At present, the camera function based on camera unit has become one of the basic functions of intelligent terminal device. Many Internet applications (APP) may call the camera unit through the terminal device to implement a series of functions such as video recording, video editing, uploading, and sharing.
In related technologies, when calling the camera unit for video shooting, APP may provide at least two function pages, that is, a video shooting page and a video editing page. Usually, the video shooting page is the default page of the camera function. A real-time shooting content is displayed through the video shooting page. After the shooting is completed, the video is edited or viewed through the video editing page.
However, in the actual use process, when returning to the video shooting page from the video editing page, the video shooting page cannot display the real-time shooting content at the first time, but will appear a black screen, affecting the smoothness and visual experience of the APP operation, and reducing the user experience.

To describe the technical solutions more clearly in the embodiments of the present disclosure or related technologies, the following will briefly introduce the drawings needed in the embodiments or related technical descriptions. Apparently, the drawings in the following description are some embodiments of the present disclosure. For ordinary technicians in the art, they can also obtain other drawings from these drawings without paying creative efforts.
To make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Apparently, the described embodiments are a part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the disclosure, all other embodiments obtained by ordinary technicians in the art without doing creative efforts fall within the scope of the protection of the present disclosure.
An application scenario of the embodiments of the present disclosure is explained below.
The method of camera function page switching provided by the embodiments of the present disclosure, for example, may be applied to application scenarios such as video shooting, editing, uploading and sharing of video APP and social APP. Specifically, the method provided in the embodiments of the present disclosure may be applied to a terminal device, such as a smart phone. The terminal device has a camera unit, such as a camera module for image collecting. For example, a video APP is running in the terminal device. This video APP implements video shooting, editing and other functions by displaying different camera function page on the terminal device and combining interactive operation instructions input by users.
After making creative efforts, the inventor found that this is because: after inputting the video editing page from the video shooting page of the APP, the camera unit may enter a non-working state, and then when returning to the video shooting page from the video editing page, the camera unit needs to restart and initialize. During this process, the camera unit cannot collect images, so there is no real-time image to be displayed in the video shooting page, forming a black screen. Therefore, how to obtain realistic images in the initialization phase of the camera unit and display them in the video shooting page to simulate the real time images shot by the camera unit, thereby causing the video shooting page to be instantly started in appearance, is an urgent problem to be solved. The embodiments of the present disclosure provide a method of camera function page switching to solve the above problem.
Referring to
At step S101: start, based on a selected first video, a video editing page for editing the first video based on an editing instruction input by a user.
For example, referring to the schematic diagram of the application scenario shown in
Further, after obtaining the first video, the video editing page may be started based on the operation instruction input by the user, such as the instruction generated for a gesture operation of a control “enter a video editing page”. Alternatively, after obtaining the first video, the editing page may be automatically started according to the predetermined program logic without user operation, which may be set according to specific needs, and no more examples will be given one by one.
Herein, the video editing page may be a program function module including a display interface provided in the APP, and the video editing page is used to edit the first video based on an editing instruction input by the user. Specifically, through the video editing page, for example, video playback, video information display (such as video duration, video size, resolution, etc.) and other display functions may be implemented for the previously shot video (the first video). For another example, the video information modification (such as video name modification, classification tag modification, etc.), video compression, video uploading, video publishing and other functions may be implemented for the previously shot video (the first video), thereby implementing various editing operations for the first video after recording. It may be set according to specific needs. The functions of editing the first video that may be implemented in the video editing page are not specifically limited here. Meanwhile, based on the specific functions of the video editing page, the layout and style of various controls and icons in the display interface of the video editing page may also be set as needed, which will not be detailed here.
After the video editing page is started, the user may view the video and related information through the interactive interface of the terminal device, and then perform corresponding editing operations on the video. The specific editing operations have been illustrated in the previous steps and will not be repeated here. Of course, users may also view without editing in the video editing page, which will not be repeated here.
At step S102: in response to a shooting trigger instruction for the video editing page, close the video editing page and start a video shooting page.
