摘要： In a automatic focussing camera a focusing lens is moved toward the in-focus position while performing a defocus detection while the defocus amount of the photographic lens is large so as to repeatedly judge the error of the position of the focusing lens. When the defocus amount is decreased lower than a predetermined value the lens is stopped and further defocus detection is made for effecting an accurate defocus detection. The error of the defocus detection is small partly because the defocus detection is made while the lens is stopped, and partly because the defocus detection is made under such a state that the error is smaller than the predetermined value.

Each array comprises photoelectric converting elements arranged to receive the object image and accumulation cells coupled to each photoelectric converting element for accumulating charges produced from the photoelectric converting element. A buffer memory cells are coupled respectively to the accumulation cells for temporarily storing the accumulated charges shifted from the accumulation cells in response to the completion of the charge accumulation in each array. A shift register is provided to receive accumulated charges from the buffer memory cells in every one of the arrays after all the arrays complete the charge accumulation. The accumulated charges stored in the shift register are then sequentially outputted.

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： There is provided an automatic focus control device for use in a camera system comprising a focus detection control means for continuously driving a motor from the time when it is judged that a focus condition of a photograph lens can not be detected until it is judged that the focus condition can be detected, and a rotation number control means for controlling the rotation speed of said motor driven by said focus detection control means in accordance with a constant data designating a relationship between the rotation number of said motor and a unit of a defocus value. Accordingly, the moving speed of said photograph lens is controlled in accordance with defocus variation during the movement of said photograph lens, resulting in that the infocus position of the object can be detected by a low contrast search without overrunning the infocus position, even though the object is positioned far from an available range of the focus detection.
