Filed: 2000-12-12
Abstract: PURPOSE: A method of controlling an OSD position of an image display system is provided to adjust the horizontal start position of OSD according to an input horizontal frequency so as to display OSD at the same position for the same OSD mode. CONSTITUTION: When a user inputs an OSD start command(S100), OSD position information is detected from an inner memory(S200). It is judged if the detected OSD position information corresponds to one of predetermined OSD modes(S300). When the mode of the detected OSD position information is judged, the horizontal frequency currently being inputted is classified in accordance with a predetermined frequency domain(S400). The central coordinate value of OSD is calculated using the horizontal frequency and the central coordinate values is moved in vertical and horizontal directions according to the judged OSD mode to determine the horizontal start position of OSD(S500). The OSD is displayed at the determined OSD horizontal start position(S600).
