ABSTRACT:
A method and apparatus for recording and superimposing image information on the target of a scan converter tube. The image information is supplied in the form of an electric video signal by means whereof the electron beam projected from the cathode of the tube onto the target is modulated so as to form a charge image. The scan converter tube is alternatingly operated in the beam landing mode and in the secondary emission mode respectively.
