ABSTRACT:
An AF camera system for automatically controlling an objective lens for focusing an object includes a focus detector for generating a defocus data DF carrying information of a defocus amount and a defocus direction based on a focus condition of an object to be focused through an objective lens detected in a detection cycle, an infocus detector for detecting an infocus condition based on the defocus data, a lens driver for driving the objective lens based on the defocus amount and defocus direction carried in the defocus data DF when the infocus detection means did not detect the infocus condition; and a control for controlling the focus adjustment based on defocus data and/or the detection of the infocus condition detected by the infocus detection means.
