ABSTRACT:
In order to enable the gentlest possible scrolling of an image to be presented on a display unit, without restricting the scrolling range and with a low outlay, an image area is defined that is larger than the image area that can be presented on the display unit. This larger image area is subdivided into a number of image area sections to which the image data of a corresponding memory section of a frame buffer provided for storing the image data of the image area are assigned by means of corresponding address information items.
