Description

Technical Field

[0001] This invention relates to the field of animation technology, and in particular to a method for generating animation data, an electronic device, and a storage medium. Background Technology

[0002] As users demand a higher level of product experience, more and more electronic devices are equipped with displays, which can show static or dynamic images and enhance the user's intuitive perception.

[0003] When a user wants to display an animation on an electronic device's screen, they can use a terminal device to transmit the animation content to the electronic device, which will then display the corresponding animation. In some scenarios, to reduce the amount of data transmitted, the terminal device does not transmit all image frames when transmitting animation content to the electronic device; it only transmits a subset of key frames. The electronic device then uses these key frames, along with animation generation methods such as object recognition and optical flow tracing, to fill in the missing frames and generate the animation data.

[0004] However, these existing animation generation methods are quite complex, and for some electronic devices, the limited computing resources make it difficult to implement these methods. Summary of the Invention

[0039] Figure 4 This is a flowchart of a method for generating animation data according to an embodiment of this application, such as... Figure 4 As shown, the method for generating animation data is applied in electronic devices. Depending on different needs, the order of the steps in this flowchart can be changed, and some steps can be omitted.

[0040] Step S01: Obtain the start frame image and the end frame image.

[0041] In some embodiments of this application, the electronic device can acquire a start frame image and an end frame image from a terminal device. For example, a user can select an animation corresponding to a target image expression in an application on the terminal device and preview the animation in real time. When the user wants to display the animation on the screen of the electronic device, they can operate the terminal device to transmit the animation to be displayed to the electronic device, controlling the electronic device to display the corresponding animation.

[0042] In some scenarios, to reduce the amount of data transmitted, when a terminal device transmits animation content to an electronic device, it does not need to transmit all the image frames corresponding to the animation. For example, the terminal device can send the first and last frames of the animation to the electronic device; the electronic device can use the first frame as the start frame and the last frame as the end frame, and then generate the intermediate frames corresponding to the animation based on the start and end frames to obtain and display the animation.

[0043] For example, for some complex animations, the terminal device can send the first frame image, key frame image, and last frame image corresponding to the animation to the electronic device; the electronic device can use two adjacent frames in the first frame image, key frame image, and last frame image as the start frame image and end frame image, respectively, and generate intermediate frame images between adjacent frames one by one using the method provided in this application, and finally obtain and display the complete animation based on the first frame image, key frame image, last frame image, and intermediate frame images corresponding to each adjacent frame.

[0044] Step S02: Determine whether the number of initial display pixels in the starting frame image and the number of initial display pixels in the ending frame image are inconsistent. If the number of initial display pixels in the starting frame image and the number of initial display pixels in the ending frame image are consistent, proceed to step S04; if the number of initial display pixels in the starting frame image and the number of initial display pixels in the ending frame image are inconsistent, proceed to step S03.

[0045] In some embodiments of this application, the start frame image and / or end frame image are displayed as pixels on an electronic device. When the electronic device plays an animation, it needs to play from the start frame image to the end frame image, which can be achieved by gradually changing the initial display pixels in the start frame image to the initial display pixels in the end frame image.

[0046] If the number of initial display pixels in the starting frame image and the number of initial display pixels in the ending frame image are inconsistent, the process executes step S03, which can supplement virtual display pixels in the starting frame image or the ending frame image to make the number of display pixels contained in the starting frame image and the ending frame image the same.

[0047] If the number of initial display pixels in the starting frame image is the same as the number of initial display pixels in the ending frame image, the process executes step S04 to determine the one-to-one mapping relationship between the display pixels in the starting frame image and the display pixels in the ending frame image.

[0048] Step S03: Add virtual display pixels to the starting frame image or the ending frame image so that the number of display pixels contained in the starting frame image and the ending frame image is the same.

[0049] In this embodiment of the application, if the number of initial display pixels in the starting frame image and the number of initial display pixels in the ending frame image are inconsistent, for the frame image with fewer initial display pixels, virtual display pixels are obtained by randomly copying pixels from the original frame image, so that the number of pixels in the starting frame image is the same as the number of pixels in the ending frame image.

