Definitions

  • the invention relates to a device for storing image information displayed on a partial area of a monitor, in particular a code shown, with a the monitor surface by means of an effective on the monitor side Adhesive layer attachable storage medium made of photosensitive Material.
  • Such a device is from the German patent application DE-A-43 12 185 known.
  • the one in this patent application The invention described was based on the object of a device to create with any kind of television broadcast can be made more interesting with which the viewer is animated to participate and through which the television channels Can receive information about the broadcast participation.
  • this device poses the problem that the information displayed on the screen is conditional blurred by the thickness of the glass envelope of a screen is displayed on the screen surface so that the information presented in certain cases is not absolute can be stored sharply on the photosensitive material.
  • An object of the present invention is that described in German patent application DE-A-43 12 185 Device for storing on a partial area of a To design monitor displayed image information so that the information displayed on the screen is as possible sharp or as clearly recognizable as possible on the photosensitive Material can be saved.
  • this object is achieved in that the photosensitive material on a flat carrier medium applied and there on the monitor side only in certain, from each other spaced areas is effective.
  • the inventive feature according to which the photosensitive Material applied to the carrier medium and there on the monitor side is effective includes all possible arrangements of Carrier medium and photosensitive material, in which from Monitor coming light a store in the photosensitive Material, i.e. the photosensitive Material can be on the monitor side of the carrier medium as well- z. B. when using a transparent carrier medium - On the side of the carrier medium facing away from the monitor be arranged.
  • the individual effective areas are each ineffective Areas separated from one another and thus spaced apart ensures that everyone is saved area of the photosensitive material determined by information really only for this area Light receives, receiving from for neighboring areas certain light information by the provision of the ineffective Areas is excluded. That way it is possible to have a largely sharp image on all effective Imaging areas of the photosensitive material especially translucent areas of the mask or aperture layer are assigned.
  • a program When a program is broadcast, a appears on the screen Symbol shown, the geometry is selected so that only very specific effective areas of the photosensitive Material are exposed.
