    摘要: Disclosed is a focus detecting system in which first and second signals corresponding to image forming states at first and second positions each almost at the same distance before and behind a predetermined focal plane of an image forming optical system are obtained. A third signal corresponding to an image forming state at a third position different from the first and the second positions is also obtained. The in-focus state of the image formed by the image forming optical system is detected on the basis of a first comparison signal obtained by comparing the first and the second signals with each other, a second comparison signal obtained by comparing the first and the third signals with each other and a third comparison signal obtained by comparing the second and the third signals with each other.

    摘要: In the disclosed TV camera, a focus detecting device detects the focus of the image optical system by evaluating the image of the object whose image is to be picked up, on the basis of the picture image signal obtained at a predetermined position in the image pick up surface of the image pick up device. At least a part of the image to be evaluated is formed at a position within the scanning area of the image pick up device but outside of the effective image pick up area for TV signals. The image is evaluated on the basis of the picture image signal obtained at this position to detect the focus.

    摘要: In the disclosed element, a number of line shaped sensors each includes a plurality of P-N junctions each of which accumulates a charge corresponding to the amount of light incident thereon. A number of registers, one for each sensor, each defines addresses coupled to respective P-N junctions of the corresponding sensor to have the charge accumulated on each P-N junction transferred to the respective address in each register so that time sequential signals can be obtained from each register. A collection register has an address coupled to each of the other registers to store the time sequential output signals so that the stored signals can be read out sequentially. A gate arrangement connecting the output of the first registers to each address controls the time interval during which the time sequential signals of the first registers are transferred to the accumulating register.

    摘要: In the device disclosed, an image formed by an optical system is scanned by an image sensor composed of independently arranged photoelectric transducing elements to produce an image scanning signal. A detecting circuit detects the variation of the brightness between the adjacent image elements as a measure of the sharpness of the image and the focus of the optical system. The focus detection accuracy is improved by non-linear transformation of the brightness variation signal with a non-linear transformation circuit that weighs the brightness variation signal on the basis of the signal level.

    摘要: A camera system has a camera main body which has a focus detecting device for detecting a focusing state of a photographic optical means in a photographic lens assembly mounted, a display responsive to an output signal from the focus detecting device, and a contact for transmitting the output signal of the focus detecting device to outside of the camera main body. In this camera system, the camera main body are usable with a photographic lens assembly of first type which has an automatic focusing device which is capable of automatically focusing the photographic optical system on the basis of the output signal from the focus detecting device, and with a photographic lens assembly of second type which does not have such an automatic focusing device. When the camera main body is combined with the photographic lens assembly of first type, automatic focusing of the photographic optical system may be performed. When the camera main body is combined with the photographic lens assembly of second type, manual focusing may be performed utilizing a display at the side of the camera main body for displaying the focusing state.
