Specifically, fig. 1 shows a flowchart of a method for generating a dynamic image according to an embodiment of the present application, where the method for generating a dynamic image can be applied to a terminal device.
The method for generating a dynamic image may include:
step S101, when a first instruction is detected, a display image is obtained from a display interface of the terminal equipment every target duration, and the obtained display image is used as a dynamic image frame.
In the embodiment of the present application, the file type of the dynamic image may be various, and is not limited herein. For example, the file type of the Moving image may be one or more of Graphics Interchange Format (GIF), Moving Pictures Experts Group (MPEG), Audio video interleaved Format (AVI), and the like.
In an embodiment of the present application, the first instruction may instruct to acquire a dynamic image frame. In some examples, the first instruction may be generated upon receiving a first operation of the terminal device by a user. For example, the first instruction may be generated after receiving a touch operation of a user on a first virtual key on a display interface of the terminal device. Of course, the first operation may also be other operations besides the touch operation, and may be determined according to an actual application scenario. For example, the first operation may be a pressing operation of a first key on the terminal device by the user, or the like.
In this embodiment, the content of the display image in the display interface of the terminal device is not limited herein. In some examples, the display image may include a preview image acquired by a camera in real time; or, the display image may include content such as a preset application, a video, and the like displayed on the display interface, where the content may change according to the interaction operation of the user, and at this time, the plurality of dynamic image frames may reflect a change situation of the content along with the interaction operation of the user.
In the embodiment of the present application, the target duration may be preset by a user, or may be determined according to an actual application scenario. For example, in some examples, when the first instruction is detected, a scene category and/or a category of the target object in a currently displayed image in a display interface of the terminal device may be identified, and the target duration may be determined according to the scene category and/or the category of the target object. For example, if the object type in the currently displayed image includes an animal with a fast running speed, such as a cat, a dog, a horse, etc., the object duration may be made smaller, so as to shorten the time interval of the acquisition time of each dynamic image frame, so as to improve the frame rate of the dynamic image, and ensure that the content of the animal in the subsequently generated dynamic image has a better display effect.
In the embodiment of the application, after each dynamic image frame is acquired, the thumbnail of each dynamic image frame can be displayed in the preset menu bar of the display interface of the terminal device according to the sequence of the acquisition time of each dynamic image frame, so that a user can refer to and compare each dynamic image frame through the preset menu bar.
And step S102, when the second instruction is detected, generating a dynamic image according to the sequence of the acquisition time of each dynamic image frame and each dynamic image frame.
In an embodiment of the present application, the second instruction may instruct to stop acquiring the moving image frame and to generate the moving image. In some examples, the second instruction may be generated after receiving a second operation of the terminal device by the user. For example, the second instruction may be generated after receiving a touch operation of the user on a second virtual key on the display interface of the terminal device. Of course, the second operation may also be other operations besides the touch operation, and may be determined according to an actual application scenario. For example, the second operation may be a pressing operation of a second key on the terminal device by the user, or the like.
In this embodiment, the frame rate of the dynamic image may be determined according to the target duration, so that the dynamic image is generated according to the frame rate and each dynamic image frame.
In some application scenarios, the storage space required by the dynamic image is often small, so that a user can use the dynamic image as a dynamic expression package in various applications or publish dynamic and reduced content on a social platform. At this time, the user often has a low demand for display accuracy of the moving image, and is more concerned about whether it is easy to store, easy to produce, and easy to spread.
Therefore, the embodiment of the application can provide the method for generating the dynamic image, which is convenient for a user to quickly and conveniently make the dynamic image, and has shorter required storage space and operation time.
In some embodiments, when the second instruction is detected, generating a dynamic image according to the order of the acquisition time of each dynamic image frame and each dynamic image frame includes:
when a second instruction is detected, determining the frame rate of the dynamic image according to the target duration;
sequencing the dynamic image frames according to the sequence of the acquisition time of the dynamic image frames;
and generating the dynamic image according to the sequence, the frame rate and each dynamic image frame.
In this embodiment, the frame rate of the dynamic image may be derived according to the target duration. For example, if the target time length is 0.02 seconds, the frame rate may be 50 frames/second. Of course, in some embodiments, the frame rate may be adjusted according to the target duration according to the user's requirement. For example, if the user desires that the playback speed of the moving image is x times the image display speed of the display interface, the frame rate of the moving image may be obtained by calculating an initial frame rate from the target duration and then multiplying the initial frame rate by x.
In this embodiment, the dynamic video frames may be acquired through the display interface, and the frame rate of the dynamic image is determined according to the target duration, so as to quickly generate the dynamic image according to the plurality of static dynamic video frames, and the format of the generated dynamic image is often the format expected by the user, and operations such as format conversion and the like are not required, and the user does not need to record the video and then correspondingly edit the video, thereby greatly improving the generation speed of the dynamic image.
In some embodiments, the step S101 specifically includes:
step S201, displaying a preview image acquired by a camera in real time on a display interface of the terminal equipment;
step S202, when a first instruction is detected, a preview image is acquired from the display interface every target duration, and the acquired preview image is used as a dynamic image frame.
In the embodiment of the application, the preview image acquired by the camera in real time can be displayed on the display interface of the terminal device, when the first instruction is detected, a preview image is acquired from the display interface every target time length, and the acquired preview image is used as the dynamic image frame. At the moment, each dynamic image frame can reflect the change condition of the content of the preview image of the camera along with time, and meanwhile, the camera does not need to execute the operation of recording the video, so that the consumption of power consumption, storage space and the like of terminal equipment caused by recording the video is avoided.
