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： 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： A method, and an apparatus for carrying out the method, for purifying exhaust gases from internal combustion engines is provided. The engines having a catalyzer system which includes a first catalyzer and at least one second catalyzer, arranged downstream of the first catalyzer, for the conversion of HC, CO and NO.sub.x exhaust gas constituents. Exhaust gases flow through both catalyzers during the entire operating period of the engine. The first catalyzer is suitable for at least the catalytic conversion of HC and CO exhaust gas constituents. In a first step of the method, the first catalyzer is operated over-stoichiometrically during the cold starting phase in order to reduce the HC and CO emissions and, in a second step of the method with .lambda.-controlled stoichiometric exhaust gas composition, the catalytic conversion of the exhaust gas in the first catalyzer is at least largely de-activated and takes place in the second catalyzer. Substantially better endurance of the first catalyzer is attained for the same good reduction in the exhaust gas pollutants.

摘要： An exhaust-gas filter, for example a soot-particle filter, has a filter element which has inlet passages for the raw gas and outlet passages for the clean gas. In order as far as possible to prevent clogging of the filter over the running time caused by deposits on the filter walls, the raw-gas passages are configured with a larger cross-section than the clean-gas passages.

摘要： A method for electronic reduction of the contrast of video images as early as during recording provides electronic brightening of the shaded zones of a video image in a camera as early as during recording while maintaining the detail contrast even in the brightened regions. A blurred diffuse image of the motif is produced on the image sensor in the camera by the objective and the electronically alterable diffusion element, and is stored in a frame store. The black and white contrast of the mask is determined in the evaluation circuit, and a control variable is generated pixel-by-pixel from this. The focused video image which is subsequently produced on the image sensor when the diffusion element is switch to be crystal-clear is read and is amplified or attenuated pixel-by-pixel such that the shadowed parts are brightened and/or the bright zones are attenuated.

摘要： An exposure of a color film is scanned at a multiplicity of points in each of the primary colors. The color compositions of the points are evaluated to identify color compositions characteristic of skin tones, and a color space is created based on these color compositions. Scanned points whose color compositions lie in the color space undergo an examination to ascertain whether or not they actually represent skin. The examination is concerned primarily with the positions of such scanned points within the exposure and secondarily with density differences between the points and specified zones of the exposure, density differences between adjacent points, and the nature of any groups formed by the points, only those scanned points which actually represent skin are considered when calculating the amount of copy light for the exposure in each primary color.

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： The strip of originals to be copied is transported, prior to copying, through an evaluation station. There, the originals are evaluated with respect to density, color, copiability, or the like. A discrete strip-shaped information carrier is connected to the strip of originals and runs along the length of the strip of originals. The connection is effected either upstream of the evaluation station or at the evaluation station. Information derived from the evaluations performed at the evaluation station is entered upon the information carrier alongside the associated ones of the originals.
