Abstract: A digital camera enables high-speed zooming operation without use of a zoom lens. Light originating from a fixed-focal-length lens is split into two beams by a beam splitter, to thus form respective images on a first image sensor and a second image sensor. The first image sensor and the second image sensor are equal to each other in terms of the number of pixels, but differ from each other in terms of a pixel size. The first image sensor acquires a wide image, and the second image sensor acquires a telephotography image. An output is produced by means of switching between the first image sensor and the second image sensor, in response to zooming operation. When the image from the first image sensor is recorded, focus detection is performed by use of an image signal from the second image sensor, to thus effect automatic focusing.

Abstract: A photographic film strip in the form of a length of photographic film has a pre-exposed area and an unexposed area. The pre-exposed area is continuous and extends along one edge of the strip between ends of the strip. The unexposed area is also continuous and has a length suitable for making multiple single exposure frames with adjacent frames being separated by a frame line. Upon development the film, an image formed by the pre-exposed section of each print will extend between opposite edges of prints formed by individual frames without the need to preregister the film in a camera The pre-exposure comprises a contact exposure. A strip of film can be placed in contact with a partially pre-exposed master on a cylindrical drum in a light tight housing so that pre-exposed section of the film can be exposed by one activation of an electronic flash located in the center of the drum.

Abstract: A camera has a wide-angle taking lens and a telephoto taking lens for forming simultaneous wide-angle and telephoto images of the same subject, to make wide-angle and telephoto simultaneous exposures on a single frame of film. A wide-angle/telephoto selection indicator is supported for movement between the taking lenses and the frame of film to prevent either the wide-angle or telephoto image from being fully exposed on the frame of film. Thus, one of the simultaneous exposures is provided with an indication that it is not to be printed as a picture.

Abstract: A multiple lens image pickup apparatus includes a plurality of image pickup systems, a control system, and an optical viewfinder. Each image pickup system is arranged to allow an angle an optical path makes through the system to be changed. The control system selects a stereoscopic photographing mode in which images taken through the plurality of image pickup systems overlap in a large proportion, or a panoramic photographing mode in which images taken through the plurality of image pickup systems overlap in a small proportion. The optical viewfinder selectively sets an observing range in accordance with the photographing mode selected.

Abstract: An eye imagining apparatus where, in the case of a stereoscopic image, a beam from a left stop of a stereoscope stop and a beam from a right stop of the stereoscopic stop form an eye fundus image on a surface of a cylindrical lens array. These beams also reach adjacent image pickup device elements of an image pickup device of an image pickup unit, respectively. With the cylindrical lens array having the pitch width corresponding to two image pickup device elements, the focal length is determined so that an image of the stereoscope stop is focused in the pitch width, and the imaging plane of the cylindrical lens array is focused on the image pickup device by relay lens apparatus. On the other hand, with a monocular image, a single stop plate is put in the optical path instead of the stereoscope stop and the cylindrical lens array is retracted from the optical path, whereby the image is photographed with a higher horizontal image definition.

Abstract: A camera back for sequentially exposing two spatially separate images on regular or self-developing film adapted for a variety of single lens cameras. The camera back includes an adapter plate disposed between the camera and a film back wherein a dark slide is movable by the force of gravity between two positions in the adapter plate, by rotating the adapter plate 180 degrees, thereby blocking a lower half of the film from the exposing radiation. The dark slide is moved exclusively by its own weight, thereby making complicated levers and light-tight feedthroughs unnecessary.
