  • Publication number: 20250191119
    Abstract: An electronic device and an image obtaining method applied to a first device includes generating a thumbnail of an original image and a preview image of the original image based on information about the original image, where a size of the thumbnail is a first size, a size of the preview image is a second size, the first size is less than the second size, and the thumbnail and the preview image are stored in a same module. When an application requests to access a target image of the original image, the target image is generated based on a relationship between a target size of the target image and the first size and/or the second size, and the target image is displayed.
