摘要： A camera with an automatic focusing device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a brightness distribution is obtained so as to detect a rough focusing condition in each zone, thereby producing a plurality of rough focusing condition data. Based on the result of the rough focusing condition data, one zone is selected. Furthermore, a precise focusing condition is detected in the selected zone based on the light contained in the selected zone, so as produce a precise focusing condition data. Based on the precise focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition.

摘要： An AF autofocus camera system for automatically controlling an objective lens for focusing an object including a focus detector for generating defocus data 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 at a detection cycle, and a focus condition memory for storing defocus data obtained in a present detection cycle, a previous detection cycle, and a cycle before the previous detection cycle. The system further includes first and second infocus detectors for detecting the infocus condition based on the defocus data itself and the average of the defocus data, respectively. First and second lens drive controllers are provided for driving and stopping the objective lens responsive to the first and second infocus detectors, respectively. The system further includes a selector for selecting the second infocus detector and the second lens controller to be operative where none of the defocus data is within an acceptable range or tolerance range so as to be considered as an infocus condition and the defocus direction of the defocus data obtained in the present and previous detection cycles show opposite directions.
