摘要： A focal point detection system for detecting the focus adjusting state of an image forming lens during its focusing operation on an object is disclosed. The system comprises a focus detection circuit which produces a detection output that varies with focusing of the lens on the object; a plurality of display elements are provided for display of the focusing state of the lens; and a display control circuit which enables the display elements to display a greater number of focusing states than the number of these display elements through selective combinations of these elements on the basis of the output of the focus detection circuit. The system is capable of displaying intermediate focusing states such as a slightly near-focus state, a slightly far-focus state, and the like in addition to in-focus, near-focus, and far-focus states, so that the focusing state can be displayed stepwise in a detailed manner.

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 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.
