each time-lapse photography image area, and multiple time-lapse photography frames are obtained after cutting. The time-lapse video corresponding to the time-lapse photography image area.

According to the shape of the set non-time-lapse photography image area, the target video image frame in the time-lapse photography video is cropped to obtain a static image corresponding to the non-time-lapse photography image area. The target video image frame is, for example, the first frame image of the time-lapse photography video corresponding to the time-lapse photography image area, it may also be an intermediate frame image, or the last frame image, or any one of the frame images, and the present invention is not limited to The specific examples above.

Combining the static image with each video image frame in the second time-lapse video to obtain a target time-lapse video including a plurality of synthesized video frames.

For example, the time-lapse photography video in the time-lapse photography image area is an image of 60 frames corresponding to the shape, and the static image in the non-time-lapse photography image area is an image of one frame of corresponding shape, then this frame of static image can be combined with the 60 frames of image respectively Synthesis, so as to get 60 frames corresponding to the target delay of the complete shooting preview interface photography video.

When the synthesized target time-lapse video is played, the time-lapse videos of all time-lapse image areas can be played simultaneously, and the non-time-lapse image areas remain still images. In this way, it is possible to perform video recording of time-lapse photography in a specific area of the terminal device, and the recorded video in a specific area can be presented with a time-lapse shooting effect.

As mentioned above, in one embodiment, the shooting color parameter information of the time-lapse photography image area may be predetermined. Therefore, color adjustment can be performed on the target time-lapse photography video recorded based on the time-lapse photography image area and the non-time-lapse photography image area according to the shooting color parameter information.

Specifically, according to the duration of the target time-lapse photography video and the color change duration of the time-lapse photography image area, determine the video image frame corresponding to the color change in the target time-lapse photography video; adjust each video according to the color pixel value of the target time-lapse photography video The color of the image frame.

If the set color change duration is the same as the duration of the target time-lapse video, select the video image frame of the entire target time-lapse video, and adjust the color of each frame of the video image according to the corresponding color pixel value. If the set color change duration is shorter than the duration of the target time-lapse video, select some video image frames of the target time-lapse video according to the corresponding ratio according to the starting time point of the color change duration, and adjust each frame according to the corresponding pixel value The color of the video image.

Finally, each frame of the video image in the time-lapse photography image area after color adjustment and the static image in the non-time-lapse photography image area are synthesized into a final video. In this way, the recorded video of a specific area of the terminal device can be presented not only with a time-lapse shooting effect, but also with a dynamic color change effect, which can highlight the shooting theme and improve the user's photo experience.

As mentioned above, in one embodiment, the area change information of the time-lapse photography image area may be predetermined. Therefore, according to the area change information, the dynamic change process setting can be performed on the target time-lapse video recorded based on the time-lapse photography image area and the non-time-lapse photography image area.

Specifically, according to the duration of the target time-lapse photography video and the dynamic change type and dynamic change duration of the time-lapse photography image area, determine the video image frame corresponding to the dynamic change in the target time-lapse photography video; according to the preset time-lapse photography image area The shape and size, the size of the corresponding area of the recording screen and the dynamic change speed of the time-lapse photography image area determine the shape and size of the time-lapse photography image area in each video image frame. Finally, the final video is synthesized by combining each frame of video image in the time-lapse photography image area with the dynamic change process and the static image in the non-time-lapse photography image area. In this way, the recorded video of a specific area of the terminal device can be presented not only with a time-lapse shooting effect, but also with a dynamic shape change effect, which can highlight the shooting theme and improve the user's photo experience.

Of course, the user can set the shooting color parameter information and area of the time-lapse photography image area at the same time Change information, so that the recorded video of a specific area of the terminal device is not only presented with a time-lapse shooting effect, but also presented with a dynamic shape change effect and color change effect.

In addition, after the user completes the shooting and generates the corresponding target time-lapse video, if the static image in the non-time-lapse photography image area is not satisfied, the static image can also be readjusted.

Optionally, after the obtaining of the target time-lapse video, the method further includes: receiving the user's first response to the second video frame in the case of displaying the second video frame in the target time-lapse video. Sixth input: in response to the sixth input, update the image of the non-time-lapse photography image area corresponding to the second video image frame.

The second video image frame is any frame of video image in the target time-lapse photography video, and the sixth input can be: the user's click input on the second video image frame in the target time-lapse photography video, or a voice command input by the user, or The specific gesture input by the user may be specifically determined according to actual usage requirements, which is not limited in this embodiment of the present application.

After the target time-lapse video is obtained, a corresponding frame of image is selected from the target time-lapse video based on the sixth input, and the current static image in the non-time-lapse image area is replaced based on the selected image. As a result, the user is provided with a way to replace the static image in the non-time-lapse photography image area, which further improves the fun and practicality of recording video.

Figure 12 shows a schematic diagram of video production corresponding to the time-lapse photography video recording method in an embodiment of the present application. In this embodiment, the user presets the shooting color parameter information of the time-lapse photography image area respectively. and regional change information.

The leftmost side shown in Figure 12 is the time-lapse video image frame a collected according to the preset time-lapse photography frame rate, and then, the time-lapse photography image area corresponding to each frame image in the time-lapse photography video determined according to the area change information The shape of each captured video image frame a is cropped to obtain each time-lapse photography image frame b after the shape changes dynamically. At the same time of clipping, color adjustment is performed on each collected video image frame a according to the shooting color parameter information, for example, for N frames of video images, corresponding to the set color 1, color 2, ..., color N-1, color N Color adjustment is performed to obtain each time-lapse photography image frame c after the dynamic color change.

That is to say, by simultaneously cropping and color-adjusting the collected video image frames a, each frame of video image has its own corresponding dynamic color and dynamic shape, and then these video image frames are synthesized to obtain image frame b The corresponding shape dynamic change effect and the dynamic video d of the color dynamic change effect corresponding to the image frame c.

Finally, the preset static image frame, such as any frame of video image in the time-lapse photography video image frame a, is synthesized with each time-lapse photography video image frame in the dynamic video d respectively, to obtain the target time-lapse photography The image frame of the time-lapse shooting video, wherein the time-lapse photography image area in the target time-lapse shooting video presents the time-lapse shooting video playback effect of the dynamic change process of color and shape.
