摘要： An exposed and developed photographic filmstrip having a series of image areas is conveyed along a path and is photoelectrically scanned at a first location of the path to detect regions characterized by marked density jumps. A signal is generated in response to detection of each such characteristic region and a first distance measuring device disposed near the first location assigns a first distance reading to each characteristic region upon detection thereof. The first distance readings are representative of the positions of the characteristic regions longitudinally of the filmstrip. Each signal is stored together with the respective first distance reading. The stored signals and first distance readings are used to calculate the positions of the image areas longitudinally of the filmstrip, and the calculated positions are likewise stored. From the first location, the filmstrip travels to a second location of the path where a notch is punched in the filmstrip adjacent to each image area. Immediately upstream of the second location, the filmstrip is photoelectrically scanned for a second time to again detect the characteristic regions.

摘要： A filmstrip containing a series of images is conveyed along a path which passes by a copying station and a scanning station. The filmstrip is advanced in steps using transporting rolls and a narrow segment of the filmstrip is scanned at the scanning station after every step. A first set of measurements obtained upon scanning of the filmstrip is used to calculate the amounts of light and the exposure times required to properly reproduce the images. A second set of measurements is used to detect characteristic regions of the filmstrip having abrupt changes in density. The positions of the characteristic regions along the filmstrip are established by a counter which counts the steps undergone by the filmstrip and the measurement or measurements corresponding to each characteristic region are stored together with the respective position. The positions of the characteristic regions and the second set of measurements are used to calculate the positions of the images along the filmstrip. After the filmstrip has been completely scanned, the filmstrip is conveyed along the path once more. During the second trip along the path, the filmstrip is scanned again while the distance traveled by the filmstrip is measured by the counter. Upon detection of a characteristic region, the position of such region along the filmstrip as measured by the counter during the second trip is compared with the stored position obtained during the first trip. If the positions are different, the counter is changed to match the stored position. This compensates for slip between the filmstrip and the transporting rolls thereby allowing the images to be accurately positioned in the copying station for reproduction as the filmstrip travels along the path for the second time.

摘要： Successive frames of an exposed and developed customer film are monitored during transport of the film in a first direction, and the information which is gathered during monitoring of discrete frames as well as of the entire film is stored in the memory of a microprocessor. The direction of travel of the film is then reversed and successive or selected frames of the film are copied during intervals between successive stepwise advances of the film in the second direction. Copying light which is used for the making of reproductions of images of the film frames is also used for illumination of film frames during monitoring. A mirror is provided to reflect light to the monitoring unit during travel of the film in the first direction, and such mirror is retracted preparatory to copying which starts with the last monitored frame and proceeds toward the first monitored frame of the film. The film is converted into a growing roll during monitoring of its frames.

摘要： Strips of coherent, exposed and developed film frames are advanced past, and discrete frames are placed onto, a window at a monitoring station where successive increments of the film frames are monitored by a device having photocells forming at least one row which extends transversely of the path of advancement of strips. The monitoring device is at a standstill during advancement of strips but is transported past a discrete frame at the monitoring station. Such monitoring device can ascertain the density of film frames, and its photocells generate signals which are used to image the frames onto photographic paper.

摘要： A strip of exposed and developed film has a series of exposures and corresponding exposure identification numbers. The strip is conveyed through a scanning station on its way to a printing station. The exposures and identification numbers are scanned in the scanning station to produce output signals indicative of density changes. The signals are processed to generate groups of data which are combined into a data set. Each group includes the position of a respective exposure on the strip, the identification number for the exposure and the position of the identification number on the strip. Film transport is carried out in such a manner that scanning of the strip and processing of the resulting signals are completed before arrival of the strip at the printing station. A control unit uses the data set to position the exposures in the printing station and to print the exposures. The control unit also uses the data set to mark a copy of an exposure with the identification number of the exposure.

