摘要： A device for use in connection with an electronically controlled photographic printer is described which singles out from an advancing band of original copies those which are unsuitable for reproduction. The device includes a splice sensor for indicating the end or the beginning of an order, a sensor of individual pictures in each order, and a quality (sharpness) sensor. A resettable counter is connected to the splice sensor and to the picture scanner to produce an output pulse after a predetermined number of pictures or after the beginning or end of the order. The output pulse is applied to a selection logic circuit which has adjustable sensitivity levels. The selection logic circuit is controlled by the quality sensor to produce a "print" or "non-print" output pulse applied to the printer-controlling electronics. The output pulse from the counter is controlled by switching means to adjust the sensitivity level in the selection logic circuit so as to either ignore the signals from the quality sensor or to adjust the selection circuit to a lower sensitivity for responding to the quality signals.

摘要： A copier for making prints from photographic negatives has two copying stations arranged in series. A filmstrip is conveyed through the stations in succession, and each negative of the filmstrip is scanned upstream of the copying stations. The data obtained upon scanning is analyzed to calculate the amounts of copy light for the negatives and to determine whether the respective negatives are to be copied under standard conditions or nonstandard conditions. Masters requiring standard conditions are normally copied in the upstream copying station and pass through the downstream station without being copied. On the other hand, masters requiring nonstandard conditions are transported through the upstream station without being copied and are subsequently copied in the downstream station.

摘要： Groups of several successive film frames of an exposed and developed photographic film are examined seriatim at an inspecting station which is located ahead of an encoding station or immediately ahead of the copying station in a photographic copying machine. An attendant examines the frames of a group at the inspecting station and actuates one or more buttons on a control panel in order to produce signals which are indicative of necessary adjustment of exposure controls for copying of certain frames. The buttons are actuated subsequent to depression of selected connecting knobs which form a row along the group of frames at the inspecting station and whose mutual spacing is less than the length of a frame; this insures that at least one knob is in register with each frame of a group at the inspecting station. The depression of a knob insures that the buttons on the control panel can transmit signals to the corresponding stage of a shift register. The stored signals are advanced through successive stages of the shift register, and the last stage transmits the signals to the encoding mechanism at the encoding station or directly to the exposure controls of the copying machine, always simultaneously with arrival of the corresponding film frame at the encoding or copying station.

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： 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 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。
