Abstract

L'invention concerne un générateur d'effets spéciaux d'images à bords flous, et destiné à combiner deux signaux d'image. Le bord flou est obtenu par une commutation répétitive entre les deux signaux d'image, dans la région limite, avec un rapport d'impulsion qui augmente de façon progressive. Cet effet est obtenu uniquement avec des circuits numériques. Application à la télévision.
