Controller for cursor positioning on a display medium

摘要

The present invention relates to the processing of cursor information for the display of a cursor on a display medium. Positional information for the cursor is provided by means of an input device which generates signals that are received by a control element which converts this information into cursor video signals to provide the cursor display. The cursor control element processes the vertical and horizontal position coordinate information such that the cursor displayed is independent of any characters being displayed on the medium.
