Abstract: In a color video signal generating apparatus in which a filter having regions respectively selecting light of different wavelength ranges and a screen having separating lenses are optically interposed between an object to be televised and a single image pickup tube to cause such separating lenses to coact with the filter in dividing an image of the object into color components which are projected onto said tube in such manner that said color components when successively encountered in the line scanning direction can respectively become chrominance signals having a predetermined color subcarrier frequency and being of the same frequency band, there are provided index image forming means to form index images on the image pickup tube which, when successively encountered in the line scanning direction, produce in the tube output frequency or angle modulated index signals having a carrier frequency which bears a predetermined relationship to the color subcarrier frequency and a frequency band which is different than the frequency band of the chrominance signals, and the positions of the respective color components in the chrominance signals are indicated by the index signals to permit the extraction from the tube output of color video signals.

Abstract: In a color video signal generating apparatus in which an image of the object to be televised is projected through a color filter onto the photoelectric conversion layer of an image pickup tube and is divided into color component stripes which are successively scanned so that the respective light intensities of the stripes appear as corresponding successive color component signals in the electrical output of the tube, there are also formed on the photoelectric conversion layer two sets of bright and dark stripes having respective spatial frequencies that are different from each other and also each different from the spatial frequency of the color component stripes on such layer so as to provide respective index signals in the tube output, a beat signal is derived from the tube output with a frequency that is the difference between the frequencies of the respective index signals, and such beat signal, which may be frequency multiplied to correspond to the frequency of the color component signals, is employed as a reference for separating the color component signals from each other in the tube output.

Abstract: In a color video signal generating apparatus in which an image of an object to be reproduced is projected, as stripelike color components thereof, onto the photoconductive layer of a vidicon tube having an electrical output composed of successive signals corresponding to the light intensities successively encountered by the electron beam of the tube in scanning the photoconductive layer, such stripelike components of the image are extended obliquely to the line scanning direction, and the electron beam is deflected from the normal scanning line, preferably by onehalf the pitch between successive scanning lines of a standard raster, for every other scanning line of such raster, so that, when a picture is reproduced from the tube output with the standard raster, periodic noises appearing in the tube output will be randomly distributed in the reproduced picture and hence not readily perceptible.

Further, an arrangement is provided to control the horizontal scanning velocity of the pickup tube.
