Abstract

Bekannte Sichtgeräte enthalten eine Steuerung mit einem Bildspeicher (BSP1), in dessen Zellen, die jeweils einem Bildelement zugeordnet sind und synchron mit der Darstellung der Bildelemente auf dem Sichtgerät (SG) ausge lesen werden, Bilddaten gespeichert sind. Known vision devices include a controller with an image memory (BSP1) are read out in the cells, which are each associated with a picture element and in synchronism with the presentation of the picture elements on the display device (SG), image data is stored. Gemäß der vorlie genden Erfindung werden zum Darstellen von mehreren Bildern, die sich teilweise überdecken, Bilddaten nur für diejenigen Bildelemente in den Bildspeicher (BSPI) eingetra gen, welche sichtbar sein sollen. According to the invention will be vorlie constricting for displaying a plurality of images, which overlap in part, image data for those pixels in the image memory (BSPI) eingetra gene which are to be visible. Hierzu sind in den Zellen des Bildspeichers (BSPI) Schreibschutzsignale speicherbar, welche bei einem Schreibbefehl ausgelesen werden und das Einschreiben von neuen Bilddaten sperren. For this purpose, in the cells of the image memory (BSPI) write-protect signals can be stored, which are read out at a write command and lock the writing of new image data.
Hauptanwendungsgebiet der Erfindung sind Sichtge räte. Main applications of the invention are Sichtge councils.
