    • Compact dual focal length cameras are disclosed having wide angle and telephoto modes of operation. The ratio of telephoto to wide angle ratios is at least 3 to 1, but is typically higher so that the cameras can be used in conjunction with binoculars to take telephoto pictures that give the same visual appearance as when the same scenes are observed through binoculars. Compactness and increased focal length are achieved via four mirror arrangements one preferred embodiment of which wraps around the camera film plane and uses a single constant angular velocity shutter for providing both wide angle and telephoto exposure times. Compact, single-use, medium telephoto cameras are also disclosed.
    • 公开了具有广角和长焦操作模式的紧凑型双焦距照相机。 长焦比与广角比的比例至少为3比1,但通常较高,因此相机可以与双筒望远镜结合使用,以获得与通过双筒望远镜观察相同场景时相同的视觉外观的长焦照片。 通过四个镜子布置实现了紧凑性和增加的焦距,其中一个优选实施例围绕相机胶片平面并且使用单个恒定角速度快门来提供广角和远摄曝光时间。 还公开了紧凑型一次性中长焦照相机。

    • Photographic film including a flexible substrate sheet divided on one side into a multiplicity of different picture areas provided with respective layers of photosensitive chemical material having a plurality of different photosensitivities. Thus, each sheet or strip of film is essentially multiple ASA film. Such a film strip is provided with detectible code on a substrate sheet for encoding the photosensitivities of the different picture areas in a readable format. A camera utilizing the film is provided with a magnetic reader for determining film speeds or photosensitivities of the different picture areas on the film. A film transport mechanism is controlled by a microprocessor to move an unexposed picture area of an appropriate ASA to an exposure zone of the camera, either in response to a manually selected ASA or an automatic determination of optimal film speed in accordance with lighting conditions as detected by a light sensor, subject distance, etc. The microprocessor includes a memory for storing in encoded form which picture areas of the film have been exposed.
    • 照相胶片包括柔性基材片,其一侧分成多个不同的图像区域,该图像区域设置有具有多个不同感光度的感光化学材料的各个层。 因此,每片薄膜或薄膜基本上是多个ASA薄膜。 这样的胶片条在基板上设置有可检测的代码,用于以可读格式对不同图像区域的光敏度进行编码。 使用该胶片的相机设置有用于确定胶卷上不同图像区域的胶片速度或光敏度的磁性读取器。 胶片传送机构由微处理器控制,以将相应的ASA的未曝光图像区域移动到照相机的曝光区域,或者响应于手动选择的ASA或根据检测到的照明条件自动确定最佳胶片速度 通过光传感器,被摄体距离等。微处理器包括存储器,用于以胶片的图像区域曝光的编码形式存储。

    • A lighting device for a card simultaneous photographing camera which is easy to operate and which permits miniaturization includes a pair of lenses, with a first lens 2 for person photographing and a second lens 3 for card photographing mounted in a row on the front of the card simultaneous photographing camera 1, a semitransparent reflector plate 18 installed so that it may move back obliquely from the top edge of a nearly box-shaped casing fixed or installed through a frame change-over mechanism corresponding to both lenses, and extend up to the front of a flash window 12 of strobe flash device 10, a lens hood 21 corresponding to the lens 2 for person photographing, a card holding frame 23 for holding the card exchangeably corresponding to the lens 3 for card photographing, and a light diffusion box 25 provided between the reflection side of the semitransparent reflector plate 18 and the card holder. This lighting device serves to separate the light fluxes emitted from strobe flash device 10 into a forward transmitted light flux component and a downward reflected light flux component and apply the flux components simultaneously on the two subjects.
