Methods and imaging devices are disclosed for reducing defocus events occurring during autofocus search operations. For example, one method includes capturing a plurality of frames depicting a scene with an imaging device, selecting a portion of the scene of at least one frame that corresponds to an object of the scene, and detecting a change in the scene. The method further includes detecting a distance between the object and the imaging device for each of the plurality of frames, determining a lens position for each frame based on the determined distance of each frame and moving a lens toward the lens position of each frame while the scene continuously changes. The method also includes determining the scene is stable and initiating an autofocus search operation based on the determination that the scene is stable. |
