Description

Verfahren zum Entzerren oder Verzerren von Bildern Es ist für viele Zwecke notwendig, ein vorgegebenes Bild, beispielsweise eine Flugzeugaufnahme, zu entzerren oder ein bestimmtes naturgetreues Bild, "beispielsweise für Trickfilm, zu verzerren. Die dazu erforderliche Beeinflussung des Lichtstrahlenganges läßt sich bekanntlich auf rein optischem Wege ausführen, z. B. mittels verzerrender optischer Systeme oder. durch schiefwinklige Projektion.Method of Correcting or Distorting Images It is common to many Purposes necessary to a given image, for example an airplane picture rectify or a certain lifelike image, "for example for animation, to distort. The necessary influencing of the light beam path can As is known, perform purely optically, z. B. by means of distorting optical Systems or. due to angled projection.

Soll dabei der Grad der Entzerrung stetig veränderlich sein, so sind bei der schiefwinkligen Projektion umfangreiche Lenkergetriebe erforderlich, während stetige Änderung bei verzerrenden optischen Systemen im allgemeinen praktisch nicht möglich ist.If the degree of equalization is to be continuously variable, then are extensive steering gear is required for the oblique projection, while steady change in distorting optical systems is generally practically non-existent is possible.

Gemäß der Erfindung werden solche Schwierigkeiten dadurch umgangen, daß das zu entzerrende oder zu verzerrende Bild durch Lichtstrahlen auf die Photokathode eines elektronenoptischen Bildwandlers projiziert wird und der daraufhin von der Kathode ausgehende, das Elektronenbild auf dem Leuchtschirm des Bildwandlers entwerfende Elektronenstrahlengang durch Anwendung elektronenoptischer Verzerrungslinsen oder durch elektrische oder magnetische Strahlenablenkung beeinflußt wird. Dabei ist der Verzerrungsgrad auf verhältnismäßig einfachem Wege in weiten Grenzen veränderbar.According to the invention, such difficulties are circumvented by that the image to be rectified or distorted by light rays on the photocathode an electron-optical image converter is projected and then from the Outgoing cathode, creating the electron image on the fluorescent screen of the image converter Electron beam path by using electron optical distortion lenses or is influenced by electrical or magnetic beam deflection. It is the degree of distortion can be changed within wide limits in a relatively simple way.

Insbesondere läßt sich auch eine stetig veränderliche Verzerrung lediglich durch stetiges Ändern der elektrischen oder magnetischen Ablenkfelder, also durch einfache schaltungstechnische Maßnahmen erzielen. Als elektronenoptische Verzerrungslinse kann z. B. eine flachgedrückte Zylinderelektrode verwendet werden.In particular, a continuously variable distortion can only be achieved by constantly changing the electrical or magnetic deflection fields, i.e. by achieve simple circuitry measures. As an electron optical distortion lens can e.g. B. a flattened cylinder electrode can be used.

PATENTANSPRUCH: Verfahren zum Entzerren oder Verzerren von Bildern, dadurch gekennzeichnet, daß das Bild durch Lichtstrahlen auf die Photokathode eines elektronenoptischen Bildwandlers projiziert wird und der daraufhin von der Kathode ausgehende, das Elektronenbild auf dem Leuchtschirm des Bildwandlers entwerfende Elektronenstrahlengang durch elektronenoptische Verzerrungslinsen oder durch elektrische oder magnetische Strahlenablenkung beeinflußt wird. Claim: Method for rectifying or distorting images, characterized in that the image is projected by light beams onto the photocathode of an electron-optical image converter and the electron beam path which then emanates from the cathode and creates the electron image on the fluorescent screen of the image converter is through electron-optical distortion lenses or through electrical or magnetic beam deflection is influenced.
