摘要： A color television video signal is directly read out in synchronism to the scanning speed of a scanner, the video signal thus read out is converted into three primary color signals, and these three primary color signals are in turn converted into process video signals, which are supplied to the scanner. A printing plate can be produced directly from a television video signal without requiring any color picture original.

摘要翻译： 与扫描仪的扫描速度同步地直接读出彩色电视视频信号，由此读出的视频信号被转换为三原色信号，这三个原色信号又被转换为处理视频信号， 提供给扫描仪。 可以直接从电视视频信号产生印版，而不需要原始的彩色图像。

摘要： A photography apparatus for television picture comprises a video tape recorder which detects a frame specifying signal recorded on an audio track corresponding to a frame image next to a predetermined frame image by a detecting head disposed before the audio head by a distance corresponding to one field in the direction of tape travel; a memory device for storing one frame image produced by the video tape recorder when the video tape recorder detects the frame specifying signal; an NTSC decoder for separating the signal stored in the memory into three primary color signals; a monochrome monitor for reproducing images corresponding to each of the three primary color signals produced by the NTSC decoder; and a camera with a vertically elongated aperture diaphragm for forming, on color film, multi-exposed images on the monochrome monitor through color filters passing only the respective primary color corresponding to each image.

摘要： A method and apparatus for obtaining an accurate half-tone dot percent of each color separation where a color designated by a color specimen is to be reproduced by printing of ink of the colors, for example, yellow, magenta, cyan and black. A variety of color charts printed using predetermined combinations of half-tone dot percents are optically measured to obtain color information of the colors printed on the color charts. The obtained color information values together with the corresponding predetermined combinations of half-tone dot percents therefor are then utilized to prepare a conversion table of color information and corresponding half-tone dot percents for reproducing each of the colors printed on the color charts. A color specimen is then optically measured to detect color information of a color to be reproduced. The color information obtained from the color specimen is then successively compared with the color information of the conversion table, and the color information of the conversion table is selected which most closely corresponds to the color information obtained from the color specimen. The combination of half-tone dot percents corresponding to the selected color information from the conversion table is then displayed or otherwise outputted. The outputted combination of half-tone dot percents may then be used to reproduce the color designated by the color specimen. The method and apparatus also provides for interpolation operations if the color information obtained from the specimen does not precisely correspond to the color information in the conversion table. Further, the method and apparatus also provides for generating an expanded conversion table having expanded combinations of half-tone dot percents and corresponding expanded color information, and for performing an interpolation operation if a value of 0% and/or 100% is included in the combination of half-tone dot percents corresponding to the selected color information so as to obtain an interpolated combination of half-tone dot percents corresponding more closely to the color information obtained from the color specimen.
