    摘要: What is proposed is a method for the color correction of digital image data generated by spectral absorption of white light in color filters of a first representation means. Color film material, in particular, is taken into consideration as the first representation means. For this purpose, firstly the primary color values R, G, B of the image data on the color film are detected. Said primary color values R, G, B are corrected in order to generate secondary color values R′, G′, B′ which are related to a second representation means, for example a monitor. This correction involves taking account of the absorption of light in secondary densities of the colorants of the film material which form the color filters of the first representation means. For this purpose, a plurality of absorption spectra are generated for different densities of the colorants. Finally, the spectral profile of the absorption spectra of the colorants influences the correction of the primary color values for generating the secondary color values. This follows the aim of achieving a maximum correspondence between the color representation with the first representation means and the color representation with the second representation means.

    摘要: System for the sequential illumination of an imager comprising a color wheel comprising at least two coplanar subsets of three colored segments The color wheel comprises at least one subset of segments of primary colors 61R, 61G and 61B, and one subset of segments of composite colors. The subset of segments of composite colors comprises a segment transmitting in the ranges of wavelengths corresponding to red and to green, a segment transmitting in the ranges of wavelengths corresponding to green and to blue, and a segment transmitting in the ranges of wavelengths corresponding to red and to blue. Thus, the luminosity of image display systems is improved, and the phenomenon of “color break-up” is appreciably reduced. Corresponding projection appliance.

    摘要: A high performance single light valve color projection system that enables sequential display of color, and an addressing process for this system. Several rotating glass plates are sequentially inserted between the light valve and the objective. These glass plates create a spatial offset of the image of light valve pixels three times per frame on the projection screen. The sets of plates are rotated by a motor with an axis parallel to the optical axis of the motor, and intersect the image beam at each image frame.

    摘要: The invention proposes a short-distance front projection system, that is to say with a wide angle, occupying a small volume and offering a possibility of focusing as well a zoom function. It makes it possible to obtain images with a diagonal greater than 2 meters, the whole of the optical system being at least 50 cm from the plane of the image. This projector is constructed on the basis of three optical elements: an ocular, an afocal lens system and a final group forming an objective intended to form the intermediate image in front of the mirror.
