Abstract

Image display system with storage of data of images to be displayed. Image display systems are known which can at the same time display an image of a first source (MP) and an image of a second source (RP), with the image of the second source (RP) being reduced in its spatial dimensions. In order to permit a simultaneous image display, the two images are separately stored and processed. According to the invention, the two images are stored in a single memory (4). Prior to the storage a processing of the image of the second source is carried out and this image is stored on a consecutive-line basis in the line scan gaps of the image of the first source in the common main memory. The line scan gaps of the image of the first source are utilised for storage. During the period of the line scan gaps, a) that line of the second source which is to be stored is split up into two parts or b) the subsequent line of the first source is delayed (21). The invention is employed in image display systems. <IMAGE>
