Title: Schaltungsanordnung zum Mischen zweier Farbvideosignale durch Farbstanzen
IPC: H04N9/75
Filed: 1982-04-08
Granted: 1985-02-07
Abstract: Ein breitbandiges Chroma-Key-Schaltsignal wird aus Chrominanzsignalen mit niedriger Bandbreite in einem Videosignal dadurch erzeugt, daß zunächst in herkömmlicher Weise ein Chroma-Key-Schaltsignal aus diesen Chrominanzsignalen erzeugt wird und daß sodann hochfrequente Übergangskomponenten in dem entsprechenden Luminanzsignal festgestellt werden. Diese hochfrequenten Luminanzsignalkomponenten werden dann dem Schaltsignal in einer Weise hinzuaddiert, daß sichergestellt ist, daß ihre Polaritäten passen, wodurch ein Chroma-Key-Schaltsignal mit höherer Bandbreite erzeugt wird. Dieses Schaltsignal wird zur Steuerung von Überblend-Verstärkern herangezogen, durch die entweder die Videosignale einer ersten Szene oder einer zweiten Szene mit linearen Übergängen zwischen diesen Videosignalen während des Umschaltens abgegeben werden.
