摘要： An exposed and developed filmstrip and band of similar length are connected edge-to-edge. An address for each negative of the filmstrip is imprinted on the band in the form of a bar code adjacent to the respective negative. The negatives are scanned and exposure values are calculated for the negatives from the resulting data. The exposure values are used to make proofs, and the exposure values for each negative are then stored in a memory under the corresponding address. When an order for final copies of a particular negative is subsequently received, the address of the negative is read from the band and used to retrieve the respective exposure values from the memory. The final copies are thereupon made based upon the retrieved exposure values.

摘要： A film has a series of exposed and developed negatives. Each negative is scanned at a multiplicity of regions, and the densities of each region in the three primary colors are measured. A blue/red density differential is derived for each region by subtracting the red density of a respective region from its blue density. The neutral density of each region is calculated, and every region is assigned a coordinate on a plot of blue/red density differential versus neutral density. According to one embodiment, the blue/red density differential for each region having a neutral density equal to or greater than a limiting value is then subtracted from the blue/red density differential given by a characteristic curve for the film. The differences obtained in this manner are analyzed, at least for selected negatives, and the minimum difference for each selected negative is determined. The region corresponding to the minimum difference is that region of a negative having the maximum blue density. The blue/red density differential for the region of maximum blue density is compared with a pair of reference values derived from respective reference curves representing blue/red density differential as a function of neutral density. Based on the results of this comparison, each selected negative is classified as to whether it was exposed by artificial light or natural light, and is assigned an appropriate color correction factor for copying. Another embodiment is employed if the characteristic curve is found to lie near one of the reference curves. Here, the steps of subtracting blue/red density differentials and analyzing the resulting differences are omitted, and all negatives of the film are immediately classified as having been exposed by artificial light.
摘要翻译：一部电影有一系列暴露和发展的负面影片。每个负数在多个区域被扫描，并且测量三原色中每个区域的密度。通过从其蓝色密度减去相应区域的红色密度，为每个区域导出蓝色/红色浓度差异。计算每个区域的中性密度，并且在蓝色/红色密度差异与中性密度的图上分配每个区域的坐标。根据一个实施例，然后从具有等于或大于极限值的中性密度的每个区域的蓝/红密度差被从由薄膜的特性曲线给出的蓝/红密度差减去。分析以这种方式获得的差异，至少对于所选择的否定，并确定每个所选阴性的最小差异。对应于最小差的区域是具有最大蓝色密度的负区域。将最大蓝色密度区域的蓝色/红色浓度差异与从表示蓝色/红色密度差异的各个参考曲线导出的一对参考值作为中性密度的函数进行比较。基于该比较的结果，每个选择的阴性被分类为是否被人造光或自然光曝光，并且被赋予适当的颜色校正因子进行复制。如果发现特征曲线位于一个参考曲线附近，则采用另一个实施例。这里，省略减去蓝色/红色浓度差异并分析所得差异的步骤，并且将膜的所有负片立即分类为已经通过人造光曝光。

摘要： Successive frames of a web of photographic color film are subjected to objective examination during transport through an automatic evaluating circuit which may constitute a discrete prereader or a prereader which is integrated into a copying machine upstream of the copying station. The prereader furnishes signals which represent color and/or density correction data for reproduction of those film frames which can be properly copied only with a setting of exposure controls which deviates from the average setting for copying of the majority of film frames. The objective examination of all film frames is followed by a subjective examination which is performed by an attendant who inspects at least some of those film frames whose examination by the prereader resulted in the generation of correction signals. The attendant inspects the film frames at the copying station or at a second station which is located immediately downstream of a discrete prereader, and the attendant simultaneously observes the corresponding correction signals which are furnished by the evaluating circuit and are displayed close to the copying station or in register with film frames at the second station. The attendant can approve, modify or cancel the correction signals, and can also initiate the generation of additional signals, e.g., to identify those film frames which are unfit for copying.

