摘要： An image sensing system comprises photoelectric conversion element array which responds to the light from a subject and produces charges responding to the quantity of incident light, storage parts temporarily storing the charges produced by the array and a shift register which receives and outputs the charges in the storage parts. A first gate is installed between the array and the storage parts and a second gate is installed between the storage parts and the shift register. The storage time of the charges and the like can be controlled by controlling the first and the second gates by a control circuit. Then, when the subject is of high luminance, the charges are stored into the storage parts with the array and storage parts connected intact to each other by putting the first gating means in the ON state, and the completion of integration thereof is performed by putting the first gate in the OFF state. Also, when the subject is of low luminance, storage of charges is performed in the array with the first gate put in the OFF state, and a dark charges produced in the storage parts during that time is discharged before storing the charges of the above-mentioned arrays.

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.
