    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.

    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 improved focus detecting apparatus comprises a photographic lens, focus adjusting apparatus for driving the photographic lens which has been placed on an initial focusing position to an in-focus position, an auxiliary light emitting apparatus for emitting an auxiliary light and a switch for selecting whether the focus adjustment should be carried out with the auxiliary light emitted or the focus adjustment should be carried out without the auxiliary light. The initial focusing position of the photographic lens can be switched dependent on whether the auxiliary light is emitted or not.

    摘要： An automatic focus adjusting apparatus of a camera comprises three CCD sensors receiving light from an object, a focus detecting apparatus for outputting a focus signal indicative of the focusing state of a photographic lens based on output data from the respective CCD sensors, a calculating apparatus for calculating an amount of driving the photographic lens based on the focus signal, a selector for selecting one of the three CCD sensors, a correcting apparatus for correcting the amount of driving calculated based on the output data from the selected CCD sensor, and a driving apparatus for driving the photographic lens to an in-focus position based on the corrected driving amount. An error in foucs detection incidental to the driving of the lens can be corrected based only on the data from one CCD sensor selected by a selector, so that the focusing error on a moving object can be eliminated in a simple manner.