摘要： An automatic prereader for exposed and developed frames of a web of spliced-together photographic color films is preceded by a first station and followed by a second station at the first of which groups of successive frames are subjected to a first subjective examination by an attendant and at the second of which some of the frames are subjected to renewed subjective examination by the same attendant. The attendant actuates one or more pushbuttons upon examination of frames at the first station to produce signals which denote improperly oriented frames, frames which were exposed in artificial light and/or frames which are unfit for copying. Such signals are used to modify signals which are furnished by the automatic prereader. The modified and unmodified signals which are furnished by the prereader are examined for intensity, and those signals whose intensity is outside of a preselected range are displayed at the second station so that the attendant can observe such signals simultaneously with observation of the respective film frames and is in a position to initiate the generation of additional signals which are used to modify or erase the corresponding signals from the prereader before the signals are transmitted to the exposure controls of a copying machine.

摘要： Each original in a strip of such originals is scanned during longitudinal travel of the strip using a scanning spot which repeatedly traverses a stationary scan line extending transverse to the direction of strip travel. The scanning spot has a scanning speed such that the scanning spot travels from one to the other end of the stationary scan line in a time less than the time in which the strip travels a distance equal to the breadth of the scan line. The scanning spot which repeatedly traverses the scan line is generated using a light shield having a slit which delimits the scan line and a rotating disk having equiangularly spaced apertures which move through a stationary light beam passing through the moving strip of originals.

摘要： A photographic copier has a first platform for supporting an original to be copied, and a second platform for supporting copy paper. A focusing system is disposed between the platforms and includes a plate which can be mounted at different distances from the platforms. The plate has a central opening which removably receives a tubular holder. The holder is supported in the opening by a ring which permits the position of the holder relative to the plate to be adjusted. Two lenses are removably mounted in the holder and serve to project an image of the original onto the copy paper. Different magnifications can be achieved in that the copier comes equipped with a variety of holders having different lengths, and a few selected lenses having different optical characteristics. The magnification is changed by simply interchanging holders and/or lenses, and adjusting the position of a holder to be used relative to the plate.

摘要： Film frames are scanned preparatory to copying and a set of density values is generated for each frame. When a frame exhibits excessive contrast, a mask is calculated using the respective set of density values. The calculated mask is formed on an LCD or LED matrix which is in register with the frame. An image of the masked frame is then projected onto copy paper by a zoom objective. The mask has a size which is a function of the magnification factor and/or the mask-to-frame distance.

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： A method of copying a colored original involves measuring the transparency of localized regions of the original in each of the three primary colors. Three localized transparency ratios for each region are formed from the transparency values for the different colors. Three corresponding average transparency ratios for the original as a whole are computed from the localized transparency ratios. Each average transparency ratio is compared with a statistical average of similar ratios obtained from a large number of average originals. If an average transparency ratio of the original to be copied deviates from the corresponding statistical average by more than a predetermined amount, the number of each of the localized transparency ratios lying inside and outside of a predetermined range about the corresponding average transparency ratio of the original is counted. When the number outside of a predetermined range exceeds the number inside, a color dominant is assumed to be present in the original. Otherwise, a color tinge is assumed to be present. The original is copied using a correction factor which depends upon whether a color dominant or a color tinge is present. An alternative method summing the differences between the localized transparency ratios and the respective average transparency ratios of the original is also presented.
摘要翻译：复制彩色原稿的方法包括测量原始图像在三种原色中的每一种中的局部区域的透明度。从不同颜色的透明度值形成每个区域的三个局部透明度比。根据局部透明度比率计算原始整体的三个相应的平均透明度比。将每个平均透明度比率与从大量平均原件获得的类似比率的统计平均值进行比较。如果要复制的原件的平均透明度比偏离相应的统计平均值超过预定量，则每个局部透明度比例在相对于原始图像的对应的平均透明度比的预定范围内和之外的数量算了当超过预定范围的数量超过内部数量时，假定原色中存在着色显性。否则，假定存在颜色色调。使用校正因子来复制原件，该校正因子取决于是否存在着色或颜色色调。还提出了一种将局部透明度比率和原始平均透明度比的差异相加的替代方法。
