| 1. A method for rendering an object on a display screen, comprising the steps of:
buffering a plurality of pixels in a plurality of line buffers;
determining a boundary of the object based on the buffered pixels;
determining a direction of the boundary;
testing if a pixel in the line buffers is in motion and applying one of a plurality of filter coefficients if the pixel is
in motion, wherein the plurality of filter coefficients define a modified median filter having a predetermined threshold;
and
interpolating a new pixel in the direction of the boundary through a combination of de-interlacing and vertical/diagonal scaling
operations.
