Description

Einrichtung zur Bildzerlegung bzw. Bildzusammensetzung für die Zwecke des Fernsehens Es ist bekannt, bei Fernsehern die Bildzerlegung oder Bildzusammensetzung mit Hilfe einer rotierenden Lochscheibe zu bewirken, deren .durchweg gleich große Löcher im Linienzuge einer archimedischen Spirale angeordnet sind. Der Abstand je zweier Löcher entspricht dabei der Breite, die Ganghöhe der ganzen Spirale der Höhe des Bildfeldes (Nipkowsche Scheibe). Man hat bei dieser Anordnung auch mehrere Gänge der Lochspirale vorgesehen und dabei, um immer nur einen Bildpunkt abzutasten bzw. - zu registrieren, durch eine Hilfsvorrichtung dafür Sorge getragen, daß von den vorgesehenen Lochgängen in jedem Augenblick nur einer für das Licht freigegeben wird, die übrigen also abgeblendet sind.Device for image decomposition or image composition for the purposes of television It is known, in televisions, the image decomposition or image composition to effect with the help of a rotating perforated disk, whose. consistently the same size Holes are arranged in the line of an Archimedean spiral. The distance ever two holes corresponds to the width, the pitch of the entire spiral corresponds to the height of the image field (Nipkow disk). With this arrangement you also have several aisles of the spiral hole and in order to only scan or scan one pixel at a time. - to register, ensured by an auxiliary device that of the provided holes only one released for the light at any given moment the rest are dimmed.

Gemäß vorliegender Erfindung. wird nun der Wechsel der Lochgänge und damit der Teilgebiete des Bildes, die momentan abgetastet bzw. belichtet werden, durch Unterteilung der sender- und empfängerseitigen Umwandlungsorgane von Helligkeit in Stromstufen und umgekehrt bewerkstelligt, indem diese Organe in einer Anzahl gleich derjenigen der Lochgänge in richtiger Lage angeordnet und im geeigneten Takte umgeschaltet werden. Es würden also z. B. bei Verwendung einer Dreifachspirale drei Senderphotozellen vorzusehen sein, die im richtigen Wechsel umgeschaltet werden bzw. drei Empfängerleuchtflächen, deren Helligkeit trägheitslos durch Lichtrelais, Kerrzellen, Glimmlampen o. dgl. gesteuert wird. Dies ist in der Abbildung veranschaulicht, in der q. die Scheibe mit drei Lochspiralen darstellt, währ2-nd 5, 6, 7 z. B. drei getrennte Kathodenflächen einer Neon-Glimmlampe bedeuten, die durch einen Verteiler ä abwechselnd an die vom Empfänger gesteuerte Stromquelle 9, etwa in dien Anodenkreis des letzten Verstärkerrohres, geschaltet werden. Der Verteiler macht in dem gewählten Falle eine Umdrehung auf drei Umdrehungen der Scheibe q..According to the present invention. is now the change of holes and so that the sub-areas of the image that are currently being scanned or exposed, by subdividing the sender and receiver side conversion organs of brightness accomplished in stream stages and vice versa by placing these organs in a number like that of the holes arranged in the correct position and in a suitable cycle be switched. So it would z. B. when using a triple spiral three Transmitter photocells must be provided, which are switched in the correct alternation or three receiver luminous surfaces, the brightness of which is inertially due to light relays, Kerr cells, glow lamps or the like. Is controlled. This is illustrated in the figure, in the q. represents the disk with three spiral holes, while 2-nd 5, 6, 7 z. B. three mean separate cathode surfaces of a neon glow lamp, through a distributor Alternately to the power source 9 controlled by the receiver, for example in the anode circuit of the last amplifier tube. The distributor makes in the chosen one Fall one turn to three turns of the disc q ..
