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 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： A scanner has a light sensing unit, and a reflecting unit which reflects light to the sensing unit either directly or indirectly. The reflecting unit receives light from an object being scanned or from a light source. In the former case, the light is reflected to the sensing unit directly. In the latter case, the light is reflected to the sensing unit indirectly. Thus, the reflecting unit directs light to an object being scanned and the object transmits or reflects the light to the sensing unit. The reflecting unit is made up of a series of micromirrors, and each of the micromirrors corresponds to a respective point of the object being scanned. The micromirrors are independently movable between rest positions in which they reflect light away from the sensing unit and active positions in which they reflect light towards the sensing unit. The micromirrors are successively moved from the rest positions to the active positions and back to the rest positions so that only one micromirror at a time directs light to the sensing unit. In this manner, scanning is accomplished point-by-point. The scanner can be used in a photographic copier to measure the densities of film frames and thereby regulate the exposure times during copying.

摘要： An infrared measuring beam is emitted from the camera towards the subject, and reflected back as a tiny light spot projected, by an optics which transversely shifts in dependence upon exposure-objective subject-distance setting, onto one, the other or both of two infrared photodiodes. The signals from the two photodiodes are transmitted in processed form to two output flip-flops through the intermediary of a single, shared signal-processing stage, employing time-division-multiplexed transmission of the two photodiode signals, to assure that the signal processing of the two photodiode output signals be as identical as possible.

摘要： A single operating switch replaces the main switch connecting the diaphragm control means to the battery and the release switch activating the film transport. All camera circuits are directly connected to the battery when the main operating switch is closed. An electronic switch is connected in series with the film transport motor and is closed only upon receipt of a control signal. In a first embodiment the control signal is furnished by a timing circuit after a predetermined time interval following the activation of the main operating switch. In a second embodiment the control signal is furnished by a NAND-gate which has a first input which receives a "1" signal while the diaphragm is being adjusted and a second input which receives a "1" signal while the electronic switch is open. The NAND-gate thus furnishes a "1" signal to the electronic switch causing it to be conductive at all times except when the initial adjustment of the diaphragm takes place.

摘要： Pulses are furnished which each indicate transport of a frame. The pulses are counted on a BCD counter. Selected outputs of the counter are connected to the inputs of coupling stages, each including a JK flip-flop. Each flip-flop changes state for a predetermined count on the counter. When each flip-flop changes state, a corresponding indicator lights up, thereby furnishing an indication to the photographer of how many frames have been transported.

摘要： Diapositives are copied on negative photosensitive paper in an apparatus wherein the positive is electronically scanned, line-by-line, and the thus obtained density signals are electronically inverted prior to influencing the beam of a CRT or laser which is used to reproduce the image of the positive on paper, either line-by-line or point-by-point. The inversion of signals renders it possible to scan the high-transmissivity portions of the positives with a narrow beam, i.e., with a high degree of resolution.

摘要： A color filtering device for a charge-coupled photoelectric converting device including a series of uniformly configured photoelectric converting elements which are sensitized by the filtering arrangement in the order of green, blue, green and red. The filtering arrangement includes a transparent filter carrier supporting a series of green, blue, green, red, blue, green, and so on, filtering elements. The active surface of each blue filtering element is equal to the active surface of the assigned photoelectric converting element. The green and red filtering elements are reduced in size in inverse proportion to the spectral sensitivity of the assigned photoelectric converting element. The resulting spacings between the elements are covered by an opaque masking layer, preferably of chromium.