For example, after completing the above steps, the user inputs a return operation to the terminal device, and the terminal device generates and responds to a corresponding shooting trigger instruction, which is used to close the video editing page and return to the video shooting page. Herein, for example, the video shooting page, similar to the video editing page, may be a program function module including a display interface provided in the APP, which displays the real-time images collected by the camera unit by calling the interface of the camera unit provided by the operating system. Starting the video shooting page is the process of starting the program function module. Herein, the video shooting page includes at least one control for saving the real-time image collected by the camera unit as video data, i.e., a shooting control. After the shooting control is triggered, the terminal device will start video shooting.
In one possible implementation, after closing the video editing page and before starting the video shooting page, the following steps are also included.
A rendering environment is set as an initialized rendering environment, where the initialized rendering environment is used to draw the video shooting page and the preview image in the display interface.
Specifically, the terminal device has a display interface, and the video shooting page and video editing page are displayed through the display interface. While the video shooting page and video editing page are displayed through the display interface, the rendering environment needs to be supported. Specifically, the rendering environment includes rendering methods, types, parameters, and other information. Since the video shooting page and video editing page are implemented through different program function modules, they correspond to different rendering environment. After the video editing page, to implement the subsequent display of the video shooting page, the rendering environment needs to be initialized, and the rendering environment needs to be set to the initialized rendering environment, so that the video shooting page may be displayed normally.
At step S103: obtain a preview image based on the first video, and display the preview image in the video shooting page, wherein the preview image comprises at least one video frame generated based on the first video.
For example, the preview image is image data generated from the first video. Specifically, the preview image includes at least one video frame generated based on the first video. In one possible implementation, the preview image includes one video frame in the first video, that is, a picture, such as the last frame image of the first video. After starting the video shooting page, it takes a certain time for the camera unit to start and initialize, such as 400 ms. During this period, the real collected real-time image cannot be obtained through the camera unit, so the real-time image cannot be displayed instantaneously in the video shooting page, resulting in a black screen. In the embodiments of the present disclosure, by intercepting at least one frame of data from the first video and displaying it in the video shooting page, the video shooting page is instantly started in appearance to avoid the black screen problem.
In another possible implementation, the preview image includes a plurality of continuous frames of pictures, that is, the preview image may be regarded as a video clip, such as the last 0.1 second video clip in the first video. More specifically, displaying the preview image in the video shooting page includes displaying the plurality of continuous frames of pictures sequentially in the video shooting page within a predetermined duration. The predetermined duration characterizes an initialization duration of the camera unit. In the step of the embodiments of the present disclosure, by displaying the plurality of consecutive frames (video clip) in the first video as the preview image in the video shooting page, the display smoothness and authenticity of the video shooting page may be further improved and the visual effect may be improved while avoiding the black screen problem.
Meanwhile, referring to the schematic diagram of the application scenario shown in
Furthermore, after step S103, the method further includes the following steps.
At step S104: collect a second video through the camera unit after initialization of the camera unit is completed.
At step S105: jump to the video editing page and play a synthesized video through the video editing page, wherein the synthesized video is generated after processing the first video and the second video based on a target editing operation.
For example, after the camera unit is initialized, the terminal device collects real-time images through the camera unit, and the real-time images are displayed in the video shooting page. Since the preview image used in the above steps is generated through the video frame in the first video, the similarity between the preview image and the real-time image actually collected by the camera unit is higher. Therefore, after the camera unit initializes and displays the real-time image in the video shooting page, the frame skipping phenomenon between the two images (that is, the preview image and the real-time image) is smaller, even making it difficult for the user to find the frame skipping phenomenon and improving the smoothness of starting the video shooting page.
Further, after the camera unit is initialized, the method further includes the following.
The second video is obtained by collecting real-time images through the camera unit. The video editing page is started and jumped to, and the synthesized video is played through the video editing page. The synthesized video is generated after processing the first video and the second video based on a target editing operation.
