Abstract:
A method for use on a display system having an OSD unit, a pointing device, and a display screen, for the purpose of enhancing a resolution of a cursor movement on the display screen, the display screen being partitioned into an array of OSD blocks, the OSD blocks being capable of displaying a predesigned OSD symbol; the method comprising:partitioning the OSD blocks into an array of subblocks, wherein one of the subblocks represents one resolution unit for the cursor movement;providing a set of fragmented cursor patterns, the fragmented cursor patterns being stored as one OSD symbol with respect to one of the subblocks in corresponding one of the OSD blocks and being combined to form a cursor pattern for displaying on the display screen, in which the fragmented cursor patterns are retrievable for displaying in a specified one of the OSD blocks in response to a particular movement of the cursor over the display screen;in response to a cursor-movement control from the pointing device, detecting which one of the subblocks the pointing device is currently pointing at and in which direction the cursor is being moved;based on the detection results, retrieving the corresponding set of fragmented cursor patterns; anddisplaying the retrieved set of fragmented cursor patterns respectively at desired one of the OSD blocks on the display screen to be visually combined to appear as a full cursor pattern.
