Abstract
An image preview method, apparatus, and terminal are disclosed to provide a technical solution in which a background blurring effect with respect to a current scene can be previewed in real time. A terminal device synchronously obtains preview images of a current scene from different angles in a dual-camera photographing preview mode by using a dual-camera module, calculates, in the preview images based on a phase difference generated by a distance and an angle of the dual-camera module, a depth of field of each pixel unit included in a preview image, obtains a foreground depth of field of a preset target area in the preview image, and determines, in the same preview image, an area including all pixel units having a depth of field beyond a range as a background area. The terminal device also performs blurring processing on the background area by using a preset blur coefficient, and outputs an image including the target area and a blurring-processed background area as a real-time preview image of the current scene.
