摘要: A video camera has an automatic focusing system provided with a focus detecting section for calculating and outputting a focus signal corresponding to a focus condition of an picked-up image from a video signal produced by an image pickup element. Either the image pickup element or a focusing lens in a photographic lens is oscillated back and forth of its present position, as needed, to detect an in-focus direction at the moment. The focusing lens is moved in the in-focus direction up to a position at which an optimum focus condition is obtained.

摘要: A video camera with an automatic focusing device includes a pre-process unit for eliminating a direct current component from a signal of the video camera and controlling the obtained signal so that the amplitude thereof can be at a constant level, which is disposed at the preceding stage of a signal processing unit for operating the focusing condition of an object from the signal of the video camera. An amplitude of a video signal to be inputted to the signal processing unit can be largely suppressed, thus providing a largely simplified circuit structure of a signal processing unit.

摘要: The amount of slant of an entire video camera in the vertical direction is detected by a slant detector by detecting a horizontal and vertical signal quantity or by a mechanical vertical direction detector and a memory controller reads out the video signal while controlling the address of the memory so as to correct the slant of the video signal stored in the memory depending on the slant amount, and since the memory is composed of two memory systems the slant may be always corrected for a real time in moving picture, thereby presenting a stable video output.

摘要: An automatic focusing apparatus uses an image signal provided by a lens system of a camera for focusing the taking lens system. The apparatus includes: a lens system; a pickup element for converting the optical image of an object formed by the lens system into a corresponding electric signal; a signal processing circuit which processes the output signal of the pickup element to provide two focus signals corresponding to the respective quantities of horizontal and vertical high-frequency components of the object in an image plane; a lens driving mechanism for driving the lens system; and a control unit for controlling the lens driving mechanism according to the two focus signals to focus the lens system. Preferably, the apparatus further includes: a detector for detecting the condition of the object or the viewing conditions and a changeover circuit for changing over the characteristics of the signal processing circuit on the basis of the output of the detector. The additional use of information about the vertical direction enables the focusing of the lens system for any object including a horizontal line. Since the characteristics of the signal processing circuit are changed selectively according to the condition of the object or the viewing conditions, a stable and accurate focusing operation can be achieved regardless of the variation of the condition of the object.

摘要: A zoom lens driving apparatus always detects a position of an image magnification varying lens section, and drives the image magnification varying lens section in accordance with a preset relationship between the position of the image magnification varying lens section and a zoom driving speed in such a manner that the driving speed becomes higher on one side, where the focal length of the zoom lens corresponding to the position of the image magnification varying lens section is small, than on another side where the focal length is large. Accordingly, the amount of focal shift, which in the zoom lens of the inner focusing system would otherwise abruptly increase with increasing focal length, is significantly suppressed, so that an auto focus adjusting mechanism or a focus correcting device effective during zooming, provided in the zoom lens, can function satisfactorily as to follow the focal shift of the zoom lens, whereby the lens control of a superior response can always be achieved.

摘要: A solid-state imaging apparatus having color separation filters is provided which produces a signal with reduced chrominance and luminance moire and thereby improves resolution, and the spectral characteristics of the color filters for the solid-state imaging apparatus are so set that when the spectral characteristic of each color filter is multiplied by a prescribed coefficient, the sum of four or two horizontally adjacent pixels becomes approximately equal between two vertically adjacent lines. A coefficient multiplying circuit multiplies an output signal from each color filter by the prescribed coefficient, and signal processing is performed.
