Abstract: An image capturing device includes an optical zoom lens module, a processing module, and a motion sensing module. The optical zoom lens module captures an image corresponding to a first field of view according to a preset parameter. An auto-framing unit of the processing module defines a second field of view according to the position of a main object in the image corresponding to the first field of view, and the second field of view is smaller than the first field of view. The processing module controls the optical zoom lens module to capture images corresponding to the second field of view. When the motion sensing module detects that a suspected object enters the first field of view, it transmits a switching signal to the processing module, which controls the optical zoom lens module to capture the image corresponding to the first field of view.
