Abstract: Apparatus for imaging photographic negatives onto light-sensitive photoprint material includes a platform (3) for the print material; a digital image projection system (2) with an electronic image generation unit; and an integrated analog image projection system (1) with an light source and a negative holder. The image generator of the digital image projection system is disposed outside the light ray path of the analog image projection system. The projection systems are so constructed and arranged that the photoprint material on the platform (3) can receive images from both projection systems simultaneously or consecutively. When a change is made for the projection of images by one projection system to the other, the two light ray paths remain unchanged.

Abstract: There is disclosed a method for determining the amounts of individual copying light when copying color originals, particularly color negatives which are combined into films. The color originals are scanned photoelectrically and separately in the primary colors by region or by point, and the results of the measurement are used to control the amounts of copying light. For each scanned region a first difference is formed between the density values of two basic colors, a second difference is formed between the density values of one of these basic colors and the third basic color, and the average density is formed from the density measurements of the three basic colors. In each case, a functional relationship with the average density is produced, known as a color density difference curve, which describes the color behavior of the recording material on which the copy is to be made. This functional relationship supplies film-specific values for producing copies of the film, the film-specific values being used for the determination of the amounts of copying light for the original to be copied. For films of one type, the functional relationship between color density difference values and average densities describing the color behavior common to this are determined and stored as standard color density difference curves. When a film of this type appears, these stored standard color density difference curves are used to determine copying light quantities.

Abstract: 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.

Abstract: An apparatus and method for handling photographic film within the print-exposure section of a photographic printer. A mask matches the film frame (negative) and has a window for the passage of the exposure light. The mask also has holes through which air can be directed onto the film. A guide for the edges of the film parallels, and demarcates a gap with the mask. A source of air under either overpressure or underpressure supplies such air to the mask (4) and the film (1) through the air-direction openings (15). The air is supplied with overpressure while the film is being advanced. The air is supplied with underpressure while the print is being exposed to clamp the film.

Abstract: 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.

Abstract: 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.

Abstract: Apparatus for convoluting exposed and copied photographic films on the cores of takeup reels has an advancing mechanism which transports successive films along a given path so that the leaders of successive films can be engaged by the gripper of a pivotable arm serving to transfer the leader of the film in the path toward the peripheral surface of the core of an empty takeup reel. The reel has no flanges or is provided with a single flange carrying or adjacent a fixedly mounted or movable protuberance which defines with the peripheral surface of the core a gap for the leader of the film. Once the leader has entered the gap and the takeup reel is set in rotary motion, the film is wound onto the protuberance and is thus affixed to the core. The length of the protuberance is less than the axial length of the core but exceeds one-fourth of such axial length.

Abstract: A photographic copying machine wherein the images of successive frames on a long roll of spliced-together exposed and developed customer films are copied while successive films are advanced stepwise from a supply reel on a first driven mandrel toward and is convoluted on a takeup reel on a second driven mandrel. The copying machine employs a third mandrel which can support a fresh roll in the plane of the roll on the first mandrel, and a fourth mandrel which can support an empty takeup reel in the plane of the rotating takeup reel. The leader of the fresh roll is located adjacent the film path ahead of the copying station and is automatically advanced into the range of an automatic attaching mechanism when the trailing end of the expiring roll has advanced beyond the copying station. The attaching mechanism secures the leader of the fresh roll to the core of the empty takeup reel, and the machine is then ready to make copies of frames forming part of the fresh roll. The filled takeup reel on the second mandrel is replaced with an empty takeup reel and a fresh roll is placed onto the first mandrel while the machine copies the frames of the roll which is supported by the third mandrel and is convoluted on the takeup reel on the fourth mandrel.

Abstract: An exposed and developed strip of film has a series of frames which are to be copied. The strip is scanned at a multiplicity of regions to measure the transparencies in the three primary colors, and the most transparent region of the film strip is established. The neutral density of each region of a frame is calculated as are the density differences between the respective region and the most transparent region in the three primary colors. The color density differences for each region are plotted on a color density diagram having six equally spaced axes which radiate from a common origin. The origin is defined by the color densities of the most transparent region while the respective axes represent the three primary colors and the three complementary colors. The color density diagram is divided into four color segments. The density differences for each region are vectorially added in the color density diagram to generate a resultant vector. The length of the resultant vector is compared with a reference value which is a function of the color segment into which the vector projects and is also a function of the difference in neutral density between the region under investigation and the most transparent region. If the length of the resultant vector is greater than the reference value, a color dominant is assumed to be present.