[0050] In some embodiments of this application, virtual display pixels are added to the starting frame image or the ending frame image to make the number of display pixels contained in the starting frame image and the ending frame image the same. This includes: when the first number of initial display pixels in the starting frame image is less than the second number of initial display pixels in the ending frame image, determining a first difference between the second number and the first number; and adding virtual display pixels of the first difference to the starting frame image so that the sum of the number of initial display pixels and virtual display pixels in the starting frame image is equal to the second number of initial display pixels in the ending frame image.

[0051] The coordinates of the virtual display pixels overlap with the coordinates of the initial display pixels in the image. One initial display pixel can have 0, 1, or more virtual display pixels superimposed on it.

[0052] Since the coordinates of the supplementary virtual display pixels overlap with the coordinates of the initially displayed pixels in the image, they do not affect the actual display of the image.

[0053] By randomly copying the initial display pixels from the starting frame image to supplement the virtual display pixels of the first difference, the transition of the screen during animation playback can be made smoother, and the overall effect can more naturally present the change from the starting frame image to the ending frame image.

[0054] For example, the starting frame image is a circle, and the ending frame image is a square. The initial number of display pixels in the starting frame image is 80, and the second number of initial display pixels in the ending frame image is 100. Since the first number is less than the second number, the first difference between them is 20. At this point, 20 virtual display pixels can be added to the circular starting frame image, making the sum of the initial display pixels and virtual display pixels in the starting frame image equal to the second number of initial display pixels in the ending frame image. The coordinates of these 20 virtual display pixels in the starting frame image can overlap with the coordinates of the 20 initial display pixels out of the 80 initial display pixels in the starting frame image.

[0055] In some embodiments of this application, virtual display pixels are added to the starting frame image or the ending frame image to make the number of display pixels contained in the starting frame image and the ending frame image the same. The method further includes: when the first number of initial display pixels in the starting frame image is greater than the second number of initial display pixels in the ending frame image, determining a second difference between the first number and the second number; and adding virtual display pixels of the second difference to the ending frame image so that the sum of the number of initial display pixels and virtual display pixels in the ending frame image is equal to the first number of initial display pixels in the starting frame image.

[0056] For example, the starting frame image is a circle, and the ending frame image is a square. The initial number of display pixels in the starting frame image is 100, and the second number of initial display pixels in the ending frame image is 80. The first number is greater than the second number, resulting in a second difference of 20. Twenty virtual display pixels are added to the square ending frame image, such that the sum of the initial display pixels and virtual display pixels in the ending frame image equals the second number of initial display pixels in the starting frame image. The coordinates of these 20 virtual display pixels in the ending frame image can overlap with the coordinates of the 20 initial display pixels out of the 80 initial display pixels in the ending frame image.

[0057] Step S04: Determine the one-to-one mapping relationship between the display pixels in the starting frame image and the display pixels in the ending frame image.

[0058] In some embodiments of this application, in order to ensure a smooth transition from the starting frame image to the ending frame image during animation playback, it is necessary to determine a one-to-one mapping relationship between the display pixels in the starting frame image and the display pixels in the ending frame image. Specifically, a one-to-one mapping relationship is established between randomly selected display pixels in the starting frame image and the display pixels in the ending frame image.

[0059] Step S05: Based on the preset interpolation algorithm and the coordinates of each corresponding display pixel in the starting frame image and the coordinates in the ending frame image, generate multiple intermediate frame images.

[0060] In this embodiment of the application, after determining the one-to-one mapping relationship between the display pixels in the starting frame image and the display pixels in the ending frame image, multiple sets of corresponding display pixel coordinates in the starting frame image and coordinates in the ending frame image can be obtained. Based on a preset interpolation algorithm and the coordinates of each set of corresponding display pixels in the starting frame image and coordinates in the ending frame image, multiple intermediate frame images are generated.

[0061] Specifically, based on the interpolation algorithm and the coordinates of each group of corresponding display pixels in the starting frame image and the ending frame image, the coordinates of the display pixels in the intermediate frame are generated; and the intermediate frame image is generated based on the coordinates of the display pixels in the intermediate frame corresponding to each group of corresponding display pixels.

[0062] In some embodiments of this application, the interpolation algorithm is a linear interpolation algorithm or a nonlinear interpolation algorithm. Indicatively, the interpolation algorithm described above can be any one of the following algorithms: sine interpolation algorithm, polynomial interpolation algorithm, slow-in slow-out interpolation algorithm, cubic spline interpolation algorithm, Bézier curve interpolation algorithm, etc., and this application does not limit it in this regard.