摘要： A copier is designed to copy negatives of different sizes onto copying material of different widths. The negatives and copying material are supplied from rolls. The copier includes the following manually controlled components: (i) a set of interchangeable film guides which are used at a scanning station and are slotted to permit photoelectric scanning of the negatives; (ii) a set of interchangeable masks for masking the negatives during copying; (iii) a set of light shafts for illuminating the negatives during copying; and (iv) a movable guide unit for the copying material. A computer associated with the copier is arranged to receive signals indicative of the following manually obtained settings: (a) the type of dimensions of the particular film guide installed in the copier; (b) the type of dimensions of the particular film mask installed in the copier; (c) the type of light shaft installed in the copier or the cross-sectional area of the outlet aperture for the light beam; and (d) the position of the guide unit for the copying material which is related to the width of the latter. The copier further includes a motorized mask for regulating the length of copying material to be exposed, and an adjustable objective having motorized lens elements. The motors for the motorized mask and the lens elements are controlled by the computer. The computer has a memory which stores all possible combinations of settings for the manually controlled and motorized components. When the size of a negative to be copied changes, these components are adjusted for the new size. The manually controlled components are adjusted first. Prior to adjustment of the motorized components, the computer checks the settings of the manually controlled components against the stored combinations of settings to ascertain whether the particular combination of manual settings is possible.

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： Light containing blue, green and red radiation is passed through a colored original which is to be printed on color copy material. The transmitted light is spread out into a color spectrum which extends across a first wavelength range generally corresponding to the blue portion of the spectrum, a second wavelength range generally corresponding to the green portion of the spectrum and a third wavelength range generally corresponding to the red portion of the spectrum. The intensity of the transmitted light is measured throughout the spectrum and average of the resulting raw intensities are taken oer each of a series of wavelength intervals which are much shorter than the first, second and third ranges. The copy material has a gamma value for each wavelength interval and such gamma value represents the spectral sensitivity of the copy material in the corresponding interval. The average intensity for each wavelength interval is multiplied by the respective gamma value to yield a corrected intensity. The corrected intensities for each wavelength range are summed to generate first, second and third sums corresponding to the first, second and third ranges and respectively representing the blue, green and red densities of the original. The first, second and third sums are used to calculate the respective amounts of blue, green and red light required to print the original with a neutral gray density.

摘要： An original to be reproduced is scanned line-by-line, and a scanning signal is generated for each linear, scanned region. The scanning signals represent the densities of the respective regions. A portion of each scanning signal is filtered to remove the higher frequencies. The filtered signal is differentiated to yield first density gradients, and the extreme positive and negative values of the first density gradients are determined for each region. Another portion of each scanning signal is differentiated without first removing the higher frequencies thereby yielding second density gradients. The extreme positive and negative values of the second density gradients are likewise determined for each region. A ratio of the extreme positive second density gradient to the extreme positive first density gradient is formed for each region, as is a ratio of the magnitude of the extreme negative second density gradient to the magnitude of the extreme negative first density gradient. A pair of sharpness values is then established for each region by subtracting 1 from the respective ratios. All of the sharpness values are now grouped according to the second density gradients or, alternatively, according to the second density gradients, as well as the density ranges of the respective scanned regions. The magnitudes of the sharpness values in each group are summed, and the sums compared with respective reference values. The original is classified as to its sharpness depending upon the results of the comparison so that a judgment may be made as to whether the original is worthwhile reproducing.

摘要翻译： 逐行扫描要再现的原稿，并为每个线性扫描区域生成扫描信号。 扫描信号表示各个区域的密度。 每个扫描信号的一部分被滤波以去除更高的频率。 滤波后的信号被分化以产生第一密度梯度，并且确定每个区域的第一密度梯度的极值正值和负值。 每个扫描信号的另一部分被区分，而不首先去除更高的频率，从而产生第二密度梯度。 对于每个区域，同样确定第二密度梯度的极值正值和负值。 对于每个区域形成极端正的第二密度梯度与极端的正的第一密度梯度的比率，以及极端的负的第二密度梯度的幅度与极端负的第一密度梯度的大小的比率。 然后通过从各自的比例中减去1来为每个区域建立一对锐度值。 所有锐度值现在根据第二密度梯度或者根据第二密度梯度以及各扫描区域的密度范围分组。 将每个组中的锐度值的大小相加，并且将总和与相应的参考值进行比较。 根据比较的结果，原件被分类为其清晰度，从而可以判断原件是否值得再现。
