    An image 1 radiating in at least two different wavelength ranges and/or distributions, e.g. a colour image, is reproduced by means of a lens 2 and an optical splitter 3 simultaneously as two mutually symmetrical images 4, 5 on the photosensitive coating 11 of a photoelectric transducer. The images 4, 5 are converted into video signals 9, 10 by scanning the photosensitive coating 11 by scanning rasters 7, 8 which are substantially mutually symmetrical. This symmetrical arrangement removes the need for devices, for correcting geometrical distortions and variable sensitivities in camera tubes and allows tubes, such as image intensifier tubes, having heavy geometrical distortion to be used. <IMAGE>

    The image of object 1 is displayed through successively located lens 2 and divider 3 images in the form of symmetrical, images on the photosensitive layer 4 of the photoelectric converter 6.
    Lens 2 and divider 3 images distort images, for example, in the form of a pillow.

When reading the potential relief on the photosensitive layer, the received video signal with frequency compaction contains video information of various separations in a checkerboard pattern. From the output of the photoelectric converter 6, the video signal is fed to the coding unit 7, from the output of which through the switch 8 it is fed to the matrix 10, which forms the R, G, B color signals.
    In order to reproduce the achromatic areas of the object 1 without blinking, two filtered images in the form of stripes are formed on the photosensitive layer 4, with each of the two decoded video signals corresponding to a pair of opposite colors.

    The invention relates to television, mainly to an optoelectronic transmission of a color image. The purpose of the invention is to eliminate the glimmer of the image. FIG. 1 shows schematically an apparatus for carrying out the method in FIG. 2-4, the arrangement of both symmetrical images necessary for interrogating rasters of decomposition and reproduction rasters; in fig. 5 is a circuit diagram of an apparatus for carrying out a method of opto-electronic transmission of a color image. The proposed method consists in simultaneously separating the optical color image into two symmetric color images, spectral selection of each symmetric optical color image and their subsequent projection onto the photosensitive layer of the photoelectric converter, converting each symmetric optical color image into a video signal by sequentially reading each of the two separated cc metric color images, encoding of the received video signals from The following reproduction of symmetric color images, wherein reading each of the two divided symmetric optical images is performed by line scan with a scanning offset of one divided symmetric optical color image (Relative to the other divided symmetric optical color image half a line, after encoding the video signal of each of the two separated symmetric optical color images are remembered for half frame time, and during playback used to read the stored video signals simultaneously. A device for carrying out an optical-electronic color image transmission method comprises an object 1, a lens 2, an image divider 3, a photosensitive layer 4, an optical filter 5, a photoelectric converter 6, a coding unit 7 a switch 8, a synchronizer 9 and a matrix TO. The device works as follows. The image of object 1 is displayed through successively located lens 2 and divider 3 images in the form of symmetrical images on the photosensitive layer 4 of the photoelectric converter 6. Lens 2 and divider 3 images distort images, for example, in the form of a pillow. Since the images are located symmetrically about the axis, the distortions are also symmetrical and are combined under the condition that the axis of symmetry of the sweeps coincides with the axis of symmetry of the images. The split image of the object from the image divider 3 is projected through the corresponding optical filter 5 onto the photosensitive layer 4, on which the potential relief of two symmetric color-separated images is formed. When reading the potential relief on the photosensitive layer, the received video signal with frequency compaction contains video information of various separations in a checkerboard pattern. From the output of the photoelectric converter 6, the video signal is fed to the coding unit 7, from the output of which through the switch 8 is fed to the matrix 10, which forms the color signals R, G, B. To reproduce the achromatic parts of the object 1 without blinking, two filtered ones are formed on the photosensitive layer 4 images in the form of stripes, with each of the two decoded video signals corresponding to a pair of opposite colors. A method of optoelectronic color image transmission, including the simultaneous separation of an optical color image into two symmetric optical color images, spectral selection of each symmetric optical color image and their subsequent projection onto the photosensitive layer of the photoelectric converter, converting each symmetric optical color image video signal by sequential reading of each of the two separated symmetts color images, in which case the reading is carried out by interlacing, coding
