摘要： A projection display system includes: two light sources (102, 105); a condenser (103, 106) for condensing the light from the light sources; a time-division color separating optical system (108) for temporally switching the incident light into a first, second, or third color of light to be emitted; a light valve (118) capable of modulating the incident light individually for each pixel; a lighting optical system (111, 112, 114) for directing the light from the time-division color separating optical system onto the light valve, and a projection optical system (123) for magnifying and projecting a pixel on the light valve. The light from the two light sources (102, 105) is condensed on the time-division color separating optical system or its vicinity by the condenser (103, 106), and then superimposed. This can provide a projection display system that performs time-division driving and can achieve high-brightness projection images without increasing the size and cost of a system.

摘要： Respective light-emitting elements are caused to emit light at the maximum rated outputs and densities of three colors developed by a photosensitive material are made substantially uniform. The maximum rated outputs at light-emitting central wavelengths, of the three-color light-emitting elements are respectively 2.4 mW, 0.04 mW and 1.2 mW. The ratio between the outputs is represented as R:G:B=60:1:30. On the other hand, the ratio between spectral sensitivities of the most-frequently used photosensitive material is represented as R:G:B=1:30:2. An exposure-value ratio on the photosensitive material, which is synthetically obtained from these, reaches R:G:B=2:1:2. Thus, the numerical ratio among the light-emitting elements, for making exposure values uniform becomes R:G:B=1:2:1. The numbers of the respective light-emitting elements are defined so as to reach the least numbers from the numerical ratio (i.e., one R-light-emitting element, two G-light-emitting elements and one B-light-emitting element). Further, a repetition of R-G-B-G, R-G-G-B or the like is most suitable as the sequence of arrangement of the light-emitting elements.

摘要翻译： 使各发光元件以最大额定输出发光，由感光材料显影的三种颜色的密度基本上均匀。 三色发光元件的发光中心波长的最大额定输出分别为2.4mW，0.04mW和1.2mW。 输出之间的比例表示为R：G：B = 60：1：30。 另一方面，最常用的感光材料的光谱灵敏度之比表示为R:G:B = 1:30:2。 从这些合成获得的感光材料上的曝光值比达到R:G:B = 2:1:2。 因此，为了使曝光值均匀，发光元件之间的数值比为R:G:B = 1:2:1。 各个发光元件的数量被定义为从数值比（即，一个R发光元件，两个G发光元件和一个B发光元件）达到最小数量。 此外，R-G-B-G，R-G-G-B等的重复最适合作为发光元件的排列顺序。

摘要： An arrangement of a color enlarger head is disclosed that allows an original picture negative to be irradiated for print-out with an even quantity of light without the need for adjusting a quantity of light transmitted through a diffuse transmission plate disposed on an exit side of a diffusion box. Them is provided below the diffusion box a light distribution adjusting box in which the light rays transmitted through the diffuse transmission plate are appropriately reflected so as to increase the quantity of light entering a peripheral zone of the original picture negative and thereby to equalize the light rays available to print out the original picture negative. Specifically, below The diffuse transmission plate 60 there is provided a light distribution adjusting box 62 defined by a frame 62a and a bottom 62b provided at a central zone with an opening serving as a projecting window 62c. The light rays having entered light distribution adjusting box 62 through a peripheral zone of diffuse transmission plate 60 are reflected not only by the inner surface but also by a lower surface of diffuse transmission plate 60 so that the light rays reflected by the lower surface of diffuse transmission plate 60 at a zone extending around its central zone enter the peripheral zone of original picture negative 66 and then an enlarged lens 42 while the light rays reflected by the lower surface of the diffuse transmission plate at its central zone enter the original picture negative but do not enter enlarging lens 42.

摘要： Spectral filter means in which filter elements have elongated planar surface areas covered with patterns of filtering material. Filter elements are independently movable parallel to their respective surface planes to positions where a given density pattern of filtering material is intersected by a beam of light and filters a given component of the light. Separate filter elements for each of the primary colors and an additional element for dimming all colors are used to control the color and intensity of a beam of light.

摘要： The invention relates to a process and an equipment for making color enlaments in additive method, where the device can be fitted onto the traditional enlargers. By using the solution according to the invention the arrangement of the additive color filters under the lens of the enlarger can be solved in a stable but not containing manner, simultaneously ensuring easy and alternating actuating and integration of the colors of the negative. By means of the comparative process, by using the color-analyzer mask and the properly dark colored reference standards belong to the equipment, the color and density balance of the prints to be enlarged can be adjusted by the way of one single trial development, independent of the individual subjective color perceptional ability.

摘要： A subtractive color printing device for use between a source of white light and a color transparency or negative intended to be exposed to at least a portion of the spectrum of such source. An aperture is disposed in the exposure path between the light source and the negative. A plurality of color filters, each mounted on a separate carrier frame, are positioned for independent adjustment to different positions between one position fully exposing and another position fully spanning the aperture. Each filter carrier is driven to such different positions by a motor. A computer is programmed to power the motors, upon a user input, to drive the filter carriers to preselected positions.

摘要： The additive color system includes a light source providing three component light beams. The component beams are combined to form a composite beam. Three variable-density electrooptical filter units are provided, each arranged in the path of a respective one of the component beams. Each filter unit attenuates the respective component beam in dependence upon a control voltage applied to its control electrodes. A selecting device selects the transmission value to which the filter units are to be set. A circuit generates corresponding control voltages and applies them to the control electrodes of the filter units, and includes compensating circuits for compensating for repeatability errors in the response of the filter units.
