Abstract: An optical comb filter has a plurality of optical comb filter elements disposed successively in the advancing direction of light. The optical comb filter characteristics attenuate and remove specific space frequencies which do not have mutual relationships of odd-number multiples and frequencies of the specific space frequencies. At least one phase plate is interposed between neighboring optical comb filter elements in front and rear positions with respect to the light advancing direction. The phase plate converts a light exiting from the front filter element into a light which is divided in the rear filter element into normal light and abnormal light, exiting with mutually equal light quantity. The normal and abnormal light enters, as incident light, the rear filter element.

Abstract: In a color television camera, a light ray from an object to be taken is split into a plurality of rays to be respectively incident on two or more solid-state imaging devices each equipped with a color separation stripe filter where the imaging devices are positioned so that pixels thereof are horizontally shifted by a predetermined distance from pixels of remaining imaging devices with respect to an image applied thereto. The imaging devices are driven in a sequence, and output signals therefrom are sampled in a sequence so as to produce a single multi-color video signal by combining the plurality of sampled signal components. With this arrangement, the frequency of color signal components within the multi-color video signal is increased from the frequency of each of the output signals from the imaging device. The sampled signal components may be further sampled so that a plurality of color signals corresponding to the colors of the color stripe filters are obtained and their levels are respectively adjusted for obtaining level-adjusted color signal which are then combined to produce a single multi-color video signal.

Abstract: A first set of different color signals represented in a colorimetric system is converted into a second set of different color signals represented in another colorimetric system. Predetermined main parts of the second set of the color signals are determined in response to predetermined first portions of the first set of the color signals. Calculation coefficients are determined in response to the first portions of the first set of the color signals. Predetermined subordinate parts of the second set of the color signals are calculated from predetermined second portions of the first set of the color signals and the calculation coefficients according to an interpolation. The determined main parts of the second set of the color signals and the calculated subordinate parts of the second set of the color signals are combined into a whole of the second set of the color signals. The calculation coefficients are designed so that, if the color signals in the first set vary by equal values, achromatic color data which results from the calculation lies on an achromatic color axis in a color space defined with respect to the readout data of the main parts of the second set of the color signals, and that the sum of squared errors of color conversion is minimized.

Abstract: A frame of photographic film is optoelectronically scanned after development to produce an electronic image which is analayzed to determine the exposure and development conditions of the film. Tone conversion signals are generated in accordance with the analyzed conditions to convert the tone characteristics of the electronic image to optimal values and thereby compensate for non-standard exposure and development. The electronic image of the entire frame, or alternatively only a part of the electronic image corresponding to an unexposed area of the frame, may be used to determine the development conditions.

Abstract: A color television signal generating apparatus comprises a color-resolving striped filter, in a camera tube, for separating the output signal of the camera tube into required signals. Detecting means detects the envelopes of specific positive wave and negative wave signals thus separated. The output of the camera tube is a superimposed signal of a direct wave signal containing signals of three primary colors, of additional mixed colors, and a high-band component signal comprising a group of modulated color signals. This camera output signal results from the amplitude modulation of a carrier wave responsive to filter stripes in the color-resolving striped filter. The carrier wave components have a high harmonic relation relative to two primary color signals. The separating means comprises first separating means for separating the direct signal from the above mentioned superimposed signal and second separating means for separating the high-band component signal. The envelope detecting means comprises a first detector for producing a demodulated output signal in accordance with an envelope resulting from a successive connection of peak values of the positive wave of the thus separated high-band component signal. A second envelope detection means produces a demodulated output signal in accordance with an envelope resulting from a successive connection of peak values of the negative wave of the thus separated high-band component signal.
