Abstract: To derive TV signals in standard TV interlace scanning format upon continuous scanning of motion picture film, line by line, the scanned signals are stored in a memory and the lines of the film frame, as they are being scanned, are assigned individual line addresses which permits read-out, in accordance with standard TV signal standards, from the individual addresses. In a preferred form, alternate lines, as they are being scanned, have their addresses incremented by a number corresponding to half the scanning lines (262 for the NTSC system), so that alternate sequentially scanned lines will be stored in the memory as addresses corresponding to interlaced reproduction.

Abstract: A system for the television scanning of films is proposed in which the film is continuously moved and is scanned without interlacing. The respective signals belonging to a scanned line are read into a frame store at an address characterizing the position of the line within the film frame and are read out once again in accordance with the television standard. In so doing, the respective address is formed either by counting pulses derived from the line and frame frequency of the television standard (coupled operation) or by counting pulses derived from the film speed (uncoupled operation).

Abstract: For the line-by-line optical scanning of a film as it passes at high speed through a scanning region, particularly to obtain television image signals, a light source directs light to a sensor. To reduce friction of the film adjacent the scanning region, two rollers or endless belts support the film at positions on the film outside the film frames. These rollers or belts replace the previously usual stationary film guide shoes adjacent the film gate. Lateral guidance of the film can be provided by rollers.

Abstract: Color T.V. signals are transmitted from a transmitter to a receiver or from a color T.V. camera into a transmitter, or the like, in analog form. The luminance information is transmitted throughout approximately 80% of the horizontal line period. During the major portion of the remainder of each of the horizontal line periods, the color information is transmitted in time-compressed and time-division-multiplexed form.

Abstract: A color television imaging method is proposed, which serves both for the scanning of color films and for the taking of scenes with a color television camera. In this method, several primary color signals are formed with the use of at least two sets of opto-electronic converters wherein a charge proportional to the specific quantity of light is integrated within sequential scanning intervals and wherein the integration for the blue primary color signal is carried out over a greater time period and/or area.

Abstract: A method and a circuit for the additive and multiplicative spurious signal compensation of a video signal are proposed. For additive spurious signal compensation, a signal is derived from the "black level" signal, stored, read-out in synchronism with the video signal to be corrected and the thus formed correction signal is subtracted from the video signal. For multiplicative spurious signal compensation, a signal is derived from the "white level" signal, its reciprocal value is formed, stored, read-out in synchronism with the video signal to be corrected and the thus formed correction signal is multiplied with the video signal. A three channel system for color television signals is disclosed.

Abstract: A color T.V. signal includes first and second color-information signals time-division-multiplexed in alternate horizontal line intervals. The first and second signals are written-in in alternation into a first storage device. Only one of the two signals is written-in into a second storage device. Only the other of the two signals is written-in into a third storage device. The storage devices are then read-out in such a manner as to recreate the simultaneous relationship of the first and second color-information signals. As a result of this procedure, each color-information signal passes through only one storage device.

Abstract: Color balance of a color television picture is corrected during those periods when the luminosity falls within prespecified limits and when simultaneously the chroma-saturation is below a prespecified level. A switch operates to change the time constant of an integrator for derivation of a control signal indicative of when the simultaneous conditions are met. One time constant is used when the simultaneous conditions begin and another when they end, thereby allowing better correction of color stains which do not extend uniformly over the entire picture.

Abstract: A system for regulating the color balance of a television signal by storing hue values only during periods when a predetermined luminosity gradient is present in the picture while, simultaneously, the picture remains below a predetermined color saturation threshold, and by using the stored hue value during subsequent periods to derive a regulating signal for controlling a color corrector.

Abstract: A system for correcting color balance of a color television picture to remove tinges of color caused by unbalance. Control signals for color correction are derived and stored from data available in those periods when luminosity is below a lower limit of about 7% or above an upper limit of about 95% and when chroma-saturation is below a prespecified level, for example 20%.