The manner of obtaining the preview image from the display interface may be various. For example, the screen capture operation may be performed on the display interface to obtain a screen capture image, and then the screen capture image is cropped to obtain a preview image in the screen capture image. In addition, the preview image can be directly cut from the display interface.
In some embodiments, the acquiring a preview image from the display interface every target duration when the first instruction is detected, and taking the acquired preview image as a dynamic image frame includes:
when a first instruction is detected, screen capture operation is carried out on the display interface every target time length to obtain a plurality of screen capture images;
respectively identifying the areas of the preset images contained in the screen capture images;
and respectively cutting each screen capture image according to the area of the preset image contained in each screen capture image to obtain preview images respectively corresponding to each screen capture image, and taking the obtained preview images as dynamic image frames.
In this embodiment of the application, the screen capture image may be a full-screen display image of the display interface. In a specific application scenario, the preview image acquired by the camera in real time may be displayed in a full screen on the display interface, or may be displayed only in a partial area of the display interface, so that an area where a preset image included in each of the screenshot images is located may be identified, and each of the screenshot images is cropped according to the area where the preset image included in each of the screenshot images is located, so as to obtain a preview image corresponding to each of the screenshot images. In some examples, the area where the preset image included in each screenshot image is located may be identified through an edge detection algorithm, a convolutional neural network model, or the like, and a specific identification method is not limited herein.
In some embodiments, the acquiring a preview image from the display interface every target duration when the first instruction is detected, and taking the acquired preview image as a dynamic image frame includes:
when a first instruction is detected, acquiring coordinate information of a display area in which the preview image is displayed in the display interface;
and intercepting the preview image positioned in the display area from the display interface according to the coordinate information every target time length, and taking the intercepted preview image as a dynamic image frame.
In the embodiment of the application, for example, the layout information of the control displaying the preset image on the display interface may be acquired, so as to acquire the coordinate information of the display area of the preview image; in addition, the edge of the preset image may be identified by an edge detection algorithm, a convolutional neural network model, or the like, so as to acquire the coordinate information of the display area of the preview image. In some examples, the display area may be a rectangular area, and thus, the coordinate information may include information of coordinates of two diagonal vertices of the rectangular area.
In some embodiments, the acquiring a display image from a display interface of the terminal device every target duration when the first instruction is detected, and taking the acquired display image as a dynamic image frame includes:
when a first instruction is detected, acquiring a display image from a display interface of the terminal equipment every target time length;
and adjusting the resolution of the display image to a preset resolution, and taking the display image after the resolution adjustment as a dynamic image frame.
In some application scenarios, the definition requirement of a user on a dynamic image is not high, and the image resolution of a display image of a display interface is often high, so that the resolution of the display image can be adjusted to compress the size of the display image, and a dynamic image frame more meeting the user requirement is obtained, thereby avoiding the overlarge size of a subsequently generated dynamic image.
In some embodiments, the acquiring a display image from a display interface of the terminal device every target duration when the first instruction is detected, and taking the acquired display image as a dynamic image frame includes:
step S301, when a first instruction is detected, identifying a target type and/or a scene type corresponding to a current display image, wherein the current display image is an image displayed in the display interface when the first instruction is detected;
step S302, determining the target duration according to the target type and/or scene type in the current display image;
step S303, acquiring a display image from the display interface every target duration, and taking the acquired display image as a dynamic image frame.
In this embodiment, the target category may include a category of a target object in the currently displayed image. The target category and the scene category may be predetermined by a user according to an actual application scene.
For example, the target category may also include one or more of a stationary object, a slow moving object, a fast moving object, and the like, and for objects with different moving speeds, different target time lengths may be used, for example, the target time length corresponding to the stationary object in the target category is longer than the target time length corresponding to the slow moving object in the target category, and the target time length corresponding to the slow moving object in the target category is longer than the target time length corresponding to the fast moving object in the target category. Specifically, in a specific application scenario, if the object type in the currently displayed image includes an animal with a fast running speed, such as a cat, a dog, a horse, etc., the object duration may be made smaller, so as to shorten a time interval of acquiring time of each dynamic image frame, so as to improve a frame rate of the dynamic image, and ensure that content of the animal in a subsequently generated dynamic image can have a better display effect.
By the embodiment, the target duration can be determined according to the target type and/or the scene type in the currently displayed image, so that the frame rate of the dynamic image can be dynamically adjusted according to a specific application scene, and the waste of storage space can be avoided while the presentation mode of the content in the generated dynamic image meets the user's desire.
In the embodiment of the application, when a first instruction is detected, a display image is acquired from a display interface of the terminal equipment every other target duration, the acquired display image is used as a dynamic image frame, and the dynamic image frame for manufacturing the dynamic image can be acquired from the display interface of the terminal equipment; further, when the second instruction is detected, a dynamic image is generated according to the sequence of the acquisition time of each dynamic image frame and each dynamic image frame, at this time, the dynamic image can be obtained according to the display content of the display interface of the terminal device within a period of time, video recording and reprocessing are not needed, the time for making the dynamic image is shortened, the frame rate of the dynamic image can be flexibly adjusted by adjusting the target time and the like, for example, the size of the dynamic image can be reduced by adjusting the target time in some application scenes, so that a user can store and send the dynamic image, and the use experience of the user is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
