Description

This application claims priority to Chinese Patent Application No. 202311435092.1, filed with the China National Intellectual Property Administration on October 30, 2023 and entitled "GENERATION METHOD AND GENERATION APPARATUS FOR ANIMATION, AND ELECTRONIC DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of image processing technologies, and in particular, to a generation method and generation apparatus for an animation, and an electronic device. BACKGROUND With continuous development of terminal technologies, an increasing number of users start to use images to record their lives. For some satisfactory images, the user also wants to make an animation for playing and displaying. To meet this demand, a technology of generating an animation from an image has emerged. The user may combine a plurality of images from a local gallery, stitch the images together into an animation, and then share the animation to a social platform. The animation may also be used as a dynamic wallpaper for a desktop or a screensaver, thereby expanding sources of dynamic wallpapers on a terminal. When a terminal device generates an animation from an image, camera movements may be applied to the image for display, to improve image display effect in the animation. For example, the image in the animation may be displayed from left to right, from top to bottom, or with zooming effect. At present, when the terminal device generates the animation with camera movement display effect, the terminal device may process the image in the animation based on a preset camera movement direction. For example, if the preset camera movement direction is from left to right, the image is displayed in the generated animation in accordance with the camera movement direction from left to right. However, a plurality of images are usually added to the animation. In a conventional technology, the plurality of images can be displayed only in a fixed camera movement direction, which is not flexible enough in the use of camera movements, resulting in poor display effect of the animation. SUMMARY Embodiments of this application provide a generation method and generation apparatus for an animation, and an electronic device, so that a camera movement direction can be determined based on display content of an image, and a high-quality animation with harmonious camera movements can be generated, thereby improving display effect of the animation. According to a first aspect, a generation method for an animation is provided, including: obtaining a first image; determining a first camera movement direction based on display content of the first image; and generating the animation based on the first camera movement direction and the first image, where the first camera movement direction is a camera movement direction corresponding to the animation. According to the generation method for an animation provided in this embodiment of this application, a camera movement direction (denoted as a first camera movement direction) may be first determined based on display content of an image (denoted as a first image), and then the animation is generated based on the first camera movement direction and the first image. That is, the first image is displayed based on the first camera movement direction, thereby generating the animation. Because the camera movement direction is determined based on the display content of the image, the camera movement direction can be associated and matched with the display content of the image, and camera movements can be flexibly utilized based on the image content, so that a sense of image and immersion of the animation is enhanced and a high-quality animation with harmonious camera movements can be generated, thereby improving display effect of the animation. Because association and matching is implemented between the camera movement direction and the display content of the image and use of the camera movements is more harmonious and smoother, the generated animation has higher quality and a stronger sense of image. This improves display effect of the animation, thereby providing the user with coherent immersive experience, and improving visual experience of the user. Optionally, the first image may be obtained by an electronic device through photographing, or may be from the internet (for example, a social platform). Optionally, the first image may alternatively be obtained from another animation. The another animation may be, for example, a GIF image or a video. For example, the first image may be obtained by taking a screenshot of a video or by extracting a frame from a video. A specific source of the first image is not limited in this application. Optionally, a specific manner of "determining the first camera movement direction based on the image content" is not limited in this embodiment of this application. For example, a photographed subject in the first image may be recog
