    • In a first embodiment of the invention, a transparent plate is mounted at the film lane within a camera. The transparent plate includes a translucent diffusion pattern which diffuses incoming light rays reflected from the subject and effectively repositions them in a controlled manner prior to the light exposing the film. Proposed diffusion patterns may alter the light rays to create characteristics indicative of various types of paintings or may produce a controlled grainy appearance to an image recorded on film. In another embodiment of the invention, the transparent plate is mounted in a film cartridge. In another embodiment of the invention, a length of plastic film (a pattern strip) is positioned adjacent to a similar length of photographic film (film strip). An appropriate translucent diffusion pattern is provided onto one surface of the pattern strip, along its entire length. Both strips are rolled into a conventional 35 mm film canister and dispensed simultaneously, as needed (within the camera) so that each frame of film has a separate mask in front of it, at the film gate of the camera. In another embodiment of the invention, a transparent plate having a translucent diffusion pattern is positioned between the main lens of the camera, and the camera body. In this arrangement, a correcting lens is required to bring the pattern of the particular pattern into sharp focus with the image at the film plane to be exposed on film.
    • 在本发明的第一实施例中,透明板安装在相机内的胶片通道上。 透明板包括半透明扩散图案,其漫射从被摄体反射的入射光线并且在曝光该膜之前以受控的方式有效地重新定位它们。 建议的扩散图案可以改变光线以产生指示各种类型的绘画的特征,或者可以对记录在胶片上的图像产生受控的粒状外观。 在本发明的另一个实施例中,透明板安装在暗盒中。 在本发明的另一个实施例中,一段长度的塑料膜(图案条)被定位成与相似长度的照相胶片(胶片条)相邻。 沿图案条的整个长度,在图案条的一个表面上提供适当的半透明扩散图案。 根据需要(两个相机内),将两个条卷成传统的35毫米胶片盒,同时进行分配,以使胶片的每个胶片在相机的胶片门处具有独立的掩模。 在本发明的另一个实施例中,具有半透明漫射图案的透明板位于照相机的主透镜和照相机主体之间。 在这种布置中,需要使用校正透镜来使特定图案的图案与胶片平面上的图像一起形成锐焦,以便在胶片上曝光。

    • A camera for partially preexposed, multiple exposure film including a body with an exposure well and a film track across the well. A lens is attached to the camera body at the other end of the exposure well. A mask which includes a plate and a substantially perpendicular flange is positioned at the back of the exposure well adjacent to the film track. The flange extends into the exposure well and is adhered to the wall thereof. The plate includes margins to overlap with the body of the camera about three sides around the exposure well. Another camera includes an asymmetrically arranged exposure well relative to the film track such that the body of the camera about the exposure well extends to cover the preexposed image segment on a multiple exposure film strip.
    • 一种用于部分预曝光的多曝光胶片的照相机,其包括具有曝光良好的主体和穿过该井的胶片轨道。 透镜在曝光孔的另一端连接到照相机主体。 包括板和基本上垂直的凸缘的掩模位于曝光井的与胶片轨道相邻的后部。 凸缘延伸到暴露孔中并粘附到其壁上。 该板包括与照相机主体重叠的边缘围绕曝光井的三个侧面。 另一相机包括相对于胶片轨道的不对称布置的曝光井,使得照相机周围的曝光孔的主体延伸以覆盖多个曝光胶片条上的预曝光图像片段。

    • A camera is capable of forming different photographic image plane frames by causing a light blocking member which is movable in at least a photographic optical path to block part of a photographic light flux. The camera is provided with an urging member for imparting an urging force to the light blocking member, the direction of the urging force being changed when the light block member is located at a particular position in its movement course, a switching member arranged to switch its state at a point in a process in which the light blocking member moves from its maximum retracted position where the smallest amount of light flux is blocked to the particular position, and a display member for visually displaying the state of movement of the light blocking member, i.e., which of the photographic image plane frames has been formed, in accordance with the state of the switching member. In the above arrangement, during a photographic image plane frame switching operation, even if the light blocking member stops at or near the particular position and an imperfect photographic image plane frame is formed, a photographer can be informed that the photographic image plane frame as formed at least does not correspond to a photographic image plane frame state obtainable when the light blocking member is located at the maximum retracted position.
    • 相机能够通过使至少可以在照相光路中移动的阻光元件阻挡照相光通量的一部分来形成不同的摄影图像平面框架。 照相机设置有用于向遮光构件施加推动力的推动构件,当光阻挡构件位于其移动路线中的特定位置时,推动力的方向改变;切换构件,其布置成将其切换 在遮光构件从其最小光通量被阻挡到其特定位置的最大缩回位置移动的过程中的一个点处,以及用于可视地显示遮光构件的移动状态的显示构件, 即,根据切换构件的状态已经形成摄影图像平面框架中的哪一个。 在上述布置中,在摄影图像平面框架切换操作期间,即使遮光构件停留在特定位置处或附近,并且形成不完美的摄影图像平面框架,摄影者可以被通知摄影图像平面框架形成 至少不对应于当遮光构件位于最大缩回位置时可获得的摄影图像平面框架状态。
