摘要： A transparency to be printed is scanned to generate density values which are used to determine the degree of exposure of the transparency. The transparency is further scanned to generate signals representing an image of the transparency. The scanner which is employed for the latter scanning procedure and produces the signals has a linear scanning range and, based on the degree of exposure of the transparency, the illumination intensity or integration time of this scanner is controlled such that the master is scanned within the linear range. The signals generated by the scanner are corrected using a characteristic line selected in dependence upon the degree of exposure of the transparency, the color temperature and/or the film type. The corrected signals are processed to additionally enhance the image of the transparency and are then used to print the image.

摘要： A transparent colored original is scanned region-by-region and the density of each region in each of the primary colors red, green and blue determined. Each region represents an area constituted by a large number of points. The densities for each region are processed to generate parameters characteristic of the coloring of the respective region. These parameters are compared with respective threshold values. An overall density for the original in each of the primary colors is now calculated. In performing these calculations, those regions for which the characteristic color parameters exceed the respective threshold values are assigned less weight than the remaining regions. This is due to the fact that the former regions are assumed to contain color dominants. The orginal is next scanned line-by-line and point-by-point in each of the primary colors to generate imaging signals for use in printing the original on copy material. The magnitudes of the imaging signals are regulated in such a manner that the magnitudes of the signals for the different primary colors have a relationship similar to the overall densities of the original in the primary colors. The imaging signals are electronically processed to enhance the image of the original and the processed imaging signals are then supplied to a printer which reproduces the original line-by-line and point-by-point.

摘要： The gray balance of a color copying apparatus is adjusted by generating three sets of test signals respectively representing red, green and blue components of a test image. The test image is modified by operating on each set of signals with a respective characteristic line. The characteristic lines are stored in look-up-tables constituting part of the apparatus. Each characteristic line has a first point corresponding to a first location of the modified test image and a second point corresponding to a second location of the modified test image. A first copy of the test image is made and the red, green and blue densities of the copy at the first location determined. If any of these densities deviates from a reference value, the corresponding characteristic line is adjusted so that the respective density assumes the reference value. A second copy of the test image is now made and the red, green and blue densities of the copy at the second location determined. In the event that one or more of the densities at the second location deviates from a reference value, the associated characteristic line or lines are further adjusted in such a manner that the first point of each characteristic line remains unchanged.

摘要： A colored original to be reproduced is scanned point-by-point in each of the three primary colors. The resulting imaging signals are processed to generate a luminance signal and a pair of chrominance signals. The luminance signal is branched into a high-pass filter channel and a low-pass filter channel. The high-pass portion of the luminance signal is amplified in accordance with a sublinear characteristic function which causes signals of small amplitude to be amplified to a greater degree than signals of large amplitude. The low-pass portion of the luminance signal is modified per a non-linear characteristic gradation function. The thus-modified high-pass and low-pass portions of the luminance signal are added to yield an enhanced luminance signal. The enhanced luminance signal is divided by the original luminance signal and each of the chrominance signals is multiplied by the resulting quotient. This automatially compensates for the changes in color saturation which accompany changes in brightness. After the multiplication, the chrominance signals are amplified in accordance with a sublinear characteristic function which causes signals of small amplitude to be amplified to a greater degree than signals of large amplitude. This characteristic function further has a form such that no additional ampification takes place beyond a predetermined threshold limit.

摘要： A colored photographic original is scanned at a multiplicity of points in each of the primary colors red, green and blue to generate a set of image signals for each primary color. The average luminance of the original in each primary color is calculated from the radiation used for scanning and respective first correction signals for scattered light arising during scanning are produced from the average luminances. The correction signal for each primary color is subtracted from each image signal of the corresponding set. The corrected image signals are processed to enhance the image carried by the signals. The processed signals are sent to a printer. Furthermore, the processed signals of each set are averaged and the resulting averages used to produce respective second correction signals for scattered light arising during printing. The second correction signal for each primary color is subtracted from each processed signal of the corresponding set. The corrected processed signals are then used to print the image.

摘要： A colored original to be copied is scanned point-by-point in each of the three primary colors red, green and blue. A series of imaging signals is generated for each primary based color on the scanning operation. The signals are subsequently converted into a colored optical image of the original by means of a cathode ray tube which prints the image on color copy material. Prior to conversion, the signals are processed to electronically enhance the image. Following electronic image enhancement, the signals are adjusted to the characteristics of the copy material. The adjusted signals are now modified so as to make them proportional to the illumination intensity of the cathode ray tube or to the logarithm of the illumination intensity. The modified signals are next corrected to adjust the gray balance and/or the contrast of the image. This is accomplished either by multiplying each series of modified signals with a respective correction factor or adding a respective correction factor to each series of modified signals. The signals are thereafter fitted to the characteristic function of the cathode ray tube which then prints the image.

摘要： A colored original is scanned in each of the three primary colors red, green and blue to generate a series of electrical imaging signals for each such color. The signals are electronically processed and then sent to a cathode ray tube having a screen which is coated with a phosphor. The cathode ray tube successively converts the signals of the different series into optical images having the respective primary colors red, green and blue. The images are formed on the screen of the cathode ray tube thereby exciting the phosphor which luminesces to generate printing light. The differently colored images are successively printed on photographic color paper using the printing light emitted by the phosphor as well as respective red, green and blue filters. The phosphor is a rare earth phosphor which emits strongly in the red region of the spectrum and only weakly in the green and blue regions of the spectrum. The weak emissions in the green and blue regions of the spectrum are compensated for by using dichroic green and blue filters having high transmissivities. On the other hand, the strong emission of the phosphor in the red region of the spectrum is balanced by employing copy paper having relatively low sensitivity in this region. Such compensation and balancing make it possible to achieve equal or almost equal exposure times in the different primary colors.

摘要： Upon termination of shooting, the exposure objective of a still or motion-picture camera is automatically returned to a predetermined starting position, such as at the middle of the available range of distance-settings. If the camera's focussing system is fully automatic, this is preferably achieved by overriding normal operation of the focussing system by a command signal indicating that the objective is to be brought to starting position and substituted for the normal-operation command signal generated in dependence upon physically measured camera-to-subject distance. If the normal-operation command signal of the system is manually selected, as in the case of a closed-loop positioning system wherein the command transducer is manually adjusted, or as in the case of an open-loop positioning system in which the actuating signal of the system is manually established, the signal commanding or actuating a return to starting setting is likewise substituted for the normal-operation command or actuating signal.
摘要翻译：在拍摄结束时，静止或动态相机的曝光目标自动地返回到预定的开始位置，例如在距离设置的可用范围的中间。如果摄像机的聚焦系统是全自动的，则优选地通过用指示将目标进入起始位置的指令信号覆盖聚焦系统的正常操作来代替根据物理地产生的正常操作命令信号来实现测量摄像机到拍摄对象的距离。如果手动选择系统的正常操作命令信号，如在手动调整命令换能器的闭环定位系统的情况下，或者在开环定位系统的情况下，其中致动信号手动建立系统的命令或启动返回到开始设置的信号同样代替正常操作命令或启动信号。
