Abstract

Es ist bekannt, in Sichtgerätesteuerungen Bildwiederho­ lungsspeicher einzusetzen, dessen Zellen je einem Bildpunkt zugeordnet sind, synchron mit der Abtastung des Bildschirms des Sichtgerätes auszulesen und die ausgelesenen Signale in einer Farbtabelle zu decodieren. Ferner ist es bekannt, darzu­ stellende Zeichen als Zeichensignale zu codieren, die zur Dar­ stellung des Zeichens in einem Zeichengenerator decodiert werden. Gemäss der vorliegenden Erfindung werden die Aus­ gangssignale des Zeichengenerators (ZG) in erste Stellen der Zellen des Bildwiederholungsspeichers (BWSP) und Attribut­ signale in weitere Stellen eingetragen, wobei die Attributsigna­ le für innerhalb eines Zeichenfeldes gelegene Bildpunkte gleich sind. It is known to replay images in display control systems use memory, the cells of each one pixel are assigned in synchronism with the scanning of the screen read out the display device and the read signals in to decode a color table. It is also known to do so encode characters as character signals that are used to represent position of the character decoded in a character generator will. According to the present invention, the Aus output signals of the character generator (ZG) in the first digits of the Refresh Memory (BWSP) cells and attribute signals entered in further places, the attribute signa le is the same for pixels located within a drawing field are.

Hauptanwendungsgebiet der Erfindung sind Graphiksicht­ geräte. The main field of application of the invention is graphics view equipment.
