    • The present invention provides an improved backing screen having particular application for use in composite photography. In particular, the present invention relates to color difference composite photography, whether still, motion picture, video, solid state digital electronic or electrophotographic imaging, in which foreground and background scenes are separately recorded and subsequently combined using known "blue screen" or special color background techniques to form a single image. The present invention includes a biaxially stretchable fabric of synthetic fibers treated with a dye formulation, including fluorescence which is reactive to the visible spectrum, to achieve any of a variety of specific spectral loci and luminances, for the purpose of providing a precise chromatic actinic stimulus response for a silver halide photographic film, or similar response for electronic imaging devices. The selected backing is deployed in a support such that the fabric is stretched to a smooth, featureless surface and then illuminated. Foreground subject matter interposed between the camera and the backing or directly on the backing will therefore be readily distinguished and "matted" for compositing by methods well known to the art. In a further aspect of the present invention, the light emitting characteristics of the fluorescent matte fabric of the present invention may be advantageously relied upon to obtain the desired lighting effect in, for example, underwater photography. In yet another embodiment of the present invention, the matte fabric of the present invention may be configured to cover objects or parts of a person in a field of view.
    • 本发明提供了一种改进的背景屏幕,其具有用于复合摄影的特定应用。 特别地,本发明涉及色差复合摄影,无论是静态,运动图像,视频,固态数字电子或电子照相成像,其中分别记录前景和背景场景,并且随后使用已知的“蓝屏”或特殊颜色组合 形成单一图像的背景技术。 本发明包括用染料制剂处理的合成纤维的双轴拉伸织物,其包括对可见光谱具有反应性的荧光,以实现各种特定光谱位点和亮度中的任一种,以提供精确的有色光化刺激 对于卤化银照相胶片的响应或类似的电子成像装置的响应。 所选择的背衬部署在支撑件中,使得织物被拉伸到光滑的,无特征的表面,然后被照亮。 因此,介于相机和背衬之间或直接在背衬上的前景主体因此将容易地被区分并且通过本领域熟知的方法“梳理”以进行合成。 在本发明的另一方面,本发明的荧光消光织物的发光特性可以有利地依赖于在例如水下摄影中获得期望的照明效果。 在本发明的另一个实施例中,本发明的无光纤维织物可以被构造成在视野范围内覆盖人的物体或部分。

    • Apparatus and method is disclosed herein for producing a pair of identical images on the same piece of film except for the appearance of the background which becomes black behind one of the images and clear behind the other. The apparatus includes a background screen reflecting polarized light and a motion picture camera having an image duplicating device carried before the lens thereof comprising a beam split element for optically conducting a pair of images simultaneously through filters via front surface mirrors and prisms to a recording film strip. One filter is of neutral density so that a half frame on the film strip records a black image on a clear background while the other filter is a polarizing filter producing a clear image on a black background on the other half of the film strip frame.
    • 本文公开的装置和方法用于在同一片胶片上产生一对相同的图像,除了在一幅图像之后变成黑色并且在另一幅图像之后清晰的背景的外观。 该装置包括反射偏振光的背景屏幕和具有在其透镜之前承载的图像复制装置的运动图像相机,该图像复制装置包括用于通过前视镜和棱镜通过滤光片同时将一对图像光学地传导到记录膜条带的光束分离元件 。 一个滤光片具有中性密度,使得薄膜条上的半帧在清晰的背景上记录黑色图像,而另一个滤光片是在薄膜条框架的另一半上在黑色背景上产生清晰图像的偏振滤光片。

    • A method for producing a master pattern used for manufacture of a color picture tube phosphor screen is disclosed. An image of an interchangeable shadow mask is formed on the internal surface of the face glass and transferred onto a photosensitive plate, thereby producing a master pattern with a very high accuracy. In the case of a very thin photosensitive plate, the master pattern is produced directly from the interchangeable shadow mask. The method for producing a color picture tube by use of a master pattern involves equipment much lower in cost and easier in manufacturing processes than the conventional methods due to the facts that exposure by flood light is possible and that the shadow mask and the face glass need not be handled as a couple.
    • 公开了一种用于制造彩色显像管荧光屏的母版图形的制造方法。 在面玻璃的内表面上形成可互换的荫罩的图像,并转印到感光板上,从而以高精度产生主图案。 在非常薄的感光板的情况下,主图案直接从可互换的荫罩产生。 通过使用主图案来生产彩色显像管的方法涉及比常规方法低得多的成本和更容易的制造工艺的设备,这是由于可能发生泛光灯暴露的事实,并且荫罩和面玻璃需要 不能像一对夫妇一样处理。
