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.
