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： A photographic copying machine has a copying unit which must receive a web of unexposed photosensitive web material well above the floor level. The web material is confined in cassettes which must be lifted before they reach a level in which the web material which is confined therein can be drawn into the copying unit. In order to facilitate manual manipulation of a relatively heavy and bulky cassette, the latter is provided with handless and with one part of a separable coupling which constitutes a hinge and enables the person in charge to pivot the cassette to an upright position subsequent to manual lifting approximately to the chest level. If necessary, the pivoted cassette is thereupon pushed into a chamber of the copying unit. A cassette for reception and storage of freshly exposed photosensitive web material can be manipulated in the same way.

摘要： A strip of originals is copied onto a band of copy material at high speed using a highly automated copier which measures the densities of the originals in the primary colors and calculates exposures from the densities. The calculated exposures for each original in each primary color are recorded. The band of exposed copy material is developed and the copies are evaluated. Unsatisfactory copies are marked. The band of copy material is subsequently cut into individual copies and the unsatisfactory copies, as well as the corresponding originals, are collected. These originals are recopied in a second copier which is far less sophisticated and expensive than the first copier. The exposures used to recopy an original are derived by applying correction factors to the recorded exposures for the original. By performing the recopying procedures, which are rather slow because they require manual operations, in a second copier, the output of the high speed copier can be maintained.

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： 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： 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 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： 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.
