  • Publication number: 20240179399
    Abstract: An electronic device includes a display, a camera, and a processor. The processor receives, while displaying a preview image through the display based on at least portion of image frames obtained through the camera, an input with respect to a preset button. The processor switches to an auto framing mode in response to the photographing input. The processor identifies a first area matched to a subject captured by the camera, and a second area including a preset portion of the subject in the first area. The processor, based on predicting a moving direction of the subject in the image frames by a position of the second area in the first area, displays the preview image by performing cropping with respect to at least one of the image frames.
