摘要： A solid state image pickup device having a matrix array of resolution cells from which the charges are successively transferred to produce a video signal is provided with means for holding the charges for the two resolution cells adjacent to each other in a direction corresponding to the vertical scanning line for the television signal to permit the charges from the aforesaid adjacent resolution cells to be interrelated with each other. In this manner the resolving power in the vertical direction is improved.

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. A signal forming circuit detects the difference between the outputs of transducing elements and adds the differences to produce a comparator signal when a predetermined relationship is reached between the sharpness indication and the addition signal. An indicator indicates that the focusing condition cannot be discerned in response to the comparison signal and a control inhibits the output of the detection circuit to the indicator prior to the addition signal.

摘要： Disclosed is a TTL (Through-The-Lens) type focus detecting device for use in an interchangeable lens-equipped camera, in which a plurality of lenslets are positioned at or near the prescribed focal plane of the objective lens, each of the lenslets is associated with two or more pairs of photosensitive elements. Upon attachment of an objective lens to the camera body, one of the pairs of photosensitive elements for each lenslet is automatically selected to operate on the basis of the dimensions of the used objective lens. The outputs of the selected pairs of photosensitive elements for all the lenslets are processed to detect whether or not a positional difference between two images of an object formed with light beams from the objective lens at respective virtual exit pupils lying in almost symmetry with respect to the optical axis thereof is present, whereby the detection of whether or not the objective lens is in-focus is indicated.

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.