For example, after the real-time image is collected through the camera unit, the second video is obtained, and the user may further edit the second video. In this case, the terminal device responds to a jumping instruction input by the user, starts and jumps to the video editing page to edit the second video. Specifically, in one possible implementation, the terminal device synthesizes the first video and the second video to generate a better-quality synthesized video. More specifically, compared with the second video, the synthesized video may have at least one of the following advantages: higher frame rate, higher resolution, and fewer noise points. So that the APP may generate better-quality videos in the function mode of the process of “shooting-editing-shooting-editing”.
Herein, for example, the video shooting page is displayed through the display interface of the terminal device.
In the embodiments of the present disclosure, after shooting the first video through the camera unit of the terminal device, the video editing page is started, and the video editing page is used to edit the first video based on the editing instruction input by the user. In response to the shooting trigger instruction for the video editing page, the video editing page is closed and the video shooting page is started. The preview image is obtained based on the first video, and the preview image is displayed in the video shooting page until the camera unit is initialized. The preview image includes at least one video frame generated from the first video. When returning to the shooting page from the editing page, the preview image obtained from the first video shot previously will be displayed in the shooting page after processing, so as to avoid the video shooting page being in a black screen state, so that the video shooting page may instantly display the shot content in the appearance, thus improving the smoothness and appearance of generating synthesized video and improving the user experience.
Referring to
At step S201: after shooting a first video through a camera unit of a terminal device, start a video editing page for editing the first video based on an editing instruction input by a user.
At step S202: in response to a return instruction for the video editing page, close the video editing page.
At step S203: obtain first pose information and second pose information, wherein the first pose information characterizes a body angle of the terminal device when shooting the first video, and the second pose information characterizes a current body angle of the terminal device.
For example, pose information is information used to characterize a shooting angle of the terminal device when shooting videos, that is, a body angle of the terminal device, where the body angle includes both a horizontal rotation angle and a vertical rotation angle of the body. Specifically, it may be obtained by collecting angle information through a sensor set in the terminal device, such as a gyroscope sensor. The first pose information is a body angle of the terminal device when shooting the first video, and the second pose information characterizes a current body angle of the terminal device, that is, the body angle when starting the video shooting page.
Herein, in one possible implementation, the first pose information is synchronously collected when the first video is shot. The first pose information includes pose sequence. The pose sequence includes at least one pose value. A pose value characterizes a body angle of the terminal device in the process of shooting the first video, and each pose value corresponds to a video frame. The second pose information is a value characterizing a body angle obtained in real time when starting the video shooting page. The pose value in the first pose information has the same data structure as the pose value in the second pose information. Therefore, the pose value of the first pose information may be compared with the pose value in the second pose information to achieve the comparison of body angle.
At Step S204: obtain a target frame in the first video based on the first pose information and the second pose information, wherein an angle difference between a body angle corresponding to the target frame and a body angle corresponding to the preview image is less than an angle threshold value.
In the application scenario corresponding to the embodiments of the present disclosure, when a user uses a terminal device (such as a smart phone) to shoot a short video, and when the user's own position and environment do not change significantly, the content of the image shot by the terminal device through the camera unit has a fixed mapping relationship with the shooting angle, that is, when the shooting angle is the same, the content of the image shot by the terminal device is similar or even the same. Based on the above discovery of the inventor, by using the different pose value in the first pose information to compare with the second pose information, the video frame shot from a body angle that is the same as the current body angle is taken as the target frame, and in the subsequent steps, the preview image is generated based on the target frame and displayed on the video shooting page, realizing the accurate prediction of the real-time image not displayed in the video shooting page (because the camera unit has not completed the initialization), making the image content in the preview image more similar to the image content of the real real-time image collected by the camera unit, and realizing a realistic replacement of the “black screen” process and improving the user's perception.
