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： By providing a liquid crystal cell nearly at the position of the clear vision of the view finder optical system together with a means for masking the display part of the liquid crystal cell the noise appearing on the boundary between the display part and the object view field is eliminated while the invasion of dusts is avoided, whereby further by means of the liquid crystal cell the alarm for the improper exposure, the alarm of the consumption of the power source battery and so on are displayed besides the photographic informations.

摘要： A distance detecting device utilizable in an optical device such as a camera and the like requiring focusing operation of the optical system thereof. The detecting device enables the adjustment of the relative optical length between the group of light receiving elements arranged adjacent to the image forming plane of the object to be measured by the distance measuring optical system and the distance measuring optical system. The detecting device is characterized in that the output of each of the light receiving elements of the groups is introduced through an electric switching device for effecting the time seriation of the outputs of the respective light receiving elements into a common signal processing circuit, so as to adjust the relative optical length by means of a motor provided in responsive relationship to the output of the signal processing circuit thereby permitting the focusing of the image on the groups of the light receiving elements to be made to the most proper condition.

摘要： In the system disclosed, a cylindrical lens or mirror compresses the image of an object illuminated by a beam, and a movable mirror coupled to the lens barrel of a lens system reflects the compressed image onto the dividing line between two photosensors. The unbalance between the outputs of the photosensors indicates the defocus of the lens system. A servo responds to the unbalance to refocus the system by moving the lens barrel and the mirror until the photosensor outputs are balanced.

摘要： This invention relates to a system for automatic focus adjustment of an optical system particularly adapted for use in a photographic camera which utilizes non-linear resistance versus illumination response characteristics which are prominent in photoconductive cells such as cadmium sulfide and cadmium selenide cells. In one embodiment, a pair of photoconductive cells, one of which has a photoconductive surface having elongated side portions which contact the electrodes along the length of the elongated side portions and another cell which has an elongated photoconductive surface and shortened end portions and which contact the electrodes only at the shortened end portions, are arranged so that portions of an image-forming light beam entering through an objective of the camera are directed to the photoconductive surfaces on which similar real images of an object are formed. The objective includes at least one lens member movable for focusing associated with an automatic focus control mechanism operative in response to variation of an electrical output signal of the photoconductive cell assembly produced when the degree of sharpness of the image on each of the photoconductive surfaces is varied as the focussing member is moved for focussing purposes with respect to the photoconductive cell assembly.
