摘要： In an automatic continuous focusing device, two detected images of an object formed by a distance detection optical system with a relative distance therebetween associated with the object distance are scanned, the obtained scanning signals are quantized to generate quantized picture element data, the relative distance between the two detected images is detected on the basis of the quantized picture element data, and an imaging optical system to be focused on the object is controlled according to the detection result. The device also provides for invalidating the control of the imaging optical system when the results of detection of the quantized condition of the scanning signals indicate that the quantized condition of the scanning signals for at least one of the two detected images is not sound or reasonable.

摘要： A liquid crystal cell is provided within a camera viewfinder. In the cell, a liquid crystal is sandwiched between a resistance layer mounted on a substrate and another substrate-mounted layer which may be either resistive or conductive. Suitable means mask at least the end portions of the display of the liquid crystal cell. In operation, voltages corresponding to photographic conditions are applied to the layers to produce analog data indicative of photographic conditions.

摘要： In the disclosed liquid crystal display system, one of two opposing base plates that sandwich an electrooptic liquid crystal between them is divided into separate electrodes or constitutes a homogeneous transparent resistance. A source of power energizes this electrode so as to produce a gradient or stepped voltages between the divisions, and a data voltage is applied to the other electrode so that one section of the sandwiched electrodes can effect light differently than the other sections and thereby display information.

摘要： A camera provided with automatic focus detector is disclosed. The automatic focus detector drives a photographing lens toward the in-focus position by lens driving means in accordance with focus detection signal repeatedly put out from focus detecting means. The present invention is directed to improvement in focusing operation of such camera. Said lens driving means is allowed to drive the photographing lens toward the in-focus position only when the focus detection information signal continues to be constant longer than a predetermined time length. At the same time, the driving state of the photographing lens by said lens driving means is detected and display means is controlled by the detection signal to display the state of focusing now present.