In one possible implementation, the target frame includes a plurality of continuous frames of pictures. The first pose information includes a pose sequence and a corresponding timestamp sequence. The pose sequence includes at least one pose value. The pose value characterizes a body angle of the terminal device during the shooting of the first video. The timestamp sequence includes at least one timestamp. The timestamp corresponds to a pose value. The timestamp characterizes the obtaining time of the pose value, as well as the playing time of the first video. As shown in
At step S2041: determine a first body angle based on the second pose information.
At step S2042: determine a target pose value and a corresponding target timestamp based on the first body angle and the first pose information.
At step S2043: determine the plurality of continuous frames of pictures based on the target timestamp corresponding to the target pose value and at least one timestamp subsequent to the target timestamp.
For example, the second pose information is the value characterizing a body angle obtained in real time when starting the video shooting page. Based on the value characterizing the body angle corresponding to the second pose information, the pose sequence corresponding to the first pose information is traversed to obtain the closest pose value, that is, the target pose value. Further, based on the timestamp sequence corresponding to the pose sequence, the target timestamp corresponding to the target pose value is obtained. After obtaining the target timestamp, the video frame corresponding to the target timestamp is obtained based on the corresponding relationship between the timestamp sequence and the first video, and then, for example, the corresponding video frames are obtained based on several consecutive timestamp subsequent to the target timestamp, so as to obtain the plurality of continuous frames of pictures, that is, target frame.
In the embodiments of the present disclosure, through the first pose information and the second pose information, the plurality of consecutive video frame matching the current body angle are obtained, and then the video clip may be displayed in the video shooting page as the preview image in the subsequent steps. While avoiding the “black screen” problem, the real-time image actually collected by the video shooting page is further simulated, so that the user may not perceive the start delay of the high video shooting page caused by the initialization process of the camera unit, improving the smoothness of operation and the user's experience.
At step S205: generate the preview image based on the target frame, wherein the preview image comprises a plurality of continuous frames of pictures.
For example, in one possible implementation, the target frame is the preview image, and the two are the same. The target frame generated in the above step, that is, the plurality of continuous frames of pictures, is directly used as the preview image for subsequent processing. In another possible implementation, the target frame obtained in the above steps may be processed, such as image frame fusion, image interpolation and other video processing steps, to generate the preview image, so that the image quality of the preview image is better and smoother. Herein, the specific implementation of the above video processing process is based on existing technology, which will not be repeated here.
At step S206: perform Gaussian blurring on the preview image to obtain an image to be displayed.
Optionally, after step S205, the image may be further performed Gaussian blurring on to generate an image to be displayed. Thus, the user may not observe the details of the image displayed in the video shooting page temporarily and may not perceive the process of terminal device replacing the “black screen” with the image to be displayed, so as to improve the user's experience. Herein, the steps for image processing mentioned above may be set according to specific needs, and the specific implementation is based on existing technology, which will not be repeated here.
At step S207: initialize the camera unit through a first process to start the video shooting page.
At step S208: display the preview image in the video shooting page through a second process until the initialization of the camera unit is completed.
For example, after obtaining the preview image, on the one hand, the “black screen” in the video shooting page may be avoided by displaying the image to be displayed; on the other hand, the video shooting page may be started by initializing the camera unit. At this time, the start of the video shooting page refers to the full start of the video shooting page, that is, the real time image actually shot by the camera unit may be obtained by calling the camera unit. In the steps of the embodiments of the present disclosure, by processing the initialization process of the camera unit and the display process of the image to be displayed (preview image) in separate process, the image to be displayed (preview image) may be displayed in the video shooting page for the first time, which may not be affected by the camera initialization process, implementing the appearance of instant startup of the video shooting page, and improving the visual effect and smoothness of operation.
At step S209: collect a second video through the camera unit after initialization of the camera unit is completed.
At step S210: jump to the video editing page and play a synthesized video through the video editing page, wherein the synthesized video is generated after processing the first video and the second video based on a target editing operation.
In the embodiments of the present disclosure, the implementation ways of step S201, step S202, step S209, and step S210 are the same as those of step S101, step S102, step S104, and step S105 in the embodiments shown in
