Abstract: A device produces a dolly zoom effect with automatic focal length adjustment. The device uses a camera to capture an initial image including at least a foreground object and a background. The device includes a size tracking circuit to identify the size of the foreground object in the initial image. The device further includes a focal length control circuit. The focal length control circuit calculates an adjusted focal length of the camera to maintain the size of the foreground object in subsequently captured images.

Abstract: A system produces a dolly zoom effect by utilizing side view information. The system first captures a main image at a main location. The main image includes at least a foreground object of a given size and a background. The system calculates one or more side view locations based on a zoom-in factor to be applied to the background and an estimated size of the foreground object. The system then guides a user to capture one or more side view images at the one or more side view locations. The foreground object of the given size is superimposed onto a zoomed-in background. Then the side view information is used by the system to perform image inpainting.
