    摘要： A strip of exposed and developed color film is transported through a transparency measuring system. The transparency of each frame of the film strip in the three primary colors is measured at a multiplicity of regions. The transparency values are converted to density values which are processed to generate a set of data characteristic of the film strip and indicative of the color compositions of the scanned regions. The characteristic set of data and the density values for the individual regions are used to determine whether or not a respective region contains a color dominant. For each frame, the amounts of copying light in the primary colors are established from the density values of those regions which are free of color dominants and have a neutral gray color composition. The amount of copying light in each of the three primary colors is calculated so that the regions of the original having a neutral gray color composition are copied neutral gray. In order to ensure that the copying material registers the copying light in the same manner as the measuring system registers the transparency measuring light, the measuring light is filtered so as to match the spectral sensitivity of the measuring system in each primary color to the spectral sensitivity of the copying material in the same color.

    摘要： The exposed and developed frames of a color film are copied on the basis of information which is obtained by scanning the density of each frame in primary colors as well as on the basis of information which is obtained by imaging a series of gray filters having different densities onto one or more portions of the film outside of the film frames and scanning the density of the image of each filter. The information which is obtained as a result of such scanning is processed by a computer or an amplifier which controls the quantity of copying light in each of the primary colors, either by selecting the interval of exposure of each frame to light in each of the primary colors by controlling the intensity of light in each of the primary colors (if the exposure times in each of the primary colors are identical). The filters can be imaged prior to exposure of frames to scene light and/or shortly prior to development of the film in a processing laboratory. The difference between the results of scanning of filter images which are exposed prior to exposure of frames to scene light and the results of scanning of filter images exposed immediately or shortly prior to development of the film is indicative of changes in characteristics of the material of a film during the interval which elapses between the making of first and second exposures of filters.

    摘要： A method of determining the amounts of light in the basic colors to which an original is to be exposed during a color copying operation to obtain a copy the colors of which are matched in dependence on the image recorded on the original includes the establishment of color density difference functional correlations from values denoting the results of measurements at a multitude of regions of the film strip which includes the original in question. The correlations can then be used for determining the light amounts for most of the originals. Furthermore, the originals are evaluated for discrimination between daylight and artificial light exposures as well as for recognition of originals including color dominants and, in the latter instance, also for ascertaining whether the color dominant was caused by image-important features. The originals which have been classified as artificial light exposures or as including color dominants are treated as such, and the light amounts used for mating copies therefrom are selected differently from those applied when the originals were classified as daylight exposures or do not include color dominants. The signals attributable to detection of the color dominants may be given higher or lower weight, in dependence on the subject matter which they represent, and certain empirical or threshold values may be used to influence the light amount selecting process.

    摘要： The densities of neighboring unit areas of a color photographic negative are measured in each of the primary colors and the results of measurements are compared with each other to ascertain the dimensions and boundaries of negative portions which exhibit dominant colors. Each such portion is considered in the selection of the amounts of copying light to the extent corresponding to a single unit area. The comparison is carried out by a computer which compares the results of measurements of neighboring unit areas, as considered in and at right angles to the direction of movement of the negative relative to the monitoring elements. A result of measurement is disregarded if it deviates from the result of measurement of a neighboring unit area by less than a preselected reference value which may but need not be different for each primary color.