[0063] In some embodiments of this application, assuming the starting frame image is frame1 and the ending frame image is frame15, after the electronic device acquires frame1 and frame15, it adjusts frame1 or frame15 according to the first number of initial display pixels in frame1 and the second number of initial display pixels in frame15, so that the number of display pixels contained in frame1 and frame15 is the same. Then, it determines the one-to-one mapping relationship between the display pixels in frame1 and the display pixels in frame15. Based on a preset interpolation algorithm and the coordinates of each corresponding set of display pixels in frame1 and in frame15, multiple intermediate frame images frame2 to frame14 are generated. Animation data is generated based on frame1, multiple frames2 to frame14, and frame15.

[0064] For example, based on the coordinates (x1-i, y1-i) of the corresponding display pixel in frame1 and (x15-i, y15-i) in frame15, a pre-set interpolation algorithm is used to generate the coordinates of the corresponding display pixels in 13 intermediate frame images from frame2 to frame14, such as coordinates (x2-i, y2-i), (x3-i, y3-i), ..., (x14-i, y14-i), to achieve a smooth transition effect, where i is a natural number.

[0065] Then, the corresponding intermediate frame images can be generated based on the coordinates of the display pixels corresponding to the intermediate frame images frame2 to frame14. For example, based on the coordinates of the corresponding display pixels in the i-th group, the coordinates (x2-i, y2-i) of a display pixel in the intermediate frame image frame2 can be calculated. Assuming there are 80 corresponding display pixels, the intermediate frame image frame2 can be determined based on the coordinates (x2-1, y2-1), (x2-2, y2-2), (x2-3, y2-3), ..., (x2-80, y2-80).

[0066] In this embodiment of the application, after generating multiple intermediate frame images, the start frame image, multiple intermediate frame images and the end frame image can be stored in the electronic device in a preset storage format.

[0067] Step S06: Generate animation data based on the starting frame image, multiple intermediate frame images, and the ending frame image.

[0068] In some embodiments of this application, based on the examples listed above, during the process of generating animation data from a start frame image, multiple intermediate frame images, and an end frame image, an easing-in / easing-out interpolation algorithm can be used to generate the coordinates of the display pixels in the multiple intermediate frames, controlling the speed at which the display pixels in the start frame image move to the corresponding display pixels in the end frame image, thus achieving a natural easing-in / easing-out animation rhythm. For example, a circular start frame image can be slowly transitioned to other arbitrarily shaped intermediate frame images, finally presenting a square end frame image.

[0069] In some embodiments of this application, after generating animation data based on a start frame image, multiple intermediate frame images, and an end frame image, the method for generating animation data further includes: storing the animation data; and playing the animation data when a preset trigger condition is met. The preset trigger condition includes any one of turning on the electronic device, charging the electronic device, or other conditions.

[0070] In some embodiments of this application, the method for generating animation data further includes: when a preset trigger condition is met, checking whether a preset flag field is a first identifier, where the first identifier can be represented as 1, true, or other identifiers; if the flag field is determined to be the first identifier, playing the animation data; and after playback, setting the preset flag field to a second identifier, where the second identifier can be represented as 0, false, or other identifiers to avoid repeated playback. Then, after waiting for a preset duration, resetting the flag field to the first identifier again to execute the next animation playback.

[0071] Through the above steps S01 to S06, animation data can be generated based on the start frame image and the end frame image, without needing to receive all the image frames contained in the animation data.

[0072] While some algorithms for generating intermediate frames include those that use interpolation to generate intermediate frames based on keyframes, these methods perform interpolation from the perspective of the overall image of the keyframes. This process is complex and requires significant computational resources, making them unsuitable for electronic devices with limited computing resources.

[0073] Compared to these algorithms, the method for generating animation data provided in this application starts from the dimension of pixels. By supplementing the display pixels of the start frame image and the end frame image, and establishing a one-to-one correspondence between the display pixels of the start frame image and the end frame image, the process of calculating intermediate frames is simplified from interpolation calculation between images to interpolation calculation between the coordinates of corresponding display pixels. This greatly simplifies the calculation difficulty of intermediate frames, making the method provided in this application applicable to electronic devices with limited computing resources, and solving the problem of difficulty in generating animation data on electronic devices with limited computing resources.
