Abstract
A multi-camera zooming method includes: during zooming from an i-th magnification range to an adjacent j-th magnification range, a j-th camera corresponding to the j-th magnification range is selected from n cameras, 1≤i≤n and 1≤j≤n; when the j-th camera is in a non-operating state, a transition camera and a target camera are determined; the transition camera is set as a camera configured to acquire a preview image; the target camera is unloaded from an operating state to the non-operating state and the j-th camera is loaded from the non-operating state to the operating state; and the camera configured to acquire the preview image is switched from the transition camera to the j-th camera.
