摘要： A viewfinder optical system for a real-image type viewfinder has a positive objective lens system for obtaining a finder-image, and an erecting optical system for converting the finder-image into an erected image. The erecting system includes a mirror for deflecting an optical axis of the objective lenses, and at least a part of the mirror is formed as a light-transmitting area. The viewfinder optical system further comprises an ocular lens for viewing the finder-image, and an optical system for optically producing an information pattern, such as a viewing-field-frame, to be superimposed on the finder-image. The projecting system includes a projecting lens which focuses and forms the frame-pattern on an image-forming plane, defined by the objective lens system, through the light-transmitting area of the mirror, so that the frame-pattern is superimposed on the finder-image.

摘要： A real-image finder comprises an objective optical system which forms an image of an object to be viewed; a field frame member located on a primary image forming plane on which the image formed by the objective optical system is formed; an ocular optical system through which the object image formed on the primary image forming plane; and an image erecting optical system which erects the object image formed by the objective optical system. The transparent members are provided on the front and rear surfaces of the field frame, and the thickness of the transparent members are determined so that if a foreign matter sticks to the end surfaces of the transparent members that are opposite to and located away from the field frame member, no foreign matter can be viewed through the ocular optical system.

摘要： Disclosed is a range finder system which includes a virtual image type first optical system for observing an object, and a second optical system for electronically capturing image of at least a part of the object. The range finder system is provided with an LCD (liquid crystal display) which displays the image captured by the second optical system. The image displayed on the liquid crystal display is directed to the virtual image type finder optical system, and the image as displayed on the LCD is combined with the image observed through the first optical system. Thus, two images are observed by a photographer as superimposed. A display controller controls the LCD so that the degree of coincidence of the superimposed images is varied in the direction of a base length based on an object distance information.

摘要： A view finder device has a Poro prism and a first optical system facing an emergent plane of the Poro prism. The first optical system is positioned beside the Poro prism and opposite to a recording medium passage through which an electro-developing recording medium is moved. A relay optical system is provided behind the recording medium passage, so that the eye point of the view finder is separated from the first optical system. A second optical system is provided behind the relay optical system, so that the image formed by the relay optical system is observed. Since the electro-developing recording medium can be moved between the first optical system and the relay optical system, the finder optical system can be disposed at a lower position.
