Abstract
An axially symmetrical image is interrogated by means of a Z-shaped scanning raster to permit a simple color picture recording, which however contains all subjectively necessary elements. A scan of each of the two symmetrical images with a quadrupled interlace raster is produced. Video signals are repeated prior to image reproduction in order to avoid line creep. Repetition of one and the same video recording can be performed line by line, for example for video films intended for domestic use, and can be performed frame by frame for studio reproduction.
Claims8
In a system for optoelectronic transmission of an image original (1) radiated in at least two beams having wave-length distributions which differ from each other by being simultaneously projected through a lens (2) and an optical image splitter (3) to form two adjacent images (4,5) on a photosensitive coating surface (11) of photoelectric transducer means (6), the method of converting the two images (4,5) into two electric video signals (9,10) by raster scanning of the photosensitive coating surface (11) of the photoelectric transducer means (6), including the steps of:
- generating the two images (4,5) adjacently disposed in surface aligned, mirror image configuration on said surface (11) in axial symmetry with respect to each other and with respect to a line scanning direction (13) establishing brightness distributions for the two images that are symmetrical for a monochrome version of the image original (1);
- scanning the two images along two scanning rasters (7,8) positioned in approximately axially symmetrical configuration with respect to each other and with respect to the line scanning direction (13);
- and interlinking said scanning rasters with each other line by line with respect to time.
In an opto-electronic image transmission system having an image surface intersected by a symmetry axis between two mirror images projected thereon by optical splitting of an original image from which video signals are generated for remote image reproduction, the method of enhancing said image reproduction including the steps of:
- scanning the two mirror images on said surface along scanning rasters in substantially symmetrical relation to each other relative to said symmetry axis to produce interlaced color separation scans of the original image;
- and repeating said scanning with respect to at least one of the two mirror images in out-of-phase relation to form at least one of the interlaced color separation scans.
