Abstract: 720,182. Television. PYE, Ltd. Oct. 27, 1952 [Oct. 26, 1951], No. 25091/51. Class 40(3). A composite television picture is produced by combining together signals representative of a desired background scene, signals representative of a foreground object and signals representative of a silhouette of this object against a plain background. The plain background 1 is illuminated by ultra-violet light from sources 2 and the foreground objects 3 by visible light (from which the ultraviolet component has been filtered out) from source 4 and the complete scene is imaged on the photo-cathodes of image-type signal generating tubes 12, 13 by means of a lens 19 and optical beam splitter 11, a filter 10 passing only ultra-violet light being interposed in the optical path of tube 12 and a filter 16, passing visible light but excluding ultra-violet light, interposed in the optical path of tube 13. Scanning of the tubes is effected by imaging on the two photo-cathodes, via the beam splitter 11 and filters 10, 16, the luminous raster produced by a " flying-spot scanning tube 14 the screen of which employs a phosphor having equal radiation in the visible and ultra-violet ranges passed by the filters. The signals thus generated are supplied, via amplifiers 17, 18, to a mixing circuit 9 to which is also supplied signals representative of a desired background scene 6 generated by means of a conventional television camera 5. The three trains of signals are supplied to mixer 9 with such polarities that the output signals available at terminal 20 comprise signals representative of the foreground objects 3 and of the desired background 6, the latter signals being blocked out in synchronisms with the generation of the former signals.
