Abstract
A method, system, and computer program product for an image capturing device having at least two cameras to obtain a focus point of a current scene. The method includes in response to performing a focus procedure via at least one camera of the image capturing device, determining whether a focus point has been found. The method further includes, in response to determining the focus point has not been found: (1) adjusting a number of focus scan steps of an auxiliary focus procedure utilized by only the at least one auxiliary camera and (2) performing the auxiliary focus procedure using the adjusted number of focus scan steps. The method further includes determining whether the focus point has been found, and in response to determining the focus point has been found, automatically synchronizing, to a main lens of the main camera, a current position of the lens of the at least one auxiliary camera.
